5.3 动名词的作用（三）：作表语
动名词用作表语，主要就是直接放在be动词后面，以补充说明句子主语的具体内容。请看例句：
1 His hobby is collecting stamps.
妙语点睛 这里的collecting stamps是用来说明hobby的内容，所以collecting stamps是动名词短语。
2 Reading is permitting a man to talk a long time, and refusing you the right to answer.
妙语点睛 这里的reading和refusing都是动名词，直接放在is后面作表语。
再比如下面这个对话涉及东西方文化的差异：
3 Nick: Another odd thing I see would be girls holding hands. If two girls their age did that in Britain we would think they were gay!
Lucy: It's just because girls get very close to each other and treat them as sisters.
Nick: I think that's very touching but I’m glad the boys don't do that!
妙语点睛 该句中的girls holding hands是一个动名词的复合结构，放在be后面作表语。
露西：这不过是因为女孩子们的感情很好，把彼此当作姐妹罢了。
