教材分析(Analysis of the teaching material)
1 地位与作用 (Status and function)
本单元的中心话题是“恐怖的自然”。围绕这一话题讨论了台风、火山等自然灾害发生时的现象及带来的影响。通过各个部分的学习，学生初步了解各种自然灾害及对人类带来的危害，从而增强保护环境和自我保护意识。
“热身”(Warming up) 通过四张图片引出自然现象：火山、台风和彗星及进行科学研究的仪器。通过师生问答形式，学生能描述自然现象并对台风、火山等自然灾害有初步了解。根据图式理论，将新学知识与学生已有的知识结合起来，能激活学生已有的图式，有利于新知识的掌握。通过这个阶段的语言训练为以下各部分的学习打下基础。
“听力”(Listening) 是一则天气预报。短文中出现了对各种天气的描述及美国各部分的气温情况。首先是细节题，根据听力短文指出美国哪些地区有雨及周二各部分的最高温。学生通过该部分练习来训练捕捉信息的能力。然后通过问题加深对短文的理解，最后达到能用英语做事的目的。
“口语”(Speaking)由两部分组成。第一部分是两人之间的对话，描述台风来时的情形和心理感受，为第二部分的配对练习打下基础。第二部分以六幅图片的内容话题，通过对话的形式来表述情感、焦虑和恐惧，为以后的写作打下基础。
“读前”（Pre-reading）部分先以两幅图片来激活学生已有的图式，对火山的形成有精确的理解。再通过三个问题，学生通过略读对以下的阅读材料有个总体的了解。
“阅读”(Reading)部分描述了“我的叔叔”--Pliny的死亡经过。Pliny不顾个人安危营救朋友，并在旅途中把自己的见闻记录下来，为后人留下宝贵的研究资料。从Pliny身上学生可以学习乐于助人、勇于奉献科学研究的精神。
“读后”(Post-reading)分三部分。第一部分通过brainstorming学生对火山及发生时的情形有更全面的了解。第二部分以寻找问题答案的形式，学生能加深对Pliny个人品质的认识。第三部分针对课文理解，通过填写表格培养学生的概括能力及描述事件的能力。
“语言学习”(Language study)分词汇和语法两部分。通过词汇练习来巩固本单元的生词，并且学生能正确使用现在分词和过去分词作表语。本单元的语法是“省略句”，主要包括省略主语、谓语、不定式及多种成分省略；先通过一些例子让学生自己探究省略的几种情况；再通过控制性练习掌握如何使用省略句；最后通过理解情景对话达到运用的目的，也就是能用英语办事。
“学习技能”(Integrating skills) 部分包括读、写两部分，读为写做铺垫。首先通过阅读学生了解故事情节：“南山”号轮船在驶回福建途中遭遇台风。更猛烈的大风即将袭来，整艘船危在旦夕…结尾部分给学生留下想象空间。写作部分是阅读的延续，学生通过想象描述“南山”号是如何脱险的。通过该部分教学不仅能提高学生的读写的语言技能能力，还能培养学生的创新思维能力。
“学习建议”(Tips) 给学生提供间接了解自然灾害的方法，从而培养学生自主学习能力。
“复习要点”(Checkpoint) 总结了本单元的语法重点---省略句。再通过一个问题帮助学生概括本单元的重要词汇。
各部分在练习册中都有相应的巩固练习。其中语言技能训练是课文的延伸和扩展，培养学生的说、读、写能力。在训练三种技能时增强学生探究能力和合作意识。

Teaching aids: a computer, a projector & a tape recorder
Step1 Revision
Questions: 1 What kinds of disasters does nature give us?
2 What kinds of disasters does man give us?
Step2 Pre-listening
Page 144,Listening. Look at the picture. Discuss Exercise1 with the students.
Step3 Listening
Play the tape for the students to do Exercises2-4. Then ask: What happened in the typhoon Linda talked about?
Step4 Lead-in

Model:
A: Have you been in a situation that frightens you?

