    A．calculateB．concludeC．conveyD．convince

    分析 尽管科技不断发展，科学家们仍然无法计算出何时会有大地震．

    解答 答案：A
    该题考查动词意义辨析，calculate意为"计算、估计"，conclude意为"推论、得出结论"，convey意为"传递、传达"，convince意为"使相信、说服"，由让步状语从句Despite the rapid progress in science and technology"尽管科技不断发展"可知，主句要表达的意思应为：科学家无法"准确"确定何时会有地震，所以应用calculate来表示"准确计算出、准确确定"，故选A．

    点评 点评：考查动词及动词搭配辨义时，要准确掌握每个动词或搭配含义，并根据题干含义或逻辑关系选择正确答案．

    14．There's nothing like a good night's sleep-but what does that really mean？It turns out that the answer depends not only on your age，but also on your lifestyle．Some people are productive and happy with fewer hours of sleep，while others need more．Still，experts can determine guidelines that work for most people．The National Sleep Foundation researched the topic and gave new recommendations this week．The foundation acknowledges that sleep needs will vary-lifestyle and stress should be taken into consideration-but their recommendations offer a general guideline．For example，teenagers （ 14-17 years old） ne 8-10 hours，sleep every day．
    To create the recommendations，some sleep and medical experts reviewed 312 articles from journals published during the last decade．This is the first time that any professional organization has developed age-specific recommended sleep durations based on a systematic review of the world scientific literature．
    A lack of sleep can be linked to weight gain，because that causes an increase in appetite，according to the foundation．It can also have serious consequences on the brain．People who d o not get enough sleep are at increased risk for depression，and can endanger others．Those that become sleepy while driving，for example，risk both their lives and the lives of those around them．
    Researchers also have found in the past that too much sleep can have negative effects．Low socioeconomic status and depression reportedly are significantly associated with longer sleep．However，experts nowadays find that research on oversleeping is still unconvincing and needs more attention．Currently，there is no strong evidence that sleeping too much has health consequences．There is，however，laboratory evidence that short sleep durations of four to five hours have negative consequences．We need similar laboratory studies to determin e whether long sleep durations result in physiological changes that could lead to disease before we make any recommendations against sleep extension．
     
    41．Which is TRUE about sleeping time？A
    A．The time you need for sleep is related to your state of mind．

    A．lose some weight                                       
    B．eat more food  
    C．dream during their sleep

    4．Among all the fast growing science and technology，the research of human genes，or biological engineering as people call it，is drawing more and more attention now．Sometimes it is a hot topic discussed by people．
    The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with，such as cancer and heart disease．Every year，millions of people are murdered by these two killers．And to date，doctors have not found an effective way to cure them．But if the gene technology is applied，not only these two diseases can be cured completely，bringing happiness and more living days to the patients，but also the great amount of money people spend on curing their diseases can be saved，therefore it benefits the economy as well．In addition，human life span（寿命） can be prolonged．
    Gene technology can help people to give birth to healthy and clever children．Some families，with the English imperial family being a good example，have hereditary（遗传的） diseases．This means their children will for sure have the family disease，which is a great trouble for these families．In the past，doctors could do nothing about hereditary diseases．But gene technology can solve this problem perfectly．The scientist just need to find the wrong gene and correct it，and a healthy child will be born．
    Some people are worrying that the gene research can be used to manufacture human beings in large quantities．In the past few years，scientists have succeeded in cloning a sheep，therefore these people predict that human babies would soon be cloned．But I believe cloned babies will not come out in large quantities，for most couples in the world can have babies in very normal way．Of course，the government must take care to control gene technology．

    66．What does"these two killers"in the second paragraph refer to？C
    A．Gene technology and another treatment of the two diseases．
    B．The two murderers who killed the cloned baby．
    C．The two diseases of cancer and heart disease．
    D．Hereditary diseases and cancer．
    67．What's the main idea of the third paragraph？A
    A．How gene technology can be applied in the field of treating hereditary diseases．
    B．Gene technology can be used to clone human babies．
    C．Gene technology can help people to give birth to a baby．
    D．Gene technology can help the English imperial family out．
    68．In what way gene technology can help to treat hereditary diseases？B
    A．Using gene technology，people with hereditary diseases can have more living days．
    B．Using gene technology，the scientist finds the wrong gene and corrects it．
    C．Using gene technology，human babies can be cloned．
    D．Doctors can cure cancer and heart disease with the help of gene technology．
    69．What is the main purpose of writing this passage？A
    A．Expressing the writer's idea that gene technology will benefit people．
    B．Telling people the disadvantages of gene technology．
    C．Telling the readers that gene technology will not benefit people．
    D．Explaining that gene technology will also do harm to the humanity．

    11．Going on holiday not only makes you feel good while you're there，you also gain the health benefits for months，new research shows．
    Jetting off to destinations such as the Maldives cuts your blood pressure，helps you sleep better and bounce back from stress，it found．The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed．Experts say workers should always take their full holiday entitlement（权利）each year，but as many as one in three don't．

    7．If you're thinking about reaching for another biscuit to get you through the working day，think again．Eating unhealthy snacks at your desk makes you pile on almost half a stone a year，a survey has revealed．The waistlines of women suffer the most，with the average female putting on 6lb 3oz-the equivalent of a whole dress size-while men see their weight increase by 5lb 2oz．
    The report into our eating habits found that，on average，we eat at least two snacks a day，with 30 per cent of us tucking into three or more．Women admit eating more than men，with a further 13 per cent of ladies scoffing four or more snacks a day．The research，by The Village Bakery，found biscuits are the most common vice，with 42 per cent regularly opening a pack，closely followed by chocolate （38 per cent），crisps （32 per cent） and cakes （13 per cent）．
    And office workers are worse than most．Cakes and biscuits brought into work by colleagues are one of the main temptations office staff give in to．In addition，33 per cent admit reaching for nibbles to cope with stress and 22 per cent say they need a sugar rush to perk them up in the afternoon．
    Simon Staddon，of The Village Bakery，said："We were aware time-poor office workers can find it difficult to easily access a nutritional lunch．But we were really shocked by the extent to which‘quick fix'lunches are affecting weight gain and general wellbeing．Popular mid-afternoon pick-me-ups such biscuits，chocolate and cakes are high in calories，fat and full of sugar，all of which affect your blood sugar levels and ultimately lead to weight gain．"
    The survey of 2，000 British men and women suggests we are often ashamed of our unhealthy eating．Twenty-four per cent of Britons admit lying about how many snacks they eat with 33 per cent of women lying，compared to 20 per cent of men．Unfortunately，it's not as if we are likely to do anything positive to counteract the sweet treats．

    61．According to the passage，women usually put weight on firstD

    A．Colleagues eat them to save money．
    B．Staff use them to cope with their lunch．
    C．Colleagues often bring them to office．
    D．Bosses invite staff to eat them．
    63．Why do office workers eat a"quick fix"lunch？D
    A．Because it has much of nutrition．
    B．Because it has little effect on weight gain．
    C．Because it has little effect on general wellbeing．
    D．Because they have short time to have their lunches．
    64．It can be inferred that British women areB．
    A．less likely to lie on snacks than men       
    B．more likely to lie on snacks than men
    C．more ashamed of eating snacks than men
