1.（2010高考英语天津卷）John went to the hospital alone. If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told
【答案】D 【解析】主从句都是对过去发生事实的一种意愿表达， 从句采用have done的结构，故选D。
【答案】 D 【解析】表示与过去事实相反的假设，故主句用 would/could/might/should+have done，即D项 正确。
注意以下问题：
1. 错综时间虚拟条件句 2. (if省略) 倒装虚拟条件句 3. 含蓄条件句
3、错综时间虚拟句（混合虚拟条件句)
通常情况下,在非真实条件句中主句和从句的 谓语动词所指时间是一致的,但有时也可能指 不同的时间,这时要根据上下文的意思采用不 同的谓语动词形式。虚拟条件句和主句动作如 发生的时间不一致，主句和从句的谓语要根据 各自所指的不同时间选用适当的虚拟语气形式， 这种句子叫做错综时间条件句。

• If he had not taken my advice, he wouldn't do it much better like this. 如果他不听取我的建议，他就不会干得这样好。
• If it should rain tomorrow, the sports meeting would be put off.
= Should it rain tomorrow, the sports meeting would be put off.
• If you had come a little earlier, you would have seen her.
