(或称实义动词)
连系动词
助动词
情态动词 see看见(vt.)
look 看(vi.) 及物动词(带宾语)
不及物动词(不带宾语be是 ,look看起来, seem似乎, get变得 ,become变成,sound...be; have; do; will...
如:He doesn't speak English.
We are playing basketball
Do you have a brother?can; many; must; need; dare; will; would; shall; should (后接v原形)
动词
(按其在
句中能
否作谓语)谓语动词
非谓语动词
动词分类(二):(在句中充当除谓语以外的其他句子成分的动词形式)动词不定式动名词分词动词不定式:.作主语。
如:?
(学好英语) is very important.
(早起床)is regarded as a good habit.
? ? To learn English well / Learning English well To get up early / Getting up early 动词短语作主语时,动词用动词不定式形式或v-ing形式(但实际上不定式作主语常用 it来作形式主语,而将不定式移至谓语动词后作真正的主语。
如上句可表达为:?
It's very important to learn English.作表语。 如:?
My idea is (给他打电话)at once.
My hobby is (看电视)?
to call him / calling himto watch TV / watching TV (动词短语作表语时,动词用动词不定式或V-ing 形式) 作宾语补足语 如:We often see Miss Li clean the classroom. ( hear, see, look at, feel, watch, notice, listen to等感官动词后接省to的动词不定式作宾语补足语,在被动语态中这些省to的都须带上to。)
= Miss Li is often seen to clean the classroom.(变被动语态).作宾语补足语。?
如: In those days the bosses often made the workers (日日夜夜工作)
work day and night. ( let, make, have这些使役动词后接不带to的动词不定式作宾语补足语。但在被动语态中这些省to的都须带上to)(变被动语态)=The workers were made to work day and night.如: You help me .
(动词help接动词不定式作宾语补足语,可带to也可不带to,但在被动语态中这些省to的都须带上to)
? (to) carry the heavy bag=I am helped to carry the heavy bag by you. It's dangerous you to ride so fast.?
It's very kind you to help me. 不定式复合结构“for sb. to do sth” 作主语时,常用“It is +adj+ for / of sb. to do sth”的句式。for of若adj.是描述行为者的性格或品质,则用of sb ; 若adj.仅仅是描述事物,不是对行为者品质的评价,则用for sbI don't know when we'll start.(改为简单句)
?
He didn't tell me where he would go.(同上) =I don't know when to start.=He didn't tell me where to go动词时态一、定义:
在英语中, 发生的
动作要用不同的动词形式来表
示,这每一种不同的形式就叫做时态。不同时间放学后我们经常打篮球.(昨天/ 明天/ 现在)
