英语高频语法小专题考点讲练系列十 现在完成时
一、现在完成时定义:
现在完成时用于表示过去的动作或状态持续到现在,或对现在造成的影响,或动作可能持续发生下去。
二、现在完成时时间状语:
already已经(放肯定句中或句尾)、yet尚未(放否定句和疑问句句尾)、ever曾经(放句中)、never从不(放句中)、just刚刚、before之前、so far至今为止、how long多久、次数、for+一段时间、since+时间点。
三、现在完成时的结构:
主语+助动词(have/has)+动词的过去分词(done)
四、注意:
(一)has gone to:表示某人已去了某地,而没有回来(去了没回)(不可与 for+一段时间 连用)
has been to :表示去过某地(去过已回来)(不可与 for+一段时间 连用)
has been in/at(in表示相对大一些的地点;at表示相对小一些的地点):表示一直呆在某地, 常与时间段搭配(呆了很久)。
e.g.:He has gone to Beijing. (去了北京)
He has been to Beijing. (去过北京)
(二)现在完成时与延续性动词
①延续性动词:表示的动作是能延续的动作,这种动作可以延续下去或产生持久的影响。
e.g.:learn\ work\ stand\ lie\ know\ walk\ keep\ have\ wait\ watch\ sing\ read\ sleep\ live
②终止性动词:也叫非延续性动词,瞬间动词,一次性动词。表示的动作不能延续,即动作发生后立即结束,产生某种结果。在有了某种结果后,动作就不能再继续下去。
e.g.:leave\ start\ set out\ arrive\ reach\ get to\ begin\ stop\ shut\ turn off\ marry\ put\ put on\ get up\ wake\ fall\ join\ meet\ receive\finish\ end\ complete\ become\ come\ go\ die\ open\ close\ break\ give\ jump\ buy\ borrow
Attention:终止性动词不能和一段时间状语连用。
终止性动词转换为延续性动词:
①come/arrive/get to/reach → be here ②leave/go →be away ③begin/start →be on
④open →be open / close → be closed ⑤die →be dead ⑥finish/end→ be over
⑦join → been (in). ⑧buy /catch → have ⑨borrow → keep
其他:break → be broken get up → be up marry → be married become → be lose → be lost
