根据牛津词典,population意为"人口。人口数量",也可以指"某领域的生物,族群"。它既是可数名词,也是不可数名词,没有严格区分。具体讨论:1. population常与定冠词the连用,做主语时,谓语动词常用第三人称单数形式。The population in China is much larger than that in America.2. 当主语表示"人口百分之几/几分之己"时,谓语动词常用复数形式。如: Over three fourths / 75 percent of this area's population are adults.3. have a population of 可以表示"有多少人口",a不能去掉。
