单元语法———动词-ing 形式作主语和宾语
要点一 动词-ing 形式通常有以下几种变化形式(以do 为例)

一般式doing being done
完成式having done having been done
一般式:表动作与谓语动词的动作同时或在其后发生,或表示一般情况。
完成式:表动作发生在谓语动词的动作之前。
主动语态:它的逻辑主语是动作的执行者。
被动语态:它的逻辑主语是动作的承受者。

(2)Would you mind     (open) the window?
(3) Seeing the picture,he couldn’t help     (laugh).
(4)       (praise) by the teacher made him inspired.
going
opening
laughing
Being praised
要点二 动词-ing 形式的复合结构
动词-ing 形式加上自己的逻辑主语,便构成了动词-ing 形式的复合结构。具体形式有:
(1) 形容词性物主代词(如his)
(2) 名词所有格(如Tom’s)
(3) 人称代词的宾语(如him)
(4) 名词普通格(如Tom)
◆误区警示
动词-ing 形式的复合结构作主语时,只能用形容词物主代词或名词所有格。


+doing
◆单句语法填空
(1) It is difficult to imagine his      (accept)the decision without any consideration.
(2)We greatly appreciate you     (give)us a timely hand when faced with trouble.

his/him/Tom’s/Tom coming to deliver a speech to us
要点三 动词-ing 形式作主语
(1)位置
动词-ing 形式作主语时:一种是-ing 形式位于句首;
另一种是it 作形式主语,而将动词-ing 形式后置。单个的动词-ing形式+ 单数谓语。
(2)常用动词 -ing 形式作主语的句型:
It is a waste of time doing... 做……是浪费时间的。
It is no good/use doing... 做……是没用的。
It is worthwhile doing... 做……是值得的。
It is no fun doing... 做……没有乐趣。
( 3)动词 -ing 形式和 to do 作主语时的区别
动词-ing 形式作主语表示比较抽象的一般行为, to do 作主语往往表示具体的或一次性的动作。

在下面的短语中,常用动词-ing 形式作介词的宾语:be good at,dream of,care about,
be concerned about,be interested in,feel like,insist on,think of,aim at,set about等。
◆误区警示  
下列短语后接动词-ing 形式,因为to 为介词,不是不定式符号。

devote oneself to 献身于 lead to 导致
be used to 习惯于 look forward to 期待
get down to 开始做 stick to 坚持
object to 反对 pay attention to 注意

try to do... 努力/ 试图做…… try doing... 试着做……
mean to do... 打算做…… mean doing... 意味着做……
stop to do... 停下来去做(另一件事) stop doing... 停止做……

(4)用 it 作形式宾语,真正的宾语是动词-ing 形式

(5)介词 in 常可省略的几类句型
① 主语+have trouble/difficulty/a problem/a good/hard time(+ in)+doing...
② 主语+ spend time (+ in)+ doing...
③ 主语+ be busy (+ in)+ doing...
(6)主动形式表被动意义
