Before ReadingDiscuss the questions. What do you often do to help your
parents at home?
2. Do you think kids should help out
with chores at home?家务活2aWhile reading: The Sunday Mail magazine invited parents to write about whether they think young people should do chores at home.
Skim the following letters.
Which one agrees?
Which one disagrees? SkimmingMs. Miller does.Mr. Smith does. 1st Reading2b 2nd ReadingWhile reading: According to Ms. Miller and Mr. Smith,
what are the pros and cons about kids doing chores?支持反对It teaches them to look after
themselves.It also helps them to understand
the idea of fairness.Doing chores helps to develop
children’s independence.
Housework is a waste of
children’s time.
When they get older, they will
have to do housework so there is
no need for them to do it now.Doing chores is not so difficult.
I do not mind doing them.
2cThe Letter from Ms. MillerWhile reading: 3rd ReadingWhat does Ms. Miller think about young children
doing chores at home? Why?2. What does she think kids should do ?She disagrees that young children should do chores
at home. She thinks housework is a waste of time. She thinks they should spend their time on
schoolwork in order to get good grades and get into
a good university.3. Why does she think there is no need for kids to do
chores now?Because she thinks when they get older, they will
have to do housework . The Letter from Ms. MillerDear Sir,
I do not understand why some parents make their kids help with housework and chores at home. Kids these days already have enough stress from school. They do not have time to study and do housework, too. Housework is a waste of their time. Could we just let them do their job as students? They should spend their time on schoolwork in order to get good grades and get into a good university. Also, when they get older, they will have to do housework so there is no need for them to do it now. It is the parents’ job to provide a clean and comfortable environment at home for their children. And anyway, I think doing chores is not so difficult. I do not mind doing them.
Ms. Miller While reading: 3rd ReadingWhat does Mr. Smith think about young children
doing chores at home? 2. Why does he think so?He thinks it is important for children to learn how to
do chores and help their parents with housework.
It is not enough to just get good grades at school. 3. What does he think doing chores can help kids?The Letter from Mr. SmithChildren these days depend on their parents too much. He thinks doing chores helps to develop children’s independence and teaches them how to look after
themselves. It also helps them to understand the idea of fairness.Dear Sir,
I think it is important for children to learn how to do chores and help
their parents with housework. It is not enough to just get good
grades at school. Children these days depend on their parents too
much. They are always asking, “Could you get this for me?” or
“Could you help me with that?” Doing chores helps to develop
children’s independence and teaches them how to look after
themselves. It also helps them to understand the idea of fairness.
Since they live in one house with their parents, they should know
that everyone should do their part in keeping it clean and tidy. Our
neighbors’ son got into a good college, but during his first year, he
had no idea how to take care of himself. As a result, he often fell ill
and his grades dropped. The earlier kids learn to be independent,
the better it is for their future.
Mr. Smith

