B. 英語的不定式是什麼

不定式的定義是:在英語語法中,動詞不定式是指動詞中的一種不帶詞形變化從而不指示人稱、數量、時態的一種形式。它之所以被稱做不定式,是因為動詞不被限定,或者說不被詞形變化所局限。不定式屬於非謂語動詞形式。

對於英語來說接不定式的單詞多為「打算」「計劃」「希望」「將要做某事」等表示未來(未做的事)的動詞。同樣與不定式表示不同,現在分詞表示正在進行,一般性或經常性發生的行為。

(語態)動詞和參與此動作的主語之間關系的一個術語。當主語是動作的發起者(或之一)時,稱為主動語態,如果動詞不定式的邏輯主語是這個不定式所表示的動作的承受者,不定式一般要用被動語態形式。

(2)六年級英語不定式單詞擴展閱讀

不定式的形式:

1、現在式:一般現在時表示的動詞,有時與謂語動詞表示的動作同時發生,有時發生在謂語動詞的動作之後。一般為:動詞+ to do something。

2、完成式:表示的動作發生在謂語動詞表示的動作之前。

3、進行式:表示動作正在進行,與謂語動詞表示的動作同時發生。

4、完成進行式。

5、疑問詞who,what,which,when,where,whether,how後可接不定式構成不定式短語,在句中作主語、賓語、表 語等。

6、動詞不定式作主語時,句子的謂語動詞常用單數。

C. 英語動詞不定式

不定式的構成非常簡單,告訴我是什麼?對!是to+動詞原形。當然啦,to有時也可以不帶。動詞不定式沒有人稱和數的變化,可以擔當除謂語外的任何句子成分。那什麼時候 可以不帶to呢?

不定式省to有四種情況:

使役動詞 let,have,make 等後接不定式。如:Let him go! 讓他走!

would rather,had better後。如:You had better stay at home.你最好獃在家裡。

Why... / why not...後。如:Why not have a good rest on Sunday?為什麼星期天不好好休息一下呢?

感官動詞 see, watch, look at, hear, listen to, smell,feel, find 等後作賓補,省to。如:I saw him dance. 我看見他跳舞。注意:這些情況在被動句中可千萬不可省to喲! 如:The boss made them work the whole night.變成被動句:They were made to work the whole night.

不定式的特殊用法:

It與不定式:動詞不定式可以做主語,但如果動詞不定式太長,顯得頭重腳輕的,那麼我們就可用形式主語it代替,而把真正主語(即不定式)放於句尾。

如: It is not difficult for me to study English well.(對我來說學好英語是可能的。)不定式還可以充當句子的賓語,但有些動詞,如find,think,believe 等,這樣的不定式可繼續充當其賓語的作用。如: I found it difficult to fall asleep.我發現很難入睡。

還有一點:動詞不定式,還可用在how,when,where,what,which 等疑問代詞或副詞之後,與其共同作賓語。如:I don』t know how to use a computer.我不知道怎樣使用電腦。Remember?

too...to...和enough...to:too...to表達"太 ... 一致於不能..."。

enough ... to 表達 "足以..."。這兩個片語的用法用兩個例子就可以說清楚了。

The box is too heavy for me to lift.這個箱子太沉了,我提不動。

He is old enough to go to school.他到上學的年齡了。也就是說,他的年齡足夠上學了。記住這兩個句子就可以舉一反三,應用自如。

從兩道中考題看動詞不定式作定語

先看兩道中考題:

1.Who was the first one ____ ? A.to reach B.to arrive C.to get to D.to arrive at(2000山東濟南)(Key:B)

2.She has no paper ____ .A.to write B.to write with C.writing on D.to write on(2000重慶)(Key:D)

同是動詞不定式作定語,為何1題用了不及物動詞結構,2題卻用了不及物動詞加介詞結構?要回答這個問題,還得從動詞不定式作定語時與被修飾的成分(通常是名詞或代詞)之間所構成的邏輯關系說起。

動詞不定式作定語與被修飾的名詞或代詞在邏輯上常形成以下幾種關系:

一、主謂關系

被修飾成分是不定式所表示動作的發出者,即被修飾的成分為不定式邏輯上的主語。構成這種關系的動詞可以是及物的(其後應帶賓語),也可以是不及物的(其後無賓語)。例如:

1.The water to make steam is heated in a boiler.(相當於:The water makes steam...)產生蒸汽的水在鍋爐中加熱。

2.The next train to arrive was from New York.(相當於:The next train arrives...)下一列到站的火車是從紐約開來的。

二、動賓關系

被修飾的成分,從邏輯上看若是動詞不定式所表示的動作的承受者,即不定式與被修飾成分之間存在動賓關系,在這種情況下,動詞不定式動作的發出者往往是句子的主語泛指的「我們」、「人們」,此時該不定式中的動詞可以是及物的,但不可帶賓語;也可以是不及物的,但通常用「不及物動詞+介詞」結構。例如:

1.I have nothing to say on this question.(相當於:I』ll say nothing...)在這個問題上,我沒有什麼好說的。

2.He is the best man to consult with.(相當於:...consult with the best man.)他是可以商量問題的最合適的人。

註:當不定式所修飾的名詞是 place,day,way,time等時,該「不及物動詞+介詞」結構中的介詞可以省略。

1.Night was coming on and I had to look for a place to sleep.夜幕已開始降臨,我不得不找個睡覺的地方。

