VII. Совершенствование навыков устной речи по теме

a) Beauty Must Be Protected (2 min)

6. An Apple As the World.

· Look at the apple, use your imagination and say what the apple could represent.

· Cut the apple into quarters: ѕ of the Earth is water, ј is land.

· 1/4:2=1/2 of land is habitable; Ѕ of land is deserts, mountains, forests, ice and snow. People can`t live there.

· Habitable land: 4=1/4 of the habitable land, or 1/32 of the Earth is where all food comes from.

Question: What would happen if this part of the world were damaged and destroyed? (pupil eats this piece of apple)

Conclusion: We must protect our planet.

b) декламирование стихотворения “Change to green”(2 min)

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!

7. QUIZ: “How Green Are You?”

Here is a quiz to see how green you are and how well informed you are about the environment. As we have already known Green here means environmentally friendly. Read the questions and choose the answer you agree most with. Are your answers mostly a, b or c? See the key to find out how green you are. It will be your homework.

c) Устные высказывания (обобщение полученной информации) (7 min)

8. T: Here are some environmental problems: water pollution, ozone holes, disposing of the garbage. Take cards with words and phrases, please. Look through the list of words. I'll give you about a minute to make up a short topic, these words will help you to do it.

Words on the topics:

1. Endangered species

endangered species to disappear to kill animals to destroys their habitats to be in danger	plant badly damaged be able to recover to be cut down to help to control the world's weather to produce the oxygen

(Suggested answer)

Many endangered species -- fish, reptiles, insects, birds, mammals -- may disappear. The reason is that Man kills animals and destroys their habitats. It is not just animals that are in danger. So are plants. A lot of forests are so badly damaged that they will hardly be able to recover. When the trees are cut down, the forest becomes a desert. The huge forests help to control the world's weather and to produce much of the oxygen in the air.

2. the greenhouse effect

sunlight

heat

to warm the atmosphere

to go back into space

to become warmer

winter and summer temperatures

to produce

carbon dioxide

to work like glass in a greenhouse

to get in/to get out

(Suggested answer)

Have you ever heard about the greenhouse effect? It works like this: sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat goes back into space. Nowadays the air surrounding the earth has become much warmer because the heat can't go back into space. That's why winter and summer temperatures in many places have become higher.

During the last 100 years people have produced a lot of carbon dioxide. This gas in the atmosphere works like glass in a greenhouse. It lets heat get in, but it doesn't let much heat get out. So the atmosphere becomes warmer.

3. Water pollution:

ocean, sea, rivers and lakes

to be used as a dump

The Pacific Ocean

To suffer

nuclear pollution

to test nuclear weapons

industrial and nuclear waste

to poison

"nuclear-poisoned" fish

enough oxygen

to leave their habitats

can die

to happen

factories and plants

to pour into

(Suggested answer)

There is no ocean or sea which is not used as a dump. The Pacific Ocean, especially, has suffered from nuclear pollution because the French Government tests nuclear weapons there. Many seas are used for dumping industrial and nuclear waste. This poisons and kills fish and sea animals. "Nuclear-poisoned" fish can be eaten by people.

Many rivers and lakes are poisoned too. Fish and reptiles can't live in them. There is not enough oxygen in the water. In such places all the birds leave their habitats and many plants die. If people drink this water they can die too. It happens so because factories and plants produce a lot of waste and pour it into rivers. So they poison the water.

4. the ozone layer:

to spend too much time

direct sunlight

ultraviolet radiation

to cause skin cancer

to protect

holes in the ozone layer

to get to the earth

scientist

the result of

air pollution

(Suggested answer)

More and more often people are told not to spend too much time in direct sunlight, because ultraviolet radiation from the sun can cause skin cancer. Normally the ozone layer in the atmosphere protects us from such radiation, but if there are holes in the ozone layer ultraviolet radiation can get to the earth. Many scientists think that these holes are the result of air pollution.

5. air pollution:

to release sulfates

mix with the clouds

acid rains

to harm

creature

nuclear power stations

to go wrong

to cause nuclear pollution

nuclear pollution

cannot be seen

can be terrible.

to make air clean

filter

cars and buses.

(Suggested answer)

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. Nuclear power stations can go wrong and cause nuclear pollution. Nuclear pollution cannot be seen but its effects can be terrible.

To make air clean again we need good filters at nuclear power stations, at factories and plants and also in cars and buses.

6. Conclusions

clean air and clean water

necessary for

health

to survive

to solve these problems

to understand

environment

the whole earth

all over the world

speak about ecology.

(Suggested answer)

Both clean air and clean water are necessary for our health. If people want to survive they must solve these problems quickly. Man is beginning to understand that his environment is not just his own town or country, but the whole earth. That's why people all over the world think and speak so much about ecology.

T: Thank you. Well done. To sum up our work let's find out what we Should Do and what we Shouldn't Do. Come here one by one, take any shit of paper you want, read it and say what we should do.
