There are various aspects that go into making a successful school, and success can be measured in various ways ．Often, the teachers are praised for a school’s success and blamed for its failure ．Yet, in order for a school to be effective, it must be a place where teaching and learning can easily take place, and that requires the hard work of more than just educators ．Students must take learning into their own hands and feel as if what they are doing is as important as it actually is ．This can only be done with the cooperation of every adult that is involved in the students’ life ．Some of these individuals often go unnoticed, yet the role they play in the students’ lives is immeasurable ．In the school, administrative assistants greet students at the start of the day and answer a large quantity of questions ．When an assistant remembers a student’s name or even something special about that student, it communicates to him that he is cared for ．The assistant can also give that extra encouragement for a student to make better choices, especially when they are试卷第2页，共14页visiting the principal’s office ．Meanwhile, though cafeteria workers have a short space of time to interact with students, they can make a big difference as well ．Beyond meeting nutritional needs, cafeteria workers may also on occasion meet the emotional needs of the students they serve ．Students benefit from positive interaction with adults, and cafeteria workers may give that extra bit of encouragement that a child needs ．Custodians （管理员）are usually underappreciated for what they offer to schools ．They have to be knowledgeable about everything from cleaning to fixing the most intricate （复杂的）tools ．They get to school early in the morning before teachers arrive and lock up late at night after the last student has left from the after-school event ．They also make sure teachers are equipped with the necessary items and prepare the rooms so that they are ready for learning ．A great custodian also gives that kind word or extra smile to that student who needs it most ． 1、The purpose of the passage is to _______． A ．emphasize the role teachers play in a schoolB ．highlight the contributions of other staff at school besides teachers ．C ．tell us who make the greatest contributions to a schoolD ．explain what contributes to the success of a student2、If an assistant remembers a student’s name, the student will feel that _________． A ．he is paid particular attention to B ．he is specialC ．he has done something wrongD ．he has made progress in study3、Which of the following is TRUE about cafeteria workers? A ．It’s enough for them to cook for the students ． B ．It’s hard for them to interact with the students ． C ．They have the most interaction with students at school ． D ．They can also meet the emotional needs of the students ．4、How does the author feel about the staff mentioned in the text? A ．Disappointed ． B ．Dissatisfied ． C ．Appreciative ． D ．Doubtful ．阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

AThe most frightening words in the English language are, “Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I’m sorry, I can’t sell you a ticket. Our computer is down.”“If your computer is down, just write me out a ticket.”“I can’t write you out a ticket. The computer is the only one allowed to do so.”I noticed every passenger was just standing there drinking coffee and staring at the black screen. Then I looked down on the computer and asked her, “What do all you people do?”“We give the computer the information about your trip, and then it tells us whether you can fly with us or not.”“So when it goes down, you go down with it.”“That’s good, sir.”“How long will the computer be down? I wanted to know.”“I have no idea. Sometimes it’s down for 10 minutes, sometimes for two hours. There’s no way we can find out without asking the computer, and since it’s down it won’t answer us.”After the girl told me they had no backup computer, I said. “Let’s forget the computer—What about your planes? They are still flying, aren’t they?”“I couldn’t tell without asking the computer.”“Maybe I could, just go to the gate and ask the pilot if he is flying to Washington,” I suggested.“I wouldn’t know what gate to send you to. Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”“Is there any other airline flying to Washington within the next few hours?”“I wouldn’t know,” she said, pointing at the dark screen. “Only ‘IT’ knows. It can’t tell me.” By this time there were quite a few people standing in lines. The words soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.1．Where do you often hear the frightening words “Our computer is down”?A．at the airport. B．At the gate.C．On business D．In the ticket office2．What could the girl in the ticket office do without asking the computer?A．She could do nothing.B．She could write out a ticket.C．She could still sell a ticket.D．She could answer passengers’ questions.3．What does the underlined word “down” in Paragraph 1 mean?A．White B．Broken C．Black D．Dark4．We can learn from the last paragraph that .A．a modern computer won’t be downB．computers can take the place of humanC．there will be great changes in computersD．sometimes a computer may bring suffering to peopleBThe average British 22 year-old has more than 1,000 online friends on sites like Facebook, compared to those in their fifties who have fewer than 20, according to a new study.The “Facebook generation gap” has been highlighted in a new piece of research which shows that the average 22 year-old claims to have 1,000 or more friends on sites like Facebook.People in their twenties have more than 50 times as many digital friends as those who areover 50 years old, despite the popularity of sites like Facebook with the older generations, says a study conducted by consumer research group Intersperience.The news comes during the same week Facebook's second-in command, Sheryl Sandberg, is visiting the UK to deliver a speech at the London School of Economics.Facebook's chief operating officer is going to speak about how the social web has transformed people's friendships and relationships.The survey found that there was a clear link between people's age and the number of online friends they have．