Before we begin to listen to it, 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.

It is about the role of Qian Xuesen in the
development of space technology in
China.
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.
Listen to part 1 again and answer the questions

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.

China’s achievements
in space Steve smith’s ambitions
Listen to Part 2 and fill in the chart below.
1. China astronauts in space.
2. Chinese satellites in space
1. Become a rocket scientist
2. Be the first to land on Mars and put Qian Xuesen’s pitture there
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: What 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
Listen to the tape for the third time and answer these questions.
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.
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.
pure(纯的), symbol(符号),
Л(圆周率); sine(正弦),
cosine(余弦), topology(拓扑学)
angle(角), diagram(图表)
Listening Task (P44)

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.
