Step 3 More about v-ing as the object complement

1.在感官动词后作宾语补足语

在see, hear, feel, watch, notice等感官动词后，表示一个正在进行的主动的动作，强调一个过程或一种状态。

In the crowded cafe, I heard a friendly voice saying, “You can share my table.”

He saw a girl wandering on the street this time yesterday.

注意：see/hear/watch/feel/notice+sb./sth.+doing sth.强调动作正在进行

see/hear/watch/feel/notice+sb./sth.+do sth.强调动作发生的全过程/全过程已经结束

Today on my way home, I saw a man running along the street hurriedly.

I saw him enter the room and take something away.

2.在使役动词宾补结构中的使用使役动词接现在分词作宾语补足语，表示“让……一直做某事”。

It’s cold. We should have the fire burning all the time.

I won’t have you running about in the room.

注意：1）have/get+sb./sth.+done包括两层意思：①让别人去做某事。②（主语）遭受到（意外的损失或不幸）。

have +宾语+do sth.. 意思是“让某人去干某事”。

翻译：

①Mother has me go to the shop to buy some fruit.

______________________________

②He had/got his computer stolen the other day.

______________________________

③He will have/get the computer repaired tomorrow.

______________________________

2）leave/keep +sb./sth. done sth. （使……处于/保持某种状态）

Many teachers keep parents _________ (inform) of children’s performance in the kindergarten by sharing videos on WeChat.

3.现在分词在with复合结构中的使用

在with复合结构中，现在分词充当宾语补足语，表动作“正在进行”。

Does Kilimanjaro deserve its reputation as a crowded mountain with lines of tourists ruining the atmosphere of peace?

注意：在with的复合结构中，也可以使用不定式和过去分词作宾语补足语。

All the afternoon he worked with the door locked.（表_______）

4. Mother has the little girl ________ (play) the piano this afternoon.

5. I noticed a thief ___________ (steal) money from the old woman’s pocket yesterday.

6. Can you hear her ________ (sing) the song in the next room?

Step 5 More about v-ing as the adverbial

-ing形式作时间、原因、条件、让步状语时多位于句首；作结果、伴随情况状语时常位于句末。

1.表示时间。

Hearing these stories, I’m skeptical about the place.

= When ______________________________...

2.表示原因。

Not knowing his address, I can’t send this book to him.

= ______________________________...

3.表示结果。

His father died, leaving him a lot of money.

= ______________________________, left him a lot of money.

4.表示条件。

Going straight down the road, you will find the department store.

= ______________________________...

5.表示让步。

Being tired, they went on working.

= ______________________________...

6.表示行为方式、伴随情况或补充说明。

He lay on the grass, staring at the sky for a long time.

=…, ______________________________.

注意：非谓语动词作状语时，如所提供的动词不能和句子中的主语保持一致，动词-ing形式必须有自己的逻辑主语，通常由名词或代词来担任，这就是独立主格结构。

The last bus having gone, we had to walk home.

（having gone的逻辑主语是the last bus，而不是we）

Weather permitting, the football match will be played on Friday.

（permitting的逻辑主语是weather，而不是the football match）
