题型：不详难度：来源：
Many things _____ impossible in the past are quite common today.| A．having being considered | B．considered | | C．are considered | D．considering |
|
答案
B |
解析
试题分析：句意：很多在过去被认为是不可能事情在今天很常见。此空位于things后，与things之间是被动关系，故用过去分词做定语。having being considered 用做状语，不做定语，故排除A。are considered 是谓语动词形式，故排除C；considering是现在分词表示主动，故排除D。故选B。
