That 和 That one 的区别是什么?eg:1)The bridge made of stone is stro

that是那,和this“这”相对.
例如：
This is my home.That is my neighbours.
这是我的家,那是我邻居的家.
That one是短语,指“那一个”.例如：
This applicant is by far the better than that one.
这个申请者远比那一个好.
所以：
1)The bridge made of stone is stronger than( that) mad.的意思是：石桥比泥土桥要结实.
2,The bridge is 3 times as long as (that one .)的意思是：这座前比那座桥长三倍.
第一句说的是属性,属于内部的比较；第二句是两座桥的比较.
Their Houses are too big ,so i want to buy one.
他们的房子很大,所以我想买一座.
这里应该用ONE.因为theri houses,表示的是多个房子,买其中一个.应该用one.
