    19．Leaders of the World Health Organization say they are concerned about the air quality and health efiects on citizens during a recent outbreak of heavy pollution in Beijing．Still，they said they were unsure of the exact amount the air pollution takes on any person's body，casting doubts on local reports tying the area's dirty air to particular cases of illness．
       Speaking at a briefing（情况介绍会）on Tuesday，the WHO's Western Pacific regional director，Shin Young-Soo，cited（列举）reports about poor air quality causing lung cancer in recent weeks．
    "The WHO is skeptical of the information，"she said．"We're cautious of whether the illness is related to air po11ution．We know it has an impact on health，but we don't know how much．"
        The officials didn't cite particular reports．The comments follow a number of articles since late last year connecting some cases of diseases like lung cancer with pollution，．including one in November regarding an 8-year-old girl．
       The health impact of Beijing's gray skies has been on the minds of many over the past week．Local authorities on Tuesday preserved an orange alert（警报）一the city's second highest pollution-warning level-and again warned people to stay indoors．Experts widely agree that small particulates（颗粒） known as PM2.5 carry significant short-and long-term health risks，particularly with children．Other studies find a certain link between pollution and shorter life spans．
    Chinese state media have noted a rise in cancer levels in Beijing，without specifying（具体说明）whether the new cases are the main result of pollution，smoking，other sources or some combination．
    Bernhard Schwartlander，the organization's China chief，said he is concerned and has been in contact with national authorities．"There is no easy solution，"Dr．Schwartlainder said，adding that solving the problem requires managing industry and the economy．WHO leaders advised citizens．to stay indoors and limit exposure to the harmful particulates．When asked if wearing a face mask has any proven efficacy in preventing health effects of air pollution，Dr．Schwartlainder said，"Whatever you do，it's better than nothing．"

    68．We can learn from the passage thatA．
    A．in case of an orange alert，we had better not go outside
    B．the case of the girl with lung cancer was little'linked to air pollution
    C．cancer levels in Beijing are rising due to heavy air pollution
    D．it is widely agreed that pollution shortens life spans very slightly
    69．According to Dr．Schwartlander，the ways to solve the problem includeC．
    A．contacting the national authorities     
    B．being exposed less to harmful particulates
    C．managing the enterprise and economy  
    D．preventing health effects of pollution
    70．What would be the best title of this passage？D
    A．The dangers of heavy pollution
    B．The impacts of pollution on health
    C．The importance of protecting the environment
    D．The uncertainty of relationship between pollution and health．

    分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了世界卫生组织尚不确定雾霾对人体健康的具体危害，我们知道雾霾对人们的身体健康有影响，但我们不确定有多大的影响，因此我们只能尽量减少接触污染严重的环境，不管采取哪种措施，都比什么都不做要好．

    解答 68．A．细节理解题．根据文章第五段"Local authorities on Tuesday preserved an orange alert（警报）一the city's second highest pollution-warning level-and again warned people to stay indoors"，当地有关部门周二维持橙色预警（污染警报级别第二级），并且再度警告人们留在室内；故选A．
    69．C．细节理解题．根据文章最后一段．"There is no easy solution，"Dr．Schwartlainder said，adding that solving the problem requires managing industry and the economy，可知解决方案为管理行业和经济；故选C．
    70．D．推理判断题．通读全文，可知文章主要再讲无法判断环境污染和健康的关系，因此最佳标题为污染与健康关系的不确定性；故选D．

    点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．

    18．Losing weight comes with a lot of health benefits-including making your brain sharper．
    Yes，it turns out that overweight may damage cognitive functions such as memory and attention．There have been few studies of overweight and cognitive functioning，possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance．Losing weight，therefore，may help improve these mental functions，according to a new research led by John Gunstad，assistant professor of psychology at Kent State University．
    Growing evidence suggests that being fat is linked to cognitive deficits（缺陷）．So Gunstad and his team guessed that losing weight might improve mental function．For their study，they measured memory and attention in a group of l 50overweight participants，some of whom had some kind of operation for weight loss and some did not．All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study，and again 12weeks later．To begin with．about 24%of the patients showed damaged learning and 23%showed signs of poor memory when tested．At the end of the study，those who had lost weight after operation improved their scores into the average or above average range for cognitive functions．Scores for the volunteers who didn't lose weight dropped even further．
    The study helped Gunstad to find out whether losing weight had any effect on mental function．Now that he's seen the positive effect that weight loss can have on memory and attention，he says he will next study those who choose to lose weight by the traditional way-eating healthier and getting more active．He expects that losing weight in this way will have a similarly positive effect on the brain．"If we can improve the condition with operations，then we can probably produce the same change with behavioral weight loss as well，''he says．

    63．There is less research on overweight and cognitive functions because researchersC
    A．believe overweight only affects our body
    B．have focused on ways to sharpen people's mind
    C．do not consider overweight a main cause for low cognitive ability
    D．are clear about the relation between weight and mental functions
    64．The result of Gunstad's study shows thatB
    A．losing weight has little effect on people's memory
    B．losing weight can improve people's mental functions
    C．overweight people are likely to have psychology problems
    D．overweight people's abilities of concentration differ greatly
    65．What is Gunstad planning to prove next in his research？D
    A．Slim people are smarter than overweight people．
    B．Healthy diet is better than exercise in losing weight．
    C．Traditional ways of losing weight are better than operation
    D．Overweight people will get smarter by taking more exercise．
    66．Which of the following is the best title for the text？D
    A．Body Weight and Health              B．Losing Weight by Operation
    C．Ways to Improve Mental Functions    D．Losing Weight to Sharpen Your Mind．

