1、语法部分第八讲非谓语动词考点透析1.不定式、分词、动名词的否定式都是在其前面加not/never。如:(1)Mrs.Smithwarnedherdaughternevertodriveafterdrinking.(2)Notknowingwhattodo,Iwenttotheteacherforadvice.(3)Iapologizetoyoufornottellingyouthetruthimmediately.2.不定式的进行时表示动作与谓语动作同时发生。不定式、分词、动名词的完成式表动作在谓语之前发生。如:(1)Whenmothercamein
2、totheroom,Sidpretendedtobeworkinghardathislessons.(2)Robertissaidtohavestudiedabroad,butIdon,tknowwhatcountryhestudiedin.(3)Havingfinishedallmyhomework,IwentouttoplayfootballwithLiMing.(4)Theboywasseverelypunishedbyhisfatherforhavingtoldlies.3.不定式做定语时,如果不定式是不及物动词,或者不定式所修饰的名词是不定式
3、动作的工具、地点,不定式后就应有必要的介词。如:Therearefivepairstochoosefrom,butI,matalosswhichtobuy.4.不定式主动表被动的几种情况:在Therebe结构中,做定语的不定式既可用主动语态也可用被动语态。如:Thereisalotofworktodo/tobedone.不定式做定语时,如果不定式所修饰的名词是不定式的宾语,但是又可在句子中找到另一个词做不定式的逻辑主语,不定式要用主动语态。如:Wouldyoupleasegivetheboysomethingtoread?(something是r
4、ead的宾语,theboy是read的逻辑主语,不定式用主动语态。)注意比较下列两个句子:Ihavesomeletterstotype.(隐含意义:I,lltypethelettersmyself.)Doyouhaveanyletterstobetyped,sir?(隐含意义:I,lltypethelettersforyou.)5.关于不定式的省略在连词than,as后、介词except,but,besides后,如果前有实义动词do的某种形式,动词不定式一般不带to,反之则带to。如:(1)Inthatcase,thereisnothingyou
5、candothanwait.(2)Helikesreadingnovelsbesidestoplaythepiano.使役动词make,let,have和感官动词see,watch,hear,observe后接不定式做宾补时要省to,但在被动语态中,to不能省。如:(1)Acomputerdoesonlywhatthinkingpeoplehaveitdo.(2)Pauldoesn,thavetobemadetolearn.Healwaysworkshard.6.admit,advise,avoid,appreciate,can,thelp,consid
6、er,delay,deny,escape,enjoy,finish,feellike,fancy,imagine,mind,miss,practise,risk,suggest等动词以及所有带介词的短语动词后面只能跟动名词做宾语。如:(1)Ireallyappreciatehavingtimetorelaxwithyouonthisniceisland.(2)Theboywasluckyenoughtoescapebeingpunished.7.remember,forget,try,mean,regret,stop,goon后接不定式做宾语与接动名词做宾
7、语,意义有很大区别,必须牢记。regretdoing因做过某事而后悔,动作已发生;regrettodo因将做某事而遗憾,动作没发生;rememberdoing记得做过某事,动作已发生;remembertodo记得去做某事,动作没发生;forgetdoing忘记曾做过某事,动作已发生;forgettodo忘记做某事,动作没发生;meandoing意味着,meantodo打算做;stopdoing停止做,stoptodo停止做某事而做另一件事;trydoing尝试做,trytodo努力做。如:(1)Shesearchedthetopoftheh
