3)The only thing _____ can be done is to stop them from going there.
A. which
B. that
C. what
D. who
解题思路:记住:定语从句中永远不可能出现what做连接词, 记住这句话对理解名词性从句会大有帮助; 既然先行词为thing(事情), 就不能用who连接;同时出现which和that,又没有,号,当然选B(the only thing只能用 that连接,不能用 which连接)。下面一题的思路是一样的:
4)All ______ is a continuous supply of the basic necessities of life.
A. which is needed
B. that is needed
C. what is needed
D. is needed
正确答案是:B 注意:all that = what, 不可能出现all what
5) Some of the roads have been flooded(淹没), ______ our journey more difficult.
A. it makes
B. they make
C. which makes
D. which make
解题思路:四个答题中有两个区分点:第一个区分点是:C、D都用了连接词which,而A、B没有用,根据逗号不能连接两个句子的原则,A、B肯定不对;第二个区分点是:C、D中,动词一个用单数形式makes,一个用复数形式,这里应选择C.为什么?非限制性定语从句中,除了说明先行的某个名词外,还可以说明整个句子的内容,此时动词用单数形式。全句意思:有的路已被洪水淹没,这使我们的旅行更加困难。which代表有的路已被洪水淹没这件事情。
