2.He insisted that we (should ) tell him the news.

由于这些动词本身隐含说话者的主观意见，认为某事应该或不应该怎样，这些词语后面的“that”从句应用虚拟语气，且均以“should+动词原形”表示这种语气，但事实上“should”常被省略，故此从句中谓语动词用原形，常用的此类动词有：

表示“要求”的：ask, desire, request, demand, require, beg

表示“提议、劝告、建议”的：move, prpose, suggest, recommend, advise, vote

表示“决定、命令”的：decide, order

表示“主张”的：maintain, urge

表示“同意、坚持”的：consent, insist

例如：

1.The doctor suggested that he (should) try to lose his weight.

2. 如果that 从句中用would , 一般表示对现状不满或希望未来有所改变或请求

I wish he would answer my letter.

I wish prices would come down.

I wish you would help me.

I wish you would stop asking silly questions.

1.如果将wish改为过去式wished, 其后that 从句中的动词形式不变。例如：

I wished I hadn't spent so much money.

我要是那时没有花掉那么多钱就好了。

5. He will wish we would join him the following week.(would + join)

(只是希望我们和他在一起，实际上还没在一起)

四)、注意：

4. I wish she would change her mind.(would + change)

我希望她会改变主意。(呵呵，女孩子可没那么容易就改变主意喔)

3. You wished she would arrive the next day.(would + arrive)

你希望她第二天会到。(事实上她还没到)

2. I wish you would be quiet.(would + be)

我希望你安静一些。(事实上那家伙还在吵着呢)

1. I wish it would stop raining.(虚拟动词would+动词原形stop)

我希望雨能停止。(事实上雨还在下着呢)

5. They will wish they had listened to us sooner.

(will wish,had + listened)(事实上并不如此)

例题分析：I wish I ______ longer this morning, but I had to get up and come to class.

A. could have slept 　B. slept　C. might have slept 　D. have slept

动词wish后面接从句，表达不可能实现或与事实相反的情况时，谓语动词要用虚拟语气，即用过去式(表示现在发生的动作)或过去完成式(表示过去发生的动作)。本题后半句谓语动词have用的是过去时had

to get up and come, 所以前面要用过去完成时表示过去发生的动作。所以, 选项A)could have slept是答案

三)、对将来情况的虚拟(表示将来的主观愿望)：

从句动词"would/should/could/might + 动词原形"(时间上较后)(请注意：主句和从句的主语不相同)。用wish表示对将来事情的愿望。例：
