China has a larger population than any other country.为什么country 后面没加has.

问题描述:

China has a larger population than any other country.为什么country 后面没加has.
不应该是China has a larger population than any other country has .

如果加has那么就要改成从句than that any other country has如果直接加has它后面少东西,而不加has这个句子是主谓宾都有的一个完整句子
