四、单项选择
1. B. 空格处需要填入谓语动词，排除C；根据句意，警察搜索他的目的是看他是否带枪了，用“search sb.”表示“搜某人的身”。
2. D. 从答语中可以看出，说话人在抱怨相关部门应该采取措施防止火灾发生，而从第一个人的话中可知火灾已经发生过了，表示“本来应该做，却没有做”，用should have done。
3. B. “you had been thinking highly of”是定语从句，修饰The employee，省略的that或者whom代替the employee在定语从句中作宾语，与后面的动词没有关系。proved是主句的谓语，表示“证明是……”，是系动词，与后面的形容词一起表示状态，不用被动语态。句意：你一直评价很高的那个雇员后来证明是不诚实的。
4. A. 本题考查倒装句。由于but后的句子由半否定副词seldom居于句首，用部分倒装形式，将助动词have提前。
5. A. 部分“be of +名词” 相当于“be +形容词”的用法。
6. C. belong to是动词短语，并且不用进行时态和被动语态。答语中从后句可知，连汤姆这样的好学生都没有及格，说明题难了，因此第一空选Yes (，it’s difficult)。
7. C. 本题要特别注意辨别：in turn 转而，反过来，依次；in return 作为回报。根据句意，in turn更为恰当。
8. C. 句意为“张先生被选为会议主席”，用被动形式。
9. C. 本题考查情态动词表示推测的用法，用“can’t/ couldn’t have done”形式。
10. C. 根据句意，空白处指在地震中“成功逃生”的人，用survive表达此意。
11. C. 根据句意，“青少年不应当被从学校中清除，尽管……”，remove表达此意。
12. C. 句意为“要么是无意，要么是有意，他到得太晚，没法给我们帮忙”。by design为“有意为之”的意思。
13. A. serve as意为“用作，充当”，不用于被动语态。
14. B. in return意为“回报”；C项意为“偿还”，D项意为“归还”，不符合句意。
15. B. 句意为“在沙漠中他们从不同方向去找水”。in search of 寻找，搜寻。
16. C. 本题用needn’t have done表示对所做事情的后悔，“本没必要……”。
17. C. 对确定的情况“没有怀疑”，应该用that引导从句陈述事实。
18. A. 根据句意，游客们“感到吃惊”用amazing；风景“令人吃惊”用amazing。
