Step 2.Fast-reading
Read the second passage and answer the following question:
What was Einstein’s discovery in the text?
Light becomes bent when passing the stars.
Step 3.Detailed-reading
Now get the students to read the second text more carefully, and do the judgment on P75 with the class. The following statements are mainly based on the second text. Tell me if they are true or false.
(F) 1.Einstein proved that light traveled through space in a straight line.
(T) 2.Einstein’s discovery was completely new at that time.
(T) 3.Many of the scientists did not accept Einstein's scientific ideas at first.
(F) 4.Einstein had to stop his research because he couldn't prove his ideas.
(T) 5.By 1919 he quickly became world-famous because the scientists who had been watching the stars supported his work.
(F) 6.He took Swiss nationality in 1909 in order to study there.

(F) 8.Germany was ruled by Hitler during the First World War.
(F) 9.Einstein and his family left Europe for the USA in 1933 because he was afraid of being killed in the war.
Step 4.Language points of the text:
1. Before Einstein, scientists believed that light travelled through space in a straight line.在爱因斯坦之前，科学家们相信光线是以直线通过太空的。
1) travel, quarrel的过去式、过去分词以及现在分词既可双写“l”，也可单写“l”。而control, level, signal的过去式、过去分词以及现在分词必须双写。
2) 在space前一般不加冠词，如:
in space在太空 in outer space在太空
其他有关天体方面的名词前的冠词大致如下:
in the universe 在宇宙中 in heaven 在天堂 in the sky 在天空中
in nature 在大自然里 on the earth/on earth, on Mars 在地球或火星上
2. But Einstein was able to prove that light coming from the stars was bent as it passed the sun. 但是爱因斯坦成功地证明了从恒星上传来的光线在经过太阳时被弯曲了。
1) be able to do sth. 的过去时was/were able to do sth. 常常表示“成功地做了某事”之意，相当于managed to do sth./succeeded in doing sth./did sth. successfully. 如：
The pilot was able to land his plane safely in the end. 那个飞行员最终成功地安全着陆了。
We were able to beat Chicago Bulls in the second half. 我们在下半场打败了芝家哥公牛队。
2) 动词prove的结构比较多，有prove sth., prove to be, prove sth. to be, prove+adj., prove+that 名词性从句等等。如：
Einstein's theory proved (to be) correct. 爱因斯坦的理论证明是正确的。
Galileo proved that the earth moves around the sun like the other planets.
伽利略证明地球像其他行星一样围绕太阳转。
Can you prove (yourself) to be fit for the position? 你能证明自己胜任这个职位吗?
We need to prove the will before it can take effect. 遗嘱生效之前我们需要证实它。
名词：proof［C］［U］证据
Is there any proof that she was on the spot when the murder took place?
有证据证明谋杀发生时她在谋杀现场吗?
3. As a result, it appeared to scientists on earth that the stars had moved.
结果，在地球上的科学家看来，似乎恒星移动了。
在本句中，appear不是不及物动词“出现”，而是系动词“似乎”、“看上去”，相当于seem,其结构也与seem相近，如：
Why do you appear/seem (to be) so pale? 你为什么显得如此苍白?
There appear/seem to have be
