1、 虚拟语气在名词性从句中的用法l. 虚拟语气在主语从句中的用法：在“It is +adj/过去分词/某些特定的名词+ that”这类句型里，that 所引导的主语从句中的谓语动词常用 “should 十动词原形”结构。如：It is important that every member （should） inform himself of these rules. 1:适用于这句型的形容词有：important，strange ， amazing, astonishing, normal, essential, natural，necessary etc.2: 接这种结构的过去分词有：dec
2、ided, ordered, required, requested, demanded, suggested, etc.e.g. It is requested that all members be present at the meeting.EX: It is politely required by the managers that radios _ after 11 oclock at night. (CET-4)A: were not played B: not be played C: not to play D: did not play3：接这一结构的名词有：advice
3、, suggestion, decision, desire, demand, request, requirement, wish, proposal, idea, order 等。还有“It is a pity, it is a shame, it is no wonder 等 + that” 等结构后的主语从句中.

4、杯水这是专家给的建议2. 虚拟语气在宾语从句中的用法（1）在动词 wish 后的宾语从句中，表示与现在或过去的事实相反，或对将来的主观愿望，从句通常省略连词 that.1）表示对现在情况的虚拟：从句动词用过去式或过去进行式（be 动词一般用 were） 。如： I wish I knew the answer to the question. 我希望知道这个问题的答案。 （可惜不知道） ；2）表示对过去情况的虚拟：从句动词常用“had 十过去分词 ”。如：I wish （wished） I hadnt spent so much money. 我后悔不该花那么多钱。 （实际上已经花掉） ；3）
5、表示对将来的主观愿望：谓语动词形式为“would 十动词原形” 。此时要注意，主句的主语与从句的主语不能相同，因为主句的主语所期望的从句动作能否实现，取决于从句主语的态度或意愿（非动物名词除外） 。如： I wish it would stop raining. I wish you would come soon. （2）在 suggest，ask, demand，order ，propose，insist，command，request ，desire, decide, beg, deserve, determine, prefer, recommend 等动词后的宾语从句中，谓语动词用“
6、should + 动词原形”，表示建议、要求、命令等。结构：should + 动词原形，should 可以省略。如：I demand that he （should） answer me immediately. 我要求他立刻答复我。完成句子：1：Your silence suggested that _ (你同意我的观点). (agree)2: He suggested that _ （我带一部相机）(bring)3: The man insisted that _ (他无罪) and that _ (他应该被释放). (guilty， set)（3）在 would rather, woul
7、d prefer 等从句中也要使用虚拟语气。意思是“某人宁愿要另一个人干某事” 。若是对现在或将来的虚拟，使用一般过去时，若是对过去的虚拟，则使用过去完成时。翻译：明天别来，我宁愿你后天来。3. 虚拟语气在表语从句/同位语从句中的用法表语从句、同位语从句中的虚拟语气在 suggestion， proposal， order， plan， idea， advice， decision 等需要有内涵的名词后面的表语从句、同位语从句中，要使用虚拟语气。其谓语动词应用：should原形动词。另外连接从句的 that 不能省略。 例：My suggestion is that we should go
8、there at once. What do you think of his proposal that we should put on a play at the English evening?（2）虚拟语气在一些状语从句中的用法1）在带有 even if/ even though 引导的让步状语从句的主从复合句中，主句和从句都用虚拟语气，动词形式与含有非真实条件句的虚拟语气相同。如：Even if he had been ill， he would have gone to his office. 即使生了病，他也去办公室。2）由 as if 或 as though 引导的状语从句表
9、示比较或方式时。从句谓语形式为动词的过去式（be 用were）或“had 十过去分词”。如：He treated me as if I were a stranger. 他那样对待我，好像我是陌生人似的。She talked about the film as if she had really seen it. 她谈论那部影片，就好像她确实看过一样。注：如果表示的事情可能会发生，那么方式状语从句中的谓语动词可用陈述语气。3）在 in order that 或 so that 引导的目的状语从句中，谓语动词多用 “could 或 might（有时也用should）+ 动词原形”。如：Mr. G
10、reen spoke slowly so that his students could （might ） hear clearly. 格林先生说得很慢，好让学生听清楚。 4）if only 表示“但愿” “要是就好了”用法跟 wish 相同，但其情感意义比 wish 强。E.g.: If only he had followed your advice. If only I were taller. If only the rain would stop. （3） 虚拟语气在定语从句中的用法：在“It is time （that） ”句型中，定语从句的谓语动词常用虚拟语气表示将来，动词形式一
11、般用过去式，意思是“ 该干某事的时候了 ”。（4） 虚拟语气在简单句中的用法（1）情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌，或委婉的语气，常见于日常会话中。如： It would be better for you not to stay up too late. 你最好别太晚睡觉。（2） 用“may + 动词原形”表示“祝愿” ，此时 may 须置于句首（多用于正式文体中） 。如：May you be happy！祝你快乐！ May good luck be yours.祝你顺利。练习解析：1.
