表示“做某事的時機到了”的英語句型是什么呢？大學英語培訓的李老師告訴我們，可以使用“It's (high/about) time that...”這個英語句型，比如我們常說的“你該去寫作業了”或“我該去買雙 新鞋了”這種句子中都可以使用這個句型。
句型解析:
1.句型“It's (high/about) time + that...”是個常用句型，that引導的是從句，表示“該做……的時候了”，而實際上是意味著“早該做某事而沒有做”，所以從句需要用虛擬語氣來傳達一種遺憾 、急迫、批評、抱怨等情緒，多是在催促某人盡快做某事。從句的動詞形式要用一般過去式。有時，about和high可以省略。
例句：
It's about time you bought a new car.
你該買新車了。
It's high time you made up your mind.
你該做決定了。
It's time we ordered dinner.
我們該點菜了。
2.It is time + that + S + should + 動詞原形
此句型若加上助動詞should，則后面必須加動詞原形。
例句：
It is time that you should go to bed. = It is time that you went to bed.
你該去睡覺了。
情景模擬：
Wait a minute. Why I couldn't start my engine?
It's about time you bought a new car.
稍等一會兒，為什么我發動不了引擎？
你該買新車了。
It's time you had made a choice.
But I still can't decide which one I want.
你該做出選擇了。
但我還是無法決定我想要哪個。
It's time we ordered dinner.
Let's wait for Tom a little longer.
我們該點菜了。
讓我們再多等湯姆一會兒吧。
It's high time you made up your mind.
But I want to think all the projects over.
你該做決定了。
但是我想再把所有的方案好好考慮一下。
