20、t to go,were about,to go)out when it started to rain.,现在完成时,1.,概念：,表示发生在过去，持续到现,在，可能刚刚结束也有可能继续进行,下去的动作或状态，甚至延续到将来，,并对现在造成一定的影响或结果。常,与,since+,过去时（间）,for+,一段时间,连用。表示与现在有联系的过去的动,作。,2.,时间状语：,yet,already,just,never,ever,so far,by now,since+,时间点，,for+,时间段，,recently,lately,in the past,few years,etc.,3.,基本结

22、。,但是，非延续性动词的否,定形式可以表示状态的延续，可与,for/since,等时间状语连用。,有些同学错误地认,为这类非延续性动词不,能用于完成时态中。其,实，错误的本质在于非,延续性动词与时间段的,错误搭配，与现在完成,时态无关。,延续性语境中的非延续性动词的使用,在具体的语言环境中，往往会出现非延,续性动词与时间段相连用的情况。由于受,汉语影响，往往错误地直译为：,He has fallen asleep for an hour.,他睡了一小时了。（）,His father has died for three years.,他父亲去世三年了。（）,当出现这种情况时，我们往往采取以下解

23、,决方法：,（,1,）将非延续性动词转化为相应的,状态动词。所谓状态动词就是指这一,动作发生后接下来所呈现的状态。如：,He has been asleep for an hour.,（,fall,asleep,“入睡”为短暂动作，但,be,asleep“睡着”则为状态动词，可延,续。）,His father has been dead for three,years.,（,die,为短暂动词，“死”后的,状态可用“be dead”这种系表结构来,描述，可延续。）,常见的这种动词的转化有以下几类：,go there,be there,come back,be back,borrow,keep,

25、e,（,has,）,gone,的区别,have been to a place,意思是“到过、,去过”，表示曾到过某处，但现在,人不在那儿；,have gone to a place,表,示“去了”，已经去了某地，现在,人可能在去的途中或已经到那儿了。,1.,You have _ a tall young man.,A grown B grown into C grown us D grown up,2.He has _ the watch for a year.,A buy B bought C have D had,3.Has your brother _ the dog?,A kept
