Hello and welcome to Learning English, 00:04
a daily 30 minute program from the Voice of America. 00:07
I'm Anna Matteo. 00:12
And I'm Bryan Lynn. 00:13
This program is aimed at English learners. 00:16
So we speak slowly and we use words and phrases, 00:20
especially written for people 00:26
learning English. 00:29
On today's show, 00:32
Anna Mateo brings us words and their stories. 00:35
Jill Robbins has a story on a hospital in Venezuela 00:39
where old toys find new life. 00:44
And we also have the weekly science report. 00:48
We will end the program with a lesson of the day. 00:53
This time, Andrew Smith and Joe Robbins discuss 00:57
how to correctly use the expressions 01:02
supposed to and ought to. 01:06
But first. 01:09
One by one, volunteers rescue and repair 01:12
toys that show the marks of use. 01:16
They sold clothing and brush fur and hair. 01:20
Add filling and dress the toys. 01:24
The workers 01:27
are fixing them to again be given to children. 01:28
This is the work of the hospital for soft toys, 01:32
a project in Venezuela's capital Caracas. 01:36
The effort began with a mother's question what do you do with all the toys? 01:40
Once children outgrow them? 01:46
About 60 volunteers 01:49
now meet at least twice a week. 01:51
They work on Barbie dolls, toy bears, and baby dolls. 01:54
The children have left behind. 01:58
The group estimates it has recycled about 70,000 toys 02:01
in the past seven years. 02:06
Its volunteers work faster around the Christmas holiday. 02:09
Hillary Acosta is a 63 year old architect 02:14
who represents the hospital for Soft toys. 02:19
She said the idea came 02:23
from a teacher named Lillian Glueck. 02:25
In 2017, Glueck was looking for something 02:28
to do with her children's toys as they grew older. 02:32
She did not want to 02:36
throw them out or let them fall apart. 02:37
She decided to wash them, 02:41
fix them up and donate them to children 02:43
staying in the University Hospital of Caracas. 02:46
The effort was popular. 02:50
So a few months later, 02:53
she opened the hospital for soft toys at her home. 02:55
It is a nonprofit foundation that also collects and repairs 03:00
other toys and educational games. 03:04
The foundation receives donations from other countries 03:08
that can include school supplies, diapers, shoes, 03:12
food and candy. 03:16
All have been welcomed in a country 03:19
that has seen years of economic crisis 03:21
and renewed political unrest. 03:25
After July's election, 03:27
Sylvia Haber has volunteered for almost three years. 03:30
She is 72 years old. 03:35
She said that smoothing 03:38
a soft toys, fur or fixing adults hair for another child to care for 03:40
is also helpful for the volunteers. 03:46
By doing this, 03:50
all of us who come here are in therapy, 03:52
a therapy of support for one another. 03:55
Hiba said. 03:57
MiRNA morales 04:00
is a 76 year old teacher and volunteer. 04:01
She called it one of the best experiences I've ever had. 04:05
Maria Pelayo, who is 84 years old, 04:10
said the work is not difficult 04:13
because all the volunteers know how to make or repair clothing. 04:15
On some days it seems there are not enough toys to repair. 04:20
But then someone arrives at the door 04:25
with more boxes and bags full of toys. 04:28
The toys are delivered to hospitals and schools 04:32
in poor areas, but also to homes for older people. 04:34
Anyone who needs a little bit of affection, Haber said. 04:39
Each restored doll comes with a message 04:44
advising its new owner to recycle it when they no longer want it. 04:48
Hello. 04:53
I am your new friend, it says. 04:54
I am a doll with experience 04:57
because I played with another girl. 04:59
Love me and take care of me. 05:02
And I will do the same with you. 05:04
When you grow up, give me to another girl 05:07
who will love me and play with me like you. 05:10
I'm Jill Robbins. 05:14
And now, words and their stories 05:20
from VOA learning English. 05:23
In many parts of the world, 05:30
temperatures are dropping for the winter season. 05:32
But even for those in warm weather, 05:36
our show on the word cold 05:39
will help your English. 05:42
Cold is not just 05:45
an adjective describing temperature. 05:47
It can also describe stopping something 05:51
suddenly and surprisingly. 05:54
It also means starting or doing 05:58
something without preparation. 06:01
These definitions give us several expressions and idioms. 06:04
When someone or something stops cold, 06:10
it stops completely, suddenly 06:14
and perhaps with surprise. 06:17
For example, I was surprised 06:21
when my car stopped cold on a recent trip. 06:24
