Northern Europeans spend a lot of time in their cold and cloudy winters planning their summer holidays. They are proud of their healthy color when they return home after the holiday. But they also know that a certain amount of sunshine is good for their bodies and general health.

In ancient Greece people knew about the healing(治疗) powers of the sun, but this knowledge was lost. At the end of the nineteenth century a Danish doctor, Niels Finsen, began to study the effect of sunlight on certain diseases, especially diseases of the skin. He was interested not only in natural sunlight but also in artificially (人造地) produced rays. Sunlight began to play a more important part in curing sick people.

A Swiss doctor, Auguste Rollier, made full use of the sun in his hospital at Lysine. Lysine is a small village high up in the Alps. The position is important: the rays of the sun with the greatest healing power are the infra-red (红外线的) and ultra-violet (紫外线的) rays; but ultra-violet rays are too easily lost in fog and the polluted air near industrial towns. Dr. Roller found that sunlight, fresh air and good food cure a great many diseases. He was particularly successful in curing certain forms of tuberculosis with his “sun-cure”.

There were a large number of children in Dr. Roller’s hospital. He decided to start a school where sick children could be cured and at the same time continue to learn. It was not long before his school was full.

In winter, wearing only shorts, socks and boots, the children put on their skis after breakfast and left the hospital. They carried small desks and chairs as well as their school books. Their teacher led them over the snow until they reached a slope which faced the sun and was free from cold winds. There they set out their desks and chairs, and school began.

Although they wore hardly any clothes, Roller’s pupils were very seldom cold. That was because their bodies were full of energy which they got from the sun. But the doctor knew that sunshine can also be dangerous. If, for example, tuberculosis is attacking the lungs, unwise sunbathing may do great harm.

Today there is not just one school in the sun. There are several in Switzerland, and since Switzerland is not the only country which has the right conditions, there are similar schools in other places.

1. According to the passage, when did sunlight begin to play a more important part in the treatment of disease?

A. From ancient times.        B. At the end of the nineteenth century.

C. Not until this century.              D. Only very recently.

2. Why are a Danish doctor and a Swiss doctor mentioned in the second and third paragraphs?

A. Because they both made use of sunlight to treat illness.

B. Because they were the first people who used sunlight for treatment.

C. Because they were both famous European doctors.

D. Because they used sunlight in very different ways.

3. Dr Roller set up a “sun-cure” school probably for the reason that _______.

A. most children could stay in his hospital

B. children could study while being treated

C. the school was expected to be full of pupils

D. the school was high up in the mountains

4. What can be inferred from the last paragraph of the passage?

A. “Sun-cure” schools are becoming popular everywhere.

B. Switzerland is the only country where “sun-cure” schools are popular.

C. Proper conditions are necessary for the running of a “sun-cure” school.

D. “Sun-cure” schools are found in countries where there is a lot of sunshine.

“Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American’s exports soon after it went on the air in New York in 1969.

In the United States more than six million children watch the program regularly. The viewers include more than half the nation’s pre-school children, from every kind of economic(经济的), racial(种族的), and geographical group.

Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.

Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional(偶然的) viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.

The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.

Why has “Sesame Street” been so much more successful than other children’s shows? Many reasons have been suggested. People mention the educational theories(理论) of its creators, the support by the government and private(私人的) businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.

1. “Sesame Street” is actually _______.

A. a street in the US            B. a program for children

C. a program for teachers      D. a program for students

2. Children who often watch the program _______.

A. can have problems in school    

B. will find it a great help

C. will take no interest in their studies

D. will be well educated

3. What is special about the program?

A. It offers great fun.

B. It makes children feel able to learn.

C. It is shown at different hours during the week.

D. Children learn and enjoy themselves while watching.

4. Why is “Sesame Street” so popular in the world?

A. Because it is supported by the government and businesses.

B. Because it uses a variety of skillful tricks.

C. Because mothers watch it along with their children.

D. Because it makes every child watching it feel able to learn.

5. The best title for this passage can be _______.

A. TV Programs                                 B. Educating Children

C. Sesame Street                                D. A Great Success

The space shuttle Columbia flared and broke up in the skies over Texas on Saturday, February 1,2003, killing the seven astronauts on board in what NASA and President Bush called a tragedy for the entire nation. NASA launched an investigation into the disaster and began searching for the astronauts' remains. It said that although there had been some data failures it was too early to nail down a precise cause. The break-up, 16 minutes before the shuttle was due to land at Kennedy Space Center in Florida, spread possibly toxic debris(有毒的残骸) over a wide swath of Texas and neighboring states.

