非谓语动词讲解

英语非谓语动词讲解及练习 非谓语动词是指分词（包括现在分词和过去分词）、不定式、动名词等三种形式，即：doing , done , to do , doing 。当然它们有各自不同的变化形式，如： 现在分词 doing : 有being done（被动式）; having done （完成式）; having been do ne （完成被动式） 不定式to do : 有to be done （被动式）; to have done （完成式）; to be doing（进行式）动名词doing : 有having done（完成式）; being done（被动式）; 非谓语动词的特点：三种非谓语动词都具有动词的特征，虽然它们没有人称和数的变化，但是它们都能带自己的状语或有时跟宾语。它们都有各自的特征：分词具有形容词和副词的特征；动名词具有名词的特征；不定式具有名词、形容词和副词的特征。具体来讲：分词在句子中可以做定语、表语、状语或补足语等；动名词在句子中可以做主语、宾语、表语等；不定式在句子中可以做主语、宾语、表语、补足语或状语。 下面分别对三种非谓语动词进行讲解： 一、动词不定式 先看几个例句，判断不定式在句中的成分。 1．To learn a foreign language is difficult . 2．His wish is to be a driver . 3．Tom wanted to have a cup of beer . 4．The teacher told us to do morning exercises . 5．I have nothing to say . 6．They went to see their aunt . 7．It’s easy to see their aunt. 8．I don’t know what to do next . 9．I heard them make a noise . 说明：1．动词不定式作主语, 2.动词不定式作表语,3.动词不定式作宾语,4．动词不定式作宾语补足语，5．动词不定式作定语,6．动词不定式作目的状语,7．动词不定式作真正主语，it 代替动词不定式，作形式主语。8．带有连接代词的动词不定式作宾语,9．不带to 的动词不定式作宾语补足语。 掌握动词不定式应注意的几个问题： 1．“to” 是不定式符号还是介词，下列短语中的to 都是介词。 agree to object to close to , come to , lead to , refer to , equal to , familiar to , point to , thank to , devote to , next to , belong to , be used to , look forward to 2．带to 还是不带to I have no choice but to give in I cannot do anything but give in I saw him enter the classroom . （但是：He was seen to enter the classroom .） 3．动词不定式逻辑主语是由for 作为标记的。但是有时用of . It’s necessary for you to study hard . It’s foolish of him to do it . 与of 连用的形容词有： good, kind , nice , wise ,clever , foolish , right , wrong , careful , careless , polite , possible

非谓语动词专题讲解

非谓语：（不能单独做谓语，但同时仍保留动词某些特征的动词形式。非谓语动词除了不能独立作谓语外，可以承担句子的任何成分。） 一、不定式与动名词做主语 1.动名词做主语往往表示普通的、一般习惯的行为，不定式做主语常表示某次具体的行为。 例句： Reading English is really a great fun.<这里不强调看一次，看两次……表示的是一般性的行为> To read english this morning will take most of my time.<这里用不定式表示一次具体的行为> 2.形式主语it 的运用: 1).不定式做主语,谓语用单数。往往用it做形式主语，把不定式放在谓语后面。 例句：To finish the job took us two hours. It took us two hours to finish the job. （注：在不定式做主语的被动语态句子中，必须用形式主语it.） 例句:it was decided to go for a picnic tomorrow. 2).It is+adj.of/for sb.to do sth.当不定式的逻辑主语和前面的形容词构成系表结构时，用of,否则用for. 例句： It’s very nice of you to help us.<此时，不定时的逻辑主语是you，adj.是nice,二者构成系表结构，即可以说you are nice.此时应该用of> It’s impossible for us to defeat the boss.<此时就不能说we are impossible.因此应该用for > 3).用动名词做主语的句型：It is/was no good(use, useless, fun)+doing sth. It’s worth while doing 例句： It’s no use cry over spilt milk.覆水难收 (it 用法远不止这几个后面会有补充) 3.成分对称：主语和表语都是非谓语动词时，应保持形式上一致。 例句： To see is to believe. Seeing is believing.眼见为实 4.There be no +ving 例句： There is no parking around here. No smoking,please. 练习题 It is hard_________ his mind.(to change ) It is fun__________ with a foreign man.(talking) There is no ________what will happen.(telling) I like_________ this novel this morning.(to read) 二：做表语 1.不定式做表语表具体个别的动作或有将来的含义。 例句：My wish is to become a famous writer. 2、现在分词做表语表示主语的性质与特征,表主动（interesting, amusing, disappointing, puzzling, exciting等）；进行时表示正在进行的动作。 例句： i am teaching the child to swim when you passed by.
