    12．All people need to sleep．Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life．Not only is the quantity of sleep important，but also the quality of sleep．
        Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment．One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep．If your bedroom also functions as a command station for your life and work，the likelihood of your sleeping being poor is rather high．Bedrooms should be designed，decorated and used for sleep mainly．TVs，computers and other things should not be in your bedroom if at all possible．
        Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness．Avoid hot food，caffeine，sugar and alcohol at least 4 to 6 hours before your sleep time．Develop a regular exercise program．Proper exercise and nutrition will help improve sleeping patterns．However，avoid exercising 2 hours before sleeping，since this may stimulate your body and make sleeping more difficult．
       Establish a pre-bedtime rule that will help you focus on sleep．You can try deep thought，reading or deep breathing and relaxation．Your bedtime rule should be yours．Do not worry about it fitting into a specific category．Do what is best for you．
    Things such as room temperature，noise and light levels and even your bed mattress（床垫） can have a lot of effect on the quality of sleep that you experience．Block out distracting noises and lights．You are in your bedroom to sleep and not be distracted by environmental interferences．

    2．A sick little girl is being kept alive thanks to her best friend-a dog who carries her oxygen tank on his back．Alida's faithful dog companion Mr Gibbs has been specially trained to shepherd the three-year-old，who breathes through a tube most of the time．He follows her closely as she plays in her family's ten-acre land in Louisville，uses the slide or even rides her bike．

    3．A glass a day keeps obesity at bay．Alcohol has always been thought to cause weight gain because of its high sugar content，but new research suggests a glass a day could form part of a diet．Looking at past studies they found that，while heavy drinkers do put on weight，those who drink in moderation can actually lose weight．
    A spokesman for the research team at Navarro University in Spain says，"Light to moderate alcohol intake，especially of wine，may be more likely to protect against，rather than promote，weight gain"．The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions，particularly that current data do not clearly indicate if moderate drinking increases weight．
    Boston University's Dr．Harvey Finkel found that the biologic mechanisms（生物学机制） relating alcohol to changes in body weight are not properly understood．His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes（糖尿病），which relate to increasing obesity．Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers．
    The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat，and that this process could explain the differences in its effects from those of other foods．They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks，taking into consideration drinking patterns and including the past tendency of participants to gain weight．
    For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one's risk of becoming obese．What's more，a study three years ago suggested that resveratrol，a compound present in grapes and red wine，destroys fat cells．

    66．The passage is mainly for thoseD．
    A．who produce wine                     
    B．who are eager to lose weight
    C．who go on a diet                      
    D．who have a drinking habit
    67．The underlined phrase"in moderation"in the first paragraph meansA．
    A．properly          
    B．carefully         
    C．excitedly          
    D．frequently
    68．Why has alcohol been thought to cause weight gain？B
    A．Because its calories are stored in fat．
    B．Because it is rich in sugar．
    C．Because it changes drinking patterns．
    D．Because it increases the risk of diabetes．
    69．What can we learn from the passage？C
    A．The specific roles of different types of alcoholic drinks are very clear．
    B．Resveratrol is proved to increase the risk of becoming fat．
    C．The research found moderate drinking has a strong protective effect．
    D．Current data clearly show that moderate drinking increases weight．
    70．What is most likely to be discussed in the paragraph that follows？B
    A．How to do some easy experiments．
    B．How to prove the finding mentioned above．
    C．How to make wine in a healthy way．
    D．How to reduce the calories contained in wine．

    20．Spending hours playing violent video games prevents teenagers from their moral growth，a study has found．It is thought that regular touch to violence and lack of contact with the outside world makes it harder for them to tell right from wrong．They also struggle to trust other people，and see the world from their viewpoints．
        Researchers from Brock University in Ontario found that those who spend more than three hours each day in front of the screen are particularly unlikely to have developed the ability to empathise（同情）．
        The Canadian researchers surveyed 109 boys and girls，aged 13 and 14，about whether they played video games，which games they liked，and how long they spent playing them．Their findings found that 88 percent of teens said they played games，and more than half admitted to playing games everyday．Violent games were among the most popular．
        The teenagers also filled in a questionnaire designed to measure their moral development．For example，they were asked how important it is to save the life of a friend．
        Previous studies have suggested that a person's moral judgement goes through four phases as they grow from children and enter adulthood．By the age of 13 or 14，scientists claim young people should be entering the third stage，and be able to empathise with others and take their viewpoints into account．The research found that this stage appeared to be delayed in teenagers who regularly played violent video games．
        It is also thought that teenagers who play games regularly did not spend enough time in the real world to learn to take other's thoughts into consideration．Researcher Mirjana Bajovic said："The present results indicate that some teenagers；who spent three or more hours a day playing violent video games，are deprived of such opportnnities．"Writing in the journal Educational Media International．the researchers added："Touch to violence in video games may influence the development of moral reasoning because violence is not only presented as acceptable but is also justified and rewarded．"
        They concluded that rather than trying to enforce an‘unrealistic'ban on the games，parents and teachers should encourage teenagers to do charity work and take up after-school activities．

