虚拟语气的用法，用虚拟语气翻译句子如果不是你的帮助我不可能按时完成工作 _语气

1，用虚拟语气翻译句子如果不是你的帮助我不可能按时完成工作 if_it_were_not_for_your_help,I_could_not_have_finished_the_work_on_time对将来的假设有2种。可能的就不用虚拟不可能或不太可能就用虚拟，比如如果我要成了亿万富翁。。。。如果我当了联合国秘书长。。。

2，虚拟语气中be动词一定用were吗对的，虚拟语气中，如果是be动词，就一定得用were，没有用was的情况哦，请及时采纳，谢谢如果是由was变化得到，应该改用were；其他情况如果用到be动词，还可以用should+动词原形的形式。不一定，were只限于使用在表示现在的虚拟语气中，而虚拟语气有三种：现在，过去，将来

3，would rather 后跟的虚拟语气我宁愿你现在不去想它would rather 后的虚拟语气句子里的动词本来就必须用过去式不是，would rather本身后面就是加DO原型的，但是这里，因为YOU做的事事过去式，所以本题用过去式。意思就是现在我宁愿你（当时）没有做这件事。for the time being是“目前”的意思，前面是现在时时后面用一般过去时来表示现在（前面是将来时时后面也用一般过去时）,前面是过去时时后面用过去完成时来表示过去的动作或状态我倒觉得你当前不必考虑它。对现在的虚拟，谓语要用过去时。我希望你不要想以后的事但实际上"你"肯定想了,所以用虚拟语气,现在时的虚拟用过去时要的，这句话的意思：我宁愿你不要考虑它。对现在的虚拟，谓语要用过去时【虚拟语气的用法，用虚拟语气翻译句子如果不是你的帮助我不可能按时完成工作】

4，虚拟语气的用法 1）虚拟语气概念虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。虚拟语气常在表示条件和结果的状语从句中。在表示与事实相反的虚拟语气时动词有三种时态：现在时，过去时，将来时。2）在条件句中的应用条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。常见虚拟语气用法1、真实条件状语从句与非真实条件状语从句eg .if he doesnt hurry up, he will miss the bus. ( 真实条件状语)（不是虚拟语气）if he was free, he would ask me to tell stories. （真实条件状语）（不是虚拟语气）if i were you, i would go at once. （非真实条件状语从句）if there were no air, people would die. （非真实条件状语从句）总结就是四个字：主将从现，主句用将来时，从句用一般现在时。2、虚拟语气在非真实条件状语从句中的用法及动词形式① 表示与现在事实相反的情况（条件）从句谓语动词形式主句谓语动词形式谓语动词用一般过去式（be用were） should/would/could/might+动词原形（过去将来时）eg.if i were you, i would take an umbrella.如果我是你，我会带把伞。（事实：我不可能是你）if i knew his telephone number, i would tell you. 如果我知道他的电话号码，我就会告诉你。（事实：不知道）if there were no air or water, there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水)if i had any money with me, i could lend you some. 如果我带钱了，我就会借给你些。（事实：没带钱）if he studied harder, he might pass the exam.如果他再努力些，就能通过考试了。（事实：学习不用功）②表示与过去事实相反的情况从句谓语动词形式主句谓语动词形式 had+过去分词（过去完成时） should/would/could/might+have+过去分词（现在完成将来时）（过去将来完成时）eg. if i had got there earlier, i should/could have met her. 如果我早到那儿，我就会见到她。（事实：去晚了）if he had taken my advice, he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话）③表示对将来情况的主观推测（可能相反或可能性很小）从句谓语动词形式主句谓语动词形式 if+主语+ ① should+动词② did③were to do(①通常与一个表示时间状语连用)其中were to do可能性最小，should/would/could/might+动词原形eg.if he would come here tomorrow, i should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。（事实：来的可能性很小）if there were a heavy snow next sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。（事实：不知能否下雪）if she were to be there next monday, i would tell her about the matter. 如果她下周一来这儿的话，我就会告诉她这件事得始末。在表示建议、命令、要求等含义的宾语从句，谓语动词常用虚拟语气，"should＋动词原形"构成，should 可省略。5，虚拟语气的用法Source: http://baike.baidu.com/view/26751.htm?fr=ala01）虚拟语气概念虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。虚拟语气常在表示条件和结果的状语从句中。在表示与事实相反的虚拟语气时动词有三种时态：现在时，过去时，将来时。2）在条件句中的应用条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。常见虚拟语气用法1、真实条件状语从句与非真实条件状语从句eg .If he doesnt hurry up, he will miss the bus.

