1虚拟语气在英语文法中有三种语气，即直述式语气(IndicativeMood)、祈使语气(ImperativeMood)和虚拟语气(SubjectiveMood),其中前两种我们早已熟悉了，这里则不多谈了，女如 Howbeautifulsheis!则是直述式语气，而 Hurryup!Don'thurryup 则是祈使语气。我们主要来看看虚拟语气的主要用法。虚拟语气主要是用来表达一种无法实现的愿望，一种与事实相反的情况，或者将不可能实现的，或可能性很小的事实，假想为事实予以表述。这样的动词结构称为虚拟语气。它主要有三种形式，即与现在事实相反的假设，与过去事实相反的假设，与将来事实相反的假设。它们具体结构如表 8—7。虚拟语气的构成种类条件句结构主句结构与现在事实相反动词用过去式 be 动词用 wereShould/could+动词原形 would/might+动词原形与过去事实相反的用 had+过去分词Should/could+have+过去分词would/might+have+过去分词与将来事实相反动词用过去式 wereto 加动词原形 should 加动词原形should+动词原形 would+动词原形虚拟语气其他习惯用法简表种类功用句型例句主句谓语 宾语从句谓语动词 Iwishwecouldgototheseaside现在过去式today.过去had+过去分词IwishIhadgonetothebasketballmatch.虚拟语气表示主观愿望wish将来should+动词原形would+动词原形could+动词原形might+动词原IwishedIcouldflytothemoon.Iwishyouwouldstayherealittlelonger.wouldrather现在过去式Iwouldratheryoucametomypartytomorrow.表示虚拟比较或方 状语从句从句动词形式Shelookedaftertheorphanasifhewerehereownchild.2asif,asthough,evenif从句与现实相反过去式与过去相反had+过去分词They'retalkingasiftheyhadbeenfriendsformanyyears.与将来相反should+动词原形would+动词原形could+动词原形might+动词原Themanlookedworried,asthoughsomethingwouldhappentohim.that,sothat,inorderthat从句may+动词原形might+动词原形 can+动词原形could+动词原TurnonthelightsothatIcouldseeitclearly.Iwarnedhiminorderthathemightkeepawayfromthedanger.宾语从句用于suggest,propose,insist,desire,demand,request,order,command等之后(should)+动词原形TheyrequiredthatI(should)goatonce.Hesuggestedthatthemeeting(should)startearlier.表语从句主句中的主语常是：suggestion,idea,proposal,order,request 等Mysuggestionisthatweshouldtellhim.Ouronlyrequestisthatthisproblem(should)bes...
