VOA中级美国英语

一.本课要点及示例

在这一课里我们要复习现在完成式, 并且要学习两个时常跟现在完成式句子
一起用的连词, 一个是 since, s-i-n-c-e, since, 一个是 for, f-o-r, for.
现在我们还是按照惯例, 先请英文老师念一段会话,请你听的时候特别注意两
位英文老师的发音和语调.
M: Where have you been, Kate?
F: I've been at the garage for the last two hours.
M: What happened? Did you have an accident?
F: No, nothing happened. But we haven't had the car checked since February. It's needed
an oil change for a long time.
M: I know. Have you gotten the car back?
F: No. They've worked on it since four thirty, but they haven't finished it yet.
M: Well, when can we get it back?
F: I'll pick it up on Friday.
M: That's good. Then, we'll have it for the weekend.
现在我们再来听英文老师用慢速度把刚才亨利和凯特的对话念一遍.

下面这组练习的内容是说亨利从早上到现在已经作了什么事, 比方他已经到
过办公室, 已经写了一份报告, 已经见到了办公室打字员南希等等. 你先跟着
老师重复一个句子, 然后老师会提出一个新的词组, 请你把词组里的动词改成
过去分词, 代换到原来的句子里. 每作完一句老师会念出正确答案, 你自己作
个比较, 看你作对了没有. 现在开始.

下面一组练习是说凯特到修车厂买汽油, 顺便请人换机油的事情. 老师用慢速

三.I've 和 She's

以前我们练习过把 have not 简缩为 haven't, 把 has not 简缩为 hasn't. 下面我
们来练习怎么样把代名词跟 have 或是 has 连起来说. 比方 I have 说成 I've,
they have 说成 they've, she has 说成 she's 等等. 现在我们来作两组练习, 内
容都是亨利和凯特吃过晚饭之后话家常.
第一组练习是亨利问凯特是否已经作了某些事情, 凯特用 I've 作肯定的答覆.
请你注意听亨利问问题, 并且跟凯特一起回答问题.
M: Have you taken the car to the garage yet?
F: Yes, I've taken it to the garage.
M: Have you been to the new supermarket yet?

下面凯特问亨利一些有关亨利的同事南希的问题, 比方南希是否已经搬到郊
区, 是否已经决定结婚, 是否谈起到纽约渡蜜月的事情. 亨利用 she's 作肯定
的答覆. 请你注意听, 并且跟亨利一起回答.

F: Has Nancy planned to come over for dinner next Saturday?
M: Yes, she's planned to come over.

四.SINCE 和 FOR

刚才我们复习了现在完成式,同时也学了一些新词,现在我们要学习两个连词,
也就是 since 跟 for 的用法. 这个两个字常常跟现在完成式句子一起用. since
表示 "自从一个特定的时间开始", for 表示 "时间持续了多久".
现在我们来听英文老师念一些句子, 比较这两个连词的用法.
M: Henry and Kate have been married since 1962.
F: They have been married for a long time.
M: Henry and Kate have lived in Seattle since 1965.
F: They have lived in Seattle for a long time.
M: Henry has worked as a fireman since 1970.
F: He has worked as a fireman for many years.
下面这组练习是由老师问你一个问题, 然后, 他提出一个特定的时间请你用
since 跟这个特定的时间回答问题. 这些问题都是跟亨利作救火员有关系的.
每作完一句就请你听正确答案.
M: Has Henry wanted to be a fireman?
M: He was a child.
F: Henry has wanted to be a fireman since he was a child.
M: Has Henry worked as a fireman for a long time?
M: 1970
F: Henry has worked as a fireman since 1970.
M: Has Henry ever worked for the city government?
M: He got married.
F: Henry has worked for the city government since he got married.
M: Has Henry been very busy with his job?
M: last month
F: Henry has been very busy with his job since last month.
在下面一组练习里老师问学生一些有关凯特当教员的问题, 每问一句, 老师就
提出一个指明时间长短的词组, 请学生用 for 跟这个词组来回答问题. 请你在
学生作练习的时候也一起作.
M: How long has Kate been a teacher?
M: a long time
F: She's been a teacher for a long time.
M: How long has Kate taught in elementary school?
M: many years

下面一个练习是由老师给你念一个现在完成式否定句, 接着老师提出一个表
明时间的词组, 请你把这个词组用进原来的句子里. 注意凡是指明特定的时间
你就必须用 since, 凡是说明时间长短的词组, 你就必须用 for. 每作完一句就
请你听老师念正确答案. 看你作对了没有.

刚才那个练习你都作对了吗? 现在我们来作今天的听力测验.今天老师要念的
文章是说汽车在美国变得很普遍, 人们以汽车为主要交通工具, 上班, 上街, 去
旅行都要靠汽车.
现在请你注意听, 等一会儿老师会根据这段文章问你几个问题.
Perhaps more than any other people, Americans have come to depend on their cars.
The family car has been a common thing since the early 20th century, and it has changed
American life. Many people have moved outside of the large cities to the suburbs.
Some Americans spend two hours a day or more in their cars going to work and home
again. Cars have become the means of transportation for most Americans going
shopping, and even going on vacations.
Americans used to like big cars, and gasoline used to be very inexpensive. Recently,
however, the cost of gasoline has increased, smaller cars have become more common.
Also foreign cars have become very common. Americans have bought large numbers of
Japanese and German cars. They have bought cars from several other countries as well.
刚才那段文章要是你没有全懂, 没有关系, 等一会儿我请英文老师再给你念
一遍. 现在我们先来听今天测验的三个问题.
第一个问题是:
