Цілі: вдосконалювати навички вживання нових лексичних одиниць і навички читання, аудіювання й усного мовлення; розвивати мовленнєву реакцію й пізнавальні інтереси учнів; виховувати зацікавленість у розширенні своїх знань, любов до природи.
Answer the questions.
1) What everyday objects can we recycle?
2) What causes air pollution and acid rain?
3) Which of the world’s seas are the most polluted?
4) What is happening to the world’s rainforests?
5) What destroys the ozone layer?
6) What is happening to the world’s climate?
Friends of the Earth is fighting on these issues:
We can still do more to recycle glass, paper, cans and plastic.
Pollution from factories and cars poisons the air we breathe and causes acid rain, which kills our trees.
Many of our seas, like the North Sea and the Mediterranean, are full of chemicals and sewage.
Saving the rainforests
In Brazil’s rainforests an area roughly the size of England and Wales is destroyed every year.
The ozone layer
Chemicals like the CFCs (chlorofluorocarbons) found in fridges, some aerosols, fast food packaging are damaging the ozone layer.
The greenhouse effect
The world’s temperature is going up and the climate is changing.
Listen to the text and say if the statements are True or
Tropical rainforests grow around the earth’s equator (South America, Central America, Africa, Southeast Asia and Australia), and cover 7% of the earth’s surface. The biggest tropical rainforest is the Amazon rainforest in South America. Rainforests are important for the earth. They give the earth oxygen, and are a home for half of the world’s animals and plants. But the rainforests are in danger – each second we destroy a part of the rainforest that is the same size as a football field.
The Amazon rainforest is the largest in the world. It is 3.3 million sq km and covers 40% of South America. It is part of 8 countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana and Suriname.
Tropical rainforests are wet and warm. They get more than 2 metres of rain each year, and temperatures are usually between 24-27° C. Tropical rainforests have lots of trees and plants, they are divided into four different layers. Each layer has a different environment with different plants and animals. Half the world’s animals live in rainforests – bats, monkeys, snakes, anteaters, jaguars – and 80 % of the world’s species of insects (40,000 different species).
Many of the plants in the rainforests are useful to us as food or oils (banana, palms). Also, 25 % of modern medicines originally came from the rainforests.
Rainforests provide us with food and medicine. They are also the “lungs of the Earth”. They turn carbon dioxide into clean oxygen, and they cool our planet.
But rainforests are in danger. About 2,000 trees a minute are cut down for wood or to find minerals, or to clear land to grow food or to make room for housing.
We can help to protect the rainforests. We can buy things that are not made from rainforest wood, we can buy local products, and we can recycle materials.
True or False
1) Tropical rainforests are found all over the Earth.
2) The Amazon is the largest rainforest.
3) It rains a lot and it’s often cold.
4) There are different layers of plants and trees.
5) Tropical rainforests are not good homes for animals.
6) Rainforests give us only food and oils.
7) Rainforests are in danger because people cut down them.
8) We can’t do anything to protect the rainforests.
Look at the diagram and say why wildlife on the planet is in danger. What can be done to save wildlife?
