a few hours earlier和a few hours ago的区别

在新概念第二册的Lesson7里,有这么一段话,A few hours earlier, someone had told the police that thieves would try to steal the diamonds中A few hours earlier为什么不能用a few hours ago替换呢?这俩个短语有什么区别,分别用在什么情况下,

Too Late

a few hours earlier,时间段和earlier 一起使用,是以过去或将来某一个时间点为准的一段时间以前在本文中的意思可以扩展成下列句子 a few hours earlier than the time when the detectives were waiting at the airport.在侦探们等在飞机场之前的几个小时以前.

例如:When I got to school yesterday. I didn't see Jim. But one hour earlier, he told me on the phone he had been there.

当我到学校的时候,我没有看到Jim.可是(在我到学校)一个小时前,他在电话里说他在那里

a few hours ago 时间段和ago一起使用,指的是以说话时为准的一段时间以前.用在一般过去时

Now I am at home. But I was in the office three hours ago.

又例如:Oh?Why are you here so soon?I saw you in the market ten minutes ago.你怎么这么快就来了?十分钟前我还看到你在市场了呢.

本文中不可以替换,这课说的是钻石被偷换成石头和沙子,是以故事的形式表现的.全文用过去的口吻.第一句就看的出.The plane was late.所以从现在的角度叙述这个故事.一切的发生应该以故事中的过去的情景为时

间基点.

如果非要替换的话,可以替换成before,时间段和before 一起用表示的是以过去某一个时间为基准的一段时间以前.经常出现在直接引语改写成

间接引语题目中.

例如:He told me," I was here three days ago."改写成:He told me that he had been there three days before.

用了半个多小时回答你的问题,好辛苦.不求你采纳,但求能够帮助你.就象帮助我的学生们一样.

I was answering your question more than half an hour AGO.Till now,I have finished.About sixteen hours EARLIER,you had raised the question here.半个多小时以前,我在回答你的问题.到现在为止,已经回答完毕．你是在(我回答问题的)大约十六个小时以前提出这个问题的.

祝你英语蒸蒸日上!
