5、 地点副词there/here/home/abroad前in省略 Tom has been in China for 2 years.I have been here since last week.英语动词根据词义可分为两种，一种是延续性的，一种是短暂性的。短暂性动词也可称为非延续性动词、终止性动词、瞬间动词，如:become,begin,buy,borrow,arrive,die,finish,get to know,go,join,marry,start,stop等。短暂性动词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一段时间的状语连用,如for+时间段、
