should用在虚拟语气中吗

Answer 1

1．虚拟语气在条件句中的用法\x0d\x0a（1）若表示与现在事实相反的假设,则条件从句中用过去式,主句中用过去将来式（would,should,could,might + 动词原形）；若表示某事将来实现的可能性不大,则条件从句中用should + 动词原形也可用“were to+动词原形”或用过去式动词.如：\x0d\x0aI would certainly go if I had time．（现在）\x0d\x0aIf it should rain,we wouldn”t go out.（将来）\x0d\x0aIf I knew German,I would read the paper to you．（现在）\x0d\x0aIf he were here,we could ask him．（现在）\x0d\x0a（2）若表示与过去事实相反的假设,从句中用过去完成式,主句中用过去将来完成式（should,would,could,might + have + 过去分词）.如：\x0d\x0aIf I had set off a little earlier,I would have caught the train．\x0d\x0aShe would / might have come if she hadn”t been so busy．\x0d\x0aIf I hadn”t taken your advice,I would have made a bad mistake．\x0d\x0aIf only you hadn”t told him the news．\x0d\x0a（3）含有虚拟语气的条件状语从句中,如有had,should,were 这三个词的话,在正式或书面语言中可将if省略,再将句子的主语和谓语动词实行全部倒装或部分倒装.如：\x0d\x0aHad they time（=If they had time）,they would certainly come and help us．\x0d\x0aShould it be fine（=If it should be fine）,we would go for an outing．\x0d\x0aWere I go（=If I were you）,I would go．\x0d\x0a（4）若主句从句所指的时间不一致,即条件从句表示与过去事实相反,主句表示与现在事实相反；或者条件从句表示与现在事实相反,主句表真实情况,则从句中应采用与具体时间相对应的虚拟形式.如：\x0d\x0aIf it had rained last night（过去）,It would be very cold today（现在）．\x0d\x0aIf I had taken your advice（过去）,I should have no trouble with the work now（现在）．\x0d\x0a2．虚拟语气在宾语从句中的用法\x0d\x0a　　在动词suggest,order,demand,propose,request,command,insist等后的宾语从句中,用虚拟语气（即Should+动词原形或只用动词原形）来表示愿望、建议、命令、请求等.在动词wish /would rather后的宾语从句中,用过去式表示与现在事实不符,用过去完成式表示与过去事实不符.如：\x0d\x0aI suggest that we（should）set off at once．\x0d\x0aThe doctor insisted that the patient (should)be X-rayed．\x0d\x0aI wish I were as strong as you．\x0d\x0awould rather that you hadn”t told him．\x0d\x0a3．虚拟语气在主语从句中的用法\x0d\x0a　　　在It is necessary/important/strange/natural；It is requested/suggested/desired/proposed；it is a pity等结构后的主语从句中要用虚拟语气,即Should+动词原形或只用动词原形.如：\x0d\x0aIt is necessary that he（should）be sent there at once．\x0d\x0aIt is requested that Professor Li（should）give us a speech．\x0d\x0aIt is desired that we（should）get everything ready by tonight．\x0d\x0a4．虚拟语气在表语从句、同位语从句中的用法.\x0d\x0a　　在 suggestion,proposal,idea,plan,order,advice等名词后的表语从句、同位语从句中要用虚拟语气,即should+动词原形或只用动词原形.如：\x0d\x0aOur suggestion is that you（ should）be the first to go．\x0d\x0aMy advice is that we（should）send for Doctor Li．\x0d\x0aDo you know the order that you（should）keep watch?\x0d\x0a5．虚拟语气在其他状语从句中的用法\x0d\x0a　　在as if引导的状语从句中,用过去式表示与现在事实不符,用过去完成式表示与过去事实不符；在so that,in order that引导的状语从句中,常用should/would/could/might+动词原形来表示虚拟语气.如：\x0d\x0aThey talked as if they had been friends for years．\x0d\x0aShe stayed at home for a few days so that she could take care of her mother．\x0d\x0aHe took a taxi to the station so that she should not miss the train．\x0d\x0a6．虚拟语气在定语从句中的用法：\x0d\x0a在it is time后面的定语从句中常用过去式表示虚拟

英语中的一些命令性动词，如表示建议、请求、命令、主张等，在与之对应的从句中，可以使用虚拟语气。基本规则为：从句中的谓语动词用should接动词原形的形式，should可以省略，动词保持原形的形式。

这类动词主要包括：advise 建议；advocate 主张；arrange 达成协议；ask 要求；beg 恳求；commend 命令；decide 决定；decree 颁布命令；demand 要求；desire 希望；direct 指示；insist 坚决主张，坚决要求；instruct 指示，命令。

intend 打算；maintain 主张；move 提议；order 命令；prefer 宁可；prescribe 规定；propose 建议；recommend 建议；request 请求；require 要求；resolve 正式决定；suggest 建议；urge 督促。

例如：I suggest you (should) have enough sleep.

我建议你保证充足睡眠。

扩展资料：

除了上述命令性动词外，还有wish后接宾语从句，意思是“但愿，要是… …就好了”，表示不能实现的愿望时，谓语动词也用虚拟语气。

1、表示现在不能实现的愿望时，从句谓语动词用过去式。

例如：I wish I knew his telephone number.

我要是知道他的电话号码就好了。

2、表示过去不能实现的愿望时，从句谓语动词用“had+过去分词” 或“could+have+done”

例如：I wish you had come to the wdding.

你要是参加了婚礼就好了。

3、表示将来不能实现的愿望时，从句谓语动词用“would\might\could\should+do”

例如：I wish you could come to the party tomorrow.

我希望你明天来参加聚会。
