线话语法讲堂：动词不定式

线话英语|2015-05-11 16:44:01

　　动词不定式、分词(当初分词，从前分词)和动名词统称为非谓语动词。古代英语将当初分词和动名词合为一大类叫作v + ing形式。这些动词的形式不能在句中单独作谓语用，因而不语法主语。但可能有逻辑主语。因为没有语法主语，也就不受人称和数的限定，因为不是谓语，也就不时态和语态，但这些词仍能表示动作跟状态，所以仍有表现与其余动词相对时间关联的形式。由于与其它词有逻辑上的主谓关系，因此也有表示主、被动的情势，同时也有自己的宾语跟状语，一起构成非谓语动词的短语(动词不定式短语，分词短语，动名词短语)。非谓语动词在英语语法中占据特殊且重要的位置。非谓语动词形式多样，应用广泛，且在句中起着很活跃的作用，也是语法名目中的重点和难点，学好非谓语动词，才华正确进行书面语和书面的交流。内容来自

　　动词不定式、从前分词及v-ing形式在句中均不能作谓语用，所以叫做非谓语动词。

　　（一）动词不定式：

　　动词不定式由"to+ 动词原形"构成，如：to study, to play，动词不定式诚然不能作谓语动词用，但仍留着动词的特点，它能够带有所需要的宾语或状语而构成动词不定式短语，如：to study hard, to play table tennis。内容来自

　　 1、动词不定式的形式变更：动词不定式有下列时态和语态的形式变革。 CopyRight .com

　　语态式一般式实现式进行式完成进行式

　　主动 to build to have built to be building to have been building

　　被动 to be build to have been build

　　 2、动词不定式的基本用法：动词不定式能起名词、形容词和副词的作用，可在句中作主语、表语、宾语补足语、定语和状语用，如：

　　（1）作主语：To help each other is good.（动词不定式作主语时，正常可用it作形式主语，而将作主语的动词不定式置于句末，如：It is good to help each other.

　　（2）作表语：My job is to drive them to the power station every day. 动词不定式在系动词be之后作表语，与表示将来时的be + 动词不定式构造有所差异，如：Our plan is to set up another middle school for the peasants' children.咱们的盘算是给农夫子弟再成破一所中学。（句中的谓语动词为is，动词不定式to set up… 为表语，主语为plan，但plan并不是动词不定式的逻辑主语，即动词不定式 to set up所表示的动作不是主语plan发生的。）We are to set up another middle school for the peasants' children.咱们将为农民的后辈再成破一所中学。（句中的are to set up全体结构为句中谓语，主语为we，同时也是动词不定式to set up所表示的动作的逻辑主语，即动词不定式to set up所表示的动作是由we产生的）。内容来自

　　（3）作宾语：①作及物动词的宾语，如：She wishes to be a musician.；②作某些形容词的宾语：可以有动词不定式为宾语的形容词一般有glad, sorry, afraid, pleased, determined, willing, eager, anxious, ready, sure等，如：I am determined to give up smoking.；③动词不定式一般不作介词的宾语，但动词不定式之前如有疑问词时，就可作介词的宾语，如：Can you give us some advice on what to do next?

　　（4）作宾语补足语，如：Tell the children not to play on the street. 假如句中的谓语动词为see, hear, watch, notice, have, make, let等，作宾语补足语的动词不定式须将to省去，如：I saw a little girl run across the street.

　　（5）动词不定式在句中作宾语，如带有宾语补足语时，须先用it作形式宾语，而将该动词不定式后置，如：I don't think it right to do it that way. CopyRight .com

　　（6）作定语：动词不定式作定语时，须位于被其修饰的名词或代词之后，如：Is this the best way to help him? 和定语用的动词不定式如果是不迭物动词，不定式后面就要用必要的介词，如：He is the man to depend on. 如果被不定式润饰的名词为place, time, way，不定式后面的介词，习惯上可以省去，如：The old man is looking for a quiet place to live.

　　（7）作状语：动词不定式可以作下列的状语：①目的状语： Every morning he gets up very early to read English. 为了强调不定式表示目标的作用，可在不定式前加in order to或so as to（以便或为了），但应留心in order to位于句首或句中均可，而so as to不能位于句首，如：She reads China Daily every day in order to (so as to) improve her English. 将表示目的的不定式置于句首，也可强调目的的作用，如：To master a foreign language, one must work hard at it. ②成果状语：They lived to see the liberation of their home town.他们活到亲眼见到了他们家乡的解放。③too + 形容词或副词 + 动词不定式，表示"足能…"的结果，如：You are old enough to take care of yourself now.

　　 3、复合结构不定式：由for + 名词（或代词宾格）+ 动词不定式即构成复合结构的动词不定式。其中for本身无意思。for后面的名词或代词是不定式的逻辑主语，这种不定式在句中可作主语、表语、宾语、定语或状语，如：It is very important for us to get everything ready for the harvest. 当作表语用的形容词表示不定式的逻辑主语的性质或特色时，就用介词of而不用for引出不定式的逻辑主语，这些形容词个别有good, nice, kind, wise, silly, stupid, foolish, right, wrong, careless, impolite等，如：It is very kind of you to help him every day.

　　 4、疑难词 + 动词不定式：疑难代词和疑问副词后可加动词不定式形成不定式短语，在句中可作主语、表语或宾语，如：How to prevent them from swimming in this river is a problem. 内容来自

　　 5、动词不定式的否定式：动词不定式的否认式是由not + 动词不定式构成，如：It's wrong of you not to attend the meeting. CopyRight .com

　　 6、动词不定式的时态形式所表示的时光关系：（1）普通式：动词不定式个别式所表示的动作是和谓语动词所表示的动作同时发生，但在多数情况下，是在谓语动词所表示的动作之后发生，如：We decided to plant more trees this spring.（其后），They often watch us play table tennis.（同时）；（2）实现式：动词不定式完成式所表示的动作发生在谓语动词所表示的动作之前，如：I am sorryto have kept you waiting.（3）进行式：动词不定式进行式所表示的动作正在进行中，而且与谓语动词所表示的动作同时产生，如：She happened to be writing a letter in the room when I came in. CopyRight .com

　　 7、动词不定式的被动语态用法：如果动词不定式的逻辑主语为这个不定式所表示的动作的承受者时，不定式畸形就用被动语态形式，如：What is to be done next hasn't been decided yet.
