中级美国英语Lesson5:助动词should和must

凡是陈述句的主词是第三人称 "他" 的时候, 就应该用 has to. 下面我们要 练习这类句子. 老师先用 does, d-o-e-s, does 开头作问句, 请你用 has to 来 回答问题. 作完一句还是请你听正确答案.

M: Does he have to go to New York?

F: Yes, he has to go to New York.

M: Does he have to clean up his room?

F: Yes, he has to clean up his room.

M: Does she have to take the bus?

F: Yes, she has to take the bus.

M: Does she have to drop this course?

F: Yes, she has to drop this course.

have to 的否定式 don't have to 跟 has to 的否定式 doesn't have to 都可以 用来表示不一定非得作某件事, 而有其他选择. 在下面一组练习里, 我们 要多学学这类句子. 每个句子我们还是念两遍, 还是请你听一遍, 重复一

遍:

M: I don't have to buy records. I can listen to the radio.

F: I don't have to buy records. I can listen to the radio.

五.听短文回答问题

首先还是请你听一段文章, 内容是说彼得跟琳达兄妹两个人应该帮着作 些什么家事才能每星期拿零用钱.

现在请你注意听:

Every week Peter and Linda receive five dollars from their parents. This money is their weekly allowance. It is not a gift. Peter and Linda must work for the family to earn the money. Peter takes out the garbage and cleans the yard around the house. He should do it everyday, but sometimes he forgets. Linda helps her mother with the cooking. She also washes the dishes after dinner. Peter and Linda don't have to use their money for food. They use it for their entertainment. Sometimes they go to the movies. Sometimes they buy records. Each week they save some of their money to buy something more expensive.

刚才那段文章你听懂了多少? 文章里包含了今天教的语法, 你是不是注意 到了? 等一会儿我们会把整段文章再念一遍. 现在我们把今天测验的三个 问题先念一遍给你听.

第一个问题是:

M: What should Peter do to earn his weekly allowance?

第二个问题是:

M: Does Linda have to use her allowance for food?

下面是第三个问题:

M: How do Peter and Linda spend their money?

Every week Peter and Linda receive five dollars from their parents. This money is their weekly allowance. It is not a gift. Peter and Linda must work for the family to earn the money.