I had just had it fixed. 06:27
With this expression, we often say 06:31
the thing or person being stopped. 06:33
So in that example I could say 06:37
engine trouble stopped my car cold. 06:40
When we stop someone cold, 06:45
we completely stop them from doing something 06:47
suddenly or immediately. 06:50
Here's an example. 06:53
The sunset was so beautiful 06:56
it stopped me cold. 07:00
Sometimes we add in my tracks to this expression. 07:02
Such as the sunset was so beautiful 07:07
it stopped me cold in my tracks. 07:13
Other variations of this expression include 07:16
to stop someone dead in their tracks 07:20
and to stop someone on a dime. 07:24
They all mean the same thing. 07:29
Something or someone has come to a stand still, 07:31
and we can use them the same way. 07:36
Now let's talk about how we use 07:41
cold in the business world. 07:43
Sometimes we need to call 07:48
someone who does not know us 07:49
and we do not know them. 07:53
These are cold calls. 07:56
A cold call can also 08:00
be a visit to a person or business. 08:01
And usually we want to sell something. 08:05
For example, a sales 08:10
person may have a cold call list 08:12
to get new business. 08:15
Cold calls, whether on the phone 08:18
or in person, are unsolicited. 08:21
This means that no one asked 08:25
or requested contact 08:27
in business and also in life. 08:31
If you come to something cold 08:35
or come into something cold, you are not prepared. 08:37
Here is an example. 08:43
Last week I came into the meeting cold. 08:45
I hadn't read any of the materials. 08:49
However, if you come in 08:52
from the cold, you are in luck. 08:54
It means you rejoin a group 08:58
or a normal society again 09:01
after being outside. 09:04
We often use this expression 09:07
to describe someone like a spy 09:09
who was able to come in from the cold 09:13
and enjoy a normal life, 09:16
come in from the cold 09:20
can also be used when someone or something 09:21
becomes popular, accepted or active again 09:25
after being unpopular or unaccepted 09:30
and inactive for a time. 09:34
And that's all the time we have for this. 09:37
Words and their stories. 09:40
Until next time. 09:41
I'm Anna Mateo. 09:43
The American space agency. 10:12
NASA says it has found the likely cause 10:15
of a crash that grounded its Mars helicopter. 10:20
Ingenuity. 10:24
The finding comes after NASA said it had carried out 10:26
the first aircraft accident investigation 10:31
on another world. 10:36
Ingenuity arrived on Mars along with NASA's 10:38
Perseverance Explorer, or rover, 10:43
in February 2021. 10:46
The experimental helicopter took its last flight, 10:50
number 72, in January. 10:55
That flight ended in a hard landing 10:59
on the Martian surface in April 2021. 11:02
Ingenuity became the first aircraft to complete a powered, 11:07
controlled flight on another planet. 11:13
The aircraft was built to test takeoff, short 11:17
flight, and landing operations. 11:22
The flights on Mars aimed to support 11:25
NASA's efforts to build new aircraft 11:29
that can fly in the atmosphere of other planets. 11:33
Engineers from NASA's 11:38
Jet Propulsion Laboratory in California 11:40
fully investigated Ingenuity's 11:44
last flight on Mars. 11:48
They found the cause of the crash 11:51
was linked to the helicopter's navigation system. 11:53
That camera based system 11:58
was not able to collect dependable data 12:01
on elements of the Martian surface 12:05
to support a safe landing. 12:08
A detailed final report on the accident 12:11
is to be issued in the coming weeks, 12:15
but the engineers have already described their main findings 12:18
in a statement published online. 12:24
They said the helicopter's last flight 12:28
saw the aircraft climb to about 12m where it stayed, or hovered, 12:31
while capturing images of the Martian surface. 12:38
Data records show ingenuity began its planned descent 12:43
after about 19 seconds by 32 seconds. 12:48
The helicopter was back on the surface and was no longer 12:54
sending communication signals. 12:58
The next day, ingenuity team members 13:02
reestablished communications 13:05
and received images from its last flight. 13:08
The images showed the aircraft suffered 13:13
severe damage to its rotor blades. 13:17
NASA explained that Ingenuity's navigation 13:21
system plays an important part in collecting data 13:25
about the surface, to ensure the aircraft 13:30
can complete a smooth landing. 13:34
The helicopter uses a camera that points downward, 13:37
capturing information about what is below the craft. 13:42
In past flights, the engineers said. 13:47
The camera was able to find smooth, 13:50
suitable landing possibilities, 13:53
but NASA said during the final flight, 13:57
the helicopter was traveling in an area 14:00
with very few surface features for the camera to capture. 14:04
This meant the aircraft's navigation system 14:10
could not find enough of these features 14:14
to choose a good landing spot. 14:17
At the time, ingenuity was operating. 14:20
Together with NASA's perseverance rover 14:24
in an area of Mars known as Jezero Crater, 14:28
the images recovered from ingenuity 14:33
suggested the navigation systems inability 14:36
to pick up surface features that made 14:41
the helicopter descend too fast. 14:44
The hard landing on a sand hill is believed 14:48
to have caused the helicopter to turn over and roll. 14:52
The engineers said images 14:58
showed that all four of Ingenuity's rotor blades 15:00
broke at their weakest point. 15:05
The damaged blades also caused the aircraft to shake. 15:08
Events related to the crash led to increased power demand, 15:14
which resulted in the loss of communications. 15:19
Although the crash ended Ingenuity's flight operations, 15:24
NASA said it is still able to provide 15:29
and send back weather information 15:33
and other kinds of data. 15:36
The space agency says this information 15:39
could be helpful in designing future aircraft 15:42
or other explorers to be sent to Mars. 15:46
Teddy Zito's is Ingenuity's 15:51
project manager, he said in a statement. 15:54
One major thing the team learned was that future 15:59
aircraft designed for space travel do not 16:02
necessarily need to be large flying machines. 16:07
Thanatos added that Ingenuity's longevity 16:11
signal tests that not everything needs to be bigger, 16:15
heavier, and radiation hardened 16:20
to work in the Martian environment. 16:23
With this in mind, NASA 16:27
engineers have been testing smaller, lighter flying vehicles 16:29
with limited electronics in order to produce future helicopters 16:35
that can make a large number of smaller 16:41
exploration trips. 16:44
Santos shared details about one 16:47
aircraft NASA is currently developing. 16:50
It is called the Mars Chopper. 16:54
Rotorcraft. 16:56
Thanatos said chopper is about 20 times heavier than engines. 16:58
City developers say it would be built to carry several kilometers 17:04
of science equipment, while self exploring 17:10
distant areas of Mars. 17:14
Chopper would also have a much longer travel ability, 17:17
flying up to three kilometers in a day. 17:22
Ingenuity's longest flight was 704m. 17:26
Thanatos said that overall 17:31
ingenuity has given us the confidence and data 17:34
to envision the future of flight at Mars. 17:39
And now it's time for the lesson of the day. 17:56
On the Learning English podcast. 17:59
My name is Jill Robbins, and I'm joined by Andrew Smith. 18:01
I, Andrew. Hi, Jill. 18:05
Our lesson is based on our video series Let's Learn English. 18:07
The series shows animal tale 18:12
in her work in life in Washington, DC. 18:14
Here's Anna introducing herself. 18:17
Hello, my name is Anna Mateo. 18:20
In lesson 28 of level two of the series, Anna and her friend 18:25
Kelly are helping with a research project about birds. 18:30
They are trying to count the number of birds 18:36
they see and hear in an area near their office. 18:38
Unfortunately, Anna does not find many birds. 18:44
Instead, she finds something else. 18:48
Listen to find out what that is. 18:52
And we're going to listen for the expressions. 18:54
Supposed to and ought to. 18:59
And we'll explain 19:03
different ways native speakers use those expressions. 19:05
But now let's listen to the first part of lesson 28. 19:10
Oh, Anna. 19:21
There you are. 19:23
I am so glad we joined the great city bird count. 19:24
Aren't you? No. 19:28
Today has been a bust, a flop. 19:31
A bummer. 19:34
I'm sensing a little disappointment. 19:37
A little? 19:40
Well, my official birdwatching form is almost full. 19:42
I've only seen pigeons. 19:46
Lots and lots of pigeons. 19:49
But I did write down 19:52
some other valuable information. 19:54
Did you find a bird's nest? No. 19:57
I found ten 20:02
ice cream trucks in this five block area. 20:03
Their music seems to follow me everywhere. 20:06
We're supposed to be counting birds, not ice cream trucks. 20:10
This is important scientific work. 20:14
Well, when you want ice cream, 20:18
my data will be pretty important. 20:20
Anna only saw one kind of bird, a pigeon. 20:25
And the music from the trucks selling ice cream got Anna's attention. 20:28
More than the sound of birds did. 20:33
That's why she says no. 20:36
