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 已经结束了。
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：
1. Mother has me go to the shop to buy some fruit. 妈妈让我去商店买些水果。 2. He had/ got his computer stolen the other day. 前天，他的电脑被偷了。

3. He will have/ get the computer repaired tomorrow. 他明天会去修电脑。 2) leave/ keep +sb./ sth. done sth.（使……处于/保持某种状态）

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（表被动）. I can’t go out with all these clothes to wash（表将来）. Step 4 Practice
