英语语法+大学英语语法总结(1)

关于英语那些你不知道的事都在这里
I not to do., 而不能说Weren't I to do.
混合条件句
主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据表示的时间进行调整。
If you had asked him yesterday, you would know what to do now.
（从句与过去事实相反，主句与现在事实相反。）


If it had rained last night (过去), it would be very cold today (现在).
Wish 句型表达“但愿…，要是…多好”的语气
表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为：
真实状况wish后
从句动作先于主句动词动作现在时过去时
（be的过去式为were）
从句动作与主句动作同时发生过去时过去完成时
（had + 过去分词）
将来不大可能实现的愿望将来时would/could +
动词原形
I wish I were as tall as you. 我希望和你一样高。
He wished he hadn't said that. 他希望他没讲那样的话。
I wish it would rain tomorrow. 我希望明天下雨就好了。
Wish to do表达法
Wish sb / sth to do
I wish to see the manager. = I want to see the manager.
I wish the manager to be informed at once. (= I want the manager to be informed at once.)
在强制性语气的宾语从句中的运用


即表示建议、命令、劝告、决心等主观色彩的动词+ that + (should) + 动词原形，其中should 经常被省略。这类动词包括：
suggest, propose, recommend, demand, order, command, desire, require, insist, advise, decree (发布命令；下令), determine, prefer, stipulate, move(动议，规定)，direct(命令)，maintain(坚持)，decide，ask
I suggest that you (should) not be late again next time.
I prefer that you ( should ) not do that. 我认为你还是别干那件事的好。
注意一：
以上动词转化为名词(如：suggestion, proposal, demand, order, command, advice, desire, requirement, request, agreement, determination, preference , resolution, indication 等)后接同位语从句或表语从句时，从句要求用虚拟语气，其谓语部分用“(should)+ 动词原形” (should可省略)。
