British and American scientists are raising genetically modified(转基因的) pigs in the hope of providing organs for transplant(移植) to humans, the project leader wrote in a newspaper Sunday.
Scientists in London and California have begun conducting the genetic experiments to find a solution to record–long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times.
In Britain alone, around 8,000 patients are waiting for a transplant.
"People needing a new heart or liver are waiting for someone else to die – usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans."
The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital.
Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets(猪仔), adding them to the animal's sperm(精子).
He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate.
The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri.
"Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote.
Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs.

Beijing: The highly anticipated Beijing-Shanghai high-speed railway will begin operation next year, and is expected to cut travel time to four hours, railway officials said.
The high-speed railway between China's two most important metropolises was scheduled to open in 2012 but will now open one year ahead of time, said Zheng Jian, chief planner with the Ministry of Railways.
Wang Zhiguo, vice-minister of railways, said that it would be a four-hour journey from Beijing to Shanghai, and only three hours from Beijing to Nanjing, capital of East China's Jiangsu province.
At present, it takes about 10 hours to travel from Beijing to Shanghai and Nanjing by train. A new-generation bullet train that will travel up to 380 kilometers per hour (kph) is now under development for the high-speed rail link.
It will be rigorously tested this year, and engineers want the train to run at a top speed of 420 kph to guarantee a safe operational speed of 380 kph, Huang Qiang, chief researcher with the China Academy of Railway Sciences told the Beijing News.
Vice-Minister Wang Zhiguo said it was expected that high-speed trains would one day take passengers from Beijing to most capital cities within eight hours, except for Haikou, Urumqi, Lhasa and Taipei.
It is expected that an 110,000-km railway network will be completed by 2012, including 13,000 km of high-speed rail, he said.
China already has 6,552 km of rail track in operation --- the longest amount of high-speed rail track in the world.
At present, at least 10,000 km of high-speed rail line is under construction in China. About 3,676 km of new track for running trains at speeds up to 350 kph have already been laid and put into operation. Another 2,876 km of old tracks have been upgraded to run trains of 200 to 250 kph. .
Ultimately, China plans to construct a 120,000-km railway network, including 50,000-km of high-speed rail track, by 2020.
The Ministry of Railways wants to export China's high-speed railway technology to North America, Europe and Latin America.
Wang said, “State-owned Chinese companies are already building high-speed lines in Turkey and Venezuela. Many countries, including the United States, Russia, Brazil and Saudi Arabia, have also expressed interest.”
56.When will the Beijing-Shanghai high-speed railway come into use?
A. In 2012. B. In 2013. C. In 2011. D. In 2010
57. How much time will a passenger save by train from Beijing to Shanghai after the high-speed railway is open?
A. 4 hours. B. 6 hours. C. 10 hours. D. 3 hours.
58. Which of the following countries owns the longest railway in the world ?
A. China. B. America. C. Canada. D. Russia.
59. Which city, in the opinion of vice-minister Wang Zhiguo, can passengers from Beijing reach in high-speed trains within 8 hours ?
A. Haikou. B. Urumqi. C. Lhasa . D. Changsha.
60. What can we learn from the last two paragraphs?
A. The Ministry of Railways wants to increase GDP by exporting railway technology.
B. China’s railway technology is superior to that of many other countries.
C. Countries in North America have already imported the railway technology of China.
D. The United States also wants to build high-speed railways in Turkey and Venezuela.

I went over to my grandmother’s house today and she didn’t have time for me. You see, the lady’s husband downstairs died and my Grandmother wanted to make some cookies for her. My grandmother did not analyze (分析) how the lady treated her, or if the lady needed any cookies, or even if the lady would like the cookies. She didn’t think how much the lady has done for her. She simply began baking.
My Grandmother turned 94 last week and this I believe is her secret to life. My grandmother is generous (慷慨) and hard-working in a way that is rare for our time. She lives by a simple belief: if someone needs your help, you help. Never mind all the analyzing and thinking whether the person deserves or appreciates the help. My grandmother doesn’t sit around thinking about who might be making use of her: she simply does what is needed.
At 94, she is busy in life. She is making a blanket for a new great grandchild, and worries that I don’t have enough kitchen towels for my home. She always brings soup to a sick neighbor, and teaches the new wife of her cousin (who is 88) how to cook Italian food.
My grandmother had every right to give up, but she didn’t — and amazingly life did bring her good things, like a husband with twinkling blue eyes who was much ahead of his time and believed that men should do an equal amount of cooking and cleaning in the home, three beautiful children (my father and two aunts), 22 grandchildren, and five great grandchildren. My grandmother is not afraid to give someone she barely knows a bowl of soup. She never keeps herself out of the world.
72. The reason why my grandmother made cookies for the lady downstairs is that ________.
A. she thought the lady was too busy
B. she would make them as thanks to her

73. In the writer’s opinion, ________.
A. my grandmother has a secret way of living
B. my grandmother does everything on careful consideration
C. few people are as generous as my grandmother now
D. my grandmother will get something in return
74. Which of the following is NOT true according to the passage?
A. My grandmother cares for her children even some strangers.
B. My grandfather does not treat women in an unfair way.
C. This is a family in which there are nearly 30 people now.
D. My grandmother never keeps everything for herself.
75. We may infer from the text that the writer ________.
A. thinks his grandmother is living a tired life
B. thinks his grandmother is doing what she should do
C. thinks his grandmother should not be so kind
D. is proud of his grandmother
Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea．People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches.
Tea remained scarce and very expensive in England until the ships of the East Indian Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.
At the same time people on the Continent were becoming more and more fond of tea．Until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added．She found it so pleasant that she would never again drink it without milk. Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few British drink tea without milk.
At first, tea was usually drunk after dinner in the evening. No one ever thought of drinking tea in the afternoon until a duchess (公爵夫人) found that a cup of tea and a piece of cake at three or four o’clock stopped her getting “a sinking feeling” as she called it. She invited her friends to have this new meal with her and so, tea-time was born.

In the 1880s, Mark Twain established and operated his own publishing firm. He also became interested in various investments, especially an elaborate typesetting machine. He lost almost $200,000 in investments in the machine between 1881 and 1894. Also, his publishing company declared bankruptcy (破产) in April 1894. Thus, in January 1895, Mark Twain found himself publicly shamed by his inability to pay his debts.
Mark Twain eventually recovered from his financial difficulties, through his continued writing and a successful lecture tour in 1895 and 1896. During this much-publicized tour, Twain lectured in such places as India, South Africa and Australia. By the time he returned, he had become an international hero. Twain enjoyed this attention, and his habits of smoking cigars or a pipe and wearing unconventional white suits contributed to his showy image. He also made use of his position as a public figure to criticize the US foreign policy.
Although he was recovering from his financial problems by 1898, Mark Twain had begun to experience tragedy in his personal life. Suzy, his oldest daughter, died of meningitis (脑膜炎) in 1896, while her parents and sister Clara were abroad. In 1903, Mark Twain sold the beloved house in Hartford, which had become too closely associated with Suzy’s death. His wife, Olivia, who had developed a heart condition, died on June 5, 1904. His youngest daughter, Jean, died on Dec. 24, 1909.
