第2题
Most people would be impressed by the high quality of medicine available to most Americans
. There is a lot of specialization, a great deal of attention to the individual, a vast amount of advanced technical equipment, and intense effort not to make mistakes because of the financial risk which doctors and hospitals must face in the courts if they handle things badly.

But the Americans are in a mess. The problem is the way in which health care is organized and financed. Contrary to public belief, it is not just a free competition system. To the private system has been joined a large public system, because private care was simply not looking after the less fortunate and the elderly.

But even with this huge public part of the system, which this year will eat up 84.5 billion dollars—more than 10 percent of the U.S. budget—large numbers of Americans are left out. These include about half the 11 million unemployed and those who fail to meet the strict limits on income fixed by a government trying to make savings where it can.

The basic problem, however, is that there is no central control over the health system. There is no limit to what doctors and hospitals charge for their services, other than what the public is able to pay. The number of doctors has shot up and prices have climbed. When faced with toothache, a sick child, or a heart attack, all the unfortunate person concerned can do is pay up.

Two-thirds of the population are covered by medical insurance. Doctors charge as much as they want knowing that the insurance company will pay the bill.

The medical profession has as a result become America's new big businessmen. The average income of doctors has now reached $100,000 a year. With such vast incomes the talk in the doctor's surgery is as likely to be about the doctor's latest financial deal, as about whether the minor operation he is recommending at several thousand dollars is entirely necessary.

The rising cost of medicine in the U.S.A. is among the most worrying problem facing the country. In 1981 the country's health cost climbed 15.9 percent—about twice as fast as prices in general.

In the U.S. patients can expect, in medical treatment, ______.

A.occasional mistakes by careless doctors

B.a great deal of personal attention

C.low charge by doctors and hospitals

D.stacking nurses and bad services

It seems like Americans use credit cards for everything. It's a lot easier to spend money
that you don't see, isn't it? Many Americans spend money that isn't even there and get deeper and deeper in debt. Why do so many people spend more than they have? "Buy now, pay later" has become an American way of life. Recently, American households spent nearly 11 billion dollars more than they earned, creating a negative saving rate.

There are two ideas—one, living within your means, and the idea that living on debt is a great equalizer(平衡装置). They both have validity because it is important that someone live within their means over their lifetime. When people are young and they are earning money, but they have very little savings, they almost have to borrow in order to own a house or own a car. But as they grow older, they should develop the habit of saving, so that by the time they reach the end of their earning life, they have savings to live on in retirement, and live within their means.

"Buy now, pay later" worked very well for us in the 1990s, but one suspects it won't work forever. The only thing that concerns me is that Americans are so contented, so optimistic, so unconcerned about any bumps in the road that many American households, not all of them, but many American households are very heavily extended in personal credit, a lot of credit card debt. People are paying very high prices for houses and borrowing heavily against those prices; and if we do run into a bump in the road, a recession, there are going to be a lot of households, not all of them, but many households that Ml be severely squeezed. That means we're more vulnerable to serious financial distress than Japan is. Japan has been in financial distress for ten years, but one reason it's been able to weather that is that the households had been very conservative, had a lot of savings, were very liquid, and were able to weather difficult times. And many American households would now be less able to do that because they are so heavily in debt.

We know from the passage that credit cards

A.make Americans get deeper and deeper in debt

B.are likely to be abandoned by more Americans

C.will soon become a symbol of American life

D.will help solve potential financial problems

Born around 1770 in Tennessee, Sequoyah was a Cherokee.Like otherNative Americans of t

Back then, the Cherokee had no way to write down words in their ownlanguage.Sequoyah believed it was important for the Cherokee to have a systemof writing.So, in 1809, he set out to create an alphabet that the Cherokeecould use to do just that.

Sequoyah started by drawing pictures, with each one representing adifferent word or idea.He soon realized that writing sentences using pictureswould be much too difficult.There were too many words.No one would ever beable to remember that many pictures.

Sequoyah decided to try a different approach.He began to developsymbols to stand for the sounds, or syllables (音节), that made upwords.Twelve years later, he completed a system of writing with 86 differentsymbols.Each one stood for a different syllable in the Cherokee language.Thesymbols could easily be put together to form. words.Soon thousands of Cherokeewere able to read and write in their own language.

