动词的种类动词是表示动作或状态的词,按其词义和在句子中的作用可分为行为动词,连系动词,助动词和情态动词。
1.行为动词行为动词可分为及物动词(vt)和不及物动词(vi),及物动词表示动作或状态,有完整的词义,能单独作谓语,后跟宾语;不及物动词表示动作或状态,有完整的词义,能单独作谓语,但后面不能直接跟宾语,如要带宾语则与介词或副词构成短语。
如:More and more people study English.(vt)The students are listening to the teacher carefully.(vi)2.连系动词连系动词本身有一定的词义,但不能独立作谓语,必须与表语一起构成谓语。
常用的连系动词有be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。
如:Our country is becoming stronger and stronger.It feels damp.3.助动词助动词本身无词义,不能单独作谓语,只能和主要动词一起构成谓语动词,表示否定,疑问及动词的时态、语态、人称和数等语法特征,助动词有 be,do,have,shall,will等。

情态动词有can (could),may(might),must, need, ought to, dare等。

can只用于一般现在时和过去时,指本身有能力的"能";be able to用于各种时态均可,指须经过努力而"能"。

must表示说话人主观认为"必须",只用于一般现在时和一般将来时;have/has to表示客观需要,意为"不得不",它可用于各种时态。

初中英语语法大全:动词不定式的形式对于英语的学习中,关于动词不定式的形式知识点的内容,我们做下面的讲解学习哦。
动词不定式的形式1.作主语。
如:To learn English is very important.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.2.作表语。
如:My idea is to ring him up at once.3.作宾语。
如:I have decided to go to Binjiang Primary School.4.作宾语补足语。
a. ask, want, teach, tell, know, would like, allow等动词后面接动词不定式作宾语补足语。
如: The policemen asked him to get off the bus.b. hear, see, look at, feel, watch, notice, listen to等动词后接不带to的动词不定式作宾语补足语。
如: We often see Miss Li clean the classroom.c. 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不带to的都须带上to。
如: In those days the bosses often made the workers work day and night.d.动词help接动词不定式作宾语补足语,可带to也可不带to。
如: Can you help me (to) carry the heavy bag?5.作定语。
a.与被修饰词有动宾关系。
如:I have something important to tell you.但如果不定式动词为不及物动词,后面的介词千万不要省略。
如: Maybe they have three rooms to live in.b.与被修饰词有主谓关系。
如: Mr Liang is always the first to come and the last to leave.c.与被修饰之间只有修饰关系。
如: I have no time to play cards.6.作状语,表示目的、原因、方法、方向、结果等。
如: I'll go to meet my friend at the railway station.7.不定式复合结构"for sb. to do sth" 作主语时,常用"It is +adj+ forof sb. to do sth"的句式。
形容词good, bad, polite, unkind, kind, ice, clever,right, wrong, careful等用"It is +adj +of sb. to do sth."其他形容词用 for。
如:It's dangerous for you to ride so fast.It's very kind of you to help me.8.动词不定式与疑问句who, what, which, when, how, where, whether等连用。
如: I don't know when to start.He didn't tell me where to go.但上面结构相当于一个从句,故上述句子也可表达为:I don't know when we'll start.He didn't tell me where he would go.注意:a.有些动词或动词短语不能带不定式,只能接动词的-ing形式。
如: enjoy, finish, keep, mind, miss(错过),be busy, go on, keep on, be worth, practise等。
如: The peasants are busy picking apples.Would you mind my opening the door?b.有些动词后可接不定式,也可接动词的-ing形式,但意思不同。
如: Lu Jian forgot to post the letter.(该寄但还没做)Lu Jian forgot posting the letter.(已经寄过信了)They stopped to sing a song.(停止在做的工作而去做另一件工作)They stopped singing.(停止正在做的工作)希望上面对动词不定式的形式知识的内容讲解学习,同学们都能很好的掌握,相信同学们会取得很好的成绩的哦。
