一般过去时与现在完成时的区别
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 …
现在完成时中延续性动词和终止性动词
英语动词根据词义可分为两种，一种是延续性的，一种是终止性的。终止性动词也可称为非延续性动词、瞬间动词或点动词，如: becme, begin, buy, brrw, arrive, die, finish, get t knw, g, jin, marry, start, stp等。
终止性动词表示动作的发生与结束于一瞬间完成, 不能再延续, 所以它的现在完成时不能和表示延续的时间状语连用, 即不能与表示一段时间的状语, 如fr + 时间段、 since + 时间点 / 从句连用, 也不能用在hw lng引导的特殊疑问句。
若保留fr + 时间段, since + 时间点 / 从句, 或用在 hw lng句型中, 则需将终止性动词改为相应的状态动词或延续性动词。
以下是常用的瞬间性动词和延续性动词转换对应表: cme —be here buy —have brrw —keep leave —be away die —be dead stp —be ver begin / start —be n
