问题:问答题Practice 3 Dolly was no ordinary lamb. She was cloned from a single mammary cell of an adult ewe, overturning long- held scientific dogma that had declared such a thing biologically impossible. Her birth set off a race in laboratories around the world to duplicate the breakthrough and raised the specter of human cloning. A decade later, scientists are starting to come to grips with just how different Dolly was. Dozens of animals have been cloned since that first little lamb and it’s becoming increasingly clear that they are all, in one way or another, defective. It’s tempting to think of clones as perfect carbon copies of the original—down to every hair and quirk of temperament. It turns out, though, that there are various degrees of genetic replication. Not only are clones separated from the original template by time—-in Dolly’s case, six years—but they are also the product of an unnatural molecular mechanism that turns out not to be very good at making identical copies. But scientists see a role for cloning in treating human diseases—and perhaps someday conquering some of man’s most intractable conditions. It may be another 10 years or more before the approach yields anything safe and reliable enough to be used in real patients, and there is no guarantee that it will ever be successful. But nobody thought Dolly was possible until she made history that warm July night 10 years ago.

问题:问答题Practice 4 Bluetooth is the newest kid on the technology block, and it holds a lot of promise for the assistive technology industry. Named for a 10th Century King of Denmark who unified the kingdoms of Denmark and Norway, Bluetooth is a shot-range wireless communication specification that promises to improve and increase electronic access to a number of environments by overcoming some of the obstacles typical of current technology. Bluetooth technology will enable devices to communicate and transfer data wirelessly and without the line-of-site issues of infra red technology. So how does it work? Bluetooth devices search each other out within their given operational range. Unlike devices that are wired together, Bluetooth devices do not have to be aware of the capabilities or properties of the devices to which they will connect beforehand. Bluetooth devices have a built-in mechanism that lets each device identify itself as well as its capabilities as it connects into this new Bluetooth network. This dynamic network does have a controlling device that designates itself as the master for the connection. Its programming and the capabilities necessary for the given task determine whether or not a device can be a master. For example, a cell phone may act as a master device when connecting to a headset, an ATM, or an information kiosk. However, the same cell phone or headset may act as a slave device to the information kiosk, now acting as the master device, broadcasting emergency evacuation information. The cell phone and kiosk can function in either capacity depending on the required function and their programming.

问题:问答题Passage 4 When philanthropist Jeffrey Brewer heard the founder of Appro TEC speak in San Francisco recently, he was intrigued by the nonprofit’s high-tech efforts to fight poverty and create jobs in Africa. But he wanted to learn more before shelling out money, so he scheduled a meeting with the founder. “I wasn’t sure it was as good as it sounded,” says Brewer, who lives in New York. Six months later, he boarded a plane for Kenya—at ApproTEC’s behest—to check out their programs in person. “It turned out to be better.” Forget slide shows or annual reports. Charitable organizations are finding that field visits are far more effective marketing tools for deep-pocket donors looking for new experiences. The invitation—only travel programs allow donors, who typically don’t mind paying their own way, to see firsthand what their money can accomplish. Such field trips—whether to AIDS orphanages in China, famine-relief programs in Sudan or earthquake-proof building sites in Indonesia—almost always result in increased awareness and bigger checks. Some donors become more active in the aid organization—Brewer now chairs ApproTEC’s boardd—or throw fund-raising parties. “Lifetime passionate supporters means first they fall in love with the people and places that they meet,” says Sherry Villanueva, Who started organizing trips two years ago as a board member of Direct Relief International, which supplies medical and financial aid to locally run health programs. “We’re not sitting around on a fancy deck somewhere with waiters in white gloves.” Indeed, donor trips tend to mix fun with the fund-raising. Miracle Corners of the World, which provides small-business training and housing for young adults in Tanzania, will host its first donor trip in August, with a safari in addition to the ribbon—cutting ceremony at its new housing project. Last month, the London-based International Childcare Trust cycled 300 kilometers in southern India to raise money for children orphaned by the tsunami. The Philanthropy Workshop, a program cosponsored by the Rockefeller Foundation that acts as a boot camp for new donors, recently sent 14 participants to Uganda for a week to look at innovative school reform for girls and sustainable farming—as well as some gorillas in the bush. While some critics argue that charities should focus on honing their mission statements instead of organizing adventure trips, others say only a field visit can change a donor’s view of the world. “I had a lot of ideas of how to fix Africa before I went over—and all of them were wrong,” says Brewer. “I felt very humbled.” Roderic Mast, the founder of Conservation International’s donor travel program, CI-Sojourns, which enables top supporters to investigate endangered ecosystems around the globe, says he owes the rise in million-dollar-plus contributions to the growing popularity of his nature trips, up from three in 2000 to 13 this year. On one recent trip, Mast recalls how he left a donor and his wife on a beach in Michoacan, Mexico, at night to watch a nesting sea turtle. At breakfast the next morning, they marveled over how the mother gently covered her eggs and then spread sand over a wide area to obscure their location. “The experience was so moving, he cried,” says Mast, a marine biologist, of the donor. “No amount of direct mail is ever going to achieve that.” 1. What does the author want to tell us from the example of Jeffrey Brewer, the philanthropist? 2. Paraphrase Sherry Villanueva’s statement “we’re not sitting around on a fancy deck somewhere with waiters in white gloves.” (Para. 3) 3. Give some examples on the successes of the “donor trips”.

