sing、dance、swim、play、talk、look等;

They left last week.

2、系动词(Linking Verb),连接主语和表语的动词称为系动词。不能独立存在 ,后面必须跟表语,表示主语的身份、类别、特征、状态等。如:

am、is、are、was、were、look、sound等;

He felt ill yesterday.

He was ill yesterday.

3、助动词(Auxiliary Verb),协助主要动词构成谓语的词叫助动词,如:

do、does、did、 done等;

He doesn\'t like to study.

Do come to my birthday party please.

4、情态动词(Modal verb)本身有一定的词义,但是不能独立作谓语,只能和动词原形一起构成谓语,如:

can (could), will (would), shall (should), may (might), dare (dared), must, need, ought to.

She may lose her way.

You can\'t carry the heavy box.

动词的第三人称单数

1、什么是第三人称单数?(The third person singular)

She brushes her teeth three times a day.

2、动词第三人称单数的变化规则,如:

动词现在分词的变化规则

现在分词(present participle),又称-ing形式,是分词的一种,表示主动或正在进行的动作,现在分词在句子里面不能单独充当谓语,是非谓语动词。

动词过去式的变化规则

动词的过去式(past tense)是在动词原形的基础上变化的,表示过去某个时间里发生的动作或状态。

I took a walk in the morning.

Eddle bought a bicycle three days ago.

动词过去分词的变化规则

过去分词(past participle)一般是由动词加-ed构成,表被动,动词过去分词的变化同过去式的变化规则,以下是不规则变化的几种情况:
