    Eating a diet high in processed（加工） food increases the risk of depression（抑郁）, research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
    Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food，which includes lots of fruit, vegetables and fish，and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat，refined（精制的） grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
    Those who ate the most wholefood（全天然食物） had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods.
    Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.（解释原因） He also pointed in a paper that a Mediterranean(地中海) diet was associated（有关） with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood （可能）of you eating a Mediterranean diet is not very high.
    Dr．Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
    He added people's diets were becoming increasingly unhealthy. The UK population is consuming （消费）less nutritious, fresh produce and more saturated（饱和） fats and sugars.
    小题1:The text is mainly about______.
    A．the increasingly unhealthy diet of the UK population
    B．the link between processed food and depression
    C．the relationship between physical and mental health
    D．the emotional state of the British People
    小题2:What can we learn from what Dr. Archana Singh Manoux said?
    A．It is difficult for most British people to have a Mediterranean diet.
    B．The Mediterranean diet is the most healthy in the world.
    C．Many studies have been done on the Mediterranean diet before.
    D．The Mediterranean diet is not good for depression.
    小题3:Dr. Andrew McCulloch agrees that______.
    A．our diets are closely related to our mental health
    B．the present study needs more facts and other information
    C．the UK population will become ill in the near future
    D．more saturated fats and sugars should be taken in
    小题4:Why might the author have written this text?
    A．To tell people what a healthy diet actually is.
    B．To prove people’s diets are increasingly unhealthy.
    C．To encourage people to cut down on processed food.
    D．To introduce some experts on the research team.

    小题1:B
    小题2:A
    小题3:A
    小题4:C
    文章主要介绍了食物是否加工对人类的影响，多吃加工食物会增加人的抑郁情绪。并指出人们的饮食越来越不健康。
    小题1:B 文章主旨题。文章主要讲述了加工食物对人类抑郁的影响。故选B

    Researchers have found more evidence that suggests a relationship between races (种族) and rates (率) of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.
    Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2.000 people in the study developed lung cancer.
    Researchers say genetics (遗传学) might help explain the racial and ethnic（种族的） differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference.
    African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer.
    Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted (针对) medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine."
    小题1:Researchers agree that it is     that may probably determine black people’s risk of lung cancer.
    A．the larger amount of smoking than white people
    B．the living style or habit of the blacks
    C．the depth of cigarette smoke into their lungs
    D．the physical strength to react to cigarette smoke
    小题2:People in the new study are made up of         .
    A．heavy smokers in AmericaB．smokers and non-smokers
    C．the Asians and HawaiiansD．the black and white people
    小题3:The production of BiDil referred to in the last paragraph is to     .
    A．explain different races react to some diseases differently
    B．tell the readers that racial differences exist in smokers
    C．show a big step people have taken in the medicine area
    D．support the idea that it is easy for blacks to have cancers
    小题4:Which of the following statements is TRUE according to the author?
    A．The way of smoking may increase the risk of lung cancer.
    B．Race has nothing to do with the risk of having a lung cancer.
    C．The research was started by the New England Journal of Medicine.
    D．he risk of lung cancer lies I how much a person smokes.

    Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.
    According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
    Think back to the time you took your very first sip of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation(attraction) you need will power to resist, they never, ever start out that way.
    Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
    These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.
    小题1:What do most people think causes bad behavior?
    A．Being forced by others. B．Not having enough will power.
    C．Enjoying their first experiences.D．Following the examples of their friends.
    小题2:The author mentions his experience in the third paragraph to prove ____.
    A．will power helps develop bad habits sometimes
    B．drinking beer is harmful to the health of teenagers
    C．self-control should be developed when one is young
    D．everyone can be challenged by different temptations
    小题3:In the last paragraph, the author stresses(强调) that ____.
    A．without self-control, no one can succeed
    B．bad habits don’t always lead to bad results
    C．applying self-control correctly is important
    D．people can develop wisdom from bad behavior
    小题4:What would be the best title for the passage?
    A．My First Sip of BeerB．Do You Have Will Power ?
    C．Will Power Benefits UsD．Dark Side of Self-control

