1、2022年高三英語(yǔ)語(yǔ)法訓(xùn)練 非謂語(yǔ)動(dòng)詞專(zhuān)題
不定式的用法：
1．作主語(yǔ)；不定式短語(yǔ)作主語(yǔ)時(shí)，往往放在謂語(yǔ)之后，用it作形式主語(yǔ)。
To see is to believe.
It’s right to give up smoking.
2．作表語(yǔ)；My job is to help the patient.
果這些句子變成被動(dòng)結(jié)構(gòu)時(shí)，就必須帶to符號(hào)。如：
I often hear him sing the song.
He is often heard to sing the song.
注意： 動(dòng)詞不定式在介詞but后面時(shí)， 如果介詞之前有行為動(dòng)詞
2、do的各種形式，那么，這些介詞后的不定式不帶to，否則要帶to。另外，在can’t choose but和can’t help but等后面的不定式也省略to。如；
We could do nothing but wait.
We have no choice but to wait.
5．作定語(yǔ)；1）. 作定語(yǔ)的不定式如果是不及物動(dòng)詞，或者不定式所修飾的名詞或代詞是不定式動(dòng)作的地點(diǎn)，工具等，不定式后面須有相應(yīng)的介詞。如：
There is nothing to worry about.
The Browns have a fortable house to live in.
Pl
3、ease give me a knife to cut with.
但是，不定式所修飾的名詞如果是time,place或way時(shí)，不定式后面的介詞習(xí)慣上省去。如：
He had no and no place to live.
We found a way to solve this problem.
2）. 當(dāng)作定語(yǔ)的不定式所修飾的名詞或代詞是不定式動(dòng)作的承受者時(shí)，不定式既可以用主動(dòng)語(yǔ)態(tài)，也可用被動(dòng)語(yǔ)態(tài)，但其含義有所不同。試比較：
Have you anything to send? / Have you anything to be sent?
3）. 不定式作定語(yǔ)
4、的幾種情況：
a.作后置定語(yǔ)可表將來(lái)：The meeting to be held tomorrow is very important.
b.用來(lái)修飾被序數(shù)詞，最高級(jí)等限定的中心詞：
He was the best man to do the job.
She was the first woman to win the gold medal in the Olympic Games.
c.用來(lái)修飾的詞是抽象名詞時(shí)，常見(jiàn)的有：ability, chance, idea, fact, answer, reply, attempt等。如：
Do you have the abili
5、ty to read and write English?
I have no chance to go sightseing.
6．作狀語(yǔ)；表目的，原因，結(jié)果或條件。如：
I came here to see you.(目的)
He hurried to the school to find nobody there.(結(jié)果)
To look at him, you would like him.(條件)
在某些形容詞作表語(yǔ)，表示喜，怒，哀，樂(lè)后跟不定式表原因。如：
We were very excited to hear the news.
在帶有enough或too的句
6、子里，也常用不定式作狀語(yǔ)，表示程度。
He is old enough to go to school.
She is too tired to do the job.
注意：目的狀語(yǔ)還可以用in order to或so as to來(lái)表示但so as to不能置于句首。
7．作獨(dú)立成分；如：
To tell you the truth, I have got no money about me.
To be honest, I know nothing about it.
不定式與疑問(wèn)詞who, which, when, where, how, what等連用，在句中起名詞作用，
7、可充當(dāng)主語(yǔ)，表語(yǔ)，賓語(yǔ)等。如：
He didn’t know what to say.(賓語(yǔ))
When and where to hold the meeting is not known yet.(主語(yǔ))
My question was how to get so many books.(表語(yǔ))
注意句型：Why not do sth.? Why do sth.?
l 不定式的主動(dòng)(to do )和被動(dòng)(to be done)
判斷不定式是主動(dòng)還是被動(dòng)，關(guān)鍵看不定式中的動(dòng)詞與主句的主語(yǔ)之間的關(guān)系，主動(dòng)即用“to do”，被動(dòng)即用“to be done”; 如果與主句主語(yǔ)之間沒(méi)
8、有關(guān)系，則看其與邏輯主語(yǔ)之間的關(guān)系，如果是被動(dòng)，則用“to be done”.試比較：
1) I have some clothes to wash, so I can’t go out now.(自己洗衣服)
2) Are you free now? I have some clothes to be washed.（叫別人洗衣服）
3) There are five pairs (for you) to choose from. (暗含主語(yǔ)you)
l 不定式的時(shí)態(tài)
to do/to be doing/ to have done
He pretended to be read
9、ing a book when she went in. (動(dòng)作正在進(jìn)行)
I’m sorry to have kept you waiting.(不定式動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞之前)
l 不定式符號(hào)to的保留問(wèn)題
有時(shí)為了避免重復(fù)，可以用來(lái)代替前面的不定式，這種情況常出現(xiàn)在下列動(dòng)詞后：expect, prefer, care, mean, forget, want, wish, hope, try以及be glad/happy;would like/love等后。
I have’t been to Hong Kong, but I wish to.