问题:问答题Practice 1 Our feverish planet badly needs a cure. It was probably always too much to believe that human beings would be responsible stewards of the planet. Yet make a mess we have. If droughts and wildfires, floods and crop failures, collapsing climate-sensitive species and the images of drowning polar bears didn’t quiet most of the remaining global-warming doubters, the hurricane-driven destruction of New Orleans did. This past year was the hottest on record in the US. The deceptively normal average temperature this winter masked record-breaking highs in December and record-breaking lows in February. That’s the sign not of a planet keeping an even strain but of one thrashing through the alternating chills and night sweats of a serious illness. A crisis of this magnitude clearly calls for action that is both bottom-up and top-down. Though there is some debate about how much difference individuals can make, there is little question that the most powerful players— government and industry—have to take the lead. Still, individuals too can move the carbon needle. Cleaning up the wreckage left by our 250-year industrial bacchanal will require fundamental changes in a society hooked on its fossil fuels. Beneath the grass-roots action, larger tectonic plates are shifting. Science is attacking the problem more aggressively than ever. So is industry. So are architects and lawmakers and urban planners. The world is awakened to the problem in a way it never has been before.

问题:问答题Passage 2 A new form of cloning to provide every baby with an embryonic “twin”, from which spare body parts could be grown and life threatening diseases treated is expected to be approved within weeks by senior government advisers on medical ethics. If their report is accepted by ministers, it would mean that Britain—which 20 years ago pioneered the test tube baby and last year produced Dolly, the world’s first cloned mammal—could be the first to clone a human embryo. A working party from the Human Fertilisation and Embryology Authority (HFEA) and the Human Genetics Advisory Commission is expected to come down firmly against reproductive cloning, the process of replicating a living human being. It is expected to recommend government support of so called stem ceils. Stem cells are extracted and used to grow spare parts, treat diseases such as Alzheimer’s and Parkinson’s or address the debilitating effects of cancer, strokes and heart attacks. Dr Austin Smith, the scientist likely to be granted the first licence for the work, said that within the next 12 years it would be routine for every baby to have an embryonic clone. “All it takes now is financial investment,” said Smith, director of Edinburgh University’s centre for genome research. The crucial discovery of embryonic stem cells, from which skin, bone, muscles, nerves and vital organs grow, was made earlier this month by scientists in America. In a submission to the HFEA, Smith said that in order to isolate these cells it is only necessary for the embryo to develop in the laboratory for six days, well within the 14-day limit of current regulation. The cells would then be grown and manipulated to make anything from blood or brain cells to tissue for repairing damaged organs and, ultimately, parts that could be transplanted without fear of the host body rejecting them. The development is likely to meet strong opposition from the church. Dr Donald Bruce, Director of the Society, Religion and Technology Project of the church of Scotland Said that creating an embryo in the knowledge that it would then be destroyed was “very disturbing” to most people. Father Paul Murray, secretary to the Catholic bishops joint bio-ethics committee, said that whatever the potential benefits, it should be regarded as “intrinsically evil” because the research depended on the use of foetal material. However, Professor Christine Gosden, professor of genetic medicine at Liverpool University, one of the four senior government advisers on the cloning sub-committee, said there would be no opportunity for abuse. For many years, patients with Parkinson’s disease who did not respond to drugs have been treated with brain cells extracted from aborted foetuses, a practice approved by a committee led by the Rev Dr John Polkinghorne, the prominent ethicist. Gosden said the arguments for the use of aborted foetal cells and therapeutic cloning were similar: “Before you have a disease, it is easy to say, ‘I would not use cells derived from a foetus’, but if you suffer from that disease, and that is your only hope, your approach can be quite different.” 1. What is the new form of cloning discussed in the passage? What is the purpose of such cloning? 2. Summarise the different views on embryo cloning discussed in the passage. 3. Explain the statement “All it takes now is financial investment.” in para. 6. 4. What is the significance of the discovery of embryonic stem cells?
