-- ______did your uncle leave his hometown ?--He ______ for nearly twenty years.A.When, has left | B.When, has been away | C.How long, has left | D.How long, has been away |
|
答案
B |
解析
试题分析:when什么时候;how long多长。句意:你的叔叔什么时候离开的他的家乡?——他大概离开将近二十年了。Leave是瞬间动词,不能和表示一段时间的时间状语连用,结合语境可知选B。 点评:完成时态中的动词有瞬间动词和持续性动词之分,瞬间动词的过去分词强调的是动作的完成,持续性动词强调的是动作的持续性。现在完成时态中表示一段时间的时间状语不能和瞬间动词连用,持续性动词不能和表示瞬间时间的时间状语连用,需注意区分。 |
