高中英语 Unit 1 Great scientists Reading and Writing课件 新人教版必修5


Nicolaus Copernicus

born: in Poland in 1473 died : May 24, 1543

He was one of the first scientists to use mathematical observations to collect information. He believed the sun is the center of the universe and the earth and other planets went around it.

Nine Planets In the Solar System

Before Copernicus’

theory

Showing Copernicus’ theory

A diagram showing the solar system with the earth at its centre

A diagram showing the solar system with the sun at its centre

Read the text carefully, then answer these questions

(1)What did Copernicus believed is the centre of the solar system

The sun.
(2) What did the Christian Church

believe was the centre of the earth?

The earth. Which one is right?

(3) When did Copernicus complete his theory? (Para 3)
Between 1510 and 1514 he worked on it, gradually improving his theory until he felt it was complete.

? ( 4 ) After

how many years did he publish his new theory?

After 29years he published it as he lay dying.
? ( 5) why

did he publish it so late?

His theory was against God’s idea, and the powerful Christian Church
would have punished him if he put forward such an idea.

◆ As a scientist, one should be brave. But Copernicus was afraid of being attacked by the Christian Church. So he had hidden his theory for so many years. What do you think of this? Agree: 1.He was cautious. if he had published his ideas, he would have been killed just as Bruno who was burned to death because his theory was against the Christian Church. 2.Every time when a new idea appears, there are always rejections. It’s normal. Scientists should have patience to spread their truth. 3.It made no sense for him to publish his theory in a hurry.He was just cautious not coward. He should protect himself first.

Disagree: 1.Copernicus was very coward. He should speak out his discovery and let the world know the truth earlier. 2.Science can never advance unless people have the courage of their beliefs. 3.As a scientist, you must have the courage to publish your findings. No matter how people oppose them, time will show if your ideas are right or wrong.

? Write a short letter asking Copernicus to publish his ideas so everyone can read them.

One possible version:
Dear Nicolaus Copernicus,
I am a student studying astronomy and I would very much like to read your new theory about the solar system. I hope you will publish it for several reasons. I understand the problems with the present theory. The way the planets move is not what you would expect if the earth was the center of the universe. It is also odd that the brightness of some stars seems to change. So I agree with you that we need a new theory.

I know your observations have been very carefully carried out over many years. Now you must have the courage to publish them. Science can never advance unless people have the courage of their beliefs. I know you worry about what will happen if you publish your new theory. No matter how people oppose it, time will show if your ideas are right or wrong. So I hope you will feel you can publish your new theory.

Yours sincerely,
Lin Qi
