（2020全国卷I ）话题：植物新科技
D
The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
The engineers at the Massachusetts Institute of Technology（MIT）have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show whe n they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.
One of his latest projects has been to make plants grow（发光）in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.
in the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.
Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source（电源）—such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission（传输）.
Glowing plants could reduce this distance and therefore help save energy.
32. What is the first paragraph mainly about?
A. A new study of different plants.
B. A big fall in crime rates.
C. Employees from various workplaces.
D. Benefits from green plants.
33. What is the function of the sensors printed on plant leaves by MIT engineer?

D. How are glowing plants made pollution-free?
（2019全国卷I ）话题：利用生物信息进行身份识别
C
As data and identity theft becomes more and more common, the market is growing for biometric（生物测量）technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device（装置）that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence （节奏）with which one types and the pressure fingers apply to each key. The keyboard could
offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to —regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word ＂touch＂four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
28. Why do the researchers develop the smart keyboard?
A. To reduce pressure on keys.
B. To improve accuracy in typing
C. To replace the password system.
D. To cut the cost of e-space protection.
29. What makes the invention of the smart keyboard possible?
A. Computers are much easier to operate.
B. Fingerprint scanning techniques develop fast.
C. Typing patterns vary from person to person.
D. Data security measures are guaranteed.
30. What do the researchers expect of the smart keyboard?
A. It’ll be environment-friendly.
B. It’ll reach consumers soon.
C. It’ll be made of plastics.
D. It’ll help speed up typing.
31. Where is this text most likely from?
A. A diary.
B. A guidebook
C. A novel.
D. A magazine.
（2018全国卷I）话题：不同电器设备耗电研究
D
We may think we’re a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn’t throw out our old ones. “The living-room television is replaced and gets planted in the kids’ room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We’re not just keeping these old devices – we continue to use them. According to the analysis of Babbitt’s team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.
So what’s the solution (解决方案)? The team’s data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
32. What does the author think of new devices?
A. They are environment-friendly.
B. They are no better than the old.
C. They cost more to use at home.
D. They go out of style quickly.
33. Why did Babbitt’s team conduct the research?
A. To reduce the cost of minerals.
B. To test the life cycle of a product.
C. To update consumers on new technology.
D. To find out electricity consumption of the devices.
34. Which of the following uses the least energy?
A. The box-set TV.
B. The tablet.
C. The LCD TV.
D. The desktop computer.
35. What does the text suggest people do about old electronic devices?
A. Stop using them.
B. Take them apart.
C. Upgrade them.
D. Recycle them.
(2020全国卷II) 话题：海狸鼠毛皮的利用问题
C
When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装）enthusiasts are trying
to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have（showcased）nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”,says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species（物种）.It’s destroying the environment. It’s them or us." says Michael Massimi, an expert in this field.
The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He s ays it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Morgan says，“To give people a guilt-free option that they can wear without someone throwing paint on them—1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a lable to attach to nutria fashions to show it is eco-friendly.
28. What is the purpose of the fashion shows in New Orleans and Brooklyn?
A. To promote guilt-free fur.
B. To expand the fashion market.
C. To introduce a new brand.
D. To celebrate a winter holiday.
29. Why are scientists concerned about nutria?
A. Nutria damage the ecosystem seriously.
B. Nutria are an endangered species.
C. Nutria hurt local cat-sized animals.
D. Nutria are illegally hunted.
30. What does the underlined word “collapsed” in paragraph 5 probably mean?
A. Boomed.
B. Became mature.
C. Remained stable.
D. Crashed.
31. What can we infer abouf wearing fur in New York according to Morgan?
A. It’s formal.
B. It’s risky.
C. It’s harmful.
D. It’s traditional.
（2017全国卷I）话题：户外自制蒸馏器
D
A buld-it-yourself solar still（蒸馏器）is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5＇ 5＇sheet of clear or slightly milky plastic, six feet of plastic tube, and a container—perhaps just a drinking cup —to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.
To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up —and out —the side of the hole.
Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.
The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment zxxk out through the tube, and won’t have to break down the still every time you need a drink.
