They are also known as lady beetles or ladybird beetles. They come in many different colours and patterns, but the best-known in North America is the seven-spotted ladybug, with its shiny, red-and-black body.In many cultures, ladybugs are thought to be good luck. Most people like them because they are pretty, lovely and do no harm to human beings. But farmers love them because they eat aphids and other plant-eating pests. One ladybug can eat up 5,000 insects in its lifetime!Most ladybugs have dome-shaped bodies with six short legs. Depending on the kind, they can have spots, stripes, or nothing at all. Seven-spotted ladybugs are red or orange with three spots on each side and one in the middle. They have a black head. Ladybugs are colourful for a reason. They tell the enemy:“Eat something else! I taste terrible.”When threatened, they may play dead. Birds are ladybugs' main predators(捕食者), but they are also eaten by frogs, spiders, and dragonflies.第 1 页Ladybugs are happy in many different places,including grasslands,forests, cities, suburbs, and along rivers. Seven-spotted ladybugs are native to Europe but were brought to North America in the mid-1900s.Ladybugs are most active from spring until fall. When the weather turns cold, they look for a warm place to hibernate,such as in rotting logs,under rocks,or even inside houses. These hibernating places can have thousands of ladybugs.The name “ladybug”was given by European farmers who prayed to the Virgin Mary when pests began eating their crops. After ladybugs came and wiped out the invading insects, the farmers named them “beetle of Our Lady”. This later was shortened to “lady beetle”and “ladybug”.1. The underlined word “aphids”in Paragraph 2 is probably a kind of .A.pestB.birdC.plantD.tree2.

The homeless man, who I thought was hungry himself, went into the store. And what he did brought 16 to me and my wife. He went into the store and,with perhaps all the 17 he may have had, bought a can of dog food and fed that dog.I know that this story isn't as 18 as most stories, but it plays a great part in our lives.

In a special school for the hearing-impaired（听觉受损的）, he learned sign language and got to mix with other disabled children, However, the sight of all the disabled children communicating with one another upset his mother. She wanted him to lead a normal life. So after speaking to an advisor,she sent him to private classes where he learned to read lips and pronounce words. Later on, Adrian’s parents decided to send him to a regular school. But the headmaster tried to prevent them from doing so,saying regular schools couldn't take care of a special needs student.His parents were determined to take the risk and pushed him hard to go through his work every day because they wanted to prove that,given the opportunity, he could do anything.Adrian made the grade and got accepted. It was a big challenge.The pace（节奏）was faster so he had to sit at the front of the class and really pay attention to the teacher, which wasn’t always easy. But he stuck to it and did a lot of extra work after school.The efforts made by Adrian and his parents paid off. Adrian graduated with good grades and got into a lop high school.He also achieved a lot in life outside school.He developed a love for the outdoors and went to Nepal to climb mountains.He even entered the World Yacht Race 05/06-being the first hearing-impaired Asian to do so.But none of these achievements would have been possible without one of the most important lessons from his mother. “If you believe in yourself and work hand, you can achieve great results.” She often said.4.How did Adrian communicate with other children in the special school?A.

He reached his goals in spite of his disability.D. He took part in the World Yacht Race 05/06.CUsing too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways.You may wonder how paving（铺砌）amad can lead to less useable fresh water,A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It comes from underground.The more roads and parking lots we pave the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages. Drier climates are of course more likely to have droughts（干旱）than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day.Run your dishwasher（洗碗机）only when it is full. Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.8.Which of the following is most likely to lead to less groundwater?ing river water.B.Throwing batteries away.C. Paving parking lots.D.Throwing rubbish into lakes.9. What can be inferred about the water supply from the text?A. All water shortages are due to human behavior.A.To tell us how to run a dishwasher.B. To show us how to fix leaks at home.C.To prove what drinking glass is best for us.D. To suggest what we do to save water at home.11.What is the text mainly about?A. Why paving roads reduces our water.B. How much we depend on water to live.C. Why droughts occur more in dry climates.D. How human activity affects our water supply.DAnimals 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 sines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 reach. 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）leave, and catch pricklecontains poisonous venom.A single experience with this kind of plant will teach an animal to stay away from it in the future.12.Why does the holly plant have more spines on the lower leaves?A. Most animals are not tall enough.B. Most animals are not clever enough.C.Most animals like the lower leaves only.D.Most animals can gel the lower leaves easily.13. What do oak trees use to defend themselves?A. Chemical means. B Physical means.C.Bitter chemicals.D.Sandy materials.14. 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.15. What is the best title for the text?A. Plants and AnimalsB. Attacks and DefensesC. How Animals Eat Plant LeavesD.How Plants Defend Themselves第二节（共5小题；每小题2分，满分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。

