Question

【题目】How long his grandfather _ ?

A. has, died B. has, been death C. has, dying D. has, been dead

Answer 1

【答案】B

【解析】句意：他的爷爷去世多长时间了？has died已经去世了；has been death形式错误，death是名词；has dying形式错误；has been dead已经去世了。句中How long问的是一段时间，die是瞬间性动词，不能和一段时间连用，故A不对。has been dead是一个系表结构，表示状态，可以持续。故应选D。
