     A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
    Forty-four percent of people are actually looking for doctors or other providers when they search for health information online. Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition.
    The Internet has also become an important source of emotional support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition. It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease. They are so eager to find other people online who share their health concerns.
    A disease is considered rare if it affects fewer than two hundred thousand people worldwide. The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other. Dr. Jeff Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients.
    “We provide the patient full access to their medical care. Anything I can see, the patient can see. All of their notes, all of their doctor visits are right there. All of their lab work is right there.” Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
    小题1:From the first paragraph, we can know _________.
    A．most online health information is reliable
    B．more people now turn to the Internet for medical advice
    C．people shouldn’t rely on the Internet for medical advice
    D．doctors are no longer the patients’ first choice
    小题2: The underlined words “off the charts” in Paragraph 3 mean _________.
    A．very popularB．not accessibleC．far away fromD．not attractive
    小题3: By using social networking, patients with rare diseases can _________.
    A．find effective curesB．get emotional comfort
    C．ask for financial supportD．consult doctors anytime
    小题4: Which of the following is NOT true of Dr. Livingston’s software?
    A．It cuts down medical expenses.
    B．It decreases the time spent on medical care.
    C．It takes doctors closer to their patients.
    D．It gives patients a medical test online.

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

    试题分析:
    小题1:这是细节理解题。根据第一自然段A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
    医生仍然健康咨询的首选，但是有很多人在网上搜寻信息，故正确答案为B。
    小题2:这是词义猜测题。根据It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease.在网上搜寻健康信息在4分之一慢性病人中受欢迎，后面有And可以判断前后两句是顺承关系，应该说的是同一话题，在网上搜寻健康信息在得怪病人的中间也受欢迎，故正确答案为A。温馨提醒：not accessible不可访问的；far away from远离；not attractive不吸引人的，该题既考查了这几个短语的意义同时又考查了学生的对上下文理解与推测的能力
    小题3:这是细节理解题。根据The Internet has also become an important source of emotional support for people with health problems.和 The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone.可知在网上搜寻健康信息给得怪病人的一精神安慰，故正确答案为B。
    小题4:这是细节理解题。根据Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
    可知在网上搜寻健康信息可以省时、减少费用、能够拉近与医生之间的距离。只有D项在本文中没有出现，故选D。
    点评：文章通过多次调查发现，现在人们喜欢在网上查找有关医学知识，在网上咨询自己的病情，以便对病情有更好的治疗。做阅读题一定要紧扣短文的意思，不要凭借自己的主观臆断做题。细节理解题都能在原文中找到答案。

    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.

    With big handbags becoming a key fashion accessory(配饰) for working women, health experts are warning they can also become a key health concern.
    Bags for women have become bigger and heavier as designers combine briefcases with handbags and straps have become longer, resulting in many users complaining of neck, shoulder and back problems.
    “I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up,”said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas.“We take it over to the scale and weigh it and usually they’re anywhere from 7 to 10 pounds. We’re really going to see women with more and more problems later on if we continue the big purse craze.”
    William Case, a physical therapist(临床医生)in private practice in Houston, Texas, urged designers“to place a cute, educational caution tag(标签) on all bags to inform buyers of potential neck and shoulder dangers.”Above all, he suggested correct posture while carrying big purses, keeping the head and shoulders upright. Patients should also often change the size and weight of purses carried.
    “The extra-large purses are quite extraordinary. They look beautiful when the women wear them, but I don’t know how aware they are of the potential problems,”Case said.
    Placing objects on one shoulder was one of the least efficient(高效率的) ways of carrying a load, according to a professor from Cornell University in New York State.“This causes a great imbalance,”he said.“If a big bag is a fashion accessory, then occasional and symbolic use is fine. If not, then keep it light.”
    小题1:Jane Salder would“look for their purse and pick it up”in order to see whether the purses                        .
    A．contained enoughB．were worth a lot of pounds
    C．were too heavyD．were too large
    小题2:Which correctly explains the meaning of the underlined word“posture”in the 4th paragraph?
    A．The way you position your body.
    B．The part of your body where you place a weight.
    C．The strength you use to carry a weight.
    D．The height of the weight you carry.
    小题3: None of the experts advised big bag users to             .
    A．be aware of the big-bag problems
    B．wear big bags in the right way
    C．avoid using big bags very often
    D．give up the fashion to keep fit

    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

    “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 good shapes and new look 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 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 Drug Administration) can require proof under the Food, Drug and Cosmetic Act that it 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 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 ads mentioned in the text are_____.
    A．objectiveB．costlyC．unbelievableD．illegal
    小题2: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3:The author intends to______.
    A．make consumers aware of the promoters’ false promise
    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
    小题4: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.
