“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.

Botany, the study of plants, occupies a special position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest (含糊的) of insight. It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of peoples, not only for food, but also for clothing, weapons, tools, eyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognized accurately hundreds of plants and know many properties of each. To them, botany, as such, has no name and is probably not even recognized as a special branch of knowledge at all.

    Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer productions the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the wonder of agriculture; cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the built up knowledge of tens of thousands of years of experience and close relationship with plants in the wild would begin fade away.

Which of the following statements about early humans is expressed in the passage?

A. They probably had extensive knowledge of plants.

B. They thought there was no need to cultivate crops.

C. They did not enjoy the study of botany.

D. They placed great importance on the ownership of property.

What does the comment “This is logical.” In the first paragraph mean?

A. There is no clear way to determine the extent of our ancestor’s knowledge of plants.

B. It is not surprising that early humans had a detailed knowledge of plants.

C. It is reasonable to assume that our ancestors behaved very much like people in pre-industrial societies.

D. Human knowledge of plants is well organized and very detailed.

According to the passage, why has general knowledge of botany begun to fade?

A. People no longer value plants as a useful resource.

B. Botany is not recognized as a special branch of science.

C. Research is unable to keep up with the increasing numbers of plants.

D. Direct contact with a variety of plants has decreased.

In the second paragraph, what is the author’s purpose in mentioning “ a rose, an apple, or an orchid”?

 A. To make the passage more poetic.

 B. To give an example of plant that are attractive.

 C. To give botanical examples that all readers will recognize.

 D. To explain the variety of botanical life.

According to the passage, what was the first great step toward the practice of agriculture?

A. The invention of agricultural tools and machinery.       

B. The development of a system of names for plants.

C. The discovery of grasses that could be harvested and replanted.

D. The changing diets of early humans. 

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.

A. About seven years.                  B. Eight 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.
