第三十九课　时间从句，抽烟与戒烟

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?

F: Yes, he has kept on smoking ever since he was 15.

M: Has he considered quitting smoking since he got back from China?

F: Yes, he has considered quitting smoking since he got back from China.

M: Did he tell Jenny his plan when he saw her?

F: Yes, he told her his plan when he saw her.

M: Was he smoking while he was talking to Jenny?

F: Yes, he was smoking while he was talking to her.

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
