They are home to about 80% of the world’s land animals and plants. Trees in forests provide shelter for animals. Birds build nests in the branches, and squirrels live in the holes of the trees. Many plants grow under the trees, getting enough shade. Forests also help control the climate. They absorb rainwater and prevent floods. The roots of the trees hold the soil together, stopping it from being washed away. However, forests are in danger. People cut down millions of trees every year for wood and to make space for farms and cities. This is called deforestation. Deforestation destroys the homes of wild animals and increases the risk of floods. We must protect forests. We can plant more trees, use less paper and support laws against deforestation. 26. Why are forests called the “lungs of the Earth”? A. Because they look like lungs.B. Because they produce oxygen and absorb carbon dioxide. C. Because they are important for breathing. D. Because they are full of air. 27. What percentage of the world’s land animals and plants live in forests? A. About 20%. B. About 50%. C. About 80%. D. About 100%. 28. How do forests help control the climate? A. By producing oxygen. B. By absorbing rainwater and preventing floods. C. By providing shelter for animals. D. By growing many plants. 29. What is deforestation? A. Planting more trees. B. Cutting down millions of trees for wood and space. C. Protecting forests. D. Making laws against cutting trees. 30. What can we do to protect forests? A. Cut down more trees. B. Use more paper. C. Plant more trees and support laws against deforestation. D. Build more farms and cities in forests. B Rivers: Lifeblood of the Earth Rivers are like the lifeblood of the Earth. They provide water for drinking, washing and farming. They are also home to many kinds of fish and other water animals. Many cities are built near rivers because water is essential for people. Rivers also help transport goods. Boats can carry heavy things along the rivers, which is cheaper than using trucks. However, rivers are facing many problems. Pollution from factories is a big issue. Chemicals and waste from factories are poured into rivers, making the water dirty. This kills fish and other animals in the rivers. Farmers also use too much fertilizer, which runs into the rivers and causes pollution. Rubbish from people is another problem—plastic bags and bottles float in the rivers, harming the environment. We need to protect rivers. Factories should clean their waste before pouring it into rivers. Farmers should use less fertilizer. And people should stop throwing rubbish into rivers. 31. Why are rivers important? A. They provide water for people and animals. B. They are good places to swim. C. They make the Earth look beautiful. D. They are full of fish. 32. Why are many cities built near rivers? A. Because rivers are beautiful. B. Because water is essential for people. C. Because rivers can transport goods. D. Because there are many fish in rivers. 33. What is a big problem for rivers? A. Too much water. B. Not enough fish. C. Pollution from factories, farms and people. D. Rivers are too narrow. 34. How do factories pollute rivers? A. By pouring chemicals and waste into rivers. B. By building near rivers. C. By using too much water. D. By fishing in rivers. 35. What can we do to protect rivers? A. Pour waste into rivers. B. Use more fertilizer. C. Throw rubbish into rivers. D. Factories clean waste, farmers use less fertilizer and people stop throwing rubbish. C Mountains: Beautiful and Important Mountains are not only beautiful but also very important. They are home to many plants and animals that can’t live in other places. Mountains affect the weather. When wind blows against a mountain, it has to rise. As the air rises, it cools and forms clouds, which then bring rain. This is why there is often more rain on one side of a mountain. Mountains also provide water. Snow and ice on the mountains melt to form rivers and lakes. These provide water for people and animals in the surrounding areas. People enjoy visiting mountains for hiking, skiing and other activities. But tourism can also bring problems. Too many people may leave rubbish, damage plants and disturb animals. We should protect mountains by following the rules of the mountains, taking rubbish away and not damaging the environment. 36. Why are mountains important? A. They are beautiful. B. They are home to special plants and animals and affect weather and provide water. C. They are good for skiing. D. They are easy to climb. 37. How do mountains affect the weather? A. By making the air hot. B. By stopping the wind. C. By causing clouds and rain when wind rises. D. By making the air dry. 38. What do mountains provide? A. Food. B. Water from melting snow and ice. C. Shelter for people. D. All of the above. 39. What problems can tourism bring to mountains? A. Rubbish, damage to plants and disturbance to animals. B. More rain. C. More snow. D.
