一般要說 ”現在是該(做)...的時候” 是用 It's time to V / It's time for N 的句型 比如: It's time to get up. / It's time for dinner. 但是要在 It's time ... 的後面接子句的話, 要注意這個子句會用過去簡單式 比如要說: It's time (that) you grewup. (你該長大了) 而不是 It's time (that) you growup. 在這種句型裡其實是一種和現在事實相反的假設 因為這樣講通常是指對方現在其實 沒有這麼做 所以和 if 的句型一樣, 和現在事實相反的假設用過去式表達 It's time ... 也可以用 It's about time ... 或 It's high time ... (早該是...的時候了) 例如: It's about time (that) he told the truth. It's high time (that) the government took care of this problem.
