1、考博英语模拟试卷 84及答案与解析 一、 Reading Comprehension 0 One of the youngest independent countries in the Western Hemisphere, Trinidad and Tobago, became a nation on August 31, 1962. For a long time this nation has attracted tourists it is the home of calypso music and limbo dancing and in recent years its heal
2、thy economy has attracted investors as well. Trinidad and Tobago is a single country composed of two islands Trinidad, with the majority of the countrys 900,000 inhabitants, is a rectangle of roughly fifty by forty miles. Tobago, nineteen miles to the north, is smaller and has a population of about
3、35,000. Situated at the end of the long chain of Windward and Leeward Islands, Trinidad is at one point only seven miles off the coast of Venezuela. Its geology, flora, and fauna are similar to those of the South American mainland. Like Venezuela, the backbone of Trinidad and Tobagos economy is petr
4、oleum and its first colonists were Spaniards. Three mountain ranges, with summits of up to 3,000 feet, cross Trinidad from east to west, while Tobago is a relatively flat coral island, rimmed with fine beaches. The broad plains between Trinidads mountain ranges are dominated by vast fields of sugar
5、cane that present a symmetrical green pattern when seen from the air. A closer inspection reveals the coconut plantations along the coast and the profusion of brilliant red and yellow flowers of various species that are found all over the island. Houses on both islands tend to be light-colored, with
6、 an open style of architecture, in many cases with open space under the entire dwelling. Port-of-Spain, the capital, is a bustling modern city where the pulse of the people reflects Britist, Spanish, and East Indian influences. 1 The title below that best expresses the main idea of this passage is _

9、 the dilemma of the fungus: it is a plant, but it possesses no chlorophyl. While all other plants put the suns energy to work for them combining the nutrients of ground and air into body structure, the chlorophylless fungus must look elsewhere for an energy supply. It finds it in those other plants
10、which, having received their energy free from the sun, relinquish it at some point in their cycle either to other animals (like us humans) or to fungi. In this search for energy the fungus has become the earth s major source of rot and decay. Wherever you see mold forming on a piece of bread, or a p
11、ile of leaves turning to compost, or a blown-down tree becoming pulp on the ground, you are watching a fungus eating. Without fungus action the earth would be piled high with the dead plant life of past centuries. In fact, certain plants which contain resins that are toxic to fungi will last indefin
12、itely. Specimens of the redwood, for instance, can still be found resting on the forest floor centuries after having been blown down. 6 The title below that best expresses the main idea of this passage is _. （ A） Life without Chlorophyl （ B） The Source of Rot and Decay （ C） The Harmul Qualities of F
13、ungi （ D） The Strange World of the Fungus 7 The statement “you are watching a fungus eating“ is best described as _. （ A） figurative （ B） ironical （ C） parenthetical （ D） joking 8 The author implies that fungi _. （ A） are responsible for all the worlds rot and decay （ B） cannot live completely apart
14、 from other plants （ C） attack plants in order to kill them （ D） are poisonous to resin-producing plants 9 The author uses the word “dilemma“ to indicate that _. （ A） the fungus is both helpful and harmful in its effects （ B） no one understands how a fungus lives （ C） fungi are not really plants （ D
15、） the fungus seems to have its own biological laws 10 Which word best describes the fungus as depicted in the passage? （ A） Quixotic. （ B） Sporadic. （ C） Enigmatic. （ D） Parasitic. 10 In their world of darkness, it would seem likely that some of the animals might have become blind, as has happened t
16、o some cave fauna. So, indeed, many of them have, compensating for the lack of eyes with marvelously developed feelers and long, slender fins and processes with which they grope their way, like so many blind men with canes, their whole knowledge of friends, enemies, or food coming to them through th
17、e sense of touch. The last traces of plant life are left behind in the thin upper layer of water for no plant can live below about 600 feet even in very clear water, and few find enough sunlight for their food-manufacturing activities below 200 feet. Since no animal can make its own food, the creatu
18、res of the deeper waters live a strange, almost parasitic existence of utter dependence on the upper layers. These hungry carnivores prey fiercely and relentlessly upon each other, yet the whole community is ultimately dependent upon the slow rain of descending food particles from above. The compone
