Введение новой лексики.
Look at the screen, please. Our planet is amazingly beautiful.
My comments and pictures will help you to guess their meaning of new words.
What are we going to discuss today? Yes, you are right! The topic is: “Environment”
What is environment?
The word environment means simply what is around us (the air, water, and land around us).
Some people live in a town environment; for others, their environment is the countryside. But the air we breathe, the soil on which we stand and walk, the water we drink are all part of the environment.
Some kinds of human activities cause pollution (dirty air, water, land)
Some of their activities are destroying the environment (damaging it so badly that soon some parts of it will not exist).
Here are some of the problems:
The ozone layer: a layer of gases which stop harmful radiation from the sun reaching the earth; recent research shows that there is now a hole in some parts of the ozone layer.
Global warming: an increase in world temperature caused by an increase in carbon dioxide.
Acid rain: rain that contains dangerous chemicals; this is caused by smoke from factories.
Common causes of damage
smoke from factories
car exhaust fumes
dumping (throwing away) industrial waste in seas and rivers.
aerosol cans (usually called sprays). Some of these contain CFCs which can damage the ozone layer.
cutting down tropical rainforests. This increases carbon dioxide in the atmosphere.
How can we help?
Don’t throw away bottles, cans, packages. Take them to a bottle bank or a newspaper bank then they can be recycled (used again)
Plant more trees.
Don’t waste ( use badly) resources, e.g. water, gas. Try to save them.
Nowadays people understand how important it is to solve the environmental problems that endanger people’s lives.
These are our active words. Let’s try pronounce them correctly and translate.
