在句子中充當(dāng)除謂語以外的句子成分的動詞形式叫做非謂語動詞。非謂語動詞分為三種形式:不定
式，動名詞，和分詞(分詞包括現(xiàn)在分詞和過去分詞)。
1）不定式
時態(tài)\語態(tài) 主動 被動
一般式 to do to be done
完成式 to have done to have been done
2）動名詞

一般式 doing being done
完成式 having done having been done
3）分詞
時態(tài)\語態(tài) 主動 被動
一般式 doing being done
完成式 having done having been done
否定形式： not +不定式， not + 動名詞， not + 現(xiàn)在分詞
動名詞
1 動名詞作主語、賓語和表語
1）作主語

2）作賓語
a. 動詞后加動名詞doing作賓語 V. + doing sth

(2) The squirrel was lucky that it just missed being caught.
b. 詞組后接doing

3）作表語

2 worth 的用法
worth，worthy，worth-while都為adj. 意為"值得"。
1. worth： be worth + n. 當(dāng)名詞為金錢時，表示"…… 值得……"
be worth doing sth. "……某事值得被做"
The question is not worth discussing again and again.
2. worthy：be worthy of +n. 當(dāng)名詞為抽象名詞時表示"……值得……"

典型例題
It is not ____ to discuss the question again and again.
A.worth B.worthy C.worth-while D.worth while
答案C. 由worth的用法可知，此句只適合詞組be worth-while to do sth.。因此選C。
動詞不定式
1 不定式作賓語
1) 動詞+ 不定式
afford aim appear agree arrange ask be decide bother care choose come dare demand desire determine expect elect endeavor hope fail happen help hesitate learn long mean manage offer ought plan prepare pretend promise refuse seem tend wait wish undertake
舉例：

例句：
a. Father will not allow us to play on the street.
父親不讓我們在街上玩耍。
b. We believe him to be guilty.
我們相信他是有罪的。
Find 的特殊用法：
Find 后可用分詞做賓補(bǔ)，或先加形式賓語，再加形容詞，最后加帶to 的動詞不定式。find后也可帶一個從句。此類動詞還有g(shù)et，have。
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例題:
The next morning she found the man ___ in bed，dead.
A. lying B. lie C. lay D. laying
答案：A.find的賓語后面，用分詞或分詞短語，起賓語補(bǔ)足語作用。現(xiàn)在分詞表達(dá)主動，也表達(dá)正在進(jìn)行，過去分詞表達(dá)被動。

典型例題

A. to invent B. inventing C. to have invented D. having invented
答案：A. 由consider to do sth. 排除B、D。. 此句只說明發(fā)明這一個事實，不定式后用原形即可。而C為現(xiàn)在完成時，發(fā)明為點動詞一般不用完成時，且此處也不強(qiáng)調(diào)對現(xiàn)在的影響，因此不選C。
3) to be +形容詞
Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean…

3) 當(dāng)不定式作主語的句子中又有一個不定式作表語時，不能用It is… to…的句型
(對)To see is to believe. 百聞不如一見。
(錯)It is to believe to see.
4 It's for sb.和 It's of sb.
1）for sb. 常用于表示事物的特征特點，表示客觀形式的形容詞，如easy, hard, difficult, interesting, impossible等：
It's very hard for him to study two languages. 對他來說學(xué)兩門外語是很難的。

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：
用介詞后面的代詞作主語，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(yīng)用of)。
He is hard. (人是困難的，不通，因此應(yīng)用for。)
5 不定式作表語
不定式可放在be動詞后面，形成表語。例如：
My work is to clean the room every day.

6 不定式作定語
不定式做定語通常要放在被修飾的詞后。例如：

3) 表原因
I'm glad to see you.
典型例題
The chair looks rather hard, but in fact it is very comfortable to ___.
A. sit B. sit on C. be seat D. be sat on
答案：B. 如果不定式為不及物動詞，其后應(yīng)有必要的介詞。當(dāng)動詞與介詞連用時，常位于"形容詞+動詞不定式"結(jié)構(gòu)的末尾。
8 用作介詞的to
to 有兩種用法： 一為不定式+動詞原形； 一為介詞+名詞/動名詞, to 在下面的用法中是第二種，即to+ 名詞/動名詞：

8） 由and, or和than連接的兩個不定式，第二個to 可以省去：
9） 通常在discover, imagine, suppose, think, understand等詞后，可以省去to be：
He is supposed (to be) nice. 他應(yīng)該是個好人。
舉例：
He wants to move to France and marry the girl.
He wants to do nothing but go out.

A. not to B. not to do C. not do it

5) The patient was warned ___ oily food after the operation.
A. to eat no B. eating not C. not to eat

答案：C。由題意可知，她到了山頂，停下來在一個路邊的大石頭上休息。因此，應(yīng)選擇"stop to do sth. 停下來去做另一件事"。而不僅僅是爬山動作的終止，所以stop doing sth.不正確。

decided that Mr.Chen was more suited
to the job.

