it's high time that 后面可接两种形式,+sb did或者sb should（这个should不能省）,可为什么同样是这种句型的其他句子,should就能省略,比如it' a pity +that （should）+动词原型?,

It is (high)time (that)sb did/should do 是句型所要求的,无理由可讲；而It is a pity that...句型可以用陈述语气也可用虚拟语气,用should表示竟然,should可省略：
It is a pity that you didn't come.It is a pity that it comes at such a cost.
It is a pity that he （should ）give up this chance.真遗憾,他竟然放弃了这个机会.
It is a pity that such a thing (should) happen in your class.这种事竟然发生在你们班上,真是遗憾.

It‘s （high）time （that）sb did sth/sb should do sth什么意思 it's time that sb did sth,it's time that sb should do sth有没有 It is high time that sb.should do it's high time that后面用should do 和did 怎么选用 It is high time that sb.should do sth.中的should可省略吗 It is high time that sb did后面接动词什么形式啊?比如接go skating怎么接? it's requested that sb should do it is high time that +should do 与it is high time that +did的区形式主语加形容词加that后面要用虚拟语气吗.如It's important that sb should do和it' it's high time that sb were还是was It's (about / high) time that…… 谓语动词什么时候用did,什么时候用should do it's high time 句型中,从句中的谓语动词用过去式或should+动词原形 ,should不能省,shoul