The researchers found that those aged 13 to 16, have an average of 450 friends on social networks, with girls having slightly more friends that boys．People in their thirties tend to have between 100 and 200 friends, while those in their forties have between 50 and 100.However, those using sites such as Facebook over the age of 50, tended to have 20 or less friends．The oldest person surveyed was 70 years old.Paul Hudson, Intersperience's chief executive, said: "Our research underlines fundamental （根本的）changes taking place in British society as a result of finally entering the digital age．Half of the UK population are on Facebook now．In a social media context, a 'friend' means something different to a 20 year old than to a 50 year old."He added: “Social networking activity is just one e xample of how different groups are adapting to the digital age at different paces．In this case, age is the determining factor - however in other instances it is not.”5．Which is the determining factor in social networking activity?A．Gender B．Age C．Relationship D．Pace 6．What can we learn from the survey?A．The older a person is, the less online friends he may haveB．Girls have remarkably more friends than boysC．People in their thirties tend to have between 50 and 100 friendsD．The link between peop le’s age and the number of online friends they have is not clear 7．According to the passage, the following statements are True except .A．The oldest people surveyed is 70B．Paul Hudson will deliver a speech at the London School of EconomicsC．Different groups are adapting to the digital age at different pacesD．Facebook is popular in UK now8．What’s the main idea of the passage?A．Social networking activityB．The digital ageC．“Facebook generation gap”—Facebook generation has more than 1,000 friendsD．Changes taking place in British societyCYou may have noticed something different when you ate at your favorite restaurant. Or perhaps you picked up on it while looking through your social media apps （社交媒体软件） . You guessed it ---we’re becoming a foodie （吃货）culture.For some, that means photographing every dish, but others are taking it one step further. Sophia Hampton, a senior at Staples High School in US, chooses to make her own food. She has been published in Future Chefs, a cookbook of recipes （食谱）by teens.Hampton’s best advice for those who want to be foodies is to get in the kitchen.“Start cooking,” she said. “There are so many resources online, like recipes and articles about food. Go to your local farmers’ market and start cooking with them.Besides blogs and online resources, there are also hands-on cooking classes for students. The Chopping Block, a Chicago cooking school, offers many different classes for teens, including courses on chocolate and French food.By attending cooking classes, surfing online and going to restaurants, you can find endless recipes. But sometimes becoming a real foodie means being behind a camera. As our food-loving culture becomes more popular and teen-friendly, social media apps like Facebook, have become major players in food culture.“Getting involved in foodie culture is as easy as having a camera and a social media app,” one foodie said. “I always go to streets and farmers’ markets to take beautiful pictures of food. Wherever food prices are expensive, the photos are free.”9．What does Hampton advise those who want to be foodies to do?A．Post their recipes online. B．Cook food by themselves.C．Eat at their favorite restaurant. D．Take photos of every dish they eat. 10．Where can students find new recipes, according to the article?①cooking classes ②online resources ③new restaurant ④public librariesA．①②③B．①③④C．②③④D．①②④11．What has made foodie culture more popular, according to the article?A．People’s growing inter est in traditional culture.B．The convenience of getting different food.C．The use of cameras and social media.D．The drop in food prices.DAfter I made it to the city center, I started to feel it might be easy for a foreigner to deal with the great size of Beijing. With growing confidence, I decided to take the subway to the hotel, not realizing that the network didn’t go that far. Impressed with the cleanliness of the station, I bought a ticket and boarded the first train that came along.After a few minutes I asked in English of course a young man seated next to me where I should get off closest to the Friendship Hotel. Wearing a smart business suit and tie, he would surely speak English, wouldn’t he? Unfortunately, he couldn’t understand me but seemed v ery friendly. I showed him the room card with all the information of the Friendship Hotel in Chinese characters. He looked at it, and then his eyes moved quickly to the carriage （车厢）subway map. Next, he raised three fingers of his right hand.In Australia, raising fingers at someone is not usually nice, but this man wasn’t smiling. At the next station he showed me two fingers. Now in Australia, that’s really rude, but I got the message. When we stopped at the third station, he didn’t just point to the door, but got up, took me out of the train, and led me to the top of the stairs, and out onto the street. Then he stopped a taxi and told the driver where to take me.All this came from a man who couldn’t speak my language, and I couldn’t speak his. I was now speechless, especially when he refused my offer of money. I felt a little embarrassed having even thought he would accept a tip.This experience made it clear I had to learn some Chinese quickly or my adventures might start turning into bad luck.12．The author decided to take the subway because ________.A．he lived near the city centerB．the network covered most of the stopsC．he believed in his ability to deal with the tripD．he had a good impression of its cleanliness13．Having been shown the room card, the young man_________.A．understood the author well B．still remained puzzledC．answered the author directly D．pointed at the subway map 14．Which of the following can’t be used to describe the young man?A．helpful B．rude C．warmhearted D．caring 15．The author’s purpose of writing this passage is mainly to ________.A．prove the importance of being carefulB．appreciate the kindness of the young manC．complain some cultural misunderstandingD．describe one of his adventurous experiences第二节（共5小题；每小题2分，满分10分）根据短文内容，从选项中选出能填入空白处的最佳选项。
