初中英語(yǔ)常用動(dòng)詞不定式的短語(yǔ)歸納 篇2
對(duì)于英語(yǔ)的學(xué)習(xí)中，關(guān)于動(dòng)詞不定式的形式知識(shí)點(diǎn)的內(nèi)容，我們做下面的講解學(xué)習(xí)哦。
動(dòng)詞不定式的形式
1．作主語(yǔ)。 如：
To learn English is very important.
但實(shí)際上不定式作主語(yǔ)常用 it來(lái)作形式主語(yǔ)，而將不定式移至謂語(yǔ)動(dòng)詞后作真正的主語(yǔ)。
如上句可表達(dá)為：
It's very important to learn English.
2．作表語(yǔ)。 如：
My idea is to ring him up at once.
3．作賓語(yǔ)。 如：
I have decided to go to Binjiang Primary School.
4．作賓語(yǔ)補(bǔ)足語(yǔ)。
a. ask, want, teach, tell, know, would like, allow等動(dòng)詞后面接動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。
如： The policemen asked him to get off the bus.
b. hear, see, look at, feel, watch, notice, listen to等動(dòng)詞后接不帶to的動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。
如： We often see Miss Li clean the classroom.
c. let, make, have這些使役動(dòng)詞后接不帶to的動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。但在被動(dòng)語(yǔ)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(dòng)詞help接動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)，可帶to也可不帶to。
如： Can you help me (to) carry the heavy bag?
5．作定語(yǔ)。
a.與被修飾詞有動(dòng)賓關(guān)系。如：I have something important to tell you.但如果不定式動(dòng)詞為不及物動(dòng)詞，后面的介詞千萬(wàn)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(yǔ)，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(fù)合結(jié)構(gòu)"for sb. to do sth" 作主語(yǔ)時(shí)，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(dòng)詞不定式與疑問(wèn)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(dāng)于一個(gè)從句，故上述句子也可表達(dá)為：
I don't know when we'll start.
He didn't tell me where he would go.
注意：
a.有些動(dòng)詞或動(dòng)詞短語(yǔ)不能帶不定式，只能接動(dòng)詞的`-ing形式。
如： enjoy, finish, keep, mind, miss(錯(cuò)過(guò)),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(dòng)詞后可接不定式，也可接動(dòng)詞的-ing形式，但意思不同。
如： Lu Jian forgot to post the letter.(該寄但還沒(méi)做)
Lu Jian forgot posting the letter.(已經(jīng)寄過(guò)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(duì)動(dòng)詞不定式的形式知識(shí)的內(nèi)容講解學(xué)習(xí)，同學(xué)們都能很好的掌握，相信同學(xué)們會(huì)取得很好的成績(jī)的哦。
初中英語(yǔ)常用動(dòng)詞不定式的短語(yǔ)歸納 篇3

連系動(dòng)詞后可以接to be嗎
The story sounds __________.
A. to be true B. as true C. being true D. true
此題應(yīng)選D。該題很容易誤選A。這里涉及連系動(dòng)詞后是否接to be的題：
1. 在seem，appear，prove，continue等連系動(dòng)詞以及用作連系動(dòng)詞的短語(yǔ)turn out等之后，可以接to be，但可省略：
He seems (to be) sad. 他似乎很傷心。
He appears (to be) angry. 他似乎生氣了。
The news turned out [proved] (to be) false. 那消息結(jié)果是假的。
2. 在feel，smell，sound，taste等連系動(dòng)詞后不接to be：

正：The soup tastes nice.
誤：The soup tastes to be nice.
在look(看起來(lái))之后是否接to be，語(yǔ)法專家意見(jiàn)不一，但總的說(shuō)來(lái)，以不用為佳。
3. 在表語(yǔ)形容詞前的to be通常不省略：
He seems [appears] to be asleep. 他似乎睡著了。
He seemed to be awake when I went into his room. 我進(jìn)屋時(shí)，他似乎醒了。

