一、基本用法
從句謂語通常用過去式表示現(xiàn)在或?qū)�，有時也用過去進(jìn)行時或“should+動詞原形”(較少見，且should不能省略)，其意為“(早)該干某事了”：

二、同義表達(dá)

三、兩點(diǎn)說明
(1) time前有時有about和high修飾：
It’s high time we left. 我們早該動身了。

I think it’s high time that she made up her mind. 我想她該拿定主意了。

(2) 與其他的虛擬結(jié)構(gòu)不同，該結(jié)構(gòu)不能在該用 was 時而用 were：
It’s time I was in bed. 我該上床睡了。(不用were)