32. What do we know about the solar still equipment from the first paragraph?
A. It’s delicate.
B. It’s expensive.
C. It’s complex.
D. It’s portable.
33. What does the underlined phrase “the water catcher” in paragraph 2 refer to?
A. The tube.
B. The still.
C. The hole.
D. The cup.
34. What’s the last step of constructing a working solar still?
A. Dig a hole of a certain size.
B. Put the cup in place.
C. Weight the sheet’s center down.
D. Cover the hole with the plastic sheet.
35. When a solar still works, drops of water come into the cup form .
A. the plastic tube
B. outside the hole
C. the open air
D. beneath the sheet
（2016全国卷I）话题: 不同文化背景下的沉默内涵
The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say.
A silence in a conversation may also show stubbornness, or worry. Silen ce may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap
with conversation. Persons in other cultural groups value silence and vie w it as necessary for understanding a person's needs.
Many Native Americans value silence and feel it is a basic part of co mmunicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is spea king and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in
authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.
Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient’s silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.
32.What does the author say about silence in conversations?
A.It implies anger.
B.It promotes friendship.
C.It is culture-specific.
D.It is content-based.
33.Which of the following people might regard silence as a call for careful thought?
A.The Chinese.
B.The French.
C.The Mexicans.
D.The Russians.
34.What does the author advise nurses to do about silence?
A.Let it continue as the patient pleases.
B.Break it while treating patients.
C.Evaluate its harm to patients.
D.Make use of its healing effects.
35.What may be the best title for the text?
A.Sound and Silence
B.What It Means to Be Silent
C.Silence to Native Americans
D.Speech Is Silver; Silence Is Gold

初中中考语文说明文阅读专题训练训练试题及解析 一、中考语文说明文阅读专题训练 1．阅读下文，完成下列小题。 鳖鱼是海洋系统的“整容师” ①鳖鱼是海洋中的庞然大物，也是食肉类的凶猛鱼类，号称“海中狼”。可是，最近它被贴上了“整容师”的标签，因为它可以改变海洋中很多鱼的眼睛和尾鳍的尺寸。听到这些，你是否感到十分惊讶呢？ ②原来，在海洋系统中，许多小鱼都有着较大的眼睛和有力的尾鳍，帮助它们及时发现并快速躲避鲨鱼的攻击和吞食。尤其在鲨鱼出没捕食的低光环镜下更加如此：一定尺寸的尾鳍可以保证鱼类突然加速游动，以此来远离鲨鱼的追捕。但是，在2018年1月，西澳大利亚大学等研究机构人员的最新研究发现，近年来由于人类对鲨鱼的大量捕杀，导致多种鲨鱼濒临灭绝。鲨鱼数量的减少，使得其他鱼类的生存得到了暂时的和平安稳，导致它们的形态也正在发生明显的改变，如：眼睛变小，尾鳍变小。因此，鲨鱼就成了海洋系统里的“整容师”。 ③研究人员对澳大利亚西北海域罗利沙洲和斯科特礁两个珊瑚礁系统中7种不同的鱼类专门进行了对比分析。这两个珊瑚礁有着相似的自然环境，但不同的是，罗利沙洲禁止捕鱼，鲨鱼数量比较稳定，而斯科特礁允许对鲨鱼进行商业捕捞，且已经持续了一百多年。研究人员分别在两个珊瑚礁海域进行了采样捕捞，并测量出了所捕捞鱼的体长、体宽、眼部和尾鳍大小。结果发现，与罗沙洲的鱼类相比，斯科特礁同种鱼类的眼睛尺寸小46%，尾尺寸小4%。 ④研究人员解释说，人类捕捞鲨鱼使其数量减少，会造成一系列生态后果，小鱼的眼睛及尾鳍尺寸等发生变化仅仅是一个方面，其实，鲨鱼数量的减少还在悄悄地影响着其他海洋生态系统。 ⑤首先，鲨鱼数量的大幅度减少，那些体弱多病，基因突变导致畸形的鱼，就不会及时被消灭，进化过程中的优胜劣汰也不能更好地延续下去。那些没有被吃掉的弱鱼，病鱼就会一直繁殖下去，直到基因退化，这不利于种群的健康发展，对整个海洋生物多样性，优化性将是一个致命打击。 ⑥其次，鲨鱼数量的大幅度减少，将使海洋生态环境无法正常维持，水质环境会进一步恶化。因为，鲨鱼是海洋系统名副其实的“清道夫”。它可以通过清理腐烂的大型海洋动物尸体，来净化海洋生态环境。 ⑦由此看来，鲨鱼在保持海洋生态系统平衡中扮演了至关重要的角色，称它为海洋系统的“整容师”一点儿也不过分。 （1）鲨鱼在保持海洋生态系统平衡中发挥了哪些方面的作用？ （2）有文章第③段中画线句子除了列数字以外，还运用了哪种说明方法？有何作用？（3）“其实，鲨鱼数量的减少还在悄悄地影响着其他海洋生态系统。”为什么用“悄悄”一词？ 【答案】（1）①可以改变海洋中鱼的眼睛和尾鳍的大小。②维护海洋生态平衡，有利于种群的健康发展。③净化海洋生态环境，改善水质。 （2）作比较。通过斯科特礁鱼类和罗利沙洲鱼类的比较，准确地说明了鲨鱼对海洋中许多
