It's time…句型是中學(xué)英語里使用頻率較高的句型,其意為“該是……的時(shí)候了”.用法靈活多變,也是大家以掌握的句型.現(xiàn)就其有關(guān)句式歸納如下：
⑴ It's time for + n.“該是（干）……的時(shí)候了.”例：
Boys and girl, It's time for class.
同學(xué)們,該上課了.
⑵ It's time + (for sb.) to do sth. .表示“該是（某人）干……的時(shí)候了.”例：
It's time for you to clean the classroom.
該是你打掃教室的時(shí)候了.
It's time to go to school.
該去上學(xué)了.
⑶ It's time + that clause 時(shí),that可省略,time可由high,about修飾,從句中的謂語動(dòng)詞有兩種形式,或者用動(dòng)詞的過去式(be用were)；或者用shoud + 動(dòng)詞原形（should不能省略).此句型為虛擬語氣句型,表示“現(xiàn)在某人該做某事了”.含有該事早該去做而未做,現(xiàn)在去做似乎都為時(shí)已晚的意思.例：
It's time （that）we went to bed.
我們?cè)撊ニX了.
It's high time that the article were published.
發(fā)表這篇文章是適時(shí)的.
It's time you should do cleaning.
你該去打掃衛(wèi)生了.
⑷ It's + the/序數(shù)詞+ time +to do sth. 表示某人第幾次做某事.例：
It is my first time to write letter in English.
這是我第一次用英語寫信.
⑸ It's + the+序數(shù)詞+ time+ that clause.也 表示某人第幾次做某事.例：
It is my first time that I've even written letters.
這是我第一次用寫信.
句型⑷ 句型 ⑸ 可以互換.