Today has been a bust, a flop. 20:40
A bummer, 20:44
a bust. 20:46
A flop, and a bummer 20:47
are all informal ways of saying that something you were trying 20:50
or hoping to do did not work and 20:55
was really very disappointing. 20:59
Anna was disappointed, but there is a good reason 21:02
she could not count the birds. 21:05
Her office in Washington, D.C. 21:07
which to tell a secret, is the same as our offices here. 21:10
VOA Learning English is in an area with many tourists. 21:13
And tourists get hungry. 21:18
So there are a lot of food trucks in the area, 21:22
and they play music all day long. 21:27
And they play the same song 21:32
all day long, over and over. 21:34
I used to get so sick of turkey in the straw. 21:37
Yes, they 21:41
do play the same song over and over. 21:42
Anna hears this music and sees 21:45
that many of the trucks are selling ice cream. 21:48
It's hard for her to focus on birds instead of ice cream. 21:52
But she is supposed to focus on birds. 21:56
We're supposed to be counting birds, not ice cream trucks. 22:00
This is important scientific work. 22:04
The modal verb supposed to 22:08
can be used in two ways. 22:11
In this example, Kelly is saying that the expected behavior 22:14
is for Anna to find birds. 22:19
So we can use supposed to. 22:23
When we want to talk about behavior 22:26
we expect other people to do. 22:29
For example, for rules that we generally expect people to follow. 22:32
We can say something like, you're supposed to come to class on time. 22:37
Native speakers also use supposed to 22:42
as a way of saying what is predicted 22:46
or expected to happen in the future. 22:49
For example, we might say it's supposed to rain tomorrow. 22:53
That means it is likely to rain. 22:57
And when you hear 23:01
someone talking quickly or a child speaking, 23:02
you might hear a poster, as in 23:06
you're supposed to eat all your vegetables. 23:09
That's right. 23:12
That's another example of how our pronunciation changes 23:13
when we're speaking quickly. 23:17
Now let's listen to the next part of lesson 28. 23:19
Keep in mind that Anna is also 23:24
very interested in spies. 23:27
Spies are people who try to steal secret information 23:31
from other countries or from other organizations. 23:36
And listen for when Anna uses the modal verb 23:41
ought to know birds. 23:45
Oh wait, there's another ice cream truck 23:48
on a focus on birds. 23:51
Oh, but that truck has my favorite 23:54
flavor banana. 23:56
That man is in the way. 24:00
I can't see the price. 24:02
I wonder what flavor he's getting. 24:04
Strawberry. 24:08
He doesn't seem like a strawberry kind of guy. 24:11
In fact, he doesn't seem like an ice cream truck kind of guy. 24:14
That suit looks expensive. 24:19
Maybe he's a spy. 24:22
You know what that means. 24:24
The ice cream truck driver is a spy. 24:26
Two genius. 24:28
It's a perfect disguise. 24:31
What? 24:34
The man in the suit 24:36
left his briefcase at the ice cream truck. 24:38
I was right. 24:41
He is a spy. 24:42
And he just dropped off. 24:43
Top secret information. 24:44
I got to do something. 24:47
Something needs to be done. 24:49
I need to do something. 24:51
I did it. 25:03
I took the spies briefcase. 25:05
What's that? 25:08
The ice cream truck. 25:09
It's following me. 25:11
It wants the case back. 25:13
I have to hide. 25:16
This is my life now. 25:24
Running scared alone. Oh. 25:26
But awful music. 25:34
It's following. 25:36
Me everywhere. 25:37
Hey. You found my briefcase. 25:39
You caught me. What? 25:42
I mean, I caught you. Well. 25:43
I just want my briefcase. 25:46
All my poems are in their homes. 25:48
You're a poet. 25:51
Well, I'm a lawyer, but I write poems, too. 25:52
So you're not a spy. 25:56
You look. Disappointed. 25:58
No. That's okay. 26:00
It's not your fault. 26:01
Poems are nice, too. 26:03
I guess. 26:05
Once again, others imagination makes her do something unusual. 26:07
In this case, she steals a man's briefcase. 26:12
He uses it to carry his papers. 26:16
On his lucky, she did not get in trouble. 26:20
And honor really ought to think more carefully before she acts. 26:23
Yes, and I think that's good advice for most of us. 26:28
Now, let's hear that part again. 26:32
Where Anna uses the modal ought to. 26:33
I was right. 26:37
He is a spy. 26:38
And he just dropped off top secret information. 26:39
I got to do something. 26:43
Something needs to be done. 26:45
I need to do something. 26:47
The modal ought to can be used in more than one way. 26:50
As Anna uses it here, 26:54
she is making a strong suggestion. 26:57
In this case, it is a suggestion to take action 27:00
