单选题Creating a World without Smoking Smoking will be banned in all pubs, clubs and workplaces from next year after historic votes in the Commons last night. After last-minute appeals from health campaigners, MPs opted for a blanket prohibition which will start in summer 2007, ending months of argument over whether smokers should be barred in pubs and restaurants only. They voted to ban smoking in all pubs and clubs by 384 to 184, a surprisingly large majority of 200. Smoking will still be allowed in the home and in places considered to he homes, such as prisons, care homes and hotels. Smokers lighting up in banned areas will face a fixed penalty notice of ￡50 and spot fines of ￡200 will be introduced for failing to display no-smoking signs, with the possible penalty, if the issue goes to court, increasing to ￡1,000. Carpline Flint, the Public Health Minister, also announced that the fine for failing to stop people smoking in banned areas would be increased to ￡2,500—more than ten times the ￡200 originally proposed. The Bill also allows the Government to increase the age for buying cigarettes. Ministers will consult on raising it from 16 to 18. The Bill now goes to the Lords but will be through by the summer recess. Even a plan to allow smoking to continue in private clubs was thrown out as MPs on all sides were given permission to vote with their conscience rather than on a party line. Patricia Hewitt, the Health Secretary, said the Health Bill would ban smoking in "virtually every enclosed public place and workplace" in England and save thousands of lives a year. Smoke-free workplaces and public places "will become the norm". She said: "An additional 600,000 people will give up smoking as a result of this law and millions more will be protected from second-hand smoke." Peter Hollins, director-general of the British Heart Foundation, said: "The vote is a landmark victory for the public health of this country and will save the lives of many people."

单选题{{B}}第一篇{{/B}} Electric Backpack Backpacks are convenient. They can hold your books, your lunch, and a charge of clothes, leaving your hands free to do other things. Someday, if you don't mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home. Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass. , have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack's electricity-generating feature could dramatically reduce the amount of a wearer's load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9 Science. The backpack's electricity-crew, ring powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer's back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7.4 watts. Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack's oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack. The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren't on the market yet, but if you do get one eventually, just make sure to look both ways be{ore crossing the street!

单选题Trying to Find a Partner One of the most striking findings of a recent poll in the UK is that of the people interviewed, one in two believes that it is becoming more difficult to meet someone to star a family with. Why are many finding it increasingly difficult to start and sustain intimate relationships? Does modern life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for economic security or status. A man doesn't expect his spouse to be in sole charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence. In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soulmate (心上人) was constrained (限制) by geography, social convention and family tradition. Although it was never explicit, many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster (牡蛎), you surely have a better chance of finding a pearl. But it seems that the old conventions have been replaced by an even tighter constraint: the tyranny of choice. The expectations of partners are inflated (提高) to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression. We think that a relationship can be perfect. If it isn't, it is disposable. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Of course, this is complicated by realities. The cost of housing and child-rearing creates pressure to have a stable income and career before a life partnership.

单选题{{B}}第三篇{{/B}} {{B}} Differences of Policemen{{/B}} Real policemen hardly recognize any resemblance between their lives and what they see on TV. The first difference is that a policeman's real life revolves round criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down a street after someone he wants to talk to. Little of his time is spent in chatting, he will spend most of his working life typing mil- lions of words on thousands of forms about hundreds of sad, unimportant people who are guilty of stupid, petty crimes. Most television crime drama is about finding the criminal: as soon as he's arrested, the story is over. In real life, finding criminals is seldom much of a problem. Except in very serious cases like murders and terrorist attacks little effort is spent on searching. Having made an arrest, a detective really starts to work. He has to prove his case in court and to do that he often has to gather a lot of difference evidence. At third big difference between the drama detective and the real one is the unpleasant pressures: first, as members of a police force they always have to behave absolutely in accordance with the law; secondly, as expensive public servants they have to get results. They can hardly ever do both. Most of the time some of them have to break the rules in small ways. If the detective has to deceive the world, the world often deceives him. Hardly anyone he meets tells him the truth. And this separation the detective feels between himself and the rest of the world is deepened by the simple-mindedness—as he sees it—of citizens, social workers, doctors, law-makers, and judges, who, instead of eliminating crime punish the criminals less severely in the hope that this will make them reform. The result, detectives feel, is that nine tenths of their work is recatching people who should have stayed behind bars. This makes them rather cynical.
