请问：
1.虚拟语气的句型“it is (high)time that”和“it was (high)time that”在句子表达的意思上有什么不同?请区别性举例,
2.这个“it was (high)time that”句型的从句谓语可以是过去式或should+动词原形吗?可以的请写出例句.
如果“should+动词原形”可以,那么它是说明现在还是将来?请写出例句.
答
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。
答
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
答
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,...
