(1 слайд)
T: Look at the picture, please. Can you name the topic of our lesson.

P: The environmental problems.

T: You are right. Today we are going to talk about the environmental problems on our planate.

(2,3 слайд)
About two hundred years ago people lived in harmony with nature, because industry was not much developed. But progress does not come to a standstill and the contradictions between man and nature are dramatic.

3) Фонетическая разминка. 

T: Let's begin with “the snowball” to revise the words you know. One person names the word, the other repeats his word and adds his own. For example: environment; environment, dump; environment, dump, pollution and so on.

II Основной этап

1) Увеличение объема используемых лексических единиц. Развитие навыков чтения, говорения, письма.

T: You can see card №1 on your desks. Take it, please.

 Read the text and try to understand it. Be ready to answer my questions and do some tasks. You have 5 minutes.

Карточка №1:

                                We need our planet cleaner and healthier.

The Earth is our home, but much of it is dirty and dying.

By the year 2030, scientists report that 25% of all animals, birds, fish and insects may be extinct.

Every year man cuts down more trees to provide paper, wood, medicines, mineral fuel. But it's not only trees and forests which are disappearing. Animals, insects and flowers are destroyed, too. Is there any solution? People should protect certain areas and plant new forests.

Cars and factories pollute air, water and land. They can also be dangerous for people, wildlife and environment.

One of Europe's and North America's most serious pollution problems is "acid rain". This happens when factories send gases and chemicals into the air. There they mix, and the mixture is carried for hundreds of miles by the wind and finally falls back to earth. This "acid rain" kills fish and trees. It slowly destroys everything. Industrial countries should control their level of pollution and try to reduce the acid rain effect.

At the moment, 94% of the world's energy comes from oil, gas and coal. But these "fossil fuels" won't last forever. There's only enough oil and gas for the next 50 years. Coal will last longer - perhaps about 300 years. And then? Well, one answer is nuclear energy. But today, after Chernobyl, many people think it's too dangerous. There are four solutions.

They all use natural energy in the environment: wind energy, wave energy (from the sea), and geothermal energy (from "hot" rocks under the ground). It's clean and natural, but there is another problem: they all rather expensive.

Today, many scientists and world leaders realize that the Earth is in danger. Either we stop killing the Earth or we kill ourselves. We need a cleaner, healthier planet.
