The visitors here are greatly impressed by the fact that _______ people from all walks of life are working hard for _____ new Jiangsu.

Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn’t have to be the outcome. Water shortages do not have to trouble the world — if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy. 36. What is the real cause of the potentials water crisis. A. Only half of the world’s water can be used. B. The world population is increasing faster and faster. C. Half of the world’s water resources have been seriously polluted. D. Humanity has not placed enough value on water resources. 37. As is indicated in the passage, the water problem _________ . A. is already serious in certain parts of the world. B. has been exaggerated by some experts in the field C. poses a challenge to the technology of building reservoirs (水库) D. is underestimated by government organizations at different levels 38. According to the author, the water price should _______ . A. be reduced to the minimum B. stimulate domestic demand C. go with its real value D. take into account the occurrences of droughts 39. In order to raise the efficiency of the water supply, measures should be taken to ______ . A. guarantee full protection of the environment B. centralize the management of water resources C. increase the sense of responsibility of agencies at all levels D. encourage local and regional water resources 【答案】36. D 37. A 38. C 39. B 【解析】 【导语】这是一篇说明文。人类面临水危机，原因在于未重视水资源，应合理定价、优化供水方式并集中管理水资源。 【36题详解】 细节理解题。根据第二段第二句“Water shortages do not have to trouble the world — if we start valuing water more than we did in the past.(如果我们开始比过去更重视水资源，水资源短缺就不必困扰世界)”可知，潜在的水危机真正原因是人类过去没有给予水资源足够的重视。故选D。 【37题详解】 推理判断题。根据第一段第二句“Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies.(然而，短缺和干旱的发生正在一些地区造成饥荒和困苦，工业和农业副产品正在污染水源)”可知，水资源问题在世界某些地区已经很严重了。故选A。 【38题详解】 细节理解题。根据第三段第一句“Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value.(相反，除了穷人的家庭用水需求外，对于所有其他用水，政府应该对水定价以反映其实际价值)”可知，作者认为水价应该与其实际价值相符。故选C。 【39题详解】 细节理解题。根据最后一段最后一句“Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.(与其在数百甚至数千个关注用水各个方面的地方、地区和国家机构之间分散控制权，各国应该设立中央机构来协调水政策)”可知，为了提高供水效率，应该采取措施集中管理水资源。故选B。 B Federal regulators(调整者) Wednesday approved a plan to create a nationwide emergence alert (警报) system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates（估计） more than 48 billion text messages are sent each month. The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation’s emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers –telecommunications companies is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three different types of messages, according to the rules. The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架) emergencies, or so-called Amber Alerts. The service could be in place by 2010. 40. What is the purpose of the approved plan? A. To warn people of emergencies via messages. B. To popularize the use of cell phones. C. To estimate the monthly number of messages. D. To promote the wireless industry. 41. The improvement to the present system is in the charge of ____. A. CTIA B. the Warning Alert and Response Network C. FCC D. federal regulators 42. The carriers’ participation in the system is determined by _____. A. the US federal government B. mobile phone users C. the carriers themselves D. the law of the United States 43. Which of the following would be the best title for the text? A. Cell Phone Alerts Protecting Students B. Cell Phone Alerts by Wireless Industry C. Cell Phone Alerts of National Disasters D. Cell Phone Alerts Coming Soon 【答案】40. A 41. C 42. C 43. D 【解析】 【分析】本文为新闻报道。介绍了美国联邦监管机构批准了一项将通过手机短信创建一个全国性的紧急警报系统的计划，。 【40题详解】 细节理解题。根据Federal regulators(调整者) Wednesday approved a plan to create a nationwide emergence alert (警报) system 描述，可知选A。 【41题详解】 细节理解题。根据The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.描述，可知选C 【42题详解】 细节理解题。