Although we were all brought up in the same way, my brothers and sisters soon 42 their pressed flowers and insects. Unlike them, I had no 43 for music and languages. I was not an early reader and I could not do mental arithmetic.Before World War I, we spent our summer holidays in Hungary. I have only the 44 memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.I am a naturalist, not a scientist. I have a strong love for the natural world and my enthusiasm had led me into various investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people's observations and discoveries. Then something happens—that brings these observations together in my 45 mind. Suddenly you fancy you see the answer to the 46 , because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the 47 of scientific research.But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities 48 is self-discipline, a quality I lack. A scientist, up to point, can be made. A naturalist is 49 . If you can combine the two, you get the best of both worlds.III. Reading ComprehensionSection ADirections:For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.It’s hardly surprising that weather is a favorite topic for so many people around the world. It 50 where we choose to live, what we wear, our moods, and perhaps even our national features.A sunny day can lessen the deepest 51 , while very bad weather can destroy homes and threaten lives.The human race has always tried to 52 the weather, especially in areas of the world where there are many changes. Two popular traditional ways of predicting weather use pine cones(松果) and seaweed(海草). When the air has a high level of humidity(湿度), there is a higher chance of rain. When the humidity is low, there is more chance of 53 weather. Pine cones and seaweed feels dry when the humidity is low, 54 high humidity has the opposite effect.Today’s methods of prediction increasingly depend on 55 . Satellites, balloons, ships, aircraft and weather centers with 56 equipments send data to computers. The data is then 57 , and the weather is predicted. However, 58 this system can not predict weather for longer than about a week.A recent study by an Australian scientist suggests that certain people may have a special 59 for predicting weather. However, it is 60 that these people could use their talent in another way, since the same group had a lot of success in predicting changes in another system—the stock market.It 61 that a study of weather may also enable scientists to predict the sudden 62 of a disease. An Ebola epidemic (a kind of disease) in Uganda in the year 2000 came after the same rare 63 conditions that had been present before a sudden spread of the disease 6 years earlier. Efforts to 64 the spread of air-borne diseases such as foot and mouth are also strongly dependent on favorable wind conditions.50. A. shows B. affects C. predicts D. introduces51.

A. living B. working C. health D. weather64. A. encourage B. quicken C. limit D. shortenSection BDirections:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Being a victim of schoolyard violence can help pupils learn how to manage argument and develop their ability to get along with others, it was claimed.Helene Guldberg, associate lecturer in child development at the Open University, said trying to stop the “supposedly terrible dangers of bullying(欺负)” can do more harm than good. She insisted teachers should not break up “everyday playground argument”, saying chil dren should be left to deal with it themselves.In an on-line article, Dr. Guldberg said that bullying was “an experience that children need to develop”. But the comments were strongly criticized by anti-bullying campaigners.According to official figures, almost half of children claim they are bullied at school. One of the biggest studies of its kind by Ofsted showed 48 percent of young people had been orally or physically abused in the last year. It comes despite a number of government measures designed to crack down on the threats.Writing on a website, Dr. Guldberg said: “Teachers are increasingly taking the task of looking after children’s health and well-being rather than being allowed to get on with the task of educating them. Children are encouraged to assume their relationships with other children are damaging, and encouraged to look upon their classmates with suspicion.” She added: “If we treat children as if they cannot possibly cope with hurtful experiences, then we will likely to weaken their confidence and make them less likely to cope with difficult events in the future. In effect, we will prevent them from growing up.”The comments echo(附和) remarks made by teachers in recent years who claim the education system has been too focused on developin g children’s social skills at the expense of academic learning. But Sue Steel, national manager of the Anti-Bullying Alliance, said: “Children who are being bullied often find it difficult to tell anyone. Teachers can help by giving