Health Care and Epidemics (流行病)
Everyone suffers from disease at some time or another. However, millions of people around the world do not have good health care. Sometimes they have no money to pay for medical treatment. Sometimes they have money, but there is no doctor. Sometimes the doctor does not know how to treat the disease, and sometimes there is no treatment. Some people are afraid of doctors. When these conditions are present in large population centers, epidemics can start.
Epidemics can change history. Explorations and wars cause different groups of people to come into contact with other. They carry strange disease to each other. For example, when the Europeans first came to North and South America, they brought diseases with them that killed about 95 percent of the Native American population.
People are very afraid of unknown things, especially diseases. People have all kinds of ideas about how to prevent and treat disease. Some people think that if you eat lots of onions or garlic, you won' t get sick. Others say you should take huge amounts of vitamins. Scientific experiments have not proved most of these theories. However, people still spend millions of dollars on vitamins and other probably useless treatments or preventatives. Some people want antibiotics whenever they get sick. Some antibiotics are very expensive. Much of this money is wasted because some diseases are caused by a virus. Viruses are even smaller than bacteria, and they cause different kinds of diseases. Antibiotics are useless against viruses.
Because of their fear, people can be cruel to victims of disease. Sometimes they fire them from their jobs, throw them out of their apartments, and refuse them transportation services.
In the plague (瘟疫) epidemics a few hundred years ago, people simply covered the doors and windows of the victim' s houses and left them to die inside, all in an effort to protect themselves from getting sick.
Doctors know how most epidemic diseases spread. Some, like tuberculosis, are spread when people' s sneeze (喷嚏) sends the bacteria shooting out into the air. Then they enter the mouth or nose of anyone nearby.
Others are spread through human contact, such as on the hands. When you are sick and blow your nose, you get viruses or bacteria on your hands. Then you touch another person' s hand, and when that person touches his or her mouth, nose, or eyes, the disease enters the body. Some diseases spread when people touch the same dishes, towels, and furniture. You can pick up a disease when you touch things in public buildings.
Other diseases are spread through insects such as flies, mosquitoes, and ticks.
One disease that causes frequent, worldwide epidemics is influenza, or flu for short. The symptoms (症状) of influenza include headache and sometimes a runny nose. Some victims get sick to their stomachs. These symptoms are similar to symptoms of other, milder diseases. Influenza can be a much more serious disease, especially for pregnant women, people over sixty-five, and people already suffering from another disease, such as heart problems. About half of all flu patients have a high body temperature, called a fever. Flu is very contagious. One person catches the flu from another person; it doesn't begin inside the body as heart disease does.
Sometimes medicine can relieve the symptoms. That is, it can make a person cough less, make headaches less intense, and stop noses from running for a while. However, medicine can ' t always cure the disease. So far, there is no cure for many diseases and no medicine to prevent them. People have to try to prevent them in other ways.
Some diseases can be prevented by vaccination (接种疫苗). A liquid vaccine is injected into the arm or taken by mouth and the person is safe from catching that

C．NG
About 35% of all high school graduates in America continue their education in an institution of higher learning. The
word college is used to refer to either a college or a university. These institutions offer four-year programs that lead to a Bachelor of Arts (B.A.) or Bachelor Science (B.S.) degree. Some students attend a
junior college (providing only a two-year program) for one to two years before entering a four-year college as a
sophomore (二年级生) or junior (三年级生).
It is generally easier to be accepted at a state university than at a private one. Most private schools require strict
entrance examinations and a high grade point average (GPA), as well as specific college prep classes in high school.
Private schools cost considerably more than state colleges and famous private schools are very expensive. Poorer
students can sometimes attend, however, by earning scholarships. Some college graduates go on to earn advanced
masters or doctoral degrees in grad (graduate) school. Occupations in certain fields such as law or medicine require
such advanced studies.
Since college costs are very high, most students work at part-time jobs. Some have full-time jobs and go to school
part-time. Often some will take five or more years to complete a four-year program because of money / job demands
on their time.
While the college and work demands take up the great part of a student’s time, most still enjoy social activities. Sports,
dances, clubs, movies, and plays are all very popular. However, gathering together for long, philosophical talks at a
favorite meeting place on or near the university is probably the most popular activity.
College education is _______ in America.
A. quite common
B. very rare
C. something difficult
D. almost impossible

U. S. Life Expectancy Hits New High
Life expectancy rates in the United States are at an all-time high, with people born in 2005 projected to live for nearly 78 years, a new federal study finds.
The finding reflects a continuing trend of increasing life expectancy that began in 1955, when the average American lived to be 69.6 years old. By 1995, life expectancy was 75.8 years, and by2005, it had risen to 77.9 years, according to the report released Wednesday.
"This is good news." said report co-author Donna Hoyert, a health scientist at the National Center for Health Statistics. "It&39;s even better news that it is a continuation of trends, so it is a long period of continuing improvement."
Despite the upward trend, the United States still has a lower life expectancy than some 40 other countries, according to the U. S. Census (人口普查)Bureau. The country with the longest life expectancy is Andorra at 83.5 years, followed by Japan, Macau, San Marino and Singapore.
Much of the increase owes to declining death rates from the three leading causes of death in the country-heart disease, cancer and stroke.
In addition, in 2005, the U. S. death rate dropped to an all-time low of less than- 800 deaths per100,000.
Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine, said, "News that life expectancy is increasing is, of course, good. But the evidence we have suggests that there is more chronic disease than ever in the U. S."
