名词性从句中的虚拟语气
名词性从句中的虚拟语气名词性从句是高中英语学习中重要的语法项目之一，它要紧包括主语从句、宾语从句、表语从句和同位语从句。
由于这四种从句在句中均具出名词的特点，因此统称为名词性从句。
在某些名词性从句中谓语动词需要用虚拟语气，要紧包括以下几点。
一、宾语从句1.在表示“坚持、要求、命令、建议”之类的动词后的宾语从句中，谓语动词要用“should+动词原形”，should能够省略。
如此的动词有：一个“坚持”（insist），两个“命令”（order,command），三个“建议”（suggest,advise,propose），四个“要求”（ask,demand,request,require）。
例如：Heinsiststhatshe(should)come.他执意要她来。
Hedemandedthathe(should)besenttoworkthere.他要求把他派到那里工作。
注意：当suggest表示“暗示，说明”，insist表示“坚持说（以为）”时，其后的宾语从句中的谓语动词要用陈述语气。
例如：Alltheevidencesuggeststhathestolethemoney.所有证据都说明是他偷了钱。
Heinsistedthathewasinnocent.他坚持说他是无辜的。
2.在动词wish后面的宾语从句中，若是表示与以后事实相反或不可能实现的愿望，用should/would/could/might+动词原形；若是表示与此刻事实相反的一种愿望，谓语动词用过去式；若是表示与过去事实相反的一种愿望或已经发生的遗憾的情形，用“had+过去分词”。
例如：Iwishyouwouldn’tleaveyourclothesalloverthefloor.我真希望你不把衣服丢得满地都是。
IwishIweretaller.我若是个子高一些就好了。
IwishIhadn’teatensomuch.我倒希望我没有吃这么多。
名词性从句中的虚拟语气
虚拟语气——名词性从句中的虚拟语气在英语中有陈述语气，用于平铺直叙客观情况。
而虚拟语气，顾名思义，不是真实的客观的情况，而是主观的（说话人）命令，要求，建议等，事实上并未发生。
在形式上用should+do来标明这是虚拟语气。
巧记1：名词性从句中的虚拟语气名词性从句: 主语从句，宾语从句，表语从句，同位语从句。
1) 宾语从句: 10个动词+that sb. (should) do例：I suggest that he (should) work hard.我建议他努力学习。
巧记2：与suggest用法相同的10个动词思考：为什么这些词要用虚拟语气呢？因为：你命令要求建议或坚持让某人去做某事，事实他还没做，这就是虚拟语气。
所以要注意：suggest表暗示表明；insist表坚称时，不用虚拟语气。
He insisted that he didn't cheat in the exam.他坚持说他没作弊。
His embarrassed look suggested that he was lying.他尴尬的表情表明他在撒谎。
2)主语从句：It is/was +10个动词（-ed）+sb.(should) do例：①It is suggested that he should work hard.据建议他该努力学习。
注意：It 作形式主语使用虚拟语气的句式还有②It is important, necessary，strange…that+ (should) do③It is a pity, a shame, no wonder… that+ (should) do④It is (high/about) time that sb. should do/did sth.(should不可省略）到某人做某事的时间了，事实上还没做，所以用虚拟。
注意：在句式②③中，should除译为应该外，有时表竟然。
名词性从句中的虚拟语气的用法解析
名词性从句中的虚拟语气的用法解析名词性从句中的虚拟语气当名词性从句（主语从句、宾语从句、表语从句和同位语从句）中的谓语动词使用了某种特殊形式或者该从句使用了某些具有特定意义的名词、形容词或分词时，可以使用虚拟语气。
1. 主语从句(1) It is important that she (should) cooperate with usIt was unnecessary that he (should) get here so early.He says it is fortunate that she (should) take the first prize.It is strange that he (should) leave without telling us.It is surprising/amazing/pleasing that she(should) win over her mother.在“it + be + adj. + that clause ”的句型中，形容词表示“必须的”、“重要的”、“适当的”、“自然的”、“不可能的”、“紧迫的”等意义时，主语从句常用虚拟语气。
这类形容词还有advisable, desirable, essential, impossible, natural, possible等。
形容词表示“惊讶的”、“失望的”、“懊悔的”等意义时，主语从句常用虚拟语气。
形容词是dreadful（可怕的），funny等词时，这种句型中的主语从句也可用陈述语气。
（2）It is ordered that the classroom (should) be kept in order.It is desired that every student (should) obey the school rulesIt is suggested that we (should) start the work at once.表示“命令”、“建议”、“要求”意义的动词，如advise, arrange, demand, propose, recommend, request, require等用被动语态时，主语从句要用虚拟the time being.Would not you rather your child went to bed early? 短语would rather后面的宾语从句中常用虚拟语气。

近几年高考对于虚拟语气的考查主要集中在语法填空和书面表达中，语法填空涉及动词提示词的填空中多次出现对虚拟语气的考查，考查难度不大。
一、主语从句中的虚拟语气：1. It is／was + 形容词+ that从句当形容词为important, necessary，strange，natural，appropriate, proper, right, desirable, essential, surprising, unthinkable等或名词短语a good idea时。
2. It is／was + a pity / a shame / a surprise / no wonder + that从句3. It is demanded / suggested / ordered / required / ….that-clause注意：这种主语从句由连词that引导，虚拟语气为“（should）动词原形”。
其中should可省略。
should 常译成“应该、必须、竟然”。
It is important and necessary that we (should) master a foreign language.精通一门外语对我们来说是重要而且必要的。
It is proper that an independent inquiry (should) take place.进行独立调查很合适。
