虚拟语气归纳总结

虚拟语气在主语从句、宾语从句等中运用
主语从句中虚拟语气的使用
当主语从句表达与事实相反的情况时,谓语动词用虚拟语气,其形式通常为“should + 动词原 形”或只用动词原形(美国英语)。
宾语从句中虚拟语气的使用
当宾语从句表达与事实相反的情况时,谓语动词也用虚拟语气,其形式与主语从句相同。
表语从句和同位语从句中虚拟语气的使用
忽略从句类型
定语从句分为限制性和非限制性两种,不同类型的从句在 使用虚拟语气时有所不同。如果在应该使用虚拟语气的从 句中忽略了这一点,就会导致语法错误。如:“The plan, which I suggest, should be carried out immediately.” (我建议的计划应该立即执行。)这个句子中,非限制性 定语从句“which I suggest”没有使用虚拟语气,因此是 错误的。正确的表达应该是:“The plan, which I suggest should be carried out immediately, is very important.”(我建议应该立即执行的计划非常重要。)
典型错误分析
误用虚拟语气
在非正式场合或口语中,有时会用虚拟语气表达强烈的愿 望或假设,但在正式书面语中,需要根据语境恰当使用。 如:“I wish I was a millionaire.”(我希望我是个百万 富翁。)这种表达在口语中常见,但在正式书面语中应改 为:“I wish I were a millionaire.”
忽略虚拟语气的特殊形式
在使用虚拟语气时忽略了其特殊形式,如 “should + 动词原形”或只用动词原形( 美国英语)。

英语虚拟语气知识点总结

英语虚拟语气知识点总结英语虚拟语气知识11、基础用法2. 注意四个情态动词的用法(1)若表示在某一假设的条件下,必然而然就会发生某事,第一人称可用should或would, 而二、三人称只用would.(2)若表示在某一假设条件下就能够干某事,各人称都用could.(3)如果表示在某种假设条件下有可能会发生某事,各人称都用might.3.虚拟语气的倒装当虚拟条件句中含有 were,had,should,could等动词时,可以将if省略,然后将 were,had,should,could等词移至句首。
注意:以上移至句首的 had不一定是助动词,如果是实义动词也可倒装:If he had money,he would buy a car. Hadhe money,hewould buy a car.(1)从句与过去事实相反相成,而主句与现在事实相反。
例如:If you had not been strict withme when I was young, I could not be such a successful person now.(这种虚拟语气的特点是主句中常含有时间准状语now或nowadays)(2)Should anyone come and ask for me, tell them I willcome back tomorrow.(主句为祈使句,条件句与将来事实相反,表示说话人认为某件事情发生的可能性很小。
)5.含蓄虚拟条件句含蓄虚拟条件句是指句中没有明显的虚拟条件句,而是利用其他手段来暗示存在虚拟条件。
这类用法主要见于以下七种方式:(1)将条件隐含在不定式短语中。
I should be happyto go with you. (=I should be happy if I could go with you.)(2)将条件隐含在分词短语中。
Born in bettertimes, he would have been a scholar. (=If he had been born in better times, he…)(3)将条件隐含在介词短语中。
高中英语语法-虚拟语气全总结

高中英语语法-虚拟语气全总结虚拟语气通常用于表达与现实相反的假设情况。
在非真实条件句中,虚拟语气的形式有两种:与现在事实相反的假设和与过去或将来事实相反的假设。
与现在事实相反的假设通常使用if+主语+助动词的过去式(如were。
did。
had)+动词原形,主句则使用XXX动词原形。
例如:If I had time。
I would XXX。
如果我有时间,我会参加会议。
与过去或将来事实相反的假设则有三种形式:①if+主语+动词过去式;②if+主语+wereto+动词原形;③if+主语+should+动词原形(注意不能是would)。
主句同样使用XXX动词原形。
例如:If you had taken my advice。
you would not have failed in the exam。
如果你听了我的建议,你就不会在考试中失败了。
在错综时间条件句中,动词形式要根据表示时间的状语从句作出相应的调整。
另外,在条件句中可以省略if,把were、had、should提到句首,变成倒装句式。
例如:Were I at school again。
I would study harder。
如果我还有上学的机会,我会更加努力研究。
Had you arrived earlier。
you would have caught the bus.If it rains tomorrow。
XXX climbing.What would you do with a n dollars?We couldn't have finished the work ahead of time without your help.Otherwise。
I would have taken part in the sports meeting.XXX me of your birthday。
or else I would have known nothing about it.A man who s drinking water would be dead in about seven days.I might have been XXX assistance。

2.错综时间虚拟语气 当从句与主句时间不一致时,动词的形式要根 据它所表示的时间作出相应的调整。 If you __ha_d__fo_ll_o_w_e_d__(follow)my advice just now, you __w_o_u_ld_b_e__(be)better now. If you __h_a_d_s_tu_d_ie_d_(study)hard before, you _w_o_u_ld_b_e_(be)a college student now.

1. 虚拟语气的概念
虚拟语气是用来表示一种不符合事实的假设或愿望等的语气。
它常用于两种情况:(1) 表示与事实相反的假设;(2) 表示某种虚拟的愿望或建议。
当我们表达出某个观点时,就可以使用虚拟语气。
2. 虚拟语气的类型
虚拟语气可以分为三类:条件句,虚拟愿望句和虚拟建议句。
(1)条件句是在一定条件下,让某种情况或结果可能发生的句子。
一般情况下,条件句中的谓语动词由“should+动词原形”或“were +动词原形”组成,以表示假定的事实。
例:If I were you, I would go and apologize to her.
(2)虚拟愿望句表示某一不可能实现的愿望,其谓语动词一般由“should+动词原形”构成,其句子结构为:“It+be+形容词/名词+that+主语+should+动词原形+其他”。
例:It would be nice if he should apologize to me.
(3)虚拟建议句是表示某种虚拟的建议,其谓语动词一般由“should+动词原形”构成,其句子结构为:“It+be+形容词/名词+that+主语+should+动词原形+其他”。
