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.

All the useful energy at the surface of the earth comes from the activity of the sun. The
sun heats and feeds creatures and mankind. Each year it provides men with two hundred million tons of grain and nearly ten million tons of wood.

Coal, oil, natural gas, and all other fuels are stored energy from the sun. Some was collected by this season's plants as carbon compounds. Some was stored by plants and trees ages ago. Even waterpower derives from the sun. Water turned into vapor by the sun falls as rain. It courses down the mountains and is converted to electric power. Light transmits only the energy that comes from the sun's outer layer, and much of this energy that is directed towards the earth never arrives. About nine tenths of it is absorbed by the atmosphere of the earth. In fact, the earth itself gets only one half millionth of the sun's entire output of radiant energy.

The sun is the source of all of the following EXCEPT______.

A．gasoline

B．natural gas

C．atomic power

D．animal fat

Even waterpower derives from the sun. Water turned into vapor by the sun falls as rain. It courses down the mountains and is converted to electric power.

Light transmits only the energy that comes from the sun' s outer layers, and much of this energy that is directed toward the earth never arrives. About nine-tenths of it is absorbed by the atmosphere of the earth. In fact; the earth itself gets only one half-billionth of the sun' s entire output of radiant energy.

All the useful energy at the surface of the earth comes ______.

A．directly from the sun

B．from the sun' s activity

C．from energy stored by the sun

The largest shark known to us, Megalodon, is extinct. Or is it？ Carcharodon Megalodon, com
monly known as Megalodon, is believed to have lived between I million and 5 million years ago and thought to have been 52 feet long. It is (or was) a shark that had a jaw 7 or more feet wide. Fairly recently, there has been some speculation about whether it is extinct or just out of reach. But few people believe that Megalodon has found a home deep in the ocean.

There are many known "Living Fossils": Coelacanth, Sea Cucumbers, Sea Urchins, Lobsters, Sea Stars. The common ones like lobsters and sea urchins are not really looked on as anything amazing. They've been around for thousands of years or more, and axe easily accessible to us. What if they weren't accessible and yet still existed？ We would label them extinct. The discovery of a live Coelacanth, a fish long believed extinct, challenged some scientists' long-held beliefs on extinction. There have been recent discoveries Of incredibly large squid, and deep-sea fish never before seen by scientists.

In the 1960s the U.S. Navy set up underwater microphones around the world to track Soviet submarines. The network, known as the Sound Surveillance System, still lies deep below the ocean's surface in a layer of water known as the "deep sound channel'. The temperature and pressure of the channel allow sound waves to travel undisturbed. NOAA's Acoustic Monitoring Project has been using the Sound Surveillance System to listen for changes in ocean structure like ocean currents or volcanic activity. Most of the sounds recorded are common and of no concern. One sound, identified in 1977 by U.S. Navy "spy" sensors, was odd. It was obviously a marine animal but the call was more powerful than any of the calls made by any other reported sea creature. It was too big for a whale. Could it be a deep-sea monster？ One possibility was a giant squid, but no one is sure. It was named "Bloop". Could it be Megalodon？ If Megalodon is still alive down in the bottom of the ocean, we may some day soon discover it. Then what？ Deep sea diving will never be the same, that's for sure!

The following is commonly known EXCEPT ________.

A．Megalodon, the largest shark, is extinct

B．Megalodon is not extinct but just out of reach

C．Megalodon was 52 feet long and had a jaw 7 or more feet wide

D．Megalodnn lived between several million years ago

Passage Two America put more people in prison in the 1990s than in any decade in its his

Passage Two

America put more people in prison in the 1990s than in any decade in its history. That started a debate over the wisdom of spending billions of dollars to keep nearly 2 million people locked up. According to statistics, the United States ends 1999 with 1983084 men and women in prisons. That shows an increase of nearly 840,000 prisoners during the 1990s and makes the United States the country with the highest prisoner population in the world. With the cost of housing a prisoner at about $20,000 a year the cost in 1999 for keeping all these prisoners behind bars is about $39 billion.

Some experts argue that the money is well spent, saying the cost of keeping prisoners behind bars doesn't seem much in comparison in the 1990s coincided with (与……相一致) a steady drop in the US crime rates. It is reported that serious crime has decreased for seven years in a row. "There are noticeable number of people who don't do crimes because they don't want to go to prison," they say.

