The difference btw “be dated back to” and “ date back + time” ?
答案是B，我选的D，“be dated back to” and “ date back + time” 的区别是？我知道D在having上出错了

（B） the use of fire to cook food 做后面两个分句的主语，逻辑清晰。举例时用 as 而不用 like
（D） 主语成了fire了，而不是the use of fire to cook food，逻辑意思错误。Having的用法不对。

另外，关于date的用法，主要有：date back，date back to，date from三种，不存在be dated back to这种被动形式，date表“追溯”意思时，只有主动形式。

date back是个动词短语，后面接时间段，有to的话后面得接时间点。ago是副词，一般用在时间段之后，表示“……多长时间”以前

1. date back 后面加一段时间
通常翻译成： 发生在****年（月、天等）前
如：This story dates back 200 years。故事发生在200年前。

2. date back to 后面加某一个过去时间的具体时点
通常翻译成： 发生在过去****的时候
如：The church dates back to 1173. 此教堂建于1173年。
      The town dates back to the Tang Dynasty. 这座小镇建于唐代。

This custom dates back to the 17th century，but this church dates back 8 centuries.
这种风俗开始于17世纪，但这个教堂建于8个世纪前。

such as 不是应该连用吗，原来还可以分开后表示举例。
