Good morning! I’m glad to see! I hope you’re fine and ready to take an active part in the lesson

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.
