Question

【题目】--Is Bohai Bridge open to the public yet?

--Yes．It ________ for almost one and half months．

A. has opened B. has being opened C. has been open D. was open

Answer 1

【答案】C

【解析】

句意“-渤海大桥已经向公众开放了吗？-是的，已经开放一个半月了”。根据 for almost one and half months可知，用现在完成时have/has done，且open为瞬间动词，要变成延续性动词，be+adj表示状态，故选C。
