       I.            Организационный момент:

Good afternoon, pupils, take your seats, please. Good afternoon, dear guests.

Warming-up: I’ve brought an apple for you. Look at it! Isn’t it wonderful? Try to use imagination and to think what the apple looks like. Does the apple remind the earth? And now look! I cut the apple into 4 parts. 3 parts of the Earth’s surface is water and only 1 part is land. Now I take the part representing land and cut it in half. Look only one half of the land is habitable. The rest part of land is deserts, mountains, frozen ice and other places where people can’t live. And now I take the piece that represents the habitable land and cut it into 4 sections. Only one of these parts (of the Earth’s habitable land) is where all the earth’s food comes from. Now look at the 3 parts of the Earth which represent the water. Less than 1% of the Earth’s water is fresh and drinkable. And most of this water tied up in the atmosphere (clouds) and underground.

So, you see how important it is to think about the planet we live on. And today at the lesson we are going to discuss Earth’s problems and even find some solutions for helping it. That’s why the epigraph of our lesson is J. Galsworthy’s words: “If you don’t think about the future, you won’t have it”. The epigraph is not finished try to think and finish it by the end of the lesson. Our planet is the place we live on, and our future depends on how we can keep it. Nowadays our planet has some problems.

Презентация в электронном виде в сопровождении высказываний  учащихся. Thank you girls.

After listening the presentation I want to check your understanding.

Exercise 3. Say if the sentences are true or false; if the sentence is false make it true, please.

1.    Cars, plants and factories put a lot of gases into the air, so it becomes safe to breathe.

2.    The water is so dirty nowadays that it is dangerous for people, animals, fish.

3.    The greatest part of ocean pollution comes from acid rains.

4.    Garbage produced by people disappears quickly and doesn’t pollute the earth.

5.    Each person throws away 2 kg of garbage every day.

6.    Acid rain is a mixture of rainwater with gases released by plants and factories.

7.    Global warming happens because of harmful gases.

8.    We need ozone to breathe, to protect us from the harmful sun heat and rays.

9.    Nearly 80% of Belarusian land is polluted with radiation.

 What is the most acute ecological problem from your point of view and why?  Yeah, they are really acute, but there must be the way out.

 

 

  III. Развитие лексических навыков на основе теста.

Scientists and many other people think a lot and say that there are some ways out.  Read the text and try to find the ways out for our planet, please, fill in the gaps with words derived from the words in brackets and say what preventive actions can help improve the situation. Help me to make up a key formula to success.

Fill in the gaps with words derived from the words in brackets.

There are many problems which (1)_______ (threat) our natural environment. Acid rain, (2)_______ (globe) warming and air and water (3)________ (pollute) are among the most serious ones. There are several ways to help improve the situation. Firstly, we should encourage (4)_______ (recycle) because it is the (5) _______ (produce) of new materials which causes the most damage. We must learn to reuse things like plastic bags and glass jars. Secondly, driving an environmentally-friendly car is also (6)_______ (help). Furthermore, joining an (7)_______ (organize) which plants trees or cleans up beaches would be a (8)_______ (prove) that you are really (9)_______ (concern) about the environment. Lastly, supporting groups such as Greenpeace, which try to prevent many (10)_______ (environment) disasters, would help to ensure that our planet will be clean and safe for the future generations.

You have worked hard, try to relax, imagine that you are a bird or you may watch these beautiful sights, they say nature helps people to relax.  Listen to the sounds of the Earth (музыка).

 

 

   VI. Обучение чтению и монологической речи на основе текста.

Well I suppose you have strength now to work further as the aim of our lesson is to try to help to save this beauty. As we spoke earlier we can recycle, reuse things and reduce the amount of energy we consumpt. One more way out for saving our planet from global warming and pollution is using renewable energy sources. You’ve read the text about the advantages and disadvantages of using renewable energy sources. Answer my questions, please. Remember the pronunciation of these words. (С транскрипцией на доске)

Text for reading

All renewable energy sources are environmentally friendly energy sources but as I always say a perfect energy source does not exist, and this rule also applies to renewable energy sources. From the environmental point of view renewable energy sources are far more acceptable than fossil fuels, mostly because they do not emit greenhouse gases like burning of fossil fuels does, but this does not make them a perfect solution to protect our environment, they are more like the best available energy option we currently have.

Renewable energy sources can also have negative environmental impact in certain area, the major difference in this point between fossil fuels and renewable energy sources is the fact that fossil fuel burning always has negative environmental impact, while on the other hand using renewable energy sources “can” have negative environmental impact.

Wind energy has been over the last couple of years the most popular renewable energy source but despite its popularity this renewable energy source has also been the subject of some rather interesting environmental debates, for instance are large wind turbines really killing thousands of birds with their fast rotating huge blades and do large wind turbines really create significant noise pollution.

Solar energy is renewable energy source that has probably received the least critics from environmentalists but even the abundant solar energy isn’t the perfect environmental solution. The environmental drawbacks of solar energy include the fact that large solar power plants use large quantities of water for cooling purposes which could lead to water shortages, and they also need huge area which could shrink habitats of animals in nearby area.

Geothermal energy is in most cases extremely environmentally friendly energy source but if for instance drilling isn’t done with proper care, it can lead to release of many harmful gases which could cause significant environmental damage.

Tidal and wave power projects can also have negative impact on environment by for instance disturbing or disrupting marine ecosystems by noise and/or visual pollution.

As you can clearly see from above even the renewable energy sources aren’t perfect from the environmental point of view, but are currently the best energy option at our disposal, especially if we accept the fact that ongoing climate change phenomenon is the greatest environmental problem of all time.

The only real chance in fight against climate change is the strong development of renewable energy sector, because this would mean less need for fossil fuels, and less fossil fuel burning would mean less greenhouse gas emissions, most notably CO2 emissions.

The share of renewable energy in global energy supply is increasing year after year but even despite this positive trend world will still continue to heavily depend on fossil fuels in years to come, meaning that the condition of our environment will likely further deteriorate and climate change impact will continue to strengthen.

Renewable energy needs time to become competitive in terms of costs and efficiency with fossil fuels, and this will certainly take some time. I’m just hoping that by the time this happens our environment, most notably our climate, won’t past the point of no return.