根据The program would be optional for cell phone users. They also may not be charged for receiving alerts.描述，可知选C。 【43题详解】 主旨大意题。这篇短文主要介绍了通过的一项关于手机的计划，告诉我们手机提醒时代即将来临。故选D。 C While all my classmates seen to be crazy about a one-way ticket to Mars (火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return? Steve Minear, UK Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory… For scientists there is another reason. Their observations and research will probably lead to great scientific achievements. Donal Trollop, Canada There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony (殖民地) on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches (发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world. Enough supplies can be sent on ahead, and every two years more supplies and more people will be sent to the new colony. Mars has all the materials for a colony to produce or make everything it needs, and Mars is far more pleasant than the other planets in the outer space. Paul Davies, USA 44. The main purpose of Steve Minear’s writing is . A. to report his classmates’ discussion B. to invite an answer to his question C. to explain the natural state of Mars D. to show his agreement on going to Mars 45. Which of the following best states Donal Trollop’s idea? A. There is a plan to send humans to Mars. B. There are many reasons for going to Mars. C. Scientists become famous by doing research on Mars. D. It is possible to build an Earth-like environment on Mars. 46. Paul Davies points out that . A. humans need only a one-way ticket to Mars B. two-way trips to Mars will be made safe soon C. it is easy to reduce the danger and cost of flights to Mars D. it is cheap to build an everlasting human settlement on Mars 47. What does Paul Davies think of human existence on Mars? A. Humans will have to bring all they need from the Earth. B. Humans will find Mars totally unsuitable for living. C. Humans can produce everything they need. D. Humans can live longer in the colony on Mars. 【答案】44. B 45. B 46. A 47. C 【解析】 【导语】本文为议论文，主要围绕三位作者对人类移民火星的不同观点展开讨论。 【44题详解】 推理判断题。由第一段中“Can anybody explain to me just why people would go to Mars, never to return? (有人能向我解释为什么人们会去火星，永远不会回来吗？)”可知，Steve Minear通过质疑他人观点并抛出问题，目的是邀请他人回答自己的疑问。故选B项。 【45题详解】 主旨大意题。由第二段“Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory… For scientists there is another reason. Their observations and research will probably lead to great scientific achievements. (以下是你能想到的事情：探索异国和独特环境的愿望，作为第一个开拓新世界的人类的兴奋，对名望和荣耀的期望……对于科学家来说还有另一个原因。他们的观察和研究可能会带来巨大的科学成就)”可知，Donal Trollop在第二段列举了探索火星的多种动机，如“探索独特环境的渴望”“成为开拓者的兴奋”“科学家的研究可能带来成就”等，原文明确提到“Here are the things you can think of…”并分点说明，直接表明去火星存在许多理由。故选B项。 【46题详解】 推理判断题。由第三段中“when people finally realize that tow-way trips to the red planet Mars are unnecessary (当人们最终意识到前往红色星球火星的双向旅行是不必要的时)”和“Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world. (因此，减少回家的行程将减少事故的危险，节省大量资金，并为在另一个世界建立永久的人类定居点开辟道路)”可知，Paul Davies认为前往红色星球火星的双向旅行是不必要的，且减少回家的行程有好处，可得出他认为人类只需要一张去火星的单程票。故选A项。 【47题详解】 细节理解题。由最后一段中“Mars has all the materials for a colony to produce or make everything it needs, and Mars is far more pleasant than the other planets in the outer space. (火星拥有殖民地生产或制造所需一切的所有材料，火星比外太空的其他行星更令人愉快)”可知，人类可以在火星上生产他们需要的一切。故选C项。 D PEOPLE who have had a painful experience may wish they could wipe the memory from their minds. Researchers at Johns Hopkins University, US, say that this may someday be possible. A drug remains far off, but researchers have laid a foundation with their discovery that proteins can be removed from the brain’s fear center to cut memories forever. Previous research had already shown that a special behavior therapy (治疗) could cut painful memories. But relapse (复发) was possible because the memory hadn’t necessarily disappeared. By looking at that process, Richard Huganir and Roger Clem, two researchers from Johns Hopkins University, discovered a “window of vulnerability (脆弱的窗口)” when proteins are created. The proteins help signals travel within the brain as painful memories are made. Because the proteins are unstable, they can be easily removed with drugs or behavior therapy to cut memories. Researchers used mice to find the window, but think the process would be the same in humans. They used electric shocks to make the mice fear a certain sound. The sound triggered (触发) the creation of the proteins, called calcium-permeable (钙通透性) AMPARS, which formed for a day or two in the fear centers of the mice’s brains. The researchers are working on ways to reopen the window by recalling (唤醒) the painful memory and using drugs to remove the protein. They published their report online last month in Science Express. Their research has drawn interest and concern from experts in mental healthcare. Kate Farinholt, a mental health expert with the National Alliance on Mental Illness, Maryland, US, said many people suffering from a painful event might benefit from erasing a memory. “Erasing a memory and then everything bad built on that is an amazing idea, and I can see all sorts of potential,” she said. But there are a lot of unanswered questions, too. “Completely deleting a memory is a little scary. How do you remove a memory without removing a part of someone’s life,” Farinholt said. “And is it best to do that, considering that people grow and learn from their experiences?” 48. What have researchers at Johns Hopkins University found recently? A. A new drug to erase painful memories from human brains. B. A special behavior therapy to erase painful memories. C. Removing certain proteins from the brain can wipe painful memories. D. Erasing memory damages a patient’s brain functions. 49. What makes it possible to erase painful memories according to Paragraph 4? A. The way the brain cells are created. B. The unstable character of the proteins in the brain. C. The strength of the signals the proteins send. D. The drugs that can stop the formation of memories. 50. Which of the following shows the stages of the process done on mice? a. removal of fear proteins b. making mice fear a certain sound c. fear proteins created in mice brains d. making mice recall painful memories A. a-b-c-d B. d-a-c-b C. b-c-d-a D. c-b-d-a 51. What is Kate Farinholt’s opinion of the research? A. People may lose the chance to learn from their bad experiences. B. The research will be a great breakthrough in treating painful memories. C. People could suffer long-term memory loss. D. People could forget happy memories as well. 【答案】48. C 49. B 50. C 51. A 【解析】 【导语】本文是一篇说明文。文章主要讲述了约翰霍普金斯大学研究发现移除大脑中的某些蛋白质可消除痛苦记忆。 【48题详解】 细节理解题。根据第二段“A drug remains far off, but researchers have laid a foundation with their discovery that proteins can be removed from the brain’s fear center to cut memories forever. (一种药物仍然遥遥无期，但研究人员已经奠定了基础，他们发现可以从大脑的恐惧中心移除蛋白质，从而永远消除记忆)”可知，约翰霍普金斯大学的研究人员最近发现，从大脑中移除某些蛋白质可以消除痛苦的记忆。故选C。 【49题详解】 细节理解题。根据第四段中“Because the proteins are unstable, they can be easily removed with drugs or behavior therapy to cut memories. (因为这些蛋白质不稳定，所以它们很容易被药物或行为疗法去除，从而消除记忆)”可知，大脑中蛋白质的不稳定性使得消除痛苦记忆成为可能。故选B。 【50题详解】 细节理解题。根据第五段中“They used electric shocks to make the mice fear a certain sound. The sound triggered (触发) the creation of the proteins, called calcium-permeable (钙通透性) AMPARS, which formed for a day or two in the fear centers of the mice’s brains. (他们用电击的方式让老鼠对某种声音产生恐惧。这种声音触发了一种名为钙通透性 α- 氨基 - 3 - 羟基 - 5 - 甲基 - 4 - 异恶唑丙酸受体（AMPARS）的蛋白质的产生，这些蛋白质在老鼠大脑的恐惧中枢中会持续形成一两天。)”以及第六段中“The researchers are working on ways to reopen the window by recalling (唤醒) the painful memory and using drugs to remove the protein. (研究人员正在研究通过回忆痛苦的记忆和使用药物去除蛋白质来重新打开这个窗口的方法。)”可知，对老鼠进行的实验过程为：先让老鼠害怕某种声音，然后老鼠大脑中产生恐惧蛋白，接着让老鼠回忆痛苦的记忆，最后去除恐惧蛋白。因此，正确的顺序是b-c-d-a。故选C。 【51题详解】 推理判断题。根据最后一段““Completely deleting a memory is a little scary. How do you remove a memory without removing a part of someone’s life,” Farinholt said. “And is it best to do that, considering that people grow and learn from their experiences?” (“完全删除一段记忆有点可怕。