appropriate attention.”65. The underlined word “abused” in Para. 4 is similar in meaning to “_________”.A. criticizedB. attackedC. helpedD. judged66. Which of the following is TURE according to Helene Guldberg?A. Teachers should take the task of dealing with children’s argument.B. Children should be left to cope with their argument themselves.C. Children will gain their confidence if teachers manage their argument for them.D. Children can’t cope wit h difficult events after dealing with hurtful experiences themselves.67. Anti-bullying campaigners think that __________.A. teachers should help deal with children’s argument in a proper wayB. the government should take measures to stop children from being bulliedC. children will be prevented from growing up with too much school violenceD. teachers should develop children’s academic learning rather than social skills68. The passage mainly tells us that schoolyard violence is __________.A. difficult to get rid ofB. common among young peopleC. not necessarily bad for childrenD. harmful to children’s academic learning(B)69. If Jack wants to call his friend in Northern Ireland from London, he should dial ________.A. 0044 + area code (without 0) + local numberB. 048 + area code (without 0) + local numberC. area code (with 0) + local numberD. 00353 + the area code (without 0) + local number70. While travelling in Northern Ireland, you _________.A. can shop until 21:00 on ThursdaysB. needn’t leave a tip after receiving serviceC. can use American dollars to buy what you wantD. can draw money from banks from 9:00 to 16:30 every day71. Which of the following is TRUE according to the above Visitor Guide?A. A German needn’t a passport to travel in Northern Ireland.B. A visitor can dial 999 in emergency situations while in Northern Ireland.C. Any European can get healthcare in Northern Ireland at a reduced cost or free of charge.D. A visitor will be charged£3 for leaving luggage in Belfast Welcome Centre for 6 hours.(C)Lots of bacteria can grow in the seemingly unfriendly environment under glaciers(冰川), a region formerly considered free of much biology. This finding by glaciologists working in Switzerland could help solve some puzzles of the last ice age and point the way for finding life on other planets.Bacteria with odd lifestyles have been under increasing study lately, with most research focused on the species which prefer hot homes. The new study shifts attention to the other end of the thermometer(温度计). The exciting thing is the idea of pushing the window of acceptable bacterial environments a little bit farther open.Researchers have previously collected small numbers of bacteria from ice in Antarctica and Greenland, but they could not determine whether these were active bacteria or just frozen cells blown in by wind. In contrast, the earth beneath two Swiss glaciers harbors large colonies of bacteria —hundreds of millions of cells per gram—that appear to be growing at0℃.Scientists followed upon these findings by taking samples of ice, water, and earth at two mountain glaciers. They found that earth beneath the glaciers contained much larger populations of bacteria than did surface and inner part of ice. Those findings indicate that the bacteria were growing at the bottom of the glacier and are not something washed in while the scientists drilled through the ice.Looking at the bacteria under a microscope(显微镜), the researchers found that many were in the process of dividing, and healthy under the ice. The bacteria might break down minerals and plant remains originally buried beneath the glacier or later washed in by water going slowly through the ice, scientists say.“Some of the assumptions we have made in the past now must be seriously questioned,” say researchers. “If bacteria can live under glaciers o n Earth, why not on other planets? The new study points out in many ways that the bottoms of glaciers are probably quite good environments from the point of view of bacteria. So, maybe the bottom of the ice sheets on other planets would be a sensible place to try if you’re going to look for life on them.”72. What is special about the new study on bacteria?A. It focuses on the bacteria in hot environments.B. It opens the windows of the bacterial labs wider.C. It pays more attention to the bacteria in the thermometer.D. It changes scientists’ view about the environment bacteria exist in.73. Which of the following facts proves that bacteria under glaciers are alive?A. Water is going slowly through the ice.B. The drills used by scientists are free of bacteria.C. Many of the bacteria are in the process of dividing.D. The earth beneath the glacier contains more bacteria.74. From the passage we can learn that ________.A. bacteria disappear in the inner part of iceB. bacteria must be also alive on other planetsC. bacteria can grow in extreme weathersD. bacteria grow by breaking themselves down75. The passage is mainly about the possibility of the existence