虚拟语气中常用过去表示现在,过去的完成时表过去,其实语法没那么多讲究,只是人们习惯用语罢了,你只要明白他要表达的意思就OK了,在与外国人交流时 他们并不注重这些,语言只是沟通,你现在学的这些在实用中没多大意义,除了应付考试。 It is high time that 后固定跟过去式,表示“现在是时候做XX了。”Eg:It is high time we began to work.我们该开始工作了。同时也有 It is high time to do sth.这时句子就简单了。
而 在It was high time that句型后,同样是跟过去式,表示“在XX时候该做XX”一般会有个时间状语或能表明时间的成分在句中表示“XX时候”Eg:Peter's suit was old and it was high time he bought a new one. 看,此句中前面个分句中的WAS 明确表示了时间是在过去,所以此时后面也要跟WAS而非IS。 再举个例子,It was high time he called his wife then.句中的then 也突出了那时,而非现在。
1.it is high time+ 主语+shuold do 或者 did 形式谓语动词。例如 it is high time you worked hard at your homework. it is high time you should work hard at your homework.(should不可省略)翻译:你(现在)真该努力写作业了。 2 it was high time + 虚拟句子结构相同。但成翻译--那时某人真该做某事。

1.is-表现在时was-表过去时eg:It's time he went home/It was time he went home yesterday.2.可以.如果过去式与should do同时出现,要以过去时为主3.即表将来又表现在
