第2题

In the first test, each subject 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 letters transformed into a different one. Nonsmokers were faster, but under the stimulation of nicotine active smokers were faster than deprived smokers.

In the third test of short - term memory, nonsmokers 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. Nonsmokers remembered 19 percent more of the most important information than active smokers, and deprived smoker 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.

As our tests became more complex, sums up Spilich, "nonsmokers performed better than smokers by wider and wider margins." He predicts, "smokers might perform. 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."

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

The unhealthy ingredients and low nutrition content of the food can make you less active a

nd lazy, new research shows. No surprises there.【C1】______, what is more shocking is that the energy-weakening effects of a junk food diet can persist,【C2】______after you switch to a healthy【C3】______. Two groups of female rats were fed different diets by researchers for a six-month period. One group ate unprocessed foods such as corn and fish meal【C4】______the other ate a diet【C5】______to imitate junk food; high in sugar, and lower in【C6】______. While understandably the group eating the junk food diet gained more weight than the other, they also【C7】______from fatigue and became less active and less【C8】______—ie: lazier. In fact, those rats fed junk food took twice as many, and longer breaks during tasks than the rats eating a healthy diet, even tasks which【C9】______rewards. What is even more【C10】______is that switching these rats back onto a nutritious diet at the end of six months for nine days didnt seem to reverse their weight gain or their learnt laziness. This could suggest that while an【C11】______case of bad food—say on holiday, will not have too much of a【C12】______effect if you generally eat a good diet and lead a healthy lifestyle. But those who eat a poor diet【C13】______the long term may actually become lazy and fatigued, as well as gaining weight and suffering the health consequences【C14】______being overweight. The research shows that switching【C15】______a healthy diet in the short term is unlikely to be【C16】______to reverse any of the side effects of a diet high in junk food. "Overweight people are often regarded as lazy and lacking【C17】______," says Blaisdell, a professor of psychology at UCLA "We【C18】______our results as suggesting that the idea commonly【C19】______in the media that people become fat because they are lazy is wrong. Our data suggest that diet-induced obesity is a cause,【C20】______an effect, of laziness. Either the highly processed diet causes fatigue or the diet causes obesity, which causes fatigue."

【C1】

A．Meanwhile

B．Therefore

C．However

D．Moreover

第4题

Coffee is one of the most popular drinks throughout the world today. In fact, according to

some estimates, over 30% of all adults in the world drink coffee at least once a day on the average. Coffee contains a kind of drug called caffeine. (66) Caffeine is a chemical substance that stimulates the nerves of the body. Drinking coffee tends to make people a little bit more awake, —at least for a short time—because of this stimulating effect on the nervous system. A cup of coffee has, on the average, about 3% caffeine in it.

One story of the discovery of the coffee plant relates to this effect of caffeine. According to the story, coffee was discovered in East Africa. The story says that coffee was first found by a goat farmer named Kaldi. This was about the year 850.

Kaldi was leading his animals through the mountains and the goats were stopping repeatedly to eat the plants near the path. Suddenly, some of the goats started jumping up and down in a very strange way.

Kaldi figured out that the goats were acting this way because of the plants they were eating. Kaldi himself tried eating some of the green beans that the goats had been eating. He, too, felt the stimulating effect of the beans.

Kaldi wanted to prove what had happened, so he picked some of the beans and took them back to his home village, where he told his story. The green bean got the name "Kaffa" and later "coffee" because the beans were discovered in a place called Kaffa in Africa.

Then for years, people used to eat a few of the green Kaffa beans when they were in the mountains and needed extra energy or stimulation. It was later found that the coffee beans could be picked and then dried until they turned brown, and then they could be stored. If the beans were dried and stored, they could be used at any time.

Caffeine is a kind of drug that can______.

A．strengthen one's heart

B．make one's bones strong

C．make one more active or alert

D．ease the pain on the body
