中级美国英语助动词 could
一.本课要点及示例:
在这一课里, 我们要学习助动词 could, c-o-u-l-d, could 和两个助动词短语would like to, w-o-u-l-d l-i-k-e t-o, would like to 跟 ought to, o-u-g-h-t t-o, ought to. 我们也要学习用连接词 because, b-e-c-a-u-s-e, because 作句子.
首先我还是请两位英文老师给你念一段对话,内容是说亨利跟他的同事南希聊天的情况. 我请英文老师先用自然速度念一遍, 请你注意听英文老师的发音和声调.
M: Hello, Nancy! Where were you yesterday?
F: I didn't come in because I was sick.
M: You still look a little sick. You ought to go back to bed.
F: I'm going home now.
M: Did you drive today?
F: No, I don't have a car.
M: I can take you home. Would you like a ride?
F: Yes, I'll appreciate it very much. Could you stop at the drugstore on the way? I need to buy some aspirin.
好, 现在我请英文老师再把刚才那段对话用慢速度念一遍, 请你注意听:
M: Hello, Nancy! Where were you yesterday?
F: I didn't come in because I was sick.
M: You still look a little sick. You ought to go back to bed.
F: I'm going home now.
M: Did you drive today?
F: No, I don't have a car.
M: I can take you home. Would you like a ride?
F: Yes, I'll appreciate it very much. Could you stop at the drugstore on the way? I need to buy some aspirin.
在刚才那段对话里, 有几个句子用了我们今天要学的语法, 也就是 could, would like to, ought to 跟 because 的用法, 现在我请英文老师把这几个句子念出来给你听.
F: I didn't come in because I was sick.
M: You ought to go back to bed.
M: Would you like a ride?
F: Could you stop at the drugstore on the way?
二.助动词Could
好了, 现在我们来作练习. 首先我们学习助动词 could 的用法. 这个字是 can, c-a-n, can 的过去式, 是用来表示过去有能力作一件事. 不过这个字还有另外一个用法, 就是可以用在问句里表示客气地提出请求. 比方有一句话: "我没有车, 你能开车送我吗?" 用英文可以这样说: I don't have a car. Could you give me a ride?
好, 现在我们来练习这种用法. 由老师念一些句子, 内容都是说南希病了, 她客 气地请人帮忙. 每个句子我们念两遍, 请你听一遍, 跟着重复一遍.
M: I don't feel well. Could you help me?
F: I don't feel well. Could you help me?
M: I am sick. Could you take me to a doctor?
F: I am sick. Could you take me to a doctor?
M: I don't have a car. Could you give me a ride?
F: I don't have a car. Could you give me a ride?
M: I need to buy some medicine. Could you stop at the drugstore on the way?
F: I need to buy some medicine. Could you stop at the drugstore on the way?
M: I need to take the medicine. Could you give me a glass of water?
F: I need to take the medicine. Could you give me a glass of water?
下面我们来作换字练习.由老师念一个句子,比方: "我能借你的字典吗?" Could I borrow your dictionary? 然后老师给你一个新词组, 比方: 用你的电话 use your telephone, 请你把新词组代换到原来的句子里. 每作完一句就请你听正确答案.
好, 现在我们开始.
M: Could I borrow your dictionary?
M: use your telephone
F: Could I use your telephone?
M: read your newspaper
F: Could I read your newspaper?
M: take you home
F: Could I take you home?
M: see you tomorrow
F: Could I see you tomorrow?
M: talk to you later
F: Could I talk to you later?
三.词组Would like to
现在我们来学另外一种客气话, 也就是 would like to. 这个词组就是 "要" want to, w-a-n-t t-o, want to 的意思, 不过比较客气.
下面我们要作一组练习. 由老师念两个句子, 第一个句子用 want to, 第二个句子用的是 would like to. 这两句话意思一样.
M: Nancy wants to see a doctor.
F: Nancy would like to see a doctor.
M: Henry wants to watch television.
F: Henry would like to watch television.
M: Kate wants to buy a sweater.
F: Kate would like to buy a sweater.
M: Susan wants to visit her cousins.
F: Susan would like to visit her cousins.
M: Peter wants to become a sport star.
F: Peter would like to become a sport star.
M: Mary wants to have a weekly allowance.
F: Mary would like to have a weekly allowance.
刚才我们学习了怎么用客气话 would like' to 作陈述句, 下面我们看一看怎么用这个词组作问句. 比方有一句话: "你要做一个打字员吗?" 英文可以这么说: Would you like to be a typist? 另外一句话: "你要做市政府工作人员吗?" 英文可以这么说: Would you like to be a city worker? 好, 现在我们来作换字练习. 老师先念一个句子, 接着老师念一个新词组, 请你把新词组代换进去. 作完之后, 请你注意听正确答案.
