A Finally, I got a part – time job working at the local coffee shop. I had figured that the job would be easy. However, the actual situation was not what I had expected. The customers were hard to please. There was always too much sugar, too little ice, or not enough skimmed milk. However, I kept at it. One rainly day, Hank, one of my regular customers, came in looking sad and defeated. I asked what the problem was and if we could help, but Hank wouldn’t tell me any details. He just said he felt like going to bed, pulling the sheets up over his head, and staying there for a few days. I knew exactly how he felt. “It’s on me,” I told h im. “Have a nice day.” He smiled and thanked me before turning around and heading back out into the rain. The next day was a horrible one. The rain kept pouring down and I spent my afternoon hanging out the window, handing people their orders. What’s worse, no one felt like tipping (给小费) that day. However, around 7:00 pm, Hank drove up to the window. Instead of ordering anything, he handed me a single pink rose and a little note. He said that few people take the time to care about others nowadays and he was glad there were still people like me in the world. I was speechless and very touched; I hadn’t thought that I had done anything incredible. The note read: Christine, Thanks for being so sweet, kind and thoughtful yesterday. I was sincerely touched by you. It is so nice to meet someone that’s nice, warm, sensitive and unselfish. Please don’t change your ways because I truly believe that you will excel. Have a great day! Hank Later, I did come across more complaining customers. But anytime I felt sad or just sick of coffee, I thought of Hank and his kindness. Then I would smile, hold my head up high, clear my throat and ask politely, “How can I help you?” 56.How did the author feel after he began to work at the coffee shop? A.Excited. B.Confused. C.Disappointed. D.Satisfied. 57.What happened to the regular customer of the author? A.He was very sick and had to stay in bed for some days. B.He was not satisfied with the coffee served to him. C.He was anxious to stay at home for a long time. D.He was not feeling himself for some reasons. 58.What does the underlined word “skeptically” probably mean in the passage? A.questioningly B.hopefully C. anxiously D.excitedly . 59.It was Hank who helped the author realize the importance of A.patience in one’s work B.being kind to regular customers C.taking time to care about others 60.What is the best title of the passage? A.A Warm – hearted M an C.My Part – time Job B.Coffee Shop Kindness D.A Horrible Raining Day B When asked to point out one or two things that are most important to themselves, many people put friends ahead of homes, jobs, clothes and cars. A true friendship carries a long history of experience that determines who we are and keeps us connected. It is a treasure we should protect. Unfortunately, the better friends you are, the more probably you’ll have disagreements. And the result can be what you don't want -- an end to the relationship. D.sticking to one’s own career The good news is that most troubled friendships can be mended. First, don't let your pride get in your way. Most of us can forgive each other when differences are brought out in the open. Second, apologize when you're wrong -- even if you've been wronged. Over the course of a friendship, even the best people make mistakes. Sometimes, it may be best if the wronged person takes the lead and apologizes. When you apologize, give your friend a chance to admit that he has been wrong. Third, see things from your friend's point of view. And finally, accept that friendships change as our needs and lifestyles change. Making friends can sometimes seem easy. The hard part is keeping the connections strong during the natural ups and downs that have an effect on all relationships. My suggestion

consider friendship an honor and a gift, and worth the effort to treasure and nurture. 61. What would be the best title for the text? A. Easy Ways to Make Friends B. Ups and Downs in Friendship C. How to Mend a Troubled Friendship D. How to Take the Lead in Making Friends 62. The "wronged person" underlined in the text refers to a person A. who has been mistaken for another B. who has been blamed unfairly C. who has treated friends badly D. who has admitted his mistakes 63. According to the text a friendship can last long only if ________. A. we have much in common C. we treat our disagreements wisely D. we have known one another for long 64. Which of the following statements is wrong according to the passage? A. Many people think friends are more important than homes and jobs. B. Good friends are more likely to have disagreements. C. It is worthwhile to cherish and strengthen true friendship. D. Good friends shouldn't have any disagreements, otherwise their friendship will end in fai lure. 65. What