你要如何在不抹去一个人生活的一部分的情况下消除一段记忆呢？”Farinholt说，“而且考虑到人们是从自身经历中成长和学习的，这样做真的是最好的选择吗？”)”可知，Kate Farinholt认为这样做人们可能会失去从糟糕的经历中吸取教训的机会。故选A。 E Ok, I admit it: Emoticons (表情符号) are popular. Some people even think they are fun. Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications. Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast the use of emotions as “infantile (幼稚的) just like the people who use them”. He believes that words themselves should be enough. “If you’re being funny, happy or sad, that should be apparent from the comment that goes before the emoticons,” he argues. In the eyes of Blumenthal, the use of emoticons is a gender issue. “Men don’t use emoticons very much. Maybe not at all,” he said. “Teenage girls and women seem to use them a lot. Maybe there’s an emoticons gene.” It’s an interesting opinion, but it is not shared by all. In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed “to seek out representations of humanity”. He believes that they appeal not because they are shortcuts for the lazy, but because they tap into (输入) something beyond language. They reach to our need to be with and communicate with people. All of these arguments may be somehow valid (正确的). Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking. Friends, however, send me messages and e-mails full of emoticons. I have no problem with this, I don’t regard any of my friends as lazy or immature. It’s just a question of individuality. 52. According to the article, emoticons are popular because ________. A most of them look funny B. they are easy for lazy people to use C. they add feeling and character to a communication D. a reader cannot understand a message without them 53. Which of the following views would John Blumenthal agree with? A. Instant Message chatters are childish. B. It’s enough to use language in digital communication. C. Men never use emoticons. D. There is an emoticon gene in everybody. 54. From the text, we can conclude that the author ________. A. feels he has no difficulty using emoticons B. thinks emoticons don’t suit him C. encourage his friends to use emoticons D. believes that emoticons are suitable for everyone 55. What is the main point of the article ? A. Advice on language used over the Internet. B. The history of emoticons. C. Arguments over the use of emoticons. D. Reasons for the popularity of emoticons. 【答案】52. C 53. B 54. B 55. C 【解析】 【导语】本文是一篇议论文，主要讨论了表情符号的流行以及不同人对使用表情符号的不同观点。 【52题详解】 细节理解题。根据文章第一段“Some feel that they add feeling and character to otherwise cold digital communications.(有些人觉得它们为冷冰冰的数字交流增添了感情和个性。)”可知，表情符号因能增强交流的情感和个性而受欢迎。故选C。 【53题详解】 细节理解题。根据文章第二段“Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast the use of emotions as “infantile (幼稚的) just like the people who use them”. He believes that words themselves should be enough. (然而，编辑兼好莱坞编剧John Blumenthal等人则抨击情感的使用是‘幼稚的，就像使用它们的人一样’。他认为文字本身就足够了)”可知，John Blumenthal认为在数字交流中仅用语言就足够了。故选B。 【54题详解】 推理判断题。根据文章倒数第二段中“I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking.(我可没那么多时间看表情符号。我曾经试着用过一次，感觉就像我偷偷溜进了一个没有我位置的小学班级。我宁愿用我的文字来说话。)”可推知，作者认为表情符号不适合自己。故选B。 【55题详解】 主旨大意题。根据第一段“Ok, I admit it: Emoticons (表情符号) are popular. Some people even think they are fun. Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications.(好吧，我承认：表情符号很受欢迎。有些人甚至认为它们很有趣。许多人似乎无法在电子邮件或即时消息聊天中不使用表情符号。有人觉得它们为原本冷冰冰的数字交流增添了情感和个性。)”、第二段“Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast the use of emotions as “infantile (幼稚的) just like the people who use them”. (然而，编辑兼好莱坞编剧John Blumenthal等人则抨击情感的使用是‘幼稚的，就像使用它们的人一样’。)”并结合全文内容可知，文章围绕使用表情符号的争议展开，分别呈现了反对者（如Blumenthal）、支持者（如Keltner）和作者的观点，选项C“关于表情符号使用的争论”准确概括了主旨。故选C。 第二卷（非选择题,共35分） 第一节 短文改错（共10小题;每小题1分,满分10分） 短文改错 I was recent told that listening to loud music is gradually ___56___ making people lose hearing.

