Crowds lined the streets, cheering and waving. Fry rode west for 90 miles at full speed. He then passed a leather bag full of letters to another rider. Eventually a chain of riders carried the letters across nearly 2,000 miles of wilderness, and the Pony Express was born.Between California and the rest of the U.S. lay a vast wilderness. Mail service was slow and often delayed. As war among the states seemed likely, people wanted news more quickly.In December 1859, William Russell, owner of a transport company, decided to meet that need. He and partners William Waddell and Alexander Majors worked constantly for months. They selected a route from St. Joseph, Missouri, to Sacramento, California. Then they purchased 400 horses, hired workers and set up relay stations （导站）every 10 to 15 miles. Riders would change horses at these stations, and every 90 to 120 miles a new rider would take over.Shortly before Jonny Fry set out, another Pony Express rider set off from Sacramento for St. Joseph. These first deliveries reached their destinations in close to the 10 days Russell had promised.But the route was far from safe. On April 18, 1860, a rider’s horse stumbled （绊倒）and fell on the rider, killing him. Riders faced rivers, mountains, extreme temperatures-and very unfriendly natives.In May 1860,tensions between the settlers and Native Americans turned into fighting. Native Americans attacked several Pony Express stations, forcing some of them to close temporarily.Despite the risks, the Pony Express lost only one delivery during its one and a half years in operation. And when Abraham Lincoln was elected president, the Pony Express carried the news to California in only five days. It also spread news of the beginning of America's Civil War.The Pony Express service ended in October 1861 after a telegraph line across the U.S. was completed.Yet the riders' courage and accomplishments still hold a place in legend（传奇）.56. The passage is mainly about the _____ of the Pony Express.A. functionB.influenceC. historyD. operation57. To _____, William Russell decided to set up the Pony Express.A. shorten the time of sending mailB. deliver mail farther and more safelyC. meet people's different needsD. help people keep in contact in war58. What might Russell have promised about the first deliveries?A. To make the destinations closer.B. To make the deliveries within 10 days.C. To ensure the deliveries with two riders.D. To complete the deliveries before the war.59. What can be learned from the passage?A. The Pony Express had an insignificant position in the development of mail service.B. The fighting between the settlers and Native Americans ended the Pony Express.C. The Pony Express became successful as a result of the dangers on the route.D. The Pony Express not only delivered mail but spread news as well.（B）Please Choose Cloud ServicesFinding the Cloud service can be difficult as there are so many available.Consumers need to consider and compare each service’s features, storage possibilities, free space and best price. You may be unsure, or you do not know where to begin. Trying every Cloud service would take a lot of time and work. But, the website might help.CloudDrop-box Google-Drive One-DriveBoxBest For LightweightUsersTeams AndCollaborationDevotedWindowsUsersEnterpriseSolutionsFree Storage Space2GB15GB15GB10GBCheapest PremiumOption1TB100GB100GB100GB One valuable feature is the protection of digital files, including photos, videos, documents, music and more. If the worst happens and your computer crashes, or gets lost or damaged, your files can still be found in the Cloud.Cloud services let you access your files from almost anywhere. No need to worry about a file stored on your computer when you are away from your desk. If you have an Internet connection, you can open your files from any computer, or from a phone, when they are stored using a Cloud service.Using a Cloud service makes sharing files easier. If you send documents to a group using emails, you may then wonder which version everyone is working with. When sharing files using a Cloud service, everyone will see the same document and the latest version.The first thing to consider is the amount of storage space you need. Check how much space you are currently using on your computer and mobile devices. If your computer or phone is filled with photos and you have little free space, you may want to move your photos to the Cloud. Some Cloud services are free. But, if you need a lot of space, you will probably need one that costs money.Even if everyone you have ever met is a Windows user, you still probably want a Cloud service that works with many platforms. You might become friends with anAndroid user or start a job with a company that computes on Apple!60. Which of the following is true according to the passage?A. Google-Drive users can obtain 100GB for free.B. Most Cloud services can send files to both the Cloud and the local computer.C. It's hard to transfer your file when you turn on the computer if it is stored in the Cloud.D. Never worry about finding your files in the Clouds if the computer system crashes.61. What will you have to do if you need more space to store more files in the Cloud?A. To use your own Cloud services.B. To share Cloud space with others.C. To spend money buying space.D. To buy the latest version of the service.62. How can consumers find the Cloud service that suits them best?A. By learning more information about the space occupied by files.B. By comparing Cloud’s function, storage, available space and prices.C. By sending files to a group of people via e-mail inquiring about the Cloud service.D.By making friends with Android users who use Apple computers.