VI. What will happen to our planet if the present trends continue?

6. I have prepared for you some texts. Each group will get its own one. While reading you should use the scheme which is called Fishbone. I'd like to remind you what it is. It's a special scheme that helps us to structure the text. The main problems are put in the head, upper bones are used for reasons (why the problem exists), lower bones are used for facts proving the existence of the reasons. Facts give the problem clear outlines. Your notes should be short. Use key words, contractions and exact details from the text. In the end you should come to the conclusion (or find possible ways to solve the problem) and put it in its tail. You will choose one representative from each group to announce the answers.(слайд 41)

Text №1 (1 group) (Приложение 5)

Text №2 (2 group) (Приложение 6)

VII. Revision of grammar: Modal verb "Should". 5 мин.

T: We should save our nature!

What does modal verb "should" express?

P: It expresses advice.

T: Right you are: it expresses mild obligation or advice.

Can yo?? give examples? Open your exercise books and do it in written form.

VIII. Evaluation. 1 мин. 3-й блок. Понимание полученной информации

Ok, now you should answer the questions.

(учащиеся отвечают на вопросы после заполнения таблицы. Задание направлено на выявление понимания не только прочитанного, но и прослушанного)

4. Let's summarize and analyse all the information about the problem. We have made a special scheme which is called a "cluster". It shows the ways of our thoughts. It is a structure of our thinking. Consult the cluster on the screen and decide if we have missed anything important.Would you like to add anything? Of course, the list of serious ecological problems could be continued. We can also mention such burning issues as nuclear pollution and shortage of natural resources.(слайд 39)

5. Now I'd like to ask you some questions. They are fishing questions and shooting question. Fishing Questions(FQ) are exploratory. We may roughly know the area of the answer or sometimes we know this more exactly and sometimes we know it hardly at all. With an FQ we are exploring and trying to find things out.

With a Shooting Question we are not exploring but checking up on something. An SQ always has a "yes" or "no" answer. In other words the question can always be put in a way that could be answered with a "yes" or a "no." So in a shooting question we know what the answer might be and we are just checking to see whether or not it is so. A shooting question is specific and aimed.

I'll appreciate all your answers.

1. What are major environmental problems?

2. What can cause air pollution?

9. What is being done to protect the environment?

The throw-away society

Many countries bury and forget millions of tons of rubbish every year. But we don't have to throw away all waste paper, glass, metal, plastic. We can also burn or recycle a lot of it. In fact waste can be very useful stuff.

1. Britain is well on the way to being swamped by rubbish. Every year each family offers the dustmen one ton of "mixed waste"(two black sacks a week), but we can recycle most of this.

If we recycle things, we can save money, energy and natural resources. Recycling the Sunday New York Times newspaper, for example, will save 75,000 trees every week.

2. More than half of the dustbin content is a combination of paper (33%) and vegetable matter (20%). The rest includes glass (10%), dust and ash (10%) and smaller quantities of metals, plastics and textiles.

3. How do we get rid of this rubbish? We find or dig huge holes in the ground and fill them with this stuff. These are known as "landfill sites".

4. This 20 million ton of rubbish pose major environmental problem polluting the area. In is a slow and unseen menace. Methane gas given off by decaying organic matter can build up and explode. Toxic materials poison the water and air and pose a long term threat to our food chain.

Moreover, a lot of rubbish is not biodegradable. Plastic, metals and chemicals will not disappear for hundreds of years. So we must avoid using non-biodegradable materials.

5. But a lot of what we throw away is still useful. The glass, plastic, metal, oil, textile, paper, cardboard, battery content we send to landfill is potentially very valuable because it is a concentrated source of many raw materials. Rubbish can be also burn to generate electricity and heat our homes.

6. Britain recycles less than 1, 5% of waste. It is a pretty poor record if compared to 10% in the US and Germany, 14% in the Netherlands, 18% in Canada. There is a problem- recycling is expensive. But it should be sponsored by government, local councils and industry.

