　　【答案】B
　　. There is a good social life in the village, and I wish I _______ a second chance to become more involved.
　　A. had B. will haveC. would have had D. have had
　　【答案】A
　　【解析】考查虚拟语气。句意：在这个村里有很好的社交生活，并且我希望我再有机会去更多的参与。本题考查wish引导的宾语从句，表示与现在事实相反的愿望，所以从句用一般过去时。故选A。

　　【答案】D
　　In today’s information age, the loss of data _________ cause serious problems for a company.
　　A. need B. should C. can D. must
　　【答案】C
　　【解析】考查情态动词。句意：在今天的信息时代，数据的丢失有时会对一个公司造成严重的问题。数据丢失造成严重问题是客观上会发生的情况，即“客观可能性”，故该空应用情态动词can。C选项正确。其余情态动词均没有该用法。need需要；should应该，竟然；must必须，肯定。
　　They might have found a better hotel if they _________ a few more kilometers.
　　A. drove B. would drive C. were to drive D. had driven
　　【答案】D
　　【解析】考查虚拟语气。句意：如果他们多开几公里的话，他们也许会找到一个更好的旅馆。由“they might have found a better hotel”可知，该句是表示对过去的虚拟。if ____ a few more kilometers是条件句部分，表示对过去的虚拟，条件句部分要用过去完成时态，故D选项正确。

　　A. had caught B. caught C. have caught D. would catch
