单选题The chances are that you made up your mind about smoking a long time ago and decided it"s not for you. The chances are equally good that you know a lot of smokers—there are, after all about 60 million of them—work with them, and get along with them very well. And finally it"s a pretty safe bet that you"re open-minded and interested in all the various issues about smokers and non-smokers—or you wouldn"t be reading this. And those three things make you incredibly important today. Because they mean that it"s your voice—not the smoker"s and not the anti-smoker"s—that will determine how much of society"s efforts should go into building walls that separate us and how much into the search for solutions that bring us together. For one tragic result of the emphasis on building walls is the diversion of millions of dollars from scientific research on the causes and cures of diseases which, when all is said and done, still strike the non-smoker as well as the smoker. One prominent health organization, to cite but a single instance, now spends 28 cents of every publicly contributed dollar on "education" (much of it in anti-smoking propaganda) and only 2 cents on research. There will always be some who want to build walls, who want to separate people from people, and up to a point, even these may serve society. The anti-smoking wall-builders have, to give them their due, helped to make us all more keenly aware of choice. But our guess, and certainly our hope, is that you are among the far greatest members who know that walls are only temporary at best, and that over the long run, we can serve society"s interest better by working together in mutual accommodation. Whatever virtue walls may have, they can never move our society toward fundamental solutions. People who work together on common problems, common solutions, can.

单选题 The lives of very few Newark residents are untouched by violence: New Jersey's biggest city has seen it all Yet the murder of three young people, who were forced to kneel before being shot in the back of the head in a school playground on August 4th, has shaken the city. A fourth, who survived, was stabbed and shot in the face. The four victims were by all accounts good kids, all enrolled in college, all with a future. But the cruel murder, it seems, has at last forced Newarkers to say they have had enough. Grassroots organizations, like Stop Shootin’, have been flooded with offers of help and support since the killings. Yusef Ismail, its co-founder, says the group has been going door-to-door asking people to sign a pledge of non-violence. They hope to get 50000 to promise to "stop shootin’, start thinkin’, and keep livin’." The Newark Community Foundation, which was launched last month, announced on August 14th that it will help pay for {{U}}Community Eye{{/U}}, a surveillance (监视) system tailored towards gun crime. Cory Booker, who became mayor 13 months ago with a mission to revitalize the city, believes the surveillance program will be the largest camera and audio network in any American city. More than 30 cameras were installed earlier this summer and a further 50 will be installed soon in a seven-square-mile area where 80% of the city's recent shootings have occurred. And more cameras are planned. When a gunshot is detected, the surveillance camera zooms in on that spot. Similar technology in Chicago has increased arrests and decreased shootings. Mr. Booker plans to announce a comprehensive gun strategy later this week. Mr. Booker, as well as church leaders and others, believes (or hopes) that after the murder the city will no longer stand by in coldness. For generations, Newark has been paralyzed by poverty— almost one in three people lives below the poverty line—and growing indifference to crime. Some are skeptical. Steve Malanga of the conservative Manhattan Institute notes that Newark has deep social problems: over 60% of children are in homes without fathers. The school system, taken over by the state in 1995, is a mess. But there is also some cause for hope. Since Mr Booker was elected, there has been a rise in investment and re-zoning for development. Only around 7% of nearby Newark airport workers used to come from Newark; now, a year later, the figure is 30%. Mr Booker has' launched a New York-style war on crime. So far this year, crime has fallen 11% and shootings are down 30% (though the murder rate looks likely to match last year's high).
