the population of tianjin is smaller than ______ of shanghai .1.it 2.that 3.this 4./

问题描述:

the population of tianjin is smaller than ______ of shanghai .1.it 2.that 3.this 4./

选2,代替上文中提到的,用that.看不懂后面的of shanghai 、请问可以改成 in shanghai 吗?不能,前面是用的是of,后面也要用of,其实完整的句子是:the population of tianjin is smaller than the population of shanghai .为了避免累赘,用that 代替前面提到过的。
