单选题{{B}}Passage 3{{/B}} Forget football. At many high schools, the fiercest competition is between Coke and Pepsi over exclusive "pouring rights" to sell on campus. But last week Jeffrey Dunn, president of Coca-Cola Americas, called a timeout: Coke's machines will now also stock water, juice, and other healthful options--even rival brands and their facades will feature school scenes and other "noncommercial graphics" instead of Coke's vivid red logo. "the pendulum needs to swing back" on school-based marketing, said Dunn. Coke's about-face--particularly the call to end the exclusive deals that bottlers make with school districts--comes amid rising concern over kids' health: American children are growing ever more obese and developing weight-related diseases usually found in adults. While inactivity and huge helpings factor heavily, a recent study in the Lancet fingered soda pop as a likely culprit. Communities--and legislators--are already on the case. Last year, for instance, parents in Philadelphia detailed a proposed contract with Coca-Cola that would have netted the school system $ 43 million over 10 years. And in a searing' report to congress last month, the U. S. Department of Agriculture recommended that all snacks sold in schools meet federal nutrition standards (the requirements are loose enough that Snickers bars qualify). Spare change? Activists hope Coke's capitulation will help curb commercialism in schools altogether. From ads on Channel One, which broadcasts current-affairs programs on classroom TV, to middle-school math texts that cite Nike and other bran-name products in their word problems, to company-sponsored scoreboards on football fields, American pupils are bombarded. But Andrew Hagelshaw, executive director of the Oakland, Calif.-based Center for Commercial-Free Public Education, views Coca-Cola's policy shift as a "partial victory". Schools sign contracts with local bottlers; the parent company can only urge them to back off. Moreover, Coke's machines will remain in place, although with healthier options. And don't expect teenagers to suddenly swear off the stuff--or school districts to give up the revenue. At Wheeler High School in Marietta, Ga., where students arrive before 7 a.m. and stay as late as 11 o'clock at night, they rely on the machines. And the $ 50,000 in annual vending revenues have enabled Principal Joe Boland to refinish the gym floor, in- stall a new high-jump pit, and pay $ 7,000 for two buses. "If someone made an offer to me to take the machines out, I'd consider it," says Boland. "But nobody's offering me any money."

单选题In the absence of optimism, we are left with nothing but critics, naysayers, and prophets of doom. When a nation expects the worst from its people and institutions, and its experts focus exclusively on faults, hope dies. Too many people spend too much time looking down rather than up, finding fault with their country's political institutions, economic system, educational establishment, religious organizations, and--worst of all--with each other. Fault finding expends so much negative energy that nothing is left over for positive action. It takes courage and strength to solve the genuine problems that afflict every society. Sure, there will always be things that need fixing. But the question is, do you want to spend your time and energy tearing things down or building them up? The staging of a Broadway show could illustrate my point. Let's say a new production is about to open. A playwright has polished the script, investors have put up the money, and the theater has been rented. A director has been chosen, actors have been auditioned and selected, and the cast has been rehearsing for weeks. Set, lighting, and sound engineers have been hard at work. By the time opening night arrives, nearly a hundred people have labored tirelessly--all working long hours to make magic for their audience. On opening night, four or five critics sit in the audience. If they pan it, the play will probably close in a matter of days or weeks. If they praise it, the production could go on for a long and successful run. In the end, success or failure might hinge on the opinion of a single person--someone who might be in a bad mood on opening night! What's wrong with this scene? In one sense, nothing. Critics have a legitimate role. The problem arises when we make critics our heroes or put them in control of our fate. When we empower the critic more than the playwright, something is wrong. It is much easier to criticize than to create. When we revere the critics of society, we eventually become a society of critics, and when that happens, there is no room left for constructive optimism.
