【简答题】
Britain almost more than any other country in the world must seriously face the problem of building upwards, that is to say, of accommodating a considerable proportion of its population in high blocks of flats. It is said that the English man objects to this type of existence, but if the case is such, he does in fact differ from the inhabitants of most countries of the world today. In the past our own blocks of flats have been associated with the lower-income groups and they have lacked the obvious provisions, such as central heating, constant hot water supply, electrically operated lifts from top to bottom, and so on, as well as such details, important notwithstanding ( 然而 ), as easy facilities for disposal of dust and rubbish and storage places for baby carriages in the ground floor, playgrounds for children on the top of the buildings, and drying grounds for washing. It is likely that the dispute regarding flats versus ( 对,对抗 ) individual houses will continue to rage on for a long time as far as Britain is concerned. And it is unfortunate that there should be hot feelings on both sides whenever this subject is raised. Those who oppose the building of flats base their case primarily on the assumption ( 设想 ) that everyone prefers an individual home and on the high cost per unit of accommodation. The latter ignores the higher cost of providing full services to a scattered community and the cost in both money and time of the journeys to work for the suburban resident. 31. We can infer from the passage that ________. A) English people, like most people in other countries, dislike living in flats B) people in most countries of the world today are not opposed to living in flats C) people in Britain are forced to move into high blocks of flats D) modern flats still fail to provide the necessary facilities for living ( B ) 32. What is said about blocks of flats built in the past in Britain ? A) They were mostly inhabited by people who did not earn much. B) They were usually not large enough to accommodate big families. C) They were sold to people before necessary facilities were installed. D) They provided playgrounds for children on the top of the buildings. ( A ) 33. The word “rage” (Line 9) means ________. A) be ignored B) develop with great force C) encourage people greatly D) be in fashion ( B ) 34. Some people oppose the building of flats because ________. A) the living expenses for each individual family are higher B) it involves higher cost compared with the building of houses C) they believe people like to live in houses with gardens D) the disposal of rubbish remains a problem for those living in flats ( C ) 35. The author mentions that people who live in suburban houses ________. A) do not have access to easy facilities because they live away from the city B) have to pay a lot of money to employ people to do service work C) take longer time to know each other because they are a scattered community D) have to spend more money and time travelling to work every day ( D ) Passage Four Questions 36 to 40 are based on the following passage. Where do pesticides ( 杀虫剂 ) fit into the picture of environmental disease? We have seen that they now pollute soil, water and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world: We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world. Responsible public health officials have pointed out that the biological effects of chemicals are cumulative ( 累积 ) over long periods of time, and that the danger to individual may depend on the sum of the exposures received throughout his lifetime. For these very reasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. “Men are naturally most impressed by diseases which have obvious signs,” says a wise physician, Dr. Rene Dubos, “yet some of their worst enemies slowly approach them unnoticed.” 36. Which of the following is closest in meaning to the sentence “Man... is part of nature” (Para. 1, Lines 3-4)? A) Man appears indifferent to what happens in nature. B) Man acts as if he does not belong to nature. C) Man can avoid the effects of environmental pollution. D) Man can escape his responsibilities for environmental effects of pesticides? ( B ) 37. What is the author’s attitude toward the environmental effects of pesticides? A) Pessimistic B) Indifferent C) Defensive D) Concerned ( D ) 38. In the author’s view, the sudden death caused by exposure to large amounts of pesticides ________. A) is not the worst of the negative consequences resulting from the use of pesticides B) now occurs most frequently among all accidental deaths C) has sharply increased so as to become the center of public attention D) is unavoidable because people can’t do without pesticides in farming ( A ) 39. People tend to ignore the delayed effects of exposure to chemical because ________. A) limited exposure to them does little harm to people’s health B) the present is more important for them than the future C) the danger does not become apparent immediately D) humans are capable of withstanding small amounts of poisoning ( C ) 40. It can be concluded from Dr. Dubos remarks that ________. A) people find invisible diseases difficult to deal with B) attacks by hidden enemies tend to be fatal C) diseases with obvious signs are easy to cure D) people tend to overlook hidden dangers caused by pesticides ( D )
