）3）动词根据其后是否带有宾语，可分为两类，分别是：及物动词（Transitive Verb）、不及物动词（Intransitive Verb），缩写形式分别为vt.和vi.。

**英语动词是句子的核心。

它既决定着句子意思的表达同时又决定着句子的语法结构。

难怪有人说，英语是动词和介词的语言。

可见研究动词的用法在英语学习中是十分重要的。

(一、) 分清及物不及物:分清动词的及物不及物是在英语学习中必须解决的首要问题。

动词及物与不及物通常有以下几种情况：a．主要用作及物动词。

及物动词后面必须跟宾语。

可以用于："主＋谓＋宾"；"主＋谓＋双宾"；"主＋谓＋宾＋宾补"结构。

如：He reached Paris the day before yesterday.Please hand me the book over there.They asked me to go fishing with them.类似的还有：buy, catch, invent, found, like, observe, offer, prevent, promise, raise, find, forget, receive, regard, see, say, seat, supply, select, suppose, show, make, take, tell....b．主要用作不及物的动词。

非谓语动词非谓语动词是指那些在剧中不能单独充当句子位于成分的动词形式。

根本形式有四种：不定式〔infinitive〕、动名词〔gerund〕、分词〔participle〕、和独立主格结构〔absolute structure〕。

一、不定式动词不定式是非谓语动词中使用最广泛的一种，在句子中，它除了做谓语外，可以担当其他任何成分，可以做主语、宾语、表语、定语、状语、补语。

它在句中其名词、形容词举例：It isn’t cold enough for there to be a frost tonight, so I can leave Jim’s car out quite safely.He seems to be eating something.According to your market report, demand seems to be returning.The local health organization is reported to have been set up twenty-five years ago when Dr. Audio became its first president.不定式的语法功能：1) 作主语The traditional rule was that it’s safer (to stay where you are), but that’s been f undamentally inverted. The people who’ve been hurt the worst are those who’ve stayed too long.2) 作宾语Most journalists learn to see the world through a set of standard templates (patterns) into which they plug each day’s events.He feels it his duty to help others.3) 作表语But almost all have ignored the big, profitable opportunity in their own backyard: the wholesale food and drink trade, which appears to be just the kind of market retailers need.4) 作定语Tom made the decision to go around the world in three years all alone.She has the ambition to learn other languages.The pressure to compete causes Americans to be energetic, but it also puts them under aconstant emotional strain.5) 作状语A sad thing about life is when you meet someone and fall in love, only to find out in the end that you have wasted years on someone who wasn’t worth it.6) 作补语The man was seen to fall heavily to the ground and never get up again.注：使役动词如make、let、have等以及感官动词hear、see、feel、watch、notice等之后所加的不定式要省略to，但是在被动语态中不可省略。
