的形式用_但在单数人称中也可用was；与过去事实情况相反，则谓语动词用_。【答案】1.虚拟；愿望2.过去时；were；过去完成时虚拟语气一、虚拟语气在名词性从句中的运用1用于宾语从句中(1)wish后面的宾语从句一般用虚拟语气，表示一种不可能实现的愿望。其谓语动词的构成形式为：i wish (that) i were a bird and could fly freely in the sky.我多么希望我是一只小鸟，能在空中自由地飞翔。i wish (that) i had met that film star yesterday.我多么希望我昨天碰到了那个电影明星。(2)用于表示建议、愿望、命令等词后的宾语从句中，常见的动词有：demand，order，require，insist，suggest，propose，advise等。宾语从句中的虚拟语气结构为“should动词原形”，should可以省略。he suggested that we (should) start off early the next day.他建议我们明天早点出发。the doctor ordered that the patient (should) be sent to hospital without delay.医生命令不要延误，马上送病人到医院。they insisted that the boy (should) go with them.他们坚持要那个男孩和他们一起去。(3)在would rather后的宾语从句中，也用虚拟语气，其谓语动词用过去式。i would rather they didnt hear of the news.我宁愿他们没听到这个消息。(4)当suggest表示“暗示，表明”之意，insist表示“坚持认为”之意时，suggest/insist后的宾语从句谓语动词不使用虚拟语气形式，而使用陈述语气形式。the smile on his face suggested that he was satisfied with our work.他脸上的微笑表明他对我们的工作很满意。the man insisted that he had never stolen the money.那个人坚持说他从来没有偷过钱。2用于主语从句中it is desired/suggested/proposed/necessary/important/strange/natural/a pity/essentialthat从句，从句中的谓语动词用“should动词原形”，should可以省略。it is suggested that the meeting should be put off till next week.大家建议把会议推迟到下周。it is strange that he should have acted toward his parents like that.很奇怪，他竟然那样对待他的父母。(act动作在主句谓语动词is动作之前，要用should have过去分词)注意以上句式也可以用陈述语气。its strange that he didnt come yesterday.真奇怪，他昨天没来。its a pity that you cant dance.真遗憾，你不能跳舞。3用于表语从句和同位语从句中在suggestion，proposal，order，plan，idea，request，advice等名词后的表语从句和同位语从句中要用虚拟语气。其构成是“should动词原形”。my idea is that we should think it over before accepting the plan.我的意见是我们接受这个计划之前应三思。we all agreed to his suggestion that we should go to dalian for sightseeing.我们都同意他的建议，应去大连旅游。二、as if/as though用在虚拟语气中如果as if引导的从句谓语动词与主句谓语动词所表达的动作同时发生，as if从句用过去时；如果as if从句谓语动词先于主句谓语动词，as if从句谓语动词用过去完成时；如果as if从句谓语动词后于主句谓语动词，as if从句用过去将来时。he looks as if he were an artist.(同时)他看起来好像是个艺术家。she speaks english so fluently as if she had studied english in america.(先于)她的英语说得如此流利，好像她在美国学过英语似的。三、虚拟语气用于定语从句中it is (high) time (that).句型中，定语从句的谓语动词用过去式或should动词原形(其中should不能省略)。此句型意为“(现在)该”，用来提议。it is (high) time that you went to school.该是你上学的时间了。it is (high) time that we should start out.我们该出发了。四、用于if only引导的感叹句中if only i were a flying bird!how i wish i were a flying bird!如果我是一只能飞的鸟多好啊！if only i had seen the film!how i wish i had seen the film!多么希望我已看了那部电影！.单项填空1how i wish every family_a large house with a beautiful garden.ahasbhadcwill have dhad had【解析】句意：我多希望每个家庭都能有一所带有美丽花园的房子。wish后的宾语从句用虚拟语气，故排除a和c；该句谈的是现在的愿望，从句应用一般过去时，所以选b。【答案】b2he suggests we_to the cinema at once，otherwise we _late.amust go；are bgo；will be cwill go；will be dwould go；are【解析】考查虚拟语气。句意：他建议我们马上去看电影，否则我们就迟到了。suggest“建议”，其后的宾语从句中谓语为should动词原形，should可以省略；otherwise后的句子表示很可能发生的事情，用陈述语气，所以使用将来时。【答案】b3what courses are you going to take next term?i dont know. but its about time_on something.aid decide bi decidedci decide dim deciding【解析】its (high/about) time.后面的从句的谓语动词通常用过去式。【答案】b4he looked as if he_the answer.aknew bhad knowncknows dhas

studied【解析】此题表示的是与过去事实相反的情况，wish后的宾语从句中的谓语动词要用过去完成式，所以用had studied。【答案】d6it was a pity that you missed the famous star yesterday.if only i_to my hometown!adidnt return bhadnt returnedcshouldnt return dwouldnt return【解析】本题考查if only引导的与过去事实相反的虚拟语气，因此用过去完成时。【答案】b7it is strongly suggested that measures_students to cheat in the exams.abe taken to prevent bbe taken to forbidcare taken to prevent dare taken to forbid【解析】句意：强烈建议采取措施禁止学生考试作弊。suggest作“建议”讲，从句应使用虚拟语气，谓语动词要用should动词原形或把should省略，由此排除c、d两项；prevent的用法是prevent sb.from doing sth.，与题意不符。而forbid的用法是forbid sb.to do sth.，符合题意。【答案】b8tom recommended me that i_accept the invitation.acould bmustcshould dmight【解析】recommend后面的宾语从句的谓语动词要使用虚拟语气，即should动词原形或者只用动词原形。因此c项为正确答案。【答案】c9do you mind if i keep pets in this building?_.aid rathe