    A child （57）A in this way learns his or her role through joining in the community's work：helping to dig or build，look after animals or babies---rather than through playing with water and sand in kindergarten，keeping pets （58）C playing with dolls．

    7．Since the beginning of the year，smog has covered parts of North China．In January，Beijing saw only five days without smog．The rising PM 2.5readings terrified many people，and some health experts said that whenever the smog gets serious，hospitals receive more patients suffering acute respiratory（呼吸系统）and heart diseases．
    Later，news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe．
    So the need to emphasize environmental protection while developing the economy is heard everywhere．
    Smog especially is a common concern．Like a popular online post said，air may be the only thing that is equal for everyone，despite your income or vocation．People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices，but they breathe the same air as everyone else．
    At a meeting on Monday，many Representatives have expressed their concerns about the air quality，too．One talked about his experience in Beijing．"After taking a taxi from the capital airport to my hotel，which took about an hour，I washed my nose and found the inside of my nose was black．We should ask ourselves this question：Why do we want to develop？It's for living a better life．Dirty air is definitely not a better life，"he said．
    China needs to develop its economy and invest（投资） in high-tech．Every Chinese wants a strong country．But without blue sky，clean water and safe food，the achievements in the economy will become meaningless．Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth．
    What the public wants is a strong and beautiful China．President Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China．The words have shown the central government's resolution to address the environment issue．

    41．The effect of smog doesn't includeC．
    A．the rising of PM 2.5readings
    B．more people suffering diseases
    C．the increase of people's income
    D．patients increased in hospital
    42．Why smog has become a common concern？B
    A．Because people have to pay higher prices．
    B．Because nobody can avoid it．
    C．Because we have to develop industry．
    D．Because a popular online-post discussed it．
    43．To make China stronger we have to develop economy，butB．
    A．we have to sacrifice air as the price 
    B．the dirty air is not what we want
    C．ecological progress can be ignored
    D．the smog is the only byproduct
    44．The underlined word"they"in paragraph 6refers toA．
    A．human beings
    B．other plants
    C．space technologies
    D．industrial development
    45．From the last two paragraphs we can infer thatD．
    A．high-tech can completely solve the problem of pollution
    B．space technologies should be developed in a large scale
    C．we can move to the Mars after the earth has been destroyed
    D．we must protect the environment while developing economy．

    14．Why is it so difficult to fall asleep when you are overtired？There is no one answer that applies to every individual．But many people fail to note the difference between fatigue，physical tiredness and sleepiness，the inability to stay awake．It's possible to feel"tired"physically and still be unable to fall asleep，because while your body may be exhausted，you don't feel sleepy．To fall asleep，you need enough time to relax，even if you feel fatigued．It's not so easy to simply"turn off"．According to Carl E．Hunt，director of the National Center on Sleep Disorders Research in Bethesda，Maryland，most people do not allow themselves relaxed．
    Lack of sleep complicates matters even more．Experts say adults need at least 7 to 8 hours of sleep a night to function properly．When you get less sleep than that on consecutive （连续） nights，you begin to be burdened by"sleep debt"．As sleep debt increases （and functionality decreases），your body experiences a stress response and begins to release adrenaline （肾上腺素）．Now a bad cycle has been created：You experience the feeling of being more and more tired，but your body is increasingly stimulated．"Power sleeping"for more hours on weekends is only a temporary solution．"There is no substitute for getting a good night's sleep on a regular basis，"says Hunt．
    Most of us，however，don't get the sleep we need．According to the 2002 National Sleep Foundation，Americans sleep an average of 6.9 hours per night during the week，and 58 percent of adults experience sleeplessness a few nights a week or more．

    33．The writer intends to tell usD．
    A．Americans don't get enough sleep
    B．what benefits we can get from enough sleep   
    C．lack of sleep has a bad effect on our body  
    D．why it's difficult for overtired people to fall asleep  
    34．Which of the following is NOT caused by lack of sleep？C
    A．Power sleeping．                        
    B．Sleep debt．
    C．Lack of adrenaline．                    
    D．Function badly．
    35．From the passage we can draw a conclusion that lack of sleepD．
    A．is so common that it isn't worth paying attention to
    B．doesn't matter for it can be solved by"Power sleeping
    C．can make it easy to fall asleep when one is overtired
    D．may make it difficult to fall asleep when one is overtired．

    4．Around 200 people who thought their only experience of the London 2012 Olympic Games would be minor heats of synchronized swimming （花样游泳） have received an unexpected hange to the men's 100m final because of an embarrassing ticketing mistake．
    The London 2012 Organising Committee （Locog） confirmed on Wednesday that an error n its ticket selling had led to four synchronised swimming competitions being oversold by 10，000 tickets．
    Locog and its ticket agent spent the Christmas period contacting ticket holders and offering them alternatives that included the tickets they had applied for but unsuccessful．The hanges need no additional cost．It has also offered to return any discrepancy （差额） if the n ew tickets cost less than the originals．Locog said the replacement tickets would come from a number of unsold seats across the Olympic Games and itwas doing all it could to make up the error to the fans who bought tickets．

    Thousands of ticket holders have already struck lucky，changing to tickets for major events including swimming and athletics finals，and in around 200 cases the hottest of all，the men's 100m final．Locog said the decision to award 100m final tickets was made because one of the synchronised swimming competitions was on the same afternoon as the event，August 5．
    61．As a result of the ticketing mistake，about 200 peopleA   
        A．will luckily be able to watch the men's 100m final
