The world\'s population is increasing faster and faster.全世界的人口增长得越来越快。
(2)当主语是表示“人口的百分之几、几分之几”时，谓语动词用复数形式。eg：
About seventy percent of the population in China are farmers.中国大约有百分之七十的人口是农民。
(3)有时population可用作可数名词，其前面可用不定冠词。eg：
New York is a big city with a population of over 10 million.纽约是一个有一千多万人口的大城市。
(4)表示人口的“多”或“少”，不用“much”或“little”，而要用“large”或“small”。eg：
Singapore has a small population.新加坡人口少。
(5)询问某国、某地有多少人口时，不用“How much…？”，而用“How large…？”；问具体人口时用“What\'s the population of …？”。eg：
How large is the population of your hometown?
你们家乡有多少人口？
