UNIT 10 (2A)FRIGHTENING NATURE
1 地位與作用 (Status and function)
本單元的中心話題是“恐怖的自然”。圍繞這一話題討論了臺風、火山等自然災害發生時的現象及帶來的影響。通過各個部分的學習，學生初步了解各種自然災害及對人類帶來的危害，從而增強保護環境和自我保護意識。
“熱身”(Warming up) 通過四張圖片引出自然現象：火山、臺風和彗星及進行科學研究的儀器。通過師生問答形式，學生能描述自然現象并對臺風、火山等自然災害有初步了解。根據圖式理論，將新學知識與學生已有的知識結合起來，能激活學生已有的圖式，有利于新知識的掌握。通過這個階段的語言訓練為以下各部分的學習打下基礎。
“聽力”(Listening) 是一則天氣預報。短文中出現了對各種天氣的描述及美國各部分的氣溫情況。首先是細節題，根據聽力短文指出美國哪些地區有雨及周二各部分的最高溫。學生通過該部分練習來訓練捕捉信息的能力。然后通過問題加深對短文的理解，最后達到能用英語做事的目的。
“口語”(Speaking)由兩部分組成。第一部分是兩人之間的對話，描述臺風來時的情形和心理感受，為第二部分的配對練習打下基礎。第二部分以六幅圖片的內容話題，通過對話的形式來表述情感、焦慮和恐懼，為以后的寫作打下基礎。
“讀前”（Pre-reading）部分先以兩幅圖片來激活學生已有的圖式，對火山的形成有精確的理解。再通過三個問題，學生通過略讀對以下的閱讀材料有個總體的了解。
“閱讀”(Reading)部分描述了“我的叔叔”--Pliny的死亡經過。Pliny不顧個人安危營救朋友，并在旅途中把自己的見聞記錄下來，為后人留下寶貴的研究資料。從Pliny身上學生可以學習樂于助人、勇于奉獻科學研究的精神。
“讀后”(Post-reading)分三部分。第一部分通過brainstorming學生對火山及發生時的情形有更全面的了解。第二部分以尋找問題答案的形式，學生能加深對Pliny個人品質的認識。第三部分針對課文理解，通過填寫表格培養學生的概括能力及描述事件的能力。
“語言學習”(Language study)分詞匯和語法兩部分。通過詞匯練習來鞏固本單元的生詞，并且學生能正確使用現在分詞和過去分詞作表語。本單元的語法是“省略句”，主要包括省略主語、謂語、不定式及多種成分省略；先通過一些例子讓學生自己探究省略的幾種情況；再通過控制性練習掌握如何使用省略句；最后通過理解情景對話達到運用的目的，也就是能用英語辦事。
“學習技能”(Integrating skills) 部分包括讀、寫兩部分，讀為寫做鋪墊。首先通過閱讀學生了解故事情節：“南山”號輪船在駛回福建途中遭遇臺風。更猛烈的大風即將襲來，整艘船危在旦夕…結尾部分給學生留下想象空間。寫作部分是閱讀的延續，學生通過想象描述“南山”號是如何脫險的。通過該部分教學不僅能提高學生的讀寫的語言技能能力，還能培養學生的創新思維能力。
“學習建議”(Tips) 給學生提供間接了解自然災害的方法，從而培養學生自主學習能力。
“復習要點”(Checkpoint) 總結了本單元的語法重點---省略句。再通過一個問題幫助學生概括本單元的重要詞匯。
各部分在練習冊中都有相應的鞏固練習。其中語言技能訓練是課文的延伸和擴展，培養學生的說、讀、寫能力。在訓練三種技能時增強學生探究能力和合作意識。

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?

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
1.Check the homework
2.Retell the story ( if the teacher likes )
3.Review 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.
Task1.Scan 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， 我總想吐。
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
4.knock 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.

do for “ 設法弄到” 常用于how , what 開頭的疑問句中.
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.

