第22课过去进行式when与while
第二十二课过去进行式when与while一.本课要点及示例在这一课里, 我们学习过去进行式句子, 并且要学习用when, w-h-e-n, when 跟 while, w-h-i-l-e, while, 作表明时间的短句.现在我们来听今天这一课的对话, 内容说到凯特告诉亨利她开车超速被交通警察罚钱的事情. 请你注意听两位英文老师的发音和语调.F: I got a traffic ticket this afternoon.M: Were you parking in the wrong place?F: No, I was driving too fast.M: How fast were you going?F: 55 in a 35 mile per hour zone.M: Why were you in such a hurry?F: I left school late and I was trying to get home before the rush hour.M: Did you make it?F: No, when the police officer was giving me the ticket, the rush hour started. It took me twice as long to get home.在刚才那段对话里有一个常用的词rush hour, r-u-s-h h-o-u-r, rush hour 这个词指的是上下班交通最拥挤的时刻. 现在我们再把整段对话听一遍. 这次老师念的比较慢, 请你注意听.F: I got a traffic ticket this afternoon.M: Were you parking in the wrong place?F: No, I was driving too fast.M: How fast were you going?F: 55 in a 35 mile per hour zone.M: Why were you in such a hurry?F: I left school late and I was trying to get home before the rush hour.M: Did you make it?F: No, when the police officer was giving me the ticket, the rush hour started. It took me twice as long to get home.现在我把刚才那段对话里的过去进行式句子挑出来, 请老师再念一遍给你听.M: Were you parking in the wrong place?F: I was driving too fast.M: How fast were you going?F: I was trying to get home before the rush hour.F: When the police officer was giving me the ticket, the rush hour started.二.过去进行式听了上面那些句子,你或许已经注意到过去进行时态就是把动词加上i-n-g, 比方"停车" park, p-a-r-k, park 变成parking, "去" go, g-o, go 变成going, 然后在这个动词前面斟酌情况用was, w-a-s, was 或是were, w-e-r-e , were.现在我们来作一组练习, 由老师念一过去式句子, 请学生把句子改成过去进行式, 这些句子都是从刚才那段对话里挑出来的. 下面就是一个例子:M: Did you park in the wrong place?F: Were you parking in the wrong place?好, 现在我们开始作练习. 学生作句子的时候请你也一起作.M: Did you park in the wrong place?F: Were you parking in the wrong place?M: I drove too fast.F: I was driving too fast.M: How fast did you go?F: How fast were you going?M: I tried to get home before the rush hour.F: I was trying to get home before the rush hour.M: The police officer gave me a traffic ticket.F: The police officer was giving me a traffic ticket.三.WHEN在英文里过去时态是用来表示在过去某个时间里发生的事情; 而过去进行时态是用来表示在过去的一个动作已经发生的时候另外一个动作正在进行中.这种句子只有在对话中才能够单独存在, 所以我们必须在刚才练习过的过去进行式句子后面分别加上一个用when, w-h-e-n, when 开头的短句来说明过去两个动作的先后程序. 比方"交通警察在写罚款单给我的时候,交通就开始拥挤起来了" 这句话应该这样说: The rush hour started when the police officer was giving me a traffic ticket.现在我们来作一组练习, 把刚才学过的句子加上时间短句. 练习的作法是先由老师念一个有时间短句的过去进行式句子,然后你会听到一个简短的答覆, 请你根据你所听到的来回答问题. 首先我们举一个例子:M: How fast were you going when the police officer stopped you?F: 55 miles per hourF: I was going 55 miles per hour when the police officer stopped me.好, 现在我们开始作练习, 每作完一句就请你听正确答案.M: Were you parking in the wrong place when you got a traffic ticket?F: NoF: No, I wasn't parking in the wrong place when I got a traffic ticket.M: Were you driving too fast when you got a traffic ticket?F: YesF: Yes, I was driving too fast when I got a traffic ticket.M: How fast were you going when the police officer stopped you?F: 55 miles per hourF: I was driving 55 miles per hour when the police officer stopped me.M: Were you trying to get home before the rush hour when the police officer stopped you?F: YesF: Yes, I was trying to get home before the rush hour when the police officer stopped me.M: Was the police officer giving you a ticket when the rush hour started?F: YesF: Yes, the police officer was giving me a ticket when the rush hour started.下面我们用代换方式作另外一组练习. 在这组练习里用when 开头的短句包含的是过去进行时态动词, 比方亨利问凯特: "在你超速的时候你知道时速限制是多少吗?" Did you know the speed limit when you were speeding? 