这个能有为什么呢?无非是population的常用句型而已
即：the population of sp is + 基数词 = Sp + has a population of + 基数词
sp指some place,意思是“某处/某地”.
还可以变成如果固定句型：
There are + 基数词 + people + at/in/on + sp 或 There is a population of + 基数词 + at/in/on + sp
如此句还可以变成：
There are 20,000,000 people in Malaysia.
或者：There is a population of 20,000,000 in Malaysia.