I am writing to tell you about some symptoms of anxiety among us students before exams. Most of us feel nervous whenever we’re taking an important exam. Some will feel dizzy or tired, some will suffer from lack of sleep, and some will lose their appetite. In fact, all these symptoms have terrible effects on our exams and we are all eager to get rid of them. First of all, it’s important for us to have a fight attitude towards exams. They are only a means of checking how we are getting along with our studies, so there is no need to worry too much about the results. Study hard every day and make careful plans for every exam. In this way we can avoid suffering from the pressure of exams. Besides, enough sleep can make us energetic and enable us to perform well in an exam. Therefore, during the period of exams, we should not stay up too late. We can also try a warm bath or a cup of warm milk before going to bed. They might help us to have a sound sleep. From my experience, going out for a walk or taking some outdoor exercise before going to bed can also keep ourselves relaxed. 【解析】 【导语】这是一篇应用文。考生发现部分同学每次遇到重要考试，都会出现一些焦虑症状。请你用英语写一封信，向某学生英文报编辑反映该问题并提出建议。 详解】1.词汇积累： 焦虑：anxiety→nervousness 摆脱：get rid of→rid oneself of 态度：attitude→manner 避免：avoid→escape 2.句式拓展： 同义句 原句：In this way we can avoid suffering from the pressure of exams. 拓展句：Only in this way can we avoid suffering from the pressure of exams. 【点睛】【高分句型 1】Most of us feel nervous whenever we’re taking an important exam.（运用了whenever引导的时间状语从句 ） 【高分句型 2】They are only a means of checking how we are getting along with our studies, so there is no need to worry too much about the results.（运用了 how 引导的宾语从句 ） 第1页/共1页 学科网（北京）股份有限公司 $$ 成都石室中学2025届高三一诊模拟试卷 第一卷 第二部分 英语知识运用（共两节，满分45分） 第一节 单项填空（共15小题；每小题l分，满分l5分） 1.

Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn’t have to be the outcome. Water shortages do not have to trouble the world — if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy. 36. What is the real cause of the potentials water crisis. A. Only half of the world’s water can be used. B. The world population is increasing faster and faster. C. Half of the world’s water resources have been seriously polluted. D. Humanity has not placed enough value on water resources. 37. As is indicated in the passage, the water problem _________ . A. is already serious in certain parts of the world. B. has been exaggerated by some experts in the field C. poses a challenge to the technology of building reservoirs (水库) D. is underestimated by government organizations at different levels 38. According to the author, the water price should _______ . A. be reduced to the minimum B. stimulate domestic demand C go with its real value D. take into account the occurrences of droughts 39. In order to raise the efficiency of the water supply, measures should be taken to ______ . A. guarantee full protection of the environment B. centralize the management of water resources C. increase the sense of responsibility of agencies at all levels D. encourage local and regional water resources B Federal regulators(调整者) Wednesday approved a plan to create a nationwide emergence alert (警报) system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates（估计） more than 48 billion text messages are sent each month. The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation’s emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers –telecommunications companies is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three different types of messages, according to the rules. The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架) emergencies, or so-called Amber Alerts. The service could be in place by 2010. 40. What is the purpose of the approved plan? A. To warn people of emergencies via messages. B. To popularize the use of cell phones. C. To estimate the monthly number of messages. D. To promote the wireless industry. 41. The improvement to the present system is in the charge of ____. A. CTIA B. the Warning Alert and Response Network C. FCC D. federal regulators 42. The carriers’ participation in the system is determined by _____. A the US federal government B. mobile phone users C. the carriers themselves D. the law of the United States 43. Which of the following would be the best title for the text? A. Cell Phone Alerts Protecting Students B. Cell Phone Alerts by Wireless Industry C. Cell Phone Alerts of National Disasters D. Cell Phone Alerts Coming Soon C While all my classmates seen to be crazy about a one-way ticket to Mars (火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return? Steve Minear, UK Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory… For scientists there is another reason. Their observations and research will probably lead to great scientific achievements. Donal Trollop, Canada There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony (殖民地) on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches (发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world. Enough supplies can be sent on ahead, and every two