of life _________.A. under the seaB. in hot waterC. on other planetsD. under glaciers Section CDirections:Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.Many men are devoted to exercise to build up their bodies, but the phrase “use it or lose it” applies to more than just the muscle in our bodies—it also applies to our brains. Here are 5 tips that can help our brains stay sharp.76. _________It plays an important role in all cognitive activities, including reading, reasoning and mental calculation. There are several types of its work in the brain. Taken together, these are the cognitive skills we may notice most when they begin to fail. To keep a good memory, you need to train for it, which can be easier than you think. Listening to music is enjoyable. By choosing a song you don’t know and memorizing the lyrics, you improve your memory skills.77. _________It is necessary in nearly all daily tasks and it enables you to focus despite noise and to think about several things at once. We can improve the skill by simply changing our routines. Change your course to work or reorganize your desk—both will force your brain to wake up and pay attention again.78. _________It will increase your ability to recognize, remember and understand words. With regular practice, you can expand your knowledge of new words and more easily think of words to say because they will come to you more naturally. For example, if you usually only read the sports section, try reading a fe w business articles. You’ll learn new words, and by using them you can also exercise your brain.79. _________You can also exercise your brain by taking advantage of your environment. Try walking into a room and picking out five items and their locations. When you exit the room, try to remember all five items and where they are located. Too easy? Wait two hours and try to remember those items and their locations. Analyzing what you saw will force you to use your memory and train your brain to focus on your surroundings.80. _________It helps you make decisions, build up hypotheses and consider the possible consequences of your actions.Activities in which you must define a strategy to reach a desired outcome and calculate the right moves to reach the solution in the shortest possible time are actually fun activities you can do daily. For example, playing video games requires you to come up with a strategy so as to advance to the next level.Section DDirections:Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.In so many ways, cyberspace(网络空间) mirrors the real world. People ask for information, play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even love.Unlike the real world, however, your knowledge about a person is limited to words on acomputer screen. Identity and appearance mean very little in cyberspace. Rather, a person’s thoughts —or at least the thoughts they type—are what really count. So even the shyest person can become a chat-room star.Usually, this “faceless” communication doesn’t create problems. Identity doesn’t really matter when you’re in a chat room discussing politics or hobbies. In fact, this emphasis on the ideas themselves makes the Internet a great place for exciting conversation. Where else can so many people come together to chat about their interests?But some Internet users want more than just someone to chat with. They’re looking for serious love relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Some of these relationships actually succeed. Others fail miserably.Supporters of online relationships claim that the Internet allows couples to get to know each other intellectual ly first. Personal appearance doesn’t get in the way.But critics of online relationships argue that no one can truly know another person in cyberspace. Why? Because the Internet gives users a lot of control over how others view them. Internet users can ca refully craft their words to fit whatever image they want to give. And they don’t have to worry about what their “faceless” communication is doing for their image. In a sense, they’re not really themselves.All of this may be fine if the relationship stays in cyberspace. But not knowing a person is a big problem in a love relationship. With so many unknowns, it’s easy to let one’s imagination “fill in the blanks.” This inevitably leads to disappointment when couples meet in person. How someone imagines an online friend is often quite different than the real person.So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll: “Life in the real world is far richer than anything you’ll find on a computer screen.”(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)81. We learn about a person in cyberspace only through ______________________________.82. Why is the Internet a great place for exciting conversation?83. What makes online love relationship often fail?84. From the passage we can learn that the writer __________________________ looking for loveon the Internet.第Ⅱ卷（共45分）I.

