1、GMAT（ VERBAL）逻辑推理模拟试卷 1及答案与解析 1 A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high immune-system activity. The researcher concluded from this experiment that the immune system protect

2、s against mental illness as well as against physical disease. The researcher s conclusion would be most seriously weakened if it were true that （ A） there was a one-year delay between the completion of a pilot study for the experiment and the initiation of the experiment itself. （ B） peoples levels

3、of immune-system activity are not affected by their use of medications. （ C） a few people with high immune-system activity had scores on the test of mental health that were similar to the scores of people who had normal immune-system activity. （ D） people who have low immune-system activity tend to

4、contract more viral infections than do people with normal or high immune-system activity. （ E） high levels of stress first cause mental illness and then cause decreased immune-system activity in normal individuals. 2 The skulls and pelvic bones of some species of dinosaur share characteristics with

5、the skulls and pelvic bones of all modern birds.

The ice melted quickly after the car was warmed up the next morning because the defrosting vent, which blows only on the fr

8、ont windshield, was turned on full force.

9、ce there melted at the same rate as did the ice on the front windshield. （ C） The speed at which ice on a window melts increases as the temperature of the air blown on the window increases. （ D） The warm air from the defrosting vent for the front windshield cools rapidly as it dissipates throughout

10、the rest of the car. （ E） The defrosting vent operates efficiently even when the heater, which blows warm air toward the feet or faces of the driver and passengers, is on. 4 Pandas are rapidly disappearing from the wild.

Once

14、, very few people in New York City could be found sporting cowboy boots and Stetson hats, and no major radio station boasted twenty-four-hour-a-day programming of country and western music. The latest development is the rapid proliferation of restaurants serving chili, nachos, burritos, and other Te

17、rs ago. 6 Popular culture in the United States has become Europeanized to an extent unimaginable twenty-five years ago. Not many people then drank wine with meals, and no one drank imported mineral water. No idea would have been more astonishing than that Americans would pay to watch soccer games. S

23、. 8 A small dose of widely used tranquilizer allows people to lie during lie detector tests without being discovered.

24、ffective in reducing stress in everyday situations. An assumption of the passage is that （ A） tranquilizers are always an effective treatment for stress. （ B） the inhibition of stress responses increases subjective stress. （ C） stress as measured by a lie detector is similar to everyday stress. （ D）

25、 persons who lie during a lie detector test always display signs of stress. （ E） it is not desirable to reduce stress in everyday situations. 9 Even though most universities retain the royalties from faculty members inventions, the faculty members retain the royalties from books and articles they wr

26、ite. Therefore, faculty members should retain the royalties from the educational computer software they develop. The conclusion above would be more reasonably drawn if which of the following were inserted into the argument as an additional premise? （ A） Royalties from inventions are higher than roya

27、lties from educational software programs. （ B） Faculty members are more likely to produce educational software programs than inventions. （ C） Inventions bring more prestige to universities than do books and articles. （ D） In the experience of most universities, educational software programs are more

28、 marketable than are books and articles. （ E） In terms of the criteria used to award royalties, educational software programs are more nearly comparable to books and articles than to inventions. 10 When limitations were in effect on nuclear-arms testing, people tended to save more of their money, bu

29、t when nuclear-arms testing increased, people tended to spend more of their money.

30、tastrophe has increased over the years. （ B） most people supported the development of nuclear arms. （ C） peoples perception of the threat of nuclear catastrophe depends on the amount of nuclear-arms testing being done. （ D） the people who saved the most money when nuclear-arms testing was limited we

31、re the ones who supported such limitations. （ E） there are more consumer goods available when nuclear-arms testing increases. 11 If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar, most of the private-plane traf

32、fic would be forced to use outlying airfields. Such a reduction in the amount of private-plane traffic would reduce the risk of midair collision around the centrally located airports. The conclusion drawn in the first sentence depends on which of the following assumptions? （ A） Outlying airfields wo

33、uld be as convenient as centrally located airports for most pilots of private planes. （ B） Most outlying airfields are not equipped to handle commercial-airline traffic. （ C） Most private planes that use centrally located airports are not equipped with radar. （ D） Commercial airliners are at greater

34、 risk of becoming involved in midair collisions than are private planes. （ E） A reduction in the risk of midair collision would eventually lead to increases in commercial-airline traffic. 12 Traditionally, decision-making by managers that is reasoned step-by-step has been considered preferable to in

35、tuitive decision-making. However, a recent study found that top managers used intuition significantly more than did most middle or lower-level managers. This confirms the alternative view that intuition is actually more effective than careful, methodical reasoning. The conclusion above is based on w

37、e and lower-level managers can be made as easily by using methodical reasoning as by using intuitive reasoning. （ D） Top managers use intuitive reasoning in making the majority of their decisions. （ E） Top managers are more effective at decision-making than middle or lower-level managers. 13 A famou

38、s singer recently won a lawsuit against an advertising firm for using another singer in a commercial to evoke the famous singer s well-known rendition of a certain song. As a result of the lawsuit, advertising firms will stop using imitators in commercials. Therefore, advertising costs will rise, si
