英語動詞分為及物動詞,不及物動詞,連系動詞,反身動詞,實義動詞,助動詞,限定動詞,非限定動詞和短語動詞.
1.及物動詞和不及物動詞：動詞根據(jù)它在句中是否跟賓
語,可分為及物和不及物,但是有的動詞既可以做
及物也可做不及物,比如fly
Boys fly kites(及物）
Birds fly(及物）
2.連系動詞：連系動詞表示不完全謂語關系的動詞,
它僅說明真正的謂語（既表語）在其后.
比如：
I am very hungry and tired(表語是形容詞）
He was a painter,a very bad one(表語是名詞）
常見的連系動詞有become,appear,get look,
remain,seem 等等.
3.助動詞分為時態(tài)助動詞和情態(tài)助動詞.
助動詞本身無實際意義或者意義不完全,不能單獨
做謂語.時態(tài)助動詞有：do,be,have ,shall
(should),will(would)等等.它們在句中和實義動
詞一起構成各種時態(tài),語態(tài),語氣以及否定和
疑問結構.比如：
Does he have coffee with his breakfast?
Do not be so careless.
The thief was caught in the parking lot.
4.情態(tài)動詞有shall,should,will,could would,
may,might,must,dare ,need,ought to 等等,
其用法與助動詞相同.比如：
you should have reported the matter to the
police.
I may have met him before.
You needn't come so early.
They dare not tell the truth.
