广东省广州市执信中学2016届高三上学期英语期末测试

阅读下列短文,从每题所给的四个选项中,选出最佳选项。

The health-care economy is filled with unusual and even unique economic relationships. One of the least understood involves the peculiar roles of producer or “provider” and purchaser or “consumer” in the typical doctor-patient relationship. In most sectors of the economy, it is the seller who attempts to attract a potential buyer with various appealing factors of price, quality, and use, and it is the buyer who makes the decision. Such condition, however, is not common in most of the health-care industry.

In the health-care industry, the doctor-patient relationship is the mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician — and even then there may be no real choice — it is the physician who usually makes all significant purchasing decisions: whether the patient should return “next Wednesday”, whether X-rays are needed, whether drugs should be prescribed, etc. It is rare that a patient will challenge such professional decisions or raise in advance questions about price, especially when the disease is regarded as serious.

This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of the decisions, but in general it is the doctor's judgments that are final. Little wonder then that in the eye of the hospital it is the physician who is the real “consumer”. As a consequence, the medical staff represents the “power center” in hospital policy and decision-making, not the administration.

Although usually there are in this situation four identifiable participants— the physician, the hospital, the patient, and the payer (generally an insurance carrier or government) — the physician makes the essential decisions for all of them. The hospital becomes an extension of the physician; the payer generally meets most of the bills generated by the physician/hospital, and for the most part the patient plays a passive role. We estimate that about 75-80 percent of health-care choices are determined by physicians, not patients. For this reason, the economy directed at patients or the general is relatively ineffective.

(1)、The author's primary purpose in writing this passage is to ________.

A、urge hospitals to reclaim their decision-making authority B、inform potential patients of their health-care rights C、criticize doctors for exercising too much control over patients D、analyze some important economic factors in health-care
(2)、It can be inferred that doctors are able to determine hospital policies because ________.

A、most of patient's bills are paid by his health insurance B、it is doctors who generate income for the hospital C、some patients might refuse to take their physician's advice D、a doctor is ultimately responsible for a patient's health
(3)、According to the author, when a doctor tells a patient to “return next Wednesday”,  the doctor is in fact ________.

A、advising the patient to seek a second opinion B、warning the patient that a hospital stay might be necessary C、instructing the patient to buy more medical services D、admitting that the first visit was ineffective
(4)、The author is most probably leading up to ________.

A、a proposal to control medical costs    B、a study of lawsuits against doctors for malpractice C、an analysis of the cause of inflation (通货膨胀) in the US D、a discussion of a new medical treatment

 There are an extremely large number of ants worldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior.

         In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone (外激素), chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.

         In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.

         Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from itsindividual parts.

    Looking at China's history over the past 60 years,it is apparent that,despite much suffering,the country has achieved huge political,economic and social success,especially during the past three decades.

    The press center for the celebration of the 60th founding anniversary of new China was officially opened on the morning of September 22. Zha Shouchen,deputy director of the press center introduced that,during the National Day,there would be 3,200 domestic reporters,and more than 1,300 foreign journalists to come to Beijing to make the covering work.

    The press center provided many services for domestic and foreign reporters,such as issuing the press cards to reporters,accepting the interview application,organizing press conferences and activities of group interviews,providing the means of communication and information services for reporters.And the following was the scene.

    A grand parade in Beijing on Oct.1,led by the People's Liberation Army and the People's Armed Police Force,showed some of China's latest achievements in defense modernization.About 8,000 military officers,along with tanks and other vehicles,formed a straight line stretching 3 kms.

    The military parade was followed by a civilian parade featuring six massive performing groups and 36 formations of about 100,000 people.In addition,60 floats(彩车)represented everything from the country's geographic areas to the previous year's Beijing Olympics.

    Everyday life in China is a parade on a grand scale,with citizens now being able to enjoy things their ancestors did not dare to contemplate 100 years ago,things their grandparents took for luxury 60 years ago,and things their parents did not even know how to attempt 30 years ago.

    WeChat is a social mobile application with voice and text messaging timeline and several social features like ‘Message in a Bottle'. WeChat, a popular instant messaging tool run by Tencent Holdings, aims to help users access mobile services without downloading separate apps, which experts said may challenge the business of smartphone app distributors such Apple Store.

This new feature, named ‘Mini Programs', allows WeChat users to find a variety of services such as ticket buying by scanning a QR (quick-response) code, saving them the trouble of installing a number of different apps on smart devices, according to the transcript of a speech by Zhang Xiaolong, Tencent's senior executive vice president, on Wednesday. The new function is expected to come online on January 9.

    Zhang, known as the father of WeChat, emphasized that ‘Min Programs' is not a mobile app distributing function.

    Still, experts and app developers said that the rollout (推出) of ‘Mini Programs' on WeChat will erode the market share of app distributors like Apple Store in China.