Sequoyah's work did not end there, however.He helped to establish aprint shop and began publishing a bilingual newspaper in both Cherokee andEnglish.The shop also printed books translated from English into Cherokee.Inlater years, Sequoyah also became a political leader among the Cherokee.

Some 23 million additional U.S. residents are expected to become more regular users of the
U.S. health care system in the next several years, thanks to the passage of health care reform.Digitizing medical data has been promoted as one way to help the already burdened system manage the surge in patients. But putting people's health information in databases and online is going to do more than simply reduce redundancies. It is already shifting the very way we seek and receive health care.

"The social dynamics of care are changing," says John Gomez, vice president of Eclipsys, a medical information technology company. Most patients might not yet be willing to share their latest CT scan images over Facebook, he notes, but many parents post their babies' ultrasound images, and countless patients nowadays use social networking sites to share information about conditions, treatments and doctors.

With greater access to individualized health information-whether that is through a formal electronic medical record, a self-created personal health record or a quick instant-messaging session with a physician—the traditional roles of doctors and patients are undergoing a rapid transition.

"For as long as we've known, health care has been I go to the physician, and they tell me what to do, and I do it,'" says Nitu Kashyap, a physician and research fellow at the Yale Center for Medical Informatics. Soon more patients will be arriving at a hospital or doctor's office,having reviewed their own record, latest test results and recommended articles about their health concerns. And even more individuals will be able to skip that visit altogether, instead sending a text message or e-mail to their care provider or consulting a personal health record or smart phone application to answer their questions.

These changes will be strengthened by the nationwide shift to electronic medical records,which has already began. Although the majority of U.S. hospitals and doctors' offices are still struggling to start the changeover, many patients already have electronic medical records, and some even have partial access to them. The My Chart program, in use at Cleveland Clinic, the University of Texas Southwestern Medical Center at Dallas and other facilities, is a Web portal (门户)through which patients can see basic medical information as well as some test results.

Medical data is getting a new digital life, and it is jump-starting a "fundamental change in how care is provided," Gomez says.

Which of the following is the best title for this passage?

A.The Future of Your Medical Data.

B.Challenges Against Doctors and Hospitals.

C.Benefits of the U. S. Health Care Reform.

D.How to Access and Share Your Health Information.

What is happening in our weather? Of course we have never been able to predict exactly w
What is happening in our weather? Of course we have never been able to predict exactly what the weather will be like, but now strange weather patterns are seriously affecting many parts of the world. For example, droughts (旱灾) in Mexico and Brazil have recently caused great crop losses and in the United States they have even had to make their own snow for the Winter Olympics!

Scientists have found that the cause of this strange weather is that the air circulation pattern has changed and is now more variable than earlier in the twentieth century. This means that different regions of the world get long spells (持续时间) of the same type of weather, whether hot , cold, wet or windy.

However, weather experts have different views about why this has happened. One theory is that the temperature of the sea has increased. Another is that man’s activities on earth have disturbed the balance of nature.

Whatever the cause, the economics of many countries in the world depend upon the weather. And until we know exactly what effect man’s activities are having on the weather, we cannot make changes which might help. So for the moment the only answer is …wait and see!

26. Which of the following statements is TRUE according to the first paragraph?

A. We have never predicted the weather.

B. Man is now able to control the weather.

C. Strange weather has appeared only in some North American countries.

D. It has always been impossible for man to predict the weather accurately.

27. The strange weather patterns on the earth can he best described as ________.

A. steady and balanced C. likely to cause serious disasters

B. changeable but predictable D. unpredictable but favorable to man

28. The word “affecting” in Paragraph 1 can be replaced by ________.

A. yielding good crops in C. causing few losses in

B. having harmful effects on D. producing desired effects on

29. We can learn from Paragraph 2 that ________.

A. weather patterns are similar in different regions of the world

B. the air circulation pattern remains unchanged in the last century

C. our weather depends on the changes in the air circulation pattern

D. it is possible to predict weather patterns over a long period of time

30. It can be learned from this passage that ________.

A. scientists have similar opinions about the changing weather

B. no one is sure about the cause of the changing weather

C. cutting down forests has affected the climate

D. the weather will become worse in the future
