WHAT CAN YOU SEE IN THIS PICTURE ?THERE IS A FOREST FIRE. What is he doing?He is hunting a rare animal. What does this picture say about? The flood damaged the bridge. Task 1: Find the position of these words and guess their meanings. eliminate circulation run-off hydroelectric  A.The loss of forest in destroying the earth’s plant and animals variety.Scientists say about 5,000 species of plants and anima are eliminated each year .This is especially worrying as many of those plants and animals could be used as medicines against cancer ,AIDS,heart disease and many other sicknesses .We may never know the true cost of this destruction. B Man and most animals need a constant supply of water to live.Farmers need water of their crops.Hydroelectric dams hold back needed water and provide power for homes and industries .Trees , grasses ,and other plant life play an important part in the natural circulation of water ,and thus help conserve it .Without plants ,most water would run off as soon as it falls, taking away valuable soil. Rapid run-off would cause frequent floods and leave little water during dry seasons. C These days it is impossible to open a newspaper without reading about the damage we are doing to the environment .The earth is being threatened and the future looks bad.What can each of us do? We cannot clean up our polluted rivers and seas overnight.Nor can we stop the disappearance of plants and animals .But we can stop worsening the problem while scientist search for answers ,and laws are passed in nature’s defense. hydroelectric run-off circulation eliminate  1.eliminate  2.circulation  3.run-off  4.hydroelectric  a.the movement of something around a closed system  b.concerning or producing electricity by the power of falling water  c.remove or get rid of completely  d.liquid which flows off or from (something) Task 2:Look for wrong information and correct it 1. Each year about fifty hundred species of plants and animals are eliminated. 2. Many kinds of plants could be used to treat various dangerous diseases. 3. Water can be held on land by vegetation 4. Man is constantly doing harm to the environment 5. Plants may cause floods and erosion. 6. We can do nothing to save the earth.
