【选择题】有关It is high time that...句型

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！

Answer 1

答案选B.were
It is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。如：
　 It is time that the children went to bed.
　 It is high time that the children should go to bed.

Answer 2

选B
解析：It is high time that 这是一个虚拟语气的句型，后面的谓语动词有两种：1.动词的过去式2.should+动词原形，但是should不能省略；所以这个题应选B
翻译：该到了采取有效的措施才储备这个打乱的趋势的时候了

希望帮到你，祝学习进步

Answer 3

B
直接看后半句 effective measures（有效措施） ______ taken to reverse this disturbing trend.（扭转这一令人不安的趋势）
1. 措施是“被”采取（take）的 而不是主动者 应该用 take过去式的被动语态
2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词
3.measures是measure的复数
so B
