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 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.”

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.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.

3.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

13. His plan is such a good one ____ we all agreed to accept it.

After a heat discussion, our class has decided to recommend Li Hua as the Touching Figure On the Campus. We have several reason to believe he is qualified for the honor. First, Li Hua is always willing to offering us help whenever necessary. Besides, his great devotion to work as a monitor make our class a best place to study. However, it has impressed us most is his unconditional love to poor children. Last summer vacation, he volunteered to teach English in a small village, which has been inspired many other students to join in and thus helped open up a new world to those children as well.

All in all, his selfless love touches our heart and his action suggests that even small efforts should make difference to those in need. Therefore, we strong support Li Hua as the Touching Figure Campus.
