IF的虚拟语气怎么表达

2，if虚拟语气的用法

主句用一般过去时，从句用should do的形式，should 可以省略。

选a。这个就是主将从现的用法这个用在条件状语从句当中意思是：主句用一般将来时，从句从一般现在时(如果主句用过去将来时，则) 如果将你问句换为陈述句可以这么说 i will stay at home,if it rains tomorrow如果条件状语从句当中的时态不是一般现在时，那么一定是虚拟语气，应用完成时态

if虚拟语气的用法

3，if 虚拟语态

if 表示如果时它引导的句子是不是都要用虚拟语态？答：不是，不可实现是虚拟，可能实现不是虚拟。例如：如果我是你，我会这么做。（事实是我不是你，所以要用虚拟）虚拟语气一般是假设一种不可能实现的情况如果说：如果某样东西不属于你应该用真是条件句也就是说不用虚拟

你好！都用were仅代表个人观点，不喜勿喷，谢谢。

不一定，它引导条件状语从句时也表示如果，但不用虚拟语气。

原发布者:cyz091214如果上天能够再给我一次机会,我会对那个女孩说：“我爱你”。IfIhadonemorechance,Iwouldsaytothegirl“Iloveyou”.IfIhadonemorechance,Iwouldgotouniversityagain.虚拟语气定义：用来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，假设的语气叫虚拟语气。if引导的虚拟条件句Ifsheinvitedme,Iwouldgototheparty.假如她邀请我参加聚会，我就去。Ifshehadinvitedmeyesterday,Iwouldhavegonetotheparty.假如她昨天邀请我参加聚会，我就去了。Ifsheshouldinvitemetomorrow,Iwouldgotothepart如果她明天邀请我参加聚会，我会去的。1.对现在的虚拟if条件句中的谓语动词动词用过去形式(be动词用were)主句的谓语动词should/would/could/might+动词原形IfIwereyou,Iwould/could/should/mightdothat.IfIhadmoney,Iwould/could/should/mightbuythathouse.2.对过去的虚拟if条件句中的谓语动词haddone主句的谓语动词should/would/could/might+havedoneIfIhadknownthatyesterday,Iwould/could/should/mighthavetoldyou.Ifshehadnteatensomuchcandy,shewouldnthavehadherteethpulledout.3.与将来事实相反的假设if条件句中的谓语动词1.动词过去式(be动词用were)2.should+动词原形3.wereto+动词原形

should常用于第一人称和第三人称would表示结果might只表示可能性could表示能力、可能性、允许、虚拟语气常考错综句和wish+宾语从句、在wish宾语从句中不能should（警记）其余情况均分析句子意思、在适合情景用适应的词

有时你也可以选择用could或 might，但是如果是选择题的话肯定不能这些词都在选项里，那就又好几个答案了。没法选了。我做四级的时候就碰到过各种虚拟语气的题，比如有的要倒装，有的前半句用虚拟、后半句用真实语气。。。。这都要读懂题判断的、、、下面是总结。。你参考参考、1. 虚拟语气在if条件状语从句中的用法与现在事实相反：（从句谓语动词）动词的过去式(be用were而不用was) （主句谓语动词） should/ would /could/ might+动词原形与过去事实相反：（从句谓语动词） had + 过去分词（主句谓语动词） should/ would/could/might + have+过去分词与将来事实相反：（从句谓语动词）1.should+动词原形 2.动词过去式 3.were to+动词原形（主句谓语动词） should/ would/ could/ might +动词原形2. Wish 引导的宾语从句与现在事实相反：过去时（were）与过去事实相反： had+过去分词与将来事实相反： would/could/might+动词原形 eg. I wish I were a bird. I wish he hadnt done that. (do) I wish I would be rich in the future. 3. 表示要求,命令,建议的虚拟语气 Keys：1). insist 2). order, command 3). advise, suggest, and propose 4). demand, require, request, desire 这些动词后面的宾语从句要使用虚拟语气用法。即从句中的动词使用should + 动词原形, 或者省略should.直接家原形 eg. The doctor suggested that he (should) try to lose his weight. He insisted that we (should) tell him the news. 虚拟语气(二) the Subjunctive mood （假设语气）1. 表语从句、同位语从句中的虚拟语气在suggestion， proposal， order， plan， idea， advice， decision等需要有内涵的名词后面的表语从句、同位语从句中，要使用虚拟语气。其谓语动词应用：should＋原形动词。另外连接从句的that不能省略。 eg. My suggestion is that we should go there at once. What do you think of his proposal that we should put on a play at the English evening?2、 Its necessary/strange/natural/ important/pity/no wonder/impossible + that Clause 从句中的动词要用虚拟, 即(should)+动词原形 eg. It is strange that he (should) say so. 他居然会这样说，真是奇怪。 It is a great pity that you (should) think so. 他居然会这样想，真是一件憾事。 It is natural that a bird (should) rest in trees. 鸟在树上安歇是很自然的。3、在It is/was suggested /ordered / demanded / proposed / etc. 结构中要使用虚拟语气 eg. Its requested that we （should） keep the stability of the society for the peoples peaceful life. Its suggested that the plan be carried out. It is ordered that all the troops (should) withdraw three miles away. 根据命令，所有部队撤至三英哩以外。 It is arranged that he leave for Canada on Friday. 照安排，他星期五动身去加拿大。 It is suggested that the English evening be held on Saturday. 4. would rather 后的宾语从句。 eg. I would rather you could teach me again. The manager would rather that his secretary went to the meeting instead of him .经理宁愿他的秘书代替他去开会。5. as if， as though引导的从句。以as if 、as though（似乎，仿佛）引出的方式状语从，如果表示真实情况应该用直陈语气；如果表示非真实情况则应该用虚拟语气, 其谓语动词的虚拟式与wish后面宾语从句中谓语动词的虚拟式相同。 eg. The little boy knows so many things as if he was a man.6. 由if only （要是……，那该多好啊！）引导的惊叹句。如： If only I had passed the test ！比较if only与only if： only if表示"只有"；if only则表示"如果……就好了"。If only也可用于陈述语气。 eg. I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。 If only the alarm clock had rung.　　　当时闹钟响了，就好了。 If only he comes early.　　　　　　　但愿他早点回来。7. It is (high) time that It is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。 eg. It is time that the children went to bed. It is high time that the children should go to bed. It is high time that we had our lunch. 该是我们吃午饭的时候了。 It is time that he made up his mind. 该是他作出决定的时候了。

以as if (as though)引导的方式状语从句或表语从句，有时用虚拟语气，若表示与现在事实相反，谓语动词用一般过去时；若表示与过去事实相反，用过去完成时；表示将来的可能性不大，用would (might, could)+动词原形：he acts as if he knew me. 他显得认识我似的。they treat me as though i were a stranger. 他们待我如陌生人。he talks as if he had been abroad. 他说起话来好像曾经出过国。
