A

One sixth of undergraduates (本科生) in Beijing this year have registered at a driving school. The students, mostly from majors such as business management or international trade, will finish their driving courses within 20 days or so.

Training costs have dropped to 2,600 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low, but students will accept it, seeing it as an investment in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver’s permit has become another factor.

“In the job market, owning a driver’s permit sometimes strengthens a graduating student’s competitiveness for a good position,” says Zhou Yang, an undergraduate at the China University of Political Science and Law.

Cars will become a necessary part of many people’s lives in the coming years, and it’s difficult to get a permit out of campus because of the pressures on working people’s time. “Having a full-time job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of opportunities to learn.”

Xu Jian, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what it took ordinary people four hours to learn. In this driving school, middle-aged people, young women and college students are the main customers.

To get a driver’s permit, a beginner is now required to have at least 86 hours’ practice before the final road test.

41. The undergraduates are learning to drive because___________.

A. they like to drive cars

B. they need this skill to find a good job.

C. most of them will be able to buy cars in the future

D. they want to become full-time drivers after graduation

42. Which of the following is Xu Jian’s opinion of students learning to drive?

A. He decided it was a waste of money and time.

B. He thought they must learn it at school.

C. He thought they would spend three times more time.

D. He agreed that young people had an advantage in learning to drive.

43. Which of the following would be the best title of this passage?

A. Students Learn to Drive

B. Welcome to Driving School

C. It’s Better to Learn to Drive at College

D. Students Pay Less to Learn to Drive Now

B

Kenya wants to organize a major international conference to discuss how to fight piracy off the coast of Somalia. The conference may also deal with ways to rescue Somalia from seventeen years of civil war. More than forty percent of its people depend on food aid.

Kenyan Foreign Minister Moses Wetangula says the world cannot end piracy without also dealing with Somalia's political problems. He says the piracy is partly born out of a "collective failure" to solve the problems of Somalia. He says the lawlessness there has created a breeding ground for the current threat.

Somali pirates operate in the Indian Ocean and the Gulf of Aden. The Gulf of Aden connects the Red Sea to the Mediterranean by way of the Suez Canal. The pirates have fast boats, modern weapons and equipment like satellite phones and global positioning systems.

The hijacking a week ago of an oil supertanker from off the coast of Kenya has brought new attention to the maritime criminals. Somali pirates have attacked more than one hundred twenty ships this year and hijacked almost forty of them.

The United Nations estimates that pirates have received about thirty million dollars in ransom money for hijacked ships. Kenya's foreign minister says his government believes pirate networks may have earned as much as one hundred fifty million. There are concerns that some of the money could go to Islamic terrorists in Somalia.

Somali pirates generally do not steal goods or kill hostages. They are believed to be holding seventeen ships with about three hundred crew members. Among the ships is a Ukrainian vessel hijacked in September with a load of military weapons including tanks.

The increase in piracy is raising the cost of insuring ships. Also, oil from the Middle East and exports from East Asia could take longer to arrive.

Some of the world's heaviest shipping traffic passes the Somali coast. But major shipping companies have begun to consider new routes. One of the world's biggest shippers, A.P. Moller Maersk, says it will avoid the Gulf of Aden. A move away from the Suez Canal could hurt Egypt's economy.

American and other foreign navy ships are now watching for pirates. This week the Indian Navy destroyed a heavily armed "mother ship" in the Gulf of Aden. But the area to protect covers more than one hundred sixty million square kilometers.

