　　(1)It’s time for+n.该是（干）……的时候了 (2)It’s time+(for sb.) to do sth. 该是（某人）干……的时候了 (3)It’s time + that-clause 时，that可省略，time可由high,about修饰，从句中的谓语动词有两种形式：用动词的过去式(be用were)； 或者用should+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。 (4)It’s+ the+序数词+time +to do sth. 表示某人第几次做某事。

　　(5)It’s+the+序数词+time+thatclause.表示某人第几次做某事。