Although we were all brought up in the same way, my brothers and sisters soon 42 their pressed flowers and insects. Unlike them, I had no 43 for music and languages. I was not an early reader and I could not do mental arithmetic.Before World War I, we spent our summer holidays in Hungary. I have only the 44 memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.I am a naturalist, not a scientist. I have a strong love for the natural world and my enthusiasm had led me into various investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people's observations and discoveries. Then something happens —that brings these observations together in my 45 mind. Suddenly you fancy you see the answer to the 46 , because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the 47 of scientific research.But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities 48 is self-discipline, a quality I lack. A scientist, up to point, can be made. A naturalist is 49 . If you can combine the two, you get the best of both worlds.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.It’s hardly surprising that weather is a favorite topic for so many people around the world. It50 where we choose to live, what we wear, our moods, and perhaps even our national features.A sunny day can lessen the deepest 51 , while very bad weather can destroy homes and threaten lives.The human race has always tried to 52 the weather, especially in areas of the world where there are many changes. Two popular traditional ways of predicting weather use pine cones(松果) and seaweed(海草). When the air has a high level of humidity(湿度), there is a higher chance of rain. When the humidity is low, there is more chance of 53 weather. Pine cones and seaweed feels dry when the humidity is low, 54 high humidity has the opposite effect.Today’s methods of prediction increasingly depend on 55 . Satellites, balloons, ships, aircraft and weather centers with 56 equipments send data to computers. The data is then 57 , and the weather is predicted. However, 58 this system can not predict weather for longer than about a week.A recent study by an Australian scientist suggests that certain people may have a special59 for predicting weather. However, it is 60 that these people could use their talent in another way, since the same group had a lot of success in predicting changes in another system—the stock market.It 61 that a study of weather may also enable scientists to predict the sudden 62 of a disease. An Ebola epidemic (a kind of disease) in Uganda in the year 2000 came after the same rare 63 conditions that had been present before a sudden spread of the disease 6 years earlier. Efforts to 64 the spread of air-borne diseases such as foot and mouth are also strongly dependent on favorable wind conditions.崇明县2012届高考模拟试卷高三英语共14页第3页50.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Being a victim of schoolyard violence can help pupils learn how to manage argument and develop their ability to get along with others, it was claimed.Helene Guldberg, associate lecturer in child development at the Open University, said trying to stop the “supposedly terrible dangers of bullying(欺负)” can do more harm than good.She insisted teachers should not break up “everyday playground argument”, saying children sho uld be left to deal with it themselves.In an on-line article, Dr. Guldberg said that bullying was “an experience that children need to develop”. But the comments were strongly criticized by anti-bullying campaigners.According to official figures, almost half of children claim they are bullied at school. One of the biggest studies of its kind by Ofsted showed 48 percent of young people had been orally or physically abused in the last year. It comes despite a number of government measures designed to crack down on the threats.Writing on a website, Dr. Guldberg said: “Teachers are increasingly taking the task of looking after children’s health and well-being rather than being allowed to get on with the task of educating them. Children are encouraged to assume their relationships with other children are damaging, and encouraged to look upon their classmates with suspicion.”She added: “If we treat children as if they cannot possibly cope with hurtful experiences, then we will likely to weaken their confidence and make them less likely to cope with difficult events in the future. In effect, we will prevent them from growing up.”The comments echo(附和) remarks made by teachers in recent years who claim the education system has been too focused on developing child ren’s social skills at the expense of academic learning. But Sue Steel, national manager of the Anti-Bullying Alliance, said: “Children who are being bullied often find it difficult to tell anyone. Teachers can help by giving appropriate attention.”65.

A visitor will be charged £3 for leaving luggage in Belfast Welcome Centre for 6 hours.(C)Lots of bacteria can grow in the seemingly unfriendly environment under glaciers(冰川), a region formerly considered free of much biology. This finding by glaciologists working in Switzerland could help solve some puzzles of the last ice age and point the way for finding life on other planets.Bacteria with odd lifestyles have been under increasing study lately, with most research focused on the species which prefer hot homes. The new study shifts attention to the other end of the thermometer(温度计). The exciting thing is the idea of pushing the window of acceptable bacterial environments a little bit farther open.Researchers have previously collected small numbers of bacteria from ice in Antarctica and Greenland, but they could not determine whether these were active bacteria or just frozen cells blown in by wind. In contrast, the earth beneath two Swiss glaciers harbors large colonies of bacteria—hundreds of millions of cells per gram—that appear to be growing at 0℃.Scientists followed upon these findings by taking samples of ice, water, and earth at two mountain glaciers. They found that earth beneath the glaciers contained much larger populations of bacteria than did surface and inner part of ice. Those findings indicate that the bacteria were growing at the bottom of the glacier and are not something washed in while the scientists drilled through the ice.Looking at the bacteria under a microscope(显微镜), the researchers found that many were in the process of dividing, and healthy under the ice. The bacteria might break down minerals and plant remains originally buried beneath the glacier or later washed in by water going slowly through the ice, scientists say.