Fill in the blanks with some proper words

◆ 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 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, he must have the courage to publish his findings. No matter how people oppose them, time will show if your ideas are right or wrong.

only if 表示“只有……(才);只有在……的时候,唯一 的条件是……”的意思。 I told him he would succeed only if he tried hard. 我告诉他,只有努力才能成功。

当only if 引导的状语从句置于主句之前时,其后的主句
要用倒装语序。 Only if a teacher has given permission is a student allowed to enter this room. 只有得到教师的允许,学生才可以进这间屋。

only if / if only only if 意为“只要”,可视为 if 的加强说法,如 放在句首,其后的主句要用倒装语序。 Only if you eat the correct foods will you be able to keep fit and stay healthy. if only表示“但愿”,“要是……就好了”,此 时多与虚拟语气连用。 It's a good plan, if only we could carry it out.

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

Persuasive writing (Please refer to P8 Learning Tip)
Now writing a short letter asking Copernicus to publish his ideas so everyone can read them. First you need to collect your ideas. For example:

?He believes his new theory is true.
?There are problems with the present theory. ?He has done many years of observations to prove his new theory is true. ?Science can’t develop unless people publish their ideas. ?Time will show if his theory is true or not.

Here is a plan:
Beginning: Tell Copernicus who you are and why you want him to publish his ideas.
Paragraph 1: Reason 1 and evidence. Paragraph 2: Reason 2 and evidence.

Summing up: Ask him to think again about publishing his ideas.

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
