Ход урока

I.Начало урока. Приветствие. Постановка цели.

Учитель: Good afternoon. This lesson is the last one on the topic “Ecological

Problems”. You have to discuss these problems and show what way we can

help. At the end of the lesson you should answer the question: Can you help to

save the planet? Now let’s begin.

А) Повторение лексики предыдущих уроков:

Учитель: First, I’d like to ask you what ecological problems do you know?

Ученики: Acid rain, deforestation, water pollution, air pollution, nuclear pollution,

the greenhouse effect, endangered spiecies…

Учитель: But what is the most important problem? What do you think about it?

Ученик: There are a lot of ecological problems not only in Russia but in the whole

world. To me, the most important ecological problem is pollution.

Учитель: People have always polluted their countries. Some years ago it was not a

serious problem. But now it has become more serious. What are the reasons

for it?

Ученики: (варианты ответов)

I think people throw away too much litter. There is a lot of litter everywhere.

Different kinds of transport make this problem serious.

Many factories don’t recycle. They produce goods a lot of litter.

In my opinion we know the rules but don’t remember them when we go hiking or fishing or just walking in the forest.

Factories and cars pollute the air with harmful gas.

В) Повторение словообразования глаголов, существительных, прилагательных по

теме:

III. Основная часть урока.

Учитель: We have decided to hold this lesson as a press-conference. To the right we

have some environmentalists and wildlife specialists. To the left there are mass media reporters. Now introduce yourselves. Please, specialists first.

Далее каждый учащийся представляет себя как специалиста или репортёра, указывая ту область деятельности, которой он занимается. Ученики представляют свои доклады, которые они готовили во время изучения темы. Ведется дискуссия.

Ученик: - My name is Mrs…I’m a reporter. I work for the magazine “Eco News”.

I’d like to know about the most serious ecological problems on the Earth.

3. (Использование ПК. Документ Microsoft Power Point. Приложение 3.)

(мультимедийная презентация доклада учеником)

Ученик-«специалист»: - My name is Mrs… I’m a doctor of the University of Rome. I’ve been exploring the Mediterranean Sea and its base, the animal and plant world there. The Mediterranean Sea is in danger. Some of its wildlife is unique, but its survival is threatened by pressures from tourism, pollution and overfishing. Millions of tourists visit the Mediterranean each summer, but few have any idea what damage is being done around and below the water. Habitats and their wildlife are disturbed, polluted and exploited, and protection schemes are struggling to cope with the destruction.

Half of the 100 million people who live around the Mediterranean coast live in towns and cities. They, and a great number of tourists, produce sewage that is poured into the Sea. Because there is so little movement of water in and out of the Mediterranean, the sewage is not flushed away but remains, killing the plants and decreasing oxygen in the water.

Доклад несколько раз прерывается вопросами «репортёров»:

Ученик-«репортёр»: Will plastic waste decompose and break down naturally?

Ученик-«специалист»: No, it won’t. Plastic waste, thrown into the sea, is a really big

problem as it is not biodegradable.

Ученик-«репортёр»: How do fishing methods affect the Mediterranean sea and its

wildlife?

Ученик-«специалист»: For centuries, fishing has provided a living for Mediterranean people. However, with new fishing methods, fish stocks are dwindling as modern ships catch huge numbers of fish and less valuable fish are thrown back. This affects other animals in turn including the Mediterranean monk seal. This was once very common but was blamed for competing for fish and killed. The monk seal is now Europe’s rarest mammal with a population of less than 700.

The usage of drift-nets is a big problem. Dolphins are the high profile victims of this kind of fishing, but the other problem is that too many fish are being caught, and often fish which are too young to be caught. Again, because of this system, fish stocks, particularly in Europe, could be exhausted in the next 30 years.

Учитель: - Thank you very much. Your report was very interesting. I fully agree with

your point of view.

Ученик-«репортёр»: - I’m a reporter of CNN. I’d like to clear up one more point.

What about polluted air?

4.(Использование ПК. Документ Microsoft Power Point. Приложение 4.)

(мультимедийная презентация доклада учеником)

Ученик-«специалист»: - My name is Mr… “I’m a doctor of Oxford University. I’d like to tell you about the problems of air pollution in big cities. And I want to show the successful results. I’ve been exploring the technology how to save fresh air in big cities. My report is about English city Sheffield. Sheffield is one of the England’s largest cities. It is an industrial city with lots of plants and factories. For more than a century it was a smoky and dirty city, and the view of chimneys sending smoke and dirt was very characteristic of it. Today it’s one of the cleanest industrial cities in Europe.

Ученик-«репортер»: -How did they manage to improve the environment?

Ученик-«специалист»: -The factories and plants were modified. Modern technology reduced the amount of the waste in the air by special filters. A quarter of a million tulips are imported from Holland each year.

