    Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he has sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.
    Then, consider this: you might be in a state of sub-health（亚健康）. Sub-health, also called the third state or gray state, is explained as a borderline（界限）state between health and disease.
    According to the survey by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week.
    Symptoms include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.
    The key to preventing and recovering from sub-health, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities.
    As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements -- vitamins and other elements that are important to the body.
    Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract（消化道）. They also say that a balanced diet is very helpful in avoiding sub-health.
    小题1:.
    According to this passage, which of the following is true?
    A．When you are in a state of sub-health, you should stay at home and keep silent.
    B．When you are in a state of sub-health, you should go to see a doctor and buy some medicine.
    C．When you are in a state of sub-health, you should have yourself examined in foreign countries.
    D．When you are in a state of sub-health, you should find out the reasons and relax yourself.

    It is obvious that doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?
    The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.
    “So while doctors may tell patients they are overweight, the conversation often ends there,” said Christine C. Ferguson, director of the Stop Obesity Alliance. “Patients are not told about the possibility of diabetes (糖尿病),” she said. “And doctors don’t feel they have good information to give. They felt that they didn’t have adequate tools to address this problem.
    The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know that they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.
    Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past—and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity­related diseases like hypertension and diabetes.
    Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re to be successful with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them,” he said.
    He acknowledged that many doctors tend to be not optimistic.
    “Part of this is that there’s this common belief, and doctors are burdened by it, too, that overweight people are weak-willed and just don’t have any willpower and are self­indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”
    小题1:What is the Stop Obesity Alliance most probably in Paragraph 3?
    A．An organization of doctors suffering from obesity.
    B．An organization of patients suffering from obesity.
    C．A research group that conducts special surveys about overweight people.
    D．A research group dealing with doctor-patient relationship.
    小题2:How many of the patients surveyed have been advised by their doctors to lose weight?
    A．About 350.B．About 390.
    C．About 900.D．About 1,000.
    小题3:What can be inferred about obesity patients in Paragraph 5?
    A．They are not as hopeless as doctors think they are.
    B．Most of them have tried hard to lose weight, but in vain.
    C．Without their doctors’ constant coaching, there is little chance of their succeeding in losing weight.
    D．Most of them have just given up their hope of becoming less heavy.
    小题4:According to the passage, which factor contributes to the lack of dialogue between doctors and patients?
    A．Most doctors never think of warning their patients about their weight problem.
    B．Many doctors find it difficult to persuade overweight people to lose weight.
    C．Most patients are too weak-willed to do anything about their weight.
    D．Many patients tend not to trust their doctors about their weight problem.
    小题5:Which of the following is the best title of the passage?
    A．Obesity in the U. S.
    B．Trouble of overweight Americans.
    C．Talk more, help better.
    D．Doctors or patients---who to bear more blame?[

    Bruce Alberts, the former President of the National Academies (USA), has now taken over as Editor-in Chief of Science. Judging by his editorial in this week’s issue Considering Science Education there could be some interesting times ahead in Science offices.
    Here’s part of what Bruce has to say about science education…
    I consider science education to be critically important to both science and the world, and I shall frequently deal with this topic on this page. Let’s start with a big-picture view. Science has greatly advanced our understanding of the natural world and has enabled the creation of countless medicines and useful devices. It has also led to behaviors that have improved lives. The public appreciates these practical benefits of science, and science and scientists are generally respected, even by those who are not familiar with how science works or what exactly it has discovered.
    But society may less appreciate the advantage of having everyone acquire the ways of thinking and behaving that are central to practice of successful science: scientific habits of mind. These habits include a critical attitude toward established claims and a strong desire for logic and evidence. As famous astronomer Carl Sagan put it, science is our best detector (检测器). Individuals and societies clearly need a means to logically test the constant clever attempts to operate our purchasing and political decisions. They also need to challenge what is unreasonable, including the intolerance that led to so many regional and global conflicts.
    So how does this relate of science education? Might it be possible to encourage, across the world, scientific habits of mind, so as to create more rational (理性的) societies everywhere? In principle, a strong expansion of science education could provide the world with such an opportunity, but only if scientists, educators, and policy-makers redefine (重新定义) the goals of science education, beginning with college-level teaching. Rather than only conveying what science has discovered about the natural world, as is done now in most countries, we should provide first all students with the knowledge and practice of how to think like a scientist.
    小题1: Which of the following is NOT included in the “scientific habits of mind”?
    A．A critical attitude toward established claims.B．A strong desire for logic.
    C．A clever and active mind.D．A strong desire for evidence.
    小题2: What does the underlined phrase “such an opportunity” refer to in the last paragraph?
    A．To create more rational societies everywhere.
    B．To relate decision-making to science education.
    C．To encourage science education around the world.
    D．To set right goals of science education.
    小题3:In Bruce Alberts’ opinion, which is the most important in science education?
    A．Offering all students enough practice to drill their mind.
    B．Equipping all students with a thinking model of a scientist.
    C．Telling students what science has discovered about the natural world.
    D．Advising all students to challenge all established scientific achievements.
    小题4:Which of the following would be the best title for this passage?
    A．Bruce Alberts, a great science educator
    B．Science education and world peace
    C．The government and science education
    D．Bruce Alberts’ opinion on science education

