       We come by business naturally in our family. Each of the seven children in our family worked in our father’s store.  21  we worked and watched, we learned that work was about more than  22  and making a sale.

       One lesson stands out in my  23  . It was shortly before Christmas. I was in eighth grade and was working in evenings, straightening the toy section. A little boy, five or six years old, came in. He was  24   a brown torn coat with dirty sleeves. His shoes were scuffed and his one shoelace was torn. The little boy looked poor to me ― too poor to  25  to buy anything. He looked  26  the toy section, picked up this item and  27 , and carefully put them  28  in their place.

       Dad came down the stairs and walked over to the boy. His steel blue eyes  29  and the dimple(酒窝)in his cheek stood out as he asked the boy what he could do for him. The boy said he was looking for a Christmas 30  to buy his brother. I was impressed that Dad treated him with the same respect as any adult. Dad told him to take his  31  and look around. He did.

       After about 20 minutes, the little boy carefully picked up a toy  32 , walked up to my dad and said, “How much for this, Mister?”

       “How much you got?” Dad asked.

       The little boy held out his hand and  33  it. His hand was creased(起皱) with  34  lines of dirt from holding his  35   too tightly. In his hand  36  two dimes, a nickel and two pennies―27 cents. The price on the toy plane he’d picked out was $3.98.

       “That’ll just  37  it,” Dad said as he  38  the sale. Dad’s reply still  39  in my ears. When the little boy walked out of the store, I didn’t notice the dirty, worn coat or the single torn shoelace. What I saw was a happy child with a  40  .

第二部分:阅读理解(第一节20小题;第二节5小题;每小题2分,满分50分)

       阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

       A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutchmen in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.

       The Dutch research is one of three human studies that give strong scientific support to the long-held belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption average more than 3 ounces

       For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.

       During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol levels.

41.The passage is mainly about           .

       A.the high incidence of heart disease in some countries

       B.the changes in people’s diet

       C.the daily fish consumption of people in different culture.

       D.The effect of fish eating on people’s health

 

 

42.We can infer from the passage that there are fewer heart disease deaths         .

       A.in the countries with good production of fish

       B.in the countries of the yellow-skin race

       C.in the countries with high consumption of fish

       D.in highly-developed countries

43.The underlined part “This relationship” may refer to the connection between        and

       the level of heart disease.

       A.the amount of fish eaten                 B.regular fish-eating

       C.the kind of fish eaten               D.people of different areas

44.In which section of a newspaper can we read this passage?

       A.Ads.               B.Movies.          C.Briefs.            D.Health and diet.

       The Internet is a way of life for US college students, with research showing them to be one of the most connected groups.

       A recent study by Harris Interactive and 360 Youth found that 93 percent of American college students visit the Internet, and this market is expected to grow from 15.2 million in 2003 to 16.4 million in2007.

       That is slow but could be the result of the already high number of college Internet users.

About 88 percent of American college students own a computer, and more than half have broadband connections. Furthermore, 76 percent own cell phones and 36 percent use their mobile devices to visit the Internet.

       Study findings are that 42 percent go online mainly to communicate socially, and 72 percent of college students check emails at least once a day, with 66 percent using at least two email addresses.

       The most popular online social activity is forwarding messages to friends or family, with 37 per cent of college students saying they do so.

       The study also looked beyond the Internet surfing habits and into the buying habits of this group, and found them responsible for more than US$210 billion in sales last year alone.

       College students have learned how to spend their money, with 93 per cent saying low prices were important when shopping.

       The study also showed that 65 percent make loan payments, 41 percent of freshmen have a credit card; and 79 percent of seniors have a credit card.

       A significant number of charges on those credit cards are likely to be for entertainment and leisure expenses.

 

 

 

 

 

45.College students in the US, as this passage shows,         .

       A.don’t have to learn their lessons in their classroom

       B.spend too much time visiting the Internet

       C.lead an exciting life by visiting the Internet

       D.waste much time visiting the Internet

46.From the fourth paragraph we can find that in the US          .

       A.most college students are from rich families

       B.college students can have a computer from their college

       C.cell phones will take the place of computers in college

       D.mobile phones make Internet life easy for college students

47.To communicate with friends, nearly half of the college students use           .

       A.letters               B.e-mails           C.telephones       D.telegraphs

48.By using the Internet, college students in the US can do the following except        .

       A.reading newspapers                   B.chatting with friends

       C.buying goods                        D.going swimming

       "Tear’em apart!" "Kill the fool!" "Murder the referee(裁判)!"

