I. Начало урока. Вступительное слово учителя
Good morning. Today we are going to continue speaking about the Earth's ecological
problems and the ways out of the situations. We’ll discuss what we can do to save the
Earth. That's why we need to revise our new words.
II. a)Фонетическая зарядка:
Read the transcription of the words and match them with the word they mean.

protection [prə'tekʃ(ə)n] destroy [dɪ'strɔɪ]

3. All of us know that we live on the Earth. But what do we know about it?
P1: The Earth is the 5
th
largest of 8 main planets in the solar system.
P2: It's the 3
d
planet from the Sun. The Sun is just one of many stars in the Milky Way
Galaxy.
P3: The Earth looks blue from space because 70% - nearly 3 quarters is covered with
water. There are four oceans on the Earth: the Pacific, the Atlantic, the Indian, the Artic.
P4: The Oceans contain 97% of all the water on the Earth.
4. Stand up, hold the hands of your partners, stretch your arms as wide as you can. Now
imagine that you are trying to reach from pole to pole. Do you know what the distance is
from pole to pole? It is more than 15.000 kilometres. They say it would take 12, 5 million
people holding hands to stretch from pole to pole. It's rather impressive, isn't it?
For thousands of years the Earth has given support to all forms of life human beings,
animals, birds, fishes, insects and plants. Many years ago our planet was very beautiful,
without any environmental problems.
And now our great, beautiful planet is in danger.
- What must people protect the Earth from?
-
What kinds of pollution do you know?
-
What must we do to protect the environment?

III. Экологическая обстановка в мире.
P1. I want to tell you about water pollution. The situation is really gloomy and
sometimes even hopeless. Rivers, lakes, seas, oceans cover more than 70% of our planet.
Scientists say “man will die if oceans die”. Over 5 million tons of oil products pollute the
ocean each year. About 2 million tons of these products come from cars. First the oil
products go into atmosphere. From the atmosphere they go into oceans. A ship wrecked
tankers spill a lot of oil into the ocean. In addition big rivers carry into the ocean a lot of
waste from industry and agriculture. Pollution means death to oceans. It kills fish, plants,
birds. Experts believe life in oceans will be destroyed within 25 years.
P2. I want to tell you about industrial pollution.The industry affects the nature greatly.
For example more than 30 years ago a pulp-and-paper factory was built on the shore of
lake Baikal. As a result, because of the water pollution, more than 50% of the world’s
purest water has been ruined. The whole ecological system of lake has changed greatly.
Some organisms that can be found only in the lake Baikal are disappearing; trees are
dying from the dust and gas blow-outs of the factory.
P3. Well, we see that water which is necessary for our life is polluted awfully. As for me,
I want to focus to another problem - the problem of air pollution. Nobody and nothing
on the Earth could live without air. People pollute the air all over the world. A great
number of trees growing on the planet produce oxygen and clean the air. But vast forests
are cut and burn in fire. Their disappearance upset the oxygen balance.
Видеосюжет о загрязнениях.
Р4. Besides, the ozone layer in the atmosphere protects the Earth from the dangerous
ultraviolet rays of the sun. It’s like a kind of a roof. But now, because of the air pollution,
the ozone layer is destroyed. The dangerous rays get through the atmosphere, causing
different diseases.
In addition awful harm is caused to our home by nuclear tests of atom bombs, accidents
on the atomic power stations, for example, Chernobyl tragedy in 1986. About 18% of the
territory of Byelorussia was polluted with radioactive substances.

VIII Заключение: Today we have spoken about some of the world’s most serious
environmental problems. Pollution is very dangerous for people, wildlife and the
environment. It’s no good pretending the ecological problems don’t exist- they do!
What’s more, they are getting worse all the time! And, dear children, it’s you who must
solve these problems!
