时间状语从句教案新部编本 樊秀秀

教师学科教案[ 20 – 20 学年度第__学期] 任教学科:_____________ 任教年级:_____________ 任教老师:_____________ xx市实验学校

The Adverbial Clause of Time 樊秀秀 Learning aims: (教学目标) (注:教学目标以“为什么学,学什么,如何学”的顺序呈现) Emotion and values:(情感态度价值观) (注:此处以高考中时间状语从句的考频为例让学生知道时间状语从句的重要性)名词性从句、状语从句以及定语从句这三大从句是高中最重要的语法点。对于从句的考察贯穿高考英语试卷的始终,从第一个单项听力,到最后的写作。三者重要性不分伯仲。但正如大家知道的,“三大”之一的状语从句,种类繁多。时间、地点、原因、结果、条件、让步、目的、比较、方式9种。 这9种之中,对于高考来说,重要性的区别是很大的。考频为证,以2006-2010年5年全国高考18个省市的19套卷子的单项选择题为例,涉及到状语从句的题目共有93道,其中时间状语从句考到了24题。由此可见, 时间状语从句为重中之重。 Knowledge and skills (知识与技能) 1. 掌握并灵活应用when, while, as 的基本用法及区别; 2. 学习并掌握when, while 的特殊用法; 3. 掌握since, before 主从句的时态; 4. 区分since, before 常用句型。 Process and method(过程与方法) 1.Students’ presentation (学生展示) (通过学生展示学习when, while, as, since, before这些连词的用法) 2.Discussion and the teacher’s explanation (讨论与教师讲解) (通过讨论和老师讲解学习难点before与since的句型) 3.Individual work, group work (个人及小组活动) (通过个人与小组活动解决练习题) Important and difficult points(重点及难点) 1.When与while的特殊用法。 2.Before与since的时态及常用句型。 Teaching aids(教学手段) Multimedia(多媒体)chalk and blackboard(黑板) slide (幻灯片) Question presentation (问题呈现) 1.When while as的区别及when, while的特殊用法。( Group 1, 3, 8, 10 ) 2.since的用法及重要句型。( Group 2, 8, 11 ) 3.before的主从句时态及常用句型。( Group 5, 9, 10, 11 ) 评价问题:(8,10,11组在问题的预习及总结上做的最好,点出8组合作意识很强,但重点不突出) Teaching procedures(教学过程) Step I Lead-in(导入)(呈现教学目标的形式导入) Step II Question presentation(问题呈现) Step III The problems(解决问题) 1.时间状语从句的连接词(叫大家抢答,看大家是否足够熟悉) when whenever as while before after until (till) since as soon as

初中英语时间状语从句讲解及练习

语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同,可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样,状语从句的位置比较灵活。既可置于主句之前(通常用逗号与主句隔开),也课置于主句之后(不需要用逗号与主句隔开),有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生,这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续,具有at the same time的意思 他继续往下谈的时候,越来越兴奋。 as还可以表示一边??一边??,强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来,天气暖和起来。 ② when 强调动作点的特定时间,具有at the time that 的意思 当老师走进来的时候,我们都站起来了。 ③ while 表示较长的期间,具有during the time that 的意思 当我在这的时候,我很安全。 2.主句发生在从句之前,这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”,在否定句中意为“直到 --- 才”。从句既可置于主句前,也可置 于主句之后。 回家之前我必须干完所有的活。

When引导的定语从句与时间状语从句的区分

一、从句是如何出题的? 1. 时态 2. 考连接词 3. 考语言顺序 二、学好从句的两个基本条件 1. 时态 2. 从句的三个必须:①必须是句子;②必须有连接词;③必须是陈述句 三、状语从句、宾语从句、定语从句重点 1.如何判断何种从句 2. 从句的时态 3. 从句的连接词与扩展 4. 经典单选、从句与选词、长句子分析 四、如何判断三种从句 1. 状语从句无先行词 2. 宾语(表语)从句无先行词有动词或词组 3. 定语从句先行词多为名词或代词 一、When引导的定语从句与时间状语从句的区分 1. when的译法不同。在时间状语中,when 翻译成“当……的时候” I want to be a teacher when I grow up. 当我长大的时候,我要做一名老师。在定语从句中,when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。 2. 在时间状语中,when从句前面或后面是句子;定语从句中,when 从句不能位于句首,且通常when前为表示时间的名词day、year等。 3. when在从句的作用不同。在时间状语从句中,when是连词,只起连接主句和从句的作用,不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语,做主句的时间状语。 在定语从句中,when是关系副词,在从句中代替先行词做从句的时间状语,修饰从句的谓语。 例1 I will always remember the days when I lived with my

grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评:例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”,其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时,总是会想起在乡下的那些日子”,其中when 引导的从句并不修饰前面的名词the country,因此可判定为时间状语从句。 例1中的when可用in which替代,即从句可改为...in which I lived with my grandparents in the country. 例2中从句前有名词,但根据句意可 知并不是从句所修饰的对象,也不能用“介词+ which”来替代。 二、判断关系代词与关系副词 方法一:用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如: This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you. 我永远不会忘记与你共事的日子。 判断改错: 1. This is the mountain village where I visited last year. 2. I will never forget the days when I spent in the countryside. 3. This is the mountain village (which)I visited last year.

