Language points

1.population的用法.

(1)population直接作主语时意为“人口数”,这时谓语动词要用单数形式。但是如果部分人口(分数、百分数)作主语,谓语用复数。

(2)表示“某地有多少人口”有两种表达方式: a.The

population of +某地+be+数词(该句型中population前用冠词the); b.某地+has a population of +数词+(people)(该句型中population前用冠词a)。

(3)“某地有多少人口”要用“What is the population of ...?”或“Howlarge is the population of...?”提问。

(4)表示人口“多”要用huge或large修饰,表示人口“少”要用small修饰。
