2、ing to her friend Steve Smith about Qian Xuesen and his work as a rocket scientist.Great ScientistsQ 1:What did Qian Xuesen study first?Qian Xuesen first studied to be an engineer.Q 2:What experience did he get in America that was very useful for China?In America he began to work on space rockets so
3、 that he was able to develop a space programme when he came back to China.Q 3:What was Qian Xuesens achievement when he returned to China from America?When he returned to China he set up a space institute to begin training people in how to design and build rockets.Great ScientistsChinas achievement
4、in space Steve Smiths ambitions1、Chinese astronauts in space2、Chinese satellites in space1、become a rocket astronaut2、be the first to land on Mars Qian Xuesen is an astronomer who specializes in rocket.He first studied at university to be an engineer.Later he went to America and started work on rock
5、et.When he comes back to China he begins the first institute in the country to design and build rocket to go into space.Now China has sent satellites into space.In the future,Chinese astronaut will land on Mars as well.Listen again and summarizeNicolaus Copernicus born:in Poland in 1473in Poland in

12、 the centre of the solar system with the planets going round it and only the moon still going round the earth.He also suggested that the earth was spinning as it went round it and this explain changes in the movement of the planets and in the brightness of the stars.He published it as he lay dying i
13、n 1543 (6)Why do people think that there is a direct link between his ideas and the work of Isaac Newton,Albert Einstein and Stephen Hawking?Because his theory is now the base on which all our ideas of the universe are built.His theory replaced the Christian idea of gravity which said things fell to
14、 earth because God created the earth as the centre of the universe,He showed this was obviously wrong.If you were Nicolaus Copernicus,would you have hidden your theory for so many years?As a scientist,one should be brave.But Copernicus was afraid of being attacked by the Christian Church.So he had h
15、idden his theory for so many years.What do you think of this?Agree:1.He was cautious.if had published,he would just as Bruno who was because his theory was against.2.Every time when a new idea,there are always.Its normal.Scientists should to spread their truth.3.It made no sense for him to in a hurr
