教材分析(Analysis of the teaching material)
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(fēng)、火山等自然災(zāi)害發(fā)生時的現(xiàn)象及帶來的影響。通過各個部分的學(xué)習(xí)，學(xué)生初步了解各種自然災(zāi)害及對人類帶來的危害，從而增強(qiáng)保護(hù)環(huán)境和自我保護(hù)意識。
“熱身”(Warming up) 通過四張圖片引出自然現(xiàn)象：火山、臺風(fēng)和彗星及進(jìn)行科學(xué)研究的儀器。通過師生問答形式，學(xué)生能描述自然現(xiàn)象并對臺風(fēng)、火山等自然災(zāi)害有初步了解。根據(jù)圖式理論，將新學(xué)知識與學(xué)生已有的知識結(jié)合起來，能激活學(xué)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(xùn)練為以下各部分的學(xué)習(xí)打下基礎(chǔ)。
“聽力”(Listening) 是一則天氣預(yù)報。短文中出現(xiàn)了對各種天氣的描述及美國各部分的氣溫情況。首先是細(xì)節(jié)題，根據(jù)聽力短文指出美國哪些地區(qū)有雨及周二各部分的最高溫。學(xué)生通過該部分練習(xí)來訓(xùn)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(dá)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(fēng)來時的情形和心理感受，為第二部分的配對練習(xí)打下基礎(chǔ)。第二部分以六幅圖片的內(nèi)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(chǔ)。
“讀前”（Pre-reading）部分先以兩幅圖片來激活學(xué)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(xué)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(jīng)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(xué)生可以學(xué)習(xí)樂于助人、勇于奉獻(xiàn)科學(xué)研究的精神。
“讀后”(Post-reading)分三部分。第一部分通過brainstorming學(xué)生對火山及發(fā)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(xué)生能加深對Pliny個人品質(zhì)的認(rèn)識。第三部分針對課文理解，通過填寫表格培養(yǎng)學(xué)生的概括能力及描述事件的能力。
“語言學(xué)習(xí)”(Language study)分詞匯和語法兩部分。通過詞匯練習(xí)來鞏固本單元的生詞，并且學(xué)生能正確使用現(xiàn)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(xué)生自己探究省略的幾種情況；再通過控制性練習(xí)掌握如何使用省略句；最后通過理解情景對話達(dá)到運用的目的，也就是能用英語辦事。
“學(xué)習(xí)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(xué)生了解故事情節(jié)：“南山”號輪船在駛回福建途中遭遇臺風(fēng)。更猛烈的大風(fēng)即將襲來，整艘船危在旦夕…結(jié)尾部分給學(xué)生留下想象空間。寫作部分是閱讀的延續(xù)，學(xué)生通過想象描述“南山”號是如何脫險的。通過該部分教學(xué)不僅能提高學(xué)生的讀寫的語言技能能力，還能培養(yǎng)學(xué)生的創(chuàng)新思維能力。
“學(xué)習(xí)建議”(Tips) 給學(xué)生提供間接了解自然災(zāi)害的方法，從而培養(yǎng)學(xué)生自主學(xué)習(xí)能力。
“復(fù)習(xí)要點”(Checkpoint) 總結(jié)了本單元的語法重點---省略句。再通過一個問題幫助學(xué)生概括本單元的重要詞匯。
各部分在練習(xí)冊中都有相應(yīng)的鞏固練習(xí)。其中語言技能訓(xùn)練是課文的延伸和擴(kuò)展，培養(yǎng)學(xué)生的說、讀、寫能力。在訓(xùn)練三種技能時增強(qiáng)學(xué)生探究能力和合作意識。
2.教學(xué)目標(biāo) (Teaching aims)
根據(jù)《普通高中英語新課程標(biāo)準(zhǔn)》（實驗稿）關(guān)于總目表的定位及其實現(xiàn)途徑和目標(biāo)具體描述，結(jié)合高二學(xué)生實際和教材內(nèi)容，我們把本單元的教學(xué)目標(biāo)定為：

How to use what the students have learned to describe a nature disaster.
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
Page74,Speaking.Get the students to read the dialogue to find out the answers to the following questions:
1 What happened in the typhoon?
2 What else do you know will happen in a typhoon?
3 What was people’s emotion?
4 What do you think happens in a hurricane, a volcano, an earthquake, SARS and bird flu?
Step5 Speaking
Give the students some pictures. Get them to make a similar dialogue. Tell their partners whether these things or situations frighten them and explain why. Also, talk about people’s emotion in these situations and how they would behave. Get them to make with the help of the useful expressions.
Model:
A: Have you been in a situation that frightens you?
B: Yes. It was last summer. I spent my summer vacation in my hometown, a small village in a mountainous district. One day, I went hiking with my cousin. On our way home, we met a cobra.
A: Were you frightened when you saw it?
B: Very! It made my hair stand on end. My cousin was too frightened to move at that time, too. Because we both saw on TV that the poison of a cobra can kill a person easily.

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.

5. all of a sudden = suddenly / unexpectedly
eg. 1)All of a sudden, the tyre burst.
2)他轉(zhuǎn)過身來但是忽然跌倒了.
He turned around but fell down all of a sudden.
6. do for sb./ sth. “破壞, 使…失敗.”
eg. 1) The spelling mistake in the exam did for him.
2) 若資金不能在十五天內(nèi)到位，工廠就完了。
The factory will be done for it if capital can’t arrive in fifteen days.
do for “ 設(shè)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.
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;
4.Cut up the branches of the trees;
5.Bury the lines under the ground
