After reading the passage, choose the best answer to each questi

27、on. Answer all questions following the passage on the basis of what is stated or implied in the passage. The complex life cycle of the Plasmodium protozoan, the causative agent of malaria, has contributed to the difficulty of devising effective public health measures to combat the disease. It took s

28、cientists centuries to deconstruct the basic relationship between protozoan, mosquito vector, and human host. Modern physiologists and epidemiologists are still working out the intricacies of malarial infection. The disease is transmitted by the bite of a female Anopheles mosquito infected with the

29、Plasmodium parasite. Only Anopheles mosquitoes are capable of transmitting the disease, and only females take blood meals from humans. To become infected with Plasmodium, the female mosquito takes a blood meal from a human carrying the parasite in his or her blood. Once ingested, the parasite mature

30、s in the mosquitos gut for approximately a week, after which it migrates to the insects salivary glands. By mixing with the mosquitos saliva, the parasite facilitates its transmission to a human host when the mosquito bites that human. Once in a humans bloodstream, the parasite travels to the humans

31、 liver. At this initial stage, the Plasmodium parasite is called a sporozoite. Within the liver, the sporozoite can form 30,000 to 40,000 daughter cells, called merozoites, which are released into the hosts bloodstream at a later date, sometimes within a week of the initial infection and sometimes a

32、s much as several months later. The merozoites seek out and attach themselves to red blood cells, in which they incubate 8 to 24 daughter cells over the next two days. When the daughter cells are mature, the red blood cell ruptures and the new parasites are released into the bloodstream to seek out

33、red blood cells of their own. Some of the new merozoites become male and female gametocytes; if these gametocytes are ingested by a mosquito feeding on the hosts blood, they will fertilize in the mosquitos gut to produce new sporozoites, and the cycle will continue. The symptoms that we associate wi

34、th malaria-a high, recurring fever; joint pain; a swollen spleen-are caused by toxins released from the red blood cells ruptured by merozoites. The human spleen can destroy these infected blood cells, but the Plasmodium parasite counters this effect by increasing the stickiness of proteins on the bl

35、ood cells surfaces so that the cells stick to the walls of blood vessels. If the sticky surface proteins affect a particularly large number of cells, the malaria can trans-form into a hemorrhagic fever, the most deadly form of malaria. A further complicating factor in the natural history of malaria

36、is the many variants of the Plasmodium protozoan. Scientists now recognize that malaria is caused by at least six different species: P. falciparum, P. vivax, P. ovale, P. malariae, P. knowesli, and P. semiovale. Of these species, P. falciparum accounts for the majority of infections and approximatel

37、y 90 percent of malarial deaths in the world. 10 The passage is primarily concerned with which of the following? （ A） Describing the life cycle of the Plasmodium protozoan as it relates to the disease malaria （ B） Comparing and contrasting the life cycles of the six variants of the Plasmodium protoz

38、oan known to cause malaria （ C） Addressing the public health implications of the life cycle of the Plasmodium parasite （ D） Providing information on how a person can avoid infection with malaria （ E） Describing the life cycle of the Anopheles mosquito as it relates to the transmission of the Plasmod

39、ium protozoan to humans 11 Which of the following most accurately states the role of the first paragraph in relation to the passage as a whole? （ A） It summarizes two theories, the relative merits of which are debated in the passage. （ B） It puts forth an argument that the rest of the passage is dev

40、oted to refuting. （ C） It introduces a new concept that the rest of the passage expands upon. （ D） It frames the background and relevance of the material to follow. （ E） It outlines the major themes of each of the four paragraphs to follow. 12 If a mosquito were to bite a person, and that person wer

41、e later to develop malaria and die of the disease, it is most likely that the person was infected with which of the following? （ A） Anopheles gambiae （ B） Anopheles semiovale （ C） Plasmodium malariae （ D） Plasmodium uivax （ E） Plasmodium falciparum 13 The relationship of a merozoite to a sporozoite

42、is most like which of the following? （ A） A mother to a daughter （ B） A brother to a sister （ C） One of several subsidiaries spun off from a large corporation （ D） A computer program to a computer （ E） Orange juice to an orange tree 14 Based on the information given in the passage, which of the foll

43、owing would be most effective in preventing a person infected with malaria from developing a hemorrhagic fever? （ A） Surgical removal of the spleen （ B） A medicine that prevents changes to the surface proteins of red blood cells （ C） An effective vaccine against malaria （ D） A potent pesticide that

44、reliably kills the Anopheles mosquito without producing any negative consequences for the environment or for human health （ E） A small infusion of a weaker variant of the Plasmodium protozoan that will then compete with the existing parasitic infection 15 In fisheries in general, when a large harves

45、t is taken one year, there will be fewer fish available to be harvested in the following year, leading to decreasing yields of most fish species over time. The Maine lobster is an anomaly, however. Even though the vast number of lobster traps covering the New England coast pull in more lobsters ever

46、y year, the number of lobsters in the water has shown no signs of decreasing. Which of the following, if true, most helps to explain the apparent anomaly concerning the number of Maine lobsters? （ A） The decline of other fish species in the region has deprived the lobster of its natural food source

47、of scavenged fish. （ B） The bait in lobster traps provides abundant food for young lobsters, which are still small enough to swim out of the traps, leading to much higher survival rates among young lobsters than would be expected in nature. （ C） As global warming heats the waters of the Atlantic coa

48、stline, the Maine lobster has extended its northern range to well past Nova Scotia. （ D） The ever-increasing demand for lobsters in seafood restaurants and steakhouses across the country has driven a corresponding increase in the supply of the product. （ E） The increased lobster harvest has resulted

49、 in many juvenile lobsters but very few breeding-age lobsters, which could result in a crash in lobster numbers in the near future. 16 Federal tax evasion is a serious crime that places an unfair tax burden on those members of society who pay their fair share. To reduce the incidence of tax evasion, the government needs to prosecute a few high-profile individuals whose cases will receive substantial media attention. The argument above relies on which of the following assumptions? （ A） The tax system is so complicated that even people who try to comply with it may inadver
