一.本课要点及示例
   在这一课里,我们一方面复习用when, w-h-e-n, when,  before,   b-e-f-o-r-e,  before,
   since, s-i-n-c-e, since 等等介词开头, 用来表明时间的从句, 一方面复习以前学
   过的一些动词词组, 同时我们要学一学有关抽烟,戒烟的一些词汇.
   首先我们来听今天这一课的对话,内容是说鲍勃告诉珍妮他想戒烟. 请你注意
   听两位英文老师的发音和语调.
   M: Jenny, I'm going to stop smoking when I finish this pack of cigarettes.
   F:  Good for you, Bob, but why are you telling me?
   M: To help me stop. When I tell all my friends, then I won't dare to smoke in front of them.
   F:  Why do you want to quit? I thought you liked to smoke.
   M: I  do.  But  it's  getting  so  expensive.    And  now  that  I'm jogging, when I run, I can hardly
   breathe
   F:  I'll help you quit. Whenever you want a cigarette, call me and I'll take  your mind off it.
   M: Thanks, Jenny, I'll do it.
   F:  Bob, why don't you stop now? You don't have to smoke the rest of that pack.
   M: I just bought it. I don't want to waste my money. I'll call you tomorrow.
   下面老师用慢速度再把整段对话念一遍.
   M: Jenny, I'm going to stop smoking when I finish this pack of cigarettes.
   F:  Good for you, Bob, but why are you telling me?
   M: To help me stop. When I tell all my friends, then I won't dare to smoke in front of them.
   F:  Why do you want to quit? I thought you liked to smoke.
   M: I  do.  But  it's  getting  so  expensive.    And  now  that  I'm jogging, when I run, I can hardly
   breathe
   F:  I'll help you quit. Whenever you want a cigarette, call me and I'll take  your mind off it.
   M: Thanks, Jenny, I'll do it.
   F:  Bob, why don't you stop now? You don't have to smoke the rest of that pack.
   M: I just bought it. I don't want to waste my money. I'll call you tomorrow.
   现在我把对话里包含时间从句的句子挑出来, 请老师再念一遍给你听.
   M: I'm going to stop smoking when I finish this pack of cigarettes.
   M: When I tell all my friends, then I won't  dare to  smoke in   front of them.
   M: When I run, I can hardly breathe.
   F:  Whenever you want a cigarette call me.
二.表明时间从句的介词
   现在我们开始作练习.   第一组练习是说鲍勃什么时候抽烟, 练习的作法是老
   师念一个句子, 接着老师念一个词或是词组, 比方  "紧张" nervous,   "在指定
   地区"  in the designated area 等等,    学生就把他听到的词组代换到原来的句
   子里. 在学生作练习的时候请你也一起作.
   M: Bob smokes when he is studying for the exams.
   M: nervous
   F:  Bob smokes when he is nervous.
   M: in the designated area
   F:  Bob smokes when he is in the designated area.
   M: watching television
   F:  Bob smokes when he is watching television.
   下面一组练习是说鲍勃什么时候不抽烟,   比方在跑步的时候,  在禁烟地区的
   时候等等. 请你跟刚才一样作练习.
   M: Bob doesn't smoke when he is in a theatre.
   M: on a bus
   F:  Bob doesn't smoke when he is on a bus.
   M: jogging
   F:  Bob doesn't smoke when he is jogging.
   M: in a restricted area
   F:  Bob doesn't smoke when he is in a restricted area.
   下面我们作一组综合练习, 用许多不同介词作表明时间的从句, 同时我们也要
   复习一些跟动名词一起用的动词词组,  比方 take up,   keep on, give up 等等. 练
   习的内容也都跟鲍勃抽烟有关系. 请你注意听老师问问题, 并且根据问题作肯
   定的答覆.  每回答一句老师就会念正确答案给你听.
   M: Did Bob take up smoking after he went to high school?
   F:  Yes, he took up smoking after he went to high school.
   M: Has he kept on smoking ever since he was 15?

   M: Did he say that he would give up smoking when he finished his last pack of cigarettes?
   F: Yes, he said that he would give up smoking when he finished his last pack of cigarettes.
