(非真实条件)(事实是The working conditions are too bad,、I won't accept the job)1-3 He said if he failed, he would have another try.他说他如果失败,他还会再试一次。
(真实条件)1-4 If he had failed, he would have had another try.如果他失败的话,他会再试一次的。
(非真实条件)(事实是He didn't fail and he didn't have another try.)二非真实条件句以被would所代替。
2.2 混合虚拟结构2.2.1不同时间的虚拟If he had listened to me, he would not be in trouble now.(从句与过去事实相反,主句与现在事实相反)If he had told me yesterday, I should know what to do now. (从句与过去事实相反,主句与现在事实相反)If I were you, I would have gone to her birthday party.

The bus left a moment ago.例题解析:The tree looked as if it ______ for a long time.A. hasn't wateredB. didn't waterC. hadn't bee wateredD. wasn't watered那棵树看上去好象很久没人给浇水了。
(答案是c)三含蓄条件句非真实条件句中的条件从句不出现if,假想条件只暗含在上下文中,这种句子叫做含蓄条件句。

3.2句中含有or, or else, otherwise, but等词语,暗示句子的某一部分(前句或后句)需用虚拟语气。
He was on business in Beijing at that ti me; otherwise he might have helped us。
Luckily Mary telephoned to inform me of the meeting, or would have been I absent。
I should have attended my friend’s wed ding ceremony, but I couldn’t afford the time。
四非真实条件句倒装省略连词if。
在书面语中,如果虚拟条件从句中有were,had 或should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。
If he had seen you yesterday,he would have asked you about it. →Had he seen you yesterday,he would have asked you about it.If I were you,I would do it at once. →Were I you,I would do it at once.Should he come (If he should come), tell him to ring me up.Were I you (If I were you), I would not do it. 我要是你,就不做这事。
Had he had lunch (If he had had lunch), he would not have eaten so many cookies.五宾语从句中的虚拟语气5.1下列动词后的宾语从句中insist(坚持),urge (催促),order(命令),command(命令),request(请求,要求),demand(要求),require(要求,需要)suggest(建议),advise(建议),propose(建议) , recommend(建议,推荐) 用(should ) +动词原形He suggested that we (should) save money for the future.The undergraduate insisted that he (should) go to work in the south.注意:当suggest表示暗示,insist表示坚持观点,事实时,后接的宾语从句应当用真实语气。
His silence suggested that he agreed with my decision.He insists that doing morning exercises does well to people’s health.例题详解:(1) “Shall I come tomorrow?” “I’d rather you _________.”A. won’tB. didn’tC. don’tD. wouldn’t(2) “I’ve told him about it.” “But I’d rather you _________.”A. didn’tB. hadn’tC. don’tD. wouldn’t(3) “He will take you as well.” “But I’d rather he _________.”A. won’tB. didn’tC. doesn’tD. wouldn’tB5.2 wish后接that宾语从句表示一种假想情况,实现可能性较小5.2.1对现在情况的虚拟,假想的情况与主句主语的愿望同时发生:宾语从句动词用过去式,谓语be用were。
例:I wish I knew the answer to the question.我希望知道这个答案。
(事实上是不知道)I wish it were spring in my hometown all the year around. 但愿我的家乡四季如春。
(事实上不可能)Now that he is in China, he wishes he understood Chinese.(wishes,过去虚拟动词understood)现在他在中国,他希望能懂得中文。
(事实上并不懂)5.2.2假想的情况在主句主语愿望前发生:宾语从句的谓语用过去完成时,例:I wish I hadn't wasted so much time.我后悔不该浪费这么多时间。
(事实上已浪费了)He wishes he hadn't lost the chance.他真希望没有失去机会。
(其实已失去)We wished he had spoken to us. (事实上他并没同我们讲)例题分析:I wish I ______ longer this morning, but I had to get up and come to class.A. could have sleptB. sleptC. might have sleptD. have slept动词wish后面接从句,表达不可能实现或与事实相反的情况时,谓语动词要用虚拟语气,即用过去式(表示现在发生的动作)或过去完成式(表示过去发生的动作)。
本题后半句谓语动词have用的是过去时had to get up and come, 所以前面要用过去完成时表示过去发生的动作。
所以, 选项A)could have slept是答案5.2.3假想的情况在主句主语愿望之后发生:从句谓语动词用would+原形动词I wish it would stop raining. 我希望雨能停止I wish you would be quiet. 我希望你安静一些。

英语语法精讲:虚拟语气学案,含习题,有答案
虚拟语气语气(mood)是英文中谓语动词的一种变化形式,用来表示说话者的意图和态度。
英文中的语气可分为三种:陈述语气(indicative mood),祈使语气(imperative mood)和虚拟语气(subjunctive mood)。
一、概述(一)虚拟条件句:两类三时两类:假设条件句、事实相反句三时:将来、现在、过去e.g. 1. If I were to have the time tomorrow, I would help him. (虚拟假设)2. If I had the time now, I would help him. (虚拟假设)If I were you, I would help him. (事实相反)3. If I had had the time yesterday, I would have helped him. (事实相反)总结:假设条件句表达的是一种在将来或现在可能性不大的情形,但不是不可能的情形,表示说话人认为不可能,是一种比较主观的表达。
事实相反句表达的是一种与现在或过去的事实相违背的情形,因此是不可能发生的。
正确使用虚拟语气的“四步骤”:是否虚拟;何时虚拟;主句虚拟;从句虚拟二、将来虚拟e.g. 1. If I were to live my life over again, I would have you as my wife.2. If I should win the lottery, I would buy a house.3. What do you think would be the value of the necklace, if I were to sell it?What do you think is the value of the necklace, if I sell it to you?4. If it were to rain, I would stay home.If it rains, I will stay home.总结:对于很多将来的情况,选择用虚拟还是不用虚拟,完全取决于说话人对所述事件的态度,或者说虚拟语气能表明说话人的态度。