这个练习谈的都是亨利问凯特关于她开车超速的时候的事情. 在这组练习里, 你可以学到跟交通有关系的几个词, 比方"时速限制" speed limit, s-p-e-e-d l-i-m-i-t, speed limit, "规则" regulation, r-e-g-u-l-a-t-i-o-n, regulation, "交通标志" traffic sign, t-r-a-f-f-i-c s-i-g-n, traffic sign, "交通信号灯" traffic light, t-r-a-f-f-i-c l-i-g-h-t, traffic light, "公路" highway,h-i-g-h-w-a-y, highway 等等. 现在我们开始作练习.M: Did you know the speed limit when you were speeding?M: did you know the regulationF: Did you know the regulation when you were speeding?M: did you see the police carF: Did you see the police car when you were speeding?M: did you see the traffic signF: Did you see the traffic sign when you were speeding?M: did you see the traffic lightF: Did you see the traffic light when you were speeding?M: what was the speed limitF: What was the speed limit when you were speeding?M: how was the trafficF: How was the traffic when you were speeding?M: were you on the highwayF: Were you on the highway when you were speeding?M: were you in a hurryF: Were you in a hurry when you were speeding?四.WHILE现在我们来学习用while, w-h-i-l-e, while 作表明时间的过去进行语态短句. 这个字跟我们学过的when 意思相同,但是在用法上有一些区别. while 只能跟进行语态一起用, 而when 不受这个限制. 一般说来过去的两个动作同时都在进行的时候比较常用while.下面我们来作一组练习, 内容还是谈到亨利问凯特有关她被交通警察拦下来的事情. 现在请你根据亨利问的问题作肯定的答覆.每作完一句就请你听正确的答案.M: Were you talking to the police officer while he was writing the ticket?F: Yes, I was talking to him while he was writing the ticket.M: Were you looking at him while he was writing the ticket?F: Yes, I was looking at him while he was writing the ticket.M: Were you listening to the radio while you were waiting in your car?F: Yes, I was listening to the radio while I was waiting in my car.M: Were you smoking while you were waiting in your car?F: Yes, I was smoking while I was waiting in my car.M: Were you thinking while you were smoking?F: Yes, I was thinking while I was smoking.下面我们来作另外一组练习, 内容是说凯特向亨利说明她开车的时候并没有在吃东西或是在打电话等等. 练习的作法是凯特先念一个句子, 接着你会听到亨利说出一个动作, 比方"打电话" making a telephone call 或是"作白日梦" daydreaming 等等. 请你用亨利说的字或是词来代换原来句子里第一个动词.每作完一句就请你听正确答案.F: I wasn't eating while I was driving.M: drinkingF: I wasn't drinking while I was driving.M: sleepingF: I wasn't sleeping while I was driving.M: making a telephone callF: I wasn't making a telephone call while I was driving.M: daydreamingF: I wasn't daydreaming while I was driving.M: singingF: I wasn't singing while I was driving.下面一组练习是由老师念出两个过去式句子, 请学生把句子改成过去进行时态并且用while 把两个句子合并成一个句子. 首先举个例子.M: Henry watched television at home. The police officer gave Kate a ticket.F: Henry was watching television while the police officer was giving Kate a ticket.这组练习的内容是说当警察把罚款单给凯特的时候,别人都在作什么. 现在请你注意听老师念句子, 并且在学生作句子的时候也一起作.M: Henry watched television at home. The police officer gave Kate a ticket.F: Henry was watching television at home while the police officer was giving Kate a ticket.M: Peter camped in a national park. Henry watched television at home.F: Peter was camping in a national park while Henry was watching television at home.M: Mary hiked in a forest.Peter camped in a national park.F: Mary was hiking in a forest while Peter was camping in a national park.M: Linda looked at Peter's graduation pictures. Mary hiked in a forest.F: Linda was looking at Peter's graduation pictures while Mary was hiking in a forest.M: Jenny studied in her dormitory. Linda looked at Peter's graduation pictures.F: Jenny was studying in her dormitory while Linda was looking at Peter's graduation pictures.M: The police officer gave Kate a ticket. Jenny studied in her dormitory.F: The police officer was giving Kate a ticket while Jenny was studying in her dormitory.