If I ________ it with my own eyes, I wouldn’t have believed it. A. didn’t see B. weren’t seeing C. wouldn’t see D. hadn’t seen 【答案】D。句意，如果我不是亲眼看见的，我不会相信它的。从句中 wouldn’t have believed 判断出是与 过去反事实，所以 if 从句应该用 had done 的形式。 2. ---The zookeeper was really annoyed with me. ---How could he have been if you ________ stones at the animals? A. didn’t throw B. don’t throw C. hadn’t throw D. haven’t throw 【答案】C。句意，动物园管理员真的恼怒我了。如果你没有向动物们扔石头，他怎么会这样呢？从主句 用 could have been 判断出是与过去反事实，所以 if 从句用 had done 的形式。 3.

A. would be B. wouldn’t be C. would have been D. wouldn’t have been 【答案】B。句意，那时如果你听从了我的建议，你现在就不会有麻烦了。由主句中 now 判断主句是与现 在反事实，所以用 would do 的形式，再根据翻译确定用否定。 3. 省略 If 的虚拟语气 如果虚拟条件句的谓语部分有 were, had 和 should 时，可省略 if，把 were，had 和 should 放到从句主 语前面。 If you were in my position, you would do the same. = ________ ________ in my position, you would do the same.

He was not present, otherwise, he _______ us. A. would have helped B. would help C. had helped D. helped 【答案】A。句意，他现在不在，否则，他就会帮助我们了。Otherwise 是含蓄条件句的标志，由上句 was 判断出是过去的事，所以 otherwise 相当于 if he had been present, 是一个与过去反事实的虚拟条件句，考 的是虚拟的主句，与过去反事实要用 would have done 的形式。 二、虚拟语气在 wish 后的宾语从句中的运用 1. 动词 wish 后的宾语从句中，谓语动词须用虚拟语气，表示与事实相反或不大可能实现的愿望。通常有 三种形式： ① 表示与现在愿望相反，宾语从句的谓语用______________________。 【答案】一般过去时 I wish I wasn’t going to Paris.
