B. are put
C. will have been put
D. are being put
题目解答
答案
B. are put
解析
步骤 1:理解句子结构
句子的主干是 "it will still be some years before all the metro lines in Suzhou _____ into operation.",其中 "it will still be some years before" 是一个时间状语从句,表示在某个时间点之前还需要一些年份。
步骤 2:分析时态
由于 "it will still be some years before" 表示将来的时间,因此主句中的谓语动词需要使用一般现在时来表示将来发生的动作。
步骤 3:分析语态
"metro lines" 和 "put into operation" 之间是被动关系,因此需要使用被动语态。