二、-ING分詞與-ED分詞的區(qū)別
雖然在語法功能上，-ED分詞在句子中所能承擔(dān)的成分基本與-ING分詞相同，但在意義上兩者有差別：-ING分詞表示主動的意義，而-ED分詞則表示被動的意義；-ING分詞表示一般性的或正在進(jìn)行的動作，而-ED分詞則表示已經(jīng)完成和被動的動作。在表現(xiàn)形式上，-ING分詞有"一般式"和"完成式"與"主動式"和"被動式"之分；而-ED分詞只有一種形式。下邊我們分析-ING分詞與-ED分詞在語法功用上的區(qū)別。
1. 作表語時，-ING分詞表示主語所具有的特征而-ED分詞表示主語所處的狀態(tài)
The book is quite interesting. I am insteredted in the book very much.
The play is more exciting than any I have
ever seen. That piece of land lay deserted.
2. 作狀語時-ING分詞表示主語正在進(jìn)行的另一動作而-ED分詞則表示主語發(fā)生動作的背景或情況 11) In his movies，W. C. Fields was always at war with the world， .

［B］ Sonia Sanchez has also written a number of books and plays
［C］ a number of Sonia Sanchez's books and plays have been written
［D］ there have been a number of books and plays written by Sonia Sanchez
3. ①作定語時，-ING分詞表示正在進(jìn)行的動作，而-ED分詞表示動作發(fā)生在謂語動詞之前；②-ING分詞表示它所修飾的詞經(jīng)常或當(dāng)時的狀態(tài)，而-ED分詞則沒有時間性；③-ING分詞表示主動，而-ED分詞表示被動
15) The boiled ［A］ point of any liquid ［B］ is determined ［C］ by the pressure ［D］ of the surrounding gases.
16) High-grade ［A］ written ［B］ paper is frequently ［C］ obtained ［D］ from cotton rags.
17) Scientists ［A］ still cannot find ［B］ any convinced ［C］ link between intelligence ［D］ and the quantity or quality of brain cells.
4. 但少數(shù)幾個動詞的-ED分詞，有兩種形式而且在意義上有差別，如：bear的-ED分詞有born和borne之分，前者只用于"出生"的意義，而后者用于"負(fù)擔(dān)"，"負(fù)荷"，"承擔(dān)"和"傳送"之意
I was born in 1966.
His borne responsibility to the whole workers of the factory is really great.
再如：hang的-ED分詞也有兩種，一是hung,另一形式是hanged, 前者表示"懸掛"，后者表示"吊死，絞死"。strike的-ED分詞也有兩種：struck和striken, 前者有"打擊""沖擊""感動"等義，而striken只用作形容詞，表示"受折磨"之意。
來自及物動詞的-ED分詞所表示的是被動意義；來自不及物動詞的-ED分詞則可表示主動和完成的意義：fallen leaves (落葉)，a full-blown rose (盛開的玫瑰), escaped prinsoners(逃犯), the exploded bomb, her deceased husband, the retired workers, the vanished jewels, the newly arrived visitors, the returned students, the risen sun.
三、例題解析
1) A為正確答案。(一般性的動作。)
2) A為正確答案。(連續(xù)的動作。)
3) D錯。 改為harvesting(抽象的動作)。
4) A為正確答案。(已完成的動作。)
5) C錯。 改為to be interviewed(將要發(fā)生的動作)。
6) C錯。改為to kill(不定或未來動作)。
7) D為正確答案。(過去經(jīng)常或總是干……)
8) A為正確答案。(習(xí)慣于……used是形容詞)
9) A錯。改為jog。(表示過去經(jīng)常或總是干……)
10) A為正確答案。
11) A為正確答案。
12) B為正確答案。本句是由-ED分詞"noted"引導(dǎo)的-ED結(jié)構(gòu)，在句中說明主句謂語的背景。
13) B為正確答案。
14) B為正確答案。-ED分詞"considered"的邏輯主語應(yīng)為人，除B外的其他選項都無法和空白前-ED結(jié)構(gòu)在邏輯主語上一致。
15) A錯。改為boiling。-ED分詞含有完成和被動的意思，-ING分詞則表示主動、進(jìn)行，也可用作前置定語表示性狀、用途。如："boiling water(water which is boiling.)"意思是"開水"，意即"正在開著的水"，而"boiled water(water which has been boiled.)"雖也可譯為"開水"，但表示"已開過了的水(現(xiàn)在可能涼了)。"本句A處應(yīng)改為boiling，"boiling point"意思是"沸點"。
16) B錯。改用"writing"，"writing paper"意為"寫字的紙，信紙"，-ING分詞"writing"表用途。與此類似的還有"swimming pool"(游泳池) ，"sleeping car"(臥鋪) 。"written"含有完成和被動意味，不合上下文。
17) C錯。改為"convincing"。"令人信服的聯(lián)系"應(yīng)為"convincing link"，"convincing"含有主動的意味，即"聯(lián)系"(link)本身具有這種性質(zhì)，而"convinced"則含有完成或被動的含義， 修飾有生命的名詞 。試比較：a surprising man (使人驚訝的人) ，a surprised man (被驚嚇了的人)
