AA high school history teacher once told us, "If you make one close friend in school, you will be most fortunate. A true friend is someone who stays with you for life." Experience teaches that he was right. Good friendships are just not easily formed.It is possible that we simply do not stay in one place long enough for a true friendship to develop. However, there can be no disagreement on the need for each of us to think carefully about-the kind of friendships we want.To most of us, friendships are considered very important, but we need to have clear in our own minds the kinds of friendships we want. Are they to be close or kept at arm's length? Do we want to share ourselves or do we want to walk on the surface? For some people, many friendships on the surface are quite enough--and that's all right. But at some point we need to make sure that our expectations are the same as our friends' expectations. If one wants more from the friendship than the other, and if this is not talked about, one is likely at last to feel that he's holding the short end of the stick. The sharing of personal experience including our tears as well as our dark dreams, is the surest way to deepen friendships. But it must be undertaken (进行) slowly and carried on only if there are signs of interest and action in return.What are some of the difficulties to friendship? The greatest is the attraction to expect too much too soon. Deep relationships take time. Another "major difficulty" is the selfishness (自私)In ancient times the most important examinations were spoken, not written. In the schools of ancient Greece and Rome, testing usually consisted of saying poetry aloud or giving speeches.In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study of the subject. This custom exists today as part of the work of testing candidates for a master's or doctor's degree.Generally, however, modern examinations are written. Two types of tests arecommonly used in modern schools. The first type is sometimes called an objective test. It is intended to deal with facts, not personal opinions. To make up an objective test the teacher writes a series of questions each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like answers to students who have not learned the material properly.The student has just one test: he must recognize the correct answer and copy its letter or number on his examination paper.For testing a student's memory of facts and details, the objective test has advantages. It can be scored very quickly by the teacher or even by a machine. In a short time the teacher can find out a great deal about the student's range of knowledge.For testing some kinds of learning, however, such a test is not very satisfactory. A lucky student my guess the correct answer without really knowing the material.to think one "possesses" the other, including his time and attention. Similarly, friendships require actions in return, In other words, you must give as much as you take. Finally there is a question of taking care of. Unless you spend reasonable time together, talking on the phone, writing letters, doing things together, friendships will die away.56. It is not easy for you to make a good friend,A. but, you have to stay in one place waiting for itB. however, only those who stay with you all life could be your true friendsC. however, we need to consider what kind of friendships we wantD. but, everyone needs close friends in lifetime57. Based on the text and your own experience, which of the following statements isan opinion ?A. Social mobility (流动性) prevents the development of friendships.B. Friendships require care.C. In a friendship, you must give as much as you take.D. Deep relationships take time.58. Which of the following statements is false?A. Sometimes we need some friendships on the surface.B. All friendships should be close relationships.C. Absence is harmful to a friendship.D. One should not try to control a friend's life.59. The underlined part "... to feel that he's holding the short end of the stick"here shows thatA. one is about to be hitB. one has a shorter piece of stickC. one has not been treated fairlyD. one has got more from the otherBPearl Carlson was shaken awake at 3:30 a. m. by a forceful pull. King, the family dog, was trying to pull her out of bed, Then she smelled smoke and heard the sound of fire from her parent's room. Pearl's screams awaked her mother, Fern, and father, Howard, who had recently been in hospital for lung disease. Helping Howard to a first-floor window, Fern told him to climb out, then ran to her daughter.Still inside, King appeared at Pearl's window, making squeaking (短促尖叫) sounds. When running toward Pearl's bedroom, Fern realized her husband hadn't yet escaped. She made her way back through the smoke and flames, following King's sound to where Howard lay semiconscious (半昏迷) on the floor. Fern helped him get outside. King came out only after both were safe.As day dawned, the Carlsons saw that King's paws were badly burned, and his entire body was burned too. His chain collar had gotten so hot that it burned his throat, making it impossible for him to bark (叫) normally. Only after the seven-year-old dog refused food did they find pieces of wood in his mouth and realize that King; who slept outside, had bitten through a wood door to warn his family.60. Who was King in this story?A. The family soreB. The family daughter.C. The family dog.D. The master.61. According to the story, the first one who was completely out of danger couldbe .A. HowardB. FernC. Pearl and FernD. Pearl62. After reading this story, we've learnt that the following statements could bereasonable except .A. the dog made a big hole in the doorB. the dog awoke mother firstC. the dog was the last one to escape from the burning roomD. the dog was badly burned and not able to eat63. From this story it can be inferred that .A. Pearl loves her parents very muchB. Howard is the best man of the familyC. the woman loves her children more deeply than her husbandD. the dog is man's best friendCDo you like to eat out? Do you like to eat quickly? Do you like inexpensive food? Some people go to fast-food restaurants for these reasons. In the past, people usually went to diners (小饭馆)for these reasons, too. In fact, many people in the States still go to diners today for the same reasons.A man named Walter Scott had the first "diner" in 1872. It wasn't really a diner. It was only a food cart. People on the street walked up to the cart to buy food. These carts served late- night workers who wanted a cup of coffee and a late-night meal. The meal was a sandwich or boiled eggs. In 1887,Samuel Jones built the first diner big enough to allow the customers to come inside. However, they did not sit down. Later, people built diners with counters and stools, and people sat down while they ate.Before long, many diners stayed open around the clock. In other words, people were able to eat in a diner at any time. Diners changed in other way, too. The original menu of sandwiches and coffee became bigger. It included soup, favorite dishes, and a breakfast menu. In addition, diners soon became