5．压缩语段1．(2011·马鞍山高三质检)根据下面的新闻材料，拟一条一句话新闻。
(不超过20字)“红段子”就要来了！在有关部委和几大移动运营商的联合高调推动下，中国手机短信有望“全国山河一片红”。
一场名为“红段子现象——网络时代的中国文化精神和产业走向”的座谈会，在农历新年临近之际，拉开序幕。
其受重视程度，从参会人员可见一斑：工业与信息化部副部长奚国华、国家广播电影电视总局副局长胡占凡、中国移动副总裁李跃、中国联通副总经理姜正新、中国电信副总经理孙康敏等。
在会上，除了发布《“红段子”现象：网络时代的中国文化精神》之外，中国移动通信联合会执行副会长谢麟振提出建议：与会单位共同组建宏观网络文明(“红段子”)产业发展中心。
未来重点培养和发展“百万种子选(写)手”和“千万群众选(写)手”，实现“亿万群众转发参与”。
中国移动通信集团广东公司总经理徐龙撰文称：具有思想性和知识性，内容健康向上，形式短小精悍，效果催人奋进的短信，就是“红段子”。
一句话新闻：_____________________________________________________________ 答案“红段子”有望在中国手机短信中流行。
(关键词：红段子、有望、流行) 2．(2011·浙江调研)从下列文字中，概括“高纯度”饮用水的缺点。
(不超过35个字)人们饮用纯净水的初衷，是避免污染，但纯净水对人体健康的危害绝不可小视。
科学家指出，饮纯净水，无异于让肾脏“下岗”。
据专家分析，现在市场上的各类所谓“高纯度”饮用水，在消除细菌、有机污染物及致癌物质等的制造过程中，也不可避免地将大量人体必需的微量元素消除得一干二净。
众所周知，“水至清则无鱼”，试想连鱼都养不活的水，于我们人类能有多大好处呢？研究表明，“高纯度”饮用水的凝聚态结构，还会把人体内原有的微量元素淋洗出去。
这样一来就减弱了人体的免疫力，可以引发许多疾病。

I was left wondering if people 38 me and saw only happy teeth.Later that day at home, I began to 39 my teeth again. I felt upset. I thought my life would be somehow better if my teeth were not happy.

We would start from home, walking two blocks to the rail station. We’d take the train into th e city center, then a bus, switching to the tram, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn’t like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom’s friend was waiting to give us a ride home—our first car ride of the day.The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal (多方式的). She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence—the product of a childhood not spent exploring subway tunnels.Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just light-rail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox—and often an inadequate one, limiting both your mobility and your wallet.On Transportation Days, we might stop for lunch on Chestnut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where’s the stop, and will I get wet when we go under the river?I’m writing this right now on an airplane, a means we didn’t try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me.55. Which was forbidden by Mom on Transportation Days?A. Having a car ride.B. Taking the train twice.C. Buying more than one toy.D. Touring the historic district.56. According to the writer, what was the greatest benefit of her Transportation Days?A. Building confidence in herself.B. Reducing her use of private cars.C. Developing her sense of direction.D. Giving her knowledge about vehicles.57. The underlined word “paralyzed” (in Para. 5) is closest in meaning to “_______”.A. displayedB. justifiedC. ignoredD. ruined58. Which means of transportation does the writer probably disapprove of?A. Airplane.B. Subway.C. Tram.D. Car.阅读表达[1] Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that cellphones, power lines and WiFi could be responsible for a range of illnesses.[2] Camilla Rees, an investment banker in the US, moved out of her apartment. She said that when her neighbors moved in and installed a WiFi router (路由器) she lost her ability to think clearly. Since then, she’s been on a movement against low-level electromagnetic fields (电磁场), or EMFs. And she’s not alone. Millions of people say they suffer from headaches and depression when they’re too close to cellphones or other sources of EMFs. If these fears are justified (有正当理由的), then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into WiFi hotpots.[3] Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors (肿瘤). But others believe _________________. Dr Martha Linet at the US National Cancer Institute has reached a different conclusion. “We don’t have the evidence that there’s much danger,” said Linet.[4] Studies so far suggest a weak connection between EMFs and illness — so weak that it might not exist at all. A multinational investigation (调查) of cellphones and brain cancer has been underway for several years. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.[5] According to Robert Park, a professor of physics, the magnetic waves（电磁波）aren’t nearly powerful enough to break apart DNA, w hich is how known threats, such as UV rays and X-rays, cause cancer.76.

