If necessary, offer the following words: damage, give out, environment, carbon dioxide, chemicals, pollute, white pollution, dig out, desertification.

                                                                     

2. Ask Ss to discuss the causes of environmental pollution and make a list. Then collect the information.

For your reference:

(1) Serious air and water pollution.

(2) Cutting down too many trees.

(3) Desertification.

(4) The growing population of the world.

(5) Climate changes.

(6) Waste in the use of water.

(7) High temperature and little rain.

(8) Gas from the running cars.

(9) Plastics in the rubbish.

3. Ask Ss to do discussion:

  (1) Ask Ss to work in pairs and think of several things we need to do to improve the environment and say why.

  (2) Ask each pair to compare the solutions with another pair. Then work in groups and choose two solutions that they are the most important.

(3) Choose a group number to tell the class why these are the two most important solutions.

For your reference:

Control water and air pollution.

Build green fences along the desert.

Reduce the number of the population.

Produce new types of cars.

Plant more trees.

Reduce the number of the cattle to protect the grass land.

    Prevent people using plastics bags as containers.

4. As senior high students, what should we do to improve our environment in our daily life?

Step3. Writing

1. Ask Ss to work in pairs and talk about two or three environmental problems. Make notes and write down the key words and phrases. Here are some sentence patterns:

One major environmental problem is

There is a problem with.

2. Ask Ss to work in pairs and find out as many solutions as possible to the problems and write down the key words and phrases.

  Here are some suggestions for language.

  We should

  We need to

  We must

3. Ask Ss to write down the problems and solutions. And then write two or three sentences to summarize.

One example: One major environmental problem is cars, because they pollute the air with carbon dioxide. We need to find a cleaner way to travel. People should cycle and walk more.

4. Ask Ss to exchange their writing with a partner for peer correction of content, structure and language.

One possible version

   Humans change the environment in many ways and the most serious environmental problems are air pollution and water pollution.

With the development of industry and agriculture, the air and water have been seriously polluted, which is doing harm to us human beings. And many kinds of wild animals are dying out. So we must get a clear understanding of the dangerous situation we are in and take some measures. For example, it is important to deal with the rubbish in cities. Rubbish must be treated properly, or it may pollute the air and water. And when people breathe polluted air or drink polluted water, they may get ill. So some rubbish should be sorted and sent to different factories. Rubbish, such as old newspapers and glass, should be recycled; some harmful rubbish should be sent to certain places and buried. At the same time, waste gases must be cleaned before they are returned to the air; and waster water needs be treated before flowing into rivers.

In a word, it is a duty of everybody to solve the problem and we should put into our hearts how important it is to protect the environment.

Step 4. Task

Ask Ss to design a poster that encourages people to look after the environment. Write down Ss suggestions to encourage people to take actions.

Step 5. Module File

Ask Ss to look at Module File on page 20 and try to recall what they have learnt in the module. Then tick the things they are sure that they know and put a question mark next to the points they are not sure of and a cross to what they dont know. Help Ss to share their ideas and deal with the difficult or confusing points.

Ask Ss to read some articles or novels about sports to strengthen their reading skills and enlarge their vocabulary.

Step4. Homework

1. Ask Ss to review Module 4.

2. Ask Ss to preview Module 5.
