I felt horrible as well as16 . What would she do with me? She was almost mad after the17 of her husband.A few minutes later, I heard the truck 18 its engine and move fast. I kept making sounds to show my protest, but failed to make any 19 . Finally she put me down in a 20 place. Maybe she didn’t want me to die from lack of air；she untied the bag.I 21 out and looked up, only to see many strange faces and fingers pointing at me.It turned out that my owner meant to 22 me. I saw my owner on the truck, which was going farther and farther. So I cast my head 23 the direction of the truck. The days we spent together were like a movie playing in front of my eyes as I ran after the truck. I saw my male owner, who suffered from liver cancer, looked at me with his sad eyes. I saw myself 24 my owner everywhere；I saw him lie in his dying bed, she was all 25 .I ran as fast as I could. And the 26 I saw her wave to me, my eyes became wet. I wouldn’t blame her for treating me like this for she was such a(an) 27 lady. She seemed even somewhat 28 at his leaving her alone, trying many ways to 29 the pains of losing him. She 30 his pictures and clothes, and she redecorated the whole house. Now I was the only 31 thing to remind her of him. 32 later, I am pretty sure that she would realize how mad she was to do this…The truck finally stopped when I was almost 33 .

Keeps Kids Out of TroubleKids who live in families that eat dinner together regularly are less likely to be involved inrisky behavior. According to statistics, children who don't eat dinner with their families are 61% more likely to use alcohol, tobacco or illegal drugs. By contrast, children who eat dinner with their families every night of the week are 20% less likely to drink, smoke or use illegal drugs.2.It's Bonding（联系）TimeFamilies who eat dinner together regularly are more likely to have stronger, happier family relationships. As families struggle to find amounts of quality time together, family dinner time provides the opportunity for both. When families hang out together and communicate, they grow strong and healthy.3. Offers StabilityFamilies who eat dinner regularly develop a stronger family identity. Eating together serves to build a family identity. In addition, this family“routine”provides a sense of sta bility（稳定）and security that provides kids with a positive environment where they can grow into healthy adults.25Time for Family UpdatesFamilies who eat dinner together regularly can keep in touch with each other's life. Everyone—kids and parents alike—can keep up-to-date during the family dinner time on what is going on with school,jobs,family life and friends.26Educates Your KidsEating dinner regularly fosters（促进）learning. When families who eat dinner together engage in a variety of conversation topics, learning is encouraged. Kids who are exposed to regular family discussions learn a broader vocabulary.27Healthy for the Whole FamilyKids are likely to receive better nutrition when eating dinner regularly with their families. A simple, but true rule applies: when kids eat with their families, they eat better. Family dinner time means kids are more likely to eat a nutritionally balanced meal, lower in sugar and fat content, than if they prepare or purchase meals on their own.36. What is the text mainly about?A. The benefits of eating meals.B.How to strengthen family ties.C.The importance of family dinner time.D.Ways to keep our kids out of trouble.37. Which of the following statements is NOT TRUE according to the text?A. children learn words mainly from their parents.B.It makes good sense to have dinner with family.C.Family dinner time benefits parents and children.D. Parents can keep in touch with their kids while dining.38.Children can grow stronger and healthier when eating dinner with their familiesbecause .A.they depend on their parents for guidanceB.they develop a strong sense of responsibilityC.school canteens provide balanced mealsD.parents can provide better nutrition for themBSkipping classes violates school rules and a poor attendance record will damage your final mark. But some college students still try every means to escape classes. The number of these rebels may be much bigger than you think. Three students from Anhui Normal University established Itaoke. Com in June. The website quickly attracted 2 000 registered members in three months. On the website, students share their experiences of skipping classes and even post ads to look for someone to stand in for them to attend courses. It’s emb arrassing for universities to seethis shameful behavior discussed.However，it's good for schools and teachers to know via the website the reasons why students skip classes，according to Professor Xiao Haitao from Shenzhen University: Xiao pointed out that some students skip classes because of laziness. Others play truant because the teaching is truly dissatisfactory,“Universities can seek improvements to give a cure to the class-skipping problem，”said Xiao.Chen Yang，21，thinks that he is “forced" to skip some courses because of the poor teaching. The senior，majoring in English at Yangtze University, thinks that he's wasting time in the classroom when the teacher reads the textbook word for word or hands him outdated reading materials. He would rather skip classes to study in the library, watch online videos of Harvard or Yale lectures，or sit in on(旁听）other courses he is interested in. Chen draws a clear line between himself and those who skip classes in order to get more sleep or fool around on campus. He emphasizes：“I skip classes with a clear goal，which is to probe into areas I'm interested in and broaden my horizons.”Li Sicen，President of the National Taiwan University，seems to be on Chen's side. Li claimed that he supported those students who skip classes for good reasons.However，Professor Xiao warns students that Li is not giving permission for students to skip classes. Xiao suggests that Li was just showing his understanding of truancy in a limited number of cases.In Professor Pan Cuiqiong's opinion，students tend to jump to the conclusion that a certain course is boring and useless. "To clear students' misunderstanding，teachers should use materials closely related to students’lives and adapt interactive teaching methods，”said Pan.Besides offering teachers more training，schools also need to give students different optional courses and ensure that they can attend the courses they are interested in，according to Professor Xiao. Many Chinese students have the experience of being kicked out of an optional course because its size is limited. They are then forced to choose courses they dislike and are likely to skip them. We may learn from Sydney University in Australia. There aren't any problems with numbers---if a course is popular then there will be more than one class per week.39. The underlined word “rebels" in Paragraph 1 refers to“A. students who embarrass their universitiesB. students who establish websitesC. students who skip classesD. students who quarrel with their parents40. Chen Yang Skips some courses because＿．