语法讲解 时间状语从句的用法解析及练习

语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语,其位置较灵活,可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号,放在句末时状语从句前面往往不用逗号)。根据状语从句的含义,状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结,希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since,whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同,要注意把握不同的时间状语从句的引导词所表示的不同时间关系,以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析: (1) when引导时间状语从句时表示“当……的时候”,when既可以指时间段也可指时间点,从句中既可用延续性动词又可用非延续性动词,且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句:I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹,这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了,其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时,妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同,而从句的谓语又是be动词时,那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时,往往还可以用“when+分词”的形式替代该状语从句。例如:When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候,我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”,它强调主句的动作与从句的动作同时持续地进行,用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词,或者主句的动作发生在从句动作的进行过程中,主句中的谓语动词通常是非延续性动词,例如:Study while you study; play while you play. 该学习的时候就学习,该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时,一边……一边……”,侧重表示两个动作同时发生(包括一个主语同时进行两个动作),或者一种动作随着另一种动作的变化而变化。例如:He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

时间状语从句讲解和练习

时间状语从句 用句子表达一件事情或一个行为发生的时间,这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同,所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句: 1.when引导的从句:表示主句的动作和从句的动作同时发生,或从句的动作发生在主句动作之前。 例如:I was going out when a visitor came. (动词动作同时发生。)我正要出门,有客人来访。 I shall tell her the good news when she comes.她来时,我将告诉她这个好消息。 小试牛刀:I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get) 2.while 引导的从句:表示“当……过程中”,强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为,所以从句中要用持续性动词,并且持续性动词常用进行时态。 例如:Keep an eye on my little sister while I am away.我不在时,请照看一下我的小妹妹。 While we were watching TV, Jim came in. 我们看电视的时候,Jim进来了。 小试牛刀:It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music. 3.as引导的时间状语从句:表示“当……的时候;一边……一边……;随着……”,其从句的主语与主句的主语往往是同一人或物。 例如:She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working. I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。 小试牛刀: we walked, we talked. You will grow wiser you grow older. 4.before引导的从句:一般表示主句的动作发生在从句动作之前。 例如:I didn’t know any English before I came here. 我到这儿来之前,一点英语都不懂。 例如:I had written my report before my father came back. 小试牛刀:He bought the ticket he went to see the film. 5.after引导的从句:表示主句的动作发生在从句动作之后。 例如:After he locked the door, he left. 他锁上门后,就走了。 After he had finished his work, he played a game of chess with his friend. 他做完工作后,和朋友下了一盘棋。 小试牛刀:I will go out to play basketball with you. I finish my homework.(after) _______________________ _ He left the classroom he had finished his homework the other day. 6.since引导的从句:表示“自从……以来”,从句中的动词一般表示动作的起点,用过去时。主句中的动词表示动作延续的情况,一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态,可用一般现在时。 例如:Since he met this good friend, he has made great progress in his studies. 自从遇见了这个好朋友,他已在学习上取得了巨大的进步。 例如:It is twenty years since she joined the Party. 她入党二十年了。(主句中的动词表示的是状态,用现在时。) 小试牛刀:it is five years since we last time.(meet) Mr green has taught in that school since he (come) to China three years ago.

时间状语从句讲解与练习

时间状语从句讲解与练习

when, while 和as 引导时间状语从句的用法 一、when 的用法 如果只从现象来看,when 从句用的最多的是一般过去时,而主句的时态没有限制,根据具体情况而定。 1. When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 2. When she came into my room, I was just reading a book. 她走进我房间时,我正在看书。 3. Were you writing when the teacher came in? 老师进来的时候,你在写信吗? 4. Sorry, I was out when you called me. 对不起,你打电话来的时候我出去了。 5. He was on the point of leaving when someone knocked at the door. 他正要走,这时有人敲门。 6. I thought of it just when you opened your mouth. 就在你要说话的时候,我也想到了。 7. I had hardly[scarcely] closed my eyes when someone knocked at the door. 我刚一闭上眼,就有人在敲门了。

根据以上的例句,我们可以总结出一点:when 从句的A事件,相当于另一个事件B发生的时间点。也就是说,when 从句的重点不在动作本身发生的状态,而只是把它作为一个时间点,所以when 多数情况下用的是一般过去时,则不用正在进行时。因为如果用正在进行时,它表示的就是一段时间而不是一个时间点了。根据这一点,有的文章补充说:when 从句的动词大多是瞬时动词。 实际上,when 从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时间参照点。 1. When I got to the airport, the guests had left. 当我赶到飞机场时,客人们已经离开了。 2. When he had finished his homework, he took a short rest. 当他完成作业后,他休息了一会儿。 3. Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作,为何还想再找新的? 4. You shall borrow the book when I have

