动词虚拟语气的用法、比较等级形式及其示例:


I.要点


表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中。


1、虚拟语气的构成


情景条件从句的谓语动词主句的谓语动词


与现在事实相反动词过去式(be要用were)should


+动词原形


would


与过去事实相反had+过去分词should


+have+过去分词


would


与将来事实相反1、动词过去时


2、should+动词原形


3、were to+动词原形should


+动词原形


would


注:如果条件从句谓语动词包含有were或had,should,could有时可将if省去,但要倒装。如:


Had you(If you had)invited us,we would have come to your party.


2、虚拟语气在各种从句的应用


(1)在主语从句中用来表示惊奇、惋惜、理应如此等,其谓语形式是"should(可省)+动词原形",常用于以下三种句型中。


句型一:It is necessary(important,natural,strange,etc)that…


句型二:It is a pity(a shame,no wonder,etc)that…


句型三:It is suggested(requested,proposed,desired,etc)that…


如:It is strange that he(should)have done that.


It is a pity that he(should)be so careless.


It is requested that we(should)be so careless.


(2)在宾语从句中用于suggest,propose,move,insist,desire,demand,request,order,command等动词后的宾语从句中,表间接的命令和建议。其谓语形式是"(should)+动词原形"。如:


I suggest that we(should)go swimming.


(3)在表语从句中,表示间接的命令,要求、请求、建议、决定等,主句中的主语通常是suggestion,proposal,request,orders,idea等。从句谓语形式是"(should)+动词原形"。如:


His suggestion is that we(should)leave at once.


(4)在同位语从句中,谓语形式是"(should)+动词原形"。如:


We received order that the work be done at once.


(5)在It is time that…句型中,其谓语动词形式是"动词的过去式"或


"should+动词原形",should不可省。如:It's time(that)we went(should go)to school.


II.例题


例1 We had hoped that he ____ longer.


A stays B have stayed C stayed D would stay


解析:该题正确答案为D。had hoped表示"本希望",同样用法的动词还有think,expect等,后面的句子需用虚拟语气


例2"Mary wants to see you today".


"I would rather she ____ tomorrow than today."


A comes B came C should come D will come


解析:该题正确答案为B。would rather后面的从句需用虚拟语气,用动词过去时表示。www.examw.com
