【正文】 Country Y appointed a censor to prohibit the publication of any book critical of Country Y’s government。 all new books legally published in the country after 1712 were approved by a censor. Under the first censor, one half of the book manuscripts submitted to the censor were not approved for publication. Under the next censor, only one quarter of the book manuscripts submitted were not approved, but the number of book manuscripts that were approved was the same under both censors. If the statements in the passage are true, which one of the following can be properly concluded from them? A. More books critical of Country Y’s governments were published before the appointment of the first censor than after it. B. The first censor and the second censor prohibited the publication of the same number of book manuscripts. C. More book manuscripts were submitted for approval to the first censor than to the second. D. The second censor allowed some book manuscripts to the published that the first censor would have considered critical of Country Y’s government. E. The number of writers who wrote unpublished manuscripts was greater under the first censor than under the second. 參考思路：同5，又是一道計算題。關(guān)鍵還是列出公式。the number of book manuscripts that were approved was the same under both censors.Numbers of the first censor checked x (150%) = Numbers of the second censor x (125%)So (C) More book manuscripts were submitted for approval to the first censor than to the second. 14. If the government increases its funding for civilian scientific research, private patrons and industries will believe that such research has bee primarily the government’s responsibility. When they believe that research is no longer primarily their responsibility, private patrons and industries will decrease their contributions toward research. Therefore, in order to keep from depressing the overall level of funding for civilian scientific research, the government should not increase its own funding. Which one of the following is an assumption on which the argument relies? A. Governments should bear the majority of the financial burden of funding for civilian scientific research. B. Any increase in government funding would displace more private funding for civilian scientific research than it would provide. C. Private donations toward research are no longer weled by researchers whose work receives government funding. D. Civilian scientific research cannot be conducted efficiently with more than one source of funding. E. funding for civilian scientific research is currently at the highest possible level. 參考思路：本題指出private funding for civilian scientific research和government funding是一增一減的關(guān)系。如果兩者的增長數(shù)量是一樣的，則總量不會隨其中之一而變化。而如果一方的變化是另一方變化量的系數(shù)倍，則總量將會受到影響(B) Any increase in government funding would displace more private funding for civilian scientific research than it would provide. 這個選項指出了第二鐘變化趨勢。Therefore, in order to keep from depressing the overall level of funding for civilian scientific research, the government should not increase its own funding. 我們應(yīng)該假設(shè)Any increase in government funding would displace more private funding for civilian scientific research than it would provide.。 b is correct.15. Dental researcher: Filling a cavity in a tooth is not a harmless procedure: it inevitably damages some of the healthy parts of the tooth. Cavities are harmful only if the decay reaches the nerves inside the tooth, and many cavities, if left untreated, never progress to that point. Therefore, dentists should not fill a cavity unless the nerves inside the tooth are in imminent danger from that cavity. Which one of the following principles, if valid, most strongly supports the researcher’s reasoning? A. Dentists should perform any procedure that is likely to be beneficial in the long term, but only if the procedure does not cause immediate damage. B. Dentists should help their patients to prevent cavities rather than waiting until cavities are present to begin treatment. C. A condition that is only potentially harmful should not be treated using a method that is definitely harmful. D. A condition that is typically progressive should not be treated using methods that provide only temporary relief. E. A condition that is potentially harmful should not be left untreated unless it can be kept under constant surveillance. 答案：C思路：搭橋法，建立A與B的聯(lián)系作者指出：補牙對牙齒的健康部分是一定有害的。而牙洞只有在已經(jīng)露出神經(jīng)后才是有害的。可是這種情形幾乎不可能出現(xiàn)。因此牙醫(yī)不應(yīng)該隨便給病人補牙除非牙齦神經(jīng)已經(jīng)露出。A, 提到無關(guān)信息：beneficial in the long term。B, 與題目相反C, 有效的建立了兩者的關(guān)系，即對于潛在的傷害不應(yīng)用必然帶來其他傷害的方法來治療。D, 無關(guān)信息排除E, 沒有建立起有效的連接。16. The axis of Earth’s daily rotation is tilted with respect to the plane of its orbit at an angle of roughly 23 degrees. That angle can be kept fairly stable only by the gravitational influence of Earth’s large, nearby Moon. Without such a stable and moderate axis tilt, a planet’s climate is too extreme and unstable to support life. Mars, for example, has only very small moons, tilts at wildly fluctuating angles, and cannot support life. If the statements above are true, which one of the following must also be true on the basis of them? A. If Mars had a sufficiently large nearby moon, Mars would be able to support life. B. If Earth’s Moon were to leave Earth’s orbit, Earth’s climate would be unable to support life. C. Any planet with a stable, moderate axis tilt can support life. D. Gravitational influences other than moons have little or no effect on the magnitude of the tilt angle of either Earth’s or Mars’s axis. E. No planet that has more than one moon can support life. 參考思路：A only by B。 B是A的必要條件, 非B推出非A。If Earth’s Moon were to leave Earth’s orbit 〉That angle cannot be kept fairly stable 224。a planet’s climate is too extreme and unstable to support life.( based on Without such a stable and moderate axis tilt, a planet’s climate is too extreme and unstable to support life.)(B) If Earth’s Moon were
