时间 if从句谓语动词形式 主句谓语动词形式
现在 过去式(be的过去式用were) should/would/could/ might＋动词原形
过去 had＋过去分词 should/would/could/ might＋have＋过去分词
将来 should＋动词原形 should/would/could/might＋动词原形
过去式
were to＋动词原形
(2)错综时间的虚拟语气
当从句、主句所表示的行为发生的时间不一致时，动词的形式要根据它所在的时间作出相应的调整。

if虚拟条件状语从句中出现were, had, should时，可省略if，把were, had, should提到句首，变为倒装句式。21*cnjy*com

3. 表语从句中的虚拟语气
句子主语是表示“愿望”“劝告”“ ( http: / / www.21cnjy.com )建议”“主张”“命令”“决定”等行为动词派生出来的同根名词时，其表语从句常用虚拟语气“(should) ＋动词原形”结构。这类名词有suggestion, proposal, request, advice, decision, requirement等。www-2-1-cnjy-com

1. 虚拟语气可用于as if/though 引导的表语从句和方式状语从句：
时间 从句谓语动词形式

过去 had＋过去分词

注意：if only意为“但愿，要是……就好了”；only if意为“只有……(才)”，引导条件状语从句，不用虚拟语气。2·1·c·n·j·y
3. 在It is (hi ( http: / / www.21cnjy.com )gh/about/the very) time＋(that)从句中，从句中的谓语动词通常用过去式或“should＋动词原形”(此时should不可省略)表示虚拟，意为“是时候该干某事了”。

It’s high time ( http: / / www.21cnjy.com ) that we should take action to protect the water resources.

5. 情态动词＋have＋done... 表达“本该”的意思。

might have＋done... 本来可能发生(但是没有发生)
needn’t＋have＋done... 本来不必做某事(但做了)

Patience is of gre ( http: / / www.21cnjy.com )at importance in our daily life. Once I waited a bus to come at a stop. 30 minutes pass, but no bus came. Both upset and annoyed, I decided to walk on feet. But no sooner had I left when the bus arrived. I thought if I had waited for one more minute, I would have caught it. If I chose to take a next bus, I would have to wait for other 30 minutes. Only then do I realize my problem. Being impatient will possible waste all the effort that we have put it in. Now whenever I am close to lose my patience, I’ll think of this experience.
