If I had time, I would / could help you.2. If I had the chance, I would / might spend my holiday in France.3. If you had told me earlier, I would / should not have got into trouble.小结：would表示_，could表示_，might表示_，should表示_。当堂检测请用括号中所给动词的适当形式填空。1. If he _ (be) here now, he _ (be) able to help us.2. I _ (talk) to him about it if he _ (come) tomorrow.3. If you _ (join) the chat room ten minutes ago, you _ (know) what we were talking about.小结：判断是真实条件句还是非真实条件句。看假设的条件是否能够实现，能够实现的是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用_语气。探究三、条件状语的倒装1. 请观察下列句子。(1) If you were to take the train, you would get there much sooner.= Were you to take the train, you would get there much sooner. (2) If it should be fine tomorrow, we would go for an outing.= Should it be fine tomorrow, we would go for an outing.(3) If I had worked hard, I would have succeeded=Had I worked hard, I would have succeeded.结论：在书面语中，如果虚拟条件句中有were, had或should时，可以把if省略，而将were, had, should 提到主语的前面，构成_，即Were / Should / Had +主+其他。 If time were to go back, I would work double hard.=_ time _ go back, I would work double hard.If I had time now, I would go to the library. Had I time now, (）注意：在省略句型中，只有had done 的had 才能省略，实义动词had 不能省。2. 【即时巩固】选择(1) _ more careful, his bus would not have knocked into the tree.A. If the driver were B. Had the driver been C.

(副词)He telephoned to inform me of your birthday, or I would have known nothing about it. (连词)A man who stopped drinking water would be dead in about seven days. （定语从句）I might have given you more help, but I was too busy. (连词)Everything taken into consideration, they would have raiser their output quickly. (独立主格结构)小结：上述各句均无明确的if条件状语从句，但均用了虚拟语气，我们可称它们为_条件句。当堂检测 请用括号中所给动词的适当形式填空。1. Im too busy now, or I _ (go) there with you.= If I _ (not be) busy now, I _ (go) there with you.2. With more money, I _ (help) more people.= If I _ (have) more money, I _ (help) more people.3.
