虚拟语气 导学案-2025届高三英语上学期一轮复习专项.docx

1、 虚拟语气第二节具体考点解析【考点一、虚拟语气在条件句中的使用】1）条件句的从句和主句的谓语动词形式表及几点说明条件句的从句和主句的谓语动词形式表如果假设的情况与事实相反，或是根本不可能发生或是发生的可能性很小，这就是非真实条件句，即虚拟条件句。虚拟条件句的谓语动词的形式是不同于真实条件句的谓语动词形式的。虚拟条件句有三种情况。虚拟条件句主句例句与现在事实相反的假设If+主语+动词的过去式 （be动词用were）主语+should, would, could, might+动词原形If I had enough money, I would buy the house.与过去事实相反的假设If

2、 + 主语+ had +过去分词主语+should, would, could, might+ have+过去分词If you had listened to me yesterday, you would have finished the work.与将来事实相反的假设If+主语+动词的过去式If +主语+were to +动词原形If + 主语+should+动词原形主语+should, would, could, might+动词原形If it were to rain tomorrow, the sports meeting would be put off.特殊结构的条件句：“If

3、 it were not for”或“If it had not been for”, 前者与现在事实相反，后者与过去事实相反。相当于but for或without。例如：If it werent for your help，he could never go to collegeIf it hadnt been for the captains efforts, the ship could have sunken. 虚拟条件句的谓语动词形式表的灵活应用 A 用进行时替换相应的一般时: 如用过去进行时代替一般过去时，表示与现在事实相反。例如：If you were learning to s

4、wim, I would take you to watch the match. If we were getting along well with Jack, we should invite him to join us. B用完成进行时替换相应的完成时: 如用过去完成进行时替换过去完成时，仍表示与过去事实相反。例如：If it had been raining yesterday，I would not have come hereIf you had been listening more attentively, you would not have missed so much

5、 information. 混合型的条件句按照条件句的谓语动词形式表，其主句和从句的谓语动词是相互呼应的，有着固定的搭配关系。但有时主句和从句的谓语动词并不相互呼应，这种条件句叫混合条件句。较多见的混合型条件句是从句用过去完成时（指过去行为），而主句用一般时（指目前状态）。例如：He would pass the test if he had taken my advice If we had driven in turns yesterday, you would feel better now. 2）虚拟条件句的省略情况 省略if的虚拟条件句：如果虚拟条件句的谓语部分有were，had和s

6、hould时，可省略if，把were，had和should放到从句主语前面去。例如：Had you not helped me，I should have failed. Had it not been for the timely rain, we would have lost everything. Were it to rain tomorrow, we would have to put off the game. Should they refuse our request, we could show them this picture. 如果没有were，had和should则

7、不能省略if，当然也不能倒装。 条件从句的省略He could not fly（if he tried）If only I had more money！If only I were a bird! suppose 或 supposing =what ifSupposing it were so？（=Supposing it were so，what would happen？）suppose后也可用陈述语气。3）含蓄的虚拟语气But for air and water，nothing could liveHuman beings could perish without the other

8、forms of lives. She would have come here，but she was too busy with her homeworkYou could have passed the test, but you knew too little. 【考点二、虚拟语气在宾语从句中的应用】 1）宾语从句在表示提议、要求、命令、意志等动词后，可用“should do”或“do型”（be原形动词）虚拟语气。这类动词有：suggest，request，demand，urge，propose，prefer，advise，insist，require，order，command，ma

9、intain，ask，object 等。例如：The doctor suggested that he not go thereThe villagers demanded that their fields should be returned. The doctor insisted that the old teacher should live in hospital. The officer ordered that all the soldiers shouldnt fire before he gave the order. 2）宾语从句用在动词wish之后 I wish it

10、were trueI wish I could live on the moon one day. I wish you had called yesterdayI wish you had done the work yourself. I wish we had treated the children better. 3） 宾语从句在动词would，wouldhad rather，+did/ had done Id rather we didnt know each other. Id rather I hadnt given her the money yesterday. 【考点三、

11、虚拟语气在主语从句中的应用】 1）“It +is +形容词+that引导的主语从句”句型用于本句型的形容词有：necessary，important，surprising, shocking, natural, essential，reserved，urgent，impossible 等；It is necessary that he listen to the radio frequentlyIt is surprising that he should marry again soon after his ex-wife died. It is impossible that they s

12、hould feel uncomfortable to live with us. 2）用于“it + is +过去分词+that引导的主语从句”句型，用于本句型中的过去分词就是表示提议、要求、命令等动词的过去分词，如suggested，required，requested，demanded，urged，proposed，ordered，desired，advised等。It has been suggested that the meeting（should）be put off It is required that you should wear proper suits to take

13、 part in the party. It is desired that the prices of houses should be stopped from increasing.