---- Are you on ho
10、liday?
---- No, but I’d like to be.
---- I didn’t tell him the news.
---- Oh, you ought to have.
動(dòng)詞-ing形式的用法(過(guò)去分詞):
1. 動(dòng)詞-ing形式作主語(yǔ)
Seeing is believeing.
Tom’s ing is what we have expected.
-ing或不定式都可以在句中作主語(yǔ)，但在下列句型中常用-ing作主語(yǔ)
It’s no use/good+doing sth./ It’s of little use/good+doing sth.
It
11、 is no use crying over spilt milk.
It is of little good staying up too late every day.
2．動(dòng)詞-ing形式作表語(yǔ)

3．動(dòng)詞-ing形式作賓語(yǔ)
以下動(dòng)詞或動(dòng)詞詞組后面只接動(dòng)名詞作賓語(yǔ)：admit, appreciate, avoid, consider(考慮), delay, enjoy, imagine, suggest, finish, mind, practise, re
12、sist, give up, feel like, keep on, insist on, look forward to, stick to, get down to等。
注意：1). 有些動(dòng)詞或動(dòng)詞詞組既可以跟動(dòng)名詞作賓語(yǔ)，也可以跟不定式作賓語(yǔ)，但意義上有區(qū)別，要特別注意。如：
forget to do/doing; remember; regret; try; mean; stop; go on; can’t help等。
2). 在動(dòng)詞等動(dòng)詞后直接跟動(dòng)詞形式作賓語(yǔ)，如果后面有名詞或代詞作賓語(yǔ)，其后用動(dòng)詞不定式作賓語(yǔ)補(bǔ)足語(yǔ)。如：
allow/advise/forbid/permi
13、t doing sth./ sb to do sth.
3). need, want, require其后必須用動(dòng)名詞的主動(dòng)形式或不定式的被動(dòng)形式作賓語(yǔ)，表示事情需要做。如：
Sth. need/requie/want doing=to be done
Sth. be worth doing
Sth. be worthy of being done=be worthy to be done
4．動(dòng)詞-ing形式作定語(yǔ)（過(guò)去分詞作定語(yǔ)）
前置定語(yǔ)：He asked an embarrassing queation.
后置定語(yǔ)：A little child learning to
14、walk often falls.
= A little child who learns to walk often falls.
注意：動(dòng)詞-ing和過(guò)去分詞的區(qū)別---現(xiàn)在分詞表示主動(dòng)含義或動(dòng)作正在進(jìn)行，過(guò)去分詞表示被動(dòng)含義或動(dòng)作已經(jīng)完成。如：
falling leaves/fallen leaves
boiling water/boiled water
a puzzling look/a puzzled look
Those inviting me to attend the meeting are my friends.
=Those who invite me to
15、attend the meeting are my friends.
Those invited to the meeting are all the top leaders from different countries.
=Those who are invited to the meeting are all the top leaders from different countries.
5．動(dòng)詞-ing形式作狀語(yǔ)（過(guò)去分詞作狀語(yǔ)）
分詞作狀語(yǔ)時(shí)，分詞的邏輯主語(yǔ)必須與句子的主語(yǔ)保持一致。
分詞或分詞短語(yǔ)作狀語(yǔ)時(shí)，可以表時(shí)間，原因，結(jié)果，條件，讓步，行為方式，伴隨狀況等。
16、表示時(shí)間關(guān)系的分詞短語(yǔ)有時(shí)可由連詞while或when引出。如：
Given more attention, the trees could have grown better.
Followed by some officials, the leader inspected his army.

一般式doing/done
完成式having done/ having been done
進(jìn)行式being done
否定式是not+分詞短語(yǔ)
l 獨(dú)立成分作狀語(yǔ)
有些分詞短語(yǔ)，其形式的選擇不受上下文的影響，稱(chēng)作獨(dú)立成分。常見(jiàn)的有：
Generally speaking,
Frankly speaking,
Judging from/by,
Considering,
Given,
