17、 income goes up, but the national poverty rate remained at its highest level in eighteen years in 19The Census Bureau offered two possible explanations: the lingering effects of the deep and lengthy 1981 - 1982 recession, and increases in the number of people living in families headed by women and i

21、he moths larvae. The virus is always present in the larvae, but only every sixth or seventh year does the virus seriously decimate the number of larvae, thereby drastically setting back the gypsy moth population. Scientists believe that the virus, ordinarily latent, is triggered only when the larvae

22、 experience biological stress. If the scientists mentioned above are correct, it can be inferred that the decimation of gypsy moth larvae populations by the nuclear polyhedrosis virus would be most likely to be triggered by which of the following conditions? （ A） A shift from drought conditions to n

23、ormal precipitation in areas infested by gypsy moths. （ B） The escalating stress of defoliation sustained by trees attacked by gypsy moths for the second consecutive year. （ C） Predation on larvae of all kinds by parasitic wasps and flies. （ D） Starvation of the gypsy moth larvae as a result of over

The “method“ must b

25、e understood in terms of Stanislavski s personal search for release from the temptations of stock gestures, well-tried vocal intonations, and standard emotional formulas.

26、book of rigid solutions to acting problems.

29、s type O. Type O blood is essential for emergencies where there is no time for determining the blood type of victims because type O blood can be used for everyone. Type C)blood is unique in that it is compatible with blood of all types: any recipient, regardless of blood type, can be given it. But p

30、recisely because of this special usefulness, type O blood is chronically in short supply. If the statements in the passage above are true, which of the following must also be true? （ A） The special usefulness of type O blood lies in the fact that it matches the blood type of most people. （ B） Suppli

31、es of type O blood are continuously so low that type O blood is unavailable for emergencies, where its usefulness would be greatest. （ C） Forty-five percent of the total population of the United State has type O blood, which makes type O the most common blood type. （ D） Any decision to give blood of

32、 any type other than O needs to be based on knowledge of the recipients blood type. （ E） Type O blood is the only blood that cannot be typed as fast as needed in emergencies. 10 Dense snow cover can cause unusually harsh weather patterns to persist. If a severe winter storm blankets the Great Plains

33、, the snow cover reflects the suns radiation back into space and thus keeps the temperature of the ground low. Consequently, cold air moving down from Canada remains cold enough to cause more snowstorms. Which of the following is a conclusion that can be properly drawn from the information above? （

34、A） Winter weather on the Great Plains is the product of unusual movements of air masses. （ B） The Great Plains are more likely than other areas to suffer unusually harsh weather patterns. （ C） If the Great Plains get more snow than usual early in the winter and the snow remains until the spring thaw

35、, the winter is likely to be colder than usual. （ D） Even if the temperatures on the Great Plains are not extremely cold but are just below freezing, a moderate snowstorm will probably turn into a blizzard. （ E） The temperature of the ground depends primarily on the thickness of the snow cover. 11 C

36、onsider three fish swimming together in a school. The space within which each fish can be seen by predator Y is defined by a sphere centered on the fish and having a radius that is the maximum distance Y can see. The school is vulnerable to attack when Y is within one of the three spheres. The spher

37、es overlap to a great extent, since the fish are in a compact group. Which of the following is a reliable inference to be drawn from the passage above? （ A） The vulnerability to attack of the school as a whole is not much greater than the vulnerability to attack of any one fish in the school. （ B） T

38、here is less chance that predator Y will attack a school of four fish than that it will attack a school of three fish. （ C） Fish who swim in schools are less likely to be devoured by predators than are fish who do not swim in schools. （ D） The maximum distance at which an individual fish is visible

39、depends less on the size of the fish than on whether the fish is swimming in a school. （ E） The maximum distance at which predator Y can see its prey is increased if Y is itself swimming in a school of Ys. 12 Masterpieces of literature are “ intertextual,“ that is, they tend to be written in respons

40、e not to reality but to other works of literature. To the extent that a writing is intertextual, it becomes clouded as a mirror of social reality.

41、he writing is intertextual. （ B） The author who wishes to write a masterpiece should avoid being influenced by other works of literature. （ C） A writing that is not intertextual can have no significant relationship to any other writings. （ D） Literary masterpieces of the past are suspect as sources

42、of information about the social reality of the past. （ E） A work of literature is not intertextual if it is written in response to a writing that accurately mirrors social reality. 13 To many environmentalists, the extinction of plants accompanied by the increasing genetic uniformity of species of f

43、ood crops is the single most serious environmental problem. Something must be done to prevent the loss of wild food plants or no-longer-cultivated food plants. Otherwise, the lack of genetic diversity could allow a significant portion of a major crop to be destroyed overnight. In 1970, for example,

44、southern leaf blight destroyed approximately 20 percent of the United States corn crop, leaving very few varieties of corn unaffected in the areas over which the disease had spread. Which of the following can be inferred from the passage above? （ A） Susceptibility to certain plant diseases is geneti

45、cally determined. （ B） Eighty percent of the corn grown in the United States is resistant to southern leaf blight. （ C） The extinction of wild food plants can in almost every case be traced to destructive plant diseases. （ D） Plant breeders focus on developing plants that are resistant to plant dise

46、ase. （ E） Corn is the only food crop threatened by southern leaf blight. 14 A placebo is a chemically inert substance prescribed more for the mental relief of a patient than for its effect on the patients physical disorder. It is prescribed in the hope of instilling in the patient a positive attitud

47、e toward prospects for his or her recovery. In some cases, the placebo actually produces improvement in the patients condition. In discussing the use and effect of placebos, a well-known medical researcher recently paid physicians the somewhat offbeat compliment of saying that physicians were the ul

48、timate placebo. By comparing a physician to a placebo, the researcher sought to imply that （ A） physicians should always maintain and communicate an optimistic attitude toward their patients, regardless of the prognosis. （ B） the health of some patients can improve simply form their knowledge that t

49、hey are under a physicians care. （ C） many patients actually suffer from imagined illnesses that are best treated by placebos. （ D） physicians could prescribe less medication and achieve the same effect. （ E） it is difficult to determine what, if any, effect a physicians behavior has on a patients condition. 15 In a study of more than 8,000 people using ten beaches on two of the Great Lakes, ecologists from the University of Toronto determined that the rate of respiratory and gastrointestinal illness among people who had been swimming was 69.6 per 1,000, whereas the respiratory