should we do if we follow the author's second sugges tion? A. Stick to our own points of view. C. Make an apology first. B. Avoid making mistakes. D. Change our lifestyles. C Nowadays everybody seems to think that they know English. Many people speak it but few speak it really well. Practice is necessary in speaking English well. B. we know our friends’ mistakes Reading is also one of the things that will help you to speak English better. Read whenever you can and whatever you like! Read papers and Internet sites that you like in English every day. Then, you will see that the number of known words is increasing and you are able to speak with more skills. Then you will have made the foundations and a good basis of English. It is not good to stop and get stuck there. Going to England or an English – speaking country is a good choice, but many people cannot afford it. If you cannot go, reading and speaking with your friends will also help you to practice your English. However, I think it is very good to visit some English – speaking country to see and test you knowledge in everyday life. You will understand the everyday usag e of the language in its natural environment. There your level of English is going to improve even faster. You ability to speak English is better. Nothing can match the excitement and happiness when a native speaker tells you that your English is very good! Finally, in order to speak English well, you must be persistent and do it every day. It is like playing the piano. Pianists play it every day and so should you. Include English in your life and you will see where it is going. Practice, practice! Read, write and improve your language skills and you are on you way when you will be able to speak it with more and more confidence! 66. Which of the following would be the best title for the passage? A. How to Improve Your Language Sk ills B. How to Speak English Well C. Speaking English D. Practice, Practice! 67.

A. we should play the piano every day 21 世纪教育网 B. speaking English is fun and entertaining C. we should practice English every day to improve our speaking skills D. if we’ve learned to read and write, we’ll certainly be able to speak 70. According to the passage, what may make the author excited? A. Reading papers and Internet sites. B. Having a good basis of English. C. Going to an English – speaking country. D. A native speaker’s praise. D I don’t think there is anything wrong with your blood. The key to your problem is that long nap after dinner. If you didn’t sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn’t nap after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day. You should get out of the habit of sleeping during the early evening. Right after your evening meal, engage in some sort of physical activity-a sport such as bowling, perhaps. Or get together with friends for an evening of cards and conversation. Then go to bed at your usual time or a little earlier, and you should be able to get a good night’s rest without taking a pill. If you can get into the habit of spending your evenings this way, I am sure you will feel less tired during the day. At first it may be hard for you to go to sleep without taking a pill. If so, get up and watch television or do some jobs around your house until you feel sleepy. If you fall asleep and then wake up a few hours later, get up but do not take a sleeping pill. Read a while or listen to the radio, and make yourself a few hours’ sleep that night, you will feel better in the morning than you usually feel after taking a pill. The next night you will be ready to sleep at an earlier hour. The most important thing is to avoid taking that nap right after dinner and avoid taking pills. 71. According to the writer, it is difficult for you to go to sleep because ________ . A. you get the habit of staying up late B. you haven’t taken sleeping pills C. you sleep for hours after dinner sleeping during the evening? A. Go to bed earlier than usual. C. Stay with friends after dinner. A. you stay up too late C. you take sleeping pills B. Talk with friends after dinner. D. Do some physical labor. D. you fail to do some exercises 72. Which of the following is NOT TRUE if you want to get out of the habit of 73. You feel tired all day probably because ________________ . B. you get up too early in the morning D. you wake up too frequently at night 74. Which of the following is TRUE according to the passage? A.You mustn’t take sleeping pills in order to get a good night’s sleep. B. You should stay up if you want to sleep effectively. C. Food is necessary at night if you fail to go to sleep. D. It is very important to get out of the habit of taking a nap after dinner. 75. We may infer that the author is most probably a __________________ . A. doctor B. reporter C. scientist D. professor 第 III 卷(读写能力测试,共三节,满分 45 分) 第一节:完成句子(共 10 小题;每空 1 分,满分 10 分) 根据横线上的首字母提示或括号内的汉语提示完成句子。