If条件句中虚拟语气的用法,应特别注意省略if的倒装结构是考试的重点.4). would rather 等结构中虚拟语气的用法.5). if only结构中虚拟语气的用法.6). But, or, otherwise 等含蓄条件句的用法.7). Its time (that) 等结构中虚拟语气的用法.1. 虚拟语气在虚拟条件句中的运用(1)虚拟语气现在时.用以表示与现在事实相反的假设或现在实现可能性不大的情况.条件从句主句动词过去式(be多用were)Would/should/could/might + 动词原形Eg. If I were a bird, I would fly to you.If it were not for their help, we should be in a very difficult position.(2) 虚拟语气过去式.表示与过去事实完全相反的假设.条件从句主句had + 过去分词would/should/could/might + have +过去分词Eg. If we had started earlier, we should not have missed the train.If she hadnt been ill, she might have come.(3)虚拟语气将来式.表与将来情形相反的假设或极少有可能实现的情况.条件从句主句动词过去式或should +动词原形或were to +动词原形would/should/could/might +动词原形Eg. If Professor Li should have time tomorrow, we could ask him some questions.If there should be no air, there would be no living things.◆ 书面语中,上述(1),(2),(3)三种时态的虚拟句中,如果从句里含有should, had, were或其他助动词,则可将从属连词if省去,将助动词.情态动词.be或have放在句首形成部分倒装.Eg. Were he in your position, hed have done the same.Had I had time, I would have done that yesterday.Should he come tomorrow, I should give him the dictionary.(1)错综时间虚拟句通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的, 但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式.P 116, 2Eg. If I were you, I would have taken his advice. (从句指现在, 主句指过去)If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去,主句指现在).(2)含蓄条件句有时假设的情况并不以条件从句表示出来,二是暗含在上下文中,比如通过介词短语来表示.Eg. But for your advice, I could not have done it so successfully.The change could not have taken place without the open-door policy.I was so busy then, Otherwise, I would have told him the answer.(3)虚拟语气在某些从句中的应用.A)在wish, suggest, order, demand, propose, command, request, recommend, require, decide, insist, desire, urge等动词的宾语从句以及would rather /sooner 后要用 “ (should) +动词原形” 来表示愿望,建议, 命令,要求等; 由上述动词派生或转化的名词suggestion, proposal, plan, motion, recommendation, demand, order, desire, request, requirement, insistence, advice, decision , obligatory义不容辞的, 必须的等的同位语从句或表语从句中也要用相应的虚拟形式.Eg. B)在It is/was + 某些形容词 + that 从句的句型中,that从句中的谓语动词常用虚拟语气,即 “should + 动词原形” 这些形容词有:important, necessary, essential, imperative, natural, strange, advisable, desirable, possible, probable, astonishing, surprising, desired, suggested, requested, recommended, ordered, proposed, decided, moved等.“ should + 动词原形(或完成形式)” 可表示惊奇,遗憾,怀疑,不满等.ⅰ. 用于expect, believe, think, suspect 等动词的否定或疑问形式后的宾语从句中.Eg. I never expected that the new apartment should be so small.ⅱ. 用于 “It is a pity, it is a shame, it is no wonder 等 + that” 等结构后的主语从句中.Eg. It is a pity that he should be so careless.C)在由for fear that, in case, lest 等引导的状语从句中,用 “ should + 动词原形” 表示 “惟恐”的意思.Eg. He handled the instrument with care for fear that it should be damaged.D)在 “ It is (about/ high ) time + that (从句)” 中,谓语动词常用过去式表表示虚拟语气.Eg. It is high time that people learnt English.E)在 “as if/ as though” 引导的状语从句中,谓语动词与wish的宾语从句的虚拟形式相同.Eg. He works with such enthusiasm as if he never knew fatigue.He speaks English as though he were an American.F)在 look, seem等动词后的 “as if / as though”从句中,当表示真实情况时,用陈述语气; 否则,用虚拟语气.Eg. It seems as if they know each other. (真实情况)It seems as though it were already spring. (虚拟语气)G)用在if only 引起的感叹句中.Eg. If only the driver didnt drive so fast!虚拟就是if ....., sb would....if 后面不能用3W ：was would will例子if i were you, i would find a girlfriend.不能用wasif 从句永远不可能是事实。
