请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。（注意：每个空格只填1个单词。） Prepackaged, mass-produced snack foods are hugely popular in grocery stores around the world. Many people are accustomed to choosing snack foods in grocery stores. The first problem with packaged snack foods like cookies, crackers, and other bite-sized options is that they are often loaded with unhealthy materials. The reason for this is fairly easy to understand. Mass-produced foods need to be uniform in color, taste and so on. In order to achieve this uniformity, snack food producers use sugar, salt, and other chemical preservatives (防腐剂) and coloring materials in large amounts. These materials contribute to a rather unhealthy food. In addition to requiring uniformity of taste and appearance, mass-produced snack foods like potato chips and candies need to be shelf stable. Preservatives and complex packaging make products shelf stable, but this stability and non-perish ability (抗腐性) often come at the expense of nutrition. One reason that pre-made snacks are so popular in grocery stores is their prices. Food producers can keep costs down by using established production facilities and processes to quickly produce a huge amount of food. Shoppers are drawn to what they see at low prices. People who are interested in improving the quality of their snacking can use magazines, books, and the Internet to discover a lot of healthy snacking tips and ideas. Even television shows about health and food sometimes talk about healthy snacking alternatives. Some healthy snacks, like fresh fruit, require no preparation at all. Once people are aware of the drawbacks of clearly cheap and easy snack foods, they can start turning to better options. Soon, perhaps, the old and unhealthy snack options will no longer be profitable for food producers.
There is a famous story about British poet Samuel Taylor Coleridge. He was writing a poem when he was interrupted by a knock at the door. This was an age before telephones. Someone was delivering a message. When Coleridge got back to his poem, he had lost his inspiration. His poetic mood had been broken by the knock on his door. His unfinished poem, which could otherwise have been a masterpiece, would now never be more than a fragment. This story tells how unexpected communication can destroy an important thought, which bring us to the cellphone. The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts. We have already entered a golden age of little white lies about our cellphones, and this is by and large（大体上）a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach. The notion of being unreachable is not a new concept—we have “Do Not Disturb” sign on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while? Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees（信徒）, myself usually included, can’t help at times wanting to throw their phone away, or curse the day they were invented. But we don’t and won’t, and there really is no need. All that’s required to take back our private time is a general social recognition that we have the right to it. In other words, we have to develop a healthy contempt(轻视) for the rings of our own phones. A cellphone call deserves no greater priority(优先考虑的事) than a random(随机的) word from the person next to us，though the call on my cellphone may be the one-in-a-million from Steven Spielberg—who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch. 1.What is the point of the anecdote about the poet Coleridge in the first three paragraphs? A．To direct readers’ attention to the main topic. B．To show how important inspiration is to a poet C．To emphasize the disadvantage of not having a cellphone D．To encourage readers to read the works of this poet. 2.What does the writer think about people telling “white lies” about their cellphones? A．It is a way of signaling that you don’t like the caller. B．It is natural to tell lies about small things C．It is basically a good way to protect one’s privacy. D．We should feel guilty when we can’t tell the truth. 3.According to the author, what is the most annoying problem caused by cellphones? A．People get so obsessed(着迷) with the cellphone rings that they fail to notice anything else. B．People feel guilty when they are not able to answer their cellphones. C．Cellphones interrupt people’s private time. D．With cellphones it is no longer possible to be unreachable. 4.What does the last paragraph suggest? A．A person who calls us from afar deserves more of our attention B．Steven Spielberg once called the author to talk about the author’s novel. C．You should always finish your lunch before you answer a call on the cellphone. D．Never let cellphones disturb your life too much.
Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means. Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach. Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth. Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar. Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future. 1.The holly plant has more spines on the lower leaves because most animals________. A．are not tall enough B．like the lower leaves only C．are not clever enough D．can get the lower leaves easily 2.To defend themselves, oak trees use________. A．chemical means B．physical means C．bitter chemicals D．sandy materials 3.How does tobacco protect itself against an attack from a caterpillar? A．Its leaves fight against the attack by physical means. B．Its roots send a messenger to discourage the caterpillar. C．Its roots increase the production of nicotine when it is attacked. D．Its leaves produce poisonous sand to drive the caterpillar away. 4.What would be the best title for this passage? A．Plants and Animals B．How Plants Defend Themselves C．Attacks and Defenses D．How Animals Eat Plant Leaves

SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting "print" on your computer. You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair --- the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it. Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one. However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun? 1.According to the article, in the future, the 3-D printing technology will ___. A．enable people to make better purchases online B．be applied as widely in our daily lives as computers C．change the way we make many products D．shorten the time it takes for people to get what they buy online 2.What was the big event happening in the 3-D printing industry last year? A．The 3-D printing technology was taken out ofthe factory. B．The 3-D printer became more affordable forconsumers. C．The 3-D printer was used for medical treatmentfor the first time. D．3-D printing technology began to be used invarious fields. 3.How is the last paragraph developed? A．By analyzing a cause and an effect. B．By making comparisons. C．By giving examples. D．By presenting research findings. 4.What is the best title of the passage? A．Printing out everything B．Technology in the future C．Online shopping disappearing D．Great demand for 3-D printers
Looking for some inspiration or the “write” kind of ideas for your creative stories? To start with, some writers describe winter by using their five senses or their imagination. Others write on their favorite winter activity. Whatever you choose to write about, working on a winter story can always help to improve your writing skills. Now read the following story and see if it helps get rid of any icy writing block you’ ve been struggling with. A Winter Adventure Beep, beep. Beep-beep: the alarm clock rang. Slowly, I got out of warm bed down onto the wooden floor which the winter had thrown its cold upon. The bitter cold temperature penetrated （穿透）my socks and I hurried to put my feet in shoes. Looking out of the window, I watched the white snow, soft and thick, drop onto rooftops and trees. Half an hour later, finishing the last of my hot chocolate, I prepared to enter the adventure that waited for me outside. I buttoned my jacket and fastened my boots. Hat on, I opened the door and was greeted by the winter coldness. In the depths of winter, the early morning did not have the rush of the rest of the year. Most of my neighbours were put off by the cold, and stayed in bed until the sun had climbed higher into the sky. Unseen by those who remained locked inside their homes, warm in their beds, I enjoyed being alone with the beauty of the wintertime. Those indoors were unable to appreciate the snow-scapes, ice crystals, frost and the crisp（清新的）breeze. For them, the coming of winter meant just the arrival of the cold. Appreciation depends on contrasts. One cannot love the warmth of April if one has not known the freezing cold of winter. Later that year, the heat of the sun on my skin would be all the more wonderful for my memories of that cold morning and others like it. 1.The underlined word “adventure” refers to____________.

C．To inspire readers to take more exercise in winter D．To tell readers how to appreciate the beauty of winter.
Signs can sometimes be seen at the entrance of a house, expressing that a tramp（流浪汉） has passed. This special sign-language is frequently 36 by tramps to inform their 37 whether the host of a certain house is friendly or unfriendly, and to 38 them the trouble of making unnecessary calls. Quite 39 one day, I came across a real tramp. He was such a rare sight these days that I stood some distance away and watched him. He was dressed just as a tramp should be 40 , old worn trousers, and a jacket many sizes too big for him. On his head there was a battered old hat and his boots were so old and worn; they were almost coming into 41 . But the man himself looked cheerful as if he had not been a 42 in the world. He rubbed his nose with his forefinger, 43 a funny turn, laid a small parcel by the front gate, and began 44 a sign made by a former caller. Although the sign was meaningless to me, it must have been 45 , for the tramp’s face lit up with 46 . He entered the front gate confidently and rang the bell. When the door opened, I saw him 47 his hat but couldn’t hear his words. The 48 was very short indeed, for no sooner had he spoken a few words than the door closed fiercely in his face. I felt 49 for him as he walked 50 out of the house, But just as quickly, his face lit up again and he moved quickly towards the gate. There he stopped, looked at the sign, and 51 his head seriously as if he had made a bad mistake. 52 deeply into his pockets, he produced a piece of chalk, rubbed out the 53 sign and made a new one in its place. He stared at it for a moment smiling to himself, then gathered his 54 , pushed back his hat and began walking towards the next house at an unhurried 55 , whistling as he went along. 1.

