動詞的種類初中英語語法大全
關于英語中動詞的種類知識,希望同學們很好的掌握下面的內容學習。
動詞的種類
動詞是表示動作或狀態的詞,按其詞義和在句子中的作用可分為行為動詞,連系動詞,助動詞和情態動詞。
1.行為動詞
行為動詞可分為及物動詞 (vt)和不及物動詞(vi),及物動詞表示動作或狀態,有完整的詞義,能單獨作謂語,后跟賓語;不及物動詞表示動作或狀態,有完整的詞義,能單獨作謂語,但后面不能直接跟賓語,如要帶賓語則與介詞或副詞構成短語。
如:
More and more people study English.(vt)
The students are listening to the teacher carefully.(vi)
2.連系動詞
連系動詞本身有一定的詞義,但不能獨立作謂語,必須與表語一起構成謂語。常用的連系動詞有 be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。
如:
Our country is becoming stronger and stronger.
It feels damp.
3.助動詞
助動詞本身無詞義,不能單獨作謂語,只能和主要動詞一起構成謂語動詞,表示否定,疑問及動詞的時態、語態、人稱和數等語法特征,助動詞有 be,do,have,shall,will等。
如:
How do you usually come to school?
The children are playing yo-yo now.
4.情態動詞
情態動詞本身有一定的意義,但不能獨立作謂語,只能和主要動詞原形一起構成謂語,表示說話人的語氣和情態。情態動詞沒有人稱和數的變化。情態動詞有 can (could),may(might),must, need, ought to, dare等。
如:
Can I help you?
- Must we go now? -No, you needn't .
a. can與be able to的用法有所區別。can只用于一般現在時和過去時,指本身有能力的"能";be able to用于各種時態均可,指須經過努力而"能"。
b. must與have/has to的用法。must表示說話人主觀認為"必須",只用于一般現在時和一般將來時;have/has to表示客觀需要,意為"不得不",它可用于各種時態。
c.need和dare既可作情態動詞也可作行為動詞。
以上對動詞的種類知識的`內容講解學習,相信同學們已經能很好的掌握了吧,希望同學們在考試中取得很好的成績。
初中英語語法大全:動詞不定式的形式
對于英語的學習中,關于動詞不定式的形式知識點的內容,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系。
如: I have no time to play cards.
6.作狀語,表示目的、原因、方法、方向、結果等。
如: I'll go to meet my friend at the railway station.
7.不定式復合結構"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.
但上面結構相當于一個從句,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。