36. There is a heated debate among American experts because ______.

A. America has put 2 million people in prison

B. the cost for housing a prisoner keeps rising

C. billions of dollars has been spent on prisoners

D. the prisoner population is the largest in the world

Part A

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)

Menorca or Majorca？ It is that time of the year again. The brochures are piling up in travel agents while newspapers and magazines bulge with advice about where to go. But the traditional packaged holiday, a British innovation that provided many timid natives with their first experience of warm sand, is not what it was. Indeed, the industry is anxiously awaiting a High Court ruling to find out exactly what it now is.

Two things have changed the way Britons research and book their holidays: low-cost airlines and the Internet. Instead of buying a ready-made package consisting of a flight, hotel, car hire and assorted entertainment from a tour operator's brochure, it is now easy to put together a trip using an online travel agent like Expedia or Travelocity, which last July bought Lastminute. com for ￡ 577 million ($1 billion), or from the proliferating websites of airlines, hotels and car-rental firms.

This has led some to sound the death knell for high-street travel agents and tour operators. There have been upheavals and closures, but the traditional firms are starting to fight back, in part by moving more of their business online. First Choice Holidays, for instance, saw its pre-tax profit rise by 16% to ￡ 114 million ($195 million) in the year to the end of October. Although the overall number of holidays booked has fallen, the company is concentrating on more valuable long-haul and adventure trips. First Choice now sells more than half its trips directly, either via the Internet, over the telephone or from its own travel shops. It wants that to reach 75% within a few years.

Other tour operators are showing similar hustle. MyTravel managed to cut its loss by almost half in 2005. Thomas Cook and Thomson Holidays, now both German owned, are also bullish about the coming holiday season. Highstreet travel agents are having a tougher time, though, not least because many leading tour operations have cut the commissions they pay.

Some high-street travel agents are also learning to live with the Internet, helping people book complicated trips that they have researched online, providing advice and tacking on other services. This is seen as a growth area. But if an agent puts together separate flights and hotel accommodation, is that a package, too？

The Civil Aviation Authority (CAA) says it is and the agent should hold an Air Travel Organisers Licence, which provides financial guarantees to repatriate people and provide refunds. The scheme dates from the early 1970s, when some large British travel firms went bust, stranding customers on the Costas. Although such failures are less common these days, the CAA had to help out some 30,000 people last year. The Association of British Travel Agents went to the High Court in November to argue such bookings are not traditional packages and so do not require agents to acquire the costly licences. While the court decides, millions of Britons will happily click away buying online holidays, unaware of the difference.

Based on the first paragraph, the best title of the text could be______.

A．An annual holiday

B．A High Court ruling

C．A new package

D．A British innovation

Section B

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.

The planet's wild creatures face a new threat—from yuppies (雅皮士), empty nesters and one parent families.

Biologists studying the pressure on the planet's dwindling biodiversity today report on a new reason for alarm. Although the rate of growth in the human population is decreasing, the number of individual households is exploding.

Even where populations have actually dwindled in some regions of New Zealand, for instance— the numbers of individual households has increased, because of divorce, career choice, smaller families and longer lifespan.

Jianguo Lin of Michigan State University and colleagues from Stanford University in California report in Nature, in a paper published online in advance, that a greater number of individual households, each containing on average fewer people, meant more pressure on natural resources.

Towns and cities began to sprawl (蔓生，蔓延) as new homes were built. Each household needed fuel to heat and light it; each household required its own plumbing, cooking and refrigeration.

"In larger households, the efficiency of resource consumption will be a lot higher, because more people share things," Dr Liu said. He and his colleagues looked at the population patterns of life in 141 countries, including 76 "hotspot' regions unusually rich in a variety of local wildlife. These hot spots included Australia, New Zealand, the US, Brazil, China, India, Kenya, and Italy. They found that between 1985 and 2000 in the "hotspot" parts of the globe, the annual 3.1% growth rate in the number of households was far higher than the population growth rate of 1.8%.

"Had the average household size remained at the 1985 level," the scientists report, "there would have been 155 million fewer households in hotspot countries in 2000.

Dr Liu's work grew from the alarming discovery that the giant pandas living in China's Wolong reserve are more at risk now than they were when the reserve was first established. The local population had grown, but the total number of homes had increased more swiftly, to make greater inroads into the bamboo forests.

Only around 1.75 million species on the planet have been named and described. Biologists estimate that there could be 7 million, or even 17 million, as yet to be identified. But human numbers have grown more than sixfold in the past 200 years, and humans and their livestock are now the greatest single consumer group on the planet. The world population will continue to soar, perhaps leveling off around 9 billion in the next century. Environmental campaigners have claimed that between a quarter and a half of all the species on earth could become extinct in the next century.

