partly notes
1. 虚拟语气:
1)

2)wish/as if
1>表示与现在事实相反的愿望
构成:主语 + wish (that) + 从句主语 + 动词过去式 (be 一律用were)
例如:I wish I knew everything in the world.我希望我知道世界上所有的事。
2> 表示与过去事实相反的愿望
构成:主语 + wish (that) + 从句主语 + would/could + have + 过去分词或had + 过去分词
例如:I wish that you had come yesterday.我希望你昨天来过。
I wish that I could have gone with you last night.我希望我昨晚能和你一起去。
3> 表示将来不大可能实现的愿望
构成:主语 + wish (that) + 从句主语 + would/should/could/might + 原形动词
例如:I wish that he could try again.我希望他能再次尝试。
3)wish与hope接宾语从句的区别在于:hope表示一般可以实现的希望,宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。
1> We hope they will come. (We don’t know if they can come.)
2> We wish they could come. (We know they are not coming.)
4)if only 与 I wish一样,也用于表示与事实相反的愿望,其后所虚拟语气的时态与 wish后所接时态的情况相同:
If only she had had more courage! 她再勇敢一些就好了。
If only she would go with me! 她要是愿意和我一道去就好了!
*if only 通常独立使用,没有主句。
5)l would rather后句子用虚拟语气 只分现在和过去
在would rather, would sooner, would just as soon后的that从句中, 句子谓语习惯上要用虚拟语气, 表示"宁愿做什么" ,具体用法为:
①一般过去时表示现在或将来的愿望
I’d rather you went tomorrow (now). 我宁愿你明天(现在)去。
②用过去完成时表过去的愿望
I’d rather you hadn’t said it. 我真希望你没有这样说过。
