D．have to work

Answer 1

C

試題分析：It’s high time that +…should do/did+其它 “是做…關(guān)鍵時(shí)候了”。That從句中要用虛擬語(yǔ)氣，特別注意should不可省。故選C.句意：隨著高考的臨近，是我們學(xué)生更加努力學(xué)習(xí)的關(guān)鍵時(shí)候了。
點(diǎn)評(píng)：虛擬語(yǔ)氣是高考必考點(diǎn)，用法較多，現(xiàn)將特殊的虛擬語(yǔ)氣結(jié)構(gòu)介紹如下：
（1）虛擬語(yǔ)氣用在狀語(yǔ)從句中由as if 或as though引導(dǎo)的狀語(yǔ)從句表示比較或方式時(shí)，從句中的謂語(yǔ)動(dòng)詞用虛擬語(yǔ)氣。動(dòng)詞形式用動(dòng)詞的過(guò)去式(be→were)或had+過(guò)去分詞。
如： The teacher treats the student as if he were her own child.
這位老師帶這位學(xué)生就象她的親生孩子一樣。
He speaks as if he had been to the United States.他說(shuō)得好象他真的到過(guò)美國(guó)似的。
（2）在It is time (that) …; I’d rather(that)…句型中從句的謂語(yǔ)動(dòng)詞常用動(dòng)詞的過(guò)去式表示虛擬語(yǔ)氣，意思是“該干某事了，時(shí)間已經(jīng)有些晚了”“我寧愿/希望”。
如： It is time that we did something to stop pollution.該我們做些什么制止污染的時(shí)候了。
It is time that Father picked up Lily from the kindergarten.該父親去幼兒園接莉莉的時(shí)候了。
I’d rather you told me the truth.我真希望你告訴我真相。
I’d rather I didn’t see you again.我寧愿不再見(jiàn)著你。
