What do you know about Qian

Xuesen?

Qian Xuesen, father of Missile in China, was born in Hangzhou. As an academician, he has contributed greatly to the astronautical industry of the country.

Look at the picture and predict the content of the listening.

1

Before we begin to listen to it,

look at the screen and read the new

words in the material :

astronomer ( 天文学家 )

astronaut ( 宇航员 )

institute ( 研究所 )

Listen to Parts 1 and 2 of the tape for the

first time and write down the main idea.

2

It is about the role of Qian Xuesen in the

development of space technology in

China.

A GREAT CHINESE SCIENTIST

Father of the Chinese space programme

Yu Ping is talking to her friend Steve

Smith about Qian Xuesen and his work

as a rocket scientist.

Listening text

Part 1YP: What do you want to be when you grow up, Steve? SS: I want to be an astronomer and visit stars. I wish to visit Mars one day.YP: I think I'd like to work in the space industry too. I'd like to be a rocket scientist like Qian Xuesen.SS: What did he have to do to become a rocket scientist?

YP: Well, he first studied at university to

be an engineer. Later he went to

America to study for his doctor's

degree. It was then he

began to work on rockets there.

SS: So it was lucky for our space

programme that he came back to

China.

YP: Very much so. There was no work

on space rockets in China before he

began his institute to design and

build rockets to go into space.

SS: Do you think he wanted to travel

into space in one of his rockets?

Part 2

SS: do you think he wanted to travel

into space in one of his rockets?

YP: I have no idea but I believe he

looked forward to the first space

flight by a Chinese astronaut.

SS: Yes. Now that China has already sent

satellites into space. I hope we’ll be

the first to land on Mars. That would

really be something special and if I

were that astronaut I would put Qian

Xuesen's picture on Mars to show

how much we admire his work.

YP: Indeed. He is rightfully called

the father of the Chinese space

programme. He is my hero

and he is why I want to be a

rocket scientist.

SS: Well, we'd better get on with our

homework. We need good grades

to get into university.

YP: Right you are. See you, then.

SS: See you.

1.What did Qian Xuesen study first? Qian Xuesen first studied to be an engineer.2.What experience did he get in America that was very useful for China? In America he began to work on space rockets so that he was able to develop a space programme when he came back to China.

Answer the questions3

3.What was Qian Xuesen's main

achievement when he returned to

China?

These questions may help you:• What kind of scientific job do you

want to do? • What education will you need?

5 In pairs discuss a scientific job you might choose in the future.

•What personality will be needed?

•How long will the training take?

•What work experience would be

useful?

•How will you prepare for this career?

•Why are you so interested in this job?

MIKE: What do you want to do when

you grow up?

LI RU: I want to build robots. I will have

to do a physics and mathematics

degree in China.

Sample conversation:

After that I hope to go abroad

to Reading University in

England where you can study

all about robots. There is a

special cybernetics( 控制论 )

department there.

MIKE: Why personality will be needed

for that job?

LI RU: I think I need to be patient

for my ideas which will take a

long time to develop. I also

need to be creative enough to

have good ideas.

MIKE: What experience will be

most useful to you?

LI RU: I think technology and

engineering projects. I hope

to work in a factory in my

holidays.

MIKE: What kind of person makes a

good inventor?

LI RU: I think someone who is happy to

persevere at something and

learns from his mistakes.

MIKE: Thank you. I think designing

robots sounds fun.

Robert Briggs is very interested in

biology and especially in the study of

plants. Today he is telling his friend

Zhang Wei some exciting news.

Before you listen to the tape discuss

with your partner how you would find

out the name of a flower.

Listening (P41)

New words in the listening

passage:

species ( 种类 ) ， parrot ( 鹦鹉 ) ， blackbird ( 乌鸦 )

1. Which of the following statements describes

what this listening passage is about? Give your

reasons.

A. This is about a man who wants to name

a flower.

B. This is about a man who finds a flower

and wants to own it.

C. This is about a man who finds a flower

and wants to know if it is a new species of

flower.

It does not give enough information.

B is inaccurate.

Listen to the tape again and complete

the following passage.

To find the name of an unknown

flower first you should ask your ________

teacher to help you. He /She will look in a

special _____written by Carl Linnaeus.

biology

book

He lived in ______ from ____ to _____ .

He was very important because he

solved a ______ problem for biology.