阅读理解训练50篇（1） 1 Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer. Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell.But other people keep their anger inside. They can not or will not express it. This is called repressing anger. For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hor- mones (荷尔蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etC．In general the person feels excited and ready to act. Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure. Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.” Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. They said that laughter is much healthier than anger. 1．“Damaging emotion” means t hat _________. A．the emotion is harmless B．the emotion is harmful C．the feeling is very strong D．the feeling is hard 2．What statement is right? A．Were you angry, you would be cancered (得癌症). B．Once you are angry, you must be cancered. C．Angry as you are often, you can't be cancered, D．Anger may cause you a cancer. 3．Expressing anger violently _________ repressing it according to some scientists. A．is just the same as B．is more harmful than C．is no better than D．is much better than 4．According to the author, you'd better _________. A．never be angry B．cool it down before you express it C．laugh and laugh when you get angry D．admit you are wrong when you are angry 二
高考英语阅读理解专项训练100篇 (名师传授解题技巧+实战练习，值得下载) 一、阅读理解解题技巧 阅读理解题是考查学生对活的语言材料的理解能力，即通过阅读材料获得信息的能力。具体说来，阅读理解能力测试的主要要求是：（1）掌握所读材料的主旨大意，以及用以说明主旨大意的事实和细节；（2）既理解具体事实，也理解抽象的概念；（3）既理解字面意思，也理解深层含义，包括作者的态度、意图等；（4）既理解某句、某段的意义，也理解全篇的逻辑关系，并能根据文章进行推理和判断；（5）既能根据材料所提供的信息去理解，也能结合中学生应有的常识去理解。根据这几项能力测试的要求，试题中常采用如下几种题型：事实询问题、推理判断题、数据推算题、识图解意题和主旨大意题。根据这一测试要求和题型设计，答题时可以采取如下解题技巧和对策。 1．首先解题时要充满自信。由于平时有些同学对做阅读理解时存在一种畏惧心理，因此考试做题时心理就难免会产生紧张感，特别是阅读时再遇到几个生词就头脑发胀，从而使自己的思路更加模糊不清。其实这是完全没有必要的，因为阅读中遇到几个生词或几个难以理解的句子是常有的事，也是正常现象。因为按大纲要求，试卷中允许有不超过3%的生词，只要认真分析，仔细阅读，这些生词和句子很可能并不影响你的解题。所以答题之前首先要有必胜的信心。 2．扫读全文，理解全文主旨大意。拿到一篇文章，首先要快速扫读全文，虽为扫读，但不可漫不经心，阅读时也应聚精会神，力求可能多地获取材料信息，只是这次遇到生词和难句先不必去处理，不要因纠缠文中的个别生词和难句而影响了对全文的主旨大意的了解。
3．对症下药，各个击破。了解全文的大概意思之后，再把短文的问题简单看一遍，弄懂题意，然后带着问题再去寻读全文。这次阅读过程中要善于抓文章中的关键词句。寻读也就是迅速的查找需要了解的信息，是为某些特定的问题而阅读，因此阅读时要有较强的针对性，对与问题有关的数据，词句等仔细阅读，认真理解，同时结合不同考查内容的题型，采取如下解题对策： （1）事实询问题：这类试题通常是以疑问词what，who，when，where，why，how 等引起的特殊问句，就文章中某一词语、某一句子、某一段落或某一具体细节和事实进行提问。解答此类试题首先要弄清题目和每一个选项的含义，然后按题目要求寻找与之相关的细节，正确估计答案来源，同时注意题目和文章中的暗示作用。特别注意辨别各种信息，确认各种信息。 （2）推理判断题：此题要求我们通过表面文字信息去推测文章隐含的意思，对文章的发展情节及作者的态度、意图等做出合乎逻辑的的推理判断。这种题要求我们在阅读时要抓住文章的主题和细节、从分析文章的结构入手，根据上下文的内在联系，充分挖掘文章的深层含义。对暗含在文章中事件的因果关系，人物的动机，以及作者未言明的倾向、态度、意图、观点进行合乎逻辑的推理、分析和判断。同时善于抓住文中实质性的东西，不要被带假象的表面信息或似是而非的东西所迷惑。并且注意推断作者态度时要力求从作者的态度、观点去思考，切勿想当然，凭个人的观点习惯看法来回答的问题。 （3）数据推算题：此题要求我们就文章提供的数据，以及数据与文章中其他信息的关系做出计算和推断，然后做出选择。这就要求我们解题时，要在理解好题意的前提下去对与数据有关的信息认真分析，若数据信息较多，还要注意弄清数据之间的关系，同时分清有用与无用信息，最终作出正确判断。 （4）主旨大意题：此题用以考查我们对文章主题或中心思想的领会和理解能力。在解答此类试题时要注意每段的中心句，抓住每一段的主题句。一般主题句都用来表达一段主旨大意，因此，只要找准每段的主题句，文章的中心思想和文章的最佳标题也就不难确定了。