to stop someone from spying. 27:04
But native speakers also use ought to as a way 27:08
to make suggestions that are not so strong. 27:11
They often use it to just give advice in an informal way. 27:14
For example, if I see a really good movie, 27:18
I can suggest that Jill see it. 27:22
So I can simply say, hey Jill, 27:26
you ought to see this movie. 27:29
Did you notice Andrew said order because he was speaking quickly? 27:31
So you can use it to make a strong suggestion 27:36
and express disapproval at the same time. 27:39
For example, if students misbehave and don't listen to their teacher, 27:43
the teacher might say to them, you ought to start listening. 27:47
Otherwise you're going to fail. This class. 27:50
In this case, the teacher uses ought to as a way 27:53
of scolding the students 27:56
to scold is to strongly tell 27:59
someone that their behavior is bad. 28:02
At the end of lesson 28, 28:05
Anna guesses that the man's favorite flavor of ice cream is strawberry, 28:08
and then she makes a little joke using an expression about birds. 28:12
What's your favorite flavor? 28:18
Banana. 28:19
Well, my favorite flavor is strawberry. 28:20
How do you know that? 28:23
A little bird told me. 28:25
When we say a little bird told me. 28:31
That is an expression that means we have a special 28:34
or secret way of knowing something about someone. 28:37
And in 28:42
this case, Anna's joke has sort of a double meaning, 28:42
because Anna was spying on the man when he bought the ice cream. 28:45
But at the same time, she could not find any birds for the research project. 28:49
There is always a lot of humor and funny situations 28:54
in the Let's Learn English series. 28:57
And remember that each lesson comes with a lesson plan 29:00
you can download for free from our website. 29:05
Andrew, you know, this episode reminds me we made friends 29:09
with one of the ice cream truck drivers and 29:13
he was so nice. 29:17
Anyway, a little bird is telling me we ought to finish this lesson of the day. 29:19
What do you say? 29:23
I say okay. 29:25
And listeners, remember that you can also find us 29:26
on YouTube, Facebook and Instagram. 29:30
Thanks for listening. 29:34
I'm Andrew Smith. 29:36
And I'm Jill Robbins. 29:37
And that's all the time we have for today's show. 29:40
But join us again tomorrow for another VOA Learning English program. 29:45
I'm Bryan Lynn. 29:52

[English]
Hello and welcome to Learning English,
a daily 30 minute program from the Voice of America.
I'm Anna Matteo.
And I'm Bryan Lynn.
This program is aimed at English learners.
So we speak slowly and we use words and phrases,
especially written for people
learning English.
On today's show,
Anna Mateo brings us words and their stories.
Jill Robbins has a story on a hospital in Venezuela
where old toys find new life.
And we also have the weekly science report.
We will end the program with a lesson of the day.
This time, Andrew Smith and Joe Robbins discuss
how to correctly use the expressions
supposed to and ought to.
But first.
One by one, volunteers rescue and repair
toys that show the marks of use.
They sold clothing and brush fur and hair.
Add filling and dress the toys.
The workers
are fixing them to again be given to children.
This is the work of the hospital for soft toys,
a project in Venezuela's capital Caracas.
The effort began with a mother's question what do you do with all the toys?
Once children outgrow them?
About 60 volunteers
now meet at least twice a week.
They work on Barbie dolls, toy bears, and baby dolls.
The children have left behind.
The group estimates it has recycled about 70,000 toys
in the past seven years.
Its volunteers work faster around the Christmas holiday.
Hillary Acosta is a 63 year old architect
who represents the hospital for Soft toys.
She said the idea came
from a teacher named Lillian Glueck.
In 2017, Glueck was looking for something
to do with her children's toys as they grew older.
She did not want to
throw them out or let them fall apart.
She decided to wash them,
fix them up and donate them to children
staying in the University Hospital of Caracas.
The effort was popular.
So a few months later,
she opened the hospital for soft toys at her home.
It is a nonprofit foundation that also collects and repairs
other toys and educational games.
The foundation receives donations from other countries
that can include school supplies, diapers, shoes,
food and candy.
All have been welcomed in a country
that has seen years of economic crisis
and renewed political unrest.
After July's election,
Sylvia Haber has volunteered for almost three years.
She is 72 years old.
