虚拟语气就是表示说话人的愿望、假设或建议，而不表示客观存在的事实。虚拟语气通过谓语动词的特殊形式来表示。
一. if引起的虚拟条件句
1：与现在事实相反,从句用一般过去时(be动词用were),主句用wuld/culd/might/shuld +d。If she had time, she wuld g with yu. If I were a bird, I wuld fly freely in the air.
2：与过去事实相反,从句用过去完成时,主句用wuld/culd/might/shuld have dne。If he had taken my advice, he wuld have succeeded in the cmpetitin.
3：与将来事实相反,从句谓语三选一：①一般过去时②were t d ③shuld d,主句用wuld/culd/might/shuld d。If it rained/were t rain/shuld rain tmrrw, we wuld nt g climbing.
4：错综条件句，即主句和从句与不同时间相反，则根据主从句位置和事实区别对待对号入座。If yu had fllwed my advice just nw, yu wuld be better nw. If yu were lder, I wuld have allwed yu t g there alne yesterday.
5：if条件句若省略if，则把were/ shuld/ had提前到句首构成部分倒装句。Were I yu (= If I were yu), I wuld g abrad at nce.Had I arrived (= If I had arrived) five minutes earlier, I wuld have caught the train.Shuld he cme (=If he shuld cme) tday, tell him t ring me up.
6：含蓄条件句，即句子含有withut, but fr, therwise等词，后面按主句对待。But fr the rain, we wuld have finished the wrk.I was ill that day. Otherwise, I wuld have taken part in the sprts meet. I wuld have delivered a speech, but I had a cld that day.
二、从句谓语用“(shuld)+动词原形”场合
1：一、二、三、四类动词(一坚持insist二命令rder, cmmand三建议advise, suggest, recmmend四要求demand, desire, require, request)接从句谓语用shuld+动词原形，且shuld可以省略。但应注意insist表示“坚持说”，suggest表示“暗示，表明”时，后接宾语从句应用陈述语气。
It is suggested that the meeting shuld be put ff till next week. The dctr rdered that the patient (shuld) be sent t hspital withut delay. The smile n his face suggested that he was satisfied with ur wrk.
2：一二三四类动词派生来的名词(rder, cmmand, advice, suggestin, requirement等)后接从句，该从句谓语动词用shuld+动词原形，且shuld可以省略。We agreed t the rder that the task (shuld) be cmpleted at 5 'clck.Our nly request is that this (shuld) be settled as sn as pssible.
3.It is necessary/strange/ 从句谓语用shuld+动词原形，且shuld可以省略。若从句涉及已经发生的动作，则应用shuld have dne。It is strange that he shuld have acted tward his parents like that. It's vital that we (shuld) take ur safety driving alng the rad seriusly.
三、特殊句型与虚拟语气
1：I wish that…从句与过去、现在、将来事实相反，分别用had dne, did, wuld/culd d。I wish that I were ten years yunger. I wish that I had met that film star yesterday.
2：if nly表示“如果……该多好”，as if/thugh表示“好像”，从句虚拟用法同上。He lks as if he were an artist. She lks as if nthing had happened t her.If nly I had seen the film with Jane last night.注意：as if /as thugh 也可用于陈述语气，表示谈论可能或真实的事情。如：It lks as if it’s ging t rain.
3：I wuld rather that…从句与过去事实相反用过去完成时，与现在、将来相反用一般过去时。（从句的谓语动词用过去时表对现在或将来虚拟，用过去完成时表对过去虚拟）I'd rather that he had gne t the seaside with me the day befre yesterday.When my father is upset, he wuld rather that we left him alne.
