学习新单词对我来说非常重要。isveryimportantforme.

(2)用形式主语it,把真正的主语——动词-ing形式移置句尾。但这种句子形式有一定的限制,作表语的只能是某些形容词或少数名词,如:useful,useless,good,fun;nouse,worth。和他争辩是没有什么用的。isuseless.

跟你在一起工作是令人愉快的事。ispleasant.

归纳:常用-ing形式作主语的句型有:It+be+awasteoftimedoing...做……是浪费时间的。Itis/wasworth/worthwhiledoing...做……是值得的。Thereisnosenseindoing...做……没有道理。Thereis/wasnopointdoing...做……无意义。2.作宾语动词-ing形式作宾语有两种情况:一是有些动词只能后接动词-ing形式作宾语;二是有些动词后既可接动词-ing形式也可接不定式形式作宾语。(1)只能后接动词-ing形式作宾语的动词,常见的有avoid,consider,enjoy,keep,finish,suggest,dislike,risk,delay,escape,cannothelp,imagine,mind,miss,practice,cannotstand,putoff,giveup等。你是否考虑过找一位挚友?Haveyouonespecialfriend?

晚饭后你想和我一起散步吗?Doyouwithmeaftersupper?

(2)既可接动词-ing形式又可接不定式形式作宾语的动词(短语),常见的有:begin,start,continue,like,love,prefer,try,mean,forget,remember,hate等。①在动词forget,remember,regret之后,用动词-ing形式与不定式形式意义不同。动词-ing形式表示动作先于谓语发生,不定式形式表示后于谓语动作。我记得我已把信寄了。Iremember.

我会记着去寄信的。I’llremember.

我真后悔没赶上那次报告会。Iregret.

我遗憾地告诉你,我不能接受你的建议。IregretIcan’ttakeyouradvice.

②在try,mean之后,意义各不相同,如trytodo(设法),trydoing(试着),meantodo(打算,有意要做),meandoing(意思是,意味着)。我并不想让你生气。Ididn’tmean.

你的计划意味着要花费几个小时。Yourplanwouldmean.

③goondoing和goontodogoondoing继续做一直在做的事;goontodo接着做另外一件事。请接着做这同一个练习。Pleasegoonthesameexercise.

请做另外一个练习。Pleasegoontheotherexercise.

3.作介词宾语动词-ing形式可与介词一起构成介词短语(1)介词+动词-ing形式我向你道歉,刚才对你那样生气。Iapologizewithyou.

(2)动词+介词+动词-ing形式我坚持为这次出行带足需要的食物。2)Iinsistforthisexpedition.

下列短语中的to都是介词,所以后面跟名词或动词-ing形式:devoteto,objectto,payattentionto,getdownto,leadto,lookforwardto,stickto,beusedto等。巩固运用Ⅰ.翻译句子1.与他争论就是浪费时间。
