动词

一、什么是动词？表示动作或状态的词叫做动词。

二、动词的种类

按照动词的词义和动词在句子中所起的作用来划分，动词可分为五大类：

1.Be动词be动词很特殊，既可以作系动词又可以作助动词，而且用途广泛。

用法口诀：我用am，你用are，is跟着他她它，复数形式都用are。

2.实义动词实义动词也叫行为动词，能独立作谓语。如：

The lion opened its huge mouth and roared（咆哮）.

实义动词又可分为及物动词和不及物动词两类。

1）及物动词，后面可以直接接宾语。如：Judy found a Christmas gift in the stocking.

2）不及物动词，不需要宾语。如：The car stopped.

不及物动词后如跟宾语，须加上介词。如：listen to me

3）有些动词既可以作及物动词又可以作不及物动词。如：

play: play a game; play with yoyo.

4)有些动词既可以作及物动词又可以作不及物动词，但意义不一样。如：

ask: ask for help; ask him to go out

3.系动词系动词也叫连系动词，不能单独作谓语，必须和名词，形容词等一起使

用，作句子的谓语。常用的系动词有:

1）be动词（是最基本的系动词）如：I am from Hollywood.

2）五官动词：look, sound, smell，taste, feel 如：The boy looks very happy.

3）变化动词：get，become, turn等。如：The leaves turn green in fall.

4）状态动词：keep，stay等。如：Please keep quiet in the library.

4.助动词助动词有be；do, does, did; will(would) ,shall(should); have, has, had等。

它们和实义动词一起构成各种时态、语态，以及构成否定和疑问结构等。如：

The child is crying.

5.情态动词表示说话人的语气或情态。情态动词词义不完全，不能单独作谓语，

只能与动词原形一起构成谓语。情态动词有shall, should, will, would, can, could,

may, might, must, dare, need, ought to等。

动词的基本形式

动词原形就是在词典词目中所使用的动词形式。如：be do work live come like 2. 第三人称单数现在式的构成

1）变化口诀：s，es，y变i，have变has。

2）动词单三形式的发音规则

发音口诀：清清，浊浊，元浊，/t, d/后发/ts/ 和/dz/，遇到/s, z; t?, d? ; ?, ?；/发/iz/。

①当动词尾音为清辅音时，加s或es后发/s/: looks, helps, jumps

②当动词尾音为浊辅音或元音时，加s或es后发/z/：opens, airs

③当动词尾音为/t, d/ 时，加s后发/ts/ 和/dz/：cuts, needs

④当动词尾音为/s, z; t?, d? ; ?, ?/时，发/iz/：teaches, washes

3. 过去式和过去分词的构成

①当尾音为清辅音时，加ed后发/t/

looked, jumped, walked, washed, worked, asked, typed, watched, talked, thanked; helped;

②当尾音为浊辅音或元音时，加ed后发/d/

cleaned, opened, sharpened, turned on, listened ，aired;

③与单词尾音/t/一起构成/tid/：dusted, painted, waited, wanted, greeted;

与单词尾音/d/一起构成/did/: decided，needed

4. 现在分词的构成

四．有关“have”的必背词组：