高考英语阅读理解专项训练及答案及解析 一、高中英语阅读理解 1．阅读理解 Traditional Chinese medicine (TCM) is gaining global popularity. According to a government white paper, TCM has been introduced in 183 countries and regions around the world. Westerners' understanding of TCM, however, may be limited to acupuncture, cupping and massage(针灸，拔罐和按摩). For instance, the purple, injury-like marks left on U. S. swimmer Michael Phelps，back from cupping for the purpose of relaxing his muscles and reducing pain became the center of attention during the Rio Olympics in 2016. As a matter of fact, Chinese herbs play a more important role in getting rid of diseases and keeping the body in good condition in the TCM treatment system than physical treatment. It is therefore disheartening to know that while 103 World Health Organization member countries have given approval to the practice of acupuncture, not many recognize Chinese herbal medicine. TCM falls far behind Western medicine owing partly to the slow development of Chinese herbs. Herbs are made into pills, powder and soup, and the kind of herbs used, their quality and quantity, and the processing of the ingredients (原材料) jointly determine the effectiveness of the prescription. Compared with Western medicine, which has standardized drug production processes and treatment methods, TCM lacks standardization, with the chemical composition and functions of its medicines being unclear and their effects being unstable. Fortunately, standardization has improved in recent decades, with an increasing number of factories producing patented TCM drugs. Another factor that has prevented the development of TCM prescription drugs is the lack of creativity. While Western medicine-making companies come up with new products every year, TCM drug producers tend to make medicines according to prescriptions handed down from the past. Chinese chemist Tu Youyou's winning the 2015 Nobel Prize in Physiology or Medicine for her research into malaria (疟疾) treatment may drive creativity to some extent in China's TCM industry. However, the current state of affairs cannot be changed within a short time. （1）Why does the author mention the example of Michael Phelps? A. Because he was injured in his swimming. B. Because cupping is a kind of important TCM treatment. C. Because westerners know a little about TCM. D. Because westerners attach great importance to TCM. （2）Why don't some member countries of WHO recognize Chinese herbal medicine? A. Because Chinese herbs can get rid of diseases. B. Because they only approve the practice of acupuncture. C. Because Western medicine is more effective. D. Because medicine made out of Chinese herbs develops slowly. （3）Compared with Western medicine, what is the weak point of TCM in Paragraph 4? A. The methods of planting herbs. B. The effectiveness of prescription. C. Lacking in standardization. D. Its stable functions.

