17、 he had hidden his theory for so many years. What do you think of this? Agree1.

I hope you will publish it for se

23、veral 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 centre 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 observatio

24、ns 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, Zhang Hua1.Surf the Internet and get more information about Copernicus. http:/ 2.Finish your “reading task” and “writing task” after class.3.Revise the whole unit.4.Finish “Summing up”.
