跪求虚拟语气的全部情况

Question

如题所述

Answer 1

虚拟语气
注意：条件句分两种，真实条件句和虚拟条件句。只有在虚拟（非真实）条件句中，才用虚拟语气，而在真实条件句中，要用陈述语气。
构成 条件从句 主句
时态 If＋一般现在时 主语＋shall/will+动词原形
例句 If he comes, he will take us to the zoo.

1） If it is sunny tomorrow , we’ll go to the zoo.
2）If I were you , I would go at once.
3). He doesn’t know if he should bring a present.（宾语从句，if表示是否）
拟语气表示和现实的事实相反时，从句用一般过时。
主句用 “should/would/could/ might +动词原形。
句型 ： 条件从句 一般过去时
主句 should( would) +动词原形
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in
知识点2.If I were you , I’d wear a shirt and tie.
表示于过去事实相反的假设。
句型： 条件从句 过去完成时
主句 should(would) have+ 过去分词
Eg. If my lawyer had been here last Saturday, he would have prevented me from going.
表示对将来的假想
句型： 条件从句 一般过去时 were+ 不定式 should + 动词原形
主句 should+ 动词原形 would + 动词原形
Eg. If you succeeded, everything would be all right.
If you should succeed, everything would be all right.
If you were to succeed, everything would be all right
