单选题The Aerospace Bicycle That Fell to Earth A radical new bicycle had its first public showing at the National British Cycling Championships in Shrewsbury last weekend. Based on the gold medal-winning design from the Barcelona Olympics, it is the first commercial mountain bike made of a single piece of carbon fibre. Bicycles for amateurs have up to now been made of steel, aluminum or magnesium tubes welded together into the conventional "A-frame"shape. But last year, the British competitor Chris Boardman set world records while winning titles in the Olympic cycling pursuit events on a custom built, carbon-fibre bicycle with lower weight and wind resistance than standard models. Because carbon fibre is both light and extremely strong, it does not need the A-frame shape, saving further weight. Carbon fibre can also be moulded in a single piece, avoiding the weakness of welds. The new bike, which will cost between $ 2000 and $ 3000 when it reaches the shops next month, has the same advantages as the Olympic model. It weighs about 11 kilograms,a saving of 1.5 kilograms on metal frames. With no crossbar, it has a lower center of gravity, making it easier to use in race conditions. "When you're doing some aggressive riding,you throw the bike about from side to side," explains Eddie Eccleston, director of British Eagle, a British bicycle manufacturer based in Powys, Wales, which is marketing the bikes. "The low centre of gravity gives you better control. " The frames are being made in the U. S. for British Eagle by SP systems in Camarillo,California, which has clients in the aerospace industry, "This is aerospace technology brought into cycling by enthusiasts", says Eccleston. When professionals tested racing versions of the bike before the Tour de France, they were quicker than metal versions by up to 3 seconds per kilometer. The new design has no struts between the saddle and the back wheel; instead, the frame's flexibility can be "tuned" to individual tastes by changing the mixture of Kevlar fibre and carbon fibre in the back wheel strut, allowing up to 5 centimeters of movement. The carbon-fibre design has a lower centre of gravity and smoother back-wheel suspension than conventional bikes.

单选题Americans usually consider themselves a friendly people. Their friendships, however, tend to be shorter and more casual than friendships among people from other cultures. It is not uncommon for Americans to have only one close friend during their lifetime, and consider other "friends" to be just social acquaintances. This attitude probably has something to do with American mobility and the fact that Americans do not like to be dependent on other people. They tend to "compartmentalize (划分) friendships, having "friends at work", "friends on the softball team", "family friends", etc. Because the United States is a highly active society, full of movement and change, people always seem to be on the go. In this highly changed atmosphere, Americans can sometimes seem brusque (无礼的) or impatient. They want to get to know you as quickly as possible and then move on to something else. Sometimes, early on, they will ask you questions that you may feel very personal. No insult is intended; the questions usually grow out of their genuine interest or curiosity, and their impatience to get to the heart of the matter. And the same goes for you. If you do not understand certain American behavior or you want to know more about them, do not hesitate to ask them questions about themselves. Americans are usually eager to explain all about their country or anything "American" in which you may be interested. So much so in fact that you may become tired of listening. It doesn"t matter because Americans tend to be uncomfortable with silence during a conversation. They would rather talk about the weather or the latest sports scores, for example, than deal with silence. On the other hand, don"t expect Americans to be knowledgeable about international geography or world affairs, unless those subjects directly involve the United States. Because the United States is not surrounded by many other nations, some Americans tend to ignore the rest of the world.