2.Carrie looked about for a place to seat and eat.嘉麗環顧四周,想找一個坐坐和吃飯的地方。

三、同位關系

不定式解釋或說明其所修飾成分的具體內容,這時被修飾的成分常常是抽象名詞(如:promise,attempt,decision,determination, will,willness,invitation,proposal,refusal,...)。此時,不定式中的動詞可以是及物的,也可以是不及物的。例如:

1.She lost her will to live.她失掉了生活的願望。

2.He made a firm resolution to give up smoking.他下了決心戒煙。

3.We gratefully accepted his promise to help us.我們感激地接受了他要幫助我們的承諾。

四、互相修飾關系

不定式修飾其前面的名詞,而不定式短語中的介詞又與該名詞構成介詞短語來修飾不定式(相當於狀語)。這種結構中的動詞可能是及物的(帶賓語),也可能是不及物的。例如:

1.I haven』t got a basket to carry apples in.(相當於:to carry apples in a basket)我沒籃子裝蘋果。

2.Having no work to go to and no family to provide for,he was free.(相當於:to go to work,to provide for a family)他無工作可做,也沒家庭可供養,他自由自在。

3.The old peasant gave me a sickle to cut rice with.(相當於:to cut rice with a sickle)那個農民給我一把鐮刀割稻子。

弄清了動詞不定式作定語時與被修飾成分存在上述四種邏輯關系,也就不難理解本文開頭的兩道考題:1題中的不定式與被修飾成分之間構成了主謂關系,且「到達」無對象,故用不及物動詞(arrive或get)來表達,因此選B;2題中的不定式與被修飾成分之間構成了動賓關系,且此處的write為不及物動詞,故該不定式用「不及物動詞+介詞」(...to write on)來表達,因此選D.

D. 背六年級下冊英語動詞不定式和過去式有什麼竅門

小妹妹,
不定式就是
to
+
動詞,
例如
:

to
find,
to
speak,
to
walk,
to
learn,
to
obey...etc.
所有動詞你能完全背念嗎
?

只要你能明白就好了.

過去版並不一樣,
你必權須死記,
不是靠背,
更要理解少許,
因每個動詞都有不同,
你自已分配好好讀之,
例如,


do
,
did
,
done
;
go
,
went
,
gone
;
cut,
cut,
cut
;
make,
made,
made
;

hit,
hit,
hit,
etc.

讀時要全記三個一起,
不要只記現在,
過去,
要加
完成時態.

E. 六年級英語四單元不定式和過去式

一般過去時:
句子結構:肯定句 主語+be(was,were)+其他 He was sick(生病) yesterday.
否定句 主語+be not+其他 He wasn't ill yesterday.
疑問句 Be+主語+其他 Were you ill yesterday?
或: 肯定句 主語+動詞的過去式+其他 例句:Mary stayed home last summer
否定句 主語+did not+動詞原型+其他 No, she didn't watch.
疑問句 Did+主語+動詞原型+其他 Did Mary watch television last weekend?
關鍵詞:yesterday,yesterday morning等 ,last week, last year, at the end of last term,
一段時間+ago如:ten years ago, five hours ago, on January 1st,2004, in the 1980s等。
Just now,in the old days, long ago, a moment ago注意動詞的過去式有兩種:一種是規則動詞的過去式;另一種是不規則的動詞不定式。所謂規則動詞不定式就是在動詞後面直接加ed,比如動詞stay,want等,它們的過去式就是stayed,wanted;而不規則動詞不定式就不能在動詞後直接加ed,比如:do,eat,sit等,它們的過去式分別為did,ate,sat等,沒有固定某種形式,這部分要經常練習,多看多記就不容易忘了

F. 英語中的單詞後面加不定式的規則是什麼

不及物動詞+不定式,不定式做狀語
如 go to play

及物動詞+不定版式,不定式做賓語權,如 want to eat an apple

It's very nice of you to help me. 你來幫助我,你真是太好了。

for 與of 的辨別方法:
用介詞後面的代詞作主語,用介詞前邊的形容詞作表語,造個句子。如果道理上通順用of,不通則用for。如:
You are nice. (通順,所以應用of)。
He is hard. (人是困難的,不通,因此應用for。)

I. 英語不定式

中文名來:動詞不定式
外文名:infinitive
在語法自中,動詞不定式是指動詞的一種不帶詞形變化從而不指示人稱、數量、時態的形式。它被叫做不定式,是因為動詞不被限定,或者說不被詞形變化所局限。不定式屬於非謂語動詞。

然而在一些語言里(例如葡萄牙語),存在著受時態、人稱和數量影響的不定式形態。亦有些語言完全沒有不定式,例如阿拉伯語、保加利亞語和現代希臘語。

在外語學習的課程中,動詞不定式的一般現在時被稱作「詞典用詞」,因為它一般被用作詞典中該動詞的詞頭。

對於英語來說接不定式的單詞多為「打算」「計劃」「希望」等表示未來的動詞。同樣與不定時表示不同的動詞不定式表示正在進行,一般性或經常發生性的行為。

動詞不定式可以作以上各種成分,但它畢竟是動詞,所以有動詞的屬性。

動詞不定式及其短語還可以有自己的賓語、狀語,雖然動詞不定式在語法上沒有表面上的直接主語,但它表達的意義是動作,這一動作一定由使動者發出。這一使動者我們稱之為邏輯主語。

J. 不定式英語單詞

1. 不定式定義:由to+動詞原形構成。 不定式是一種非限定性動詞。而非限定動詞是指那些在句中不能單獨充當謂語的動詞,可分為不定式,動名詞,現在分詞和過去分詞。
