1、高中英语名词性从句中的虚拟语气1. 通过本课的学习，能够全面掌握名词性从句中虚拟语气的基本用法。2. 通过本课的学习，能够初步了解虚拟语气在不同类型名词性从句中的具体用法。重点：掌握与坚持、命令、建议、要求四类词相关名词性从句中虚拟语气的用法。 难点：wish 宾语从句中虚拟语气的用法。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 iswas + 形容词+ that 从句当形容词为 important, necessary，strange ，natural，appropr
2、iate, proper, right, desirable, essential, surprising, unthinkable 等或名词短语 a good idea 时。2. It iswas + 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
3、 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！Its a pity t

It is surprising _ t
5、he first spaceman in China.A. you didnt know our national hero B. to you not to know himC. you should know nothing about D. 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：表示与现在事实相反的愿望，从句谓语须用过去式 （were）；表示与过去事实相
6、反的愿望，从句谓语须用 had+过去分词；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。第 1 页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。这四类词包括一个坚持：insist；两个命令：order，command；三个建议：advise， suggest，propose；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 w
7、ish 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
8、紧接着 have，这是正确的）Mr. Li required the computer equipment referred _ used in every classroom.A. should be B. have to be C. to be D. 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
9、，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 conferenc
10、e.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 _
11、 from the company is that the goods _ right to their homes.A. requested, deliver B. demand, be deliveredC. request, should deliver D. 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
12、should 后，填 be delivered。四、同位语从句中的虚拟语气：第 2 页与表示“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
13、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。Youd better follow my advice that he English hard with the help of his mother. A. studies B. 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.
14、 Janes face suggested that she _ ill, and her parents suggested that she_ a medical examination.A. be; should have B. was; haveC. should be; had D. was; has2.

My suggestion is that she _ more exercise, which will do a lot of good to her.A. takesB. must takeC. takeD. took答案：BBBCDC思路分析：1. 第一个 suggest 意为“表明”，宾语从句不用虚拟语气，谓语用 was；第二个 suggest 表示“建议”，宾语从句用虚拟语气“should+动词原形”，should 可以省略。2. 每一家都有一个带花园的大房子是一种很难实现的愿望，wish 后的虚拟语气用过去 式表示对现
17、在或将来的虚拟。3. insist 在此句中表示“坚决要求”，后接的宾语从句要用虚拟语气，形式是 should+动 词原形，should 可省略。4. order 的宾语从句用虚拟语气“（should）+动词原形”，因为美猴王是被逮捕的，用被 动语态，前面省略了 should。句意：玉帝命令立刻逮捕美猴王。5. 从 when 引导的时间状语从句可知 “study business ”是发生在 wishes 前，是与过去 事实相反的希望，所以用过去完成时（had studied business）。6. 主语是 suggestion，表语从句的谓语用“should+动词原形”的虚拟结构，should 可以 省略。第 3 页
