动名词

动词+ing，具有名词的性质和功能，叫做动名词。动名词可做主语、宾语和表语。

Swimming makes you healthy.
swimming做主语

My job is teaching children.
teaching 做表语

I love playing sports.
playing 就是宾语的一部分。

常用的动名词作宾语的动词还有：

• finish doing sth.
• enjoy doing sth.
• mind doing sth.
• stop doing sth.
• remember doing sth.
• like doing sth.
• love doing sth.
• hate doing sth.
• try doing sth.
• forget doing sth.

现在分词

通常用于描述人或事物本身的特性用现在分词（-ing），过去分词（-ed）通常表达人的感受。

That is a interesting book.
那是一本有趣的书。（这里的 interesting 做定于）

This film is boring.
乏味的电影。（boring 作表语）

如何区分是动名词还是现在分词？

She likes playing basketball.

在这个句子中，playing 作为宾语，属于名词性用法，所以是动名词。

She is playing basketball.

这里的 playing 作为谓语，是现在分词。

难点

现在分词相当于形容词，可以做表语；动名词相当于名词，也可以作表语。