阅读下面短文，根据所读内容在文后第76至第85小题的空格里填上适当的单词。 注意：每空1个单词。 When it comes to the world of computers, green computing is becoming popular. But what is green computing? The term “green computing” is one that is being used in many different markets and areas all over the world in today’s global technology. However, many computer users aren’t sure what it means. Green computing is actually quite easy to explain and to do—it is basically learning to use computer resources more efficiently to protect the environment as well as saving energy. The main goal is to reduce the use of energy and materials that harm the environment. Green computing started as early as 1992, when the EPA created Energy Star program that improved computing equipment and technologies. Because of this program sleep pattern appeared and many computer users began to adopt this policy to help save energy when they were not using their computers. In October of 2006, Energy Star made the requirements stricter for computers. Because of these new requirements, there are over 20 states that have now set up a special recycling program for old computers to help with green computing. Many of today’s IT systems are beginning to rely on both people and hardware to help push their computer systems toward a more green computing system to help both the company and others. This is a hard balance to achieve, as it has to satisfy users. Many companies are learning the best ways that they call go greener when it comes to their computing and also help their business in the process. While many home computer users may not be quite as familiar with green computing as large firms, this term is starting to become more mainstream all around the world.
Several recent studies have found that being randomly (随机地) assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood (可能性)of conflict. Recent reports found that lodging with a student of a different race may decrease prejudice and force students to engage in more ethnically diverse friendships. An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure. In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove." Researchers also observed problems resulting from pairing interracial students in residences. According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out. An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester. Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said. At Penn, students are not asked to indicate race when applying for housing. "One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration." "I've experienced roommate conflicts between interracial students that have both broken down stereotypes(模式化形象) and strengthened stereotypes," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合)," there were also "jarring cultural resistance." The RA said that these conflicts have also occurred among roommates of the same race. Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained. 1.What can we learn from some recent studies? A．Conflicts between students of different races are unavoidable. B．Interracial lodging may have diverse outcomes. C．Students of different races are prejudiced against each other. D．Interracial lodging does more harm than good. 2.What does the Indiana University study show? A．Few white students like sharing a room with a black peer. B．Roommates of different races just don't get along. C．Interracial roommates are more likely to fall out. D．Assigning students' lodging randomly is not a good policy. 3.What does Alec Webley consider to be the "definition of integration"? A．The school randomly assigns roommates without regard to race. B．Students of different races are required to share a room. C．Interracial lodging is arranged by the school for freshmen. D．Lodging is assigned to students of different races without exception. 4.What can be inferred from Grace Kao’s saying about interracial lodging? A．Schools should be cautious when making decisions about student lodging. B．Students' racial background should be considered before lodging is assigned. C．Experienced resident advisors should be assigned to handle the problems. D．It is unscientific to make generalizations about it without further study.
As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(发电)and transmission (输送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around. The 19 th century saw land grants(政府拨地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died. Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now. So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species(物种) will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects. The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways. The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West. 1.What was the problem caused by the construction of the railways? A．Small towns along the railways became abandoned. B．Land in the West was hard to manage. C．Some railroad stops remained underused. D．Land grants went into private hands. 2.What is the major concern in the development of alternative energy according to the last two paragraphs? A．The use of money and power. B．The transmission of power. C．The conservation of solar energy. D．The selection of an ideal place. 3.What is the author’s attitude towards building solar plants? A．Disapproving. B．Approving. C．Doubtful. D．Cautious. 4.Which is the best title for the passage? A．How the Railways Have Affected the West B．How the Effects of Power Plants Can Be Reduced C．How Solar Energy Could Reshape the West D．How the Problems of the Highways Have Been Settled
You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to endure almost any disaster makes them seem like something out of a comic book. They're known as the black box. When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean on June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the box's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed. In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the box was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility. Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can stand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered. 1.What does the author say about the black box? A．It is an indispensable device on an airplane. B．The idea for its design comes from a comic book. C．Its ability to avoid disasters is incredible. D．It ensures the normal functioning of an airplane. 2.What does the underlined word in the 3rd paragraph mean? A．witness B．experience C．resist D．ensure 3.Why was the black box redesigned in 1965? A．New materials became available by that time B．Too much space was needed for its installation. C．The early models didn't provide the needed data. D．The early models often got damaged in the crash. 4.What do we know about the black boxes from Air France Flight 447? A．There is an urgent need for them to be reconstructed. B．There is still a good chance of their being recovered. C．They have stopped sending homing signals. D．They were destroyed somewhere near Brazil.

