It's time后的從句用虛擬語氣
從句謂語通常用過去式表示現(xiàn)在或?qū)恚袝r(shí)也用過去進(jìn)行時(shí)或should+動(dòng)詞原形(較少見,且should不能省略),其意為(早)該干某事了。如:
I think its time you went to bed. 我想你該睡覺了。
Its time we went [were going, should go]. 我們該走了。
【注】(1) time前有時(shí)有about和high修飾。如:
Its high time you bought a new car. 你該買輛新車了。
(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(shí)而用were。如:
Its time I was in bed. 我該上床睡了。(不用were)