There were five girls who were members of the Danville High School basketball team—all of them starters. They were not in uniform to play that night and would not be on the team for the rest of this season. They were there to admit their breaking of team rules. They were there to support their coach's decision to take them off the team. They were there to let the town know there was a problem in their little community that needed to be addressed. And they did it with sincere regret rather than defensiveness. While the school had been out for the New Year's holiday, the five girls had gone to the party with several of their friends. There was alcohol there. And they all drank some. Coach Rainville has a zero tolerance rule on drugs and alcohol for her members though it was a hard decision to make. When classes resumed and accounts of holiday parties were shared, rumors about the five girls began closing in on them. The coach said she couldn't back down on her rules. And the players—two junior students and three senior students—agreed. That night in the gym was part of their public support of the coach's decision. “We hope you will understand that we are not bad kids. What we did was definitely not worth it. We hope this event will make everyone realize that there is a big drug and alcohol problem in our community,” one of the senior students said, “And if you work with us to try to solve this problem, you will help us feel that we have not been thrown off our basketball team for nothing.” The five left the floor to deafening applause. The team may not win another game this year. But they've learnt something about personal responsibility, the effect of one's action on others, and honesty that will serve them well throughout life. （1）It can be inferred from the passage that the five girls who were kicked off the team were ________. A. very good players on the team B. addicted to alcohol and drugs C. three junior students and two senior students D. scolded by their parents for drinking alcohol （2）What did the girls do to support their coach's decision? A. They didn't fight for Danville High School any more. B. They all gave speeches to apologize in the local press. C. They admitted their mistake in public in the gymnasium. D. They would never drink any alcohol throughout their life. （3）Which word best describes the coach Rainville? A. Indifferent. B. Strict. C. Stubborn. D. Cruel. （4）Which would be the best title for the passage? A. Growing up with pain B. A bad mistake C. Team rules are everything D. Basketball girls in high school 【答案】（1）A

For her drive and creativity in overcoming those challenges,she’s been named national teacher of the year. Principal Waynes Kettler said he’s worked with many outstanding teachers in his22years as an educator,but Peterson is“just that one step above anybody I’ve ever worked with before.” Kettler and others at Monte Cristo Elementary School talk about the ways she has introduced the learning from other classrooms into her music program and her creativity in working around things such as the lack of money for new music. When students were reading S.E.Hinton’s novel The Outsiders in their regular classroom, Peterson helped them write a30-minute play with scenes from the book.Then they chose three Broadway tunes that focused no race,equality and social justice,the themes of the book.Peterson composed two other songs herself after classroom discussions about the play and the book. The honor means a lot to residents of Granite Foils.It’s inspiring to know that people from small towns own even win national honors. As national teacher of the year,Peterson will spend the next year outside the classroom, as a national and international spokeswoman for education. Not surprisingly,She is a big believe in the value of arts education.She said it’s essential for schools to offer classes such as art or music and physical education because for some kids one of those subjects is the only thing that motivates them to come back to school day after day. 65.The underlined word“daunting”in Paragraph1most probably means__________. A. discouraging B.interesting C.creative D.unbearable