She said that smoothing
a soft toys, fur or fixing adults hair for another child to care for
is also helpful for the volunteers.
By doing this,
all of us who come here are in therapy,
a therapy of support for one another.
Hiba said.
MiRNA morales
is a 76 year old teacher and volunteer.
She called it one of the best experiences I've ever had.
Maria Pelayo, who is 84 years old,
said the work is not difficult
because all the volunteers know how to make or repair clothing.
On some days it seems there are not enough toys to repair.
But then someone arrives at the door
with more boxes and bags full of toys.
The toys are delivered to hospitals and schools
in poor areas, but also to homes for older people.
Anyone who needs a little bit of affection, Haber said.
Each restored doll comes with a message
advising its new owner to recycle it when they no longer want it.
Hello.
I am your new friend, it says.
I am a doll with experience
because I played with another girl.
Love me and take care of me.
And I will do the same with you.
When you grow up, give me to another girl
who will love me and play with me like you.
I'm Jill Robbins.
And now, words and their stories
from VOA learning English.
In many parts of the world,
temperatures are dropping for the winter season.
But even for those in warm weather,
our show on the word cold
will help your English.
Cold is not just
an adjective describing temperature.
It can also describe stopping something
suddenly and surprisingly.
It also means starting or doing
something without preparation.
These definitions give us several expressions and idioms.
When someone or something stops cold,
it stops completely, suddenly
and perhaps with surprise.
For example, I was surprised
when my car stopped cold on a recent trip.
I had just had it fixed.
With this expression, we often say
the thing or person being stopped.
So in that example I could say
engine trouble stopped my car cold.
When we stop someone cold,
we completely stop them from doing something
suddenly or immediately.
Here's an example.
The sunset was so beautiful
it stopped me cold.
Sometimes we add in my tracks to this expression.
Such as the sunset was so beautiful
it stopped me cold in my tracks.
Other variations of this expression include
to stop someone dead in their tracks
and to stop someone on a dime.
They all mean the same thing.
Something or someone has come to a stand still,
and we can use them the same way.
Now let's talk about how we use
cold in the business world.
Sometimes we need to call
someone who does not know us
and we do not know them.
These are cold calls.
A cold call can also
be a visit to a person or business.
And usually we want to sell something.
For example, a sales
person may have a cold call list
to get new business.
Cold calls, whether on the phone
or in person, are unsolicited.
This means that no one asked
or requested contact
in business and also in life.
If you come to something cold
or come into something cold, you are not prepared.
Here is an example.
Last week I came into the meeting cold.
I hadn't read any of the materials.
However, if you come in
from the cold, you are in luck.
It means you rejoin a group
or a normal society again
after being outside.
We often use this expression
to describe someone like a spy
who was able to come in from the cold
and enjoy a normal life,
come in from the cold
can also be used when someone or something
becomes popular, accepted or active again
after being unpopular or unaccepted
and inactive for a time.
And that's all the time we have for this.
Words and their stories.
Until next time.
I'm Anna Mateo.
The American space agency.
NASA says it has found the likely cause
of a crash that grounded its Mars helicopter.
Ingenuity.
The finding comes after NASA said it had carried out
the first aircraft accident investigation
on another world.
Ingenuity arrived on Mars along with NASA's
Perseverance Explorer, or rover,
in February 2021.
The experimental helicopter took its last flight,
number 72, in January.
That flight ended in a hard landing
on the Martian surface in April 2021.
Ingenuity became the first aircraft to complete a powered,
controlled flight on another planet.
The aircraft was built to test takeoff, short
flight, and landing operations.
The flights on Mars aimed to support
NASA's efforts to build new aircraft
that can fly in the atmosphere of other planets.
Engineers from NASA's
Jet Propulsion Laboratory in California
fully investigated Ingenuity's
last flight on Mars.
They found the cause of the crash
was linked to the helicopter's navigation system.
That camera based system
was not able to collect dependable data
on elements of the Martian surface
to support a safe landing.
A detailed final report on the accident
is to be issued in the coming weeks,
but the engineers have already described their main findings
in a statement published online.
They said the helicopter's last flight
saw the aircraft climb to about 12m where it stayed, or hovered,
while capturing images of the Martian surface.
Data records show ingenuity began its planned descent
after about 19 seconds by 32 seconds.
The helicopter was back on the surface and was no longer
sending communication signals.
The next day, ingenuity team members
reestablished communications
and received images from its last flight.
The images showed the aircraft suffered
severe damage to its rotor blades.
