      動詞不定式的形式總結(jié)

        對于英語的學習中,關(guān)于動詞不定式的形式知識點的內(nèi)容,我們做下面的講解學習哦。

        動詞不定式的形式

        1.作主語。 如:

        To learn English is very important.

        但實際上不定式作主語常用 it來作形式主語,而將不定式移至謂語動詞后作真正的主語。

        如上句可表達為:

        It's very important to learn English.

        2.作表語。 如:

        My idea is to ring him up at once.

        3.作賓語。 如:

        I have decided to go to Binjiang Primary School.

        4.作賓語補足語。

        a. ask, want, teach, tell, know, would like, allow等動詞后面接動詞不定式作賓語補足語。

        如: The policemen asked him to get off the bus.

        b. hear, see, look at, feel, watch, notice, listen to等動詞后接不帶to的動詞不定式作賓語補足語。

        如: We often see Miss Li clean the classroom.

        c. let, make, have這些使役動詞后接不帶to的動詞不定式作賓語補足語。但在被動語態(tài)中這些不帶to的都須帶上to。

        如: In those days the bosses often made the workers work day and night.

        d.動詞help接動詞不定式作賓語補足語,可帶to也可不帶to。

        如: Can you help me (to) carry the heavy bag?

        5.作定語。

        a.與被修飾詞有動賓關(guān)系。如:I have something important to tell you.但如果不定式動詞為不及物動詞,后面的介詞千萬不要省略。

        如: Maybe they have three rooms to live in.

        b.與被修飾詞有主謂關(guān)系。

        如: Mr Liang is always the first to come and the last to leave.

        c.與被修飾之間只有修飾關(guān)系。

        如: I have no time to play cards.

        6.作狀語,表示目的、原因、方法、方向、結(jié)果等。

        如: I'll go to meet my friend at the railway station.

        7.不定式復合結(jié)構(gòu)"for sb. to do sth" 作主語時,常用"It is +adj+ for

        of sb. to do sth"的句式。形容詞good, bad, polite, unkind, kind, ice, clever,

        right, wrong, careful等用"It is +adj +of sb. to do sth."

        其他形容詞用 for。

        如:

        It's dangerous for you to ride so fast.

        It's very kind of you to help me.

        8.動詞不定式與疑問句who, what, which, when, how, where, whether等連用。

        如: I don't know when to start.

        He didn't tell me where to go.

        但上面結(jié)構(gòu)相當于一個從句,故上述句子也可表達為:

        I don't know when we'll start.

        He didn't tell me where he would go.

        注意:

        a.有些動詞或動詞短語不能帶不定式,只能接動詞的-ing形式。

        如: enjoy, finish, keep, mind, miss(錯過),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.有些動詞后可接不定式,也可接動詞的-ing形式,但意思不同。

        如: Lu Jian forgot to post the letter.(該寄但還沒做)

        Lu Jian forgot posting the letter.(已經(jīng)寄過信了)

        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)

        希望上面對動詞不定式的形式知識的內(nèi)容講解學習,同學們都能很好的掌握,相信同學們會取得很好的成績的哦。
