There_ a lot of coal mines in the south,but many of them have been closed or are_ be closed.
A.use to having,about to
B.used to be,to
C.use to having,to going
D.used to be,supposed to
选了B,答案说是D,为什么捏= =
答
B/D都可以.题目设计有误.
而且这个or选择有逻辑上的问题.
除非这么改：or supposed to have been closed.对前面的说法加以纠正：南方过去曾有过很多煤矿,但是有许多煤矿已经关闭了或者以为已经被关闭了.
B.句意：南方过去曾有过很多煤矿,但是有许多煤矿已经关闭了或者将要关闭.
D.句意.南方过去曾有过很多煤矿,但是有许多煤矿已经关闭了或者估计将要关闭.（用应该讲,不合逻辑）
