"There is (53) Cook in the Australian Museum," museum collection manager Jude Philip said not long ago in announcing the DNA evidence that the arrow was not made of Cook’s bone. But that will not stop the museum from continuing to display the arrow in its (54) "Uncovered: Treasures of the Australian Museum," which (55) include a feather cape presented to Cook by Hawaiian King Kalani ’opu’u in 1778. Cook was one of Britain’s great explorers and is credited with (56) the "Great South Land," (57) Australia, in 1770. He was clubbed to death in the Sandwich Islands, now Hawaii. The legend of Cook’s arrow began in 1824 (58) Hawah’an King Kamehameha on his. deathbed gave the arrow m William Adams, a London surgeon and relative of Cook’s wife, saying it was made of Cook’s bone after the fatal (59) with islanders. In the 1890s the arrow was given to the Australian Museum and the legend continued (60) it came face-to-face with science. DNA testing by laboratories in Australia and New Zealand revealed the arrow was not made of Cook’s bone but was more (61) made of animal bone, said Philp. However, Cook’s fans (62) to give up hope that one Cook legend will prove true and that part of his remains will still be uncovered, as they say there is evidence not all of Cook’s body was (63) at sea in 1779. "On this occasion technology has won," said Cliff Thornton, president of the Captain Cook Society, in a (64) from Britain. "But I am (65) that one of these days ...one of the Cook legends will prove to be true and it will happen one day."

People who slept only hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night’s rest may not need to set aside more than g hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep -- for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bed. "It stands to reason that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake," he said. To get a good night’s rest, people may not need to ______.A fall asleep again.B become more energetic the following dayC sleep less than 7 hoursD confirm those serious consequencesE suffer sleep problemsF sleep more than 8 hours

And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluated, he said. "Nobody’s going to drop dead overnight but we should be asking for more scientific information," Robert Bell said at a conference on the health effects of low-level radiation. (46) . A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effects on humans from electromagnetic radiation. According to Robert Bell, there axe 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day. (47) . As well, there are 2,000 transmitter towers around Australia, many in high density residential areas. (48) The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby. Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child cam centres, hospitals, sports playing fields and residential areas with a high percentage of children. (49) . He adds that there is also evidence that if cancer sufferers ale subjected to electromagnetic waves the growth rate of the disease accelerates. (50) . According to Robert Bell, it is reasonable for the major telephone companies to fund it. Besides, he also urges the Government to set up a wide-ranging inquiry into possible health effects.A He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults.B By the year 2000 it is estimated that Australia will have 8 million mobile phones: nearly one for every two people.C "If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised," he said.D Then who finances the researchE For example, Telstra, Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community.F The conclusion is that mobile phones brings more harm than benefit.
第三篇 Light Night, Dark Stars Thousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificial lights to block the view. people can see more than 14,000 stars in the sky, says Dennis Ward. an astronomer with the University Corporation for Atmospheric Research (UCAR) in Boulder. Colo. But when people are surrounded by city lights, he says, they’re lucky to see ISO stars. If you’ve ever driven toward a big city at night and seen its glow from a great distance, you’ve witnessed fight pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates the night sky. This haze of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult. Dust and particles of pollution from factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another." Ward says, "that city will suffer the effects of light pollution on a much greater scale." Hazy skies also make it far more difficult for astronomers to do their jobs. Cities are getting larger. Suburbs are growing in once dark. rural areas. Light from all this new development is increasingly obscuring the faint light given off by distant stars. And if scientists can’t locate these objects, they can’t learn more about them. Light pollution doesn’t only affect star visibility. It can harm wildlife too. It’s clear that artificial light can attract animals, making them go off course. There’s increasing evidence, for example, that migrating birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr., a scientist at Clemson University in South Carolina. "When light occurs at night," he says, "it has a very disruptive influence." Sometimes birds fly into lighted towers, high-rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year. Which of the following is closest in meaning to the title "Light Night, Dark Stars"