时间状语从句讲解讲课教案

(adverbial clause of time) 概念:在复合句中,由时间连接词引导的状语从句叫做时间状语从句。(在复合句中,要注意主句和从句的时态大多都要保持一致。) 1.由when, while, as,after,before,since,untill,引导的时间状语从句。例如: When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候,你就是在开始知道一些事物了。 When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候,它在生长,它感到压抑,它蓄存着这么一种爆炸性力量,一旦冒出,它就会炸破一切! Strike while the iron is hot. 趁热打铁。 You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候,你就能感觉到空气在流动。 Our headmaster laughed as she spoke.我们的校长边谈边笑。 主要时态:主过从过;主将从现;主句为一般现在时,从句不受影响。 编辑本段when, while和as的区别 when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。并且when 有时表示“就在那时”。例如: When she came in, I stopped eating.她进来时,我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当我住在农村时,我常常为他担水。(延续性的动词) We were about to leave when he came in.我们就要离开,就在那时他进来了。 While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。例如: While my wife was reading the newspaper, I was watching TV. (was reading 是延续性的动词,was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。(对比) As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生;as也可以强调“一先一后。例如: We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”)As we was going out, it began to snow.当我们出门时,开始下雪了。(as 强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间) 2.由before和after引导的时间状语从句。注意before引导的从句不再用否定式的谓语,并且当before引导的从句位于主句之后,有时译成“就,才”。还要注意主句和从句之间的时间关系。当主句用将来时,从句总是用现在时;如果before 引导的主句谓语用的是过去完成时,则从句动词多用一般过去时,这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和

过去进行时、when和while引导时 间状语从句的区别

过去进行时过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作,常和表过去的时间状语连用,如: 1. I was doing my homework at this time yesterday. 昨天的这个时候我正在做作业。 2. They were waiting for you yesterday. 他们昨天一直在等你。 3. He was cooking in the kitchen at 12 o'clock yesterday. 昨天12点,他正在厨房烧饭。 过去进行时的构成: 肯定形式:主语+was/were+V-ing 否定形式:主语+was not (wasn't)/were not (weren't)+V-ing 疑问形式:Was/Were+主语+V-ing。 基本用法: 1. 过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有,at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…),when sb. did sth.等时间状语从句,如: 1)What were you doing at 7p.m. yesterday? 昨天晚上七点你在干什么? 2)I first met Mary three years ago. She was working at a radio shop at the time. 我第一次遇到玛丽是在三年前,当时她在一家无线电商店工作。 3)I was cooking when she knocked at the door. 她敲门时我正在做饭。 2. when后通常用表示暂短性动词,while后通常用表示持续性动词,而while所引导的状语从句中,谓语动词常用进行时态,如: When the car exploded I was walking past it. = While I was walking past the car it exploded. 3. when用作并列连词时,主句常用进行时态,从句则用一般过去时,表示主句动作发生的过程中,另一个意想不到的动作发生了。如: I was walking in the street when someone called me. 我正在街上走时突然有人喊我。 4. when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。如:

When引导的三类从句

When引导的三类从句 When作为连词,可以引导名词从句、定语从句和时间状语从句。请看下面这段短文,其中就出现了when引导的这三类从句。 1. (a) Many students say that their time at university is when they can experience pure love. (b) This is a time when love is innocent when two people come together for love, rather than a house, car or a good job. There are no pressures from parents to get married as they are still young. (c)It is a time when they can choose who they love and how they love away from outside pressure. Even though the relationship may break up, it will bring sweet memories in later years. 很多学生都说,在大学期间才能经历真正纯真的爱情。在此期间,爱是单纯的,两个人走到一起完全是因为爱,而不是为了房子、车子或者好工作。由于还年轻,他们也不会迫于父母的压力而结婚。这一期间,他们可以不受外界的任何干扰而去选择自己爱的对象和爱的方式。即使最终两人分手了,这期间的爱情也会成为日后甜蜜的回忆。 上面的小短文中出现了四个when引导的从句,下面笔者逐一分析各句的结构与类型。首先来看a句: a.

英语时间状语从句讲解与练习 (一)when, while 和as 引导时间状语从句的用法 一、when 的用法 如果只从现象来看,when 从句用的最多的是大凡过去时,而主句的时态没有限制,根据具体情况而定。 1. When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 2. When she came into my room, I was just reading a book.她走进我房间时,我正在看书。 根据以上的例句,我们可以总结出一点:when 从句的A事件,相当于另一个事件B发生的时间点。也就是说,when 从句的重点不在动作本身发生的状态,而只是把它作为一个时间点,所以when 多数情况下用的是大凡过去时,则不用正在进行时。因为如果用正在进行时,它表示的就是一段时间而不是一个时间点了。根据这一点,有的文章补充说:when 从句的动词大多是瞬时动词。这种说法也可以参照。 实际上,when 从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时间参照点。例如: 1. When I got to the airport, the guests had left.当我赶到飞机场时,客人们已经离开了。 2. When he had finished his homework, he took a short rest. 当他完成作业后,他休息了一会儿。 3. Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作,为何还想再找新的? 二、while 的用法
