have been t & have gne t 区别
have / has been (t) 表示“曾经到过某地”，说话时此人不在那里，已经回来。侧重指经历。have / has gne (t) 表示某人“已经去某地了”，说话时此人可能在路上或已到那里，反正不在这里。
【温馨提示】1. have / has been t常与ever, never, nce, twice, hw many times等连用。 e.g. I have never been t America, s I hpe t g there ne day.
2. have / has gne t常用于含有sb. is ut, sb. isn’t in (...)等暗含某人不在说话现场的语境中。 e.g. Our math teacher isn’t in his ffice. He has gne t the meeting rm.
3. 当have / has been t 中的t后为表示地点的副词there, here等时，t要省略。 e.g. I wn’t g t the new park because I have been there twice.
根据语境，用have / has been (t) 或 have / has gne (t)填空。1. —Hi, this is Dave. May I speak t Jim? —Srry, he isn’t in. He ______________ the schl library.
has gne t

一般过去时与现在完成时的区别
① 一般过去时只强调过去的动作；现在完成时强调过去的事情对现在的影响。② 一般过去时通常与表示过去的时间状语连用；现在完成时则不能与表示过去的时间状语连用。③ 一般过去时单纯表示过去的经历；现在完成时表示过去的动作或状态延续到现在并可能持续下去。
一般过去时的时间状语有：yesterday, last week, … ag, in1980, in Octber, just nw … 共同的时间状语有：this mrning, tnight, this summer, befre, already, …　 现在完成时的时间状语有：fr, since, ever, never, just, already, yet, in past years …
