虚拟语气-讲解版课件

虚拟语气Definition陈述语气（theIndicativeMood）用来陈述一个事实，或提出一个想法，有肯定、否定、疑问或感叹等形式。Thefishisnotalivewithoutwater.虚语语气（theSubjunctiveMood）表示说话人的一种愿望、建议、命令、要求、有时是一种非真实的假设、料想，或是不可能实现的与事实相反的愿望。1.虚拟语气的考点1、条件句中的虚拟语气的用法；2、条件句中虚拟语气的倒装；3、名词性从句中虚拟语气的用法；4、几种特殊结构中虚拟语气的用法；5、虚拟语气与陈述语气的判定。区别:Ifitrainstomorrow,thecropswillbesaved. 陈述语气

含蓄条件句

非真实条件句中的条件从句有时不表出来，只暗含在上下文中，这种句子叫做含蓄条件句。含蓄条件句大体有三种情况:

1.条件暗含在短语中。如：

WhatwouldIhavedonewithoutyou?(条件暗含在分词短语withoutyou中)

Itwouldbeeasiertodoitthisway.(条件暗含在不定式短语todoitthisway中)

Butforyourhelpwecouldn’thavesucceededintheexperiment.(暗含条件是butforyourhelp)

Thissamething,happeninginwartime,wouldleadtoadisaster.(条件暗含在分词短语happeninginwartime中)Hemusthavethestrengthofahippopotamus,orhenevercouldhavevanquishedthatgreatbeast.(暗含条件是连词or)Alone,hewouldhavebeenterrified.(暗含条件是alone)2.条件暗含在上下文中。如：Youmightstayhereforever.(可能暗含ifyouwantedto)

Wewouldhavesucceeded.(可能暗含ifwehadkepttrying)

Yourreputationwouldberuined.(可能暗含ifyoushouldacceptit)

Iwouldappreciatealittleofyourtime.(可能暗含ifyouweresokindastogivemealittleofyourtime)

3.在不少情况下，虚拟式已变成习惯说法，很难找出其暗含的条件。如：

Youwouldn’tknow.你不会知道。

Iwouldliketocome.我愿意来。

Iwouldn’thavedreamedofit.

这是我做梦也不会想到的。

Hetoldthestoryinsuchminutedetailthathemighthimselfhavebeenaneye-witness.

他将那事讲的非常仔细，简直就象他亲眼看见一样