The new program is known as the KNFB Reader app. It can help users listen to the sound of 11 material. Blind people say the KNFB Reader app will make life much 12 . They say it will help with everything 13 reading restaurant menus to studying papers in the classroom. The KNFB Reader makes use of new pattern recognition and image-processing technology, and new hardware for smartphones. People using the app can 14 , or change the position of the camera and read materials out loud. Users say the app has given some people greater 15 . The Reuters news service says these users made the 16 on social media sites such as Twitter. One user, named Gordon Luke, reported that he was able to use the app to read his voting card for the recent referendum in Scotland. Ray Kurzweil told Reuters that the app will be 17 for Android mobile devices in the coming months. He said he may 18 build a version of the app for Google Glass. Google Glass is a small computer screen that can be 19 to eyeglasses. It is able to take photographs, record video and play sound. Ray Kurzweil 20 that ―Google Glass makes sense because you 21 the camera with your head.‖ Mr. Kurzweil started working on what he called ―reading machines‖ in the early 1970s. The idea came after speaking with a blind person who expressed 22 with the lack of technology to assist blind people. 1Mr. Kurzweil‘s first reading machine was the 23 of a washing machine. It cost $50,000. The technology has continued to improve over the past 20 years. The new smartphone app can 24 and take printed material in one language and change it to another language. But it was not available on a mobile device until now. In the past, it cost more than $1,000 to use the software app with a camera and a mobile phone. The 25 of the KNFB Reader app comes at a time when the technology industry is facing 26 . Criticssay the industry is 27 concerned about making software programs for sharing photos and video games. Bryan Bashin leads the non-profit group Lighthouse for the Blind and Visually Impaired in San Francisco. He is also blind. He says the KNFB app shows the positive impact that 28 can have. He says there are times in his life when he wishes the KNFB app were available to him. He adds that the ability to gain information quickly with something that 29 in your pocket at a fast speed will be, what he 30 , ―a game changer.‖ 11.

