Knowing the best way to study will help you to be a better student. By using your time properly, you can do your homework more quickly. Learning to study is not difficult.

The first thing to remember is that you must be willing to learn. It doesn’t mean that you must always like the subject. It does mean, however, that you must be wil1ing to do whatever is necessary to learn. Try to understand why it is important and how it will help you now and later to do and learn other things. Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier. Sometimes the subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them.

Here’s some advice for you:have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on your study without interruptions(中断); have everything ready before you sit down to study, a dictionary, paper, a pen and books; be

sure you understand what you should learn before you start; read carefully and pay special attention to the most important things; when memorizing, first find out the main parts and then recite the whole thing; check your homework after you finish it; never forget the importance of review and preview.

Don’t try to spend a lot of time researching learning methods. There are many students who know many good learning methods but don’t study well. They forget that the most useful learning method is to study hard.

41. The main goal of the article is .

A. to prove that learning is not difficult

D. to tell the students how to study well

D. we like the subjects

44. The following advice is given in the article EXCEPT .

My elder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult.

For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had soared through Mrs. Holt’s basement window, breaking the glass with a crash, Steve encouraged me to confess(承认)to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball. I also learned from Steve that personal property is a sacred(神圣的) thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I’d hate to lose to someone else the small dog that my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on my shoulder.

Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind. When I was twelve, I killed an old brown sparrow in the yard with a BB gun. Excited with my accuracy, I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, “Did it hurt you first, Mark?” I didn’t know what to answer. He continued with his eyes firm, “The only time you should even think of hurting a living thing is if it hurts you first. And then you think a long, long time.” I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.

46. What is the main subject of the passage?

A. The relationship between Mark and Steve.

B. The important lesson Mark learned in school

C. Steve’s important role in mark’s growing process.

D. Mark and Steve’s respect for living things.

47. It can be inferred from the passage that when Mark confessed to Mrs. Holt, __________.

A. he felt surprised

B. he was light-hearted

C. he felt frightened

D. he knelt before her

48. In the story about the pen, which of the following lessons did Steve teach his brother?

A. Respect for personal property.

B. Respect for life.

C. Sympathy for people with problems.

D. The value of honesty.

49. According to the writer, which was the most important lesson Steve taught his young brother?

A. Respect f or living things.

B. Responsibility for one’s actions.

C. The value of the honesty.

D. Care for the property of others.

50. Which of the follow is true according to the passage?

B. Mark lost the small dog his father carved somewhere.

C. When a living thing hurts you, you should kill it.

D. Even if a living thing hurts you, you should not kill it without hesitation.

C

I began to grow up that winter night when my parents and I were returni ng from my aunt’s house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.

I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving and never to come back was hardly in my head then.

The four years that followed taught me the importance of optimism(乐观), but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time

passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times.”

My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers (移民局官员), took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.

From my experiences I have learned one important rule:Almost all common troubles go away at last! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.

51. The author got to know America from __________.

A. radio programs

B. books and pictures

C. her mother

D. her relatives

52. Upon leaving for America the author felt __________.

A. excited

B. confused

C. worried

D. amazed

53. For the first two years in New York, the author __________.

A. often lost her way

B. did not think about her future

C. studied in three different schools

D. got on well with her stepfather

54. We can learn about the author from Paragraph 4 that__________.

A. she worked as a translator.

B. she attended a lot of job interviews.

C. she paid telephone bills for her family.

D. she helped her family with her English.

55. The author believes that __________.

A. her future will be free from troubles

D. good things will happen if one keeps trying

D

In the early stages of skill or character development, imitation(模仿) is helpful. When I first learned to cook, I used recipes (菜谱) and turned out some tasty dishes. But soon I grew bored. Why follow someone else’s way of cooking when I could create my own? Imitating role models is like using training wheels on a child’s bicyc le; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.

In daily life, imitation can hurt us if we subconsciously (下意识地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.

In the field of entertainment, those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.

Think of the movies, books, teachers, and friends that have affected you most deeply. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.

56.Imitation proves useful when you .

A. know you are unique

B. lose the balance of life

C. begin to learn something new

D. get tired of routine practice

57. To avoid the bad result of imitation, we should________.

A. forget daily fear and pain

B. choose the right example

C. ask others for decisions

D. stay away from stars

58. According to the author, the world moves on because of those who are .

A. eager to influence others with their knowledge

B. ready to turn their original ideas into reality

C. eager to discover what their ancestors did

D. willing to accept others’ ideas

59.The trouble a creator faces is .

A. the lack of strong motivation

B. the absence of practical ideas

C. how to search for more materials

D. how to use imagination creatively

60. The author’s purpose in writing this passage is to __________.

A. emphasize the importance of creativity.

B. criticize the characters of role models.

C. compare imitation with creation.

D. explain the meaning of success.

This hotel in the trees is famous in the world. Peop1e who know very little about Kenya, know of Treetops. When King George VI died, Princess Elizabeth was staying on the Treetops, and when she came down from there, “She succeeded him as the queen of the country”.

[1] I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day. But I became invisible, absent from the conversation.

[2] The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Recently I was in a car with three friends. The driver told us to be quiet because he could not hear the person on the other end of his cell phone. There we were, four friends going down the highway, unable to talk to one another because of a tool designed to make communication easier.

[3]Why is it that the more connected we get, ________________________ ? Every advance in communications technology is a hurt to the closeness of human interaction (互动). With e-mail and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone.

[4] More and more, l find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up because I didn’t really have time to talk. The industry devoted to helping me keep in touch is making me lonelier.

[5] So I've put myself on technology restriction:no instant messaging with people who live near me, no cell-phoning in the presence of friends, no letting the voice mail pick up when I' m home.
