【知识点1】population的用法
知识点再现
What is the population of New York 纽约的人口有多少?(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。
