1、第七讲非谓语动词语法专题复习考点透析1.不定式、分词、动名词的否定式都是在其前面加not/never。例如:(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。例如:(1)Whenmother

3、修饰的名词是不定式动作的工具、地点,不定式后就应有必要的介词。例如:Therearefivepairstochoosefrom,butI'matalosswhichtobuy.4.不定式主动表被动的几种情况:在Therebe结构中,作定语的不定式既可用主动语态也可用被动语态。例如:Thereisalotofworktodo/tobedone.不定式作定语时,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作不定式的逻辑主语,不定式要用主动语态。例如:Wouldyoupleasegivetheboysomethingtoread?
4、(something是read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。例如:(1)Inthatcase,the

6、iate,can'thelp,consider,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作宾语。例如:(1)Ireallyappreciatehavingtimetorelaxwithyouonthisniceisland.(2)Theboywasluckyenoughtoescapebeingpunished.7.remember,forget,try,mean,regr
7、et,stop,goon后接不定式做宾语与接动名词作宾语,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努力做例如:(1)Shesearche