NASA explained that Ingenuity's navigation
system plays an important part in collecting data
about the surface, to ensure the aircraft
can complete a smooth landing.
The helicopter uses a camera that points downward,
capturing information about what is below the craft.
In past flights, the engineers said.
The camera was able to find smooth,
suitable landing possibilities,
but NASA said during the final flight,
the helicopter was traveling in an area
with very few surface features for the camera to capture.
This meant the aircraft's navigation system
could not find enough of these features
to choose a good landing spot.
At the time, ingenuity was operating.
Together with NASA's perseverance rover
in an area of Mars known as Jezero Crater,
the images recovered from ingenuity
suggested the navigation systems inability
to pick up surface features that made
the helicopter descend too fast.
The hard landing on a sand hill is believed
to have caused the helicopter to turn over and roll.
The engineers said images
showed that all four of Ingenuity's rotor blades
broke at their weakest point.
The damaged blades also caused the aircraft to shake.
Events related to the crash led to increased power demand,
which resulted in the loss of communications.
Although the crash ended Ingenuity's flight operations,
NASA said it is still able to provide
and send back weather information
and other kinds of data.
The space agency says this information
could be helpful in designing future aircraft
or other explorers to be sent to Mars.
Teddy Zito's is Ingenuity's
project manager, he said in a statement.
One major thing the team learned was that future
aircraft designed for space travel do not
necessarily need to be large flying machines.
Thanatos added that Ingenuity's longevity
signal tests that not everything needs to be bigger,
heavier, and radiation hardened
to work in the Martian environment.
With this in mind, NASA
engineers have been testing smaller, lighter flying vehicles
with limited electronics in order to produce future helicopters
that can make a large number of smaller
exploration trips.
Santos shared details about one
aircraft NASA is currently developing.
It is called the Mars Chopper.
Rotorcraft.
Thanatos said chopper is about 20 times heavier than engines.
City developers say it would be built to carry several kilometers
of science equipment, while self exploring
distant areas of Mars.
Chopper would also have a much longer travel ability,
flying up to three kilometers in a day.
Ingenuity's longest flight was 704m.
Thanatos said that overall
ingenuity has given us the confidence and data
to envision the future of flight at Mars.
And now it's time for the lesson of the day.
On the Learning English podcast.
My name is Jill Robbins, and I'm joined by Andrew Smith.
I, Andrew. Hi, Jill.
Our lesson is based on our video series Let's Learn English.
The series shows animal tale
in her work in life in Washington, DC.
Here's Anna introducing herself.
Hello, my name is Anna Mateo.
In lesson 28 of level two of the series, Anna and her friend
Kelly are helping with a research project about birds.
They are trying to count the number of birds
they see and hear in an area near their office.
Unfortunately, Anna does not find many birds.
Instead, she finds something else.
Listen to find out what that is.
And we're going to listen for the expressions.
Supposed to and ought to.
And we'll explain
different ways native speakers use those expressions.
But now let's listen to the first part of lesson 28.
Oh, Anna.
There you are.
I am so glad we joined the great city bird count.
Aren't you? No.
Today has been a bust, a flop.
A bummer.
I'm sensing a little disappointment.
A little?
Well, my official birdwatching form is almost full.
I've only seen pigeons.
Lots and lots of pigeons.
But I did write down
some other valuable information.
Did you find a bird's nest? No.
I found ten
ice cream trucks in this five block area.
Their music seems to follow me everywhere.
We're supposed to be counting birds, not ice cream trucks.
This is important scientific work.
Well, when you want ice cream,
my data will be pretty important.
Anna only saw one kind of bird, a pigeon.
And the music from the trucks selling ice cream got Anna's attention.
More than the sound of birds did.
That's why she says no.
Today has been a bust, a flop.
A bummer,
a bust.
A flop, and a bummer
are all informal ways of saying that something you were trying
or hoping to do did not work and
was really very disappointing.
Anna was disappointed, but there is a good reason
she could not count the birds.
Her office in Washington, D.C.
which to tell a secret, is the same as our offices here.
VOA Learning English is in an area with many tourists.
And tourists get hungry.
So there are a lot of food trucks in the area,
and they play music all day long.
And they play the same song
all day long, over and over.
I used to get so sick of turkey in the straw.
Yes, they
do play the same song over and over.
Anna hears this music and sees
that many of the trucks are selling ice cream.
It's hard for her to focus on birds instead of ice cream.
But she is supposed to focus on birds.
We're supposed to be counting birds, not ice cream trucks.
This is important scientific work.
