这两句话哪句对？说明一下？感谢

Hi

两句话都不对！

英语中倍数词的表达方法：

1．A is +倍数词+ as +adj./adv.原级+ as +B
2．A is +倍数词+ adj./adv.比较级+ than +B
3．A is +倍数词+ the+ 度量名词(size, weight, height, depth, width, length) +of +B
正确表达应该如下：
The population of America is 15 times as large as that of Australia.
The population of America is 15 times larger than that of Australia.

Tks!

第二句是正确的。

第一句是对的