M: Would you like to be a typist?
M: be a city worker
F: Would you like to be a city worker?
M: sing in a concert
F: Would you like to sing in a concert?
M: live near the university
F: Would you like to live near the university?
M: sit next to the window
F: Would you like to sit next to the window?
M: take two suitcases to New York
F: Would you like to take two suitcases to New York?
下面我们换一个方式作练习. 老师用 would you like to 作一个问句, 比方: "你要作一个救火员吗?" Would you like to be a fire fighter? 然后你会听到老师说 Yes或是 No, 请你根据你所听到的回答问题. 如果是肯定的, 就用 would 回答, 是否定的就用would not, 也就是wouldn't 回答. 作了答案之后, 请你听正确答案.
M: Would you like to be a fire fighter?
M: Yes
F: Yes, I would like to be a fire fighter.
M: Would you like to buy this record?
M: No
F: No, I wouldn't like to buy this record.
M: Would you like to have a glass of milk?
M: No
F: No, I wouldn't like to have a glass of milk.
M: Would you like to live near the factory?
M: No
F: No, I wouldn't like to live near the factory.
M: Would you like to play football this Friday?
M: Yes
F: Yes, I would like to play football this Friday.
四.词组Ought to
下面我们来学一个新词组 ought to. 这个词组的意思等于我们以前学过的助动词 should, s-h-o-u-l-d, should, 意思就是劝人应该作某一件事.比方有一句话: "你应该在银行停一下", 英文可以这样说: You should stop at the bank. 也可以这样说: You ought to stop at the bank.
现在我们来作练习. 由老师先用 should 作一个句子,请学生用 ought to 代替. 请你在学生念句子的时候跟着重复. 现在我们开始:
M: Nancy should see a doctor.
F: Nancy ought to see a doctor.
M: Kate should stop at the bank.
F: Kate ought to stop at the bank.
M: Henry should get in shape again.
F: Henry ought to get in shape again.
M: Peter should take out the garbage.
F: Peter ought to take out the garbage.
M: Linda should save some of her weekly allowance.
F: Linda ought to save some of her weekly allowance.
M: Mary should clean up her room.
F: Mary ought to clean up her room.
五.连接词 Because
好了, 现在我们来学这一课要教的最后一个语法, 也就是连接词because "因为"的用法. 要是有人问你: "为什么人们给市政府工作呢?" Why do people work for city governments? 你可以这样回答: 因为市政府工作人员退休时候有不少退休金. Because city workers get a good pension when they retire.
下面这组练习, 是由老师根据这一课开头那段说到南希生病的对话提出几个问题, 请学生用 because 来回答问题. 请你注意听.
M: Why does Nancy have to go home?
F: She has to go home because she needs to rest.
M: Why should Nancy go back to bed?
F: She should go back to bed because she is sick.
M: Why does Nancy have to stop at the drugstore?
F: She has to stop because she wants to buy some aspirin.
M: Why doesn't Nancy drive to work?
F: She doesn't drive to work because she doesn't have a car.
下面这组练习是由老师提出一个问题. 接着他再念一个短句, 请你用 because跟这个短句来回答问题. 在你回答之后请你注意听正确答案. 好, 现在我们就开始:
M: Why do you study English?
M: It's useful.
F: I study English because it's useful.
M: Why is he listening to radio?
M: There is a good program.
F: He is listening to radio because there is a good program.
M: Why can't we play tennis now?
M: It's raining.
F: We can't because it's raining.
M: Why didn't she go to the party with us?
M: She had to work.
F: She didn't because she had to work.
六.听短文回答问题
今天要听的文章是说到亨利和南希都是市政府工作人员, 谈到了他们两个人工作的性质.
请你注意听:
Many Americans work for city governments. There are office workers, fire fighters, police officers and public school teachers. Most city workers might not earn a lot of money but when they retire they get a good pension. Henry and Nancy are employees of the city of Seattle. He is a fire fighter. He is on duty eight hours a day. During his shift he eats and sleeps at the firehouse because the fire fighters have to be ready to answer an alarm. Nancy is a typist in Henry's office. She works from 9 o'clock in the morning to 5 o'clock in the afternoon. She works five days a week, Monday through Friday. Her job is to type reports of fire.
等一下我们还会把刚才那段文章用慢速度再念一遍. 现在我们先把今天要测验的三个问题用慢速度念一遍给你听.
第一个问题是:
M: What are some of the city government jobs?
第二个问题是:
