Question

How long have you been interested in collecting stamps?
Oh,my interest in that * my childhood.
A dates back to B dated form C dated back D dated back to
问：1.为什么用该时态?
2.date form 与 date back to

Answer 1

date back to可追溯到; date from从某时期开始(有)
语感稍有不同,前者和现在也有联系,而后者没有表明是否与现在有关.
例如:
This kind of music dates from the 18th century.
这种音乐可追溯到18世纪.
The church dates back to 1173.
这座教堂从1173年就已存在.
date back to = date from 追溯到 [只能用主动语态,不可用被动]
go back(to)回到某处
不一定是追溯,也可以地点上的回到go back to home回家
