It is (high) time that表示“是該做......的時候了。后面的從句謂語動詞要用過去式或用should加動詞原形，但should不可省略。例句：It is high time that we should tell him the truth.是我們該告訴他真相的時候了。

It’s?high/about/good?time?that+從句句式的用法

這種句式常用it作形式主語，that從句為主語從句，句中常用一般過去式或“should+do”的虛擬語氣結(jié)構(gòu)。注意：其中should不可省略;?time前不加定冠詞the.?

結(jié)構(gòu)：It’s?(high/about/good)time?that?sb?did/should?do?sth

例如：是時候為夢想拼搏奮斗了。It’s?high/good/about?that?we?struggled/should?struggle?for?our?dream.?

練：瑪麗是個空談家，是她該做些什么，而非空談的時候了。Mary?is?a?great?talker.?It’s?high/about/good?that?she?______?something?instead?of?just?talking.

答案：did/should?do
