2. v-ing(现在分词)的含义:
v-ing(现在分词),在句中作状语,通常表示主语正在进行的另一动作,用来对句子谓语动词起修饰和陪衬的作用。
1). 时间
2). 条件
3). 原因
4). 让步
5). 结果
6). 方式或伴随状语情况等
现在分词在句中作状语可以表示
相当于对应的状语从句

she
she
1).现在分词(短语)作时间状语时,相当于when引导的时间状语从句,状语常放在句子的前半部分。
(v1)
(v2)
Coming
① v1与v2几乎同时发生
②主动关系
③同时she与主句主语相同
=Coming into the room, she saw everybody already at their work.(coming into the room作时间状语)
[① v1与v2同时发生, ②she与came存在着主动关系, ③同时she与主句主语相同,用doing形式,因此,此处用coming引导]
2).现在分词(短语)作条件状语时,相当于if, unless等引导的条件状语从句。
If you look out of the window, you can have a full
view of the beach. ?
=Looking out of the window, you can have a full view of the beach.
(Looking out of the window作条件状语)
?
(v1)
(v2)
① v1与v2几乎同时发生(可弱化)
you
you
②主动关系
③同时you与主句主语相同
Looking
[① v1与v2几乎同时发生(可弱化), ②you与look存在着主动关系, ③同时you与主句主语相同,用doing形式,因此,此处用looking引导]
[① v1与v2几乎同时发生(可弱化), ②I与knowing存在着主动关系, ③同时I与主句主语相同,用doing形式,因此,此处用knowing引导]
3).现在分词(短语)作原因状语时,相当于as, since, because引导的原因状语从句,状语多放在句子的前半部分。
As I don’t know his address, I can’t send this book to him.
(v1)

4).现在分词(短语)作让步状语时,相当于though, even if 等引导的让步状语从句。

③同时the old man与主句主语相同
[① v1与v2几乎同时发生(可弱化), ②the old man与was存在着(表状态的)主动关系, ③同时the o与主句主语相同,用doing形式,因此,此处用being引导]
5).现在分词(短语)作结果状语时,相当于so that引导的结果状语从句,结果状语通常放在句子后。现在分词前可以有副词thus 或only修饰,并用逗号和前面的句子成分隔开,常意为“于是,所以,因而”。分词的逻辑主语既可以是句子的主语,也可以是前面的整个句子,逻辑主语为整个句子时,其作用相当于一个非限制性定语从句。

My car was caught in a traffic jam, thus causing the delay. (causing the delay作结果状语)
