that 和one 的区别

Is family life in theUS quite different from __in your country ？
---yes i think so . i've noticed a few differences.
A one B what C that D those\
为什选ONE 不用THAT

答案one错误，that才是正确答案。

解释：
1. those = the ones，指代名词复数，排除D；
what不能用作指示代词，排除B。
2. one指代泛指的可数名词单数。
而that有两种指代用法：
1）指代不可数名词
2）指代特指的可数名词单数，且此时that = the one.
3. 此题中，family life应该是不可数名词，所以只能用that来指代。

估计是楼主看错了答案或答案印刷错误，要相信自己哦。
