英语语法之插入语完美课件

插入语在句子中插入一些单词、短语或句子，用来补充信息、作一些解释、表达说话者的看法、转移话题，或承上启下衔接句子，这些插入部分称为插入语。插入语是句子的附加成分，它与句子的其他成分无语法上的联系，通常用逗号或破折号与句子隔开，一般作独立成分。如果把插入语抽去，句子的含义不大受影响。简言之就是插话，不应该影响原句的含义。什么是插入语：（一）插入语的类型：1.副词或副词短语用作插入语：surely,certainly,generally,personally,fortunately,luckily,exactly,frankly,obviously,naturally,briefly,anyway,indeed,still,besides,however,otherwise,therefore,though,orrather等。Sheislookingfit,though.他看起来倒是健康。Ican,however,discussthiswhenIseeyou.2.形容词或形容词短语用作插入语：true，sureenough，worsestill，strangetosay，needlesstosay，mostimportantofall等。Peterwasafraidhehaddonebadlyonthetest，andsureenough,hisgradewasfailing.彼得生怕自己考不好。果然不出所料，他的分数不及格。Andneedlesstosay,Iwouldlovetobeofassistanceintranslatingthedata.不用说，我愿意协助翻译这些资料。3.介词短语作插入语：inaword,inafewwords,inall,intotall,inshort,inotherwords,inasense,ingeneral,infact,inaddition,inone'sopinion,asamatteroffact,asaresult,asaconsequence,ofcourse,forexample,bytheway,aboveall,ontheotherhand,onthecontrary,toone'sjoy,toone'ssurprise等。Alotofpeoplehere,forexample,Mr.Rogers,wouldratherhavecoffee.这儿的许多人，例如罗杰斯先生，宁愿喝咖啡。Ofcourse,hedidnotsucceedforthelackofexperience.当然，他由于缺乏经验而未成功。4.不定式短语用作插入语：tobesure,tobehonest,tobefrank,tobeshort,tobeexact,tosumup,totellthetruth,toputitbriefly/mildly,toconclude,tobegin/startwith,tomakealongstoryshort等。Tobesure,communityservicecanaidreemployment.毫无疑问，社区服务能有助于再就业。5.分词短语作插入语：generally/frankly/truly/strictlyspeaking,talkingof,including,judgingfrom/by,comparedto/with等。Judgingfromtheatmosphere,thestudentswereallhavingfunthen.从气氛来看，那些学生当时玩得很开心。6．陈述短句作插入语：Iamsure,I'mafraid,Ithink,Ihope,Iknow,Isuppose,Ibelieve,Isee,I/Theysay,Ibet,youknow,yousee,what'smore,what'sworse,whatisimportant,thatis(tosay),itseemstome,itissaid等。Thisyear,itissaid,wearegoingtohavewarmerwinter.据说今年冬天会比较暖和。YouknowthatIthinkyouarewrong.我认为，你明白你错了。Whatonearthdoyoumean?你究竟是什么意思？7.疑问短句作插入语：doyouthink,doyousuppose,doyouguess，doyouexpect，doyoubelieve等。其句型为“疑问词+doyouthink等+主语+动词？”Whodoyouthinkyou'retalkingto?你以为你在跟谁说话？Whatpresentdoyouexpectshehasgotforyourbirthday?你希望她给你带来什么样的生日礼物？Whydoyousupposetheaccidenthashappened?你认为事故为什么会发生？Howmanybooksdoyouguessheboughttheotherday？你猜他那天买了几本书？8.从句（有时是省略形式）作插入语:ifyoulike,ifyoudon'tmind,ifyouplease,ifImaysayso,ifnecessary,ifany,ifconvenient,ifnotbetterthan,asfarasIknow,asIseeit,asithappens等。Youcanusethedressingroomtheretotryiton,ifyoulike.如果您愿意的话，可以去那儿的试衣室试穿一下。Icouldcomeearlier,ifnecessary.如果必要我可以早点来。
