Question

【题目】— 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

Answer 1

【答案】B
【解析】句意：－你的叔叔什么时候离开故乡的？－他离开将近二十年了。前句是一般过去时态，问的是叔叔离开的时间，用when提问；后句由for…可知句子用现在完成时态。leave是非延续性动词，不能与表示一段时间的for连用，表达成be away。故选B。
