有时population可用作可数名词,其前可用不定冠词.例如:
China has a population of about 1.3 billion.(=There is a population of about 1.3 billion in China.) 中国大约有十三亿人口.
这边的用法和例句相似.有没有用复数的例子给我看看啊,,,,,谢谢..用法如下：在表示多个地区的人口时,population要用复数形式populations。例如:Many parts of the world, which once had large populations and produced plenty of crops, have become deserts. 世界上很多地区一度人口众多,种植大量的农作物;现在,这些地区已经变成了沙漠。啊,电脑有点卡....好了,我再把这个弄成满意答案////..
