2019考研英语语法全面举例讲解：动名词做主语和表语

动名词可以起名词的作用，在句子中作主语，宾语，表语，定语。动名词仍保留动词的一般特征，可以有自己的宾语和状语，构成动名词短语。 动名词的否定形式是在前面加上not, never等否定词。

做主语和表语。

动名词短语用and连起来做主语时，谓语用复数形式。

例如：

Fishing in this lake is forbidden. 这个湖里禁止钓鱼。

Going abroad for a visit and settling down abroad are two different things. 出国访问和在国外定居是两件不同的事情。

It seems that reading English is easier than speaking it.似乎读英语比说英语容易。

My favorite hobby is fishing/collecting stamps .  我最喜欢的爱好是钓鱼/集邮。

在It’s no use; It’s (no) good; It’s useless ; It’s (not) wise; It’s (not) worthwhile; It’s of great (no, little) importance 等习惯表达中，It为形式主语，而将做主语的动名词短语放在后面。例如：

It’s no use /good ringing her up now. 现在给她打电话没用了。

Is it worthwhile bargaining two hours for two cents?    为两分钱讲价两小时值得吗?

It’s wise trying again. 再试一次是明智的。

It is of great importance fighting against pollution.  制止污染有重要意义。

It is no use operating on the sick man. He should have been sent here early. 给这个病人做手术已经没用了。本应该早些把他送来。

It is no good smoking; you’d better give it up. 吸烟没好处，你最好戒掉。
