I am glad to see you here. I hope you are well.
Today we are having a lesson on the topic “The Worlds Best Friend Is You”. What do you think
we shall speak about? (Pupils answer)
Yes, we shall speak about ecology, pollution, influence of a man on the environment. The
problem of our lesson is the global situation in ecology and what can we do with it. I hope you
are ready for the lesson.
II. Речевая зарядка.
Let's read the poem very attentively and try to understand what does it mean change to green.
Rub your eyes and look around,
Litter lying on the ground,
Bottles, cans and polythene-
Take the tip and change to green!
Forests going up in smoke,
Cities fit to make you choke,
Nowhere left to be thats clean-
Take a breath and change to green!
Animals and plants have died,
People starve to feed our pride,
For the life that might have been
Take a stand and change to green!
Theres so much that isnt right,
It could get you well uptight,
So make a start and change the scene-
The lights are flashing change to green!
P. I think the words change to green mean that the man can become better if he or she changes
his or her point of view on the nature.
P. To my mind change to green means to love not only nature but everything that is around us
and try to do the best to solve all environmental problems.
P. I think sometimes people dont pay attention to the damages and destructions that theyve
done.

VI. Проверка навыков аудирования.
Please, now listen to the text “Environmental Protection”; look at the sentences in the tests on
your desks but first pay attention to the words on the blackboard. Repeat them after me. I dont
ask you questions about the text, here is a little test complete the sentences using the right
word, and well see how you understand the text.
ENVIRONMENTAL PROTECTION.
The poisoning of the worlds land, air and water is one of the most important problems of
our civilization. The seas are in danger. Many companies dump chemical and nuclear waste into
water. The Mediterranean is already nearly dead; the North Sea is following. The Aral Sea is on
the brink of extinction. Half of the lakes in the world are polluted. If nothing is done about it, one
day nothing will be able to live in the seas.
Air pollution is also a very serious problem. Because many factories release sulfates into
the air. When the sulfates mix with the clouds, acid rains fall and harm all living creatures. In
Cairo just to breathe the air is like smoking two packs of cigarettes a day. Mexico City and 600
cities of Russia have dirty air. This causes different diseases. Because of different kinds of
pollution every ten minutes one kind of animal, plant or insect dies out forever.
People begin to realize that environmental problems are our problem. These are a lot of
international green organizations that take care of the environment and “Green Peace” is one of
the most active. Many governments are waking up and making strict laws against pollution.
Scientists are trying to make factories and plants cleaner. In many countries there are big plans to
clean up the water. And every person must do his best to help our planet survive.
TEST. You are to complete the sentences using the right word. Write down only the word.
1. Environmental protection is an ________ problem. (easy, important, pleasant)
2. Factories pour a lot of _______ into air & water. (a shortage, waste, pollution)

VI. Развитие навыков монологической речи. Работа в группах по три человека.
Now its high time to discuss and solve some ecological problems, the main topic is
“Environment”. We’ve divided into groups of three, thats why you are sitting in such a way.
You are to tell us the main points of the given topic. I give you 4-5 minutes. At the end well
make conclusions. Our topics are:
“Water pollution”, “Air Pollution”, “The Ozone Hole” (озоновая дыра), “The Greenhouse
Effect (парниковый эффект), “Acid Rains” (кислотные дожди). /Темы заранее давались
с целью поисковой работы/.
Please, stop discussing. One by one report your topic and make the conclusion, announce it.
P1. “Water Pollution” – We need to save our water, to keep it clean and healthy so people, plants
and animals will always have something to drink. And so fish and other creatures will have a
place to live.
P2. “Acid Rain” – Its very important for us to stop making acid rain. One good way to do that is
to drive our cars less. Another good way is to save energy. The less energy we use, the less coal
those power plants will have to burn.
P3. “Air Pollution” – Its very important for us to clean up the air we all breathe. Everyone can
help keep our air clean and safe. Its even fun! You can plant a tree, ride your bike, and even
write a letter to a newspaper.
P4. “Greenhouse Effect” – Everybody can help stop the greenhouse effect by using less energy,
protecting and planting tress, and by recycling so factories dont need to work as hard making
things.
P5. “The Ozone Hole” – Scientists are very concerned about the ozone layer, because a lot of it
has gone away in just a few years. So its very important that we learn to do something about it.
We can all help to stop the ozone layer from disappearing!
Thank you, well done, you are so clever I am proud of you.
