　　第一篇

　　In the United States, the need to protect plant and animal species has become a highly controversial and sharply political issue since the passage of the Endangered Species Act in 1973. The act, designed to protect species’ living areas, and policies that preserve land and forests compete with economic interests. In the 1990’s, for example, the woodcutters in the Western United States were challenged legally in their attempt to cut trees for timber in the Cascade Mountains. The challenge was mounted to protect the endangered spotted owl (猫头鹰), whose remaining population occupies these forests and requires the intact, ancient forest for survival. The problematic situation set the interests of environmentalists against those of corporations and of individuals who stood to lose jobs. After months of debate and legal battles, the fate of the woodcutters-and the owls-was still undecided in mid-1992.

　　Similar tensions exist between the developed and the developing nations. Many people in industrialized nations, for example, believe that developing nations in tropical regions should do more to protect their rain forests and other natural areas. But the developing countries may be impoverished (使穷困), with populations growing so rapidly that using the land is a means to temporarily avoid worsening poverty and starvation.

　　Many of the changes to Earth that concern scientists have the potential to rob the planet of its biological richness. The destruction of Earth’s ozone layer (臭氧层), for example, could contribute to the general process of impoverishment by allowing ultra-violet rays to harm plants and animals. And global warming could wipe out species unable to quickly adapt to changing climates. Clearly, protecting will come only through coordinated international efforts to control human population, stabilize the composition of the atmosphere, and preserve intact Earth’s complex web life.

　　36. Why does the author say that the protection of endangered species is a highly controversial issue?

　　A) Because people can’t agree as to what species to protect.

　　B) Because it is difficult to find an effective way to protect such species.

　　C) Because it affects the interests of certain groups of people.

　　D) Because it is a major problem involving a series of legal procedures.

　　37. According to the passage, the preservation of rain forests ________.

　　A) may hamper a developing country in its fight against poverty

　　B) benefits developed countries rather than developing countries

　　C) should take priority over the control of human population

　　D) will help improve the living conditions in developing countries

　　38. According to the passage, cutting tress to grow more food ________.

　　A) will widen the gap between the developed and the developing countries

　　B) is but a short-term relief to the food problem

　　C) can hardly alleviate the shortage of food

　　D) proves to be an effective way out for impoverished nations

　　39. Among “humanity’s current problems” (Line 6, Para. 3), the chief concern of the scientists is ________.

　　A) the impoverishment of developing countries

　　B) the explosion of the human population

　　C) the reduction of biological diversity

　　D) the effect of global warming

　　40. The author’s purpose in writing this passage is ________.

　　A) to describe the difficulties in solving humanity’s current problems

　　B) to present the different views on humanity’s current problems

　　C) to analyze the contradiction between countries in dealing with humanity’s current problems

　　D) to point out that humanity’s current problems can only be solved through the cooperation of nations

　　第二篇

　　Many Americans harbour a grossly distorted and exaggerated view of most of the risks surrounding food. Fergus Clydesdale, head of the department of food science and nutrition at the University of Massachusetts-Amherst, says bluntly that if the dangers from bacterially contaminated chicken were as great as some people believe, “the streets would be littered with people lying here and there.”

　　Though the public increasingly demands no-risk food, there is no such thing. Bruce Ames, chairman of the biochemistry department at the University of California, Berkeley, points out that up to 10% of a plant’s weight is made up of natural pesticides (杀虫剂). Says he: “Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare.” And many naturally produced chemicals, though occurring in tiny amounts, prove in laboratory tests to be strong carcinogens-a substance which can cause cancer. Mushrooms (磨菇) might be banned if they were judged by the same standards that apply to food additives (添加剂). Declares Christina Stark, a nutritionist at Cornell University: “We’ve got fat worse natural chemicals in the food supply than anything man-made.”

　　Yet the issues are not that simple. While Americans have no reason to be terrified to sit down at the dinner table, they have every reason to demand significant improvements in food and water safety. They unconsciously and unwillingly take in too much of too many dangerous chemicals. If food already contains natural carcinogens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small amounts of contaminants generally found in food and water, at least a few individuals will probably get cancer one day be cause of what they eat and drink.

　　To make good food and water supplies even better, the Government needs to tighten its regulatory standards, stiffen its inspection program and strengthen its enforcement policies. The food industry should modify some long-accepted practices or turn to less hazardous alternatives. Perhaps most important, consumers will have to do a better job of learning how to handle and cook food properly. The problems that need to be tackled exist all along the food-supply chain, from fields to processing plants to kitchens.

　　21. What does the author think of the Americans’ view of their food?

　　A) They overstate the government’s interference with the food industry.

　　B) They are overoptimistic about the safety of their food.

　　C) They overestimate the hazards of their food.

　　D) They overlook the risks of the food they eat.

　　22. The author considers it impossible to obtain no-risk food because ________.

　　A) no food is free from pollution in the environment

　　B) pesticides are widely used in agriculture

　　C) many vegetables contain dangerous natural chemicals

　　D) almost all foods have additives

　　23. By saying “they employ chemical warfare” (Line 4, Para. 2), Bruce Ames means “________”.

　　A) plants produce certain chemicals to combat pests and diseases

　　B) plants absorb useful chemicals to promote their growth

　　C) farmers use man-made chemicals to dissolve the natural chemicals in plants

　　D) farmers use chemicals to protect plants against pests and diseases

　　24. The reduction of the possible hazards in food ultimately depends on ________.

　　A) the government

　　B) the consumer

　　C) the processor

　　D) the grower

　　25. What is the message the author wants to convey in the passage?

　　A) Eating and drinking have become more hazardous than before.

　　B) Immediate measures must be taken to improve food production and processing.

　　C) Health food is not a dream in modern society.

　　D) There is reason for caution but no cause for alarm with regard to food consumption.