A. his school is more student-centeredB. he wants to get more sleepC. he wants to fool around on campusD. the teaching style needs much improvement41. According to the passage，we learn that Professor Xiao＿．A. is giving permission for students to skip classesB. thinks it's embarrassing for the three students to establish ltaoke. comC. thinks the website will help to know why students skip classesD. claimed that he supported those students who skip classes for good reasons42. Which of the following measures is NOT mentioned to stop students skipping classes?A. Teachers should adopt practical materials and flexible teaching methods.B. Schools should offer teachers more training.C. Schools need to ensure that students can attend various courses they are interested in.D. Students should be punished if they skip classes.cWhen I turned four, everything seemed to go wrong. I had asthma(哮喘) and for the most part I was in constant pain. I was in and out of doctors’ offices many times, but they could never find out what was wrong.One night, I had a fever and high blood pressure, and my feet were purple. My parents quickly took me to the emergency room, where they were told I needed my appendix(阑尾) taken out. I lay there that night, getting worse by the minute. At that point, the doctors knew it was more than my appendix.The next day, I was taken to the Children’s Hospital under the care of Dr. Cohen, a kidney(肾) specialist. After two weeks of treatment, I was still not responding. My kidneys were only working 2 percent of the time and if something wasn’t done, I would die.My parents were told their only daughter was dying and without much improvement would be put on a waiting list for a kidney transplant.That night, my dad sat down by my bed and told me I was going to fight harder than I had ever fought before. Suddenly, I reached up and-gathering all the energy I had-I hit him on the nose! He knew then I was not going to give up.The next morning I was given a transplant, and I was put on steroids(透析). Within a couple of days, I started showing steady signs of improvement, but my parents were told, “Kristy will never have as much energy as a normal kid, even if she pulls through. "Well, ten years later, I can proudly say, "Look at me now!" I’m fourteen years old. I play four sports, and I’m a living miracle(奇迹) to my doctors, family and friends. Even if you are only given a 2-percent chance of survival, that’s all you really need.43. The author hit her father on the nose because she wanted to show_____.A. her determination of fighting the sicknessB. she hated her parents because of her weak bodyC. she loved her parents though she was born a sick childD. she hated to be in and out of the hospital44. If Kristy had not been taken to the hospital for the appendix operation,_____.A. her parents wouldn’t have worried about her so muchB. she would have had a kidney transplant immediatelyC. she wouldn’t have been found to have more k idneys than ordinary childrenD. the doctor wouldn’t have probably found out her sick kidneys45. The underlined word "pulls through" in the 6th paragraph probably means “_____”A. takes outB. recoversC. struggles hardD. fails46. From the story, the author tries to tell us that_____.A. at any time, your parents always love you and take care of youB. when you are ill, you must not hate your parents and hit themC. try your best for success, even if you’ve got a small chanceD. everybody will meet with difficulties on the way of his lifetimeDA child-like robot, Wakamaru, developed by Mitsubishi Heavy Industries of Japan and combining the roles of a nurse, companion and security guard, will soon be at the market to look after the growing number of old people with no one to look after them.Cameras fixed under the“eyebrows”of the robot enable it to“see”as it moves around in a house. The images can be sent to the latest mobile phones, which can show the pictures. Wakamaru speaks with either the voice of a boy or a girl. It is also designed to provide companionship, saying hello to its“papa”when he comes home. Based on a vocabulary of around 10,000 words, it is the first household robot which is able to hold simple conversations. It can not only speak, but also understand answers and react accordingly. It will ask“Are you all right?”if its owner doesn’t move for some time. If the answer is no, or there is no answer, it will telephone preset numbers, send images and work as a speakerphone. It can recognize up to 10 faces and be set to tell forgetful people when it is time to take medicine, eat and sleep.However, like most robots, it cannot climb stairs. Mitsubishi developed Wakamaru from robots which have already b een made to go around nuclear power facilities.“Looking at the ageing of society and the falling birth rate we decided that this could work as a business. We want to offer it as a product that helps society,”said the project chief. The developers plan to s ell the robot from April this year at between5,000 and 6,000 pounds.The life expectancy(寿命)of Japanese women has shot up to almost 85, the highest in the world. At the same time, large families are being replaced by nuclear families. This has left many Japanese anxious about their elderly parents. Therefore, the technology has gained nation-wide publicity in Japan.47. The passage is written with the purpose to .A. introduce a new robotB. solve the ageing problemC. tell people the rapid development of technologyD. tell people how to use the robot48. It can be inferred from the passage that .A. the robot can dial any number for helpB. the robot is likely to have a promising marketC. the robot enables the Japanese to live longerD. many elderly Japanese are anxious about their future49. The underlined part“nuclear families”in the last paragraph probably means“”.A. families with nuclear power facilitiesB. small families without a parentC. families with children and old peopleD. families with parents and their children only50. What is the best title for the passage?A. The Latest Development of RobotB. Japanese Robot and the Ageing SocietyC. Large Market of the New RobotD. Japan-made Robot Helps the Old第二节（10分）根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