19、nts of this never-ending rain are the dead and dying plants and animals from the surface, or from one of the intermediate layers. For each of the horizontal zones or communities of the sea that lie between the surface and the sea bottom, the food supply is different and in general poorer than for th
20、e layer above. Pressure, darkness, and silence are the conditions of life in the deep sea. But we know now that the conception of the sea as a silent place is wholly false. Wide experience with hydrophones and other listening devices for the detection of submarines has proved that, around the shore
21、lines of much of the world, there is the extraordinary uproar produced by fishes, shrimps, porpoises and probably other forms not yet identified. There has been little investigation as yet of sound in the deep, offshore areas, but when the crew of the Atlantis lowered a hydrophone into deep water of
22、f Bermuda, they recorded strange mewing sounds, shrieks, and ghostly moans, the sources of which have not been traced. But fish of shallower zones have been captured and confined in aquaria, where their voices have been recorded for comparison with sounds heard at sea, and in many cases satisfactory
23、 identification can be made. During the Second World War the hydrophone network set up by the United States Navy to protect the entrance to Chesapeake Bay was temporarily made useless when, in the spring of 1942, the speakers at the surface began to give forth, every evening, a sound described as be
24、ing like “a pneumatic drill tearing up pavement“. The extraneous noises that came over the hydrophones completely masked the sounds of the passage of ships. Eventually it was discovered that the sounds were the voices of fish known as croakers, which in the spring move into Chesapeake Bay from the o
25、ffshore wintering grounds. As soon as the noise had been identified and analyzed, it was possible to screen it out with an electric filter, so that once more only the sounds of ships came thorugh the speakers. 11 Many underwater animals cannot see because _. （ A） the lack of light has gradually elim
26、inated their capacity to see （ B） they use sound waves instead of light to navigate in the darkness （ C） they have learned to survive without seeing their enemies or their prey （ D） their sense of touch has eliminated their need to see 12 According to the text, which of the following is NOT a use fo
27、r a hydrophone? （ A） To listen to the sound of undersea fauna. （ B） To search for unknown species of fish and other creatures. （ C） To monitor the passing of surface vessels. （ D） To detect submerged submarines. 13 Animals that live near the bottom of the sea are most likely to be carnivorous becaus
28、e _. （ A） they have developed sharp teeth and strong jaws with which to kill their prey （ B） plants that grow far below the surface are not edible （ C） animals cannot make their own food, so they eat each other （ D） most surface vegetation is eaten before it sinks to the bottom of the sea 14 Which o
29、f the following statements about the state of oceanographic research does the text most clearly support? （ A） Undersea research is still incomplete. （ B） Technology used in undersea studies is still in a very primitive stage of development. （ C） More undersea research is conducted near shore than in
30、 mid ocean. （ D） Military researchers have made several momentous discoveries about undersea life. 15 The authors main purpose in the text is to _. （ A） show that the United States coast was threatened by the enemy in World War （ B） explain some of the complexities of deepsea life （ C） illustrate th
31、e main problems faced by undersea researchers （ D） gain public support for oceanographic expeditions 15 The mental health movement in the United States began with a period of considerable enlightenment. Dorothea Dix was shocked to find the mentally ill in jails and almshouses and crusaded for the es
32、tablishment of asylums in which people could receive human care in hospital-like environments and treatment which might help restore them to sanity. By the mid 1800s, 20 states had established asylums, but during the late 1800s and early 1900s, in the face of economic depression, legislatures were u
33、nable to appropriate sufficient funds for decent care. Asylums became overcrowded and prison-like. Additionally, patients were more resistant to treatment than the pioneers in the mental health field had anticipated, and security and restraint were needed to protect patients and others. Mental insti
34、tutions became frightening and depressing places in which the rights of patients were all but forgotten. These conditions continued until after World War II. At that time, new treatments were discovered for some major mental illnesses theretofore considered untreatable (penicillin for syphilis of th
