Washington, D. C. has the National Gallery of Art；Paris has the Louvre；London has the British Museum. Florida International University(FIU) in Miami also shows art for people to see. And it does so without a building，or even a wall for its drawings and paintings. FlU has opened what it says is the first computer art museum in the United States. You dont have to visit the university to see the art. You just need a computer linked to a telephone. You can call the telephone number of a university computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically(电子地) by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings. Robert Shostak is the director of the new computer museum. He says he started the museum because computer artists had no place to show their works. A computer artist could only record his pictures electronically and send the records, or floppy disks(软盘), to others to see on their computers. He could also put his pictures on paper. But to print good pictures on paper, the computer artist needed an expensive laser(激光) printer. Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Many of the pictures in the museum are made by students. Mr. Shostak said the FIU Museum will make computer art more fun for computer artists because more people can see it. He says artists enjoy their works much more if they have an_audience. And the great number of home computers in America could mean a huge audience for the electronic museum.【文章大意】本文是一篇说明文。文章主要介绍了如何利用电脑欣赏艺术作品。5. The main purpose of this text is to give information about _.Afamous museums throughout the worldBa computer art museum in Miami, the USA.Cart exhibitions in Florida International UniversityDthe latest development in computer art解析：B写作目的题。作者首先在文章开头介绍了世界上著名的博物馆，接着引出迈阿密州的Florida International University的电子美术馆，接下来详细地介绍了该电子美术馆，因此B项为最佳答案。6. To see the art in the FIU Museum, your special needs include _.Afloppy disksBa computer and a printerCpictures and drawings on paperDa computer connected to the museum by telephone line解析：D细节理解题。根据第三段的内容可知答案。7. The museum was started because _.ARobert Shostak wanted to do something for computer scientistsBRobert Shostak wanted to help computer artistsCart students needed a place to show their worksDcomputer scientists wanted to do something about art解析：B推理判断题。由第四段中He says he started the museum because computer artists had no place to show their works.可知，B项为最佳答案。C项有较大干扰性，从文章最后一段看似乎这一选项正确，然而从第三段看，这家电子美术馆是面对所有的艺术家，而并非只面对艺术学生。8. The underlined words “an audience” in the last paragraph refer to _.Aart studentsBowners of computersCexhibits in the museumDthose who can enjoy art解析：D词义猜测题。根据句中的“artists enjoy their works much more.”可推断此处的观众是指能欣赏艺术品的观众，故可推知选D项。C When Ricochet was just a young pup, her owner Judy Fridono hoped the dog might one day become a service dog and help people. But Ricochet had other plans, at least for the first part. She failed at service dog training, but she went on to help millions of people around the world learn how to trust, how to love, and how to surf (冲浪) According to Fridono, the dog seemed naturally suited to life as a service dog. She was great with people, especially kids, and she had plenty of energy. But birds were her weakness. She just couldnt seem to stop running after them. And thats not a good quality for a service dog that needs to focus on the person shes helping. Fridono said at the beginning she was disappointed when Ricochet didnt succeed at service dog school. But it wasnt long before the pup let her true skills shine through. At just 8 weeks old, Ricochet climbed on to a board that had been left in a childrens pool, showing her special talent for balance. Soon, Ricochet was making headlines as the beachloving dog who could hang ten on a surfboard. But she wasnt finished showing off her special talents yet. “One day at the beach, she jumped on a surfboard with a 14yearold boy who had spinal cord (脊髓) injuries，” Fridono said. “It was at that moment that her life purpose to surf with people who are disabled was realized. Shes just such an inspiration to everyoneshes got such a strong connection to people, and we see such improvements in the people who she surfs with.” Ricochet now surfs daily with children and adults with special needs. She specializes in helping military veterans (退伍军人) with PTSD (创伤后应激障碍) and children with autism (自闭症) by connecting with them in ways that no one else can.【文章大意】本文是记叙文。文章主要讲述了一只服务犬Ricochet帮助有特殊需求的人的故事。9. What do we know about Ricochet?AShe was taught how to surf.BShe has been helpful for many people.CShe saved thousands of peoples lives.DShe learnt special skills at service dog school.解析：B细节理解题。由第一段中的she went on to help millions of people around the world learn how to trust, how to love, and how to surf可知，Ricochet在服务犬学校的培训并不成功，但是她依然帮助了很多人。10. What was Ricochets greatest shortcoming?AImpatience. BGreat pride.CNot being brave. DLack of concentration.解析：D推理判断题。由第二段中的But birds were her weakness . And thats not a good quality for a service dog that needs to focus on the person shes helping可知，Ricochet似乎不可能停止追逐鸟儿，而做服务犬要求她集中注意力于她正帮助的人身上。11. What may have amazed Fridono?ARicochets rapid progress.BRicochets extraordinary talents.CRicochets widespread popularity.DRicochets dropping out of school.解析：B推理判断题。由第三、四段的描述可知，Ricochet很小就展示出她非凡的天赋和才能。12. What can we infer from the text?ARicochet once had a spinal cord injury.BFridono made Ricochets dream come true.CFridono helped Ricochet develop her skills and talents.DRicochet has a unique connection with special needs people.解析：D推理判断题。由倒数第二段中的shes got such a strong connection to people, and we see such improvements in the people who she surfs with和最后一段中的She specializes in helping. by connecting with them in ways that no one else can可知，Ricochet能与有特殊需求的人建立特别的关系。.七选五 Like other continents, Africa is also home to rich cultures with clear rules of etiquette (礼节), In all African cultures, it is unacceptable to pass another person without giving a greeting. _1_ For example, in northern Uganda, the younger person greets the older person first as a sign of respect, while in western Uganda, the older person does so first. When greeting, the two ask about each others health, family, etc. In Africa, older people are always respected. For example, it is unacceptable to interrupt older people when they are talking, or to walk away before they allow one to go. _2_ For example, fetch things from the shop or the market for them. _3_ In northern Uganda, for example, it is impolite to have whatever you are eating run down your fingers towards your elbow. And in the whole of Uganda, it is the worst form of bad manners to eat while walking because they think food should be honored by sitting down to eat it._4_ Whoever has experienced good fortune will organize a dinner for everyone, in turn, whoever experiences bad fortune will be helped by everyone. _5_ If he is unfortunate one day, he will be sure not to go hungry but to receive something from the lucky hunter.AIn Africa, everybody shares what they have.BHowever, greetings are governed by many rules.CIn addition, children are expected to do something for them.DIts thought that every adult should be responsible for every child.E. Greetings are a means of staying informed about each others lives.F. Though many Africans eat with their fingers, they also have their table manners.G. For example, a hunter who kills a big animal shares the meat with the whole village.【文章大意】本文为说明文，题材为社会文化类。本文主要介绍了一些非洲文化。1解析：B由其后所举的例子可判断此处意为：问候有许多规定。2解析：C由本段第一句可知，本段旨在说明老年人是如何被尊重的。C项“小孩应该帮老人做点事”也是其中一种。3解析：F本空为本段的主旨。由所举的例子可知，本段说明的是table manners。4解析：A根据空后Whoever has experienced good fortune will organize a dinner for everyone. In turn, whoever experiences bad fortune will be helped by everyone描述的是分享之举，故选A项。5解析：G此处举例说明非洲人喜欢分享互助的行为，故选G项。