    61．What would be the result of playing violent video games？D
    A．Making teens easy to get along with．
    B．Helping teens make more good friends．
    C．Causing teens easier to tell right from wrong．
    D．Getting teens hard to take others into consideration．
    62．Why did the Canadian researchers carry out the studies？B
    A．To discuss how to save the life of a friend．
    B．To measure teenagers'moral development．
    C．To enrich teenagers'awareness of social life．
    D．To develop teenagers'ability to communicate．
    63．What call we know from the words of Mirjana Bajovic？A
    A．Vio1ent games cost teens social experiences in real life．
    B．Playing games regularly will improve teens'intelligence．
    C．Playing games inspires teens to develop fast．
    D．Playing games makes teens help others．
    64．What can be inferred from the text？D
    A．Parents and teachers should let teens go online．
    B．Playing video games should be forbidden among teens．
    C．Game designers should be kindly treated and rewarded．
    D．Teens should be encouraged to do more meaningful things．
    65．Which of the following would be the best title of the text？A
    A．Violent video games affect teenagers'moral development
    B．Vio1ent video games delay teenagers'physical growth
    C．Violent video games should be forbidden among teenagers
    D．Violent video games reduce teenagers'chance in the real world．

    7．"Drink your milk．It is good for you!"You've probably heard that many times，and it is true．Milk contains calcium，which is a necessary nutrient for keeping bones and teeth healthy and strong．The US government even requires milk as part of the National School Lunch Program，saying that students should drink one cup of fat-free milk at each meal．
    Last Thursday，however，a group of doctors asked the government to remove the lunch program．The Physical Committee for Responsible Medicine says，"Milk is high in sugar，high in fat and high in animal protein，"all of which have negative effects on health．The PCRM says there were better and healthier ways to get calcium such as eating beans，broccoli，cereals and tofu．Orange juice and soymilk that have calcium added to them also supply the nutrient．"One of the only reasons people talk about dairy，or promote it at all，is because it is going to help build strong bones．"says Dr．Neal Bamard，president of the PCRM．But milk may not be the best way to get calcium your body needs．
    Of course，calcium is important for health bones and teeth，but there are other things that affect your bone strength，such as genes，how much vitamin D you take in and getting an hour's worth of exercise every day．
    Some nutritionists disagree with the idea that milk isn't important．Keri Gans，a dietitian，says，"I think it is irresponsible to take this beverage that children enjoy，especially among those who are unable to meet their nutrient needs for the day，and remove it from lunch time．"
    The US government is studying the request of the PCRM，but a decision may be a one way to take off．Meanwhile，Marion Nestle，a professor at New York University，put it best："Milk demonstrably has nutrients．Other foods have the same nutrients．It's just a food．Like other foods，too much might be a problem．"
    29．Why does the US government ask students to drink one cup of milk at lunch time？
    D
    A．They have been told many times．
    B．They have taken the PCRM's advice．
    C．Fat-free or low-fat milk is less expensive．
    D．Milk helps build students'strong bones．
    30．Which of the following opinions does the PCRM support？A
    A．Milk is harmful to students'health．
    B．Students should drink more milk each day．
    C．Orange juice is higher in calcium than milk．
    D．Milk is the best way to get calcium．
    31．The underlined word"beverage"in Paragraph 4 most probably meansC．
    A．gene        B．idea       C．milk       D．lunch
    32．What does the above text mainly talk about？D
    A．The best way to get the most calcium．
    B．The connection between milk and health．
    C．Different opinions about the importance of milk．
    D．Whether to take milk off the school-lunch menu．

    17．They already guide blind and disabled people； now dogs are to be trained to help people with dementia（痴呆） or Alzheimer's．Alzheimer's can make people confuse night and day or forget basic things such as washing or drinking enough water．
        The dogs will be trained to respond to sound triggers（触发器） in the home that cause them to perform tasks．The duties will include reminding their owners to take medicine，as well as encouraging them to eat，drink and sleep regularly．
        The idea was developed by design students at the Glasgow School of Art and will now be put into practice by Alzheimer's Scotland and Dogs for the Disabled．The first dogs will be distributed to four Scottish couples，where one of the partners is in the early stages of dementia．Some 670，000 people in Britain have dementia and one in three over 65s will develop the condition．By 2021 this is expected to rise to one million．
        Joyce Gray of Alzheimer's Scotland said，"People in the early stages of dementia are still able to live a relatively normal life，and dogs help to maintain routine．"Another advantage of using the pets as companions is that dogs can give them a sense of silent support and companionship．Ms Gray said，"The evidence is that people may forget familiar faces but not pets．It's such a strong bond that people often remember them longest．People don't need to communicate verbally （言语地） but they can still interact．You can have a speechless bond．"
        Helen McCain，director of Dogs for the Disabled，said，"People with dementia often forget to take the medicine．If a dog presents them with a bag with pills in it there's a greater chance of them taking it．The dog would also encourage the owner to take them out for walks，ensuring they keep exercising and interacting with other people．"
    32．In Britain people with dementiaA
    A．are likely to increase in number    
    B．are mostly over 65 years old
    C．will be trained to respond to sound triggers    
    D．will be able to live a relatively normal life
    33．The dogs are taught to perform tasks byD．
    A．making some sound signals  
    B．communicating with the patients
    C．reminding the patients by barking   
    D．reacting to some sound triggers
    34．What does the underlined word"them"in Paragraph 4 refer to？C   
    A．Faces．          B．Triggers．      C．Pets．           D．Companions．
    35．What is mainly talked about in the passage？B
    A．The idea of dementia dogs was developed by students．
    B．Dogs are trained to assist Alzheimer's patients．
    C．British people with Alzheimer's are in poor condition．
    D．The dementia dogs perform most duties of a doctor．
