一般过去时，仅仅表示在过去某一时刻曾发生过这一动作，与现在无关。他已学英语五年了。HehasstudiedEnglishforfiveyears.

他曾学过五年英语。

HestudiedEnglishforfiveyears.

（说明他还继续学下去）（只说明他过去学过五年英语，但现在不学了。）一般过去时与现在完成时有一些明显的时间状语。遇到yesterday,Lastyear,inMay,in+过去某一年，twodaysago,theotherday,justnow等就用一般过去时

当有already,yet,

sofar,inthepast/lastfewdays(在过去/最近的几年里)，since接过去时间状语或过去时的句子等常用现在完成时
