【推荐】高二英语选修7 【英语】北师大版 语法·剖析·活用(Unit 21 HUMAN BIOLOGY)
语法·剖析·活用虚拟语气条件从句主句主语+would+动词原形与现在事实相反If+主语+动词过去式(be的过去式一律用were)与过去事实相反If+主语+had动词过去分词主语+ would+have+动词过去分词主语+would (should)+动词原形与将来事实相反were+不定式should +动词原形虚拟语气混合条件句在虚拟语气中，主句与从句的动作发生在不同的时间，这时主、从句谓语动词的形式因时间的不同而不同，这叫做混合条件句，也叫做错综时间条件句。
这样的句子不仅仅是时间的不同，更重要的是事实和假设的混合。
这种虚拟情况的动词形式应根据实际情况灵活使用。
如：If you had asked him yesterday, you would know what to do now.如果你昨天问他，你现在会知道做什么。
If you hadn’t watched TV that late last night, you wouldn’t be so sleepy.如果你昨天晚上看电视不那么晚，你现在不会这么困倦。
You would be much better now if you had taken my advice.假如你接受了我的意见，你现在就会好多了。
Had Mr. Li received two more votes in the last election, he would be our chairman now.如果李先生在最后的竞选中，多得两票，他现在会成为我们的主席。
虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。
If it had rained last night , it would be very cold today.＝Had it rained last night, it would be very cold today.如果昨天下雨了，今天会很冷的。

The best exercise is one that you enjoy and will do. But otherwise. . . it’s probably running. To avoid knee pain, you can run on soft surfaces, do exercises to strengthen your leg muscles, avoid hills and get good running shoes. Running is cheap, easy and it’s always energetic. If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give it a try.
