统考例题（重点掌握）
1. Jean did not have time to go to the concert last night because she was busy ______ for her examination.
A. to prepare B. to be prepared C. preparing D. being prepared
解析：busy的用法是be busy with sth.和be busy doing sth.，本题中可以说she was busy with her examination或she was busy preparing for her examination，所以选择C。
2. The computer doesn’t work well, so something ________ wrong.
A. can have gone B. should have gone
C. must have gone D. ought to have gone
解析：此题的考点是情态动词must与have done的搭配。这一结构表示对过去情况有把握的猜测，具有“肯定、一定”的意思，所以选择C。
3. Although Mary is satisfied with her success, she wonders _____ will happen to her private life.
A. how B. who C. what D. that
解析：此题的考点是宾语从句的连接词。wonder后接宾语从句，该宾语从句由what来引导，所以选择C。
4. If the whole program _______ beforehand, a great deal of time and money would have been lost.
A. was not planned B. were not planned
C. would not be planned D. had not been planned
解析：本题考查虚拟语气。与过去事实相反的假设，句型为：If +主语+ had +动词过去分词，主语+would/could/should/might + have + 动词过去分词。例如：If I had known your address, I would have written to you.（假如我知道你的地址，我早就写信给你了。）所以选择D。
5. I am very greatly to you for what you’ve given me and _______ you have done for me.
A. which B. that C. all what D. all that
解析：此题的考点定语从句关系代词。all后面的定语从句的引导词只能是that，不能用其它。所以选择D。
