    第三部分：阅读理解（共20小题；每小题2分，满分40分）
    阅读下列短文，从每题题所给的四个选项（A、B、C、D和E）中选出最佳选项。
    Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.
    New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.
    But the good news is that doing chores in the house or gently walking around the office while on the phone might be enough to keep you fit.
    The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.
    The study measured the intensity of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids(脂肪).
    “Higher levels of blood lipids have been linked to a heightened risk of heart disease,” principal researcher Genevieve Healy of the University of Queensland said. “What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time.”
    Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into the impact of long sitting time on health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job.
    The latest study builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day.
    The Australian research has been hacked up by US studies.
    “To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles,” said Professor Marc Hamilton from the University of Missouri. “There is a large amount of energy associated with standing every day that cannot easily be replaced by 30 to 60 minutes in the gym.”
    56. What’s the aim of the Stand Up Australia project?
    A. To study the factors influencing productivity of workers.
    B. To study the reasons for the longer sitting time at work.
    C. To develop and test strategies for reducing sitting time in the office.
    D. To develop and test strategies for reducing working time.
    57. The purpose of the last paragraph is to       .
    A. provide a scientific basis for the benefits of standing up
    B. Compare the effect of standing with exercising in the gym
    C. report the new research findings of professor Marc Hamilton
    D. figure out the amount of energy associated with daily standing
    58. What’s the best title for the text?
    A. Exercise in the Gym Is Out.
    B. Your Office Chair Is Killing You.
    C. A Cause of Heart Disease.
    D. Good News for Workers.

    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．
    C．Laughter increases blood pressure．D．Laughter makes blood flow fast．
    小题5:According to Berk, we should _________．
    A．choose lifestyles carefullyB．change our lifestyles
    C．prevent our lifestyles in advance D．pay less attention to the positive emotion

    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

    Who says Americans worship the almighty dollar? It’s not true．Having enough free time is more important to most Americans than being rich, according to a new poll．
    Only 13 percent of more than 2,400 people questioned in the telephone poll ranked being wealthy as most important to them, while 67 percent ranked free time as their top priority, higher than having a successful career, getting married, and having children．"Everyone wants free time to do the things they want to do, young, middle-aged or old," said Richard Morin, of the Pew Social & Demographic Trends Project, which conducted the survey．"So our desire to play unites us．"
    The poll also showed that people who were university educated valued career success over wealth, as middle-aged people did．Not surprisingly, those who didn't have money, ranked wealth very highly．This included minorities, first generation Americans and less educated people．The survey also revealed that a disproportionate （不成比例的） number of people under the age of 30 and retirees in the group made $ 20,000 or less a year．But the emphasis on wealth lessens with age, with younger people putting value on it but hardly any seniors．"It just diminishes with time as the reality sets in that you would never be rich," Morin said．"But also, the reality sets in that you don't have to be rich to lead a very comfortable and fulfilling life．"
    While wealth was not at the top of people' s list of priorities, 43 percent still said it was somewhat important．
    56．The poll showed that the majority of American people ranked ____ as the most important．
    A．wealth              B．a successful career 
    C．marriage            D．free time
    57．Who cares least for wealth, according to the passage?
    A．Young people．                    B．Middle-aged people．
    C．Old people．                       D．Well-educated people．
    58．The underlined word "diminishes" in the third paragraph probably means "____"．
    A．to increase          B．to decrease          C．to change          D．to stay

    Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.
    The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases.
    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.
    Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
    People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.
    67. What is the main cause that people suffer from a lot of new sicknesses?
    A. Ancient people did a great deal of physical exercise.
    B. People today have a lot of alcohol.
    C. People today have more tobacco.
    D. Food today is quite different from that of ancient times.
    68. Which of the following belongs to the dairy products?
    A. Milk             B. Corn     C. Pork            D. Flour
    69. New kinds of sicknesses have been found because ________.
    A. the human body has changed compared with humans who first appeared on the earth
    B. the way we live has changed a little
    C. our body can’t deal with the changes in life style
    D. the way we live today is proper for the human body
    70. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________.
    A. milk and other dairy products                        B. salt and sugar
    C. wild animals, fresh wild vegetables and fruits     D. grain foods
