7、er a lot.Aposition BsituationCstate Dcondition答案：C3until的用法1)until和till用于肯定句中，主句的谓语动词必须是延续性动词，表示这一动作或状态一直延续到until/till所表示的时间为止。如live,wait,last,love,like,dislike,stay,work等。He watched TV until/till midnight last night.他昨天晚上看电视一直到了半夜。(until/till是介词)I waited for him until/till he came back.我一直等到他回来。(un

8、til/till是连词)2)until用于否定句中，其句型为not.until/not.till，意为“直到才”或“在之前不(没有)”，通常与非延续性动词连用，强调主句所表示的状态或情景到until/till所表示的时间才发生，主句必须是否定句，表示非延续性的动词有come,go,leave,meet,realize,understand,reach,get,arrive at等。He didnt go home until ten oclock.他直到10点钟才回家。(go home的动作是在10点钟才发生的)注意：until引导的状语从句可以放在句首，但till引导的状语从句则不可以。3)

9、until与否定词not同时位于句首时(not until)，主语和谓语必须倒装。Not until Sunday did he finish his work.直到星期天他才完成了工作。4)It was not until.是一个not until的强调句型。It is(was)被强调部分that其他部分。It was not until I got home that I realized I had lost my keys.直到到家了，我才发现我的钥匙丢了。(该句强调了not until I got home)其原句为：I didnt realize I had lost my key

10、s until I got home.注意：not until用于强调句式时，无论是until从句还是that后连接的其余部分都不用倒装，因为只有not until放在句首时，主句才倒装，而且连词that不可以省略。5)until引导的是时间状语从句，因此表达将来的情况应用一般现在时代替一般将来时。Well stay here until he comes back.我们要待在这儿，直到他回来。6)until只能指时间，不能指空间，指空间要用as far as。We walked as far as the end of the road.我们一直走到了路的尽头。高考直击(1)(2009江西)
