    What is green food? Do you enjoy green food every day? The concept of “green food” was first suggested by the Department of the Ministry of Agriculture in 1990.
    Green symbolizes life, health and energy. Nowadays, people demand healthy and fresh food. Having enough food to eat is only a basic requirement, and they need more than this. They want to enjoy unpolluted, safe and nutritious food and eat comfortably. So the government does this through a set of “from the land to the dinner table” quality controls. It requires to change China’s traditional agricultural structures and ensure the food of high quality.
    Safe vegetables refers to products without substances harmful to humans. Growing such vegetables requires no strong poisons, thus guaranteeing vegetables fresh and clean. There are strict regulations in place for even applying fertilizer(肥料). The examination of vegetables should reach the state food hygiene(卫生) standard. The following conditions for green food are regulated by the China Green Food Development Center. Firstly, products or raw materials must reach the green ecological environment standard set by the Ministry of Agriculture. Secondly, crop planting, livestock raising, fish breeding and food processing must follow green food operating procedures set by the Ministry. Products must be up to the green food hygiene standard. External packing must be pasted with national standard universal labels, special green food packing decoration and tag regulations.
    However, by now, our goal hasn’t been completely realized. When you return home with a full basket, you are still worried about whether what you have bought is green and healthy. Indeed, for the sake of our health, we still have a long way to go.

    小题1:D
    小题2:C
    小题3:A
    小题4:B

    8. 小题1:根据文章大意可知，绿色食品指的是健康食品，并不是说食品的颜色是绿色的，也不是特指蔬菜，故A项和B项错误；根据文章第三段“strict regulations in place for even applying fertilizer”，可知对绿色食品的施肥有严格的限制，并不是说不必施肥，故C项错误；根据文章第三段可知绿色食品需要经过一系列检验，故D项正确。
    9.小题2:根据文章第三段可知，绿色食品不能造成生物破坏，需要符合食品管理程序，需要达到卫生标准，故A、B、D项都符合，根据第三段最后一句话可知绿色食品的包装上需要有特殊的标志，而不是说食品本身需要有标记，故C项说法错误。
    10.小题3:根据全文可知，农业部应该负责农产品的生产，监督以及管理等，A项合适。

    Unhappy people glue（使粘牢） themselves to the television 30 percent more than happy people.
    The finding, announced on Thursday,   1  from a survey of nearly 30,000 American adults conducted between 1975 and 2006 as part of the General Social Survey.
      2  happy people reported watching an   3  of 19 hours of television per week, unhappy people reported 25 hours a week. The results held even after   4  into account education, income, age and marital status.
    In addition, happy individuals were more socially   5 , attended more religious services, voted more and    6 a newspaper more often than their less-chipper（没有精神的） counterparts.
    The researchers are not sure, though, whether unhappiness   7 more television-watching or more viewing leads to unhappiness.
    In fact, people say they like watching television: Past research has shown that when people watch television they   8   it. In these studies, participants reported that on a   9 from 0 (dislike) to 10 (greatly enjoy), TV-watching was nearly an 8.
    But perhaps the high from watching television doesn't  10  .
    "These conflicting data  11  that TV may provide viewers with short-run   12 , but at the expense of long-term malaise(精神欠爽)," said researcher John Robinson, a sociologist at the University of Maryland, College Park.
    In this case, even the happiest campers could turn into Debbie-downers if they continue to   13 at the TV. The researchers suggest that over time, television-viewing 14  push out other activities that do have more lasting   15 . Exercise and sex come to mind, as do parties and other forms of socialization known to have psychological benefits.
    Or, maybe television is simply a refuge(慰藉物) for people who are already  16 .
    "TV is not judgmental 17 difficult, so people with  18 social skills or resources for other activities can engage in it," Robinson and UM colleague Steven Martin write in the December issue of the journal Social Indicators Research.
    They add, "  19  , chronic unhappiness can be socially and personally debilitating（使人衰弱的） and can interfere with work and most social and personal activities, but even the unhappiest people can click a remote and be passively   20 by a TV."
    The researchers say follow-up studies are needed to tease out the relationship between television and happiness.

