447. It is time the authorities concerned took proper steps to solve the traffic problems.
该是有关当局采取适当的措施来解决交通问题的时候了。
六级词汇讲解:
It is time+某人+过去时从句，表示现在是该做某事的时候了。这个句型需要从句使用过去时表示虚拟语气，而主句it is则保持现在时态。如：It is time Mary (某人) thought (过去时，虚拟) about the future of you.（该是玛丽考虑你的未来的时候了）。the authorities concerned指“有关当局”。
句型拓展:
It is time for the whole society to care about our senior citizens.
该是全社会关注老年人的时候了。
It is high time that the article were published.
是时候发表这篇文章了。
v. 解决，解答
