4. Why can’t you realize the part ________ they have played in our life?
A. which
B. on which
C. when
D. where
【解析】正确答案分别是D和A.一些词组和搭配被拆开后,句子的含义就变得难以理解。首先把拆开的词组复原是理解此类定语从句的关键。上述句子中包含以下词组:make use of, play a part (in)。
四、添加插入语或状语
5. The scientist has made another discovery, _______ I believe is of great importance.
A. that
B. /
C. which
D. why
【解析】应选择C.这类句子主要利用插入语或状语的添加来增加试题的难度。常见的插入语有:I think (suppose, expect, believe, imagine), in my opinion, to tell you the truth等。做这类题目时,最佳的办法是先删去插入语或状语,这样句子的主干部分就一目了然了。
