初中英语语法专项虚拟语气

1、初中英语语法专项练习十四虚拟语气1. When a pencil is partly in a glass of water, it looks as if it _. A.breaks B.has broken C.were broken D.had been broken 解析：答案为C。本题考查的是as if 引导的让步状语从句中的语气问题，as if引导的状语从句如果与事实一致，不用虚拟语气，如果与事实相反，应用虚拟语气。题中“当铅笔的一部分浸在水中，铅笔看上去好像断了”。而实际上铅笔并未断，与事实相反，前半部分陈述是一般现在时，因而本句是对一般现在时的虚拟，用were broken。

2、 2. I didnt see your sister at the meeting. If she _, she would have met my brother. A.has come B.did come C.came D.had come 解析：答案为D。本题考查的是if条件句中的虚拟语气。题意是：我在会议上没看到你姐姐，故你姐姐没来。因此如果“她来了”与事实相反，前面一句交代了虚拟语气的时态是一般过去时的虚拟，所以if从句中用had+过去分词。 3. If he _, he _that food. Luckily he was sent to the hospital immedi

3、ately. A.was warned; would not take B.had been warned; would not have taken C.would be warned; had not taken D.would have been warned; had not taken 解析：答案为B。本题考查的是条件状语从句与主句表示与事实相反时虚拟语气的用法。根据下一句语境可知，他事先并没有得到警告，表示过去时间的虚拟语气，故选B。 4. If there were no subjunctive, English _ much easier. A.will be B.would

4、have been C.could have been D.would be 解析：观察题干，可知全句表达的是与现在事实相反的虚拟语气。故答案为D。 5. The guard at the gate insisted that everybody _ the rules. A.obeys B.obey C.will obey D.would obey 解析：根据insist后的宾语从句谓语要用(should) do形式规律，可定正确答案是B。 6. I wish I _ you yesterday. A.seen B.did see C.had seen D.were to see 解析：此题

5、表与过去事实相反的原望，答案应为C。 7. If he _ , he _ that food. Luckily he was sent to the hospital immediately. A.was warned;would not take B.had been warned;would not have taken C.wuld be warned;had not taken D.would have been warned;had not taken 解析：从对话看，是表达与过去事实相反的虚拟语气，故答案为B。 8. Without electricity human life _

6、 quite different today. A.is B.will be C.would have been D.would be 解析：without引出一个含蓄条件句，主句表述的是与现在事实相反的虚拟语气，故答案为D。 9. When a pencil is partly in a glass of water, it look as if it _. A.breaks B.has broken C.were broken D.had been broken 解析：放入水中的铅笔看上去是断的，但实际上并非如此，因此是与现在的事实相反，这时as if从句谓语要用一般过去时，故答案为C。

7、10. I didn he _ , he would have said hello to me. A.would come B.had come C.came D.did come 解析：观察题目上下文，特别是第二句的主句谓语为 would have said，可知if从句表述的是与过去事实相反的愿望，因此答案为B。 11. _ it _ for your help, I couldn have made any progress. A.Had;not been B.Should;not be C.Did;not be D.Not;be 解析：根据主句谓语形式，可知从句要用had done形

8、式，故应选A，Had it not been for your helpIf it had not been for your help.（要不是你帮忙的话） 12. Mr Smith was badly ill, or he _ our dinner party. A.should come to B.would have attended C.would come to D.should have attended 解析：or可引导含蓄条件句，表达虚拟语气。根据此题内容，可知是与过去事实相反的假设，故答案为B。 练习： 一 用所给动词的适当形式填空： 1.The boy isnt hung
