中级美国英语Lesson6:助动词could

第六课　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?
