not.until句型和it’s time to句型 【原句呈现】I did not realize schools in the UK are so different from schools in China until I read your article.(P5)直到我拜读了你的文章，我才知道英国的学校与中国的学校是如此的不同。 【句法分析】“not...until”基本意义为“直到……才……”。“until”既是介词，又是连词，因而该结构可以用于简单句中，也可以引导一个复合句。 I didn’t receive your letter until yesterday.直到昨天我才收到你的来信。 I didn’t know his name until he told me. 直到他告诉我，我才知道他的名字。 【考点聚焦】①Not until…＋主句 (倒装句) ②It is/was not until…that… (强调句型) 【考题研读】单项选择题 ①Not until he left his home _______ to know how important the family was for him. A. did he begin B. had he begun C. he began D. he has began 【答案与解析】A。not until所引导的状语(从句)放在句首要用部分倒装。句意：直到他离开家，他才知道家对他来说是多么重要。 ②It was not until I came here _______ I realized this place was famous for not only its beauty but also its weather.A. who B. that C. where D. before 【答案与解析】B。把it was及空去掉，可转换为一个完整的句子。且这是表示“直到……才”的强调句型：it was not until … that …。句意：直到我来到这儿才意识到，这个地方不仅以它的美而且以它的天气而出名。 句型it’s time to so sth.句型 【原句呈现】Now it is time to present your poster to the class.(P19)现在是你向全班同学展示海报的时候了。 【句法分析】“it’s time to do sth.”意为“是该做某事的时间了”。为了表达“是某人该做某事的时间了”可以用下列句型：It’s time for sb. to do sth. 或It’s (high) time that sb. did/should do sth. 请注意不要与下列句型相混淆： It’s + the (one’s)+序数词+ time +to do sth.(或+that clause)表示某人第几次做某事。 这是我第一次用英语写信。 It is my first time to write a letter in English. It is my first time that I’ve even written a letter in English. 【考点聚焦】It’s (high) time that...中的that从句谓语动词的形式：可以用过去式“did”，也可以用“should +do”，但要切记住“should”是不可以省略的。 【考题研读】单项选择题 ①Jack is a great talker. It’s high time that he _______ something instead of just talking. A. will do B. has done C. do D. did 【答案与解析】D。在“It’s high/very time that…”句型中，从句中的谓语动词用did或should do，故选D项。句意：杰克是个善于夸夸其谈的人，该是他做点什么而不是仅仅说说而已的时候了。 ②Don’t play any longer. It’s high time you _______ down to your study. A. get B. to get C. shall get D. should get 【答案与解析】D。见上题的解析。句意：不要再玩耍啦！是该你学习的时候了。