44. According to Kenyan foreign minister, which of the following is not the cause of the piracy in Somalia?

A. The political problems in Somalia.

B. The lawlessness in Somalia.

C. The seventeen years of civil war in Somalia.

D. The Somalia people’s dependence of food aid.

45. According to the passage, what equipment is not used by the pirates in Somalia?

A. Fast boats.                        B. Satellite phones.       

C. nuclear weapons.              D. Global positioning system.

46. According to the passage, which of the following may be the difficulty to fight the privates in Somalia?

A. The area where the pirates may attack the passing ships is so large.

B. The pirates are now considering new routes.

C. Some governments give support to the pirates in Somalia by providing them with money.

D. The pirates are the Islamic terrorists.

47. Which of the following may NOT be the problems the piracy in Somalia cause?

A. The cost of ensuring the safety of the ships is increasing.

B. The Suez Canal and the Gulf of Aden have been destroyed.

C. The money that they got may go to Islamic terrorists in Somalia.

D. Oil from the Middle East and exports from East Asia could take longer to arrive.

C

A woman whose sports car was stolen with her dog in it put up notices all over the area that made it clear getting back her pet was more important than her car.

“Whoever did this can keep my car. Please let Benjerman come home,” the notice said.

It is not known whether the thief showed any pity, but almost 30 hours after the 1 pm theft Friday, Kimberly Atkins of Dover and Benjerman, a 12-year-old black retriever(猎犬), were reunited after police located them in Barrington.

“He’s hungry, he’s dirty, but he’s very happy to be home,” Atkins said.

The car was found at about 5 pm Saturday off Route 125 in a swampy area frequented by off-the-road cars and dirt bikes. However, the police couldn’t control Benjerman, and they had to call Atkins to come and get him.

Atkins said the thief cared for Benjerman a little by providing him with some dry cat food. She believed Benjerman ended up drinking some muddy water in the area. She said they have been together for nearly 11 years after she took him back from a society shelter in Dallas, Texas.

    Before Benjelman was found, Atkins and several friends put up notices all over the city and in Somersworth. They also contacted animal shelters, throughout southern New Hampshire and Massachusetts.

The notice stated there was a reward，and also that the dog needed medication．Any caller could remain anonymous(匿名的).

Atkins had parked the car outside a hardware store with the keys inside and gone in to rent a carpet cleaner.

“It was l0 minutes and I came out and my car was gone along with Benjerman in broad daylight,” Atkins said. The car thief threw Atkins’ wallet and other personal items out of the car before escaping from the scene.

48. What would be the best title for the passage?

A. A car with a dog was stolen

B. Lucky dog was returned to her owner

C. Stealing cars: a most important social problem

D. Woman wants dog back more than stolen car

49. Which of the following shows the correct order of what happened?

a. Notices were put up saying there was a reward.

b. Atkins saw Benjerman again.

c. Police found Atkins’car.

d. Atkins took Benjerman back from a society shelter. 

e. Atkins hired a carpet cleaner in a hardware store.

A. d,e,a,b,c                 B. d,e,a,c,b                C. e,a,d,b,c                  D. e,a,c,d,b

50. We can infer from the passage              ____.

A. the dog was treated extremely badly by the thief

B. car stolen accidents happen frequently nowadays

C. the dog was found because of the reward

D. the thief stole the car easily

51. Which of the following is TRUE according to the passage?

A. Benjerman was sent back immediately after Atkins put up the notices.

C. The thief gave the dog back but kept the sports car.  

D. The dog was back at 1 pm on a Friday.

The oldest forms of medicine are enjoying a comeback. Modern holistic medicine is an approach that treats the whole patient, not just the disease. It is a way to maintain good health rather than cure illness. The most important influences on today’s holistic medicine are ancient Chinese medicine and Indian Ayurvedic medicine, both of which promoted whole body health.

       Holistic medicine usually combines diet, physical exercise and meditation, together with other

alternative techniques such as massage and acupuncture. Herbal treatment, a practice of treating illness by using plants, is influenced by the writings of Culpeper as well as Chinese and Ayurvedic medicine. Homeopathy（顺势疗法）is one of the forms of holistic medicine which is widely practiced in Europe and the USA. Homeopathy began in Germany in the early 1800s, when Samuel Hahnemann described how very tiny doses of a drug had an effect on his patients. According to Hahnemann, the more the drug was diluted (稀释), the stronger its effects. The substance selected would produce similar effects to the disease itself if given in large doses. In the UK homeopathy is regarded as a non-traditional but just about acceptable treatment.

