We dont know what our Stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their p

9、roperties must be extremely ancient. They have always been enormously important to the welfare of people, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and many other purposes. Tribes living today in the jungle of the Amazon recognize hundreds of plants and know

10、 many properties of each. To them botany has no name and is probably not even recognized as a special branch of “knowledge“ at all. Unfortunately, the more industrialized we become the farther away we move from direct contact with plants. And the less distinct our knowledge of botany grows. Yet ever

11、yone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for r

12、icher yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, r

13、ather than getting a little here and a little there from many varieties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away. botany植物学 marvel令人惊奇的事 (人 )，奇迹 16 It is logical that a detailed learning of

27、es its tremendous popularity as a science and a scientific recreation to a simple circumstance that is sometimes forgotten when we weigh the eligibility(有被选资格，合适 )of different kinds of animals for informal study. Birds are day animals where others, just as engaging in their way mice, for instance ar

28、e creatures of the night. Apart from their visibility (something very much in their favor), the beauty of birds and their many appealing habits have won for them a huge fan following that has more than once tempted impatient and ill-informed laboratory biologists to dismiss ornithology as so much bi

29、rd-watching an absurdly unjust judgment that ignores the fact that ornithology has made a number of profoundly important contributions to general biology. Professional biologists are not hard put to reel off(滔滔不绝地讲 ) a list of distinctive contributions that ornithology has made to general biology sc

Irwins work on the immunologic performance of species of Columbidae(pigeons and doves) and of hybrids(杂交种 )between them. Then again, David Lacks studies on mortality in wild

31、 populations of birds are the most illuminating life tables of wild animals and animal demography (统计学 ) generally. Most important of all, perhaps is the contribution that ornithology has made to the study of animal behavior, beginning with Julian Huxley s classic study of the courtship habits of th

32、e great crested great and followed by Niko Tinbergens studies on the behavior of herring gulls. 31 What is the main idea of the passage? （ A） Birds are widely studied because they are popular in the home. （ B） Ornithology has made important contributions to biology. （ C） Professional biologists ofte

33、n engage in bird-watching for recreation. （ D） Animal behavior is best studied by observing birds. 32 Why mice are described in the passage as “creatures of the night“ because they are_. （ A） frightening to many people （ B） hunted by birds （ C） studied while in hibernation （ D） active after dark 33

34、Which of the following is NOT mentioned in the first as a reason for popular interest in birds? （ A） Their ecological value. （ B） Their appealing habits. （ C） Their visibility. （ D） Their beauty. 34 The pronoun “They“ in the second paragraph refers to_. （ A） ornithology and general biological scienc

36、ertisers claims that heat pumps can provide as many as two units of thermal energy for each unit of electrical energy used, thus apparently contradicting the principle of energy conservation. Heat pumps circulate a fluid refrigerant(致冷剂 ) that cycles alternatively from its liquid phase to its vapor

37、phase in a closed loop. The refrigerant, starting as a low-temperature, lowpressure vapor, enters a compressor driven by an electric motor. The refrigerant leaves the compressor as a hot, dense vapor and flows through a heat exchanger called the condenser, which transfers heat from the refrigerant t

38、o a body of air. Now the refrigerant, as a high-pressure, cooled liquid confronts a flow restriction which causes the pressure to drop. As the pres sure falls, the refrigerant expands and partially vaporizes, becoming chilled. It then passes through a second heat exchanger, the evaporator, which tra

39、nsfers heat from the air to the refrigerant, reducing the temperature o this second body of air. Of the two heat exchangers, one is located inside, and the other one outside the house, so each is in contact with a different body of air: room air and outside air, respectively. The flow direction of r

40、efrigerant through a heat pump is controlled by valves. When the refrigerant flow is reversed, the heat exchangers switch function. This flow-reversal capability allows heat exchangers switch function. This flow-reversal capability allows heat pumps either to heat or cool room air. Now, if under cer

41、tain conditions a heat pump puts out more thermal energy than it consumes in electrical energy, has the law of energy conservation been challenged? No, not even remotely: the additional input of thermal energy into the circulating refrigerant via the evaporator accounts for the difference in the ene

42、rgy equation. Unfortunately, there is one real problem. The heating capacity of a heat pump decreases as the outdoor temperature falls. The drop in capacity is caused by the lessening amount of refrigerant mass moved through the compressor at one time. The heating capacity is proportional to this ma

43、ss flow rate: the less the mass of refrigerant being compressed, the less the thermal load it can transfer through the heat-pump cycle. The volume low rate of refrigerant vapor through the single-speed rotary compressor used in heat pumps is approximately constant. But cold refrigerant vapor enterin

44、g a compressor is at lower pressure than warmer vapor. Therefore, the mass of cold refrigerant and thus the thermal energy it carries is less than ii the refrigerant vapor were warmer before compression. Here, then, lies a genuine drawback of heat pumps: in extremely cold climates where the most hea

45、t is needed heat pumps are least able to supply enough heat. 36 The primary purpose of the passage is to _. （ A） explain the differences in the working of a heat pump when the out-door temperature changes （ B） contrast the heating and the cooling modes of heat pumps （ C） describe heat pumps, their u

46、se, and actors affecting their use （ D） advocate the more widespread use of heat pumps 37 The author resolves the question of whether heat pumps run counter to the principle of energy conservation by _. （ A） carefully qualifying the meaning o that principle （ B） pointing out a factual error in the s

47、tatement that gives rise to this question （ C） supplying additional relevant facts （ D） denying the relevance of that principle to heat pumps. 38 It can be inferred from the passage that, in the course of a heating season, the heating capacity of a heat pump is greatest when _. （ A） heating is least

48、 essential （ B） electricity rates are lowest （ C） its compressor runs the fastest （ D） outdoor temperatures hold steady 39 If the authors assessment of the use of heat pumps (in the first paragraph) is correct, which of the following best expresses the lemon that advertisers should learn from this c

49、ase? （ A） Do not make exaggerated claims about the products you are trying to promote. （ B） Focus your advertising campaign on vague analogies and veiled implications instead of on facts. （ C） Do not use facts in your advertising that will strain the prospective client s ability to believe. （ D） Do not assume in your advertising that the prospective clients know even the most elementary scientific principles. 40 According to the passage, the role of the flo