       They are common remarks one may hear at various sporting events. At the time they are made, they may seem innocent(无害的)enough. But let's not kid ourselves. They have been known to influence behavior in such a way as to lead to real bloodshed(流血).Books have been written about the way words affect us. It has shown that words having certain meanings may cause us to react in ways quite foreign to what we consider to be our usual humanistic behavior. I see the term "opponent" as one of those words. Perhaps the time has come to delete it from sports terms.

    The dictionary meaning of the term "opponent" is "enemy":“ one who opposes your interests." Thus, when a player meets an opponent, he or she may tend to treat that opponent as an enemy. At such times, winning may control one's mind, and every action, no matter how bad, may be considered correct . I recall an incident in a handball game when a referee refused a player's request for a time out for a glove change because he didn't consider them wet enough. The player rubbed his gloves across his wet T-shirt and then shouted, "Are they wet enough now?"

    In the heat of battle, players have been observed to throw themselves across the court without considering the consequences that such a move might have on anyone in their way. I have also witnessed a player reacting to his opponent's intentional and illegal blocking by hitting him with the ball as hard as he could during the course of play. Off the court, they are good friends. Does that make any sense? It certainly gives proof of a court attitude which is different from normal behavior.

       Therefore, I believe it is time we promoted the game to the level where it is by setting an example. Replacing the term “opponent” with “ associate” could be an ideal way to start.

    The dictionary meaning of the term “associate” is “friend”;“companion.” Think it over!You may soon see and possibly feel the difference in your reaction to the term "associate' rather than "opponent."

49.Which of the following statements best expresses the author's view?

    A.Bad behavior in sports will always have serious consequences.

       B.The words people use can influence their behavior.

    C.Unpleasant words in sports are often used by foreign athletes.

    D.Unfair judgments by referees will lead to violence on the sports field.

50.Rough words are spoken during games because the players________.

    A.are too eager to win                   B.are usually bad-tempered

    C.can't afford to be polite in competitions  D. their friends as competitors

51.What did the handball player do when he was not allowed a time out to change his gloves?

    A.He refused to continue the game.

    B.He angrily hit the referee with a ball.

    C.He claimed that the referee was unfair.

    D.He wet his gloves by rubbing them across his T-shirt

52.The author hopes to have the current situation in sports improved by_______.

    A.changing the attitude of players on the sports field

    B.raising the referee's sense of responsibility

    C. on players to use clean language on the court

    D. the relationship between players and referees

       First it was jogging. Then aerobics(有氧运动). Not too long ago, Americans discovered race walking.

       Now Americans are into a new fitness craze. They’re taking up bicycling. Over hills and down mountainsides and across quiet country roads, Americans are busily rolling along.

       The number of adults who ride for fitness is around 17 million, an increase of 70 percent over four years ago. Twice as many women as men are coming to the sport. Americans are falling in love with biking because it has speed, the benefits of jogging and beautiful scenery.

       Bicycling is a very appropriate sport, which is important to people who injured their knees while jogging or whose joints are aching from aerobics. And biking is a real awakening for people who have been into race walking in the past. Race walking is as dull as watching paint dry.

       The most popular kind of bicycle for people who are new to the sport is the mountain bike, which has a fixed frame with wide tires and upright handles. Mountain bikes also have many gears to make it easier to climb hills. About 5 million Americans ride mountain bikes, compared with 200,000 who rode them only five years ago.

       Costs range from about $130 for a bottom-of-the-line bicycle to more than $2,700 for an expensive bicycle.

       Mountain biking has attracted some people who race down the sides of mountains like a bat out of hell. But most riders ride slowly and they rarely venture far from home.

       The biking craze has brought an unexpected profit to clothing and bicycle accessory makers. Last year, bikers paid $630 million for biking clothes and accessories.

Bicycling seems likely to continue its fantastic growth.

53.Race walking is about as dull as watching paint dry because           

       A.race walking is a slow-moving sport

       B.the number of adults who ride for fitness has grown 70 percent in four years.

       C.it has speed, the benefits of jogging and beautiful scenery.

       D. are taking up bicycling.

54.The bicycling craze has been a profit for            .

       A.people who want to ride like a bat out of hell

    B. accessory makers

       C.race walkers                               

       D.twice as many women as men

55.What does the underlined word “bottom-of-the-line” mean?

       A.poor                 B.modern           C.old                D.cheapest

56.The main idea of the article is _______

       A.riding a bicycle is one of the most dangerous sports in America

       B.Americans are rolling along

       C.bicycling is the latest fitness craze to hit America

       D.most people in America want to own a hand-made bicycle that can cost more than 2,700

       Many children first learn the value of money by receiving an allowance(pocket money). The purpose is to let children learn from experiences at an age when financial mistakes are not very costly.

