TEST 21-28 Since it has become known that several of a bank’s top executives have been buying shares in their own bank, the bank’s depositors, who had been worried by rumors that the bank faced impending financial collapse, have been greatly relieved. They reason that since top executtives evidently have faith in the bank’s financial soundness, those worrisome rumors must be false. They might well be overoptimistic, however since corporate executives have sometime bought shares in their own company in a calculated attempt to dispel negative rumors about the compamy’s health.
In the argument given, the two boldfaced portions play with which of the following roles?
A: the first summarizes the evidence used in the reasoning called into question by the argument; the second states the counterevidence on which the argument relies
B: the first summarizes the evidence used in the reasoning called into question by the argument; the second is an intermediate conclusion supported by that evidence
C: the first is an intermediate conclusion that forms part of the reasoning called into question by the argument; the second is evidence that undermine the support for this intermediate conclusion
D: the first is an intermediate conclusion that forms part of the reasoning called into question by the argument; the second is the main conclusion of the argument
E. the first is an intermediate conclusion that forms part of the reasoning called into question by the argument; the second states a further conclusion supported by this intermediate conclusion.
这题目我选D，但是似乎答案是E

TEST 21-33one of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream. Accordingly, entreprenerus have begun selling at aymnasiums and health clubs bottles of drinking water. Labeled”SuoerOXY”.that has extra oxygen dissolved in the water. Such water would be useless in inproving physical performance. However, since the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs.
Which of the following ,if true ,would serve the same function in the argument as the statement in boldface?
A: the water lost in exercising can be replaced with ordinary tap water
B: the amount of oxygen in the blood of people who are exercing is already more than the muscle cells can absorb
C: world-class atheletes turn in record rerformances without such water
D: frequent physical exercise increaases the body’s ablility to take in and use oxygen
E: lack of oxygen is not the only factor limiting human physical performance
这个题目我觉没有合适的答案，排除法的话也只能勉强选A。我觉的题目中BF的是判断Such water would be useless in inproving physical performance. 的依据，所以觉的5个选项中没有合适的。
望大家指教拉！
第一题选D；E错因为第一部分没有支持第二部分，第二部分的结论与第一部分是不符合滴；
第二题觉得应该选B，因为运动中滴人血液中滴氧气已经超过肌肉所能吸收的乐，再多也米有用，明显是支持结论滴；E也有一个弱支持，但还有其它因素限制与结论中间还缺少一个论证，即假设其它因素并没有满足人的要求，还有效用提升的空间；
仅供参考~~
经lukrenee点拨，觉的对33题明白了些。其实原句中的BF是对结论成立的假设或者说支持，所以我们在选项中找个假设或者支持的就好了，所以就选B了呀！
大家说是这样吧？