    It came with devastating force,a natural disaster of strange intensity that shocked the world and killed tens of thousands.The waters have now receded,but disease and food and water shortages trouble a number of countries around the Indian Ocean.Millions of survivors face serious problems.
    The number of survivors in need of food aid after the Indian Ocean disaster has climbed to 5 million people.They stretch from Somalia to Thailand,and the figure could rise further,the United Nations has said.
    Relief teams hope to reach all of the estimated 700 000 hungry in Sri Lanka within three more days.It could take longer before enough food aid gets to the nearly 1 million people in need in hard-to-reach parts of Indonesia.Another serious problem is the need for purified water.
    Although aid had poured in from all over the world to the disaster areas,“Logistics is the big problem here—just getting the stuff out to people who need it,”said Ron Libby,emergency management specialist at the USA agency for International Development.
    Relief efforts are hindered by the difficulty of delivering aid to the more than 1000 islands scattered across hundreds of kilometers of ocean.
    For those who survived the tsunami's force,disease is now the No.1 problem.Five million people are short of water,food and basic sanitation across the region.World Health Organization(WHO) crisis chief David Navarro said 50 000 more people could die from disease and other causes,as has been the case in previous humanitarian emergencies.
    WHO said it had already received a handful of reports of malaria(疟疾) and dengue fever(登革热) and hundreds of reports of diarrhea(腹泻) and infected wounds.It said millions of water purification tablets had been sent to Asia,along with sanitation engineers to rebuild water sanitation infrastructure.
    Psychologists are warning that mental health problems caused by the tsunami could prove harder to resolve than the physical damage.
    Some survivors say they are plagued by recurring nightmares about walls of water.Many locals are afraid to return to beachside homes.Officials also warn that suicide rates could rise dramatically as parents struggle with guilt at losing children.
    Psychologists estimate that 20 to 30 per cent of people who face traumatic events eventually develop symptoms,such as alcohol abuse,lack of concentration at work and an inability to develop close relationships.
    Although the Thai Government has offered to build temporary beachside housing,many refugee families are refusing to come down from the hills.Others are afraid to go back to jobs on the sea.
    Over 150 000 people were killed by the tsunami,but hundreds and thousands more have been left with no means to earn a living.
    In the village of Akirapettai in India,all that is left is the twisted wreckage of the fishing fleet.Dakshina Murti,a fisherman,not only lost three family members,but also lost his boats,his nets,everything.
    “Everything's gone,”he says.With no government aid so far,all he has is a wreck.There are several million people who suffered the same experience.Homes have been destroyed,as well as wharves,docks,and sheds.
    For now,rebuilding the economy remains a distant concept.
    小题1:This passage is mainly about _________that happened around the Indian Oceans.
    A．the causes of the tsunamiB．the result after the tsunami
    C．the sign of the tsunamiD．the warning of the tsunami
    小题2:According to what the United Nations has said,the number of survivors in need of food aid after the disaster _________.
    A．is not more than 5 millionB．is less than 5 million
    C．has reached 5 millionD．won't reach 5 million
    小题3:From the passage we learn that _________ is the most serious problem for the time being.
    A．diseaseB．foodC．waterD．house
    小题4:The passage tells us that such a disaster,as tsunami will cause diseases and _________ as well.
    A．Dengue feverB．diarrheaC．MalariaD．mental health problem

