单项填空题解题技巧十法详解九：固定搭配法

 　英语句子中词语和词语之间有一定的"固定搭配"。主要包括短语介词，短语动词，冠词在固定搭配中的用法等。因此，如果我们熟悉这些固定搭配，就会很容易地选择正确答案。
　　25. For a long time they walked without saying ______ word. Jim was
　　the first to break_____ silence
　　A. the; a B. a; the; C. a;不填 D. the;不填该题看似考查冠词，实际上是考查冠词在固定搭配中的用法。这里say a word表示"说话"；break the silence表示"打破沉默"。故正确答案为B.
　　26. Everyone in the town knew him so we had no difficulty _____ his house.
　　A. find B. found C. finding D. to find
　　根据固定搭配动词短语have difficulty in doing sth. 其中in可以省略。故正确答案为C.
　　27. He joined us ______ a new way of increasing production.
　　A. in search of B. in search for
　　C. in the search of D. in searching of
　　此题考查介词短语的用法。与此相关的正确短语有：in search of in one's search for in the search for. 故正确答案为A.
