这里所说的动词是指各种动词总称，其中包括be动词、情态动词、助动词、行为动词（就是我们平时总说的那种动词）。
动词、名词和形容词不太容易区分，如不能一眼看出，可用如下方法：
先用一（量词）（如：一个、一张等）和这个词连起来说，如说得通，一般认为是名词；说不通再用很去判断，就是把很和为个词连起来说，说得通一般就是形容词；都说不通就是动词。（目前我们学过的，以后可能不同）（另外一些很明显的，如人称代词、数词、情态动词等一下就可以知道）
1、be动词（ am, is, are, was, were ）
1）am-was, is -was, are--were 口诀：我用am, 你用are, is用在他她它，所有复数全用are。
2）肯定和否定句 I am (not) from London. He is(not) a teacher. She is(not) in the dining room. My hair is(not)
long. Her eyes are(not) small.
3）一般疑问句 Am I a Chinese? Yes, you are. No, you arent. Are they American? Yes, they are. No, they arent.
Is the cat fat? Yes, it is. No, it isnt.
4）be动词的否定形式：am not（没有缩写形式），are not = arent ，is not = isnt 。
用恰当的be动词填空。

13）Here ______ some sweaters for you.

25）You, he and I ______ from China.
26）There _______ a boy, two girls, three men and ten women in the park.
2、助动词（ do, does, did ）
do, does用于一般现在时，其过去式did用于一般过去时。它们通常用在疑问句和否定句中。它们的否定形式：do not = dont, does not = doesnt, did not = didnt。
注意：在一般现在时中，does用于第三人称单数，其余一律用助动词do；助动词do, does, did后面一定要用动词原形。

3、情态动词
情态动词也是一类特殊的动词，平时我们不把它说成是动词。情态动词可以和行为动词同时出现在同一个句子中。
我们现在学过的情态动词有：can、could、shall、should、will、would、may、might 、must。
注意：情态动词后动词总是用原形。（不受其他任何条件影响）
其否定形式：can not = cant, must not = mustnt, 注意：may not和shall not（无缩写形式）

4、行为动词
就是我们平时上课时说的动词，表示某一动作或行为。如：sweep、live等。行为动词我们已学过它们的四种形式：原形、第三人称单数+s/es、现在分词（也叫动名词）+ing、过去式+ed。
（1）动词第三人称单数变化规则：
A、一般直接加s，如：play - plays, visit - visits, speak - speaks ；
B、以s，x，sh，ch结尾时，加es，如：catch - catches, watch - watches ；
C、以辅音字母+y结尾时，变y为i再加es，如：carry - carries, study - studies 。
（2）现在分词（动名词）构成规则：
A、一般直接加ing，如：go - going, do - doing, look - looking ；
B、以不发音的e结尾的单词，去e 加ing，如：take - taking, make - making, have - having ；
C、以重读闭音节结尾的词，如末尾只有一个辅音字母，需要双写这个字母再加ing，如：
put - putting, stop - stopping, run - running, get - getting, swim - swimming, sit - sitting, begin - beginning,
jog - jogging, forget - forgetting 。
（3）过去式构成规则：
A、一般直接加ed，如：plant - planted, visit - visited, pick - picked ；
B、以不发音字母e结尾，直接加ed，如：like - liked, hope - hoped, taste - tasted ；
C、以辅音字母+y结尾时，变y为i再加ed，如：try - tried, carry - carried, study - studied ；
D、有些动词要双写最后一个字母，再加ed，如：stop - stopped ；
