A. when B. than C. until D. after 1. 【答案】A 【解析】根据主从句的动词时态可知主句谓语动词的动作在从句谓语动词之前已经完成, 引导词的意思是: 当??的时候, 选 A。 2.【答案】A 【解析】此处是 as 引导这个时间状语从句,这里 smile 和 apologize 同时进行,as 意为:当?的时候。句意:当 玛丽为她喝醉了朋友道歉时,他礼貌地微笑着。 3.【答案】D 【解析】“It is + 时间段 +since + 从句(谓语为一般过去时)”为固定句型,故答案选 D。句意为:“正如所 报道的那样,自从清华大学建校以来已有 100 年时间了。” 4. 【答案】C 【解析】所填词引导状语从句, 构成 It(will)be+时间段+状语从句, 意思是:过多久才将......, 选 C。 5.【答案】A 【解析】此题较易。只要辨认出固定句型 hardly?when?问题即刻解决。句意:我刚到办公室,我妻子就给我打 电话让我立刻回家。 【考点定位】考查固定句型 hardly?when?的用法。

A. since B. that C. when D. until (2)从属连词 while 引导的的动作必须是持续性的,不能和瞬间性动词连用。侧重主句动作和从句动作相对比。 Please don't talk so loud while others are working .别人在工作时,请别高声谈话。

A. while B. until C. when D. before 5.(2009.辽宁高考) It just isn’t fair_____ I was working as a waiter last month; my friends were lying on the beach. A whenever B. though C. for D. while (3) as 引导一个时间状语从句,其动作为持续性动作,多用于主句和从句动作交替进行或同时发生,可翻译为 “一边??,一边??”或者“随着时间的推移”。 As time goes on ,it's getting warmer and warmer.随着时间的推移,天气越来越暖和了。 As the time went on,the weather got worse.(as 表示“随着??”之意) The atmosphere gets thinner and thinner as the height increases.随着高度的增加,大气越来越稀薄。 As years go by,China is getting stronger and richer.随着时间一年一年过去,中国变得越来越富强了。 He hurried home, looking behind as he went. She wept as she spoke.她边说边哭 He looked behind from to time as he went.他一边走,一边不时地往后看 高考链接: Jenny was very sad over the loss of the photos she had shot at Canada, _____ this was a memory she especially treasured.(06 广东) A. as B. if C. when D. where (4)如果主句表示的是短暂动作,而从句用延续性动词的进行时态表示在一段时间内正在进行的动作,此时 when, while 与 as 可互换使用。 He fell asleep when [while, as] he was reading.(read 为延续性动词)他看书时睡着了。 When /While /As we were dancing,a stranger came in.(dance 为延续性动词)当我们跳舞时,一位陌生人走了 进来。 When /While /As she was making a phone call,I was writing a letter.(make 为延续性动词)当她在打电话 时,我正在写信。

When/While/ As I was walking down the street, I came across an old friend of mine. (二)Before 和 after 表示“在?之前(或之后)” 这两个连词大家貌似很熟,但其实是历年高考中大家最容易犯错的两个连词。例如可以试问自己下:before 后面 接先发生动作后发生动作?after 后面接先发生后发生?摸清动作发生的先后顺序。牢记‘前’(before)接后, ‘后’(after)接前 这样的口诀。 (三)Before 和 Since (1) before 有时可译为“还没??就“。 He had measured me before I could say a word. 我还没来得及说话.他就给我最好了尺寸。 I hadn't waited long before he came. 我还没等多久他就来了。 I slipped out before the lecture started. 还没等讲座开始我就溜了出去。 before 也可用于 it 结构,与 since 结构比较相似,注意它们所用时态的区别。 其结构是:It will be + 段时间 + before sb. does sth.表将来 或 It was + 段时间 + before sb. did sth.表过去 常译作“还要多久才??”。 He is leaving for Australia and it will be three years before he comes back. 他要去澳大利亚了,3 年 后才会回来。 During the war he joined the army and it was three years before he came back. 战争期间他参了军,3 年 后才回来。 (2)Since 自....以来 1)若 since 引导的状语从句的谓语动词是终止性动词(如 go,come,leave,start,begin 等)的过去时,则从句 表示的时间是“从该动作开始的那一时刻起”。这是最常见的一种用法。 He has studied very hard since he came to our school.自从来到我们学校, 他学习就非常努力。 Great changes have taken place in our school since you left.自从你离开这里, 我们学校发生了很大的变 化。 2) 若 since 引导的状语从句的谓语动词是持续性动词或表示状态的静态动词(如 live,stay,study,learn, smoke, be 等)的过去时,则从句表示的时间是“从该动作或状态的完成或结束时算起”。 I haven’t heard from him since he lived here.从他不住这儿起, 我一直没有收到他的信。 I haven’t eaten snakes since I was a student at school.was 表示状态 I haven’t eaten snakes since I left school.自从我毕业后就一直没吃过蛇。 试比较: He has written to me frequently since I was ill.自从我病愈以来,他经常给我写信。(从句谓语为状态动词) He has written to me frequently since I fell ill.自从我生病以来, 他经常给我写信。(从句谓语为终止性 动词) 3) 若 since 引导的状语从句的谓语为持续性动词或静态动词的现在完成时,则表示动作和状态延续到现在(说话 时刻), 其表示的时间的起点应从动作发生之时算起。 He has written to me frequently since I have been ill.这里 have been ill 表示状态的持续性,时间的起 点应从:“开始生病”时算起。“自从我生病以来, 他经常给我写信。” 试比较: I’ve written her 20 letters since I have been here.自从我来到这,我已经给她写了 20 封信。 (从开始算起)