It's not a new phenomenon, but have you noticed how many nouns are being used as verbs? We all use them, often without noticing what we're doing. I was arranging to meet someone for dinner last week, and I said “I’ll pencil it in my diary”, and my friend said “You can ink it in”, meaning that it was a firm arrangement not a tentative one! Many of these new verbs are linked to new technology. An obvious example is the word fax. We all got used to sending and receiving faxes, and then soon started talking about faxing something and promising we'd fax it immediately. Then along came email, and we were soon all emailing each other madly. How did we do without it? I can hardly imagine life without my daily emails. Email reminds me, of course, of my computer and its software, which has produced another couple of new verbs. On my computer I can bookmark those pages from the World Wide Web that I think I'll want to look at again, thus saving all the effort of remembering their addresses and calling them up from scratch. I can do the same thing on my PC, but there I don't bookmark; I favorite—coming from “favorite pages”, so the verb comes from an adjective not a noun. Now my children bought me a mobile phone, known simply as a mobile and I had to learn yet more new verbs. I can message someone, that is, I can leave a message for them on their phone. Or I can text them, write a few words suggesting when and where to meet, for example. How long will it be before I can mobile them, that is, phone them using my mobile? I haven’t heard that verb yet, but I’m sure I will soon. Perhaps I’ll start using it myself! 1.“I’ll pencil it in my diary” in the second paragraph probably means . A．it was a firm arrangement B．he prefers a pencil to a pen C．the arrangement should be written as a diary D．it was an uncertain arrangement 2.A website address can be easily found if it has been______. A．favorited B．messaged C．emailed D．texted 3.Which of the following has not been used as a verb yet? A．message B．mobile C．email D．page 4.The best title for this passage is____. A．Technology and Language. B．Development of the English language C．New Technology and New words D．New Verbs from Nouns
This is a part from US President Barack Obama’s speech on May 14 at Bamard College in New York. … My last piece of advice – this is simple, but perhaps most important: 36. Nothing worthwhile is easy. No one of achievement has avoided failure – sometimes catastrophic failures. But they keep at it. They learn from mistakes. They don’t 37. When I first arrived on this 38, I was with little money, fewer options. But it was here that I tried to find my place in this world. I knew I wanted to make a difference, but it was 39 how in fact I’d go about it. But I wanted to do my part to 40 a better world. So even as I worked after graduation in a few 41 jobs here in New York, even as I went from motley (鱼龙混杂的)apartment to motley apartment, I 42. … And I wish I could say that this perseverance came from some innate (天生的)toughness in me. But the truth is, it was 43. I got it from 44 the people who raised me. I grew up as the son of a single mom who struggled to put herself through 45 and make ends meet. She had a marriage that fell apart; 46 went on food stamps at one point to help us 47. But she didn’t quit. And she earned her degree, and made sure that 48 scholarships and hard work, my sister and I earned 49. And 50, I met a woman who was assigned to advise me on my first summer job at a law firm. And she gave me such good advice that I married her. And Michelle and I gave everything we had to balance our careers and a 51 family. We made that marriage work. … So 52 it’s starting a business, or running for office, or 53 an amazing family, remember that making your 54 on the world is hard. It takes patience. It takes commitment. It comes with plenty of 55 and it comes with plenty of failures. 1. A．compete B．persevere C．struggle D．preservation
