　　Psychologist George Spilich and colleagues at Washington College in Chestertown, Maryland, decided to find out whether as many smokers say, smoking helps them to think and concentrate. Spilich put young non-smokers, active smokers and smokers deprived of cigarettes through a series of tests.

　　22. George Spilich s experiment was conducted in such a way as to _________.

　　A) compel the subjects to separate major information from minor details

　　B) put the subjects through increasingly complex tests

　　C) check the effectiveness of nicotine on smokers

　　D) register the prompt responses of the subjects

　　注：1.题目中没有具体指出是哪一个实验，所以就是针对所有提到的实验来说。

　　2.A 涉及文章倒数第二段的实验。

　　The fourth test required people to read a passage, then answer questions about it. Nonsmokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also had trouble separating important information from insignificant details.

　　3.C 涉及文章第三段的实验。

　　The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters transformed into a different one. Non-smokers were faster, but under the stimulation of nicotine , active smokers were faster than deprived smokers.

　　4.D 选项也只涉及文章中某一个实验。

　　23. The word bested most probably means ________.

　　A) beat B) envied

　　C) caught up with D) made the best of
