时态

一般式

完成式

主动态

doing having done 被动态

being done having been done 1.-ing分词的一般式和完成式：

Being a student, he was interested in books. Having finished his work, he went home.

-ing分词的一般式的动作表示和主句的动作是同时进行或者在主句的的动作之后发生；完成式的动作是先于主句的动作发生。

2. -ing分词的被动式

-ing分词的被动式表示与主句的主语（分词的逻辑主语）的关系是被动关系。根据-ing分词动作发生的时间，被动式有一般被动式(being done)和完成被动式(having been done)。如：

（Having been criticized）

by the teacher, he gave up smoking.

3．-ing分词的否定式

动词--- ing形式（短语）的否定形式常在其前面加not /never等

Not knowing his address, I could do nothing but stay at home and wait. Not having received his father’s letter, he decided to make a call to him.

Step3：现在分词作状语学与练

现在分词的功能：分词作状语可以表示：时间，原因，

条件，让步，方式，伴随，结果等

把划线部分改写成分词短语并说明其功能 1.-ing分词短语作时间状语

When they saw their teacher, the students stood up.

2.现在分词短语

作原因状语

Because he was ill, he couldn’t go to school.

3.现在分词短语

作条件状语

If you work harder at English, you will make greater progress. 4．现在分词短语

作让步状语

Although they felt very tired，they kept running. 5.现在分词短语

作伴随或方式状语

The children came into the classroom, and they laughed and talked.(并列句) Step4：使用- ing形式需注意的4个问题

1、分词 (短语) 作状语时, 前后两个动作的主语是同一个人。

2、分词短语做状语时，前面可以加上连词或介词，但是分词短语和句子之间不能用并列连词(如but，and)，分词和主句之间可用逗号。

3、用V+ing一般式

还是Having+done完成式，要看前后两个动作有没明显的先后顺序，在可能引起误解的场合应该用完成式现在分词表示先发生的动作。

4、分词的否定形式是在分词短语前面加上 not, never等否定词构成。
