    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．

    44．A．细节理解题．根据文章倒数第二段：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．可知科技还没有发展到所有都可以移居火星，若有一天人们毁坏了地球．they指代前面的all human beings，故选A．
    45．D．推理判断题．根据文章倒数第二段：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．可知我们发展经济的同时要保护环境，故选D．

    6．Nuclear power's danger to health，safety，and even life itself can be summed up in one word：radiation．
    Nuclear radiation has a certain mystery about it，partly because it cannot be detected by human senses．It can't be seen or heard，or touched or tasted，even though it may be all around us．There are other things like that．For example，radio waves are all around us but we can't detect them，sense them，without a radio receiver．Similarly，we can't sense radioactivity without a radiation detector．But unlike common radio waves，nuclear radiation is not harmless to human beings and other living things．
    At very high levels，radiation can kill an animal or human being immediately by killing masses of cells in vital organs．But even the lowest levels can do serious damage．There is no level of radiation that is completely safe．If the radiation does not hit anything important，the damage may not be serious．This is the case when only a few cells are hit，and if they are killed immediately，your body will replace the dead cells with healthy ones．But if the few cells are only damaged，and if they reproduce themselves，you may be in trouble．They can grow into cancer．Sometimes this does not show up for many years．
    This is another reason for some of the mystery about nuclear radiation．Serious damage can be done without the victim being aware at the time that damage has occurred．A person can be irradiated（辐射 ）and feel fine．then die for cancer five，ten，or twenty years later as a result．Or a child can be born weak as a result of radiation absorbed by its grandparents．
    Radiation can hurt us．We must know the truth．

    51．What is the most dangerous factor of nuclear power？C
    A．Amount       B．Quantity         C．Radiation         D．Place
    52．Which of the following statements is TRUE？B
    A．Nuclear radiation can do little harm to human beings．
    B．Nuclear radiation can do harm to human beings．
    C．Nuclear radiation can be detected by human senses．
    D．Nuclear radiation is just like common radio waves．
    53．How can nuclear radiation kill an animal？D
    A．By damaging its heart．
    B．By killing a few cells in its body．
    C．By hitting any place in its body．
    D．By killing many cells in important organs．
    54．Nuclear radiation has a certain mystery becauseA．
    A．it can do harm to a person while the victim doesn't know
    B．human beings learn its harmfulness
    C．nuclear radiation can kill a person very easily
    D．human beings have no effective machine to detect nuclear radiation
    55．If a human being is hit by nuclear radiation，he mayD．
    A．die of cancer after many years
    B．die immediately
    C．have a child who may be born weak
    D．all of the above．

    9．People who do not get enough vitamin A in their diet may develop night blindness．But in the developing world a lack of vitamin A causes much more serious harm to children．The World Health Organization links the lack of vitamin A to as many as 250.000 child deaths every year．
        One excellent source of vitamin A is found in sweet potatoes with orange flesh．Orange sweet potatoes contain high levels of beta-carotene（胡萝卜素），which our body can change into vitamin A． Experts say orange sweet potatoes specially bred （育种，培植） for growing conditions in Africa
    could help solve the lack of vitamin A there．
         But，first，more people will need to be persuaded to eat them． Jan Low with the International Potato Center，a research organization says the sweet potato needs a better image in Africa． Jan Low says，…We do have an image problem with sweet potato in general in sub-Saharan Africa． It is seen as a crop of the poor．"Ms Low explains that sweet potatoes are mainly grown by poor women to feed their families in case another crop fails． The sweet potatoes commonly grown if Africa have white or yellow flesh． But，more importantly，they are low in vitamin A．
        Jan Low took part in a project to study how best to market orange sweet potatoes to Africans．She worked on an information campaign in Mozambique and Uganda．The campaign included radio messages about the nutritional benefits of the orange sweet potato．They advertised its ability to"fight diseases，make you strong，clear your skin and make you look healthy．"In areas without radio，the campaigners spread the message through community theater．The performances included singing，dancing and storytelling．And everywhere they went，the campaigners wore orange T-shirts and hats．They even drove orange vehicles．Jan Low says the color made it easier to gain public attention．
       Dan Gustafson heads the Washington office of the United Nations Food and Agriculture Organization． He points toefforts in the past to increase the popularity of other nutritious crops． He says most of these efforts failed because organizers of the campaigns did not consider what people wanted to eat．But Mr．Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa． For one thing，except for the color，the vegetable is similar to what people already use．
    66．What does the writer want to tell us in Para． 1？B
    A． Vitamin A in food may cause night blindness．
    B． People should get enough vitamin A in their diet．
    C． The developing countries are in lack of vitamin A．

    B． Jan Low tries to persuade more people to eat orange sweet potato．
    C． The campaign aims to advertise the benefit of orange sweet potato．
    D． Fighting diseases，making you strong，clearing your skin and making you look healthy are the ability of the orange sweet potato．
    68．Jan Low works forB．

    B． the International Potato Center
    C． the government of Mozambique and Uganda
    D． the United Nations Food and Agriculture organization

    B． an information campaign in sub-Saharan area
    C． the popularity of vitamin A

    2．More than a third of the babies born this year could receive a 100th birthday message from whoever happens to be on the throne in the second decade of the 22nd century，according to figures published by the Office for National Statistics （ONS）．It forecasts that 35% of the 826，000people born in 2012will live to become centenarians．
    But a long life is not unalloyed good news．David Sinclair，head of policy and research at the International Longevity Centre UK，warned that for many the future may mean social isolation（隔离）as they live longer than friends and members of their families．
    "It is of course good news that so many more people are living longer，"he said，"but there is a big'but1．We will be older，but in worse health，and at high risk of living alone．The other problem is that we are very poor at forward planning．We deal with the problems that are under our noses，but even problems two or three years away seem quite distant enough to put off．When you're talking about forecasts for a time half a century away and more，I see no evidence that we are putting in place the measures to deal with it．"

    Women have higher life expectancies than men at every age：the likelihood of a girl born this year reaching her century is estimated to be 39%； for boys the figure is 32%．
    The estimated number of female centenarians has risen from 500in 1961to more than 10，000in 2010，a figure which is projected to reach 71，000by 2035and 276，000by 2060．
    Men are also living far longer，although their numbers are far fewer．There were an estimated 92male centenarians in 1961and just below 2，000in 2010．

    35．The under lined word centenarians probably means people whoD．

    B．live longer than their friends
    C．are in poor health

    36．From what David Sinclair said，we can learnB．
    A．he doesn't believe so many people are living longer
    B．the older we are，the more likely we are to live alone and in poor health
    C．the people who are good at forward planning are likely to live longer
    D．too distant planning is not always necessary for most of us

    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．

    17．An increase in students applying to study economics at university is being attributed to （归因于）the global economic crisis （危机） awakening a public thirst for knowledge about how the financial system works．

    Zack Hocking，the head of Child Trust Funds，said："It's possible that one good thing to arise from the downturn will be a generation that's financially wiser and better equipped to manage their money through times of economic uncertainty．"
