  The American cowboy was a great national hero through facts and stories.

  In history, the real cowboy was a simple farm worker on horseback. He spent twelve to fourteen hours a day outdoors working with cows. The work was dirty, tiresome and not very well paid. In winter, most cowboys had to find other jobs. They were seldom alone. Most of them worked in teams of eight to ten.

  People could raise beef cattle at low cost in the western states and send them by train to the eastern markets. Hut someone had to look after the cattle on the open land and get them to the nearest railroad . This was the job of a cowboy. Sometimes the railroad was more than a thousand kilometers away and it could take as long as six months to move the cattle. The cowboy moved the cattle slowly so that the cattle would not lose weight.

  Most cowboys were young, unmarried men. A cowboy's horse was his most important tool. A good horse made the job of moving cattle much easier. A good cowboy understood cows and knew how to control them. At night, he sang to the cows to keep them calm .

  The cowboy quickly received popular praise. Historians say that was because the cowboy appeared during a time of change in American life. In the late 1800's, America was changing from a nation of farms to one of factories and cities. The cowboy seemed free and more independent than other Americans.

  Today, the life of real cowboys has changed greatly. One change has been the use of trucks. There is no need for the modem cowboy to sleep on the ground. Modem cowboys are better paid. They are likely to be married. Today cowboys are found in almost every state of the United States . Some of them are farmers or teaches or truck drivers . Some work for big companies. But at night and on weekends they became cowboys. Most have less than a thousand cows, and some have only two or three, those part-time cowboys increase the total production of meat, keeping beef price low. Most modem cowboys do not make much money from raising cattle. Many do it because they love the cowboy life.

[  ]

A.was covered with dirt

2.Sometimes it took the cowboys ________ to move the beef cattle from the western states to the eastern markets.

[  ]

A.in the western parts of the United States

B.in the eastern markets every year

C.in the time of great changes in America

D.in the early 1800's

閱讀理解

  Psychology(心理學)has a new application in the field of medicine.Many doctors, together with their patients, are looking for alternative methods of treatment of physical problems.In large hospitals, modern therapy(療法)seems to focus on the physical disease.Patients may feel they are treated like broken machines.Some doctors have recognized this as a problem.They are now using psychological therapy, in which the patient is working with the doctors against the disease with the help of medicine.The patient does not wait for the medicine and treatment to cure him or her, but instead the patient joins in the fight.

  The doctor knows that a disease affects a patient's body physically.The body of the patient changes because of the disease.He is not only physically affected, but also has an emotional response to the disease.Because his mind is affected, his attitude and behavior change.The medical treatment might cure the patient's physical problems, but the patient's mind must fight the emotional ones.For example, the studies of one doctor, Carl Simonton, M.D., have shown that a typical cancer patient has predictable attitudes.She typically feels depressed, upset, and angry.Her constant depression makes her acts unfriendly toward her family, friends, doctors, and nurses.Such attitudes and behaviors prevent recovery.Therefore, a doctor's treatment must help the patient change that.Simonton's method emphasizes treatment of the “whole” patient.

  The attitude of a cancer patient receiving radiation therapy, an X-ray treatment, can become more positive.The physician who is following Simonton's psychological treatment plan suggests that the patient imagine that he or she can see the tumor(腫瘤)in the body.In the mental picture, the patient "sees" a powerful beam of radiation like a million bullets of energy.The patient imagines the beam hitting the tumor cells and causing them to shrink.For another cancer patient, Dr.Simonton asks him to imagine the medicine going from the stomach into the bloodstream and to the cancer cells.The patient imagines that the medicine is like an army fighting the diseased cells and sees the cancer cells gradually dying and his blood carry away the dead cells.Both the medical therapy and the patient's positive attitude fight the disease.

  Doctors are not certain why this mental therapy works.However, this use of psychology does help some patients because their attitudes about themselves change.They become more confident because they use the power within their own minds to help stop the disease.

  Another application of using the mind to help cure disease is the use of suggestion therapy.At first, the doctor helps the patient to concentrate deeply.The patient thinks only about one thing.He becomes so unaware of other things around him that he is asleep, or rather in a trance(催眠狀態).Then the physician makes “a suggestion” to the patient about the medical problem.The patient's mind responds to the suggestion even after the patient is no longer in the trance.In this way, the patient uses his mind to help his body respond to treatment.

  Doctors have learned that this use of psychology is helpful for both adults and children.For example, physicians have used suggestion to help adults deal with the strong pain of some disease.Furthermore, sometimes the adult patient worries about her illness so much that the anxiety keeps her from getting well.The right suggestions may help the patient to stop being anxious.Such treatment may help the patient with a chronic(慢性的)diseases.Asthma(哮喘)is an example of a chronic disorder.Asthma is a disease that causes the patient to have difficulty in breathing.The patient starts to cough and sometimes has to fight to get the air that he or she needs.Psychology can help relieve the symptoms of this disorder.After suggestion therapy, the asthma patient breathes more easily.

  Physicians have learned that the psychological method is very useful in treating children.Children respond quickly to the treatment because they are fascinated by it.For example, Dr.Basil R.Collison has worked with 121 asthmatic children in Sydney, Australia, and had good results.Twenty-five of the children had Excellent results.They were able to breathe more easily, and they did not need medication.Another forty-three were also helped.The symptoms of the asthma occurred less frequently, and when they did, they were not as strong.Most of the children also felt better about themselves.Doctors have also used suggestion to change habits like nail-biting, thumb-sucking, and sleep-related problems.

