非谓语动词,中考英语语法复习课件,一、定义 不充当句子谓语的动词叫做非谓语动词。它们不受主语限制，无时态与语态变化，又称非限定性动词。 二、形式 1. 动词不定式（to do sth. ） 2. 动名词（v. -ing） 现在分词（v. -ing) 3. 分词 过去分词（v. -ed或不规则变化）,考点一 动词不定式 动词不定式可作主语、表语、宾语、定语、状语和宾语补足语，我们主要掌握不定式作宾语、宾语补足语及目的状语的用法。,此外，不定式可以与疑问词连用, 用作主语、宾语、表语等。 I cant decide which one to buy. 我不能决定该买哪一件。（作宾语） When to start hasnt been discussed. 什么时候开始还没有被讨论。（作主语）,【温馨提示】 (1)help后接不定式时可以省略to； (2)有些动词后接不定式时通常省略to：feel, hear, see, watch, notice, let, make, have（简记为一感一听三看三让）。 上述动词变为被动语态后，其后的不定式必须补上“to”。,Tom helped his brother (to) learn to swim. 汤姆帮他的弟弟学习游泳。 变为被动语态：His brother was helped to learn to swim by Tom. We often hear Jack sing English songs. 我们常听见杰克唱英文歌。 变为被动语态：Jack is often heard to sing English songs.,【巧学妙记】只能跟不定式作宾语的动词 决心学会有希望（decide, determine, learn, wish, hope）, 同意计划莫假装(agree, plan, pretend), 胆敢拒绝会失败（dare, refuse, fail）, 准备设法来帮忙(prepare, try, manage, help), 提供请求负担起(offer, beg, demand, afford), 答应安排理应当（promise, arrange, be supposed）, 以上后跟不定式，劝君牢记永不忘。,考点二 动名词 动名词相当于名词、形容词。可作主语、宾语、表语和定语。,【巧学妙记】喜欢（enjoy)不断(keep)提建议（suggest) 盼望(look forward to)习惯(be used to)却完毕(finish) 想要(feel like)花费(spend)去练习(practice) 忍俊不禁(cant help)还介意(mind) 后接动词-ing My grandfather kept telling jokes and I couldnt help laughing. 爷爷不停地讲笑话，我忍不住笑了。,【温馨提示】 部分动词既可接动名词作宾语，又可接不定式作宾语，两者意义区别较大。 remember doing sth. 记得做过某事 remember to do sth. 记得去做某事（未做） forget doing sth. 忘了做过某事 forget to do sth. 忘了去做某事（未做） stop doing sth. 停止做某事 stop to do sth. 停下来去做某事,need doing sth. 需要做某事（被动含义） need to do sth. 需要去做某事（主动含义） try doing sth. 尝试做某事 try to do sth. 尽力做某事 hear/see sb. doing sth. 听见/看见某人正在做某事 hear/see sb. do sth. 听见/看见某人做了某事,考点三 分词 1. 分词的构成 分词分为现在分词和过去分词两种。现在分词由“动词+-ing”构成。过去分词的基本形式是“动词+-ed”，但也有不规则的形式。,2. 分词的句法功能,. 用所给词的适当形式填空 1.