五.听短文回答问题首先我们来听一篇文章, 内容是说在美国街道和公路上开车有什么限制,比方要是有人开车超速, 警察就会写罚款单给他; 要是有人一连拿了好几张罚款单就可能暂时不准开车等等.现在请你注意听.Many regulations govern drivers on American streets and highways. The most common ones are the speed limits. The speed limit regulates how fast a car may go.On streets in the city, the speed limit is usually 25 or 35 miles per hour. On the highways between cities, the speed limit is usually 55 miles per hour. When people drive faster than the speed limit, a policeman can stop them. The policeman gives them pieces of paper which people call traffic tickets. Traffic tickets tell the drivers how much money they must pay. When drivers receive too many tickets, they probably cannot drive for a while.The rush hour is when people are going to work or going home from work. At rush hour there are many cars on the streets and traffic moves very slowly. Nearly all American cities have rush hours. Drivers do not get tickets very often for speeding during the rush hours because they cannot drive fast.刚才那篇文章你听懂了吗? 如果没全部听懂, 不要紧, 等一会儿我请英文老师再念一遍给你听. 现在我们先来听今天测验的问题.第一个问题是:M: What are the speed limits on American streets and highways?第二个问题是:M: What will happen when people drive faster than the speed limit?第三个问题是:M: How is the traffic during the rush hour?现在我请英文老师用慢速度再把整篇文章念一遍.Many regulations govern drivers on American streets and highways. The most common ones are the speed limits. The speed limit regulates how fast a car may go.On streets in the city, the speed limit is usually 25 or 35 miles per hour. On the highways between cities, the speed limit is usually 55 miles per hour. When people drive faster than the speed limit, a policeman can stop them.

At rush hour there are many cars on the streets and traffic moves very slowly. Nearly all American cities have rush hours.

On the highways, the speed limit is usually 55 miles per hour.第二个问题是:M: What will happen when people drive faster than the speed limit?F: A policeman can stop them and give them tickets.第三个问题是:M: How is the traffic during the rush hour?F: The traffic is usually very slow during the rush hour.。

英语人教版八年级下册过去进行时态中when和while 的选择
英语八年级下册人教版过去进行时态中连词when 和while 的选择教学设计阿左旗九中樊洁华教学背景：过去进行时态中，引导时间状语从句的连词“when”和“while”的选择是学生掌握的难点，也是教学重点。
通过微课的形式，集中讲解用法，为学生解惑。
教学目标:1.学生能够在过去进行时态中正确使用连词“when”和“while”。
2.学生能够区分终止性动词和延续性动词。
教学方法：讲解和练习。
教学过程：一．导入选择when 和while的三个原则。
二．讲解1.when意为“在……时刻或时期”，它可兼指“时间点”与“时间段”，所引导的从句的动词既可以是终止性动词，也可是持续性动词。
如：When I got home, he was having supper.我到家时，他正在吃饭。

过去进行时when和while
过去进行时的讲与练一、含义：(1)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。
(2) 过去进行时表示感情色彩与现在进行时相似，过去进行时也可表示满意、称赞、惊讶、厌恶等感情色彩，也通常与always，forever等副词连用。
e.g：They were always quarrelling. 他们老是吵架。
二、过去进行时的构成和用法：肯定形式：主语+was/were+doing否定形式：主语+was not (wasn't)/were not (weren't)+doing疑问形式：Was/Were+主语+doing。
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 和while 引导的时间状语从句。
三、when/while引导的时间状语从句①由when/while 引导的时间状语从句。
常用句型：a. 主句（主语 + was/were + doing … when + 一般过去时的句子）；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。
We were talking when the teacher came in.=While we were talking, the teacher came in.b. 主句（主语 + was/were + doing … while +主语 + was/were + doing …）；主句与从句的动作都是延续性动词或同时发生的，两句都用过去进行时的时候，多用while引导★★★注意：when和while的区别：都意为“当……时候”，when引导的句子谓语动词用短暂性动词或延续性动词都行；但while引导的句子谓语动词只能用延续性动词，不能用短暂性动词。
