Qian XueSen
(1911-2009)
Do you know this old man?
Listening and speaking (P 6)
Father of China’s Aerospace & King of Rockets
Qian Xuesen, a native of Hangzhou, Zhejiang Province, went to the United States to study in 1935. In 1955 he returned to China, and in 1958 he joined the Communist Party.
How much do you know about Qian Xuesen?
Qian Xuesen is one of the best-known
scientists in China. His work has been very
important for the development of China.
Qian played a leading role in the research,
manufacture and testing of carrier rockets,
guided missiles and satellites, thus making
outstanding contributions to the development
of China’s aerospace industry.
Look at the pictures and predict the
content of the listening. (P 6)
Shenzhou-V
It’s about the role of Qian Xuesen in the development of space technology in China.
Listen to Part 1 and 2 of the tape for the first time and write down the main idea.
1. What did Qian study first?
Listen to Part 1 again and answer these
questions.
2. What experience did he get in America that was useful for China?
In America he began to work on space rockets so that he was able to develop a space program when he came back to China.
3. What was Qian Xuesen’s main achievement when he returned to China?
Qian Xuesen first studied to be an engineer.
When Qian Xuesen returned to China, he set up a Space Institute to begin training people in how to design and build rockets.
Listen to Part 2 and fill in the chart below.

In groups discuss a scientific job you might choose in the future.
What is its necessary qualifications?
Does it need any experience?
What is it expected?
How do you feel about it?
Sample conversation
S1: What do you want to do when you
grow up?
S2: I want to build robots. I will have to do
a physics and mathematics degree in
China. 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.
S1: Why will personality be needed for
that job?
S2: They have a lot of uses: for example,
in making cars on a production line
or doing other repetitive jobs.
S1: What personality will be needed for
that job?
S2: I think I need to be patient for my ideas
will take a long time to develop. I also
need to be creative enough to have good
ideas.
S1: What experience will be most useful to
you?
S2: I think technology and engineering
projects. I hope to work in a factory in
my holidays.
S1: What kind of person makes a good
inventor?
S2: I think someone who is happy to
persevere at something and learns
from his mistakes.
S1: Thank you. I think designing robots
sounds fun.
Listening (P 41)
Carl Linnaeus (1707 – 1778) is known as the father of modern taxonomy (分类学), and is also considered as one of the fathers of modern ecology (生态学).
Robert Briggs is telling his friend Zhang Wei some exciting news.
What is the listening passage about?
This is about a man who finds a flower and wants to know if it is a new species of flower.
Listen again and answer the questions.
If Robert Briggs finds the flower in the book, what does that mean?
How would he know if his lily is a new species?
It means that his flower has already been identified and has a name.
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 of flower within that group and is like a given / personal name.
Before Linnaeus here 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.
4. What was the serious problems for biology
that Linnaeus solved?

1. Introduced many new symbols into maths
2. Wrote more books than anyone before or since
3. Discovered a new branch of mathematics
Euler’s new branch of mathematics
Why Euler is considered to be a great mathematician?
数学史上公认的4名最伟大的数学家分别是：阿基米德、牛顿、欧拉和高斯。阿基米德有“翘起地球”的豪言壮语，牛顿因为苹果闻名世界，高斯少年时就显露出计算天赋，唯独欧拉没有戏剧性的故事让人印象深刻。然而，几乎每一个数学领域都可以看到欧拉的名字。欧拉还是数学史上最多产的数学家，他一生写下886种书籍论文，平均每年写出800多页，彼得堡科学院为了整理他的著作，足足忙碌了47年。
