【选择题】有关It is high time that...
It is high time that effective measures ______ taken to reverse this disturbing trend.
A.be B.were
选哪个,请说明理由谢谢!

B
It is high time +一般过去时的从句,固定用法,表示已经到......时候了。

这个肯点选A了,一看就是标准的虚拟句+被动句,很简单的,如果错了你劈死我。。

问题补充: 1.补充:这个句型“it was time+从句(过去完成时)”,请举It is high time that we should leave. 是我们该走的 时候了 It was

It is high time that 早就应该。。。了,后面用虚拟语气,所以选were

B
虚拟语气还可用在定语从句中,表示:“早该做某事了”时,定语从句中的谓语动词须用虚拟语气,其虚拟语气的结构为:It is (high / about) time that + 主语+ 动词的过去式/ should + do(优先使用动词过去式),即从句用虚拟过去式