permanent buildings. They were nolonger carts on wheels.Diners today look similar to the diners of the early 1900s. They are usually building with large windows. Inside, the diners have shining counters with stools, booths, tables and chairs. People can eat all three meals in a modern diner.Today, many people eat in fast-food restaurants such as Mc Donald's and Burger King. However, the diner remains an American tradition, and thousands of people still enjoy eating there. It was popular a century ago, and it is still popular today.64. What kind of meal did the first "diner" serve?A. Only breakfast.B. Only lunch.C. Only supper.D. All of the above.65. According to Paragraph 3, diners changed in .h. two ways B. three ways C. four ways D. five ways66. Which of the following is NOT true according to the passage?A. Diners existed before fast-food restaurants.B. The menu included more food than sandwiches and coffee.C. Burger King is a fast-food restaurant.D. Sandwiches became bigger.67. The main idea of the passage is that .A. the diner is a traditional, popular place to eat in the United StatesB. Samuel Jones built the first diner big enough to allow the customers to comeinsideC. American diners serve many types of food 24 hours a day to their customersD. diners are different from fast food restaurants in many ways.DYears ago, scientists reported a change in the atmosphere (大气) -- a hole, or thinning of ozone (臭氧) in the atmosphere, over Antarctica. Scientists were not sure what was causing it.Most scientists believe that man-made chemicals are destroying the ozone. But finding the major cause has not helped solve the problem. In fact, experts say the problem seems to be spreading. Scientists also have found signs of ozone loss in otherparts of the atmosphere.Ozone is found both in the air we breathe and in the upper atmosphere. Near the earth, ozone in the air is a danger to life. It is a waste product. But ozone found 10 kilometers to 50 kilometers up in the atmosphere protects life on earth. Ozone forms in the atmosphere through the action of solar (the sun's) radiation. Once formed, the ozone blocks harmful radiation from reaching the earth. Scientists say a reduce in ozone and an increase in the harmful radiation will cause many more cases of skin cancer and will harm crops, animals and fish.Scientists began to study the condition of ozone in the atmosphere in March 1988. The report said temperatures in the hole are getting colder. It is about eight degrees colder 15 kilometers above earth than it was in 1979. Scientists think the first loss of ozone reduce the amount of solar energy the atmosphere can take in. This cools the atmosphere, increases ice cloud production and leads to more ozone loss.Another report said that scientists found signs the ozone problem has spread. The study shows that the loss of ozone over the areas with larger population in North America and Europe was at least three times greater than scientists had thought. The ozone levels reduced much more seriously during winter months than in warmer months. This is not surprising, because the amount of ozone in the atmosphere changes with the temperature.Why has the ozone problem developed? No one knows for sure. An international effort is being made to stop the loss of ozone in the atmosphere. But many experts fear the effort will not produce results fast enough to prevent harm to life on earth.68. This text is mainly aboutA. a change in the atmosphereB. solar radiationC. the ozone problemD. the ozone form69. According to the text, which of the following statements is true?A. Ozone in the atmosphere is a danger to life.B. Since ozone in the air is very harmful to life, the less ozone in the atmospherethe better.C. Ozone is only a kind of man-made chemical product.D. The ozone in the atmosphere can stop harmful radiation from getting to theearth.70. The loss of ozone may be caused by the following conditions except forA. the amount of solar energyB. the colder temperatureC. the larger populationD. man-made chemicals71. From the text, we've learnt thatA. the scientists have found exactly what was causing the loss of ozoneB. the temperatures in 1979 are much colderC. ozone holds on solar energy and helps atmosphere take it inD. efforts have been made to stop the loss of ozone successfullyEThe oil resources which are left will not last very long. This means that all vehicles such as cars, trains, buses, planes and ships that need oil to work will not be able to run. So it will be necessary to develop a new system of transport which uses a fuel other than oil. Electric vehicles are one possibility. In Britain, most families have at least one car and this car is used everyday. It could be that only one person in the family drives the car to work or for shopping. The number of cars on the road which are almost empty perhaps helps to explain why the oil is used up so quickly. The family car is a very useful form of transport but it is also a great waste of energy, especially if it is compared with buses or trains. Much petrol is used by a car which is traveling at 120 kilometers an hour. Clearly, it would be better if there were fewer cars on the road and more speed limits so that the oil which is left will last as long as possible.About 25% of Britain' s total consumption (消耗) of energy is domestic--it is used only in the home. Just over 20% is used for transport. Most of the energy is used in industry. It is difficult to suggest any possible energy conservation(保护) in industry because many of the suggestions would mean that some people would lose their jobs. It is important that industry produces the same amount of productsusing the same amount of workers.Obviously, conservation is not going to the answer to the energy crisis. The most it can do is to give more time for a better solution to be found. The more time which is available for new sources of energy to be developed, the better it is because there is still a lot of work to be done in order to find suitable, safe methods of producing energy.72. In Britain, what reason could help to explain why oil is used up very quickly?A. People use cars every day.B. Most families have at least one ear.C. Many cars on the road are almost empty.D. People drive their cars to work.73. Which of the following is true?A. Compared with buses and trains, the family car is useful and can save energy.B. A car driving at the speed of 80 kilometers per hour uses half as much petrol asa car traveling at 160 kilometers per hour.C. It is possible for people to develop vehicles.D. Limitation of the number of cars on the road and their speed will help the oillast longer.74. What does the underlined word "domestic' mean in paragraph two?A. For household use.B. On the road.C. Slow driving.D. Fast driving.75. What is better way to solve the problem of the energy crisis?A. Governments should cut down the number of family cars on the road.B. The speed of vehicles must be limited.C. New sources of energy should be found and developed.D. Factories should cut down on production.第II卷(共35分)第四部分:写作共两节,满分36分)第一节:短文改错(共10小题;每小题1分,满分10分)此题要求你对一段文章改错。