One must do it the right way.The earlier you study hard,
the better grades you will get.2dAfter reading: Discuss the questions with a partner.1. Which letter do you agree with? Why?2. What would you say to the person who wrote the letter
you don’t agree with?2e Language points:It is the parents’ job to provide a clean and
comfortable environment at home for their
children.provide sth for sb 为某人提供某物 =provide sb with sth 为某人提供某物 (1)provide意为“提供；供应；供给”，表示供给所需物品以方便使用，其后常接名词或代词作宾语或
双宾语，并且常和介词with / for搭配使用。即：e.g. Mr. Smith provided food for us. e.g.史密斯先生为我们提供食物。 = Mr. Smith provided us with food. Language points: (2) It is one’s job (duty,..) to do something.
固定句型，表示“做某事是某人的工作（职责等）”e.g. 把东西给学生讲明白是每一位老师应做的是事情。 It’s every teacher’s job to explain things clearly
to the students. Language points: anyway [‘eniwei] adv. 论如何，不管怎样；总之位于句首时，其后往往有逗号将其与其他内容隔开。2. And anyway, I think doing chores is not
so difficult. 反正我觉得干家务也不太难。anyway在此句中的作用是追加评论，相当于
“反正；仍然；依然”
e.g.山姆没有得到那份工作，但他并没有闷闷不乐，
反正薪酬也不算高。Sam didn’t get the job, but he’s not unhappy
because it didn’t pay well anyway. Language points:3. The earlier kids learn to be independent,
the better it is for their future.
孩子们越早学会独立，对他们的未来就越好。 “the +比较级+…, the + 比较级+…”
是一个常用句型结构，表示“越…就越…”e.g. 他解释得越多，我们就理解得越透彻。The more he explained, the better we understood.Goodbye !新目标英语工作室—21世纪教育网名师工作室 新目标英语工作室作者系中学英语一级教师，长期从事英语教学和研究工作，有近20年一线教学的工作经验， 熟悉所任教教材信息和和该学科教改信息，愿意和广大英语教师和学生交流。本工作室将为21世纪教育网的广大师生贡献原创作品和整编作品，力争打造21世纪教育网金牌工作室。本工作室主要作品为新目标初中英语7年级至9年级的课件、教案、学案、单元测试卷、月考卷、期中试卷、期末试卷等相关教学资料。网址：http://www.21cnjy.com/book.php?mod=studio&op=detail&stid=13资料推荐课件23张PPT。UNIT 3Could you please clean your room?The Fifth PeriodSection B (3a-3b)Revision 用情态动词can, can’t, may, must, mustn’t,

1) 情态动词不能表示正在发生或已经发生的事情, 只表示期待或估计某事的发生。
2) 情态动词除ought 和have 外, 后面只能接不带to 的不定式。
3) 情态动词没有人称,数的变化,即情态动词第三人称单数不加-s。
4) 情态动词没有非谓语形式,即没有不定式、分词等形式。
情态动词用法小结 could与can的区别：
could与can都是情态动词,could是can的过去式。二者都可用于表示请求, 但是用法稍有不同。
can表示一般性的请求,语气随便，常用于熟人之间或长辈对晚辈, 上级对下级的场合。 e.g. Can you tell us if it snows in winter in Australia?
Sure.
请告诉我们, 澳大利亚冬天下雪吗? 当然可以。
1.提出委婉的请求在回答中不可用could。
--- Could I have the television on?
--- Yes, you can. / No, you can’t.
2. 在否定、疑问句中表示推测或怀疑用could 。。
He couldn’t be a bad man.
他不大可能是坏人。may和might
表示允许或请求;表示没有把握的推测; may 放在句首,表示祝愿。
May God bless you!
He might be at home.
注意: might 表示推测时,不表示时态。只是可能性比may小。have to和must
1) 两词都是 “必须”的意思, have to 表客观的需要, must 表说话人主观上的看法, 既主观上的必要。 My brother was very ill, so I had to call the doctor in the middle of the night.
我弟弟病得很厉害,我只得半夜里把医生请来。(客观上需要做这件事)
He said that they must work hard.
他说他们必须努力工作。(主观上要做这件事)2) have to有人称、数、时态的变化,而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。
He had to look after his sister yesterday.3) 在否定结构中:don’t have to 表示 “不必”, mustn’t 表示“禁止”。
You don’t have to tell him about it.
你不一定要把此事告诉他。
You mustn’t tell him about it. 你一定不要把这件事告诉他。情态动词的回答方式
问句 肯定回答 否定回答
Need you…? Yes, I must. No, I needn't
Must you…? /don't have to.
典型例题
1）-Could I borrow your dictionary?
-Yes, of course, you ____.
A. might B. will
C. can D. should 答案C. can. could表示委婉的语气,并不为时态。答语中of course,表示肯定的语气,允许某人做某事时,用can和may来表达,不能用could或might。
复习: will 与you连用,用来提出要求或下命令。
should与you 连用,用来提出劝告。

A. needn’t B. wouldn’t

- ___.
A. I don’t B. I won’t
C. I can’t D. I haven’t 答案B. I won’t. will既可当作情态动词,表请求、建议、也可作为实义动词表 “意愿、意志、决心”,本题表示决心,选B。Self check1 Make a list of chores using these verbs.1. do _________________________________
