题型有：1.74 miles. The scientists’ argument depends on which of the following

assumptions?

A．The microorganisms brought up were of a species that is related to those

previously known to science.

B．No holes have been drilled into the Earth’ s surface to a distance deeper than 1.

74 miles.

C．The microorganisms did not come from surface soil that came into contact

with the drilling equipment.

D．The stratum from which the samples came has been below the surface of the

Earth ever since the Earth came into existence.E．The temperature at the bottom of the

holes drilled was not significantly hotter than that of the hottest spots on the Earth’s

surface.

正确答案：C

解析：本题根据从地表以下1．74英里深的地方取得的样品中存在活着的微生物，得出了在地层深处存在活着的微生物的结论，属于典型的“B，A”模式。要想使本题的结论成立，就必须寻找一个原因来解释或加强样品确实取自地层深处，即排除他因。由此分析可知(C)为正确答案；(E)是较易误选的选项，从表面上看它似乎能对普遍的猜想构成反对，从而对本题的结论构成支持。但是要知道，地表以下温度太高是一个既定的事实，那些科学家的实验只是为了证实地层深处存在微生物的可能性，而不是要证实微生物一定要在和地面表层温度相一致的温度区间内才能存活，因此(E)为错误选项。 知识模块：逻辑推理

16． Automobile exhaust is a serious pollution problem in Riverside, and

instituting tolls at Riverside’s bridges would reduce the total number of miles traveled

by automobiles. Nevertheless, overall pollution levels would not decrease because

there would be long lines at the toll booths, and automobiles expel more exhaust per

minute while idling than in any other driving situation. The argument above depends

on which of the following assumptions?

A．Any reduction in automobile exhaust resulting from a reduction in the miles

traveled by cars would be matched or surpassed by the additional exhaust resulting

from toll lines.

B．Cars in Riverside spend more time, on average, idling than they do in other

driving situations.

C．Increasing automobile exhaust at the bridges will not significantly affect air

pollution because few drivers use the bridges in Riverside frequently.

D．Reducing automobile exhaust is not the most effective way of reducing air

pollution.E．The inconvenience of idling in the long toll lines at Riverside’ s bridges

will cause most drivers to change their driving routes, not the amount of driving that

they do.

17． One state adds a 7 percent sales tax to the price of most products purchased

within its jurisdiction. This tax, therefore, if viewed as tax on income, has the reverse

effect of the federal income tax: the lower the income, the higher the annual

percentage rate at which the income is taxed. The conclusion above would be properly

drawn if which of the following were assumed as a premise?

A．The amount of money citizens spend on products subject to the state tax tends

to be equal across income levels.

B．The federal income tax favors citizens with high incomes, whereas the state

sales tax favors citizens with low incomes.

C．Citizens with low annual incomes can afford to pay a relatively higher

percentage of their incomes in state sales tax, since their federal income tax is

relatively low.

D．The lower a state’s sales tax, the more it will tend to redistribute income from

the more affluent citizens to the rest of society.E．Citizens who fail to earn federally

taxable income are also exempt from the state sales tax.

正确答案：A

解析：转化为数学去思维可很容易得出(A)为答案，并可对(A)进行取非验证。

18． The interview is an essential part of a successful hiring program because,

with it, job applicants who have personalities that are unsuited to the requirements of

the job will be eliminated from consideration.The argument above logically depends

on which of the following assumptions?

A．A hiring program will be successful if it includes interviews.

B．The interview is a more important part of a successful hiring program than is

the development of a job description.

C．Interviewers can accurately identify applicants whose personalities are

unsuited to the requirements of the job.

D．The only purpose of an interview is to evaluate whether job applicants’

personalities are suited to the requirements of the job.E．The fit of job applicants’

personalities to the requirements of the job was once the most important factor in

making hiring decisions.

19． A recent report determined that although only three percent of drivers on

Maryland highways equipped their vehicles with radar detectors, thirty-three percent

of all vehicles ticketed for exceeding the speed limit were equipped with them.

Clearly, drivers who equip their vehicles with radar detectors are more likely to

exceed the speed limit regularly than are drivers who do not.The conclusion drawn
