【知识点1】population的用法
知识点再现
What is the population of Beijing 北京的人口有多少？（P72）
（1）英语中询问人口的多少不能用how much 或how many，而要用 what。常用句型为“What’s the population of+地点 ”，还可以用“What about the population of+地点？”或“How large/big+be+the population of+地点、范围？”的句型来对人口数量的多少提问。
（2）population是个集合名词，意为“人口；人数”。
【拓展】
（1）population在句中作主语时，谓语动词多用单数形式，但是若出现分数、百分数修饰人口时，谓语动词用复数形式。
（2）表示某国、某城市有多少人口时，可用“某地+ has /have a population of...”或“It’s about+数量词+in+某地”结构。
（3）不能用many, few, much, little等词修饰population，而要用large, big或small修饰。
