与现在事实相反,谓语用一般过去时态。例如：

I wish I had your brain.

与过去事实相反，谓语用过过去完成时态。例如：

How I wished I had studied then!

与将来事实相反，或不大可能实现的愿望，谓语用

would/could do。 例如：

How I wish that I would go to the moon some day.

(2)command,demand,insist,order,request,require,suggest等后面

的宾语从句，谓语用(should) do。总体掌握："要求干，应该

干，但还没干"，就是说动作还没有发生。因此insist"坚持事

实"、suggest"暗示"都不用虚拟语气。

Mother insists I get rid of the bad habit.

He insisted that he was a Party member and be sent to the

front.

注意：与此项有关的表语从句、同位语从句、主语从句等的谓

语同样用(should) do。例如：

My suggestion is that he do the exercises first.

这样的名词有：advice, idea, demand, order, plan, request,

suggestion等。

3.主语从句中的虚拟语气：谓语同样用(should) do。例如：

It is necessary (important) that a student (should) have good

manners.

It was a pity that you (should) be so careless.

It will be suggested that he (should) finish his homework today.

4.部分情态动词：

You could have lived with Tom.

You should have come five minutes earlier.

It was so near to the railway station. We could have walked to it.

A taxi wasn't necessary.

5.其他句型：

(1)It is (high) time that we went home (should go home).

(谓语用一般过去时态或should do)

(2)I would rather you came tomorrow.(谓语用一般过去时态)

(3)He talks as if he knew everything.
