題組29（as/it/what）

1. _____ is known to everybody, the moon travels round the earth once every month.（全國卷）

A. It   B. As   C. That   D. What   選B。

2. The air quality in the city, ____is shown in the report, has improved over the past two months. (2012,福建)

A. that   B. it   C. as   D. what

句意：正如報告中所寫的那樣，在過去的兩個月中，這座城市的空氣質(zhì)量提高了。

分析：把從句放在句首就很明白了:    is shown in the report, the air quality in the city has improved over the past two months. “正如在報告中所寫的那樣”，as指的是下文所提到的話。選C。

3. ____ in the regulations that you should not tell other people the password of your email account.（上海高考題）   A. What is required   B. What requires is   C. It is required   D. It requires  

句意：規(guī)則要求你不應(yīng)把你的電子郵件的密碼告訴別人。選C。

4. ____ was most important to her, she told me, was her family. (2008,山東).

A. It   B. This   C. What   D. As   

分析：what是主語從句的引導(dǎo)詞，其余都不是。選C。

5. Everyone knows that ____ is dangerous to play with fire，but ____ is difficult is to prevent children from playing with fire. (陷阱題).   A. it, it   B. what, what  C. it, what  D. what, it

分析：容易誤選A或B。其實(shí)，第一空填形式主語it，真正的主語是其后的不定式 to play with fire。第二空填 what，what is difficult 是主語從句（注意到what is difficult 后有is，若沒有這個is，則第二空也填it）。答案是C。
