B
　　Have you ever dreamed about a trip to space? Seeds of some vegetables and crops are a lot luckier than you, as they have travelled to space and back.
　　China is among the three countries in the world that carry out agricultural （农业的）research in space. The others are Russia and the U.S. Since 1987, China has sent about 1000 kinds of seeds into space. These include green peppers, tomatoes, cucumbers, carrots and rice. Even on China’s first manned spacecraft Shenzhou V there were some seeds from Taiwan.
　　“Conditions in outer space such as radiation（辐射）and low gravity can cause big changes in the seeds,” said Chinese researcher Jin Xing.
　　But not all seeds are better after going to space. After returning to the earth, the best seeds are chosen. These seeds produce much more and also grow faster than normal seeds. As the safety of genetically modified（转基因）food is still being talked about, some people are not sure about the safety of these “space vegetables” because some of their genes are changed during the trip to space.
　　But Jin holds the more hopeful view. He said, “Unlike genetically modified crops, no new genes are introduced to the space vegetables, so they are surely safe.”
　　Space vegetables are better than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes. Another popular space vegetable is the peppers. Space peppers have 20 per cent more vitamin C than normal peppers.
　　Researchers are considering holding a tomato festival. By the time people will be able to enjoy about 30 different kinds of space tomatoes on their dining tables.
　　Following the tomato festival, other space vegetables, such as cucumbers, peppers, eggplants, tomatoes, beans, potatoes and pumpkins, would also go to markets with prices 30 to 50 percent higher than their common ones.
　　So far, the Chinese Academy of Sciences has set up three space vegetable base fields, one of which is in Shenzhen while the others are in Beijing and Jiangsu Province.

　　Even at school there had been an unhealthy competition between George and Richard.
　　“I’ll be the first millionaire in Coleford!” Richard used to boast(吹嘘).
　　“And you’ll be sorry you knew me,” George would reply “because I’ll be the best lawyer in the town!”
　　George never did become a lawyer and Richard never made any money. Instead both men opened bookshops on opposite sides of Coleford High Street. It was hard to make money from books, which made the competition between them worse.
　　Then Richard married a mysterious girl. The couple spent their honeymoon on the coast—but Richard never came back. The police found his wallet on a deserted beach but the body was never found. He must have died.
　　Now with only one bookshop in town, business was better for George. But sometimes he sat in his narrow, old kitchen and looked out of the dirty window, thinking about his formal rival(竞争对手). Perhaps he missed him?
　　George was very interested in old dictionaries. He’d recently found a collector in Australia who was selling a rare first edition(版本). When the parcel arrived, the book was in perfect condition and George was delighted. But while he was having lunch, George glanced(瞥视) at the photo in the newspaper that the book had been wrapped(裹、卷) in. He was shocked—the smiling face was older than he remembered but unmistakable! Shaking, George started reading.
　　“Bookends have bought ten bookstores from their rivals Dylans. The company, owned by multi-millionaire Richard Pike, is now the largest bookseller in Australia.”

　　C. He felt lucky with no rival in town.D. He was guilty of Richard’s death.
　　(   )10. George got information about Richard from ______.
　　A. a dictionary collector in AustraliaB. the latter’s rivals Dylans
　　C. a rare first edition of a dictionaryD. the wrapping paper of a book
　　(   )11. What happened to George and Richard in the end?
　　A. Both George and Richard became millionaires.
　　B. Both of them realized their original ambitions.
　　C. George established a successful business while Richard was missing.