初中英語(yǔ)動(dòng)詞的分類及基本形式講解
關(guān)于英語(yǔ)動(dòng)詞的分類及基本形式知識(shí)，我們做下面的內(nèi)容講解學(xué)習(xí)。
英語(yǔ)動(dòng)詞的分類及基本形式
動(dòng)詞的分類
表示動(dòng)作中狀態(tài)的詞叫做動(dòng)詞。根據(jù)其在句中的功能，動(dòng)詞可分為行為動(dòng)詞、系動(dòng)詞、助動(dòng)詞和情態(tài)動(dòng)詞四類，有些動(dòng)詞是兼類詞。如：
We have lunch at 12. 我們12點(diǎn)吃午飯。(have是行為動(dòng)詞)
We have been to New York. 我們?nèi)ミ^(guò)紐約。(have是助動(dòng)詞)
W I am hungry. 我餓了。(am是連系動(dòng)詞)
She was beaten on the way home. 她在回家的路上被人打了。(was是助動(dòng)詞)
You needn’t have waited for me. 你本來(lái)不必等我。(need是情態(tài)動(dòng)詞)
The door needs painting. 這個(gè)門需要油漆了。(needs及物動(dòng)詞)
動(dòng)詞的基本形式
絕大多數(shù)動(dòng)詞都有五種基本形式：動(dòng)詞原形、一般現(xiàn)在時(shí)第三人稱單數(shù)、過(guò)去式、過(guò)去分詞和現(xiàn)在分詞。
A. 第三人稱單數(shù)形式的構(gòu)成
一般現(xiàn)在時(shí)主語(yǔ)是第三人稱單數(shù)時(shí)，謂語(yǔ)動(dòng)詞后要加s或es，其變化規(guī)則與名詞變復(fù)數(shù)的方法大體相同：
1. 一般情況下只在動(dòng)詞后加s，如work—works, write—writes。
2. 以s, x, sh, ch結(jié)尾的動(dòng)詞，后加es，如guess—guesses, mix—mix, finish—finishes, catch—catches。
3. 以輔音字母加y結(jié)尾的動(dòng)詞，改y為ies，如study—studies。
注：不規(guī)則變化的有have—has, be—is, go—goes, do—does等。
B. 現(xiàn)在分詞的構(gòu)成
1. 一般情況下在動(dòng)詞后加ing，如study—studying, work—working。
2. 以不發(fā)音的字母e結(jié)尾的動(dòng)詞，先去掉e再加ing，如write—writing, move—moving。
3. 以一個(gè)元音字母和一個(gè)輔音結(jié)尾的重讀音節(jié)結(jié)尾的動(dòng)詞，要雙寫(xiě)末尾一個(gè)輔音字母，再加ing，如get—getting, begin—beginning。
4. 以ie結(jié)尾的名詞，一般將ie改為y，再加ing，如lie—lying, die—dying, tie—tying。
注：(A) 以l結(jié)尾的動(dòng)詞，尾音節(jié)重讀時(shí)，雙寫(xiě)l，如control—controlling；尾音節(jié)不重讀時(shí)，雙不雙寫(xiě)都可以，如travel—traveling(美) /travelling(英) 。(B) 特例：picnic—picnicking。
C. 過(guò)去式和過(guò)去分詞的構(gòu)成
1. 一般情況直接加ed，如ask—asked, work—worked。
2. 以不發(fā)音的e結(jié)尾，只加d，如love—loved, dance—danced。
3. 以輔音字母加y結(jié)尾，把y變?yōu)閕ed，如try—tried, study—studied。
4. 以一個(gè)元音字母和一個(gè)輔音結(jié)尾的重讀音節(jié)結(jié)尾的動(dòng)詞，先雙末尾一個(gè)字母，再加ed，如stop—stopped, permit—permitted。
注：(A) 以l結(jié)尾的動(dòng)詞，尾音節(jié)重讀時(shí)，雙寫(xiě)l，如control—controlled；尾音節(jié)不重讀時(shí)，雙不雙寫(xiě)都可以，如travel—traveled(美) /traveled(英) 。(B) 特例：picnic—picnicked。另外，還有很多動(dòng)詞的過(guò)去式和過(guò)去分詞是不合乎上述規(guī)則的，需要熟記。
以上對(duì)英語(yǔ)動(dòng)詞的分類及基本形式知識(shí)的講解學(xué)習(xí)，同學(xué)們都能很好的掌握了吧，相信同學(xué)們對(duì)英語(yǔ)的學(xué)習(xí)是很有信心的吧。
