动词的-ing形式作状语
一、 动词的-ing形式作状语时,通常都表示主语正在进行的
另一动作,用来对谓语动词表示的动作加以修饰或作为陪衬。它可表示时间、原因、结果、条件、让步、方式或伴随动作,相当于相对应的状语从句。
二、 注:从句的主语和主句的主语必须一致。即-ing分词作
状语时,它的逻辑主语就是整个句子的主语,并表示主动的关系。 三、 1.
表示时间,代替时间状语从句
Walking in the street, I met a friend of mine.
=When I walked in the street, I met a friend of mine.
2. 表示原因,相当于一个原因状语从句,多置于句首或
句末,也可置于句中
She rang him up, hoping to get his support. = As she hoped to get his support, she rang him up. Being ill, he didn’t go to school =As he was ill, he didn’t go to school
3.
表示条件,多置于句首
Working hard, you will succeed. =If you word hard, you will succeed.
4.
表示让步,多置于句首
Being poor, the old man was happy.
=Though he was poor, the old man was happy. 5.
表示结果,常置于句末
表示方式或伴随,多置于句末,也可置于句首
1) He sat at the table, reading a magazine.
The boy fell off his bike, breaking his right arm. = The boy fell off his bike, so he broke his right arm. 6.
2) Laughing and talking, they went into the room. 四、为强调与谓语动词的动作同时发生,在-ing形式短语前可用连词when, while等;为强调在谓语动词的动作之前或之后发生,在-ing形式短语前可用连词before或after e.g. 1) Be careful when crossing the road. 2) Don’t laugh while eating.
3) Before going abroad, he lived here. 4) After watching TV, he went to bed.
五、在-ing形式短语前可用介词on,表示“一……就……” e.g. On arriving in Beijing, he went to see his uncle.(= As soon as he arrived in Beijing, he went to see his uncle.)
