单选题{{B}}D{{/B}} If you're among the 24 million Americans who work from dusk to dawn, don't underestimate the physical and emotional costs of punching the clock in the dark. Compared with day workers, night workers are five times more likely to get stomach diseases, twice as likely to smoke cigarettes or use stimulants, and at higher risk for high blood pressure, heart. attack, and breast cancer. And if you have kids, your divorce risk is three to six times higher than normal. "You're out of sync with everything and everybody," says Acacia Aguirre, MD, PhD, author of an eye-opening new report. Your biological clock is thrown off, too. How to survive: "A healthy lifestyle matters even more," Aguirre says. "Exercise, limit coffee, and fit in 7 to 8 hours of sleep per day."

单选题{{B}}B{{/B}} We have a rather small house, with only one spare (多余的) bedroom. You can imagine (想象) our alarm (惊恐) when Aunt Clara wrote to say that she was coming with her children to stay for the weekend. Her family was not a small one, with four boys all under the age of twelve. I sent off a telegram (电报) at once, explaining that our house was too small. Aunt Clara called us up the next morning. "I forgot to mention (提到) to you, "she said in her sweetest voice, "the boys will be bringing their tents (帐篷) . " Even so, my wife was still worried. It was true we had a large garden, but there was still the problem of feeding (喂养) four growing boys. "And what if it rains? " she added. Luckily Saturday morning turned out to be bright and clear when I went to the station to meet Aunt Clara. I pushed the boys, together with the luggage (行李) , into the back of the car, with great difficulty of course. The youngest sat in front, with Aunt Clara and me. On the way home. I talked over the shoulder (肩) to David, the eldest boy, "I didn't see your tents among your luggage" "The tents! " cried David. " My God! We left them at home."

单选题If there is any single factor that makes success in living, it is the ability to be benefited by defeat. Every success I know has been achieved because the person was able to analyze (分析) defeat and actually learn something from it in his next undertaking (从事的工作). Wrongly taking defeat for failure, you are sure indeed to fail, for it isn't defeat that makes you fail; it is your own refusal to see the guide and encouragement to success in defeat. Defeats are nothing to be afraid of. They are common incidents in the life of every man who achieves success. But defeat is a dead loss unless you do face it, analyze it and learn why you failed. Defeat, in other words, can help to get rid of its own cause. Not only does defeat prepare us for success but nothing can cause within us such a strong wish to succeed. If you left a baby grasp a stick and try to pull it away, he will hold it more and more tightly until his whole weight is hung up. It is this same reaction that should give you new and greater strength every time you are defeated. If you make full use of the power which defeat gives; you can concrete with it fat' more than you are able to.

单选题{{B}}E{{/B}} The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structrue of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, We can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life-style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do. A multitude of factors, both inherited and environmental, influence the development of health-related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health-related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Crapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.

单选题Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobilizer(锁止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. The idea goes like this. A control box fitted to the car contains a mini-cell-phone, a microprocessor and memory, and a GPS(全球定位系统) satellite positioning receiver. If the car is stolen, a coded cell-phone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves. "The pattern of vehicle crime has changed," says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools, but only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code beamed out by the ignition(点火) key. In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 meters without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred meters minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit.
