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.

Feed the World with Potatoes1 As food prices continue to rise rapidly, there is growing concern about the effect it will have among the world"s poor.2 Increasingly, experts are looking to the potato as a possible low-cost solution to feeding the hungry. To emphasize the issue, the United Nations has called the potato "a hidden treasure", and named 2008 the International Year of the Potato. Here"s how potatoes could end the food crisis.3 The potato matures more quickly, on less land and in harsher climates than most other major crops. Up to 85 percent of the plant is eatable, compared with around 50 percent of cereals. Its broad adaptability to a wide variety of farming systems is also noteworthy.4 Potatoes are an excellent source of complex carbohydrates ( 碳水化合物), which release their energy slowly, and have only 5 percent of wheat"s fat content. They contain only a quarter of the calories of bread and, according to the Potato Center, when boiled, potatoes have more protein and nearly twice the calcium (钙) as corn. Additionally, they are good sources of vitamin C, iron, potassium (钾) and zinc (锌).5 The Food and Agricultural Organization recently surveyed food price inflation in over 70 of the poor countries. Cereal price inflation was much higher and far more widespread than for potatoes. A significant factor behind the potato"s affordability is the fact that unlike other agricultural products, the potato is not yet a global commodity, and has therefore not attracted speculative investors. Raw potatoes are heavy and can rot during transit, so global trade has been slow to take off. Also, potatoes are susceptible (易受影响的) to infection with disease, hindering (阻碍) export. According to analysts" estimates, less than 5 percent of potatoes are traded internationally, with prices driven primarily by local tastes instead of international demand. Paragraph 5 ______
Time to Stop Traveling by AirTwenty-five years ago a young British man called Mark Ellingham decided that he wanted a change of scenery. So he went to Australia, stopping off in many countries in between. He also decided to write about the experience and produced a guide for other travelers making similar journeys.In 1970, British airports were used by 32 million people. In 2004, the figure was 216 million. In 2030, according to government forecasts, it will be around 500 million. It"s a growth driven by the emergence of low cost airlines, offering access to all parts of the world for less than ￡100.This has made a huge contribution to global warming. One return flight from Britain to the US produces the same carbon dioxide (二氧化碳) as a year"s motoring (驾车). A return flight to Australia equals the emissions (排放) of three average cars for a year. And the pollution is released at a height where its effect on climate change is more than double that on the ground.Mark Ellingham built his business on helping people travel. Now he wants to help people stop—at least by air.He is calling for a ￡100 green tax on all flights to Europe and Africa, and ￡250 on flights to the rest of the world. He also wants investment to create a low-carbon economy, as well as a halt to airport expansion.Mark Ellingham"s commitment is important because his readers aren"t just the sort of young and adventurous people who would happily jump on a plane to spend a weekend exploring a foreign culture. They are also the sort of people who say they care about the environment. It"s a debate that splits people down the middle.The tourist industry has responded by offering offsetting (补偿) schemes. A small increase in the price of a ticket is used to plant trees.But critics say that it is not enough to just be carbon neutral. We should be actively cutting back on putting greenhouse gases into the atmosphere. And for the average person, making a plane journey will be his or her largest contribution to global warming. It may be good to repair the damage we do. But surely it is better not to do the damage in the first place. Critics argue that the best way to protect our environment is not to do any damage to it.