35、e brain and insulin treatment for schizophrenia and depressions), and a succession of books, motion pictures, and newspaper exposes called attention to the plight of the mentally ill. Improvements were made and Dr. David Vails Humane Practices Program is a beacon for today. But changes were slow in
36、coming until the early 1960s. At that time, the Civil Rights movement led lawyers to investigate Americas prisons, which were disproportionately populated by blacks, and they in turn followed prisoners into the only institutions that were worse than the prisons- the hospitals for the criminally insa
37、ne. The prisons were filled with angry young men who, encouraged by legal support, were quick to demand their rights. The hospitals for the criminally insane, by contrast, were populated with people who were considered “crazy“ and who were often kept obediently in their place through the use of seve
38、re bodily restraints and large doses of major tranquilizers. The young cadre of public interest lawyers liked their role in the mental hospitals. The lawyers found a population that was both passive and easy to champion. These were, after all, people who, unlike criminals, had done nothing wrong. An
39、d in many states, they were being kept in horrendous institutions, an injustice, which once exposed, was bound to shock the public and, particularly, the judicial conscience. Patients rights groups successfully encouraged reform by lobbying in state legislatures. Judicial interventions have had some
40、 definite positive effects, but there is growing awareness that courts cannot provide the standards and the review mechanisms that assure good patient care. The details of providing day-to-day care simply cannot be mandated by a court, so it is time to take from the courts the responsibility for del
41、ivery of mental health care and assurance of patient rights and return it to the state mental healty administrators to whom the mandate was originally given. Though it is a difficult task, administrators must undertake to write rules and standards and to provide the training and surveillance to assu
42、re that treatment is given and patient rights are respected. 16 The main purpose of the passage is to _. （ A） provide a historical perspective on problems of mental health care （ B） increase public awareness of the plight of the mentally ill （ C） shock the reader with vivid descriptions of asylums （
43、 D） describe the invention of new treatments for mental illness 17 The authors attitude toward people who are patients in state institutions can best be described as _. （ A） inflexible and insensitive （ B） detached and neutral （ C） understanding and sympathetic （ D） enthusiastic and supportive 18 It
44、 can be inferred from the passage that, had the Civil Rights movement not prompted an investigation of prison conditions, _. （ A） states would never have established asylums for the mentally ill （ B） new treatments for major mental illness would have likely remained untested （ C） the Civil Rights mo
45、vement in America would have been politically ineffective （ D） conditions in mental hospitals might have escaped judicial scrutiny 19 The tone of the final paragraph can best be described as _. （ A） overly emotional （ B） cleverly deceptive （ C） cautiously optimistic （ D） fiercely independent 20 Acco
46、rding to the passage, mental hospital conditions were radically changed because of _. （ A） a group of young angry men in the 1900s （ B） active young lawyers in the 1960s （ C） innocent insane patients protest （ D） powerful court interventions 二、 Structure and Vocabulary 21 The medieval church condemn
47、ed mans partaking in _ pleasures. （ A） educational （ B） ascetic （ C） asexual （ D） sensual 22 The new machine failed to _ the garbage. As a result, the kitchen was filled to bursting with smelly leftovers. （ A） expand （ B） compact （ C） produce （ D） criticize 23 According to legend, Daniel Webster mad
48、e a _ with Satan, but managed to talk his way out of it at the last moment. （ A） economy （ B） standard （ C） van （ D） compact 24 When her purse fell overboard, Sally lost her _, keys, wallet, and cigarettes. （ A） vehicle （ B） piano （ C） compact （ D） complexion 25 After completing her usual morning ch
49、ores, Linda found herself _ tired. （ A） surprisingly （ B） buoyantly （ C） forcibly （ D） unceasingly 26 The presence of armed guards _ us from doing anything disruptive. （ A） defeated （ B） irritated （ C） prevented （ D） encouraged 27 A careful _ of the house revealed no clues. （ A） dissemination （ B） pursuit （ C） ornamentation （ D） examination 28 Though many thought him a tedious old man, he had a _ spirit that delighted his friends. （ A） juve