初中英語(yǔ)情態(tài)動(dòng)詞的語(yǔ)法特征講解
下面是對(duì)英語(yǔ)中，關(guān)于情態(tài)動(dòng)詞的語(yǔ)法特征的內(nèi)容講解，同學(xué)們認(rèn)真學(xué)習(xí)并很好的掌握下面的內(nèi)容哦。
情態(tài)動(dòng)詞的語(yǔ)法特征
1） 情態(tài)動(dòng)詞不能表示正在發(fā)生或已經(jīng)發(fā)生的事情，只表示期待或估計(jì)某事的`發(fā)生。
2） 情態(tài)動(dòng)詞 除ought 和have 外，后面只能接不帶to 的不定式。
3） 情態(tài)動(dòng)詞沒(méi)有人稱，數(shù)的變化，即情態(tài)動(dòng)詞第三人稱單數(shù)不加-s。
4） 情態(tài)動(dòng)詞沒(méi)有非謂語(yǔ)形式，即沒(méi)有不定式，分詞，等形式。
希望上面對(duì)英語(yǔ)情態(tài)動(dòng)詞的語(yǔ)法特征知識(shí)的講解學(xué)習(xí)，同學(xué)們都能很好的掌握，相信會(huì)給同學(xué)們的學(xué)習(xí)很好的幫助。
初中英語(yǔ)語(yǔ)法之Be動(dòng)詞定義及用法講解
對(duì)于英語(yǔ)中Be動(dòng)詞定義及用法知識(shí)的學(xué)習(xí)，希望同學(xué)們很好的掌握下面的講解的知識(shí)。
Be動(dòng)詞定義及用法
1. Be動(dòng)詞有三個(gè)，am,is還有are.我用am, 你用are, is跟著他她它，復(fù)數(shù)全部都用are.
如果遇到過(guò)去時(shí)，was來(lái)把a(bǔ)m,is替，were來(lái)把換掉動(dòng)詞are
2. do和be動(dòng)詞的用法區(qū)別
Be 動(dòng)詞就是(am，are,is)..句子中如果沒(méi)有實(shí)意動(dòng)詞(例如:write，buy)之類的動(dòng)詞，就直接在主語(yǔ)后面加Be動(dòng)詞。而如果是句子中有實(shí)意動(dòng)詞，那么如果你要改為一般疑問(wèn)句，就要借助DO(do也稱為助動(dòng)詞)，例如:I study.
改為一般疑問(wèn)句:Do you study ?
順口溜：be氏三朵花, am, is還有are,
我(I)戀am, 你(you)戀are,
is跟了他(he)她(she)它(it),
單娶is, 復(fù)娶are。
詳細(xì)講解：
英語(yǔ)的be 動(dòng)詞是個(gè)用法比較復(fù)雜的動(dòng)詞。復(fù)雜的原因有兩點(diǎn)：
1、 除了原形的 be 之外，對(duì)于不同人稱代詞以及單數(shù)名詞和復(fù)數(shù)名詞，be 會(huì)有各種變化形式和縮寫(xiě)形式。概括一下有七種形式：be, am, is, are, was, were, been, being。它們與人稱代詞和名詞單、復(fù)數(shù)的搭配關(guān)系是：
現(xiàn)在時(shí) I am, you are, he/she/it/ is, we/you/they are；名詞單數(shù)、不可數(shù)名詞用is，復(fù)數(shù)用are。
縮略式 I'm, you're, he's, we're, you're, they're
否定縮略式 I'm not, isn't, aren't
過(guò)去時(shí) I was, you were, he/she/it/ was, we/you/they were；名詞單數(shù)、不可數(shù)名詞用was，復(fù)數(shù)用were。
否定縮略式 wasn't, weren't
過(guò)去分詞 been
現(xiàn)在分詞 being
2、在句子中，be有兩種主要作用：一是作為系動(dòng)詞(The Linking Verb)，本身可以作用謂語(yǔ)動(dòng)詞；二是做為助動(dòng)詞(The Auxiliary Verb)，與謂語(yǔ)動(dòng)詞一起構(gòu)成各種時(shí)態(tài)和被動(dòng)語(yǔ)態(tài)等。
下面做個(gè)簡(jiǎn)要的講解。
一、be 動(dòng)詞做系動(dòng)詞
1、系動(dòng)詞+表語(yǔ)”的結(jié)構(gòu)
當(dāng)be 動(dòng)詞做系動(dòng)詞使用時(shí)，主要構(gòu)成“系動(dòng)詞+表語(yǔ)”的結(jié)構(gòu)，在句子中做謂語(yǔ)。表語(yǔ)可以是名詞、形容詞、副詞、介詞短語(yǔ)等。例如：
The man is a science teacher.

