Freezing to Death for BeautyPeople in Beijing wear a lot of clothing during winter to fend off (抵御) the cold. In the United States, however, people wear 1 , partly because the car is the primary mode of transportation. Cars take 2 straight to their workplaces, which are heated well. The American diet is full of calories, so their 3 can afford to burn heat more quickly.Fewer layers of clothing give people the opportunity to stay 4 . Lots of Yale girls wear skirts 5 when it"s 10 degrees Centigrade outside. Some of them at least wear boots, tights, and leg-warmers. Some, however, really just go for the look 6 the risk of health. These girls have no pants to prevent their 7 , and no socks to protect their feet. A mini skirt and a pair of stilettos (细高跟鞋) are all that they wear.Typically, the ones pursuing fashion are 8 , with little body fat. Just by the nature of their bodies, they are already at a disadvantage compared with normal people in 9 weather. I have always 10 , whenever I pass these girls, how they manage to refrain from shivering and just smile like spring had arrived.And then there are the guys. The girls can be said to 11 health for beauty. But why do guys 12 so little It is not like, once they take off some layers, they suddenly become better-looking. They are not exactly being fashionable when they 13 wear sporty (花哨的) shorts and shower slippers in the midst of winter. It"s not cute(喜人的).Of course, people have the freedom to look whatever 14 they want. I am just surprised that, given the vast difference between winter and summer temperatures in Connecticut, they can still 15 like they are partying on the beach in the middle of February.

Electric BackpackBackpacks are convenient. They can hold your books, your lunch, and a change 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 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 (接收器), night-vision goggles (夜视镜), and other battery-powered devices to get around and do their work. The backpack"s electricity-generating feature could greatly reduce the amount of a wearer"s load now devoted to spare batteries.The backpack"s electricity-creating powers depend onspringsused to hang a cloth pack from its metal frame. The whole pack moves up and down as the person walks. A special mechanism converts movements of the pack to electricity, which can be as much as 7.4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits (步法) in response to the pack"s oscillations (摆动), 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 nonelectric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers (登山运动员), 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 before crossing the street! According to Paragraph 4, Rome plans to ______.
The best option would be to cancel the trip altogether.
Covering the Cost All by HimselfUniversity life is in no way cheap in Canada. It costs Peter Kemp, a computer science major at the British Columbia Institute of Technology in Vancouver, C $18,000 a year. Amazingly, the 21-year-old is covering the cost by himself.For the past three years, Kemp has done a range of part-time jobs to pay for his tuition and living expenses. Last semester alone, he worked five jobs for 32-40 hours a week. Life is busy, but Kemp enjoys it."Doing part-time jobs gives me economic independence," said Kemp, who will begin his senior year this fall. "Having economic independence gives me the ability to take control of my life and make my own decisions," said Kemp. "It has also helped me understand the value of money."Among Kemp"s five jobs last semester, two were on campus. For one, he helped maintain the university"s computer labs. For the other, he worked at the IT service desk to help students and teachers solve their computer problems. He also worked for a small company that develops GPS systems. This job paid him well at C $27 an hour."These jobs made me put what I"ve learned in university to practical use," Kemp said. "I accomplished creative and imaginative tasks by applying my abilities to the work."Good time management skills help Kemp balance work and study. He"s a top student in his class. And he will be the student association chairman for his department beginning next semester. It"s a position that he has desired for a long time. "It will give me the opportunity to be the voice for my fellow students and make a difference," says Kemp."I believe one of the key secrets to juggling (应对) everything is to avoidputting offtasks. This can leave you stressed and reduce the quality of your work and health," he said."I often make a list of the things I need to do each day and rank them by their importance. The list helps me decide what task I should do first and when I should complete it. Remember to ask for help when you think you can"t finish something on time, or can"t finish it by yourself." The phrase "putting off" in Paragraph 7 means ______.