植物也唱《好汉歌》 ◇力夫 ①以描写行侠仗义的英雄好汉著称的我国四大名著之一《水浒传》被改编成电视连续剧播出以后，它的主题歌——《好汉歌》因简洁、生动地颂扬了好汉精神而立即流传开来：“大河向东流/天上的星星参北斗哇/生死之交一碗酒啊/说走咱就走/你有我有全都有哇/水里火里不回头哇/路见不平一声吼啊/该出手时就出手/风风火火闯九州……” ②也许让你想象不到的是，不但是人们爱唱《好汉歌》，就连一些植物也爱唱《好汉歌》，只不过它们不是用歌喉“唱”，而是用自己的行动“唱”。不信，你仔细听—— ③植物懂得情感，有自己的喜怒哀乐，这已经被科学研究所证实。科学家通过细致的研究还发现，植物还有建立在情感基础之上的“价值观念”，如一些植物在行为中就体现出了明显的“仁爱”精神。 ④有一种原野灌木就“见利”而不忘“仁爱”。我们知道，灌木本身就是依靠扩展自己的庞大的根系来汲取水分的。但奇怪的是，当这种原野灌木的根部在土壤中深入或扩散时，快要到达“邻居”的根的地界后，便立即停止扩张。而且这种相遇并不是直接碰面，它们能够在一定的距离范围内相互识别出对方。连植物都懂得和平共处，相互尊重邻居的生存空间，不蓄意侵犯同伴的领地，这对那些为争夺领土而打打杀杀的人类来说无疑是一种嘲讽。 ⑤植物讲“仁爱”已经够稀奇了，但科学家还发现，一些植物还很讲“义气”。 ⑥如一些植物在受到侵害后，即使在“严重负伤”的情况下也不忘记给同伴发“遇险警戒”信号。中国农业大学昆虫学系教授高希武领导的课题组就发现了这个现象；他们将两株棉苗放入一个密闭玻璃容器，只对其中的一株棉苗进行啃食和机械损伤处理。在对两株棉苗和容器内的空气进行分析后，他们发现奇异现象：不但受伤的棉苗发生了防御反应，另一株没有受伤的棉苗也同样产生了防御反应。通过对植物受伤后24小时、48小时和72小时不同时间段的定量分析，他们发现，没有受伤的棉苗所产生的防御性化学物质浓度甚至高于受伤棉苗。类似的实验一共进行了三次，都验证了这一结果。这个现象表明，受伤的棉苗在抵御侵害的同时，并没有忘记“通知”同伴——“敌人来人”！ ⑦科学家还发现，植物们还相当“讲求公道”，不但敢于“鸣不平”，即便没有被逼上“绝路”也敢于为维护“公道”而“造反”。甚至在个人或同伴“权益”受到损害时，也敢于“拔刀相助”。 ⑧如土豆被人削皮时，它就会立即发出“抗议”的喊声，只是其音频人耳无法辨别罢了。如果你把西红柿的植株放在卧室里过夜，又忘了给它浇水，它就会用释放“清醒剂”的方式向你提出“抗议”，“警告”你不要再睡懒觉，快起来给它“喂水”。 ⑨科学家们认为，植物的一系列“好汉行为”不断被发现本身就说明以往人类对他们的认识还比较肤浅，包括植物与植物、植物与人类进行信息联络的通讯技术在内的许许多多未解之谜，都有待人们进一步去破解，人类对于植物情感世界的研究也还应该更深入、更广泛。 （选自《青少年科技博览》2010年12期） 1.“类似的实验一共进行了三次，都验证了这一结果”一句中黑体的“这一结果”指什么？ 2. 请简要概括，植物的“好汉行为”包括哪些现象？
高考英语阅读理解练习题及答案及解析 一、高中英语阅读理解 1．阅读理解 I was born on the 17th of November 1828, in the village of Nam Ping, which is about four miles southwest of the Portuguese Colony (殖民地) of Macao, and is located on Pedro Island lying west of Macao, from which it is separated by a channel of half a mile wide. As early as 1834, an English lady, Mrs. Gutzlaff, wife of a missionary to China, came to Macao. Supported by the Ladies' Association in London for the promotion of female education in India and the East, she immediately took up the work of starting a girls' school for Chinese girls, which was soon followed by the opening of a boys' school. Mrs. Gutzlaff's comprador(买办) happened to come from my village and was actually my father's friend and neighbor. It was through him that my parents heard about Mrs. Gutzlaff's school and it was doubtlessly through his influence and means that my father got me admitted into the school. It has always been a mystery to me why my parents should put me into a foreign school, instead of a traditional Confucian school, where my big brother was placed. Most certainly such a step would have been more suitable for Chinese public opinion, taste, and the wants of the country, than to allow me to attend an English school. Moreover, a Chinese belief is the only avenue in China that leads to political promotion, influence, power and wealth. I can only guess that as foreign communication with China was just beginning to grow, my parents hoped that it might be worthwhile to put one of their sons to learning English. In this way he might become an interpreter and have a more advantageous position to enter the business and diplomatic world. I am wondering if that influenced my parents to put me into Mrs. Gutzlaff's School. As to what other sequences it has eventually brought about in my later life, they were entirely left in the hands of God. （1）How was the author admitted to Mrs. Gutzlaff's school? A. Through his father's friend's help. B. Through his own efforts to exams. C. Through his father's request. D. Through Mrs. Gutzlaff's influence. （2）Why did the author's parents put him into an English school？ A. An English school was more influential. B. Foreign trade with China was developing fast. C. It met with Chinese public opinion. D. He could become a successful interpreter. （3）What did the author think of his parents' decision to put him into an English school? A. It was skeptical. B. It was mysterious. C. It was thoughtful. D. It was wonderful.【答案】（1）A （2）D （3）B 【解析】【分析】本文是一篇记叙文，小时候父亲送作者去英语学校而不是中文学校，并分析了具体原因。 （1）考查细节理解。根据第三段中的“Mrs. Gutzlaff's comprador(买办) happened to come from my village and was actually my father's friend and neighbor. It was through him that my parents heard about Mrs. Gutzlaff's school”可知，作者是通过父亲朋友的帮助进入到Mrs.
