Warming up、Pre-reading、Reading、Comprehending优质课教案

Unit 4 Learning efficiently Most students want to communicate better in English.If this is one of your goals，it is important to study a balance of the four major skills.Listening，Speaking，Reading and Writing are the main (macro) skills you need to communicate in any language.Being very good at only one of these skills will not help you to communicate.It helps to think of these communicative skills in two groups. First you have input.Next you have output.First you listen to someone ask you a question.Second you speak and give them your answer.First you read a letter from someone.After that you write back to them.Input and output don’t necessarily go in a specific order.Sometimes you speak first and then you listen.Sometimes you write about something you hear.During communication，the person you are communicating with uses one of the opposite skills. Some students want to know which skill is the most important.Since all of the skills rely on each other，they are all important.However，to communicate we do use some skills more often than others.For example，about 40% of the time that we spend communicating we are simply listening.We speak for about 35% of the time.Approximately 16% of communication comes from reading，and about 9% from writing.These statistics are for an average communicator in English.Depending on someone’s job or situation，these numbers may vary. Each of these main skills have micro skills within them.For example，pronunciation is a type of speaking skill that must be practiced in order to improve communication.Spelling is a skill that makes understanding the written word easier.Grammar and vocabulary are other micro skills.Micro doesn’t mean they are unimportant.

这也是为什么本书许多阅读课文前有预读活动的原因。

This is why...那就是……的原因，why后面接表示结果的句子，why引导表语从句，表示由上文的原因而导致的结果。

Mary broke the school rules；that was why she was punished by the headmaster. 玛丽破坏了学校的规章制度；那就是她为什么受到了校长惩罚的原因。

He was ill；that was why he was late for class. 他病了；那就是他上课迟到的原因。

“That/This is why＋从句”与“That/This is because＋从句”的区别：

(1)如果用来说明前面情况所产生的结果，就用“That/This is why＋从句”，相当于连词so的作用。

(2)如果用来说明前面情况的原因，就用“That/This is because＋从句”。

—Why hasn’t Jane been speaking to me for days? 珍这些日子为什么不和我说话？

—It was because you spoke ill of her behind her back. 那是因为你在背后说了她的坏话。

It was raining heavily at that time.That was why we got there so late.那时天正下着大雨，那就是为什么我们那么迟才到达那里的原因。

温馨提示：the reason (why...) is that...表示“(……)的理由是……”，that引导表语从句，一般不能省略，而且也不用because或why代替。

[即境活用15] (1)I don’t buy the dress.That’s ________ it didn’t suit me. A．because C．as B．for which D．why 解析：选A 从句“不适合我”是前面结果的理由，因此用because引导表语从句。

(2)I had neither a raincoat nor an umbrellA．________ I got wet through. A．It’s the reason C．That’s because B．That’s why D．It’s how 解析：选B 前面叙述的是理由，从句“我浑身都湿了”是结果，故用B。

(2)suppose vt.推想，猜想vi.料想

(1)suppose＋that从句

猜想，认为……

to dosuppose＋宾语＋宾补形容词介词短语

猜想，认为

(2)suppose that­clause中注意否定转移，即主语＋don’t suppose that­clause

(3)省略答语

I suppose so.我认为是这样。

I don’t suppose so.＝I suppose not.我不这么认为。

We supposed him (to be) dead.我们猜想他是死了。

I don’t suppose he will come here. 我想他不会到这儿来。

(3)be supposed to do应该做

C．It’s all up to you

B．I don’t mind D．That’s your decision

解析：选C 句意为：“我们现在就去艺术展览会怎么样？”“由你来决定吧。”本题考查交际用语。It’s all up to sb.意思是“一切由……来决定”。

2．Being poor，the couple have to have their baby________. A．adapt C．adopted B．adopt D．adept 解析：选C 句意为：因为贫穷，这对夫妇不得不把孩子给别人收养。have...done使17

某人……；adopt收养。

3．I looked at him in________.I didn’t expect to see him again in such an occasion. A．public C．secret B．person D．surprise 解析：选D in public表示“公开地，当众地”；in person表示“亲自”；in secret表示“秘密地”；in surprise表示“吃惊地”。从句子语境看，在这样一种场合下看到他，实在令我吃惊不已，我没有料到，所以只有in surprise符合题意。

4．—I drove to Zhuhai for the air show last week. —Is that________you had a few days off? A．why C．what B．when D．where 解析：选A 由于开车去珠海，故请假，why后从句表结果。

6．There is a________bus service into the centre of town. A．often C．frequently B．frequent D．frequency 解析：选B frequent用作形容词，可作定语或表语，而often只用作副词。

7．It is surprising that the drug doesn’t have any________on his illness. A．effective C．effect B．efficient D．efficiency 解析：选C have effect on对……有效。而efficiency效能，效率，不符合句意。

Ⅵ.阅读理解

When he was young，Hitchcock，the world­famous film director，once traveled in the mountainous areas of Scotland and got lost.At last he saw a light in the distance and struggled along tiredly toward it. There was a cottage.Hitchcock knocked at the door and when it opened，he told the owner of the situation he was in，hoping to stay overnight in the house.But the owner said，“This is not an inn.Why should I let you stay overnight？”

Calmly，the visitor smiled，“I’ll prove it’s an inn with only three questions.”

The owner didn’t believe him，“If you can persuade me with your questions and I’m contented，I’ll let you stay free of charge.”

The first question Hitchcock put to him was：“Who had lived here before you moved in？”

The owner answered immediately，“My father.”

The second question was：“Then who was it that lived here before your father？”

The owner’s reply came fast as the first：“Of course it was my grandpA．”

Hitchcock continued to ask，“Who will be the owner of the house when you unfortunately pass_away？”

The owner said，“My son！”

At this moment the visitor smiled again，“That’s it.You stay here temporarily.Like me，you are also a passer­by.”

Thus Hitchcock finally persuaded the owner of the house and was permitted to stay.He enjoyed a good sleep there. 1．Why did Hitchcock have to ask for a night stay? A．He lost his way. B．He was too tired to go any further. C．It was too late to go on. D．He liked the cottage there. 解析：选A 细节理解题。第一段的第一句“...once traveled in the mountainous areas of Scotland and got lost”。

2．The author mentioned the writer’s father，grandfather and son in order to ________. A．prove the cottage was actually an inn 19

B．show they were similar to him C．tell the owner that the cottage must be an inn D．to prove they were friendly to him 解析：选A 细节判断题。根据第二、三段两人的对话可得出答案。

3．The underlined phrase “pass away” probably has the same meaning as ________.

A．go by C．die B．pass by D．be lost 解析：选C 词义猜测题。由下句儿子会住在这里可知pass away 指的是去世。

4．What did Hitchcock use to persuade the owner of the cottage to let him stay for the night? A．Good manners. C．Questions. B．Wisdom. D．Careful observation. 解析：选B 推理判断题。由故事内容可知Hitchcock当然是用自己的智慧了。