Sweden 1707 1778

serious

1. If Robert Briggs finds the flower in the book, what does that mean?

It means that his flower has already been identified and has a name.

2. How would he know if his lily is a new species?

He would know by checking his lily against other lilies in the specialist book. If his lily is different it will be a new species.

Listen to the tape a third time and answer these questions.

3. Why do plants all have two names? All plants have two names just like

people. The first is the group of flowers they belong to and is like the family name. the second is the kind fo flower within that group and is like a given/personal name.

4. What was the serious problem for biology that Linnaeus solved?

Before Linnaeus there was no way of finding out whether a plant was new or not. This caused problems because different scientists claimed that they had found and named flowers first. After he organized his system it was easy to discover whether a plant was new or not and so who had the right to name it.

NAMING A FLOWER

Robert Briggs is talking to Zhang Wei

about a new kind of lily he has found.

Listening text

ZW : Hello Robert. What’s that book

you’re carrying?

RB : A book that helps you identify a

flower.

ZW: I see. Why do you want that?

RB: Well, I’ve found this lily. It looks

different to me. So I want to find

out if it’s new or not. Our biology

teacher told me that if it’s already

known, I’d find it in this book.

ZW: Wow! So you think you may have

found a new lily?

RB: I hope so, but I have to do some

research first to find out for sure.

ZW: What happens if it’s in the book?

RB: It means that somebody else has

found it and named it. Then I’ll know

its biological name.

ZW: What do you mean by the

biological name?

RB: Actually like us a flower has two

names. The first is the group of flowers

it belongs to- like a family name. A

rose is one such group.

The second is the kind of flower- like a

given name. ti may describe what the rose

looks like; for example, the color of an

autumn sunset. Together you get the

flower’s name, which is Rose Autumn

Sunset.

ZW: Gosh! Who made that system?

RB: A great scientist called Carl

Linnaeus. He lived in Sweden form 1707

to 1778 .

ZW: So long ago!

RB: Yes, and he solved a very serious

problem for biology.

ZW: What was that?

RB: Before him nobody could tell if a plant

was new, as there was no way of checking.

There’re so many plants, you see!

ZW: Yes, I appreciate that! So his

system is still used??

RB: Indeed it is. If my flower isn’t in

this book, I’ll know that I’ve found a

new kind of lily.

ZW: That’s great! Can I come and help

you? This research sound fun.

RB: Yes, and if I’m lucky….(fading out)

ZW: I see. So if your flower is new it

will be called "lily, Robert" will

it?

RB: Yes, it will --- if I'm very lucky.

ZW: Well, I hope you're successful.

Goodbye.

RB: Goodbye.

What was the problem of the city of

Konigsberg?

It had a river running through it. The centre of

Konigsberg is an island and as it passes the

island the river breaks into two parts. Seven

bridges were built so that the people of the city

could get from one part to another. The people

wondered if you could walk around the city so

that you would cross each bridge only once.

A MATHEMATICIAN'S PROBLEM

John Smith is talking to Zhao Yang

about a mathematician who interests him.

Listening text

Part I

JS: Did you know that we have been

studying Euler in maths?

ZY: Who is he? I’ve never heard of

him.

JS: Well, he was a famous

mathematician in the eighteenth

century. He revised

all the pure mathematics that was

known in his day.

ZY: That probably wasn't very much.

JS: You're wrong there. He wrote

more than any other

mathematician before or since.

ZY: Really! Well, what did he do?

JS: He introduced a lot of symbols into mathematics such as pi (Л) and the terms sine and cosine.

ZY: Wow!

JS: And he did half of this work

when he was blind

ZY: How did he do that?

JS: He told his ideas to someone else who wrote them down.

Part 2

ZY: What were his achievements?JS: He did introduce a new branch of mathematics called topology. It helps you understand things by usingdiagrams. The subway map is a good example. It doesn’t tell you distances but it shows how stations connect together.

ZY: How did he start topology?

JS: Well, in 1735 he was inspired by a

problem in the city of Konigsberg

where he lived. Look at the map in

your book.

Konigsberg had a river running

through it. The centre is an island. As

the river passes the island, it breaks into

two parts. Seven bridges were built over

the river. Euler wondered if you could

walk around the city so that you cross

each bridge only once.

ZY: Let me try that. It sounds quite

simple to me.

JS: Try, but it’s not as easy as it looks.
