现在完成时的主要用法
一.表示过去发生或已完成的某一动作对现 在造成的影响和结果。常与不确定的时 间状语连用，如:already, never, ever, just, yet, before, 等, He has just turned off the light.
相于：He turned off the light just now. The light isn’t on now.
8.Sally’s never seen a play in the Shanghai Grand
B Theatre, ______?（上海高考）
A. hasn’t she B. has she
C. isn’t she D. is she 解析：句中出现了否定副词never,因此这是一个否 定句，故在变反意疑问句时要用肯定形式，故可排 除A、C；又因为Sally’s是Sally has的缩写，即是现 在完成时态，故选has she。
第一句用现在完成时时态，意为：“He bought
an English-Chinese dictionary. And he still has it” “过去他买了一本英汉字典，现 在他还有这本字典” 。 第二句用过去时只叙述过去他买过一本英汉字 典这一事实，至于现在他是否有这本字典并未强 调说明。
borrow, arrive, come/go, die, fall, finish, get to know, join, leave, marry 等。
●为了表述这种意思，我们常用相应的延续
性动词”来代替短暂性动词.（如下表）
