二、重難點句子

1. Scientists, on the other hand, Hawking writes, know that their job is never finished and that even the best theory can turn out to be wrong.

  霍金寫道,從另一個方面說,科學家知道他們的工作永遠是無止境的,即使是最好的理論也可能被證明是錯誤的。

(1)on the other hand 與Hawking writes 均為本句的插語,原句應為:

   Hawking writes scientists, on the other hand, know that…, scientists know that…是writes 的整個賓語主句,that their job… 則又是賓語從句中的謂語動詞 knows 所引導的另一個賓語從句。

(2)…and that even the best theory can turn out to be wrong 是writes 引導的賓語從句中謂語動詞know引導的第二個并列賓語從句。在英語中,賓語從句的引導詞that可以被省略,但如果一個動詞引導兩個以上并列的賓語從句時,第二個及以后的賓語從句中的that不可省略。例如:

   He said that he would come back soon and that he would continue to learn drawing.

   他說他馬上就會回來的,而且會繼續學習繪畫的。

(3)turn out“結果(是);證明(是);原來(是)”(to happen to be in the end)往往指結果與所預想的或表面上的不一致。例如:

   His answer turned out to be wrong.

   他的答案被證明是錯誤的。(turn out to be…)

   The party turned out a success.

   聚會很成功。(turn out sth)

   He turned out to live in Hastings.

   原來他住在黑斯廷斯。(turn out to do)

   It's turned out nice and sunny again.

   (天氣)終于又是陽光普照了。

2. By asking why, how and what if, curious mind find new ideas and solutions.

通過不停地問自已為什么,如何運作和盤根究底的假設,這個求知的人終于找到新的主意及方法了。

what if倘使…將會怎樣;即使…又有什么要緊。

例如:

What if we move the picture over here? Do you think it'll look better?

把畫移到這兒會怎樣?你看會不會好看一點?

What if you should fail?

假如你失敗了,該怎么辦呢?

What if he fails?

如果他失敗又有什么關系?