Dramatic television images of the shuttle's descent clearly showed several white trails(痕迹) streaking through blue skies after the shuttle suddenly fell apart. It was almost 17 years to the day that the Challenger shuttle exploded on Jan. 28, 1986, killing all seven astronauts on board.

Take-off and re-entry into Earth's atmosphere are the most dangerous parts of a space mission. In 42 years of US' human space flight, there had never been an accident in the descent to Earth or landing. Challenger exploded just after take-off.

Rescue teams scrambled to search for the remains of the crew, which included the first Israeli to fly on the shuttle, former combat pilot Col. Ilan Ramon. There were warnings that parts of a vast 120-mile-long corridor of debris could be toxic because of poisonous rocket propellant(推进器).

"We are not ready to confirm that we have found any human remains," Nacogdoches County Sheriff Thomas Kerrs said. He added that among the roughly 1,000 calls reporting debris, some people said they found remains of crew members.

"The Columbia is lost. There are no survivors, …Their mission was almost complete and we lost them so close to home. … America's space program will go on," said a grim-faced Bush in a message broadcast on television, which included condolences to the families of the dead astronauts.

1. The word “descent” in the passage means ________.

A. taking off   B. landing      C. orbiting     D. walking down

2. Which is true of the Israeli astronaut Ilan Ramon?

A. He was the first Israeli astronaut to fly on the shuttle.

B. He was the first foreign astronaut to fly on the American shuttle.

C. He used to be a passenger plane pilot.

D. He was the only survivor in the Columbia disaster.

3. The Columbia disaster and the Challenger disaster were similar in that ________.

A. there were seven astronauts killed on board

B. both the shuttles exploded when they took off

C. Both the shuttles exploded when they were about to land

D. no human remains were found

4. Which of the following is wrong according to the news?

A. The U.S.A. will give up the space program because of the accident.

B. NASA hasn’t found the cause of the Columbia disaster.

C. Before the Columbia disaster, no shuttles had exploded in the course of landing.

D. Take-off and re-entry into Earth's atmosphere are the most dangerous parts of a space mission.

Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to this hospital, which usually charges patients according to the number of days they stay and the facilities(operating room, tests, medicines that they use). Some hospitals belong to a city, a state or, in the case of veteran's hospitals, a federal government agency. Others are operated by religious orders(教会) or other non-profit groups.

Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service.

Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would be physicians first attend college for four years, which can cost nearly $ 20 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $ 10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency(实习阶段) in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low.

Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.

Physicians work long hours and must accept a great deal of responsibility. Many medical procedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.

1. According to the passage, it is very unlikely that an American hospital is owned by _______.

A. a church     B. a corporation     C. a city         D. a state

2. The expenses for becoming a doctor are spent on _______.

A. schooling and retraining          B. practice in a hospital

C. facilities he or she uses            D. education he or she receives

3. According to the passage, how long does it take for a would-be physician to become an independent physician in the USA?

A. About seven years.                  B. Eight years.

C. Ten years.                               D. About twelve years.

4. Sometimes several physicians set up a group medical practice mainly because _______.

A. there are so many patients that it is difficult for one physician to take care all of them

B. they can take turns to work long hours

C. facilities may be too much of a burden for one physician to shoulder

D. no one wants to assume too much responsibility

5. Which of the following statements could fully express the author's view towards physicians’ payment in the USA?

A. For their expensive education and their responsibility, they deserve a handsome pay.

B. It is reasonable for physicians to have a large income because their work is very dangerous.

C. Physicians should be better paid because they work long hours under bad conditions.

D. Physicians have great responsibility, so it is understandable that they should be well rewarded.

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.

The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?

During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.?

In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.?

At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?

If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?

No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(症状).?

1. The writer offered _______ examples to support his argument.?

A. 4             B. 5            C. 6             D. 3

2. Which of the following does not agree with the chosen passage??

A. The Eskimos do not suffer from colds all the time.?

B. Colds are not caused by cold.?

C. People suffer from colds just because they like to stay indoors.?

D. A person may catch a cold by touching someone who already had one.

3. Arctic explorers may catch colds when ________.

A. they are working in the isolated Arctic regions?

B. they are writing reports in terribly cold weather?

C. they are free from work in the isolated Arctic regions?

D. they are coming into touch again with the outside world

4. The passage mainly discusses ________.

A. the experiments on the common cold  

B. the fallacy about the common cold?

C. the reason and the way people catch colds

D. the continued spread of common colds
