  • 3. Similarities and Differences Find similarities and differences between: (the Aral Sea) and (the Dead Sea). * salt levels / shrink * rivers feed each one
  • 4. Read the given questions before each paragraph. Then read it silently to give correct answers. ---------------------------------------------------------------------------Paragraph 1: 1. Where’s the Aral Sea? 2. What changes can bring a terrible water disaster? Lakes are going through bad times worldwide.Modern farming is taking water from the rivers that feed lakes. Farm chemicals are also getting into the water and polluting it. These changes can bring terrible disaster. The Aral Sea, in the old Soviet Union ,is on such disaster.
  • 5. Paragraph 2 1. What were the people’s main jobs in the Aral Sea area? 2. What was the sudden change in the Aral Sea? Why? 3. T /F Before 1960s, the Aral Sea used to be one of the largest freshwater lakes in the world. The Aral Sea was the world’s fourth-largest freshwater lake until the 1960s. People lived well from the successful fishing and local farming industries. This would have continued if the Moscow Government had not introduced a huge and sudden change. The planners suddenly decided to turn the region into a major cotton product The government needed money, and cotton sells well internationally .
  • 6. Paragraph 3: 1. ‘Cotton is thirsty’, that means -------------------2. What caused pollution to the whole environment in the region? 3. ‘These’ L.5 refers to -------------------4. Find synonyms for: required / quantities / complete However, cotton is thirsty, and the region is dry. Water was needed from the two large rivers that fed the Aral Sea. Soon, more and more water was being taken from them for irrigation. Increasing amounts of farm chemicals were also being used. These started getting into the rivers, the lake and groundwater and polluting the whole environment.
  • 7. Paragraph 4: 1. Why is cotton called ‘the white gold’? 2. T/ F The planners thought about the effect and saw the dangers on the Aral Sea. 3. Find the antonyms of: safety / continued / led The planners should have  thought about the effects on the Aral Sea, but they cared only about the white gold . If they had thought, they would have seen the dangers, and at that time, they could have stopped. However, they did not, and one of the world’s greatest environmental disasters followed.
  • 8. Paragraph 5: 1. What two things have caused the Aral Sea to shrink and become very salty? 2. Why did 60,000 fishermen lose their jobs? 3. T/F The Aral Sea is 40% of its old area. 4. Find synonyms of: more than / locate / several 5. Complete: --------------------, so the fish and the fishing industry died. By 1983, all the river water was being taken. The rivers were dry, and the Aral Sea was also evaporating. Soon, the water was too salty for anything to live. The fish died, and the fishing industry, too. Over 60,000 fishermen lost their jobs. The lake was also shrinking. Today, it is two-fifths of its old area and just 15% of its original volume. Hundreds of rusty fishing boats lie on the old seabed, many kilometres from water.
  • 9. Paragraph 6: 1. What are the effects of the Aral Sea changes on human health? 2. Find the opposites of: weak / causes 3. ‘This’ L4 refers to -------------- There have been other disastrous effects . Strong winds blow salty, polluted dust from the seabed across the land. This and the polluted water are causing cancer and other killer diseases. Many children are also being born with physical defects.
  • 10. Paragraph 7: 1. Complete: The irrigation water contains salts, so ----------------------2. ‘The land is dead’ L. means that ----------------------3. ‘these’ L.3 refers to ----------4. T/ F The cotton is dying because there is a shortage of irrigation water. Now the cotton itself is dying. The irrigation water brings salts and these remain in the ground. The salts cover the plants’ roots and kill them. The land is dead. The planners could and should have foreseen what would happen. If they had, they might have thrown away their plans.
