4. 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begin,start,die,buy,leave, come等,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,for+时间段, since+时间点/从句连用,也不能用在how long引导的特殊疑问句
初中英语课本中常见终止性动词有:leave, go, come, arrive, begin, buy, borrow, die, join, , 可用以下方法:               
⑴.将时间状语改为时间段+ ago,句中谓语动词用一般过
去时. 
. My brother joined the army two years
ago.               
⑵.若保留for+时间段,since+时间点/从句, 或用在 how long
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
come/go/arrive/get/reach/move------be in/at
open-----be open
die------be dead close----be closed
e---be borrow---keep
begin/start-----be on put on----wear
leave-----be away (from) buy-----have