    The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana（大麻）. That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to ten points off the user’s IQ.
    This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labeled（把……称为）the fleeting phenomenon of enhanced stupidity as “infomania”.
    The noticeable drop in IQ is believed to be the result of the constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the tasks in hand.
    The brain also finds it hard to deal with keeping lots of tasks in motion at once, reducing its overall effectiveness. While modern technology can have huge benefits, excessive(过度的)use can be damaging not only to a person’s mind, but to his or her social life.
    Eighty volunteers took part in clinical trials on IQ damage and 1,100 adults were interviewed.
    More than six in ten people polled admitted that they were addicted to checking their e-mail and text messages so that they examined work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and one in five would interrupt a meeting to do so.
    Furthermore, infomania is having a negative effect on work colleagues, increasing stress and disagreeing feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons believed that it was not only acceptable, but actually diligent and efficient to do so.
    67. What does the underlined part mean?
    A.A person’s IQ drops ten points if he or she always checks electronic messages.
    B. The person who has a higher IQ enjoys checking electronic messages.
    C. The person who has a lower IQ enjoys checking electronic messages.
    D. A person’s IQ is ten points higher if he or she always checks electronic messages.
    68. What happens to people with infomania?
    A. People with infomania can only concentrate on their tasks in hand.
    B. people with infomania are addicted to smoking marijuana.
    C. People with infomania can’t respond to technology immediately.
    D. People with infomania can’t concentrate on their tasks in hand.
    69. From the passage, we can learn that ______.
    A. about 550 interviewees responded to an e-mail immediately
    B. about 670 interviewees responded to an e-mail immediately
    C. about 50 taking part in clinical trials on IQ were addicted to checking e-mails
    D. about 16 taking part in clinical trials on IQ refused to answer e-mails immediately
    70. What is the main idea of this passage?
    A. The regular use of text messages and e-mails can be compared to smoking marijuana.
    B. Modern technology can damage a person’s mind.
    C. The regular use of text messages and e-mails can harm your IQ.
    D. Electronic messages have side effects on the user’s life.

    Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated（证明）that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles．When a fragrant（香的）flavor（作料）was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．
    In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria（自助） feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．
    So, in selecting food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”,  which humans soon lose．Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-established habits．Some people eat fox, dog and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．
    小题1:In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _____________ .
    A．encourage rats to drink vitamins-enriched water
    B．find out rats’ preference in flavor

    The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.
    The most widespread fallacy(谬误) of all is that colds caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
    During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.
    In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
    If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter？Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
    No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms(症状).
    51. The writer offered _______ examples to support his argument.
    A. 4            B. 5              C. 6              D. 3
    52. Which of the following does not agree with the chosen passage?
    A. The Eskimos do not suffer from colds all the time.
    B. Colds are not caused by cold.
    C. People suffer from colds just because they like to stay indoors.
    D. A person may catch a cold by touching someone who already has one.
    53. Arctic explorers may catch colds when _______.
    A. they are working in the isolated arctic regions
    B. they are writing reports in terribly cold weather
    C. they are free from work in the isolated arctic regions
    D. they are coming into touch again with the outside world
    54. Volunteers taking part in the experiments in the Common Cold Research Unit _______.
    A. suffered a lot                             B. never caught colds
    C. often caught colds                 D. became very strong
    55. The passage mainly discusses _______.
    A. the experiments on the common cold
    B. the fallacy about the common cold
    C. the reason and the way people catch colds
    D. the continued spread of common colds

    D        
    "In only six days I lost seven pounds of weight. "
    "Two full inches in the first three days!"
    These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to add to beauty or desirability.
    Often such products are nothing more than money-making things for their promoters. The results they produce are questionable and some are dangerous to health.
    To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration )can require proof (证明) under the Food, Drug, and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health. FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
    One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
    Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼),and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
    71. It can be inferred that the ads mentioned in the text are        .
    A. objective    B. costly    C. unreliable    D. illegal
    72. Which of the following is true according to the text?
    A. The court is in charge of removing dangerous products.
    B. New products are more likely to be questionable.
    C. The production of a device must be approved by FDA.
    D. The promoters usually just care about profits.
    73. FDA can ask for the proof of safety and effectiveness of a product        .
    A. if it is a drug      
    B. if it is a device
