完成式: 表明动名词动作在谓语动作前发生, 使用having done He was praised for having made a great contribution to his country. His having been elected chairman of the club surprised us greatly. The picture reminded us of having been taken to the zoo. 动名词的语态

被动式:表明动名词的逻辑主语是该动作的承受者 He did it without being asked.

Participles

分词

分词(过分和现分)兼有v.和adj.的特征,可带宾(现分)或状语构成分词短语 When visiting Beijing, he went to the Great Wall. It is an interesting story.

现分与过分的区别

A. 语态不同。现分表示主动的意思,过分多由及物v.变来,常表被动的意义。 surprising (令人惊讶的--主动) surprised (感到吃惊的--被动)

More Examples an exciting story the exploiting classes (剥削阶级)

a moving film(感人的) a tiring journey

excited spectators

the exploited classes(被剥削阶级)

a moved audience(被感动的) a tired football player

有些过分由不及物动词变来,只表示一个动作已完成;无被动意义.

fallen leaves, the exploded bomb, a retired miner, escaped prisoners, the risen sun.

B. 时间关系不同。现分表示的动作正在进行,而过分表示的往往已完成。 the changing world----the changed world boiling water----boiled water

developing countries----developed countries

分词的语法功能:作表语 1) 作表语

The situation is discouraging. She felt discouraged at the words.

现分作表语有主动的含义,它表示主语的性质或特征; 过分作表语有被动的含义,它表示主语所处状态或具有的情感

作定语

2) 作定语

I'm reading a very attracting book. He likes to drink cold boiled water.

一般,分词作前置定语泛指一般情况 Eg. An excited child is not easy to control.

分词作后置定语时,是特指某一特定情况下的特点,具有特殊含义。 Eg. The child excited by the gift was brought under control.

There's a broken window in their classroom.

The window broken yesterday will have to be paid for.

She said she would never get married, because she didn't want to spend her life surrounded by screaming children. The child screaming there is his son. 作宾语的补足语

3)分词作宾语的补足语只用于下列结构:

(1) 当v.为表示感觉或心理状态时,这些v.包括

see, hear, feel, watch, notice, smell, find, think, observe, listen to, catch, leave, start, set Examples

a. I saw a girl standing by the goldfish pond. b. He felt his eyes dazzled by the bright light. c. I found him drinking my mineral water. d. Everyone thought the battle lost.

e. Have you ever heard a nightingale singing?

(2) 当v.为make, get, have, keep等表示―致使、使得‖含义时: a. I have my hair cut every ten days. b. He got his bad tooth pulled out.

c. She's going to have her clothes altered.

(3) 在have+宾+p.p.结构中,have 有三种不同含义。 a. We had the problem solved. (意为―致使‖有意的行为)

b. He had his arms broken in an accident. (意为―遭受‖,表示无意行为) c. I have no money left. (have有)

(4) 当v.为like, want, wish, order等表示希望要求命令等意义时 a. He wanted his eggs fried.

b. He won't like such questions discussed at the meeting. c. The boss ordered all the errors corrected.

与不定式作宾补的区别

注:有些动词如see, feel, notice, watch即可跟现分也可跟不定式作宾补,区别在于:现在分词着重说明动作正在发生,不定式说明动作的全过程。 I saw the boys climbing the wall. (在爬) I saw the boys climb the wall. (爬了)

作状语 4) 作状语:

(1) 作时间或原因状语,常位于句前

a. Arriving at the station, he found a crowd of people waiting there. b. Inspired by the excellent situation, the workers worked even harder.

(2) 表示让步或条件

a. Heating water, you can change it into steam.

b. Though beaten by another football team, the players of GuoAn did not lose confidence. 省略

在上述两种情况下,分词所做的状语可以相当于一个状语从句。此时可在分词前加一个引导词如when, if, though, unless, before, after等 ,这就构成了省略。 Arriving at the station, he found a crowd of people waiting there.

= When he arrived at the station, he…… = When arriving at the station, he…… More Examples

Inspired by the excellent situation, the workers worked even harder. = After/Because they were inspired by …… = After/Because inspired by ……

Heating water, you can change it into steam. = If you heat water, you can …… = If heating water, you can……

Though beaten by another football team, the players of GuoAn did not lose confidence. = Though they were beaten by ……

(3) 表方式、结果及伴随状况。(不能用相当的状从替代) a. Laughing and talking, the students went out from the cinema. b. He came running back to tell us the news. c. She stood there waiting for the bus.

d. The bandits fled into the mountains, pursued by the policemen. 匪徒向山里逃窜,警察在后面追捕着。 分词独立结构

分词独立结构:一般分词作状语时,它的逻辑主语应是句子的主语,但有时分词的逻辑主语是其它的名 / 代词,n. / pron. +分词的结构就是独立(主格)结构。 A new technique ____, the yields as a whole increased by 20%. (90.1 CET-4) Answer: having been worked out. 分词独立结构的功能

3)从句动作发生在主句动作之后,从句would do. Examples
