Text 2
When his plane touched down at Montreal' s international airport, David LaRoche collected his
luggage and headed for the airport parking garage, where he left his brand-new car three weeks earlier.
But the car wasn't there. LaRoche found a police officer, who gave him the bad news: his Audi A6
most likely had been absorbed into a vast black car market somewhere in Eastern Europe of Africa.
LaRoche, who flies out of Montreal because it is the closest major airport to his northern Ver-
mont home, is not alone. Countless U. S. travelers use Montreal' s airport because of its convenient location and competitive prices, which it promotes in radio ads in New England. Not surprisingly , the ads don' t mention that more than 200 cars are stolen every year from the airport' s parking lots.
Professional thieves search the airport' s long-term parking garages for cars that are relatively
free of dust and have U. S. license plates-a lack of dust means that a car was parked recently, and
Americans often travel for weeks on end. Says a Canadian car-theft investigator: "That gives the
bad guys a lot of time to do whatever they want with the car. " .
What they do, typically, is take the stolen cars to Montreal' s harbor, where they are con-
cealed inside huge containers to be taken overseas. In little more than a week, the cars are on the
street in Russia or countries in Africa of Asia. Police assert that Canada' s most powerful car-theft
rings are controlled by Russian crime organzations.
Airport. officials downplay the problem. "You have to put things in perspective.. . when you
have so many cars parked at your airport every year," says Montreal' s director of airport protec-
tion. "It' s not a major problem. " But the Montreal airport' s car-theft problem-police recorded
220 stolen cars last year - is far worse than other international airports in North America. Last
year, for example, only 65 cars were stolen from parking lots at Los Angeles' s airport; Boston's
Logan airport had only four reported thefts. So now David LaRoche will head to Logan, his next-
closest major airport. It's a longer drive, but that's OK if it saves his new car.
51. Many American travelers use Montreal international airport because _________
[A] it offers good passenger service
[B] it provides free parking lots
[C] it is near and inexpensive
[D] it is widely advertised

Memory
Psychologist George Spilich and colleagues at Washington College in Chester town, 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 also 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 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__________. 查看材料
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