2、be 動(dòng)詞的一般疑問(wèn)句，方法是把be 移到主語(yǔ)前面，也可說(shuō)成是移到句首。

Are Mary's new dresses colourful? Yes, they are. / No, they aren't.

3、be 動(dòng)詞用在特殊疑問(wèn)句
在特殊疑問(wèn)句里，be 動(dòng)詞仍然移到主語(yǔ)前面，但特殊疑問(wèn)句是以特殊疑問(wèn)詞開(kāi)頭的，所以be 動(dòng)詞只能說(shuō)是移到主語(yǔ)前面，或者說(shuō)是在特殊疑問(wèn)詞的后面。例如：
Whose bike is broken? Xiao Ming's bike is.
Who was singing in the room? Mr. Zhang was.
Where are you from? I am from Wuhu.
What class were you in? We were in Class 2.
How old is Tom? He is ten.

He was not often late for his class when he was a student.
I wasn't here yesterday.

5、be 動(dòng)詞的祈使句

Don't be silly!
Don't be a fool!
Do be obedient!

二、be 動(dòng)詞做助動(dòng)詞
助動(dòng)詞be 有兩個(gè)基本用法，一是與謂語(yǔ)動(dòng)詞一起構(gòu)成各種時(shí)態(tài)，二是構(gòu)成被動(dòng)語(yǔ)態(tài)。
1、“be + 現(xiàn)在分詞組”成各種進(jìn)行式時(shí)態(tài)。例如：
Tony's maid is washing his new car.
The children are playing in the field.
Samuel was eating when I came in.
We have been living here since 1959.
This time next day they will be sitting in the cinema.
三、注意事項(xiàng)
英語(yǔ)句子中，為了表達(dá)時(shí)態(tài)或被動(dòng)語(yǔ)態(tài)的需要，常常會(huì)出現(xiàn)幾個(gè)助動(dòng)詞連在一塊兒使用。也就是說(shuō)，助動(dòng)詞be會(huì)和其它助動(dòng)詞一起使用。這時(shí)候，整個(gè)句子的一般疑問(wèn)句和否定句，就不一定是對(duì)be 進(jìn)行變化了，而是以第一個(gè)助動(dòng)詞為主進(jìn)行變化。即哪個(gè)助動(dòng)詞在先，就以它為主進(jìn)行變化。例如：
[肯定句] All the wonderful birds can be found in our Bird Park. (助動(dòng)詞有兩個(gè)：can be )
[疑問(wèn)句] Can all the wonderful birds be found in our Bird Park? (移第一個(gè)can)
[否定句] All the wonderful birds can not be found in our Bird Park. (在第一個(gè)can 后加not)
[肯定句] I have been there before. (兩個(gè)助動(dòng)詞：have, been )
[疑問(wèn)句] Have you been there before?
[否定句] I have not been there before.
[肯定句] I shall be having my supper at six tomorrow evening. (兩個(gè)助動(dòng)詞：shall, be )
[疑問(wèn)句] Will you be having my supper at six tomorrow evening?
[否定句] I shall not be having my supper at six tomorrow evening.
四. 助動(dòng)詞be，無(wú)詞義，輔助主要?jiǎng)釉~一起在句中作謂語(yǔ)動(dòng)詞。用法如下：
1. be+doing：構(gòu)成進(jìn)行時(shí)態(tài)，有現(xiàn)在和過(guò)去兩種進(jìn)行時(shí)態(tài)。如：
The girls is reading and copying the new words now.
Young Tom was always asking questions and trying out new ideas.

Oh, cool! And there are many things to see. There is even a deer park in Sanya.
There are about 80 pyramids in Egypt.
