地点名词？”是一个提问人口数量的句型，表示“某地的人口是多少”；也可以用“How large / How big + be + the population of + 地点名词？”或“How many people are there + 地点状语？” 提问。

（1） population
是集体名词，前面不能用数词，作主语时，表示整体概念，谓语动词用单数形式，
例如：The population of the world is growing too fast , 世界人口增长得太快了。

来修饰。
例如：I think the population of India is smaller than that of China .
(3)提问人口数量时用what ,不用how many 和 how much 。
（4）如果population 前有百分数或分数修饰时，表示侧重于全体居民，是复数概念，谓语动词要用复数。
例如：20 percent of the population in this city are works .
