They have such long，long necks!

Don't you think it's cruel to bring giraffes over from Africa to Europe？Don't you think it's cruel to keep them in the zoo？Tom：Well，I enjoyed seeing them today．But in Africa they would have miles and

（加利福尼亚州）wildfire started on Tuesday morning．By the end of the day，it covered 47 square miles．The fire changed the life in the area，causing hour﹣long traffic jams，and making the people leave their

Something in his tone told me that he was not looking forward to the bee. I could not understand! It sounded like a lot of fun to me.All day, I found myself wishing I was in middle school, so I could take part in the geography bee. During my lunch break I walked up to my social studies teacher’s classroom and asked her if I could take part in the bee for middle school. But she did hesitate (犹豫) a bit because I was too young, just a primary school pupil. I told her that I really loved to learn about our earth, its rivers, mountains, all the human cultures on it. She was still not sure but finally said,“Y es.” I jumped at once!That next morning I was going to be in the school bee as a participant and learn things I was really interested in. I was not nervous one bit, instead just very excited to be doing something I really loved. We had four written rounds —two on the United States and two on the world. I did surprisingly well and placed on the top ten, beating some of the strong seventh and eighth graders.I lost in the oral round the next day, but won my teacher’s attention. I came home and looked up the answers to the questions that I and other students lost on.I placed second in my school the following year, but more importantly, I realized that I really loved geography and enjoyed the time I spent learning it. I may have lost that first bee, but I won the world; a love for that world; love to explore that world — one country, one mountain, one river, one landform at a time; and that is certainly the biggest win for me truly!44. The underlined word "participant" in the passage means "___________".A. 初学者B. 监考官C. 联络人D. 参与者45. From the passage, we know that Jimmy was probably a(n) ____________.A. primary school childB. geography teacherC. eighth grade studentD. middle school worker46. What did Jimmy think of his first geography bee?A. He was very sorry to lose the geography bee.B. It made him fall in love with geography from then on.C. He placed second in the speaking round the next day.D. It made him get to know it was hard to learn geography well.CCollege students often hear about the “freshman fifteen”. What does it mean? You may wonder.It means the fifteen pounds, or about seven kilograms students might gain(获得) in their first year of college.Many young men and women put on extra weight when they start college. Someschools have studied it. Cornell University in Ithaca, New York, has found that freshmen gain an average of four pounds during their first twelve weeks. That is almost two kilograms. If weight gain continues at this rate(比率), how long will they put on fifteen pounds? The answer is forty-five weeks, or almost a year.And why do so many freshmen gain weight? The answers listed by experts are not so surprising. The freshmen gain weight because it’s the first time for college kids to enjoy complete control over their own lives. They may choose to eat and drink whatever they want, whenever they want. For example, college students often eat foods high in fat. After all, there are no parents around to say no to junk food. Students may also miss meals. They could be in class or studying or just … busy. Also, freshmen often use food to relax their mind, they will overeat when they have food as they have college pressures to deal with.This may be short-lived (短暂的), but the weight gain should not be overlooked(忽视). Remember: It requires more effort to lose those pounds than to simply not gain them in the beginning. Or even worse, they may carry the extra weight around for years.36. What does the “freshman fifteen” mean?A. The first fifteen days at college.B. The freedom first-year college students enjoy.C. The fifteen pounds first-year college students gain.D. The fifteen pounds first-year college students lose.37. Some freshmen often overeat to ________________.A. give themselves more energyB. gain extra weightC. taste junk foodD. take pressures off their mind38. How many reasons are given in Paragraph 4 for students’ weight gain?A. One.B. Two.C. Four.D. Five.39. What does the pronoun “This” in the last paragraph refer to?A. Weight.B. Freshman fifteen.C. Pressure.D. Eating.40. We can infer from the last paragraph that ______.A. “freshman fifteen” may have long-term effect on college studentsB. weight gain is nothing serious for freshmenC. “freshman fifteen” is not a common problemD. “freshman fifteen” is a problem hard to prevent五、阅读与表达（一空一词。