 

Учитель: - Thank you very much. You know that there are organizations in the world which campaign against threats to the environment, one of them is Greenpeace. Let’s see the representative of it, Mr. Brown. What can you tell us about Greenpeace?

5. (Использование ПК. Документ Microsoft Power Point. Приложение 5)

(мультимедийная презентация доклада учеником)

Ученик-«специалист»: -It is the world’s most successful environmental pressure group. It campaigns against the unchecked proliferation of nuclear power, the pollution of our seas and rivers, and the destruction of our rainforests and the natural habitat of people and animals all over the world. Greenpeace has always managed to get worldwide publicity for the many and varied campaigns that it runs. The organization’s headquarters are in Amsterdam, Netherlands, but it has offices in many countries. The biggest office in Central Europe is in Prague. Join us!

Учитель: -We would be glad to see Susan Stevens, environmental campaigner. Unfortunately, she cannot visit our press-conference, because she is busy with the campaign preventing the destruction of some of Canada’s ancient rainforests. But we can see the interview.

Учитель: -Let’s interrupt our press-conference and return to the lesson for a moment. Susan’s answers are in a note form. Try to work out what she actually said. Then listen to the interview and check your answers.

6. (Использование ПК. Документ Microsoft Power Point. Приложение 6)

Упражнение выполнено в программе Microsoft Power Point. Учащиеся по очереди составляют предложения, используя опорный материал с экрана.

Учитель: -Let’s continue our press-conference and listen to the interview with Susan .

Затем прослушивают запись интервью на аудиокассете и сравнивают свои ответы. Текст интервью появляется на экране при помощи эффектов анимации.

Учитель: -What can we do to help environment? Today we are welcome the Head Manager of the local recycling center. Could you inform us about recycling.

7. (Использование ПК. Документ Microsoft Power Point. Приложение 7)

Мультимедийная презентация доклада учеником.

Раздаются листовки центра переработки бытовых отходов. (Приложение 8)

Ученик-«специалист»: One way of helping the environment is by recycling, which

means using again.

There are two main ways of recycling: either you can use things again yourself, or you can take them somewhere so that they can be processed to make something new.

Look at this poster, designed by a recycling centre, there you can find the answers to the important questions.

Ученик-«репортёр»: -How can we recycle the following: tins, jars, old clothes, paper,

gift wrapping paper?

Ученик-«специалист»: Tins - We can recycle tins by taking them to the nearest

recycling centre.

Jars - We can wash out jars and use them to hold small things.

Old clothes - We can give old clothes to charity.

Paper - We can reuse paper to make notes on before recycling it.

Gift wrapping paper - We can reuse gift wrapping paper to wrap up other presents.

And what can we do when we go shopping to help recycling?

We can buy things in bulk rather than in small quantities to cut down on packing and we can check that products we buy have been or can be recycled.

How do you think using computers and e-mails might help?

Using e-mails cuts down on paper and envelopes and so save trees.

Computers store information so we need to buy fewer books.

Ученик-«репортёр»: -What ways of recycling could you offer to help save resources

and energy in schools?

Ученик-«специалист»: -A lot of paper is used in schools and wasted.

Do teachers and pupils need to make so many photocopies?

Often pupils just throw them away afterwards. It would be better to have everything in an exercise book to keep. Perhaps we should also have school text books that pupils borrow and then give back at the end of the year. Pupils who have computers could send in their homework by e-mail to cut down on paper and the teacher could put the correct answers on a special web-site.

What do you do to recycle and help environment? What more could you do?

Ученик: As for me, I reuse paper for notes and I give all my old clothes to charity. I also reuse gift wrapping paper for other presents. However, I know I could do more. I don’t go to the recycling centre as it’s rather long way from my home – I could perhaps go with someone who has a car.

IV. Заключительный этап урока. Выставление оценок. Рефлексия.

Учитель: - Thanks a lot. Our press-conference was successful. At the end of the lesson

I’d like to know if you like it.

Ученики: - In my opinion, the lesson was interesting, because I like the way our

“specialists” show us ecological problems in the world.

- I absolutely agree, because it was new for me to know how to recycle

paper, cans and glass.

Учитель: - And what can you tell us about your work?

Ученик: - I think my work was good, because I was asked some questions after my

report, so “reporters” were interested in the information.

Учитель: Now let’s return to the question I ask you at the beginning of the lesson: Can we help to save the planet?

As for me I think we could help to save our planet if take care of nature.

Учитель: What should we do for it?

- We should help animals. We should care for wildlife. We should recycle paper, cans and glass. We shouldn’t throw away litter. We shouldn’t let fires burn in the forest.

 

Учитель: - Let’s watch а video of one famous band “Weezer” with a song devoted to

wildlife “Island In The Sun”. Let’s sing altogether.
