部分倒装中if引导虚拟语气的句式

if从句的虚拟语气原理： 1、如果句子在想象现在发生而实际未发生的事件，由现在时倒退成过去时： （从句）if+过去时，（主句）4个情态动词+动词原形 2、如果句子在想象将来发生而实际不会发生的事件，由将来时倒退成过去时，所以与1是一样的，但是此处从句有三种： （从句）if+过去时/if+were to do/if+should do，（主句）4个情态动词+动词原形 3、如果句子在想象过去发生而实际没有发生的事件，有过去时倒退成过去完成时： （从句）if+过去完成时，（主句）4个情态动词+have done 扩展资料 发音：英 [ɪf] ；美 [ɪf] 释义 1、conj. （表条件）如果；即使；是否；（表假设）假如 ①(表示条件)如果 ②(表示虚拟)假如,要是 ③(表示让步)即使 ④是否 ⑤(表示因果关系)每一次...的时候(总是会) 2、n. 条件；设想 参考资料：百度百科-if

1. 当if后面接一般现在时的动词时,表示对将来的一种推测. if sb do sth sb will/shall do sth. If you go with me, you shall be rewarded. 2. 当if后面接一般过去时的动词时,则是一种虚拟语气. if sb did sth sb would/should do sth. If I didn't make that mistake, I would't have suffered such a failure. 3. 当if后面接什么时态都可以时，if为“是否”的意思，句子为宾语从句. sb do sth if sb do sth. He said if rain was stop. 由if引导的条件状语从句，时态应该是主将从现，就是说主句用一般将来时，而从句用一般现在时表示将来。 例如 If it doesn't rain tomorrow, I will visit my former school. 这里从句就用一般现在时。 当然if引导的从句也可以用虚拟语气 例如If I got up early in the morning, I wouldn't miss the train.

if 引导的条件句中的虚拟语气 if引导的条件状语从句可以分为两类：真实条件句（sentences of real condition）和虚拟条件句。凡是假设的情况发生性可能很大，就是真实条件句；当假设是不大可能实现时，就是虚拟条件句。如： if i have time, i will help you with this work. 如果我有时间, 我会帮助你做的。 if time permits, we'll go fishing together. 如果有时间的话，我们就一起去钓鱼。 if i were you , i would have attended the meeting.我要是你的话，就去参加会议了。 if he had come here yesterday, he would have seen his old friend.假如他昨天来这儿的话，就会看见他的老朋友。 下面我们一起看看if在条件状语从句中的虚拟语气。 1. 表示与现在事实相反的情况。其句子结构为：从句：if + 主语+ 动词的过去式(be 用were) + ……主句：主语+ would (should, could , might) + 动词原形+ …… if i were you, i would read it again. 如果我是你的话，我再读一遍。（事实上我不是你） if he hurried, he could catch the first bus. 他要是快点能够赶上头班公共汽车。（可他不急） if she knew english, she would not ask me for help. 如果她懂英文，她就不必要我帮了。 2. 表示与过去事实相反的虚拟条件句。其句子结构为：从句：if + 主语+ had +过去完成式动词+ ……主句：主语+ would (should, could, might) + have +过去完成式动词+…… if you had taken my advice, you would not have made such a mistake.如果你听了我的劝告,就不会犯这样的错误。（事实上你没有听我的劝告） if it had rained yesterday, we would have stayed at home. 如果昨天下雨的话，我们就会留在家里。 if i hadn’t been ill yesterday, i might have come to school.昨天要是不生病，我是可能来上学的。（事实上我生病了） if you had studied harder last term, you could have passed the exam. 如果你在上个学期用功一些，你就会在考试中过关了。 3. 表示与将来事实相反的虚拟条件句 (对将来的事实实现的可能性不大)。其句子结构为：从句：if + 主语+ should (或were) + 动词原形+……主句：主语+ would (could, should, might) + 动词原形+…… if it should rain tomorrow, i would stay at home. 如果明天下雨的话，我将待在家里。（根据天气情况，明天不可能下雨） if he came tomorrow, i would do it with him. 如果明天他来的话，我将和他一起做此事。（事实上他来的可能性很小） if he were here, i would give him the books. 如果他在这儿，我可能会把书给他。