Biologists report that the biodiversity is decreasing because ______.

A．more individual households are increasing greatly

B．human beings are threatening many wild creatures

C．human populations have been decreasing in recent years

D．wild creatures depend on more individual households

Population tends to grow at an exponential（指数的)rate. This means that they progressively

Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.

World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.

Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.

This passage chiefly discusses______.

A．the growth of world population

B．one type of the exponential rate

C．the population problem of more rapidly growing countries

D．the possible ways of dealing with the rapid population growth

听力原文：There student thieves look out. Students can easily get many research papers off

听力原文： There student thieves look out. Students can easily get many research papers off the Internet. A new Website could help teachers catch copiers.

Some students research and write their term papers. Others, however, just copy them off the Internet and turn them in as their work.

Two graduate students at the University of California at Berkeley have written a program to catch the students who copy. It compares a student's paper with every other term paper on the Web.

A hundred million Web pages on the Internet are searched. The top 20 search engines are used for the search. This service can be found at www. Plagiarism.com. They also have a local database of term papers. Teachers who sign up can send their students' 'papers to the Website. Within 24 hours they know if the student did the work. Every sentence that was a word-for-word match with another sentence either found on the Internet or within our database is coded.

A U. C. Berkeley professor told his class he would use the program. Still some students copied papers. All 300 papers went through the program. In 45 papers or 15 percent of students had cut and pasted large amounts of material from different World Wide Websites.

Students that say they didn't copy can defend themselves. They can show the instructor where they got their material. Students at universities try hard to get good grades. Some students welcome the Internet research watchdog because they say it is fair to all. They think copying is wrong.

Instead of researching and writing their papers, some students ______.

A．ask other students to write their papers

B．draw pictures instead

C．copy from reference books

D．copy papers or large parts of papers from the Internet

About 70 million Americans are trying to lose weight. That is almost 1 out of every 3 peop
le in the United States. Some people go in diet. This means they eat less of certain foods, especially fats and sugars. Other people exercise with special equipment, take diet pills, or even have surgery. Losing weight is hard work, and it can also cost a lot of money. So why do so many people in the United States want to lose weight？

Many people in the United States worry about not looking young and attractive. For many people, looking good also means being thin. Other people worry about their health. Many doctors say being overweight is not healthy. But are Americans really fat？

Almost 30 million Americans weigh at least 20 percent more than their ideal weight. In fact, the United States is the most overweight country in the world. "The stored fat of adult Americans weighs 2. 3 trillion (兆) pounds, " says University of Massachusetts anthropologist (人类学家) George Armelagos. He says burning off that stored energy would produce enough power for 900, 000 cars to go 12, 000 miles.

Losing weight is hard work, but most people want to find a fast and easy way to take off fat. Bookstores sell lots of diet books. These books tell readers how to lose weight. Each year, dozens of new books like these are written. Each one promises to get rid of fat.

Which of the following is NOT mentioned as a way of losing weight？

A．To eat less fats and sugars.

B．To have surgery.

C．To take much exercise.

D．To work hard.

［A］ For example, the Moche lords of Sipán in coastal Peru were buried in about AD

400 in fine cotton dress and with exquisite ornaments of bead, gold, and silver. Few burials rival their lavish sepulchres. Being able to trace the development of such rituals over thousands of years has added to our understanding of the development of human intellect and spirit.

［B］ By 40,000 years ago people could be found hunting and gathering food across most of the regions of Africa. Populations in different regions employed various technological developments in adapting to their different environments and climates.

［C］ Archaeological studies have also provided much information about the people who first arrived in the Americas over 12,000 years ago.

［D］ The first fossil records of vascular plants—that is, land plants with tissue that carries food—appeared in the Silurian period. They were simple plants that had not developed separate stems and leaves.

［E］ Laetoli even reveals footprints of humans from 3.6 million years ago. Some sites also contain evidence of the earliest use of simple tools. Archaeologists have also recorded how primitive forms of humans spread out of Africa into Asia about 1.8 million years ago, then into Europe about 900,000 years ago.

［F］ One research project involves the study of garbage in present-day cities across the United States. This garbage is the modern equivalent of the remains found in the archaeological record. In the future, archaeologists will continue to move into new realms of study.

［G］ Other sites that represent great human achievement are as varied as the cliff dwellings of the ancient Anasazi (a group of early Native Americans of North America) at Mesa Verde, Colorado; the Inca city of Machu Picchu high in the Andes Mountains of Peru; and the mysterious, massive stone portrait heads of remote Easter Island in the Pacific.
