所谓的语气是指说话人对所指的动作或状态所持有的态度。和时态、语态一样，语气也是谓语动词的一种形式，表明说话人讲话的目的和意图。英语中有四种语气：陈述语气，疑问语气，祈使语气和虚拟语气。语气Mood１、陈述语气：陈述一个动作或状态，表示所说的是事实。Therearetwosidestoeveryquestion.２、疑问语气：用来提出问题，表示疑问。Isthisyourbook?３、祈使语气：表示讲话人对对方的请求、命令、号召、劝告、警告、禁止等。Don’tbelateforclass.Beseated,please.４、虚拟语气：用来表示假设、愿望、建议、请求、命令、猜测、可能、空想等非真实情况。句中的谓语动词需用一种特殊形式，称为虚拟语气。虚拟语气面面观DifferentfacesofthesubjunctivemoodFace1:虚拟语气在非真实条件句中１．表示与现在现实相反条件从句主句动词一般过去式（be常用were）would/should/could/might+动词原形Iftherewerenosubjunctivemood,Englishwouldbeeasier.IfIhadtimetospare,Iwouldcometoo.2.表示与过去事实相反条件从句主句had＋过去分词would/should/could/might+havedoneIfhehadbeenwarned,hewouldnothavetakenthatfood.Youdidn’tletmedrive.Ifwehaddriveninturn,youwouldn’thavegotsotired.3.表示与将来事实可能相反条件从句主句动词一般过去式should/could+动词原形wereto+动词原形would/should/could/might＋动词原形IfIknewhisaddress,Iwouldsendthelettertohim.Ifyouweretocometomorrow,Ishouldaskyoutohelpmewithmywork.Ifitshouldraintomorrow,Iwouldstayathome.条件从句主句与现在事实相反动词一般过去式（be常用were）would/should/could/might+动词原形与过去事实相反had＋过去分词would/should/could/might+havedone与将来现实可能相反动词一般过去式should/could+动词原形wereto+动词原形would/should/could/might＋动词原形Face2:虚拟语气在宾语从句中１．wishIwishIwereabird.HowIwishyouhadcometomybirthdayparty.IwishIcouldtryagain.现在过去将来动词的过去式be通常用werehad＋过去分词could/would/might+动词原形2.wouldratherI’dratheryouwenthomenow.Iwouldratheryouhadtoldmethetruth.3.用在suggest）建议（,advise,recommend,decide,require,request,demand,urge,propose,insist）坚持做（,command,order,ask,instruct）指示、命令（,prefer等表示提议、要求、命令、意愿、决定等意义的动词的宾语从句中，常用“should＋动词原形”表示虚拟语气，should常可省略。Hesuggestedthatweshouldputthemeetingoff.Sheurgedthathewriteandacceptthepost.Ourcommanderorderedthatallthewoundedsoldiersshouldbesenttohospitalatonce.Sheaskedthatsheshouldbesenttoworkinthecountryside.Iproposethathegotothemeetinginsteadofme.Heinsistedthatthismatterbetakenoveratthemeeting.【注意】使用insist,suggest等动词时，一定要注意，它们之后的宾语从句的谓语动词有时用陈述语气，有时用虚拟语气。当insist表示“坚持认为”“坚持观点”;suggest表示“表示、暗示、表明”时,后接的宾语从句用陈述语气。例如：IinsistedthatIwasright.Herpalefacesuggeststhatsheisnothealthy.Face3:虚拟语气在表语从句和同位语从句中在proposal,suggestion,order,requirement,desire,decision,advice,plan,necessity等名词后面的表语从句和同位语从句中，可用“(should)＋动词原形”表达虚拟语气。Hissuggestionisthatthemeeting(should)beputoff.Hemadethesuggestionthatthemeeting(should)beputoff.Face4:虚拟语气在主语从句中１．It+be+suggested/required/requested/demanded/…thatItisorderedthatwe(should)goatonce.Ithasbeeninstructedthatthemeeting(should)beputoff.2.It+be+necessary/essential/important/impossible/strange/natural/apity/…that…带有一种情感(必要、适当、惊奇、遗憾等)“竟然会”，从句中的should可以省略。◆Itisnecessarythathe(should)listentotheradiofrequently.◆ItisstrangethatheshouldnothavelearnedEnglish.◆Itisstranget...
