　　(2)用于if only＋句子＝How I wish＋(that)从句。如： If only I were a flying bird! ＝How I wish I were a flying bird! 我要是一只飞鸟该多好啊！

　　If only I had seen the film! ＝How I wish I had seen the film! 我要是看了那部电影该多好啊！ (3)用于表示建议、愿望、命令等动词后的宾语从句中，常见的动词有：demand，order，require，insist，suggest，recommend，urge，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。如： He suggested that we(should) start off early the next day. 他建议我们第二天早点儿出发。 They insisted that the boy (should) go with them. 他们坚决主张那个男孩子跟他们一起去。 注意：当suggest表示“暗示，表明”之意，insist表示“坚持说”之意时，suggest/insist后的宾语从句不使用虚拟语气，应使用陈述语气。如： 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. 那个人坚持说他没有偷钱。 2．用于主语从句中。 It is desired/suggested/proposed/recommended/necessary/ important/strange/natural/essential＋that从句，从句中的谓语动词用“should＋动词原形”，should可以省略。如： It is suggested that the meeting(should)

　　be put off till next week.人们建议会议推迟到下周。 It is strange that he(should) have acted toward his parents like that.(act在主句谓语动词is之前发生，所以要用should have acted，should可以省略) 真奇怪他竟然那样对他父母。 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”，should可以省略。如： My idea is that we(should) think it over before accepting it. 我的观点是在接受之前我们要反复考虑。 We all agree to his suggestion that we (should)

　　go to Dalian for sightseeing. 我们都同意他让我们去大连旅游的建议。

　　三、虚拟语气在as if/as though引导的从句中的运用 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，从句谓语动词用一般过去时；如果as if引导的从句谓语动词所表达的动作先于主句谓语动词所表达的动作，从句谓语动词用过去完成时；如果as if引导的从句谓语动词所表达的动作后于主句谓语动词所表达的动作，从句谓语动词用过去将来时。如：

　　He looks as if he were an artist.(同时) 他看起来像个艺术家。 She speaks English so fluently as if she had studied English in America.(先于) 她讲英语如此流利，好像她在美国学过英语。 He learns English so hard as if he would go to the USA.(后于) 他如此努力地学英语，好像他要去美国。 四、虚拟语气在定语从句中的运用 It is (high) time (that)．..句型中，定语从句的谓语动词用一般过去时，或用should＋动词原形(其中should不能省略)。此句型意为“(现在)该……了”，用来表示提议。如： It is(high) time that you went to school. 你该去上学了。 It is (high) time that we should start out. 我们该出发了。 考 点 警 示 使用虚拟条件句时要注意以下几点： 1．当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为“错综时间条件句”。动词的形式要根据它所表示的时间做出相应的调整。如： If you had followed my advice just now，you would be better now. 如果你刚才听了我的建议，你现在就好多了。 If you had studied hard before，you would be a college student now. 如果你以前好好学习的话，你现在就是一名大学生了。 2．if省略句的应用。 在虚拟条件状语从句中可省略if，把were，had，should提到句首，变为倒装句式。如： If I were at school again，I would study harder. →Were I at school again，I would study harder. 如果我还有上学的机会，我会更加努力地学习。 If you had come earlier，you would have caught the bus. →Had you come earlier，you would have caught the bus. 如果你来得早些，你就能赶上公共汽车。

　　If it should rain tomorrow，we would not go climbing. →Should it rain tomorrow，we would not go climbing. 如果明天下雨的话，我们就不去登山了。 注意：当省略的条件状语从句中的谓语动词是否定形式时，不能用动词的缩略形式。如：可以说：Were it not for the expense，I would go abroad now.但不能说：Weren't it for the expense，I would go abroad now. 3．含蓄条件句的应用。 有时为了表达的需要，在虚拟语气中并不总是出现if引导的条件状语从句，而是通过其他手段来代替条件句。如： What would you do with one million dollars(＝if you had one million dollars)? 如果你有100万美元，你会做什么？ Without your help，we couldn't have finished the work ahead of time. ＝But for your help...＝If it had not been for your help... ＝Had it not been for your help，... 没有你的帮助，我们不可能提前完成这项工作。 I was ill that day. Otherwise，I would have taken part in the sports meeting.(副词) 那天我病了。否则，我就参加运动会了。 He telephoned to inform me of your birthday，or I would have known nothing about it.(连词) 他打电话通知了我你的生日，否则，我对此一点儿都不知道。 走向高考 · 高考总复习 · 人教版 · 英语