       The amount of money that parents give to their children to spend as they wish differs from family to family, Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.

       In any case, parents should make clear what , if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. 

       The object is to show young people that a budget demands a choice between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics. Many people who have written on the subject of allowances say it is not a good idea to pay you child for work around the home. These jobs are a normal part of family life.      

       Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works.

       Allowances give children a chance to experience the three things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save it.

       Saving helps children understand that costly goals require sacrifice. You have to cut costs and plan for the future. Requiring children to save part of their allowances can also open the door to future saving and investing . Many banks offer services to help children and teenagers learn about personal finance.

       A saving account is an excellent way to learn about the power of compound interest .

       Compounding works by paying interest,So, for example , one dollar invested at two percent interest for two years will earn two cents in the first year. The second year, the money will earn two percent of one dollar and two cents, and so on. That may not seem like a lot, But over time it adds up.

57.Giving an allowance, parents should consider all the following EXCEPT      

       A.how much the child should get each time

      B.whether the child has made a budget

C.where the money really goes           

D.how often a child can get it

58.According to the passage, how can a child learn to have a budget?      

       A.Through their own experiences.            B.Through parents’ instruction.

       C.By spending allowance.                        D.By receiving allowance. 

59.The author of the passage holds the opinion that        .

       A.what children learn by handling allowances may be beneficial in the future

       B.children can learn to set up their own business with their allowances

       C.keeping allowances in the bank is the best choice for children

       D.it is not a good idea to pay children to do housework at home 

60.What is the best title for the passage?       

       A.Be Generous To Pay Your Children

       B.Be Wise To Avoid Financial Mistakes

       C.Saving Allowances Does Good To Children

       D.Allowances Help Children Learn About Money

61.Mike is a student of medicine. Besides learning the science of diagnosing(诊断), treating,

       or preventing disease and other damage to the body or mind, he has to learn medical

       English because he needs it since he will work in an English-speaking country after

       graduation. Furthermore, he has to know something about the health care system of the

       country, which will be helpful to his career.

 

62.Joseph is good at the language arts, and in his spare time he likes to learn the English

       language. He will soon have his summer vacation of four weeks. So he is now planning to

       take a course to develop his English skills such as speaking, writing, listening and reading.

       He wants to gain a certificate as for proof of his English level when completing the course

       of study. He’d like to teach English as a foreign or second language in the near future.

63.Anna, a French high school girl, has been learning English since she was a little girl, and she

       has got a good achievement in the examination of IELTS. She will enter a university after

       graduation. So she wants to take the opportunity of the vacation to further her English study

       because the university she has applied for requires perfect English. She feels the need to

       improve her English skills.

64.Jane, a middle school student, has learnt some English, but she doesn’t know how her

       English level is. She has to take an exam checking to see her English level before entering

       an English course. And she will choose a course to learn to speak and write in English

       during the period of about nine months.

65.Susan is a student of medicine. She has planned to go to a health care unit after graduation.

       She is told that English is a must for those who want to work for the health care. So she is

       going to take a course of both English and medicine or health care.

       The Summer Institute for Medical English(SIME)

       The Summer Institute for Medical English is a program tailored to the needs of junior medical students in their first 2 or 3 years of study. The SIME program provides students with the unique opportunity to learn medical English, clinical skills, meet Canadian medical students and gain exposure to the Canadian health care system through the observation of health professionals in Canada.

第一节:

The main purpose of newspapers is to provide news. If you examine newspapers closely, you will find there are all sorts of news: accidents, floods, fires, wars, sports, books, etc. The news covers everything ^that/which happens to people and their surroundings. Sometimes there is some news which is very interesting. A news report is usually short, except when it is very important, but has a lot of information. It is also written in short paragraphs. The first paragraph is in the fact a summary of the news. It gives all the necessary information, what, when, where, how, and why.

第二节:

Opinions are divided on the problem about whether we should buy products promoted by a star.

Some students say that they prefer to buy products promoted by a star because most of them care about the quality of the products they are going to advertise. Besides, buying those products is a way to support the stars they like.

However, others express their opposite opinions. They think what some stars really care when they make an advertisement is money but not the quality of the product. In addition, the product that a star advertises is not necessarily suitable for everyone.

In my opinion, we should be cool and sensible while choosing a product. The main aspect we are supposed to consider is not the advertisement or the star but the quality of products and their real usefulness in our daily life.