Adding years to life is a good thing, Katz said. "But adding vital life to years is at least equally important. If we care about living well, and not just longer, we still have our work cutout for us." he said.
Since 1955， life expectancy rates in the U. S. have ___________. 查看材料
A.moved up and down
B.been declining
C.remained steady
D.been on the rise
Passage Two
Questions 62 to 66 are based on the following passage.
Yoga induces a feeling of well-being in healthy people, and can reverse the clinical and biochemical changes associated with metabolic syndrome, according to results of studies from Sweden and India. Metabolic syndrome is a cluster of heart disease risk factors such as high blood pressure, obesity and high blood sugar.
Dr. R.P. Agrawal, of the SP Medical College, Bikaner, India, and colleagues evaluated the beneficial effects of yoga and meditation in 101 adults with features of metabolic syndrome. In the study, 55 adults received three months of regular yoga including standard postures and Raja Yoga,while the remaining received standard care.
Waist circumference, blood pressure, blood sugar, and triglyceri HDL cholesterol levels were higher in the yoga group as compared joumal Diabetes REsearch and Clinicat Practice.
In the second study, published online December 19 in BioMed Central Complementary and Alternative Medicine, Dr. Anette Kjellgren from the University of Karlstad, Sweden and colleagues evaluated the beneficial effects of yoga-like breathing exercises on healthy volunteers.
55 adults were advised to practice "Sudarshan Kriya," which involves cycles of slow, normal and rapid breathing exercises. The exercises were practiced for an hour daily, six days a week for six weeks, while 48 controls were advised to relax in an armchair for I 5 minutes daily.
At the end of the study period, feelings of anxiety, stress and depression were significantly lower and levels of optimism significantly higher in the yoga group compared to the control group, Kjellgren and colleagues report.
Yoga induces a "relaxation response" associated with reduced nervous system activity and a feeling of well-being probably due to an increase in antioxidants(抗氧化剂) and lower levels of the stress hormone cortisol(应激激素皮质醇 ), they suggest.
Yoga not only helps in prevention of lifestyle. diseases, but can also be "a powerful adjunct therapy when these diseases anse,” co-investigator Dr. Faahri Saatiglou, from the University of Oslo, told Reuters Health. "We do not emphasize this point enough in our Westem health care."
The studies of yoga from Sweden and India have shown that __
A. yoga will make patients recover more quickly
B. yoga can cure cancer gradually
C. yoga will lead the state of being healthy
D. yoga can keep people optimistic
While it's true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells haven't begun to specialize.
Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells-brain cells in Alzheimer's, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few. If doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue.
It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem ceils and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations; but if efforts to understand and master stem-cell development prove successful, doctors will have a therapeutic tool of incredible power.
The same applies to cloning, which is really just the other side of the coin; true cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, genetically identical to its parent.
For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year.
Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells., the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure."
The writer holds that the potential to make healthy body tissues will ______.
A．aggravate moral issues of human cloning
B．bring great benefits to human beings
C．help scientists decode body instructions
D．involve employing surgical instruments
Questions are based on the following passage．
Saying they can no longer ignore the rising prices of health care， some of the most influentialmedical groups in the nation are recommending that doctors weigh the costs， not just the effectiveness of treatments， as they make decisions about patient care．The shift， little noticed outside the medical establishment but already controversial inside it，suggests that doctors are starting to redefine their roles， from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent．In practical terms， the new guidelines being developed could result in doctors choosing one drug over another for cost reasons or even deciding that a particular treatment—at the end of life， for example—is too expensive．In the extreme， some critics have said that making treatment decisionsbased on cost is a form. of rationing．Traditionally， guidelines have heavily influenced the practice of medicine， and the latest ones areexpected to make doctors more conscious of the economic consequences of their decisions， even though there"s no obligation to follow them．Medical society guidelines are also used by insurancecomoanies to help determine reimbursement （报销） policies．Some doctors see a potential conflict in trying to be both providers of patient care and fmancial
Overseers．"There should be forces in society who should be concerned about the budget， but they shouldn"t be functioning simultaneously as doctors，" said Dr．Martin Samuels at a Boston hospital．He said doctors risked losing the trust of patients if they told patients， "I"m not going to do what I think is best for you because I think it"s bad for the healthcare budget in Massachusetts．" Doctors can face some grim trade—offs．Studies have shown， for example， that two drugs are about
equally effective in treating macular degeneration， and eye disease．But one costs $ 50 a dose and the other close to $ 2，000．Medicare could save hundreds of millions of dollars a year if everyone used the cheaper drug， Avastin， instead of the costlier one， Lucentis．But the Food and Drug Administration has not approved Avastin for use in the eye．and using it rather than the alternative， Lucentis， might carry an additional， although slight， safety risk．Should doctors consider Medicare"s budget in deciding what to use？"I think ethically （在道德层面上） we are just worried about the patient in front of us and not trying to save money for the insurance industry or society as a whole，" said Dr．Donald Jensen．Still， some analysts say that there"s a role for doctors to play in cost analysis because not many others are doing so．"In some ways，" said Dr．Daniel Sulmasy， "it represents a failure of wider society
to take up the issue．"
What do some most influential medical groups recommend doctors do？ 查看材料
A.Reflect on the responsibilities they are supposed to take．
B.Pay more attention to the effectiveness of their treatments．
C.Take costs into account when making treatment decisions．
D.Readjust their practice in view of the cuts in health care．