  Many professional medical groups have accepted the medical use of psychology and that psychology has important applications in medicine.

(1)

What does the passage mainly discuss?

How suggestion therapy benefits adults and children.

How modern therapy focuses on the disease.

C.

Responses from the medical world.

D.

How to use the mind against disease.

D.

The patient uses his mind to cure himself.

(3)

What can we learn from the studies of Carl Simonton, M.D.?

[  ]

A.

The medical treatment can cure the patient's mental disease.

B.

The treatment of a patient by treating the body and the mind is necessary.

C.

The mental treatment is more important than medical treatment.

(A)

Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(獨特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn’t need in order to travel lighter?

Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.

The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.

1. The ordinary woman’s leather shoe is considered unusual because _______. 

A. it was an important clue to life in the past B. it was found on a famous trail

C. it at one time belonged to a VIP             D. it was a fashionable shoe at that time

2. According to this passage, many people who went to Alaska _______. 

A. eventually became millionaires              B. brought with them many shoes

C. had conflicts with the Eskimos               D. were not properly equipped

3. The Canadian government made gold seekers bring one year’s supplies with them so that _______.

A. they would not die of hunger and cold

B. the army would have enough food for fighting a war

C. they would change these goods with the Eskimos

D. the supplies would make Alaska rich

4. No matter what happened to the woman who owned the shoe, _______. 

A. she must have lived a happy life

B. she certainly dropped the shoe on purpose

C. her adventurous spirit is definitely admired

D. her other shoes were equally fashionable

(B)

Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free!

It’s “no”.

What do you ask? We’ll say it again: “No”.

Sweet and simple “no”.

Say “no” at your office and see how quickly that pile of work on your desk disappears.

“Saying ‘no’ to others means you are saying ‘yes’ to yourself, ” said Leslie Charles, a professional speaker from East Lansing, Michigan.

“Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can’t say ‘no’.”

Susie Watson, a famous writer, said people who always say “yes” need to say “no” without guilt(內疚)or fear of punishment. “I would rather have someone give me a loving ‘no’ than an obligated(強制的) ‘yes’, ” she said.

Susie Watson says she feels “no” obligation to give an explanation when she says “no” either socially or professionally. Does she feel guilty about it? “Not at all, ” said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Conneticut. “Most people are afraid of saying ‘no’… My advice is to say ‘yes’ only if you don’t mean ‘no’.”

Watson said “no” is the most effective weapon against wasting time. “Every year there are more demands on your time… Other people are happy to use up your time, ” Watson said. Time saving appears to be “no’s” greatest friend.

“No” can be your new friend, a powerful tool to take back your life. “No” may even take you further in the business world than “yes”.

“No” is power and strength. “No” now seems completely correct. “Saying ‘no’ isn’t easy. But finally it’s greatly liberating,” Charles said. But, he added, a “no” project needs to be worked on every day because it is hard to change long-term habit.

But, he also warns: “Don’t go to extremes. Don’t find yourself saying ‘no’ to everything. In return you should learn to hear ‘no’.”

5. The sentence “Saying ‘yes’ to yourself” means _______.

A. you can have more time to play with others

B. you needn’t care about other’s feeling if you are happy

C. you are selfish and treat others rudely

D. you can deal with your business as you have planned

6. When you say “no” to others you should say it in a _______.

A. secret way   B. polite way

C. proud way     D. guilty way

7. In Watson’s opinion, people can save much time on condition that _______.

A. they say “no” at a suitable time

B. they say “no” as much as possible

C. they are afraid of saying “no”    

D. they make others angry at them

8. If a person says “no” to everything, the result he or she receive may be that he or she _______.

A. enjoys a wonderful life     B. makes a lot of money

C. faces difficulty in life  D. forgets to say “yes” in the end

(C)

A characteristic of American culture that has become almost a tradition is to respect the self-made man — the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.

    This attitude toward manual(體力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪華地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.   

9. From paragraph 1, we can know that in America _________.

A. people tend to have a high opinion of the self-made man

B. people can always rise to the top through their won efforts

C. college professors win great respect from common workers

D. people feel painful to mention their fathers as labors.

10. According to the passage, the hostess cooks dinner herself mainly because _________.

A. servants in American are hard to get

B. she takes pride in what she can do herself

C. she can hardly afford servants

D. It is easy to prepare a meal with canned food

11. The expression “ wait on table” in the second paragraph means “_________”.

A. work in a furniture shop         B. keep accounts for a bar

C. wait to lay the table                D. serve customers in a restaurant

12. Which of the following may serve as the best title of the passage?

A. A Respectable Self-made Family       B. American Attitude toward Manual Labor

C. Characteristics of American Culture      D. The Development of Manual Labor

(E)

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物種). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

17. The aim of “Noah’s Ark” project is to _______.

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

18. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.

A. available panda eggs         B. host animals

C. qualified researchers            D. enough money

19. The best title for the passage may be _______.

A. China’s Success in Pandas Cloning                                 

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas

D. China —the Native Place of Pandas Forever

20. From the passage we know that _______.

A. Kraemer and his team have succeeded in cloning a dog

B. scientists try to implant a panda’s egg into a rabbit

C. Kraemer will work with Chinese scientists in clone researches

D. about two thousand of species will probably die out in a century
