it is time that we should do something for our country.关系词为何用that
It's time + that 是固定句型,that可省略,time可由high,about修饰,从句中的谓语动词有两种形式,或者用动词的过去式(be用were);或者用shoud + 动词原形(should不能省略).此句型为虚拟语气句型,表示“现在某人该做某事了”.含有该事早该去做而未做,现在去做似乎都为时已晚的意思.

it is time + that 这是句型, 某人该做某事了
从句中用虚拟语气 sb. did.. 或sb. should do

that加从句,不过也是可以省略的,做题目的时候没多大影响
