[单项选择]Passage One At many colleges, smokers are being run not just out of school buildings but off the premises. On Nov. 19 , the University of Kentucky, the tobacco state’s flagship public institution, Launched a campus wide ban on cigarettes and all other forms of tobacco on school grounds and parking areas. Pro-nicotine students staged a “smoke-out”to protest the new policy, which even rules out smoking inside cars if they’re on school property. Kentucky joins more than 365 U. S. colleges and universities that in recent years have instituted antismoking rules both indoors and out. In most places, the issue doesn’t seem to be secondhand smoke. Rather, the rationale for going smoke-free in wide open spaces is a desire to model healthy behavior. Purdue University, which has 30-ft. buffer zones, recently considered adopting a campuswide ban but tempered its proposal after receiving campus input. Smoking will now be restricted to limited outdoor areas.

[填空题]Choosing a date to stop will help smokers get prepared mentally.

[单项选择]For years, smokers have been exhorted to take the initiative and quit: use a nicotine patch, chew nicotine gum, take a prescription medication that can help, call a help line, just say no. But a new study finds that stopping is seldom an individual decision. Smokers tend to quit in groups, the study finds, which means smoking cessation programs should work best if they focus on groups rather than individuals. It also means that people may help many more than just themselves by quitting: quitting can have a ripple effect prompting an entire social network to break the habit.
The study, by Dr. Nicholas Christakis of Harvard Medical School and James Fowler of the University of California, San Diego, followed thousands of smokers and nonsmokers for 32 years, from 1971 until 2003, studying them as part of a large network of relatives, co-workers, neighbors, friends and friends of friends.
It was a time when the percentage of adult smokers in the United States fell to 21 percent

[单项选择]Smokers who want to kick the habit might soon get help from a product that’s being tested at the University at Buffalo School of Dental Medicine: a mouth wash that makes cigarettes taste bad. It could be on the market within a year.
The anti-smoking rinse itself tastes rather pleasant. But if you light up within 6 to 8 hours of smoking it, your cigarette will taste like burnt rubber and you won’t smoke past the first puff, explains Dr. Sebastian Ciancio, director of the Center for Dental Studies at the University of Buffalo.
Ciancio is heading up a pilot study in which 10 smokers, each of whom normally smoke at least a pack of cigarettes a day, are rinsing their mouths three times daily with the anti-smoking solution. Another 10 are getting a placebo. Prior to this study, only the inventor had tested the anti-smoking rinse—a chemist who does not wish to be identified—and a few of his friends, who say it enabled them to quit smoking.
And Ciancio has no shortage of v
A. Metal ions.
B. A chemist.
C. A smoker.
D. Dr. Sebastian Cianeio.
