动词加ing有什么问题（动词什么时候加ing）

​英语中动词加ing是最常见的动词词形变化，可以做谓语，也可以做非谓语，有两种称呼，一是现在分词，二是动名词。

我们先来看作谓语的情况.

这时候的动词加ing前面必须加上be动词,形成be 动词ing(现在分词)作句子谓语，构成进行时态句子。

例如:

He is reading a book now.他正在看书.

He was watching TV when his mother came in.他妈妈进来时，他正在看电视。

They've been waiting for you for three hours.他们等你三个小时了.

​现在我们来看动词加ing做非谓语的情况。

I'm looking forward to seeing you again.我期盼着再次见到你.

The boy is so excited about hearing from his mother.男孩为收到他妈妈的来信很兴奋。

2.部分动词用动词做宾语。做宾语的动词要加ing(动名词)！

The old man Enjoys living in the country.这老人喜欢住在农村.

3.一些固定句式后面要加动词ing(现在分词)。

​4、动词修饰名词做后置定语时，要加ing(现在分成)！ There is a boy Crying over there.