But a new study suggests being handsome may not always work in a man‘s favour – at least when it comes to his career.The research claims that attractive men are less likely to be given a job in a competitive workplace because they intimidate bosses.?It‘s not always an advantage to be pretty,‘ says Marko Pitesa, an assistant professor at the University of Maryland. ?It can backfire if you are perceived as a threat.‘Interestingly, in Pitesa‘s study, it was male attractiveness in particular, rather than female beauty, that made the most difference. If the interviewer expected to work with the candidate as part of a team, then he preferred good-looking men.However, if the interviewer saw the candidate as a potential competitor, the interviewer discriminated in favor of unattractive men.In the first experiment, 241 adults were asked to evaluate fictional job candidates based on fake qualifications and experience, in an online setting.2Men evaluated men and women evaluated women. Interviewers were primed to either think of the candidate as a future co-operator or competitor, and they were given a computer-generated headshot that was either attractive or unattractive.A second experiment involved 92 people in a lab. They were asked to evaluate future competitors or partners in a quiz game, based on credentials that included sample quiz answers, and they saw similar headshots.The patterns of discrimination based on perceived self-interest were the same.Another test opened up to include men interviewing women and women interviewing men.There was still a preference to cooperate with the attractive man and compete against the unattractive man.A final experiment used photographs of actual European business school students, vetted for attractiveness, and found the same pattern.The results suggest that interviewers were not blinded by beauty, and instead calculated which candidate would further their own career.?The dominant theoretical perspective in the social sciences for several decades has been that biases and discrimination are caused by irrational prejudice,‘ Pitesa says.?The way we explain it here, pretty men just seem more competent, so it is actually subjectively rational to discriminate for or against them.‘On a deeper level, she adds, the behavior remains irrational, since there‘s no evidence that a real link exists between looks and competence.31. According to the first three paragraphs, why do attractive men sometimes have difficulty finding a job?A. They are considered as potential threatens.B. They are considered as potential distractions.C. They seem to be hard to cooperate with.D.They seem to be uncompetitive. 32. According to the results of the three experiments, which of the following is true?A. Interviewees‘ attractiveness blinds the interviewers.B. Interviewees ?attractiveness doesn‘t play any role in interviews.C. Interviewees hold advantages when interviewers are picking their team members.D. Interviewers prefer unattractive people when they are expanding their teams. 33. The passage focuses on ________.A. why attractive men are less competitiveB. why attractive women are more likely to land a jobC. how irrational prejudice towards appearance worksD. whether looks are related to competence 四．任务型阅读Cycling is the new golfTraditionally, business associates would get to know each other over a round of golf. But road cycling is fast catching up as the preferred way of networking for the modern professional. A growing number of corporate-sponsored charity bike rides and city cycle clubs are providing an ideal opportunity to talk shop with like-minded colleagues andclients(客户) while discussing different bike frames. Many believe cycling is better than golf for building lasting working relationships, or landing a new job, because it is less competitive.―When you play golf with somebody you have to decide if you‘re going to beat them, or let them beat you,‖ says Peter Murray, a former architect. ―If they‘re a client and you don‘t want to beat them you have to sort of cheat in order to lose. That seems to me not a good way of doing things.‖ Group cycling, and especially long-distance riding, is a shared experience, Mr. Murray says. Riders often work together and help each other out, taking turns to be at the front so that the riders in their slipstream can save almost a third of the effort needed to travel at the same speed.3In 2005, Mr. Murray, who is a keen long-distance rider, founded the annual Cycle to Cannes bike ride. This six-day charity event brings together architects who want to cycle 1,500km from London to the MIPIM property fair in southern France each March. It has raised ￡1.5m for a range of charities in Britain and abroad.How someone rides a bike can give you a real insight into what a person is like, says Jean-Jacques Lorraine, a regular participant of Cycle to Cannes. ―There is an easy rhythm about conversations on a bike. I often find I‘m saying things on a bike which I wouldn‘t normally say, and equally I‘ve been confided in when I wasn‘t expecting it. Some riders are very single-minded, others more collaborative; some are tactical, others an open book.‖Many long-distance bike riders say cycling, especially over long distances, simply makes them feel good; it lifts their mood and concentrates things down to the essentials. ―The pattern of fuelling, riding, fuelling, arriving, celebrating, sleeping and fuelling again putsall the focus on riding and the company of your fellow riders,‖ says Simon Mottram, chief executive of Rapha, a premium cycling-clothes brand. The simple repetitiveness eases the stresses and pressures of normal life, he adds.Why do cycle rides lend riders so well to networking and making professional contacts? ―Grabbing a quick lunch or drink after work, while great for different reasons doesn‘t give you long enough to get to know someone,‖ he says. Mr. Murray believes long rides break down conventional hierarchical(等级制度) barriers. ―A younger rider can be cycling along with a chief executive and help them in some way and you get a reversal of the relationship. This changes the relationship when they are off the ride too.‖Perhaps the most compelling reason why cycling is a good way to network is because, for many professionals, it‘s a passion and a way of life they share. ―Getting out on the bike is what we‘re all dreaming of doing while we‘re sitting at our computers,‖ says Mr Mottram.
