英语老师说：It is time that sb did sth.该是某人做某事的时候了。

你好！

恐怕我得说：你说的不对！

首先， It is time that sb did sth. 这本身就是定语从句。这个句式也不适合改为强调句。

其次，time的常用句型有：

It is time to do sth

It is time for sb to do sth

It is time for sth

It is time( that) sb did sth

should do sth 最后这两种形式，都是表示虚拟语气的句式。

例如：

It is time that I worked harder for my dream.

=It is time that I should work harder for my dream.

该是我为我的梦想而努力的时间了。（表示“幡然悔悟，早该努力”）。

最后，对比强调结构：

It was at six o'clock yesterday时间状语，被强调部分 that I met him at the school gate.

It is him that /whom I met at six o'clock yesterday at the school gate.

祝你开心如意！