I’ve written her 20 letters since I was here.自从我离开这儿,我已经给她写了 20 封信。 (从结束算起) 4) It is + 段时间 + since sb. did sth. It has been + 段时间 + since have done sth. 表示“从??起已有多长时间了”。 两句型意思相同, 前者是规范说法, 后者是口语说法。 用法:since 从句中常用一般过去时,若从句中是持续性动词的一般过去时,则表示该动作结束有多长时间了。 It is three years since he smoked.他不吸烟已有 3 年了。 试比较: It is three years since he began to smoke. It is three years since he has smoked. 两句均意为:他吸烟已有 3 年了。 注意:在这种结构中,since 引导的从句绝对不能用否定式的谓语动词来表示否定意义, 试比较:他好久没学汉语了。 误:It is a long time since be didn’t study Chinese. 正:It’s a long time since he studied Chinese. (studied 为持续性动词, 应从其动作结束时算起) (四)Till,until 和 not?until 无论肯定句还是否定句,until 的意思都是“过则反主”,即“过了从句所发生的动作后,则发生与主句相反的动 作”。 The baby won't stop crying until his mother tells him a story. 过了他妈给他讲故事这个动作时间,小孩儿就停止哭泣了,但主句说不会停哭,所以选择 until。 1)肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。 肯定句:I slept until midnight. 我一直睡到半夜时醒了。 2)否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可以。 否定句:She didn't arrive until 6 o'clock. 她直到 6 点才到。 Don't get off the bus until it has stopped. 公共汽车停稳后再下车。 I didn't manage to do it until you had explained how. 直到你教我后,我才会做。 3)区别:until 可用于句首,而 till 通常不用于句首。 Until you told me, I had heard nothing of what happened. 直到你告诉我以前,出了什么事我一点也不知道。 4)否定句可用另外两种句式表示。 Not until?在句首,主句用倒装. Not until I began to work did I realize how much time I had wasted. 直到工作,才认识到我已蹉跎了几多岁月。 (五)表示"一?就?"的结构 as soon as, the moment, the minute, the instant, once, immediately, directly, instantly(从句中用一 般时态代替将来时态) As soon as I got home, it began to rain.

Tell him the news as soon as you see him. The moment I heard the voice, I knew my father is coming. The boy burst into tears immediately he saw his mother. hardly/scarcely?when, no sooner?than(hardly/scarcely 与 no sooner 引导的句子的谓语动词用过去完成时, 而 when 与 then 引导的句子的谓语动词用一般过去时)如果 hardly, scarcely 或 no sooner 置于句首,句子必须 用倒装结构。 I had hardly / scarcely got home when it began to rain. I had no sooner got home than it began to rain. sb.had hardly/scarcely done sth.when... =Hardly / Scarcely had sb.done sth.when... I had hardly /scarcely closed my eyes when someone knocked at the door. =Hardly / Scarcely had I closed my eyes when someone knocked at the door.我刚一闭上眼,就有人在 敲门了。 I had hardly /scarcely entered my room when the telephone rang. =Hardly /Scarcely had I entered my room when the telephone rang.我刚一走进房门,电话就响了。
