Q6: What will you feel in such kind of weather?
frightened, scared, terrible, happy (Ask the students why they feel happy? ---- Because typhoon will often release the drought. What’s more there is enough water, which can be used to make electricity.)
Q7: What about the hurricane? Have you ever heard about it?
It is something like typhoon.
Q8: What about volcano?
Q9: Look at the picture. Find out as much as you can to describe it.
eg. eruption lava
Q10: How is a volcano formed?
1). Show a video about the eruption of a volcano.

Q11: Where is the most possible place that a volcano may erupt?
Near the ocean. eg. Fujiyama mountain in Japan.
Q12: Do you know how a volcano works, if you do, describe it?

Period 3 Listening(Wb) Speaking & Talking
Goals:
1) Understand the listening text in the workbook.
2) The Ss can express emotion, anxiety and fear properly.
3) Know more about typhoon.
Teaching important points:
To master the useful new words and expressions.
Teaching difficult points:
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.
A: What happened next?
B: Fortunately it didn’t see us. We acted just as the TV programme told us. At last, it went by. The distance between the cobra and us was only three metres or so.
A: How terrible!
Step6 Pre-talking
Ask: What do you need to do when you are trapped in a typhoon?
Get the students to read the dialogue at Page144, Talking between Xiaosong and David to find out what Xiaosong suggests in case of typhoon.

1) What was it like?
2) What happened?
3) What was people’s emotion and what about yours?
4) What safety measures should be taken?
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
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.
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.

1. Build strong houses;
2. Forecast correctly;
3. Give efficient first aid;
4.Cut up the branches of the trees;

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

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”.

附录一 背景资料 (Background knowledge)
1 ．Volcanoes
There are thousands of volcanoes allover the world. What makes volcanoes? What happens?
The inside of the earth is very hot. Because it is very，very hot，the rock has melted like ice. It has become liquid，like water. It is always boiling，like water in a kettle. If you have seen a kettle boiling，you know that the steam and boiling water try to get out. The very hot melted rock inside the earth also tries to get out. Usually it cannot because the outside of the earth is too thick and strong.
But in some places the outside of the earth is thin and weak. Sometimes a crack（a small opening）appears. The hot melted rock ．which we call“lava”，pushes up through the crack and bursts through. Steam and gas shoot up into the air and the hot melted lava pours out. Big pieces of rock may be thrown high into the air.
After a while the volcano becomes quiet again. The melted lava becomes hard. Later the same thing happens again and again. Each time more hot lava pours out on top of the cold lava and then becomes hard. In this way a kind of mountain is built up，with a hole down the middle. Perhaps the volcano will then be quiet and no more lava will burst out. Perhaps it will start again hundreds of years later.
Although there are thousands of volcanoes in the world，most of them are dead. On1y about 500 sometimes start to throw out lava again. A famous volcano which is now dead is Mount Fujiyama in Japan. It is covered with snow in winter.
Vesuvius is the name of a very famous volcano in Italy. It first came to life many，many years ago. It was quiet for hundreds of years. Then in the year 79 it suddenly burst. A great cloud of smoke shot up into the sky with great burning rocks．which fell all around. Hot lava poured down its sides. About 3 000 people were killed.
This has happened again many times since that year. Sometimes no damage was caused，or only little damage. But there was serious damage in the years 472，1631，1794，1861，1872 and 1906.You can see that a volcano can stay alive for many years. In 1906 part of the top of the mountain fell off. There was also serious damage in 1914 but there has not been any since that year.
2 ．What Is a Tornado?
What exactly is a tornado? The general picture is familiar enough. The phenomenon usually occurs on a hot sticky day with south winds and an ominous sky. From the base of a thunderhead，a funnel-shaped cloud extends a violently twisting spout toward the earth. As it sucks in matter in its path，the twister may turn black, brown, or occasionally (over snow) even white. The moving cloud shows an almost continuous display of sheet lightning. It lurches along in a meandering path, usually northeastward, at 25 to 40 miles per hour. Sometimes it picks up its finger from the earth for a short distance and then plants it down again. The funnel is very slender: its wake of violence averages about 400 yards wide. As the tornado 'approaches, it is heralded by a roar as of hundreds of jet planes or thousands of railroad cars. Its path is a path of total destruction. Buildings literally explode as they are sucked in by the tornado's low-pressure vortex(where the pressure drop is as much as 10 percent) and by its powerful whirling winds (estimated at up to 500 miles per hour). The tornado's lifetime is as brief as it is violent. Within a few tens of miles (average: about 16 miles), it spends its force and suddenly disappears.
3.Earthquakes
Earthquake is a sudden, violent shaking of the earth's surface. It's a kind of crustal movement form of expression.
Earthquake is regarded as one of the most damaging forces known to man: since records began to be written down, it has been estimated that earthquake-related fatalities have been numbered in the millions, and that earthquake-related destruction has been beyond count.
The great majority of all earthquakes occur in two specific geographic areas. One such area surrounds the Pacific Ocean and its contiguous land masses. The other extends from the East India to the Atlas Mountains, including the Himalayas, Iran, Turkey, and the Alpine regions. It is in these two great belts or zones that ninety percent of all earthquakes take place. The text refers to two of the strongest quakes in San Francisco. As to our country. a large number of earthquakes happened in North China and Northwest China. The powerful earthquake of Tangshan hap- pened in the city of Tangshan, Hebei Province on July 28th，1976，which caused more than 240 000 deaths and the whole city was destroyed.
Nowadays scientists know a little about earthquakes and they still cannot stop these disasters from happening. However，they can warn people who live in these areas by prediction, in advance to take precautions against such disasters. A worldwide earthquake warning network is already in operation at present and is expected to make earthquake prediction several years ahead of time.
4.5R Policy
It’s important to learn about protecting our environment. Here is a 5R policy for us to consider:
1.Reduce:
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throws it away, before long we would not have any trees left. Other things are also being wasted, and people don’t really know what to do with the large quantities of rubbish produced in large cities, therefore, t is necessary to reduce the amount of waste by every possible means.
2.Reuse:
You should always think of reusing the usable things before getting rid of them. Give your clothes you do not use or the ones which are too small to the poor. Within a family, you may pass on such clothes to younger brothers or sisters. If you wish, you can use buttons and something else to make dolls or toys for your baby brother or sister.
3.Recycle:
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money. For example, coke coca cola cans are sent to a factory, where they are smashed flat and melted and metal sheets are made for new coke cans.
4.Recover:
When you buy a box of apples, there might be a few which are highly rotten. You have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.
5.Repair
If one of the legs of your table is broken, you can have it repaired instead of throwing the table away. If you want to change for better furniture, it is better for you to sell the old things or give them to other people who can use them after doing some repair.
It is true the North America is throe away society, but the time has come to change our way of life so that we can protect our environment. Every one of us should take an active part in it.
