LONDON (Reuters)--New faces given to a Chinese man after a bear tore off part of his face and a FrenchCaribbean man disfigured by a rare tumor show that such transplants can work and are not medical oddities ,researchers said. The findings give hope to some people with severe facial disfigurement and suggest the transplants could prove longlasting without major problems.Despite the tissue rejection in the first year after their transplants,neither men had psychological problems accepting their new faces and have been able to rejoin society,they reported. Only three people have received face transplants.The world's first was carried out on French woman Isabelle Dinoire in November 2005 after she was disfigured in an attack by her dog.In 2007,her doctors reported that she had recovered slowly and steadily,overcoming two periods of rejection. In 2006,Chinese doctors performed a face transplant on a 30yearold hit by a bear.While there were some complications with tissue rejection following the operation,two years later the man was doing well,his doctors said."This case suggests that facial transplantation might be an option for _ a severely disfigured face,and could enable patients to bring themselves back into society," Shuzhong Guo and colleagues at Xijing Hospital in China wrote. A French team described their work on a 29yearold man who suffered from Von Recklinghausen disease,an illness that changes the shape of his face."The man,who was not named,was given a new nose,mouth and chin in a 2007 operation.He began to work 13 months after the transplant has more function in his face and has not rejected the new tissue," his doctors said. "Our case confirms that face transplantation is practical and effective for the correction of specific disfigurement," Dr.Laurent Lantieri and colleagues at the HenriMondor hospital outside Paris wrote. From the passage we can learn that _ . A) doctors have different opinions on facial disfigurement B) patients could regain selfconfidence after face transplants C) the new face of every patient has more functions than expected D) it is easy for disabled people to be accepted by society

When my brother and I were young, my mom would take us on Transportation Days. It goes like this: You can't take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We'd take the train into the city center, then a bus, switching to the tram, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn't like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom's friend was waiting to give us a ride home--our first car ride of the day. The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal . She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence--the product of a childhood not spent exploring subway tunnels. Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just light-rail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox--and often an inadequate one, limiting both your mobility and your wallet. On Transportation Days, we might stop for lunch on Chestnut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where's the stop, and will I get wet when we go under the river? I'm writing this right now on an airplane, a means we didn't try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me... Which means of transportation does the writer probably disapprove of? A) Airplane. B) Subway. C) Tram. D) Car.

Q: Decision-thinking is not unlike poker --it often matters not only what you think, but also what others think you think and what you think they think you think.The mental process is similar.Naturally,this card game has often been of considerable interest to people who are,by any standards,good thinkers. The great mathematician John von Neumann was one of the founders of game theory.In particular,he showed that all games fall into two classes:there are what he called games of 'perfect information', games like chess where the players can't hide anything or play tricks:they don't win by chance,but by means of logic and skills.Then there are games of 'imperfect information', 1ike poker,in which it is impossible to know in advance that one course of action is better than another. One mistaken idea about business is that it can be treated as a game of perfect information.Quite the reverse.Business,politics,life itself are games which we must normally play with very imperfect information.Business decisions are often made with many unknown and unknowable factors which would even puzzle best poker players.But few business people find it comfortable to admit that they are taking a chance,and many still prefer to believe that they are playing chess,not poker. In the writer's opinion,when making business decisions one should_. A) put perfect information before imperfect information B) accept the existence of unknown factors C) regard business as a game of chess D) mix known and unknown factors

Albert Einstein (1879--1955) was one of the greatest and most original scientific thinkers of all time. Born of Jewish parents at Ulm in Germany,he completed his education in Switzerland and got his Ph. D at the University of Zurich. He went to live in the United States in 1933 because of the rise of Nazism in Germany and Hitler's persecution of the Jews. In 1905, while still at Zurich, he published his Special Theory of Relativity, which was based on things everyone may have noticed. If two trains are standing alongside each other and one train starts to move, a person sitting in the train may wonder whether his own train is moving or the other is moving, and before he finds out what is happening, he can see that one train is moving ly to the other. From this and also from other more complicated facts, Einstein came to the conclusion that all motion is and that there are really no such things as motion. Some of the other conclusions he drew are that nothing can go faster than light, and that if something such as a ruler was moving faster and faster it would seem to get shorter and shorter as its speed was near the speed of light. By 1915, Einstein had made his General Theory of Relativity known. He also improved on Newton's theory of gravity. Most of his theories have been tested and found to be true though some may sound strange. For his important work he was awarded the 1921 Nobel Prize for Physics. In 1933, Einstein went to live in the United States because _ . A) he loved the USA more than his own country B) he could no longer work in Germany when Hitler came into power C) he wanted to live quietly in the US D) he had got some friends there with whom he could work together
