He moved there a few years ago, and I was eager to see his new place and meet his friends.My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him. He seemed unhappy with me if I didn’t got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to try ha rd to think out things to say, feeling on guard.On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.31. Why did the author feel bitter(痛苦) about her father as a young adult?A. He was silent most of the time.B. He was too proud of himself.C. He didn’t love his children.D. He expected too much of her.32.

The underlined words in the last paragraph refer to ________.A. the author’s sonB. the author’s fatherC. the friend of the author’s fatherD. the cafe owner35. We can infer from the passage that ________.A. the writer's father used to be strict with her when he was a childB. the writer's father worked hard but cared less for his familyC. it was possibly the first time that the writer had visited her father's new homeD. as a child, the writer loved her fatherBEveryone has got two personalities—the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to upset people, so you never express your real feelings. You’re quite shy and you aren’t very confident.If you sleep on your stomach, you are a rather secretive(不坦率的)person. You worry a lot and you’re always easily upset. You’re very stubborn(顽固的), but you aren’t very ambitious. You’re usually live for today not for tomorrow. This means that you enjoy having a good time.If you sleep curled up (卷曲),you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel anxious, but you don’t often get depressed. You always say what you think even if it annoys people.36. According to the writer, you naturally show your secret and real personality .A. only in a normal nightB. only when you go to sleepC. only when you refuse to show yourself to the wordD. only when you change sleeping position37. Which is NOT mentioned in the second paragraph about a person’s personality?A. He or she is always open with others.B. He or she always likes new ideas earlier than others.C. He or she is always easily upset.D. He or she tends to believe in others.38. Point out which sentence is used to show the personality of a person who is used to sleeping on his or her stomach?A. He or she is careful not to offend others.B. He or she doesn’t want to stick to his or her opinion.C. He or she can’t be successful in any business.D. He or she likes to bring others happiness.39. Which of the following may be the reason for you not to make friends with a person who sleeps curled up?.A. He or she would rather be alone than communicate with you.B. He or she is rarely ready to help you.C. He or she prefers staying at home to going out.D. He or she wouldn’t like to get help from you.40. It appears that the writer tends to think highly of the person who sleeps on one side because .A. he or she always shows sympathy for peopleB. he or she is confident, but not stubbornC. he or she has more strengths than weaknessesD. he or she often considers annoying peopleCFirst of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult (侮辱). For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn't in the sandwich, but in the way students deal with the conflict.Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution (解决) stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words, name-calling, and accusation only add fuel to the emotional fir On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control.After both sides have calmed down, they can use another key strategy for conflict resolution; listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non-threatening questions to clarify the speaker's position. Then the two people should change roles.Finally, students need to consider what they are hearing. This doesn't mean trying to figure outwhat's wrong with the other person. It means understanding what the real issue is and what both sides are trying to accomplish. For example, a shouting match over a peanut butter sandwich might happen because one person thinks the other person is unwilling to try new things. Students need to ask themselves questions such as these: How did this start? What do I really want? What am I afraid of ? As the issue becomes clearer, the conflict often simply becomes smaller. Even if it doesn't, careful thought helps both sides figure out a mutual solution.There will always be conflict in schools, but that doesn't mean there needs to be violence. After students in Atlanta started a conflict resolution program, according to Educators for Social Responsibility, "64 percent of the teachers reported less physical violence in the classroom; 75 percent of the teachers reported an increase in student cooperation; and 92 percent of the students felt better about themselves". Learning to resolve conflicts can help students deal with friends,. teachers. parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country.41. This article is mainly about__________.A. the lives of school childrenB. the cause of arguments in schoolsC. how to analyze youth violenceD. how to deal with school conflicts42. From Paragraph 2 we can learn that________ .A. violence is more likely to occur at lunchtimeB. a small conflict can lead to violenceC. students tend to lose their temper easilyD. the eating habit of a student is often the cause of a fight43. Why do students need to ask themselves the questions stated in Paragraph 5?A. To find out who to blame.B. To get ready to buy new things.C. To make clear what the real issue is.D. To figure out how to stop the shouting match.44. After the conflict resolution program was started in Atlanta, it was found that______.A. there was a decrease in classroom violenceB. there was less student cooperation in the classroomC. more teachers fell better about themselves in schoolsD. the teacher-student relationship greatly improved45. The writer’s purpose for writing this article is to_______.A. complain about problems in school educationB. teach students different strategies for school lifeC. advocate teaching conflict management in schoolsD. inform teachers of the latest studies on school violenceⅣ、阅读选择（每小题2分，共10分，其中2项为多余选项）Time is the most valuable thing that mankind has. 46 Many people try to manage their time. They arrange information and tips in order to effectively do so.47 Time can be managed easily by finding out what is important and arranging these things in the order of importance. In this way you know your direction before making any plans and do not waste time and energy unnecessarily.Now comes the next question. 48 The answer is that you need to find out what stepsyou need to take to do and what you want to do. Then you know how much time to spend for each thing. These steps are like goals.49 Not having them is like walking blindly in a dark room, trying to find the door.
