Should型虚拟语气练习题
Should型虚拟语气练习题
1. 用于if引导的虚拟条件句中
在表示与现在或将来事实相反的非真实条件句中，谓语动词形式可用“should +
do”。如：
If she should refuse, they could be greatly disappointed.
【考例】 This printer is of good quality. If it _______ break down within the first
year, we would repair it at our expense. （2009年，天津）
A. would?B. should
C. could??D. might
2. 用于省略if的倒装句中
如果条件状语从句的谓语动词中含有should，可以省略连词if，而把should放在主语前构
成倒装。如：
Should he fail in the examination, he would have to wait for another year.
【考例】 ______ fired, your health care and other benefits will not be immediately
cut off. (2006年，湖北)
A. Would you be
B. Should you be
C. Could you be
D. Might you be
3. 用于主语从句中
在“It is ＋形容词／某些动词的过去分词 ＋ that从句”的结构中，从句的谓语动词
用“（should） + do ”虚拟语气形式来表示命令、要求和建议。这些形容词和过去分词常
见的有important（重要的）、essential（必要的）、necessary（必须的）、natural（自
然的）、decided（决定的）、ordered（命令的）、demanded（要求的）、proposed（建议
的）、required（要求的）等。如：
It is necessary that we (should) make everything ready ahead of time.
【考例】 It is essential that all these figures ________ twice. (2008年，四川

A. check B. checked
C. are checked D. be checked
4. 用于宾语从句中
表示主观判断、推测、建议、命令和要求的动词后的宾语从句中，谓语动词常采用
“（should） + do”的形式。这类动词包括advise（劝告）， ask（要求）， insist（坚
持）， order（下令）， suggest（建议）， command（命令）， demand（要求）， require
（要求）等。
He insisted that a deadline (should) be set for completing the task.
【考例】 The doctor recommended that you ______ swim after eating a large meal.
（2009年， 浙江）
A. wouldn’t B. couldn’t
C. needn’t D. shouldn’t
【疑难辨析】 动词insist如不表示要求，而表示“坚持己见”时，宾语从句用陈述语气。
同样，当suggest所表示的意思为“表明”或 “暗示”时，谓语动词也不采用“should +
do”的形式。如：
Jane insisted that she had done nothing wrong and that she should be treated properly.
The surprised look on his face suggested that he did not believe the fact.
【巧记速记】
常见动词后的宾语从句中需用“(should) + do”虚拟语气有：
一个坚持：insist
两个命令：order, command
三个建议：suggest, advise, propose
四个要求：demand, require, ask, desire
注意：在以it为形式宾语的复合宾语从句中也可以用虚拟语气，其形式为“（should） + do”。
这一句型中使用的形容词（宾补）与主语从句中的虚拟语气所使用的形容词相同。如：
We think it advisable that he (should) think deeply before acting.
5. 用于表语（或同位语）从句中
在表示命令、建议、劝告等含义的名词后面的表语（或同位语）从句中，谓语动词须用

6. 用于目的状语从句中
由in case, lest, for fear that引导的目的状语从句，谓语动词用“（should） + do”
结构，表示忧虑或目的。其形式通常为“... lest (in case, for fear that) + 主语 +
（should） + do”。如：
I will not make any noise, lest I should disturb you.
【考例】 The mad man was put in the soft-padded cell lest he ______ himself.（2009，
四川联考）
A. injure B. had injured
C. injured D. would injure
虚拟语气讲解及练习(有答案)
高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。