       Meditation and contemplation have an important role in holistic medicine. They were brought to Europe by Indian teachers who combined Indian Ayurvedic medicine with Western beliefs. Transcendental meditation（超脱静坐）is one of the best known of these techniques. People repeat words inside their head to reach a state of deep relaxation.

       The holistic movement has made many doctors look at the whole patient, not just the disease. Life-style, emotional problems and diet are just some of the factors that can affect a person’s health. Holistic medicine emphasizes good diet, exercise and fresh air, all of which contribute to health. Some clinics now offer holistic medicine along with traditional treatments, so that their patients can choose a combination of treatments that suits them. One problem with holistic medicine is that it is difficult for people to be sure that a doctor is reliable. To solve this, many countries want alternative doctors to form professional bodies.

52. Modern holistic medicine centers upon     ______.

A. curing a disease                                    B. herbal treatment

     C. continuous development                         D. keeping patients healthy

53. Which of the following does NOT belong to holistic medicine?

     A. massage                                               B. meditation

     C. a balanced diet                                      D. a knee operation

54. The principle of homeopathy is that     ______.

A. the large doses of medicine that will not be harmful will take better effect

     B. the disease will be cured sooner by taking larger doses of medicine

C. a small thinner dose of medicine will be more effective

     D. the doses of medicine depend on how serious the illness is

55. Which of the following titles best sums up the passage?

     A. Holistic Medicine                                B. Traditional Medicine Returns

     C. History of Medicine                             D. Combination of Treatments Works

56. What can we infer from the passage?

A. Relaxation is the key of holistic treatment.

     B. Holistic medicine needs to become more trustworthy.

     C. Holistic treatment is more beneficial than traditional treatments.

     D. Holistic medicine will become the most welcome treatment soon.

You feel happiest when you create a healthy balance between giving and receiving. If you give and give without making time to fill your own needs, then it’s likely you will burn out, or feel upset. When you take and take without giving anything back, you never feel fulfilled, so you are always searching for ways to fill the void in your life.

       The way to create a healthy balance between giving and receiving is to know and then live by your values. I break values up into two groups which I call being and having values. Your being values are the character traits of the ideal person you would like to be. I suggest to my clients that they choose three being values that they are willing to make a commitment to live by. An example of some being values are: kind, loving, generous, inspirational, peaceful, wise and even powerful. By acting on these values you give to others through your actions and you inspire others by being a positive role model. Mastering being these character traits becomes your life purpose.

       Your having values are the feelings you need to create in order to be happy. These could be companionship, achievement, and support, being valued or financial security. This is what you receive. You take responsibility for filling your own needs by taking steps to create these feelings and conditions in your life.

       When you make a commitment to live by your being values, it becomes easier to make conscious choices rather than reactionary ones. If your usual pattern is to talk about your problems, you could choose to think and act like a calm person. A calm person might go for a walk, meditate (沉思), or set a time limit before responding. If your usual pattern is to worry, you could choose to act like a responsible or wise person. In other words, you would act like the person you choose to be―this is the key to personal power.

       When you choose to act on your values, you not only feel good about yourself, you reinforce（加强）your chosen beliefs. Over time acting in this way changes how you see the world, and in turn the way other people think of you.

57. The main purpose of this passage is to      _____.

A. persuade the readers to make a commitment

B. explain to the readers what personal values are

C. inform the readers how to be truly happy

D. instruct the readers how to make wise choices

58. According to the text, living by your being values, you would      ______.

A. gain a lot of power                        B. form positive personality

C. seek all human virtues                      D. fill your own needs

59. The underlined word “void” in Paragraph 1 means      ______.

A. a feeling of emptiness                      B. an absence of one’s mind

C. a break of continuity                      D. a state of confusion

60. What can be inferred from the text?

A. Having values are better than being values.

B. A calm person does not choose to complain.

C. The way other people think of you decides who you are.

D. A responsible person does not care about financial security.
