测试吸烟

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 (被剥夺) of cigarettes through a series of tests. In the first test, each subject (试验对象) sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple test, smokers, deprived smokers and nonsmokers performed equally well. 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 (尼古丁), active smokers were faster than deprived smokers. In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers. The fourth test required people to read a passage, then answer questions about it. Non-smokers 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 al so had trouble separating important information from insignificant details. “As our tests became more complex.”Sums up Spilich,“non-smokers performed better than smokers by wider and wider margins”He predicts,“smokers might per form adequately at many jobs-until they got complicated. A smoking airline pilot could fly adequately if no problems arose, but if something went wrong, smoking might damage his mental capacity.”

这是一篇说明文，讲的是关于测试吸烟是否有助于思考和集中精力的实验。

1. The purpose of George Spilich's experiments is _______.

A) to test whether smoking has a positive effect on the mental capacity of smokers

B) to show how smoking damages people's mental capacity

C) to prove that smoking affects people's regular performance

D) to find out whether smoking helps people's short-term memory

2. 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

3. The word“bested”(Line 3, Para. 5) most probably means _______.

A) beat B) envied C) caught up with D) made the best of

4. Which of the following statements is true?

A) Active smokers in general performed better than deprived smokers.

B) Active smokers responded more quickly than the other subjects.

C) Non-smokers were not better than other subjects in performing simple tasks.

D) Deprived smokers gave the slowest responses to the various tasks.

5. We can infer from the last paragraph that _______.

A) smokers should not expect to become airline pilots

B) smoking in emergency cases causes mental illness

C) no airline pilots smoke during flights

D) smokers may prove unequal to handing emergency cases

参考答案及解析

1、[答案及分析]：[A]事实辨认题，依据是第1段的两句话。

2、[答案及分析]：[B]本题问G有S的实验是以下列哪 种方式进行的。文章第2段说the first test是simple test,第3段开头说第2个实验more complex，最后一段开头说“随着测试逐渐变得复杂，不吸烟的人越来越比吸烟者做得好”，由此可见,George Spilich进行这种测试时以由易到难的顺序进行的。因而B项正确。

3、[答案及分析]：[A]词义推断题。我们可以看出该被要求推断词 义的词所在的上下文意为：没有被允许吸烟的人忧于那些在测试前片刻吸过烟的人。best在此句中是动词，意思应该是“优于、超过”。而四个选项的意思分别是：beat(击败，战胜)catch up with(赶上)make the best of(充分利用)。可以看出,best和beat意思最为接近。

4、[答案及分析]：[C]根据第2段第2句可知C项正确：另外，根据倒数第2段的后两句、第3段第2句可知A、B、D均不正确。

5、[答案及分析]：[D]与本题有关的信息在最后一段两句：Spilich认为，吸烟者能胜任并不复杂的工作，但不能胜行复杂的任务。一个吸烟的飞行员不出现任何问题时能称职也驾驶飞机飞行。但是一旦出现问题，吸烟就会损害他的大脑工作能力。

2019年大学英语四级考试阅读模拟试题一

American society is not nap friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine. "There's even a prohibition against admitting we need sleep". Nobody wants to be caught napping or found asleep at work. To quote a proverb: "Some sleep five hours, nature requires seven, laziness nine and wickedness eleven. " Wrong. The way not to fall asleep at work is to take naps when you need them. " We have to totally change our attitude toward napping", says Dr. William Dement of Stanford University, the godfather of sleep research. ? Last year a national commission led by Dement identified an "American sleep debt" which one member said was as important as the national debt, The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, president Clinton is trying to take a half?hour snooze every afternoon. ? About 60 percent of American adults nap when given the opportunity. We seem to have "a midafternoon quiet phase"also called"a secondary sleep gate. "Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap. ? We Superstars of Snooze don't nap to replace lost shut?eye or to prepare for a night shift. Rather, we"snack"on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums.

Choose correct answers to the question:

1. It is commonly accepted in American society that too much sleep is ______ .

A) unreasonable B) criminal C) harmful D) costly

2. The research done by the Dement commission shows that Americans ______ .

A) don't like to take naps

B) are terribly worried about their national debt

C) sleep less than is good for them

D) have caused many industrial and traffic accidents

3. The purpose of this article is to ______ .

A) warn us of the wickedness of napping

B) explain the danger of sleepiness

C) discuss the side effects of napping

D) convince the reader of the necessity of napping

4. The "American sleep debt"( Line 1, Para. 3) is the result of ______ .

A) the traditional misconception the Americans have about sleep

B) the new sleep policy of the Clinton Administration

C) the rapid development of American industry

D) the Americans' worry about the danger of sleepiness

5. The second sentence of the last paragraph tells us that it is ______ .

A) preferable to have a sound sleep before a night shift

B) good practice to eat something light before we go to bed

C) essential to make up for cost sleep

D) natural to take a nap whenever we feel the need for it

2019年大学英语四级考试阅读模拟试题二

Violin prodigies, I learned, have come in distinct waves from distinct regions. Most of the great performers if the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe. I asked Isaac Stern, one of the world's greatest violinists the reason for this phenomenon. "It is very clear," he told me. "They were all Jews(犹太人) and Jews at the time were severely oppressed and ill treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage. " As a result, every Jewish parent's dream was to have a child in the music school because it was a passport to the West. ?

Another element in the emergence of prodigies, I found, is a society that values

excellence in a certain field to nurture talent. Nowadays, the most nurturing societies seem to be in the Far East. "In Japan, a most competitive society, with stronger discipline than ours. " says Isaac Stem, children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War Ⅱ, that music not only became part of their daily lives, but it became a discipline as well. The Koreans and Chinese as we know, are just as highly motivated as the Japanese. ?

That's a good thing, because even prodigies must work hard. Next to hard work,

biological inheritance plays an important role in the making of a prodigy. J. S. Bach, for example, was the top of several generations of musicians, and four of his sons had significant careers in music.

Choose correct answers to the question:

1.Jewish parents in Eastern Europe longed for their children to attend music school because ______ .

A) it would allow them access to a better life in the West

B) Jewish children are born with excellent musical talent

C) they wanted their children to enter into the professional field

D) it would enable the family to get better treatment in their own country

2.Nurturing societies as mentioned in the passage refer to societies that ______ .

A) enforce strong discipline on students who want to achieve excellence

B) treasure talent and provide opportunities for its full development

C) encourage people to compete with each other

D) promise talented children high positions

3.Japan is described in the passage as a country that attaches importance to ______ .

A) all-round development. B) the learning of Western music

C) strict training of children D) variety in academic studies

4.Which of the following contributes to the emergence of musical prodigies according to the passage?

A) A natural gift. B) Extensive knowledge of music. C) Very early training. D) A prejudice-free society.

5.Which of the following titles best summarises the main idea of the passage?

A) Jewish Contribution to Music. B) Training of Musicians in the World C) Music and Society D) The Making of Prodigies