（C）Every day, Lucy Dong and her best friend Amy Zhu wake at 7 a.m. -- 7.10 a.m.If they are lucky---rush through their breakfast of steamed buns and noodles, and head off to what may be the best schooling system in the world.The 10-year-olds, who are natives of Shanghai, study in 35-minute bursts from around 8 a.m. to 4 p.m., with a small break for lunch -- and a class meeting --- sandwiched in the middle.Outside school hours, the girls' lives are lots of extra-curricular activities: English class, flute class, drumming class, handwriting class, calligraphy class, Taekwondo training, modelling lessons and choir practice.Shanghai was crowned --- for the second time …the champion of the Programme for International Student Assessment （PISA., which compares the maths, reading and science skills of some 510,000 secondary school students around the world）.Some experts question the value of comparing cities and countries. Others point out that Shanghais relatively well-funded schools and well-paid teachers are not representative of the Chinese education system as a whole.Even so, the latest results are likely to see more and more educators flock east in search of the mega-city's magic formula.Professor Kong Lingshuai of the College of Education at Shanghai Normal University has studied the city'sPISA successes. He says that the secret is a mix of "traditional elements and modern elements". The former is related to the high expectations of "tiger" parents, and a belief in Chinese children from a young age that effort is crucial to gaining a good education. The "modern elements" include Shanghai's willingness to constantly adapt its curriculum and teaching practices; its focus on improving under-achieving schools by pairing them with those that excel; its openness to foreign ideas; and the introduction of performance-related pay.An obsession with training has also been the key, says Prof. Kong. As of last year, new teachers have to undergo a standardized, one-year training course before starting in the classroom. Once qualified, they are required to complete at least 240 hours' training in their first five years, including online learning, paper reading, essay writing and so on. Teachers are also encouraged to attend each other's classes to promote a culture of "idea sharing, exchanging and positive competition".Outsiders often dismiss China's education system as a pressure-cooker-style craze of exams that places too much emphasis on rote-learning and does little to stimulate creativity. But in Shanghai at least, that may be starting to change. Authorities are attempting to move away from testing that relies too heavily on memorizing facts and figures, and some schools are also giving students more time to play, rather than just study.63. The author mentions Lucy Dong and Amy Zhu in the first 3 paragraphs to ________.A. praise the industriousness of these two girlsB. give readers the whole picture of Chinese educationC. illustrate what education in Shanghai looks likeD. criticize the burden the education brings on them64. Why do some experts challenge the result that Shanghai ranked 1st in PISA test?A. Because the value of PISA, which only tests 510,000 students globally, is cast doubt on.B.Because Shanghai has drawn more attention and resources from the central government.C. Because only maths, reading and science skills are compared in PISA test, which is not enough.D. Because Shanghai has a better system of financial support for schools as well as for teachers.65. Which of the following is closest in meaning to "dismiss"in the last paragraph?A. To consider something inferior.B. To stop thinking about something.C. To give the credit for something.D. To claim the features of something.66. Which of the following statements is true according to the passage?A. Strict parents contribute little to the academic success of their children.B. Students have more free time to spend on their interest across China.C. Many education researchers are getting to Shanghai to study the phenomenon.D. Under-achieving schools are usually substituted by those academically superior schools.（D）A. Holidays are when my family gathers and has a good time together,B. School education has civilized me with a mind for peace and calm.C. My parents raised me with a lot of beliefs that have had an effect on who I am today.D. Summer is the time when we always organize some special events as a big family.E. However, I know that it is important to follow the golden rule and to treat others with dignity and respect.F. We take care of each other and try to treat others with respect.What Makes Me "Me"?My culture comes from where I am from and where I was raised. I am an American.I was born and raised in Alaska. My ethnic background is German, English, and Scottish. Culture is all about family. It is a family's belief systems, the cultural traditions that are celebrated, and the special holidays and events that occur in the year._____67_____These are the beliefs that don't just belong to my culture, but they come straight from the values of my family. I believe that women are more intelligent than men because my mother is a strong woman. I was raised to believe that through hard work I could become successful and have a good life. I strive to do this every day and to be good at my life and my jobs. I'm not really religious. _____ 68_____ I believe that if you are a good person to others you will be rewarded for it in many ways.There are a lot of cultural traditions that my family has. Some are from my cultural background and some are from the place where I was raised. I raise my son to have manners and to be well behaved. I raise him to know that hard work is important and that he is expected to put his best effort into things._____69_____We gather every summer in Haines so that all the cousins can grow up together. Birthdays were always important events while growing up. My mom was excited to celebrate every holiday. Trick or treating on Halloween, hiding baskets on Easter, passing out cards to classmates on Valentine's Day, wearing green on St. Patrick's Day, and of course loads of presents under the tree on Christmas morning. My parents always made holidays a big deal so now my son also gets to be excited for them every year.My culture makes me a person that celebrates life. My family has a lot of good friends and we are usually a good part of the community. ______70____ We like to go outdoors and have adventures. My belief systems, cultural traditions, and special events have made me a happy person who is fun to be around and who can have a positive impact on others.Keys31-35 JAFKE36-40 GCBHICloze41-45 ACDCB46-50 ADBDA 51-55 ACBDAReadingA:56-59 CABD B:60-62 DCB C:63-66 CDAC D:67-70 CEAF。

（4分）大概是太过于念念不忘了，连阿长也来问《山海经》是怎么一回事。

这是我向来没有和她说过的，我知道她并非学者，说了也无益；但既然来问，也就都对她说了。

过了十多天，或者一个月罢，我还很记得，是她告假回家以后的四五天，她穿着新的蓝布衫回来了，一见面．就将一包书递给我，高兴地说道：“哥儿，有画儿的‘三哼经’，我给你买来了!”我似乎遇着了一个霹雳，全体都震悚起来；赶紧去接过来。

打开纸包，是四本小小的书，略略一翻，人面的兽，九头的蛇，……果然都在内。

这又使我发生新的敬意了，别人不肯做，或不能做的事，她却能够做成功。

她确有伟大的神力。

谋害隐鼠的怨恨，从此完全消灭了。