Period 4 Integrating skills(Sb)
Teaching Aims:
1. Learn the text “typhoon” and master the detailed information in it.
2. Learn useful words and expressions
3. Write a passage about how the story will end.
Teaching important points:
1. To train Ss’ reading skills and writing skills
2. To master the usages of the new words and expression of this period.
Teaching difficult points:
1. To write a passage about terrible weather---- typhoon
2. To understand the difficult words, phrases and sentences
Teaching methods:
1. Fast reading and careful reading: to get the Ss to grasp the detailed information
2. Writing practice: to get the Ss to learn how to describe something terrible
3. Pair work or group work: to get the Ss to be active in class
Teaching Aids:
a computer, a projector, a tape recorder ( if the teacher wants )
Teaching procedures:
Step 1 Teaching Revision
k the homework
ll the story ( if the teacher likes )
ew the words and expression for talking about weather.
(This activity aims to review the words and motivate the Ss. In this way, the topic will be turned to typhoon.)
Step 2 Lead in
T: In the last few periods, we deal with a letter about volcano. It is a terrible nature disaster. This summer our hometown also experience a terrible disaster----- typhoon, one called Yunan. It caused great damage, isn’t it? Can you describe it? ( Ss: …. )
T: If it happens in USA, what do people call? (A hurricane )
In fact, a typhoon is the same thing as a hurricane except the place where they form. Before we deal with the detailed information, let’s watch a short video to experience the story wind again and here are two questions for you.
1. What does the hurricane bring in?
2. How long will it usually last?
(Ss watch the video and give the answers. If it is necessary, play it twice.)
Step 3 Pre-reading
T: We know typhoons can cause great damage or even deaths. In order to reduce the loss and protect ourselves, we have to learn more about it. Then what else do you know about the typhoon? Tell us what you know, please! First talk with your partner and then tell the whole class what you have discussed.
( pair work for two minutes and then one or two Ss report )
(This activity is to motivate the Ss to talk in English and cooperate well with each other.)
( Then the teacher introduce the background information )
T: Now, Let’s look at the diagram. We’ll know what is typhoon. Typhoon is a kind of tropical cyclone. It’s the atmospheric whirlpool formed on the warm tropical ocean and the area of low pressure. Winds are produced because the pressure of the air is different in different places. Air flows from a region of high pressure to a region of low pressure, causing a wind. The low pressure center is the eye of the storm. And tropical cyclone is the general name of tropical depression, tropical storm, severe tropical storm and typhoon or hurricane. In USA, people don’t use the name of severe tropical storm and typhoon. Instead, people use the name---- hurricane. All over the world, people name these tropical cyclones according to their strongest speed of wind. Can you guess how fast a typhoon can move? (Show the form to the Ss)
(Look at the form --- tropical cyclone naming conventions )
(Then the teacher shows the map of the world, ask Ss to tell the difference between typhoon and hurricane.)
Step 4 While reading
Fast reading: skim the passage and try to get the general idea of the text. ( Ss answer the main elements of a story: who, when, where, how)
Careful reading: Ss finish two tasks after reading.
the passage and find the answer to the following questions.
1. Where did the ship meet the typhoon?
2. What was the weather at first?
3. Why did the capital say that it looked as if a typhoon was coming on?
4. Where were they when the full force of the hurricane struck the ship?
5. What should they do in such terrible weather?
6. What does the sentence “ Another one like this, and that’s the last of her” mean?
7. Why did the capital strike a match? What did he see?
Task2. Try to explain the difficult sentence in bold in English.
1. It was fine, for there was no wind and the heat was close.
2. Because he observed the barometer fell steadily and he knew that a terrible storm would come soon.
3. When the hurricane struck the ship with full force, they were all on the bridge.
4. They could only move the ship over the high sea and into the very eye of the wind.
5. It was the lowest reading he had ever seen in his life
(If Ss couldn’t understand the sentences, allow them to discuss with their partner.)
Deal with language points after that.
1. on board = in or on ( a ship, an aircraft or public vehicle)
eg. 1) Have the passengers gone on board yet?
2) 一上船， 我总想吐。
As soon as I’m on board I always feel sick.
2. close adj. = lacking fresh or freely moving air
eg. She noticed that the air was very close.
The atmosphere in a steam- heated building is often close
3. dirty adj. = ( of the weather ) rough and unpleasant
k about = knock around ① “ 漫游, 流浪” ② “ ( 狠 )打”
eg. He has knock about all over Europe.
After he graduated from college, Joe knocked about for a year seeing the country before he went to work in his father’s business.
They say he knocks his children about.
5. all of a sudden = suddenly / unexpectedly
eg. 1)All of a sudden, the tyre burst.
2)他转过身来但是忽然跌倒了.
He turned around but fell down all of a sudden.
6. do for sb./ sth. “破坏, 使…失败.”
eg. 1) The spelling mistake in the exam did for him.
2) 若资金不能在十五天内到位，工厂就完了。
The factory will be done for it if capital can’t arrive in fifteen days.
do for “ 设法弄到” 常用于how , what 开头的疑问句中.
eg. How did you do for food when you were in the desert?
7. as though = as if
eg.1) I remember the whole thing as if it happened yesterday.
2) She felt as if the girl were a member of her own family.
8. all at once =suddenly and unexpectedly/ at the same time.
9. swear v. = promise or declare formally
Step 4 Post- reading
T: We have dealt with the language points of the text and now let's do some exercises.
Task 1. Fill in the blanks with proper words.
Task2. Ss discuss the end of the story in groups and one reported it to the class.
(The Ss can express their own opinions and communicate properly. They can improve their speaking skills and the ability to do things in English.)
Step 5 Discussion
Extended discussion:
T: We know typhoon can cause great damage to our life. How can we reduce the loss? How can we protect ourselves?
( Ss discuss in pairs or in groups and then report what they discuss. )
Suggested answers :
1. Build strong houses;
2. Forecast correctly;
3. Give efficient first aid;
up the branches of the trees;
the lines under the ground
T : Every coin has two sides, so does the typhoon. Though the typhoon causes damage, it can have good effects. Can you think of some?
good effects:
eg 1. Bring in enough water to release drought
2. Bring in heavy wind which can be used to make electricity.
step 6 Homework
homework:
Suppose you are a newspaper reporter and are interviewing the capitain. Make up the dialogue.
Think it over: What quest