    Is losing weight as simple as doing a 15-minute writing exercise? In a new study, women who wrote about their most important values, like close relationships or religion, lost more weight over the next few months than women who didn't. "We have this need to feel self-integrity (正直,诚实）,” says Christine Logel of the University of Waterloo. "When something threatens your sense that you're a good person, like failing a test, we can buffer（缓冲） that self-integrity by reminding ourselves how much we love our children, for example".
    For this study, the researchers recruited 45 female undergraduates, of whom 58% were overweight. Each woman was weighed, and was then given a list ofimportant values, like creativity, music or relationships with friends and family members. Each woman ranked the values in order of how important they were to her. Then half the women were told to write for 15 minutes about the value that was most important to her. The other half, a control group, were told to write about why a value far down on their list might be important to someone else.
    The women came back months later to be weighed again. Women who had written about an important value lost an average of 3.41 pounds, while women in the control group gained an average of 2.76 pounds.
    "How we feel about ourselves can have a big effect," Logel says. Maybe when one of the women who wrote about an important value went home that night, she felt good about herself and didn't eat to make herself feel better. Over a few months, that could make a real difference in her life,
    小题1:How can a 15-minute writing exercise ofimportant values affect people?
    A．They will feel proud of themselves and gain weight gradually.
    B．They may feel good about themselves and then eat less than usual.
    C．They may continue writing and decide to become a professional writer.
    D．They will never have meals at night to make themselves lose weight.
    小题2:What were the females required to do in the study?
    A．Only the control group was given a list ofimportant values.
    B．Both groups ranked the values in order of importance to them.
    C．Each woman was weighed three times in the process of the study.
    D．The overweight women wrote about the value most important to them.
    小题3:Which of the following persons may lose weight according to the new study?
    A．Mary who wrote about her own adventure.
    B．Catherine who described her illness in her writing.
    C．Shirley who wrote how much she loved her children.
    D．Alice who complained her boss in her diary.
    小题4:Which of the following might be the best title for the passage?
    A．Writing Benefits Women a Lot
    B．Losing Weight Is Very Simple
    C．Writing Contributes to Losing Weight
    D．Women Values Losing Weight

    “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 money­making 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 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.
    小题1:It can be inferred that the ads mentioned in the text are________.
    A．objectiveB．costlyC．unreliableD．illegal
    小题2: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
    C．if its consumers make complaints
    D．if its distributors challenge FDA's authority
    小题3:The Relaxacisor is mentioned as________.
    A．a product which was designed to produce electricity
    B．a product whose distributor was involved in a legal case
    C．a successful advertisement of a beauty product
    D．an example of a quality beauty product
    小题4:The author intends to________.
    A．make consumers aware of the promoters' false promises
    B．show the weakness of the law on product safety
    C．give advice on how to keep young and beautiful
    D．introduce the organization of FDA

    I know what you're thinking: pizza? For breakfast? But the truth is that you can have last night's leftovers in the a. m. if you want to.
    I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don't have time, others think they're “saving” calories, still others just don't like breakfast food.
    But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R, D, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it's loaded with vegetables, and you stick to one small piece.
    Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
    So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers－it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it... you may save yourself some pre­bedtime calories. And watch your body gain the fat­burning effects.
    小题1:The underlined word "leftovers" in Paragraph 1 probably means ______.
    A．food remaining after a meal B．things left undone
    C．meals made of vegetables D．pizza topped with fruit
    小题2:What can we infer from the text?
    A．Working women usually have breakfast in a hurry.
    B．Many people have wrong ideas about breakfast.
    C．There are some easy ways of cooking a meal.
    D．Eating vegetables helps save energy.
    小题3:According to the last paragraph, it is important to ______.
    A．eat something for breakfastB．be careful about what you eat
    C．heat up food before eating itD．eat calorie- controlled food
    小题4:The text is written mainly for those _______.
    A．who go to work earlyB．who eat before sleep
    C．who stay up lateD．who want to lose weight

    It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage．Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
    Dr．Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain．
    Dr．White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys’ brains. When the brain’s temperature was 10 ℃, Dr．White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them．
    小题1:The biggest difficulty in operating on the damaged brain is that____ ．
    A．the time is too short for doctors
    B．the patients are often too nervous
    C．the damage is extremely hard to fix
    D．the blood-cooling machine might break down
    小题2:The brain operation was made possible mainly by____ ．
    A．taking the blood out of the brain
    B．trying the operation on monkeys first
    C．having the blood go through a machine
    D．lowering the brain’s temperature
    小题3:With Dr. White’s new idea, the operation on the damaged brain____ ．
    A．can last as long as 30 minutes
    B．can keep the brain’s blood warm
    C．can keep the patient’s brain healthy
    D．can help monkeys do different jobs
    小题4:What is the right order of the steps in the operation?
    a．send the cooled blood back to the brain 　　b．stop the blood to the brain
    c．have the blood cooled down 　　         d．operate on the brain
    A．a,b,c,dB．c,a,b,dC．c,b,d,aD．b,c,d,a
