〖答案〗C

〖考点〗考查情态动词的区别。

〖解析〗will可用来表示 "意愿；客观必然性等"；would可表示 "意愿；过去常常（现

在也可能是那样的）"；should表示 "应该, 理应"；must表示 "必然；一定, 准是"。结合语境可知, 此处用should表示虚拟。句意为： "这本来应该是美丽的, 但是现在它被严重污染了。

5. ________ the morning train, he would not have been late for the meeting.

A. Did he catch B. should be catch C. has he caught D. Had he caught

【考点】考察省略和倒装以及虚拟语气

【答案】D

【解析】本题实际上是一个条件状语从句的虚拟语气，表示与过去事实相反。条件句中使用"过去完成式"，主句使用"情态动词+have done"；当条件句中的if省略的时候，要把had提前形成部分倒装。句义：如果他赶上了早班火车，他就不会开会迟到了。故D正确。
