现在完成时

现在完成时

一概念：表示动作发生在过去，目前可能已经完成或还在继续，强调动作对现在产生的影响或结果。

结构：主语+have/has+动词的过去分词+其它 二用法：

1． 表示动作发生在过去，强调对现在产生的影响或结果。常与

just,already,ever,never,yet,before等到副词连用。 My father has gone to Shanghai.(表示人不在这里) I have had supper.(我现在不饿了) She has just finished her homework.

2． 表示动作发生在过去，一直持续到现在，也许还要持续下去。常与since,for 连用。 Since+时间点 for+时间段 He has lived here since 1980.

My brother has been a soldier for two years.

She has learnt English since she was four years old.

3． 动词一般都可以构成完成时态，但非延续性动词在肯定句中不能和表示一段时间的时间

状语连用。(for,since)

常用非延续性动词有：come,go,,join,start,begin,leave,arrive,lend,borrow,give,see,hear, finish,find,die, close,open 等。 功记10个瞬间动词顺口溜：

开始离去，借来还，出生入死，买到家 各词改为相应的延续性动词为：

Begin---be on leave----be away from borrow-----keep go-----be off Come----be here return-------be back join------be in die-----be dead Arrive----- be here

如：His grandpa has been dead for five years. 同义句： It is five years since his grandpa died. His grandpa died five years ago.

Five years has passed since his grandpa died. 4.have/has been to与 have/has gone to 区别

have/has been to表示某人的经历，意为“曾经去过某地”，说话时，此人在本地。可与once,twice,several times, just ,ever,never 等副词连用 I have been to Beijing twice.

Have you ever been to the Great Wall?

have/has gone to意为“去了某地”表示说话人不在说话现场，可能在路上，也可能已到达所去地方。

His teacher has gone to America.