人教版高二英语虚拟语气的特殊形式练习题30题含答案解析
人教版高二英语虚拟语气的特殊形式练习题30题含答案解析
1. Had I known the result of the experiment earlier, I ______ my research in a different way. A. would conduct B. had conducted C. would have conducted D. conducted 答案：C。解析：这是一个省略if的倒装形式的虚拟语气句子。原句为If I had known the result of the experiment earlier，是对过去情况的假设。在这种虚拟语气中，从句用had done形式，主句要用would have done形式，表示与过去事实相反的假设，所以选C。A选项would conduct是对现在或将来情况假设的主句形式；B选项had conducted时态错误；D选项conducted是一般过去时，不符合虚拟语气的语法规则。 2. If he ______ here tomorrow, he would be able to see his old friend. A. were to come B. comes C. will come D. is coming 答案：A。解析：本题考查虚拟语气在if引导的非真实条件句中对将来情况的假设。根据语法规则，对将来情况假设时，从句可以用 were to do形式，表示可能性较小的假设。B选项comes是一般现在时，用于真实条件句；C选项will come是一般将来时，用于真实条件句；D选项is coming是现在进行时表将来，也用于真实条件句，都不符合虚拟语气的语法要求，所以选A。 3. Were it not for the help of my teacher, I ______ in this English competition. A. would not succeed B. would not have succeeded C. will not succeed D. did not succeed 答案：B。解析：这是省略if的倒装形式，原句为If it were not for the help of my teacher。这是对过去情况的假设，根据虚拟语气的语法，从句用were形式（表示现在或将来情况的假设也可用这种形式表示与事实相反），主句要用would have done形式，所以选B。A选项would not succeed是对现在或将来情况假设的主句形式；C选项will not succeed是一般将来时，用于真实条件句；D选项did not succeed是一般过去时，用于陈述过去的事实，不符合虚拟语气规则。 4. If only I ______ more time to study English when I was in junior high school! A. had B. had had C. have D. would have 答案：B。解析：if only引导的句子表示一种愿望，多使用虚拟语气。这里是对过去情况的愿望，从句要用had done形式。A选项had是一般过去时，不能准确表达这种虚拟的愿望；C选项have是一般现在时，不符合虚拟语气要求；D选项would have不是if only引导的对过去情况假设的正确形式，所以选B。 5. She looks as if she ______ ten years younger. A. is B. were C. has been D. had been 答案：B。解析：as if引导的从句在表示与事实不符的情况时，要用虚拟语气。这里表示她看起来好像年轻十岁（实际上不是），是对现在情况的虚拟，从句要用一般过去时（（be动词用were）。A选项is是一般现在时，用于陈述事实；C选项has been是现在完成时，不符合虚拟语气用法；D选项had been是对过去情况虚拟的形式，这里是对现在情况虚拟，所以选B。 6. I would rather you ______ me the truth yesterday. A. told B. had told C. tell D. would tell 答案：B。解析：would rather后面接从句时，如果是对过去情况的虚拟，从句要用had done形式。这里表示我宁愿你昨天告诉我真相，是对过去情况的假设，所以选B。A选项told是一般过去时，不符合这种对过去情况虚拟的要求；C选项tell是一般现在时；D选项would tell形式错误。 7. But for the rain, we ______ a nice holiday. A. should have B. would have had C. had had D. have had 答案：B。解析：but for表示“要不是”，引导的句子要用虚拟语气。这里是对过去情况的假设，相当于If it had not been for the rain，主句要用would have done形式，所以选B。A选项should have后面缺少成分；C选项had had是过去完成时，单独使用不能表达这种虚拟语气的完整意义；D选项have had是现在完成时，用于陈述事实，不符合虚拟语气规则。 8. If you ______ harder last term, you ______ better results in the exam. A. studied; would get B. had studied; would have got C. had studied; got D. studied; will get 答案：B。解析：本题是错综时间条件句。从句是对过去情况（（last term）的假设，要用had studied；主句是对过去情况假设下的结果（（在考试中的结果），要用would have got。A选项中studied是一般过去时，would get是对现在或将来情况假设的主句形式，不符合要求；C选项中got是一般过去时，不能表达这种虚拟假设下的结果；D选项studied是一般过去时，will get是一般将来时，都不符合错综时间条件句的虚拟语气规则，所以选B。 9. ______ it not been for the traffic jam, we would have arrived at the airport on time. A. Had B. If C. Were D. Should 答案：A。解析：这是省略if的倒装形式的虚拟语气句子。原句为If it had not been for the traffic jam。根据语法规则，这种情况下要用had来引导倒装句。B选项If如果使用则句子结构错误；C选项Were用于were型虚拟语气的倒装，这里是had型；D选项Should用于should型虚拟语气的倒装，不符合本题要求，所以选A。 10. He talks as though he ______ all the work himself, but in fact Tom and I did most of it. A. did B. has done C. had done D. would do 答案：C。解析：as though引导的从句在表示与事实不符的情况时要用虚拟语气。这里表示他说话的样子好像他自己做了所有的工作（实际上不是），根据in fact后面的内容可知是对过去情况的虚拟，所以从句要用had done形式。A选项did是一般过去时，不能准确表达这种虚拟；B选项has done是现在完成时，不符合虚拟语气用法；D选项would do是对将来情况假设的形式，这里是对过去情况虚拟，所以选C。 11. I wish I ______ at the concert last night. A. was B. were C. had been D. would be 答案：C。解析：wish引导的宾语从句表示与过去事实相反的愿望时，从句要用过去完成时。句中说希望自己昨晚在音乐会现场，昨晚是过去的时间，所以要用had been。A选项was用于一般过去时，不能表达与过去事实相反的虚拟语气；B选项were用于wish引导的与现在事实相反的虚拟语气；D选项would be用于表示将来不太可能实现的愿望，均不符合题意。 12. She would rather you ______ her the bad news yesterday. A. didn't tell B. hadn't told C. don't tell D. not tell 答案：B。解析：would rather后的从句表示与过去事实相反的愿望时，要用过去完成时。这里说她宁愿你昨天没有告诉她这个坏消息，昨天是过去的时间，所以要用hadn't told。A选项didn't tell用于与现在或将来事实相反；C选项don't tell是一般现在时，不符合语境；D选项not tell形式错误，均不正确。 13. He acts as if he ______ the only person in the world. A. is B. was C. were D. will be 答案：C。解析：as if / as though引导的从句表示与现在事实相反的假设时，不管主语是第几人称，be动词都要用were。这里说他表现得好像他是世界上唯一的人，这与实际情况相反，所以要用were。A选项is用于陈述事实；B选项was用于一般过去时，不符合虚拟语气规则；D选项will be表示将来，不符合语境。 14. I wish I ______ fly like a bird. A. can B. could C. should

虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。
