Question

—Do you know the young man well?
—Sure, we __________ friends since we met in Nanjing three years ago.

A．have been	B．were
C．have made	D．have become

Answer 1

A

試題分析：since引導時間狀語從句，常與完成時連用，since we met in Nanjing three years ago自從三年前在南京見面至今，是一段時間，要與延續性動詞連用。句意：你很了解這個年輕人嗎？當然，自從三年前我們在南京見面我們就成了朋友。故選A。