“Some of the assumptions we have made in the past now must be seriously questioned,” say researchers. “If bacteria can live under glaciers on Earth, why not on other planets? The new study points out in many ways that the bottoms of glaciers are probably quite good environments from the point of view of bacteria. So, maybe the bottom of the ice sheets on other planets would be a sensible place to try if you’re going to look for life on them.”72. What is special about the new study on bacteria?A. It focuses on the bacteria in hot environments.B. It opens the windows of the bacterial labs wider.C. It pays more attention to the bacteria in the thermometer.D. It changes scientists’ view about the environment bacteria exist in.73. Which of the following facts proves that bacteria under glaciers are alive?A. Water is going slowly through the ice.B. The drills used by scientists are free of bacteria.C. Many of the bacteria are in the process of dividing.D. The earth beneath the glacier contains more bacteria.74. From the passage we can learn that ________.A. bacteria disappear in the inner part of iceB. bacteria must be also alive on other planetsC. bacteria can grow in extreme weathersD. bacteria grow by breaking themselves down75. The passage is mainly about the possibility of the existence of life _________.A. under the seaB. in hot waterC. on other planetsD. under glaciersSection CDirections: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.Many men are devoted to exercise to build up their bodies, but the phrase “use it or lose it”applies to more than just the muscle in our bodies—it also applies to our brains. Here are 5 tips that can help our brains stay sharp.76. _________It plays an important role in all cognitive activities, including reading, reasoning and mental calculation. There are several types of its work in the brain. Taken together, these are the cognitive skills we may notice most when they begin to fail. To keep a good memory, you need to train for it, which can be easier than you think. Listening to music is enjoyable. By choosing a song you don’t know and memorizing the lyrics, you improve your memory skills.77. _________It is necessary in nearly all daily tasks and it enables you to focus despite noise and to think about several things at once. We can improve the skill by simply changing our routines. Change your course to work or reorganize your desk—both will force your brain to wake up and pay attention again.78. _________It will increase your ability to recognize, remember and understand words. With regular practice, you can expand your knowledge of new words and more easily think of words to say because they will come to you more naturally. For example, if you usually only read the sports section, try reading a few business articles. You’ll learn new words, and by using them you can also exercise your brain.79. _________You can also exercise your brain by taking advantage of your environment. Try walking into a room and picking out five items and their locations. When you exit the room, try to remember all five items and where they are located. Too easy? Wait two hours and try to remember those items and their locations. Analyzing what you saw will force you to use your memory and train your brain to focus on your surroundings.80. _________It helps you make decisions, build up hypotheses and consider the possible consequences of your actions.Activities in which you must define a strategy to reach a desired outcome and calculate the right moves to reach the solution in the shortest possible time are actually fun activities you can do daily. For example, playing video games requires you to come up with a strategy so as to advance to the next level.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.In so many ways, cyberspace(网络空间) mirrors the real world. People ask for information, play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even love.Unlike the real world, however, your knowledge about a person is limited to words on a computer screen. Identity and appearance mean very little in cyberspace. Rather, a person’s thoughts—or at least the thoughts they type—are what really count. So even the shyest person can become a chat-room star.崇明县2012届高考模拟试卷高三英语共14页第7页Usually, this “faceless”communication doesn’t create problems. Identity doesn’t really matter when you’re in a chat room discussing politics or hobbies. In fact, this emphasis on the ideas themselves makes the Internet a great place for exciting conversation. Where else can so many people come together to chat about their interests?But some Internet users want more than just someone to chat with. They’re looking for serious love relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Some of these relationships actually succeed. Others fail miserably.Supporters of online relationships claim that the Internet allows couples to get to know each other intellectually first. Personal appearance doesn’t get in the way.But critics of online relationships argue that no one can truly know another person in cyberspace. Why? Because the Internet gives users a lot of control over how others view them. Internet users can carefully craft their words to fit whatever image they want to give. And they don’t have to worry about what their “faceless” communication is doing for their image. In a sense, they’re not really themselves.All of this may be fine if the relationship stays in cyberspace. But not knowing a person is a big problem in a love relationship. With so many unknowns, it’s easy to let one’s imagination “fill in the blanks.” This inevitably leads to disappointment when couples meet in person. How someone imagines an online friend is often quite different than the real person.So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll: “Life in the real world is far richer than anything you’ll find on a computer screen.”(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)81. We learn about a person in cyberspace only through ______________________________.82. Why is the Internet a great place for exciting conversation?83. What makes online love relationship often fail?84. From the passage we can learn that the writer __________________________ looking forlove on the Internet.第Ⅱ卷（共45分）I.
