A taped message from his mother plays in the background. At firstJimy had played the records everyone played in those days.
请老师翻译一下这个句子。
另外，请剖析一下：
为何先做的动用途一般过去时，而后发生的动作却用过去完成时?
A taped message from his mother plays in the background. At first Jimy had played the records everyone played in those days.
1. 第一句描述的情景与后面句子无关。句子用一般目前时，类似戏剧、场景的 “旁白；解释说明”。一般用括号标出。
2. 第二句进入描写当时的状况。Jimy had played the records 用过去完成时，表明参照另外一个动作或事件（比如，在主持发言之前，在会议召开之前等），也就是说，它的参照物不是定语从句everyone played。
3. 两个时间状语有哪些用途：
定语从句的时间状语是 in those days， 跟 played 连用，说明是过去习惯性动作。也就是说，当时大家常常播放这类唱片。
at first 这个时间状语，也提供了一个要紧信息：说明在做某事之前，第一做了哪些，比如上面括号里的内容（在主持发言之前，在会议召开之前等）。符合过去完成时 “过去的过去” 特点。
4. A taped message from his mother plays in the background. At first Jimy had played the records everyone played in those days.
【翻译】背景里播放着他妈妈的录音信息。刚开始，吉米播放了当时大伙都在播放的唱片。