     “‘Mini Programs' will attract lots of start-ups, because a program based on WeChat can help them build up businesses at much lower costs,” a Shanghai-based app developer, told the Global Times Wednesday.

    If a start-up wants to promote its business via a separate application, it has to hire a special team to develop two different apps— one each for iOS and Android.

    Lsiunched in 2011, WeChat has evolved to include services such as ‘Order Taxi', ‘Food Delivery', e-commerce and payments from just an instant messaging app.

                                                                                 Is There Life on Earth

    There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

    The satellite was directed into an area known as Manhattan(named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20,000 light years ago). Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to the feasibility(可行性)of a manned flying saucer(飞碟)landing on Earth. A press conference was held at the Venus Institute of Technology.

    “We have come to the conclusion, based on last week's satellite landing,” Pro. Zog said, “that there is no life on the Earth.”

    “How do you know this?” the science reporter of the Venus Evening Star asked.

    “For on thing, Earth's surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive.”

    “What does this mean as far as our flying saucer program is concerned?”

    “We shall have to take our own oxygen with us, which means heavier flying saucer than we originally planned.”

    “Are there any other risks that you discovered in your studies?”

    “Take a look at his photo. You see this dark black cloud floating over the surface of Earth?” We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

    “If what you say is true, won't this set back the flying saucer program several years?”

    “Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”

    “Pro. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?

    “Because if we Venusians can learn to breathe in an Earth atmosphere, then. We can live anywhere.”

    If humans pump enough carbon dioxide (CO2) into the atmosphere, the stratocumulus clouds(层积云) could disappear, and the earth's temperature could climb sharply to heights not predicted in current climate models. It would burn the planet. That's the conclusion of a paper published in the journal Nature Geoscience and described in detail by Natalie Wolchover for Quanta Magazine.

    As Wolchover explained, clouds have long been one of the great uncertainties of climate models. Computer models that easily capture the complexity and detail of most climate systems just aren't powerful enough to predict worldwide changes in cloud behavior. But clouds are important. They reflect sunlight away from the earth's surface. And stratocumulus clouds are those white blankets you might have seen as you looked out the window of arm airplane, rolling out below you and hiding the ground Researchers suspect that certain sudden, past jumps in temperature may have been caused by changes to clouds like these.

    For the new research, scientists modeled just a small patch of sky using a supercomputer. They found that if carbon dioxide levels reach about 1, 200 parts per million(ppm) in the atmosphere, stratocumulus clouds break up. That's a very high carbon dioxide concentration.  Right now, levels have climbed past 410 ppm--a dangerous change from 280 ppm before the Industrial Revolution.

    But humans put more and more CO2 into the atmosphere every year. If current trends continue, the earth could reach 1, 200 ppm within 100 to 150 years. This could happen if our society doesn't follow through on any of its commitments to reduce emissions(排放), Wolchover reported. And even if it does, the result would be another 8 degrees Celsius of heat added to the global average, on top of the dangerous changes already underway due to greenhouse gases.

    That's an enormous change, and it goes beyond predictions of worldwide ice melt and catastrophic sea level rise. And, once the stratocumulus clouds are gone, Wolchover reported, they likely wouldn't reappear until atmospheric carbon dioxide levels dropped below where they are currently.

    There's still some uncertainty in the data. The 1, 200 ppm figure could change as scientists look into the issue further.

    Scientists in New Zealand have found fossilized (化石的) leg bones from a penguin believed to have been about the size of an adult human. The previously undiscovered giant penguin species likely stood about 1.6 meters tall and weighed up to 80 kilograms.

    The penguin existed about 60 million years ago. The bones are believed to be from the oldest of several species of giant penguins that lived after dinosaurs died out. A fossil hunter found the bones last year in the Waipara River bed near the city of Christchurch. The bones are from the animal's legs and feet. Scientists confirmed that the bones came from a newly discovered species.

    Paul Scofield is senior curator (馆长) at New Zealand's Canterbury Museum. He co-wrote a paper on the discovery. He said that the bones are an important find. They show that the species is similar to another giant penguin found in Antarctica in 2000. The latest discovery, he said, helps show a clear connection between the two areas during the Paleocene period. This period lasted from 66 million to 56 million years ago.

    Scofield said the penguins were able to grow larger after entering a new development period following the extinction of dinosaurs, sea reptiles and huge fish. Scofield added that the giant penguins became extinct within 30 million years, as large mammals began to rule the waters.

    John Cockrem is a penguin expert at the country's Massey University who was also not involved in the research. He said the discovery helps add to what we know about giant penguins. He said it also confirmed New Zealand as the penguin center of the world.

    New Zealand is believed to have been home to many giant bird species that later disappeared. These included the world's largest parrot, a giant eagle and an emu-like bird called the moa. Recently, Canterbury Museum announced the discovery of an unusually large parrot believed to have lived about 19 million years ago. Scientists say the bird stood about one meter tall.