G. Still the number of recycling centers is growing. Collection "banks" and kerbside "blue boxes" have become very popular. Consumers separate materials (paper, metal, textiles, glass, cans, plastic containers) and take them to collection points. It cuts waste going to landfill by half and reduces pollution.

H. There are over 350 power stations in the world that make electricity from rubbish. Most of them are in Europe and Japan.

In London, a power station burns 400,000 tons of rubbish a year. This heats water that makes steam. The steam turns a generator.

In New York, a power station burns 2250 tons a day. It makes electricity for 70,000 people. However, New York produces 10 million tons of rubbish a year. Most of it is never used again.

swamp- затоплять, утоплять

sack- мешок

textile- текстиль

landfill- мусорная яма; site- свалка

kerbside- обочина

Animals in danger

Perhaps the most famous rare animal is panda. Twenty years ago it was nearly extinct. Now, its numbers are growing again. It even became a symbol for wildlife conservation. But many other species have been less lucky than the panda.

By the year 2030, 25% of all animals, birds, fish and insects may be extinct. Why is this happening? Well, there are some three main reasons. The first is pollution. Millions of animals die every year because man has polluted their natural home or "habitat". A habitat contains everything a living thing needs: food, water, shelter, space, light.

Pollution and destruction change the balance of nature. Each species in a habitat-wood, jungle, marsh or forest- needs and helps the rest. If one animal, bird or insect disappears, all the rest suffer too, because some plants and animals provide food for other animals. Forests help to regulate water supplies. We all need the help of all living things to maintain chemical balance of the atmosphere.

After pollution or destruction, habitats take many years (sometimes hundreds or even thousands) to grow again. This is what's happening in the rainforest of South America, Africa and Asia. There are some of the world's oldest habitats.

Or they were. But the problem doesn't stop there.

The second reason is the environment itself. It is becoming smaller. Every year man cuts down more trees, builds more roads and uses more land for farming. This leaves fewer jungles, fields and forests for wildlife. In fact scientists believe that thirty British animals, fish, birds may become extinct by the beginning of the 21^st century.

Today, many more species are in danger not only because man destroys and pollutes their habitat, but because man hunts them. Man has always been a hunter. He still is. But many modern hunters don't kill for food- they kill for profit. That's why so many rare and protected animals are still dying. Hunters like these are called poachers. In 1981 there were 15,000 black rhinos in Africa. Today because of illegal hunting, that number is 4,500.

There is only one way to save animals and wild habitat-conservation. If it doesn't happen, many wild animals will soon have just one habitat-the Zoo.

Marsh-болото, топь

Rhino-носорог

Conservation-сохранение, создание заповедников

Profit-доход, выгода

Shelter-убежище, приют

Poacher- браконьер

Maintain-поддерживать5. Now I'd like to ask you some questions. They are fishing questions and shooting question. Fishing Questions(FQ) are exploratory. We may roughly know the area of the answer or sometimes we know this more exactly and sometimes we know it hardly at all. With an FQ we are exploring and trying to find things out.

With a Shooting Question we are not exploring but checking up on something. An SQ always has a "yes" or "no" answer. In other words the question can always be put in a way that could be answered with a "yes" or a "no." So in a shooting question we know what the answer might be and we are just checking to see whether or not it is so. A shooting question is specific and aimed.

I'll appreciate all your answers.

X. Подведение итогов урока.

The topic of our today's conversation was very serious. There are a lot of problems but, unfortunately, we don't have enough time to discuss all of them.

Today environmental issues are much spoken and written about on TV, radio and in the newspapers. Fortunately, it's not too late to solve these problems. If we take actions now, there might be some hope for the future.Together we can save the planet and all of us with it. If we want to survive, we must do our best to solve these problems.It is important to join our efforts in the struggle for survival. We are responsible for preserving our planet for future generations. The life of future generations depends on our attitude towards environment and the way each of us treats nature.

We'll have to stop now. That's all for today.I'd like to thank you for good work at the lesson. All of you worked very well. I give excellent marks to..., good- to :, etc. I wish you good luck.

The lesson is over. See you later. Goodbye!
