    　　Dr．Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind．But he had no idea at the time that 12-year-old Ray had the ability to become his partner in cancer research．

    　　Ray's parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner(吸尘器)．When he was ten, he speedily constructed the family color television from a kit．Later, he succeeded in assembling(组装)a complex stereo system after two experts had failed to do the job．

    　　When Ray was ten, he convinced his parents to buy him a computer．In a short time, Ray was able to do amazing things with the computer．Ray shared his enthusiasm for computers with Dr．Tisman, who used a computer for his research．The two discussed computers and medicine frequently．Amazingly, Ray understood the biology and chemistry related to Dr．Tisman's medical research without any previous instruction．

    　　Ray then worked with Dr．Tisman after school．He helped conduct research with the equipment and kept it in working order．The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins．Ray analyzed patient test results by computer, while Dr．Tisman handled all patient contact．Together, they came up with solid research that helped advance cancer treatment．

    　　In 1988, 14 - year - old Ray went with Dr．Tisman to a meeting of the American Federation for Clinical Research(AFCR), where Ray presented their initial research findings．Using terminology(术语)beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients．

    　　A year later, Ray returned to the meeting to update the findings of his and Dr．Tisman's research．By then, he had become well - known for his devotion to finding cures for sick patients．Stories about him appeared in hundred of newspapers around the world．He appeared on television newscasts and talk shows．

    　　Ray continued to spend most free hours working with Dr．Tisman．The two began studying the effects of vitamins on babies inside the womb(子宫)．However, Ray's main interest remained cancer treatment, and he continues his research today．

    　　Increasing fluid intake(摄入量)by about a liter per day appears to have no negative effects on healthy older men．Dutch researchers report．

    　　Dr．Mark G．Spigt of Maastricht University and his colleagues note that older people are often dehydrated(脱水)，partly because their sensation of thirst may be slow．On the other hand, the elderly can easily become overly hydrated, because their kidneys(肾)tend to work less efficiently．Keeping extra water reduce the level of sodium(钠)in the body, which can have serious consequences．

    　　To investigate the general effects of increased fluid intake, the researchers examined data from a study involving 141 healthy men aged between 55 and 75．In random(随意的)order they were either advised to increase their water intake by a liter and a half per day, or were given a spoonful of syrup(糖浆)per day．

    　　After 6 months, the men urged to drink more water had managed to boost their daily fluid intake by an average of about a liter per day．There were no significant differences between the two groups in blood pressure or sodium level．

    　　The researchers thus concluded that the advice to increase fluid intake had no negative effects．

    　　Summing up, Spigt added,“It seems unreasonable to worry about the harmful effects of drinking extra water, he warned,”This does not mean that one can drink too much．Extreme intakes of water-more than 10 liters–can be harmful．

    tell us the result of a research

    (2)

    According to Spigt and his colleagues, the elderly are often dehydrated ________．

    [　　]

    A．

    because their kidneys can’t work properly

    B．

    because water can reduce the level of sodium in the body．

    C．

    because they need less water than before．

    D．

    partly because their feeling of thirst may be slow．

    (3)

    　　Would you eat a ready meal from the fridge rather than cook from scratch?Have you been doing internet shopping rather than going to the stores?What can’t you be bothered to do?

    　　A study into how lazy British people are has found more than half of adults are so lazy they’d catch the lift rather than climb two flights of stairs．

    　　Just over 2000 people were quizzed by independent researchers at Nuffield Health, Britain’s largest health charity．The results were astonishing．

    　　About one in six people surveyed said if their remote control was broken, they would continue watching the same channel rather than get up．

    　　More than one third of those questioned said they would not run to catch a bus．Worryingly, of the 654 respondents with children, 64％ said they were often too tired to play with them．

    　　This led the report to conclude that it’s no wonder that one in six children in the UK are classified as obese(very fat)before they start school．

    　　Dr Sarah Dauncey, medical director of Nuffield Health, said：“People need to get fitter, not just for their own sake, but for the sake of their families, friends and evidently their pets too．”

    　　“If we don’t start to take control of this problem, a whole generation will become too unfit to perform even the most rudimentary of tasks．”

    　　And Scotland’s largest city, Glasgow, was shamed as the most inactive city in the UK, with 75％ surveyed admitting they do not get enough exercise, followed closely by Birmingham and Southampton, both with 67％．

    　　The results cause serious challenges for the National Health Service, where obesity-related illnesses such as heart disease and cancer have been on a steady increase for the past 40 years and are costing billions of pounds every year．

    (1)

    What causes children in the UK to be obese?

    　　Watching 3D films such as Avatar could give some viewers headaches, experts have warned．

    　　The success of James Cameron's science-fiction blockbuster(卖座的大片), which has already taken more than ＄1 billion(￡600 million)at the box office, is fuelling a surge in popularity for three-dimensional movies and new 3D television sets．

    　　But prolonged viewing may result in an aching head, according to Dr Michael Rosenberg, an ophthalmology(眼科学)professor at Northwestern University Feinberg School of Medicine in Chicago．

    　　He said："There are a lot of people walking around with very minor eye problems, for example a minor muscle imbalance, which under normal circumstances the brain deals with naturally．"

    　　Watching a 3D movie confronts viewers with an entirely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," he said．

    　　Dr Deborah Friedman, a professor of ophthalmology and neurology(神经学)at the University of Rochester Medical Center in New York, said："If your eyes are a little off to begin with then it's really throwing a whole degree of effort that your brain now needs to exert．This disparity for some people will give them a headache．"

    　　Experts say there are no studies tracking how common it is to get a headache after watching a 3D film．

    　　Rick Heineman, a spokesman for RealD, which provides 3D equipment to cinemas, said headaches and nausea were the main reasons 3D technology never took off before．

    　　But he said new digital technology addresses many of the problems that had previously caused sore heads．

    (1)

    What can we learn from what Dr Michael Rosenberg said?

    [　　]

    A．

    A lot of people prefer walking around with very minor eye problems to sitting silently watching 3D films．

    B．

    The brain can deal with very minor eye problems under normal circumstances naturally．

    C．

    A lot of people haven’t got very minor eye problems when viewing films under normal circumstances．

    D．

    People come into very minor eye problems and a minor muscle imbalance when watching 3D films．

    (2)

    What does the underlined word “prolonged” in the 3rd paragraph mean?

    A．

    continuous

    B．

    constant

    D．

    long-time

    (3)

    According to the passage, which of the following is TRUE?

    [　　]

    A．

    It has taken less than ＄1 billion to make the popularity of three-dimensional movies and new 3D television sets．

    B．

    Watching a 3D movie leaves viewers confronted with an entirely new sensory experience．

    C．

    There are studies tracking how common it is to get a headache after watching a 3D film．

    D．

    Rick Heineman said that 3D technology would never take off headaches and nausea in future．

    (4)

    What’s the main idea of the passage?

    [　　]

    A．

    The expert warns the readers not to watch 3D films because of resulting in an aching head．

    B．

    New digital technology gives viewers headaches and eye problems．
