5. It was twelve o'clock_______they finished the work.

A. since　　　 B. which　　　 C. that　　　　 D. when

答案：D　 指导：此题易受强调句型思维定势影响而选C将其还原，则变成They finished the work twelve o'clock．显然twelveo'clock前省了介词at．因此可判定该题后面部分为定语从句，关系副词when在从句中作状语，it指代时间，不属于强调句型中的it.

4. In the office I never seem to have time until 5 .. 30p. m.,_______many people have gone home.

3. I shall never forget those years I_______ lived the country　 with the farmers, _______has a great effect on my life.

　　　 A. that; which　　　　　　　 B. when; which

C. which; that　　　　　　　 D. when; who

答案：B　 指导：第一填when，when引导一个定语从句，修饰前面的those years在从句中作状语(＝inwhich)；第二个空用which，which在此处指代前面整个句子并在从句中作主语。　 句意为：我永远都不会忘记在乡下和农民一起度过的那些岁月。这里指“度过岁月”这件事对我一生影响极大。

2. Mother bought me a dictionary on my birthday,_______made me very happy.

A. what　　 B. that　　　　 C. who　　　 D. which

5.Do you still remember the chicken farm _______ we visited three months ago?

A. where　　 B. when　　 C. that　　　 D. what

答案：D　 指导：whoever在从句中作主语，相当于anyonewho，此题易误选C。好像可以用whomever作to的宾语，事实上，引导词的使用主要取决于它在从句中的语法作用。如：I'd like to give this rose to whomever I met on Feb．14．whomever作met的宾语。

4.On stepping into his room he was astonished to find the　 floor covered with_______ looked like tiny insects.

1 Roses need special care_______ they can live through winter.

A. because　 B. so that　　 C. even if　　 D. as

答案：B　 指导：句意，玫瑰需要特殊的呵护，这样它们才能度过寒 冬。so that引导目的状语从句。其他三项表示的逻辑关系 显然有悖常理。用because和as这样来描述原因才符合逻辑：Rose need special care in winter because／aS they can't　 live throngh without any care．玫瑰在冬天需要呵护，因为如果不加呵护它们就过不了寒冬。Even as即使，由它连接起来的题干句有悖于一般的认识。

　　　 A. what it takes　　　　　 B. what takes it
