第一个空用现在完成时,表示事情对现在有影响,考时态的差别.
第二个空应该用虚拟语气,固定句型 It is the (high)time that.
选A
个人见解~o(∩_∩)o~

A。第一空用现在完成时表示已经造成的结果,所以要采取必要的措施。第二句中用了固定句式:It's time that后接虚拟语气,用一般过去时表示现在或将来发生的事。

选b,后面的空是 It is the time that +did的句型,所以排除c,d,前面如果是完成时应该是对现在造成的影响和结果,并未涉及结果。

选A
第一个空 是考察现在完成时,表示动作发生在过去,但强调对现在的影响,例如Who has broken the window?
第二个空 是考察句型 It is time that...句子必须用一般过去时,这是虚拟语气的一种,您可以看看英语语法说虚拟语气篇章肯定有收录这条讲解。 例句, It is time that we had class.(到上课的时间了)...