    You'd be forgiven for thinking that running after children each day would leave parents in the best shape of their lives.But a study has found that the mothers and fathers of young children are more unhealthy than their childless peers(同龄人）.
    Mothers with young children are heavier and eat more calories and fatty foods,and consume more sugary dinks than chidless women,scientists said.And both sexes are less active than those in their age group without children.
    Parents often choose quick,easily preparesd foods that are high in fat and calories,and by choosing these foods they may in turn serve them to their children,forming a cycle of unhealthy diet.
    Dr.Berge,one of the study authors,said:“This isn't a study about blame,this is about spotting a very high-risk time period for parents that doctors should be aware of ,so they can offer solutions(解决办法）.”
    According to the study ,mothers ate more fatty foods and drank about seven sugary drinks weekly,equal to about four chidless women.They also had an average of 2,360 calories daily,368 calories more than women without children,With that many calorise,women that age would need to be active to avoid to avoid gaining weight.
    Fathers ate about the same amount of daily calories childless men and both had an average boby-mass index(指数）,but fathersgot less physical activity—about five hours weekly ,compared to almost seven hours among chidless men.
    The study has several limitations－there's no data on how many women reccently had babies.Ther's also no information on the number of single parents,who likely face diet and exercise challenges.Sarah Kriger,an American dietician who works with new mothers said some of the mothers may have had postpartum(产后）depression,which might affect their eating and exercise habits.
    小题1:What does the author mainly aim to tell us in the passage?
    A．Childless couples live a much happier life than those with children.
    B．Mothers will be unhealthy because of the postpartum deprdession
    C．Couples of young children eat more fatty foods and lead unhealthier lives.
    D．Fathers tend to eat high calorie foods because they should run after thrie children.
    小题2:The underlined part“in the best shape”in the first paragraph means that a person  .
    A．is busy and tiresB．has a most harmonious family
    C．enjoys the most happinessD．is in the most healthy condition
    小题3:Which of the following is NOT mentioned about mothers with children?
    A．They are less active
    B．They eat unhealthy foods
    C．They may feel unhappy aftre having babies
    D．They may lose their jobs aftre having babies
    小题4:What Dr.Berge says in Paragraph 4 suggests that    .
    A．Parents should pay more attention to their chidren
    B．doctors should do something with parents'high-risk time period
    C．the study has drawn attention of doctors and young parents
    D．parents should not be blamde for having an unhealthy lifestyle
    小题5:We can learn from the last paragraph that      .
    A．the result of the study result in aan unscientific way
    B．the study was carried out in an unscientific way
    C．single mothers are surely facing quyite different situation

    Bad moods can actually be good for you, with an Australian study finding that being sad makes people less gullible (轻信), improves their ability to judge others and also boosts memory.
    The study, authored by psychology professor Joseph Forgas at the University of New South Wales, showed that people in a negative mood were more critical of, and paid more attention to, their surroundings than happier people, who were more likely to believe anything they were told.
    "Although positive mood seems to promote creativity, flexibility, cooperation, and reliance on mental shortcuts, negative moods trigger (引发) more attentive, careful thinking, paying greater attention to the external world," Forgas wrote.
    "Our research suggests that sadness ... promotes information processing strategies best suited to dealing with more demanding situations."
    For the study, Forgas and his team conducted several experiments that started with inducing happy or sad moods in their subjects through watching films and recalling positive or negative events.
    In one of the experiments, happy and sad participants were asked to judge the truth of urban myths and rumors and found that people in a negative mood were less likely to believe these statements.
    People in a bad mood were also less likely to make snap decisions based on racial or religious prejudices, and they were less likely to make mistakes when asked to recall an event that they witnessed.
    The study also found that sad people were better at stating their case through written arguments, which Forgas said showed that a "mildly negative mood may actually promote a more concrete, accommodative and ultimately more successful communication style."
    "Positive mood is not universally desirable: people in negative mood are less prone to judgmental errors, are more resistant to eyewitness distortions（扭曲）and are better at producing high-quality, effective persuasive messages," Forgas wrote.
    The study was published in the November/December edition of the Australian Science journal.
    小题1:_ The study suggests that when someone is in a bad mood, he ________ .
    A．is particular about everythingB．shows less concern about others
    C．is willing to believe what he hearsD．cares more about his surroundings
    小题2:_Which of the following is connected with positive mood?
    A．New ideas.B．Being stubborn.C．Being careful.D．Concentration.
    小题3:_ How did researcher put the subjects in good or bad moods?
    A．By watching sports programs.B．By listening to happy or sad stories.
    C．By dealing with demanding situations.D．By thinking back on their past experience.
    小题4:_ Which of the following statements is TRUE according to the text?
    A．Positive mood leads to better judgement.
    B．Sad people remembered what they saw precisely.
    C．Cheerful people were less likely to believe rumors.
    D．People in bad mood tend to make quick decisions.
    小题5:_The author intends to convince(说服) us that __________ .
    A．Joseph Forgas made a great discoveryB．bad moods can actually be good for us
    C．we should think positively and negativelyD．the Australian study is of practical value

    Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．
    Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．
    By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group           C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．
    “The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．
    “Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．
    小题1:Why did the scientists carry on the new research?
    A．To find out if laughter was good to health．
    B．To discover the best medicine to cure diabetes．
    C．Because the number of diabetic patients is the largest in the world．
    D．Because diabetic patients need more laughter than other patients．
    小题2:After 12 months into the study, ___________．
    A．C-reactive proteins increase 66 percent in Group C
    B．the level of the hormones epinephrine stays the same in both groups
    C．the level of the hormones epinephrine has dropped
    D．C-reactive proteins reduced 66 percent in Group L
    小题3:The underlined part “HDL cholesterol” in Paragraph 3 must be _______．
    A．something bad to our healthB．something good to our health
    C．a kind of wonderful medicineD．a kind of dangerous disease
    小题4:In what way does laughter benefit people’s health?
    A．Blood is made thick by laughter．B．Laughter makes blood vessels thin．

    Traditional surgical procedures require surgeons to make large incisions(伤口) in a patient’s body in order to gain access to the internal organs. It was once common for heart surgeons, who perform highly specialized and complex procedures, to make long incisions in a patient’s chest and then split the breastbone to reach the heart. Patients who undergo surgery are often at the risk of infection, as bacteria can infect the cut in the skin. In addition, there is often a lengthy recovery period.
    A surgical technique known as “keyhole surgery” has become more common in recent years. In general, the surgeon will make a couple of small incisions around the area where the operation is going to be performed. Tubes are pushed into the holes, and a tiny camera, which is called an endoscope, is put into the body. The camera is attached to a large monitor screen that is positioned so that the doctor can see it while he performs the operation. In addition to the camera, doctors also push their tiny surgical instruments through the tubes. The awkward part of keyhole surgery is that it is counterintuitive; that is to say, if a surgeon wants to move the tool to the left, he or she must push it to the right.
    Other advancements in technology are also being used today in the OR (operation room). A new machine called the “da Vinci Surgical System” has been tested in hospitals in the U.S.. Unlike keyhole surgery, the da Vinci’s robot’s moving parts are designed to imitate the natural hand and wrist movement of a surgeon, thus providing better control and sensitivity. The system is controlled by a surgeon from a console(控制台). Sitting at a console a few feet from the patient, the surgeon can perform an operation by holding and moving highly sensitive pads that enable him or her to control the instruments. The area of the body on which the surgeon is working is enlarged on a screen, which is attached to the console. This gives surgeons a realistic three-dimensional view of the area — similar to what they would see during a traditional surgical procedure.
    Although the da Vinci Surgical System is undergoing some trials for some procedures, it has been welcomed as revolutionary by many surgeons. Patients with serious illnesses must still undergo major surgery, but the smaller incisions and less invasive procedures typically mean that a shorter recovery time is needed. In some cases, the patient’s stay in the hospital has been cut in half when the da Vinci Surgical System was used. On the downside, some operations have taken up to fifty minutes longer because surgeons are inexperienced at using the new technology. As surgeons become more familiar with the machines, the time needed for surgical procedures is likely to decrease.
    小题1:What can be learned about the traditional surgery according to the passage?
    A．The cost of the traditional surgery is very high.
    B．It often leaves a large wound in a person’s body.
    C．Long incisions are made in a patient’s chest.
    D．The incision is often infected after the operation.
    小题2: Which of the following is one DISADVANTAGE of keyhole surgery?
    A．It requires the use of long, thin tools and a tiny camera.
    B．The doctor can not view the inside of the patient’s body clearly.
    C．The direction in which a doctor moves the surgical tools is reversed.
    D．An endoscope has to be inserted into the patient’s body in advance.
    小题3: The da Vinci Surgical System differs from keyhole surgery in that _______.
    A．requires that a surgeon make more small incisions on a patient
    B．reduces the amount of time it takes to perform a surgical procedure
    C．allows the surgeon to use the surgical instruments more sensitively
    D．eliminates the need for surgeons to make large incisions on patients
    小题4: The passage mainly tells the reader ________.
    A．the challenges brought about by new technology
    B．the benefits and drawbacks of the da Vinci Surgical System
    C．the reflections on the development in medical science
    D．the application of new technologies in modern surgery
