5. 基数词、序数词的复数使用情况
基数词用于表示事物的数量,在表示基数词时,要特别注意hundred, thousand,million的用法:若其前面使用的基数词,则不论其后面是否有of,都必须用单数形式(此时若带of则通常表示特定范围中的一部分);若泛指数百、数千、数百万,则用hundreds of, thousands of, millions of等这样的结构。
e.g. 操场上有300名学生。
There are three hundred students in the playground.
这些人中的两百个是来自这个学校的学生。
Two hundred of these men are students from this school.
因为我有成千上万个理由爱你。
