You'll also develop your grammar skills in making conditional sentences to express future actions. At the end of the lesson you'll have to be able to talk using the new vocabulary on this theme. Good luck!

- making water, air, atmosphere dirty and dangerous for people and animals to live in (pollution);
- a place where rubbish is left (a dump);

- угрожать жизни людей (to endanger people's lives);
- "тепличный /парниковый эффект" (the greenhouse effect);

c) Учебный разговор: Teacher – P1, P2, P3.
Teacher: We live on the planet Earth. Nowadays it is in great danger because it has been suffering from many environmental problems. The most serious of them are mentioned here. Will you name them?
P1 - air pollution;
P2 - water pollution;
P3 - nuclear pollution;
P4 - rubbish problem;
P5 - destruction of wildlife;
Р6 - "the greenhouse effect";
P7 - ozone holes.
Teacher: Answer my questions, please. Разминка перед обучением устной речи.
- Where does air pollution mostly come from? (cars, buses, plants and factories)
- What can appear as the result of air pollution? (holes in the ozone layer)
- Why are holes in the ozone layer dangerous? (ultraviolet radiation from the sun
can get to the earth and cause skin cancer) - What shouldn’t we do not to get skin cancer? (not to be in direct sunlight for long)
What makes the sea waters dangerous? (testing of nuclear weapon, dumping
industrial and nuclear waste into rivers, seas, oceans) - Why is it dangerous to dump industrial waste in the sea? (this poisons and kills fish and sea animals)
- Why are nuclear power stations dangerous? (they can go wrong and cause
nuclear pollution) - Why have some species of animals become endangered? (the Man kills animals and destroys their habitats)
- Why can "the greenhouse effect" be dangerous for the planet? How does it work? (the air surrounding the earth has become warmer because the heat which sunlight gives us can't go back into space, as a result of it winter and summer temperatures have become higher)
- What do you think people can do first to start to save our planet?
- What has already been done in the world to save our planet from the ecological disaster? (International organizations, filters at factories and plants, in cars and buses, the Red Book, The Greenpeace).
- Работа по схеме T – P1, P2, P3.
IV. Обучение устной речи.
1) Конкурс плакатов.
Teacher: Much attention is paid to the environmental problems at our school. The pupils would like to keep correspondence with international organization, which works to protect our environment, they take part in different meetings and conferences devoted to this problem and after all they will take part in different drawing contests and try to attract our attention to this problem by their posters. Here are some of them. Choose the poster which you like most of all and try to explain what ecological problem it presents.
2) Составление тематических надписей (на футболках) по теме “Защитим нашу планету”.
Teacher: Now I want you to take part in the similar contest. Imagine that the Greenpeace organization asked you to design T-shirts telling people about ecological problems of the day. Work in two or three groups and design a T-shirt on sheets of paper or cardboard.
V. Физкультминутка.
VI. Обучение чтению.
Teacher: Put the pieces of these mixed up stories right and read the texts about extinct animals. Give each story a title. Find a key sentence (a sentence expressing the main idea in each paragraph).
Text № l
Nowadays rainforests occupy a relatively small area. Quite a lot of people still don’t know what effect the destruction of the rain forest may have on the world climate. Tropical forests are very important for our planet because they are home to a great variety of plants, insects, birds and animals.
To conclude, if people want to be healthy and to live happily on Earth, they must preserve rainforests.
Tropical forests are called the “world’s largest pharmacy” because a lot of natural medicines have been discovered there. More than half of the world’s species of plants and animals are found in rainforests. They also offer the way of life to many people living in and around the forest. What is more, rainforests are lungs of our planet because they produce a significant amount of the world’s oxygen.
Text № 2
Dinosaurs lived on the Earth for over 140 million years. Then, suddenly, 65 million years ago, all the dinosaurs died, and most of the other animals and plants died along with them. Over 75 per cent of life on the Earth became extinct. For more than 150 years scientists have tried to find why.
Many of them think that a change in climate caused it. But what could cause a change in climate? Some scientists say that an asteroid fell on the earth 65 million years ago. A huge cloud of dust rose into the sky. There was no sunlight. Temperatures became very low, and without sunlight, plants died. The dinosaurs died from hunger and freezing.
This theory answers all the questions. Scientists are still asking questions and try to explain why so many plants and animals became extinct. It's one of the oldest mysteries in the world.
VII. Обучение аудированию.
a) Teacher: Listen to my reading and say why people need no less protection than animals do.
Ecology of Man.
No medicines prescribed by the doctors can help them. This problem becomes more and more serious with every passing day. The modern way of life when people have little physical activity, use cars instead of walking, watch TV for many hours and work on computers is turning them into legless creatures.
It may sound funny to you, but man needs protection and care as much as animals do. People's habitats - their homes towns and cities - must be kept ecologically clean. In the places where people drink poisoned water, eat bad food and breath polluted air they suffer from serious diseases and die earlier; their children are born weak.
b) Teacher: Think of 4 things Modern Man must do to survive. Then we'll compare your lists. Suggested answers:
to stop air and water pollution;
to keep waters in the rivers and lakes clean;
to stop nuclear tests;
to eat ecologically clean food;
to plant new forests and keep them clean;
to be physically active;
to spend more time out of towns.
VIII. Обучение грамматике.
Teacher: Make the following conditional sentences complete.
If people think more about ecology...
If people use filters at nuclear power stations...
If we don't dump waste into rivers...
If factories dump their waste in the rivers...
If people want to survive...
If people use nuclear weapons...
If people don’t cut trees…
IX. Обучение письму. Кроссворд.
Teacher: Write down the words concerning our theme beginning them with the following letters. Compose more words if possible.
D….(amage)
E………. (nvironment, endanger)
S……(urvive, safe, species)
T…(est)
R…….(adiation, ruin)
U………(ltraviolet)
C……(risis, creature)
T………(emperature, ton)
I………….(nternational)
O…. (zone)
N….. (uclear)
X. Домашнее задание. Объяснение.
Teacher: At home think over and write a letter to the Mayor of our city in support of citizens or drivers. Give convincing arguments. Try to use conditional sentences (12-15 sentences).