It is strange that he (should) refuse your help.他竟然拒绝你的帮助真是奇怪。
It is surprising that you (should) not understand me!你竟然不理解我，真令人吃惊！It’s a pity that you (should) miss a good chance.你竟然错过一个好机会真是遗憾。
It is suggested that he (should) not spend too much time watching TV.有人建议他不应该花太多时间看电视。
It is proposed that the plan (should) be delayed.有人建议推迟这项计划。
—Yang Liwei has won great honour for our country.—Who is Yang Liwei?—What a question! It is surprising ________ the first spaceman in China.A. you didn’t know our national heroB. to you not to know himC. you should know nothing aboutD. you knew nothing about答案：C思路分析：在it is surprising后的that从句中，谓语要用“should +动词原形”，其中should 含“竟然”之意，是最佳答案。
二、宾语从句中的虚拟语气：1. wish后宾语从句须用虚拟语气：⑴表示与现在事实相反的愿望，从句谓语须用过去式（were）；⑵表示与过去事实相反的愿望，从句谓语须用had+过去分词；⑶表示将来没有把握或者不大可能实现的愿望，从句谓语须用would / could / might+动词原形。
2. 与坚持、命令、建议及要求四类词相关的宾语从句中需要用（should）+动词原形的虚拟语气。
这四类词包括⑴一个坚持：insist；⑵两个命令：order，command；⑶三个建议：advise，suggest，propose；⑷四个要求：demand，request，require，desire / ask。
I wish (that) I could fly freely in the sky.我希望我们能够在天空中自由飞翔。
I wish I had seen you at the party yesterday.我真希望在昨天的宴会上见到你。
I wish I would have another chance next year.我希望下一年还有机会。
He ordered that the students (should) wash the clothes every week by themselves.他命令学生们每周自己洗衣服。
The doctor suggested that she (should) have an operation at once.医生建议她立刻手术。
（should省略后，she后会紧接着have，这是正确的）Mr. Li required the computer equipment referred ________ used in every classroom.A. should beB. have to beC. to beD. to being答案：C思路分析：句中referred to是过去分词短语，作the computer equipment 的定语，意为“被提到的计算机设备”；在表示“要求”的require, request, ask, demand等动词后的宾语从句的谓语要用“(should+)动词原形”，所以从句的谓语动词是be used，省略了should。
三、表语从句中的虚拟语气：1. 在名词“suggestion, proposal, idea, plan，order, advice, desire, requirement, request, command, decision, recommendation等”作主语时后面的表语从句中，用“should+动词原形”，其中should可省略。
2. as if ( as though)引导的表语从句中的虚拟语气。
My advice is that we (should) get more people to attend the conference.我的建议是我们应该让更多的人参加会议。
My demand is that she (should) come to see me once a week.我的要求是她应该一周来看我一次。
It seems as if the meeting would never end.看来会议没完没了。
（与将来相反）It seems as though he had been there many times.好像他已经去过那里好多次了。
（与过去事实相反）It seems as if nobody knew what happened.好像没有人知道发生了什么事。
What the customers _________ from the company is that the goods _________ right to their homes.A. requested, deliverB. demand, be deliveredC. request, should deliverD. demand, delivered答案：B思路分析：从is可知what从句中的谓语动词request或demand用一般现在时，表示一般状况；而动词request / remand有关的表语从句用虚拟语气：（should）+动词原形。
第二空动词deliver与主语the goods是被动关系，省略should后，填be delivered。
四、同位语从句中的虚拟语气：与表示“决定、主张、要求、建议、命令”的动词相对应的名词构成的同位语从句中常用（should）+do结构。
The requirement that students (should) learn to protect themselves is successfully carried out in most schools.学生必须学会保护自己，这一要求在大多数学校都能顺利实施。
I made a proposal that we (should) hold a meeting next week.我提议我们应该下周开个会。
He made the demand that all the students (should) go home at once.他作出要求，所有学生要立刻回家。
You’d better follow my advice that he English hard with the help of his mother.A. studiesB. studiedC. studyD. must study答案：C思路分析：本题考查虚拟语气，在advice等词后跟的同位语从句中需要（should）+动词原形的虚拟语气，其中should可以省略。
因此选择C选项。
1. Jane’s face suggested that she ________ ill, and her parents suggested that she________ a medical examination.A. be; should haveB. was; haveC. should be; hadD. was; has2.
