A few hours earily 与A few hours ago区别

1. a few hours ago是指“以现在/直接引语时说话之时为准，在这之前的几个小时”,带有该时间状语的句子只能用一般过去时或过去进行时
如：He was here a few hours ago.
He said, "I was playing basketball a few hours ago."
2. 楼主应该是打错了吧，因为early本身可做形容词和副词，绝对没有什么earlily的单词。
如果是A few hours earlier 的话，则其动作所发生时间的计算是相对于另外一个动作而言“更早几个小时”，而并不是以现在或当时某个时间（说话人说话的时间）为准来计算，带有这样成分的句子的时态使用一般没有限制。
如： He got up a few hours earlier than I.
He'll always get up a few hours earlier than I in future, I think.
He said he had finished the job a few hours than I.

前者是指早几个小时,而后者是几小时以前.
eg:You should be there a few hours early.
I saw him a few hours ago.
