1、虚拟语气(1)编稿:牛新阁审稿:王春霞概念引入动词的语气表示说话人的态度和看法,可分为陈述语气、祈使语气和虚拟语气。1.陈述语气用来陈述事实或可能发生的事,有肯定、否定、疑问和感叹等形式。Aileenshowedgreatconcernaboutyou.艾琳很为你担心。(肯定)MylegsweresoweakthatIcouldhardlystand.我的腿软得简直不能站立。(否定)Wouldyoucaretocomeandstaywithmeovertheweekend?(疑问)你愿意来和我过周末吗?2.祈使语气用来提出请求、发出命令、警告、威胁、叮嘱、祝福、建议等。Enjoyyo
2、urselveswithyourtrip.一路愉快。(叮嘱)Don’tletthistypeofthingshappenagain.别让这种事再次发生。(警告)3.虚拟语气是说话人为表达一种假设,或一种主观愿望,即认为动词所表示的动作或状态并非真实或仅是主观设想时所用的动词形式。我们先看这些含虚拟语气的句子:1.Ifyouwereanartist,whatkindofpictureswouldyoupaint?2.Ifyoucouldhavethreeofthesepaintingsonthewallsofyourclassroom,whichwouldyouchoose?3.Ift

4、的宾语从句中的虚拟语气的用法。用法讲解if引导的虚拟条件句1.真实条件句与虚拟条件句:条件句分成两种,一种是真实条件句,一种是非真实条件句。真实条件句用陈述语气,所做的假设,说话人认为是可以实现的,或者与事实相符的;而使用虚拟条件句时,说话人知道所做假设与事实不符,或者很可能无法实现的。如:IfIhaveenoughmoney,Iwillgotothezoowithyou.如果我有足够的钱,我会和你一起去动物园。(暗含“我看看钱是否够,如果够我就去”)IfIhadenoughmoney,Iwouldgotothezoowithyou.如果我有足够的钱,我会和你一起去动物园。(暗含“我
5、事实上没有足够的钱,没法和你去”)2.虚拟条件句的构成:假设类型条件从句(if从句)谓语动词主句的谓语动词与现在事实相反一般过去式(be用were)would/should/might/could+动词原形与将来事实可能相反1)一般过去式(be只用were)2)wereto+动词原形3)should+动词原形would/should/might/could+动词原形与过去事实相反haddonewould/should/might/could+have+过去分词(注:与过去事实相反的用法将在下个单元学习。)IfIwereabird,Iwouldflyintothesky.如果我是只鸟,
6、我要飞向天空。(“我”不是鸟,也不能飞向天空,所以假设与现在事实相反,从句的be用were,主句用would+动词原形)Ifitweretoraintomorrow,themeetingwouldbeputoff.如果明天下雨,会议就会延期。(说话人认为明天不会下雨,要表示“与将来事实可能相反”,从句用wereto+动词原形,从句用would+动词原形,因为动词短语putoff与主语“会议”有被动关系,用beputoff)Iftherewerenogravity,weshouldnotbeabletowalk.假如没有地心引力,我们就不能行走。(事实:Thereisgravity.与
7、现在事实相反)Iwouldgotravelling,ifIhadlotsofmoney.如果我有许多钱,我会去旅游。(事实:Idon’thavelotsofmoney.与现在事实相反)Ifheshouldseeme,hewouldknowme.假如他看见我,就会认识我。(事实:Hewon’tseeme.与将来事实相反)IfitwereSundaytomorrow,Imightgotoseemygrandmother.(与将来事实相反)如果明天是星期天,我就