The modal verb supposed to
can be used in two ways.
In this example, Kelly is saying that the expected behavior
is for Anna to find birds.
So we can use supposed to.
When we want to talk about behavior
we expect other people to do.
For example, for rules that we generally expect people to follow.
We can say something like, you're supposed to come to class on time.
Native speakers also use supposed to
as a way of saying what is predicted
or expected to happen in the future.
For example, we might say it's supposed to rain tomorrow.
That means it is likely to rain.
And when you hear
someone talking quickly or a child speaking,
you might hear a poster, as in
you're supposed to eat all your vegetables.
That's right.
That's another example of how our pronunciation changes
when we're speaking quickly.
Now let's listen to the next part of lesson 28.
Keep in mind that Anna is also
very interested in spies.
Spies are people who try to steal secret information
from other countries or from other organizations.
And listen for when Anna uses the modal verb
ought to know birds.
Oh wait, there's another ice cream truck
on a focus on birds.
Oh, but that truck has my favorite
flavor banana.
That man is in the way.
I can't see the price.
I wonder what flavor he's getting.
Strawberry.
He doesn't seem like a strawberry kind of guy.
In fact, he doesn't seem like an ice cream truck kind of guy.
That suit looks expensive.
Maybe he's a spy.
You know what that means.
The ice cream truck driver is a spy.
Two genius.
It's a perfect disguise.
What?
The man in the suit
left his briefcase at the ice cream truck.
I was right.
He is a spy.
And he just dropped off.
Top secret information.
I got to do something.
Something needs to be done.
I need to do something.
I did it.
I took the spies briefcase.
What's that?
The ice cream truck.
It's following me.
It wants the case back.
I have to hide.
This is my life now.
Running scared alone. Oh.
But awful music.
It's following.
Me everywhere.
Hey. You found my briefcase.
You caught me. What?
I mean, I caught you. Well.
I just want my briefcase.
All my poems are in their homes.
You're a poet.
Well, I'm a lawyer, but I write poems, too.
So you're not a spy.
You look. Disappointed.
No. That's okay.
It's not your fault.
Poems are nice, too.
I guess.
Once again, others imagination makes her do something unusual.
In this case, she steals a man's briefcase.
He uses it to carry his papers.
On his lucky, she did not get in trouble.
And honor really ought to think more carefully before she acts.
Yes, and I think that's good advice for most of us.
Now, let's hear that part again.
Where Anna uses the modal ought to.
I was right.
He is a spy.
And he just dropped off top secret information.
I got to do something.
Something needs to be done.
I need to do something.
The modal ought to can be used in more than one way.
As Anna uses it here,
she is making a strong suggestion.
In this case, it is a suggestion to take action
to stop someone from spying.
But native speakers also use ought to as a way
to make suggestions that are not so strong.
They often use it to just give advice in an informal way.
For example, if I see a really good movie,
I can suggest that Jill see it.
So I can simply say, hey Jill,
you ought to see this movie.
Did you notice Andrew said order because he was speaking quickly?
So you can use it to make a strong suggestion
and express disapproval at the same time.
For example, if students misbehave and don't listen to their teacher,
the teacher might say to them, you ought to start listening.
Otherwise you're going to fail. This class.
In this case, the teacher uses ought to as a way
of scolding the students
to scold is to strongly tell
someone that their behavior is bad.
At the end of lesson 28,
Anna guesses that the man's favorite flavor of ice cream is strawberry,
and then she makes a little joke using an expression about birds.
What's your favorite flavor?
Banana.
Well, my favorite flavor is strawberry.
How do you know that?
A little bird told me.
When we say a little bird told me.
That is an expression that means we have a special
or secret way of knowing something about someone.
And in
this case, Anna's joke has sort of a double meaning,
because Anna was spying on the man when he bought the ice cream.
But at the same time, she could not find any birds for the research project.
There is always a lot of humor and funny situations
in the Let's Learn English series.
And remember that each lesson comes with a lesson plan
you can download for free from our website.
Andrew, you know, this episode reminds me we made friends
with one of the ice cream truck drivers and
he was so nice.
Anyway, a little bird is telling me we ought to finish this lesson of the day.
What do you say?
I say okay.
And listeners, remember that you can also find us
on YouTube, Facebook and Instagram.
Thanks for listening.
I'm Andrew Smith.
And I'm Jill Robbins.
And that's all the time we have for today's show.
But join us again tomorrow for another VOA Learning English program.
I'm Bryan Lynn.
And I'm Anna Matteo.
