1、非谓语动词(A、什么是非谓语动词?非谓语动词:就是不能做谓语的动词形式。主要是动词不定式和动名词。 B.主要形式:1.动词不定式:to+动词原型2.动名词:动词+ing.当然,情态动词can,must,may,系动词be,助动词be,do,does也不是能单独做谓语,单独时也是非谓语动词。C、用法在一个句子中,只有一个谓语动词,但是如果一个句子中出现多个动词时怎么办呢,如, I want to stop having a rest.我想停止休息。I want to stiop to have a rest.我想停下来,去休息。这两个句子中就出现了want stop have三个动词,那这就需要
2、只能保留一个谓语动词want. 那就在stop前加to ,在have前加to或have后去e加ing,这就把stop和have变成非谓语动词了。至于哪些动词后喜欢加动词不定式哪些词后喜欢加动名词,在这儿说几个重点的特别的动词用法:1、使役动词let,make, have后喜欢跟不带to的动词不定式,也就是动词原形,如: Lets play soccer.2、感官动词see,watch,notice,lookat,hear,listento,smell,taste,feel +do(也就是说这几个词后跟动词不定式时,喜欢把to去了)表示动作的完整性,真实性;当然这几个词后也能+doing表示动作
3、的连续性,进行性。 3、help这个词后接动词不定式时,to可要可不要。但要注意help和with构成短语时即help.with.时,with后要接动名词,因为with是介词。help+人+with sth /doing sth.4.want、ask、decide 、hope后喜欢加动词不定式。常见的有:wanttodosth. wantsb.todosth ask sb.todosth. decidetodosth lovetodosth. learntodosth. begintodosth wouldliketodosth wouldlikesb.todosth.Itstimetodos
4、th. somethingtoeat. Ihavemanythingstodo.5、 enjoy,、practise、finish、mind、spend后喜欢接动名词。注:再就是do some doing, go doing 句型 如:dosomecooking/cleaning/readinggoswimming/boating/shopping/fishing 6、 有些动词如stop、forget、remember、regret、like等后可接不定式和动名词,可接不定式或动名词时,意思差别很大。如: I must remember to post the letter.我必须记着要发信
5、。(信还未寄出) I remember posting the letter.我记得发了信了。(信已寄出)I like swimming.(喜欢游泳这项运动) I like to swim this Friday.(喜欢在星期五去游泳这一具体动作)I want to stop having a rest.我想停止休息(是指不休息了)。I want to stop to have a rest.我想停下来,去休息。(是指停止工作,去休息)注: 1、介词后接动词时一定用ing形式, 如:be good at swimming, help kids with singing, How/Whatabo
6、utdoingsth.?begoodatdoingsth.thankyoufordoingsth.2、 动名词做主语和表语例如:Swimmingismyfavoritesport.Myfavoritesportisswimming.3.祈使句中的动词用原形例如:Comehere.Dontgothere.)一、非谓语动词的定义及其形式1. 在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。它不受人称和数的限制。2. 非谓语动词的形式动名词:doing不定式:to do请看下列句子:I enjoy music.I enjoy listening to music.I want water.
7、I want to drink water.二、动名词和不定式作宾语1. 只能跟动名词作宾语的动词有:enjoy, finish, practice, mind, spend等。enjoy doing sth. 喜欢做某事finish doing sth. 完成做某事practice doing sth. 练习做某事mind doing sth. 介意做某事spenddoing sth. 花费.做某事口诀:喜欢完成练习,介意花费。e.g.He enjoys listening to the radio. 他喜欢听收音机。I have learned 200 Chinese words, but
8、 I keep forgetting some of them.我已经学了200多个汉字,但有些总是记不住。2. 只能接动词不定式作宾语的动词。在现行初中英语课本中动词有:decide, want, would like, plan, be used, refuse, help等。decide to do sth. 决定做某事want/would like to do sth. 想要做某事plan to do sth. 计划做某事be used to do sth.被用来做某事refuse to do sth. 拒绝做某事help to do sth. 帮忙做某事口诀:决定想要做计划,被人拒绝
9、不帮忙。e.g.He agreed to get someone to help us. 他同意找人来帮我们的忙。Mr. White wish to speak to you.怀特先生想要跟你讲话。3. 既能跟动词不定式也能跟动名词形式作宾语的动词有:like, love, begin , start, hate。在这种情况下,它们区别不大。Tomorrow I start to work(working). 明天我开始工作。Do you like to play(playing) football?你爱踢足球吗?但在下面情况下一般用动词不定式作宾语:would like /love后,表示特
10、定动作时。Would you like to leave a message?你要不要留个话儿?当谓语已经用了进行时态时。Its beginning to rain. 天开始下雨了。在begin后非限定动词由某些状态动词构成时。We began to think of this question. 我们开始考虑这个问题。She began to believe his story. 她开始相信他的故事。4动名词和动词不定式作宾语时意思不同的动词。(1) remember, forget, stop, go on, regret等动词后跟动名词作宾语时,表示动名词的动作发生在谓语动词动作之前;跟

12、topped to speak to Martin. 他停下来和马丁说话。(2) try和mean跟动名词和动词不定式作宾语时,在意思上差别很大。atry跟动名词作宾语时是“试着做某事”的意思;而跟动词不定式作宾语时是“设法做某事”的意思。试比较下面句子:She tried writing a composition. 她试着写作文。She tried to get you on the phone. 她设法打电话找你。bmean 跟动名词作宾语时是“意思是、意味着”的意思;而跟动词不定式时是“企图、打算”的意思。试比较下面句子:This means wasting much money. 这
