Unit 2
Listening
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?
When Qian Xuesen returned to China
he set up a Space Institute to begin
training people in how to design and
build rockets.

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.
