ХОД УРОКА
I. Оргмомент.
– Good
morning, my dear. Sit down, please. The theme of today’s lesson is
“Environmental Protection”. The problem of our lesson is the global
situation in ecology and what can we do with it. We are going to check your
home task at first, then listen to the unknown text and do a little test,
discuss and solve the problems of ecology and environmental protection, to
check your knowledge through the quiz again.
II. Речевая зарядка.
– Listen
to 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 that’s 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!
There’s so much that isn’t right,
It could get you well uptight,
So make a start and change the scene-
The lights are flashing – change to green!
PI. 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.
P2. 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.
– I’d like
to pay your attention to the words of Francis Thomson, an English poet, he
said, “One couldn’t pluck a flower without troubling a star.” These words
are the motto of our lesson. Do you agree with the author? Why does
technology owe an apology to ecology?
P. Yes, I do. I think
that technology owe an apology to ecology because sometimes people don’t
pay attention to the damages and destructions that they’ve done.
III. Проверка домашнего задания.
– At home
you read the text “Pollution Solutions” to the end and now I want to know
how well you understand it. The text is about pollution in the USA.
Here is an ecological quiz, where you should write whether these statements
are false or true. I give you only 4 minutes.

IV. 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 don’t ask you questions about the text,
here is a little test – complete the sentences using the right word, we’ll
see how you understand the text.
ENVIRONMENTAL PROTECTION.
The
poisoning of the world’s 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.

Работа в группах по три человека.
– Now it’s
high time to discuss and solve some ecological problems, the main topic is
“Environment”. We’ve divided into groups of three, that’s why you are
sitting in such a way. Two speakers will have a conversation about the
given topic, while the listener pays attention to their discussion. No one
is allowed to take notes. I give you 4-5 minutes. When everyone has quieted
down, the listener from each group become a reporter. He or she will tell
us the main points of their conversation. At the end we’ll make
conclusions. Our topics are:
“Water
pollution”, “Air Pollution”, “The Ozone Hole”, “The Greenhouse Effect”,
“Acid Rains”./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”
– Our mission . We need to save our water, to keep it clean and healthy so
people, plants and animals will always have some to drink. And so fish and
other creatures will have a place to live.
P2. “Acid Rain” – Our
mission. It’s 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” –
Our mission. It’s very important for us to “clean up our act”, and clean up
the air we all breathe. Everyone can help keep our air clean and safe. It’s
even fun! You can plant a tree, ride your bike, and even write a letter to
a newspaper.
P4. “Greenhouse
Effect” – Our mission. Everybody can help stop the greenhouse effect by
using less energy, protecting and planting tress, and by recycling – so
factories don’t need to work as hard making things.
P5. “The Ozone Hole” –
Our mission. Scientists are very concerned about the ozone layer, because a
lot of it has gone away in just a few years. So it’s 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.
VI.
Проверка навыков чтения с извлечением определенной информации.

understanding some particular points in the text. I was very surprised when
first found “The Declaration of Interdependence”. Now I’d like you to look
through this text. (4 minutes). Don’t translate the text, just find and
read the sentences corresponding to their Russian equivalents.
1.
Стабильность сообществ всех живых существ зависит от этого разнообразия.
2. Наш дом – планета Земля – ограничена…
3. Мы можем отрицать эти понятия, но мы не можем изменить их.
VII. Подведение итогов урока.

got marks and I think you are satisfied. The main problem of the lesson is
solved, you know how we can protect our environment and what we can do for
this. Be kind to nature and nature will help you.