years more supplies and more people will be sent to the new colony. Mars has all the materials for a colony to produce or make everything it needs, and Mars is far more pleasant than the other planets in the outer space. Paul Davies, USA 44. The main purpose of Steve Minear’s writing is . A. to report his classmates’ discussion B. to invite an answer to his question C. to explain the natural state of Mars D. to show his agreement on going to Mars 45. Which of the following best states Donal Trollop’s idea? A. There is a plan to send humans to Mars. B. There are many reasons for going to Mars. C. Scientists become famous by doing research on Mars. D. It is possible to build an Earth-like environment on Mars. 46. Paul Davies points out that . A. humans need only a one-way ticket to Mars B. two-way trips to Mars will be made safe soon C. it is easy to reduce the danger and cost of flights to Mars D. it is cheap to build an everlasting human settlement on Mars 47. What does Paul Davies think of human existence on Mars? A. Humans will have to bring all they need from the Earth. B. Humans will find Mars totally unsuitable for living. C. Humans can produce everything they need. D. Humans can live longer in the colony on Mars. D PEOPLE who have had a painful experience may wish they could wipe the memory from their minds. Researchers at Johns Hopkins University, US, say that this may someday be possible. A drug remains far off, but researchers have laid a foundation with their discovery that proteins can be removed from the brain’s fear center to cut memories forever. Previous research had already shown that a special behavior therapy (治疗) could cut painful memories. But relapse (复发) was possible because the memory hadn’t necessarily disappeared. By looking at that process, Richard Huganir and Roger Clem, two researchers from Johns Hopkins University, discovered a “window of vulnerability (脆弱的窗口)” when proteins are created. The proteins help signals travel within the brain as painful memories are made. Because the proteins are unstable, they can be easily removed with drugs or behavior therapy to cut memories. Researchers used mice to find the window, but think the process would be the same in humans. They used electric shocks to make the mice fear a certain sound. The sound triggered (触发) the creation of the proteins, called calcium-permeable (钙通透性) AMPARS, which formed for a day or two in the fear centers of the mice’s brains. The researchers are working on ways to reopen the window by recalling (唤醒) the painful memory and using drugs to remove the protein. They published their report online last month in Science Express. Their research has drawn interest and concern from experts in mental healthcare. Kate Farinholt, a mental health expert with the National Alliance on Mental Illness, Maryland, US, said many people suffering from a painful event might benefit from erasing a memory. “Erasing a memory and then everything bad built on that is an amazing idea, and I can see all sorts of potential,” she said. But there are a lot of unanswered questions, too. “Completely deleting a memory is a little scary. How do you remove a memory without removing a part of someone’s life,” Farinholt said. “And is it best to do that, considering that people grow and learn from their experiences?” 48. What have researchers at Johns Hopkins University found recently? A. A new drug to erase painful memories from human brains. B. A special behavior therapy to erase painful memories. C. Removing certain proteins from the brain can wipe painful memories. D. Erasing memory damages a patient’s brain functions. 49. What makes it possible to erase painful memories according to Paragraph 4? A. The way the brain cells are created. B. The unstable character of the proteins in the brain. C.

Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications. Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast the use of emotions as “infantile (幼稚的) just like the people who use them”. He believes that words themselves should be enough. “If you’re being funny, happy or sad, that should be apparent from the comment that goes before the emoticons,” he argues. In the eyes of Blumenthal, the use of emoticons is a gender issue. “Men don’t use emoticons very much. Maybe not at all,” he said. “Teenage girls and women seem to use them a lot. Maybe there’s an emoticons gene.” It’s an interesting opinion, but it is not shared by all. In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed “to seek out representations of humanity”. He believes that they appeal not because they are shortcuts for the lazy, but because they tap into (输入) something beyond language. They reach to our need to be with and communicate with people. All of these arguments may be somehow valid (正确的). Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking. Friends, however, send me messages and e-mails full of emoticons. I have no problem with this, I don’t regard any of my friends as lazy or immature. It’s just a question of individuality. 52.
