The sky is yellow.T: Can you see the buildings clearly?S1: No, they are not clear.T: Thank you, sit down please.S2: In the second one I can find some buildings, but I cannot see them clearly.

Thank you.S4: In the next picture, I can see many people riding bikes wearing masks. The weather is very cold, because they wear gloves and more clothes.T: How about the air?

Now, complete the sentences using the correct form of words in the box. Three minutes.Answers: sandstorm, lasts, frightening, blows, buried,After 3 minutes, ask some students to share their answers.T: From this short paragraph, we can see the sandstorm is frightening. Have you ever experienced the sandstorm? How does it be created? Before we discuss these questions, lets look at some words on the screen.Dig, earthquake, protect, sign, the Pacific Ocean(show the words on the screen, and explain the meaning to the students. Divide the whole class into several groups to discuss questions in activity 2. Then call back the answers)S1: Most of the sandstorms begin in desert areas. Because there are no trees and grasses in the desert areas. The wind is very strong.S2: Climate changing can create deserts, but nowadays, the deserts are being enlarged because of humanity.S3: Deserts are also created because people cut down trees and dig up grass.T: Why people cut down trees?S3: They want to get wood or to plant crops.S4: Few years ago, Japan was affected by the sandstorms coming from northwest China. And America is also affected by sandstorms. Some are caused by humanity; some are from Asia blown across the Pacific Ocean. Sandstorm has been a global issue.T: Very good, thank you. Can we prevent it?S5: Yes. At present, our China has carried out many plans to prevent sandstorm. For example, China has formed a professor committee to study how to prevent sandstorms. We have planted many trees every year. Cutting down the trees is unlawful. The degree of sandstorm is on decline. So we can prevent it. We believe ourselves.T: Quite right. I believe too. Where does the sandstorm often happen?S6: the inland region has more sandstorms than the one near the sea. Because the inland is drier than the one near the sea.T: Can you give us the reason?S6: Dry weather is one of the main reasons for sandstorms.T: Quite right. Youve done very well. From this activity, youve got much information on sandstorms. Sandstorm is very bad. It pollutes the air, affects our daily life. If you are in a sandstorm what should you do? Now work in pairs to discuss the questions in activity 3.(5 minutes later, call back the answers)S1: If I am in a sandstorm I will wear a mask to protect my mouth and throat, wear a pair of glasses to protect my eyes.S2: Besides mask and glasses I will wear a hat. Because there is much sand in the air, it will make my hair dirty.T: You are right. In a sandstorm, you should wear a mask and a hat, a pair of glasses is also necessary. Which one is more dangerous, earthquake and sandstorm?S3: I think earthquake. Because in sandstorm we can stay at home to protect us, but in earthquake everywhere is dangerous.T: I agree with you. Where in China do sandstorms usually happen? What is the first sign?S4: In the west and northwest China.S5: But it also happens in Beijing often.S6: Before the sandstorm, there is usually a heavy wind and dry weather.S7: The sky is yellow.S8: One afternoon of last spring, when I was at school, the sky was yellow. There was much sand in the sky. The wind was very strong with some drops of rain. In fact, it was not rain. It was mud. At that time, I thought the earthquake was coming. It was very terrible.T: It was really terrible. Thank you. Now I think all of you have known about something of sandstorm. The sandstorm is terrible and harmful. We should work hard to protect our environment.Step III Pronunciation and FunctionListen to the tape and ask students to underline the words stressed and conclude when and where the word will be stressed. Then ask students to practice activity 1&2. Listen again to check if the stress is right. Ask students to complete the sentences in Ex.3 using expressions from Ex.1&2. Step IV Talking T: Suppose you are a citizen. There is a sandstorm in your city. A reporter wants to interview you about this sandstorm. Make a dialogue about your interview with your partner.S1: Good afternoon sir, I am a reporter of local television station. May I ask you some questions about the sandstorm happened in the morning?S2: Ok.S1: When the sandstorm happened, what were you doing?S2: I was cycling on the road.S1: Before the sandstorm coming, did you know it was the sandstorm? Or were there some signs of the coming sandstorm?S2: Yes. I learn some sandstorm signs from TV. So I tried hard to ride, but the wind was so strong.S1: Can you tell me some signs of that sandstorm?S2: First, the wind was becoming stronger and stronger, it looked like the rain was coming. I can hardly ride my bike. The dust on the ground was whirled into the sky. And the sky was turned into yellow. The dust became more and more. I can hardly open my eyes. I knew it would be a sandstorm. S1: It was terrible. Can you give us some ideas to prevent the sandstorm?S2: From television, we can see most of the sandstorms are caused by human. Instead of cutting down trees and digging grass we should plant more trees and grasses. S1: I agree with you. I think after this sandstorm most of people will be waken. Thank you.T: Well done. Thank you. Now we have known most of the sandstorms have been caused by the destroyed environment. Are there any other things that are bad for the environment? Ss: Yes. For example, coal.T: In what way?Ss: It gets off lots of smoke and pollutes the air.T: Youre right.Ss: Plastic. In our daily life, people use many plastic bags and throw them around. When there is wind, the plastic bags thrown will fly everywhere. Ss: In canteen many students use plastic bags to hold their meal and throw them away then. I think we should not use them first and set a modal.Ss: Like refrigerator, more and more cars have come into families. They give out much chemical smoke, especially in cities. It is bad for our health.Ss: Cutting more trees will not only cause sandstorms but also enlarge the sand area. T: Well done, boys and girls. Since we have known so many things are bad for the environment, what should we do to protect our environment?Ss: We should plant more trees to fresh our air.Ss: We should throw the rubbish into the dustbin and not throw them anywhere.Ss: I think the most important thing we should do is to organize an organization to make people around us know the importance to protect the environment. T: Ok, what you talk about is very helpful. Please prepare it after class if you want. If you need help, please let me know. This class we have learnt something about sandstorms, and have discussed things that pollute the environment. Since the pollution is so serious, we should try our best to protect our environment. Now what you should do after class is to turn your idea into practice. Step V Assignment1. Write a composition according to the pictures.

Who wants to share your short passage about the pollution around you?Ss: Id like. Our earth used to be a beautiful place. Thick trees and green grass covered the hills and it was the best home for birds and animals. What a beautiful scene it was! However, as time went on, people destroyed the forest to grow crops. What were worse, people let their cattle eat up the grass. So you can see a stretch of wasteland instead of green hills now. As a result, when it rains, the soil is washed down the hills, strong winds blow away the rich soil that lies on the top of the fields. We do hope all the people will take good care of our forests and plant more trees to improve the environment in which we are living. Im sure as long as we try every possible means; were sure to have a beautiful environment again.T: Excellent! Thank you. Yesterday, we have talked about something about sandstorm.