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;
4.Cut up the branches of the trees;

2.Listen to the tape and do Exercises 1,2 & 3.
3.Listen again and finish all the questions in this part.
(If necessary, play the tape again.)
Stage 2 Reading
1.Lead-in
Ask the Ss to describe a kind of weather and what people do in such weather.
Today we’ll read some book descriptions about natural disasters and stories that happened in terrible weather.
2.Pre-tasks
Read through the book descriptions and match them with the following book titles.
1. Volcano & Earthquake
2. Under the Volcano: A Novel
3. Disaster! The Great San Francisco Earthquake and Fire of 1906
4. Volcano & Earthquake
5. The Coming Storm: Extreme Weather and Our Terrifying Future
6. Hidden Big Island of Hawaii: Including the Volcanoes National Park
7. Sudden Sea: The Great Hurricane of 1938
(This activity aims to improve the Ss’ reading ability of skimming and the Ss can get the general idea of each paragraph.)
3.While-tasks
Ask the Ss to read the descriptions carefully again. Divide the whole class into two parts. Each part deals with one of the following two activities:
1. Which books on the list interest you? Give reasons why you might want to read them.
2. Choose one book from the list which you don’t want to read and explain why you think it won’t interest you.
(This activity is to help the Ss develop the ability of scanning and express their own opinions with their own words.)
4.Post-tasks
Group work.
Imagine your teacher asks you to write an essay about human experiences and how people suffer during natural disasters. Which books would you choose to help you write your essay? What information do you think you could use from them?
Stage 3 Writing
1. Brainstorming
What natural disasters do you know?
2. Writing
Divide the class into six groups. Each group discuss a topic and writes a composition together. After they finish the writing, they should do peer-revision. Then the teacher will post the compositions on the wall. Each composition should contain the following parts:
1.How is the disaster formed?
2.What happens when the disaster comes?
3. What is the damage after the disaster?
4.What do people do after that?
5. What lesson have you learn?
(This step tries to develop the Ss’ cooperative ability and writing ability. The Ss look up information in many different ways.)
Stage 4 Homework
Read more passages about natural disasters. They can refer to some websites.
Period 6 Grammar & Word Study
Goals: 1. Learn and master Grammar: Ellipsis
2. Review the usage of the present participle & past participle.
Teaching Important Points:
1.Learn about Ellipsis of different types.
2.Enable Ss to learn how to choose the present participle & the past participle.
Teaching Difficult Point: How to use Ellipsis to make a sentence brief and clear.
Teaching Aids: a computer & a projector
Procedures:
Step 1: Word Study
1. Check the answer to Exercise 1 at Page 77.
2. The Present participle & the past participle
T: Look at the 2 sentences on the blackboard.
This is a moving story.
The boy is deeply moved by the story.
Can you tell the difference between “moving” & “moved” ?
S: Yes. The present participle “moving” expresses an action that happens around the same time as the main verb with an active meaning while the past participle “moved” expresses an action that is completed with an passive meaning. Am I right?
T: Yes, quite right? Please open your books at Page 78. Look at Ex. 2. Read the sentences and fill in the blanks with the proper forms of the words.
Step 2: Grammar - Ellipsis
T: Look at the 2 sentences on the blackboard.
Upon arrival, my uncle hugged Pompy and (?) tried to give him courage.
Then came a smell of sulphur, and then (?) flames.
Read them and decide which words were left out at each place of the question marks.
S: I think in the 1st sentence the subject “he or my uncle” was left out.
S: In the 2nd sentence I think “came” should be at the place of the question mark.
T: You are right. In modern English there is a tendency to omit or leave out some words in a sentence for the sake of conciseness. The omission is called “Ellipsis”, and a sentence containing such an elliptical sentence. A word or words in a sentence can be omitted only on condition that the omission would not cause the sentence to be understood in more than one way to be unclear meaning or wrong. We must keep in mind that we should not omit words necessary for clearness. Are you clear about that? Now I’d like to some more about “Ellipsis”.
