Read the following passage and choose the best answers to the questions. Conservation conflicts arise when natural-resource shortages develop in the face of steadily increasing demands from a growing human population. Controversy frequently surrounds how a resource should be used, or allocated, and for whom. For example, a river may supply water for agricultural irrigation, habitat for fish, and water-generated electricity for a factory. Farmers, fishers, and industry leader vie for unrestricted access to this river, but such freedom could destroy the resource, and conservation methods are necessary to protect the river for future use. Conflicts worsen when a natural resource crosses political boundaries. For example, the headwaters, or source, of a major river may be located in a different country than the country through which the river flows. There is no guarantee that the river source will be protected to accommodate resource needs downstream. In addition, the way in which one natural resource is managed has a direct effect upon other natural resources. Cutting down a forest near a river, for instance, increases erosion, the wearing away of topsoil, and can lead to flooding. Eroded soil and silt cloud the river and adversely affect many organisms such as fish and important aquatic plants that require clean, clear freshwater for survival. 26. What does supply in line 3 mean? A. cover B. provide C. make up for D. compensate for 27. Which word in the reading means living or growing in, or relating to water ? A. agriculture B. major C. fresh D. aquatic 28. When do conflicts get worse ? A. when natural-resource shortages increase in the features of gradually increasing demands from a rising human population. B. when a natural resource crosses political borders C. when freedom could destroy the resource. D. when eroded soil and silt cloud affect many organisms. 29. Which sentence below is NOT correct? A. Argument often surrounds how a resource should be used, or allocated, and for whom. B. A river may provide water for agricultural irrigation, habitat for fish, and water-generated electricity for a factory C. Conservation methods are incidental to care for the river for future use. D. Farmers, fishers and industry leaders vie for open access to this river. 30. What is the passage above mainly about? A. Conservation conflicts B. Agricultural irrigation C. The headwaters of a major river D. Natural-resource shortages VI. Rewrite the following sentences with the given words. 31. It wasnt Tom in the mall yesterday because he was in the hospital.