   下面我们再用同样方式作一组练习复习动词词组和表明时间的从句. 练习的
   内容是说鲍勃的父亲在得肺癌之前老是抽雪茄, 后来住院的时候戒了,   出院
   以后又改抽烟斗的事情. 请你根据问题作肯定的答覆.    回答之后请你听老师
   念正确答案.
   M: Did Bob's father use to smoke cigars before he got lung cancer?
   F:  Yes, he used to smoke cigars before he got lung cancer.
   M: Did he try to put it off when he was told to quit?
   F:  Yes, he tried to put it off when he was told to quit.
   M: Did he finally give up smoking cigars when he was in the hospital?
   F:  Yes, he finaliy gave up smoking cigars when he was in the hospital.
   M: Did he look forward to smoking whenever he saw other people smoke?
   F:  Yes, he looked forward to smoking whenever he saw other people smoke.
   M: Did he take up pipe smoking soon after he got out of the hospital?
   F:  Yes, he took up pipe smoking soon after he got out of the hospital.
   M: Did he keep on smoking until the day he died?
   F:  Yes, he kept on smoking until the day he died.
   下面我们再练习说明时间的从句. 练习的作法是老师用 when 提出一个 过去
   时态问题,比方"美国印地安人是什么时候开始种烟草的?"When did American
   Indians start growing tobacco?  然后老师说:  "哥伦布到美洲大陆以前" before
   Columbus came to America,  你就回答说: They started  growing tobacco before
   Columbus came to America.   老师也可能用 how long 提出现在完成时态问题,
   比方"烟草工业对美国经济具有重要性已经有多久了?"         How long has the
   tobacco industry been important for  America's economy? 然后老师说:"自从殖
   民地时代农民种植烟草外销以来"   ever  since   colonial farmers grew tobacco
   for export.你就回答说:It has been important  for America's economy ever since
   colonial  farmers grew tobacco  for export. 这组练习的内容跟美国烟草工业和
   美国人抽烟的情况有关系, 比方人们发现了某些疾病跟抽烟有关连以后,  香
   烟公司就开始卖有过滤嘴的香烟,     而政府也制定了一些有关抽烟的法规等
   等.   在这组练习里你可以学到一些有用的词汇, 比方 "降低" decline, "制定"
   institute,  "法规"   regulation,  "主要"   major, "目标"aim, "牌子"brand,"过滤嘴"
   filter, "疾病"ailment等等. 这组练习比较难, 请你在回答问题之前特别注意听,
   每回答一句, 老师就会念出正确答案给你听.

三.听短文回答问题
   今天我们要听的文章简单说到美国烟草工业的历史, 同时也谈到在美国人们
   因为注重健康而避免抽烟的趋势.   文章里许多词汇都是我们刚才练习过的.
   现在请你注意听.
   American   Indians  grew  and  smoked    tobacco   before   Columbus   came    to   America.
   The  tobacco  industry  has  been  large  and important for America's  economy ever since
   colonial farmers grew tobacco for export 300 years ago.     Even today tobacco is grown  in
   large quantities along America's  Eastern Coast.
   Since  the  1800's  the  most  common  form   of  smoking tobacco is in cigarettes.  Men  and
   women  of  all ages  smoke cigarettes  and  there   are  dozens  of  brands  sold  in  the U.S.
   Nearly  all cigarettes  now sold have filters.  Pipe smoking has some popularity and cigars
   are usually only  smoked  by older  men.
   Over the past fifteen years, many  people  have  stopped   smoking.  This movement away
   from  cigarettes  began  when  lung  cancer   and  other  ailments   were  linked  to   smoking.
   In the 1970's when taxes on cigarettes were greatly increased, cigarette smoking became
   much more expensive.  Since the late 1970's physical fitness has become a major  aim of
   millions of Americans.  These three factors have been the  major causes for many people
   to stop  smoking.
   Today in  the U.S.  cigarette  smoking  is   restricted  in  many  ways.  When smokers are in
   restaurants, on  trains and in public buildings, they may smoke   only  in designated  areas.
   When they are on public buses,  in theaters and in classrooms, they may not smoke at all.
   Cigarettes  are  not  advertised  on  television   or  radio. A  notice  is on every package  of
   cigarettes sold in America warning that smoking is dangerous to health. These regulations
   have reduced cigarette  smoking very much since they were instituted.   Smoking  is on the
   decline.
   现在老师先把今天测验的三个问题念一遍给你听.
