2021届高考英语通用版一轮复习考点专讲：考点45阅读理解说明文学案

考点45 阅读理解说明文
高考频度：★★★★★

说明文是对事物或事理进行客观说明的一种文体，它以说明为主要表达方式，通过解说事物或阐明事理，达到教人以知识的目的，在结构上往往采用总分、递进等方式按一定的顺序（如时间、空间、从现象到本质）进行说明。说明文的特点是客观、简练、语言准确、明了，文章很少表达作者的感情倾向。阅读说明文的重点在于读懂它说明的事物或事理，了解事物的性质、构造、成因、功能等，了解事理的含意、特点等。最近五年，说明文的出现变化不大，一直很稳定，选材通常是各学科的前沿问题；高科技领域的科研成果；人们比较关心的社会问题；人文方面的经典。由于阅读理解题的设置采用渐进式，即由简到难的方式，因此说明文是高考试卷中阅读理解题中相对比较难的，通常后置。阅读理解试题的中要考点之一是考查学生对词汇和句式的掌握。说明文的词汇和句式的运用较别的体裁的文章难度更大。词汇运用灵活，同一词的不同词性的用法交替出现，未列入考纲的生词较多，通常达到了4-5%。不过考生可以通过说明文的语言特点来帮助理解语篇，例如，下定义、解释、举例、同义词、反义词、上下义词以及标点符号（如破折号、冒号都有表示解释和说明）等。
命题方式
考向一 细节理解题
说明文中考查的细节理解题大致与记叙文相似。命题区域都有其共同点：⑴在列举处命题，如用first(1y)、second(1y)、third(1y)finally、not only„but also、then、in addition等表示顺承关系的词语列举出事实。试题要求考生从列举出的内容中选出符合题干要求的答案项。⑵在例证处命题，句中常用由as、such as、for example、for instance等引导的短语或句子作为例证，这些例句或比喻就成为命题者设问的焦点。⑶在转折对比处命题，一般通过however、but、yet、in fact等词语来引导。对比用unlike、until、not so much…as等词语引导，命题者常对用来对比的双方属性进行考查。⑷在比较处命题，无端的比较、相反的比较、偷换对象的比较，经常出现在干扰项中，考生要标记并且关注到原文中的比较，才能顺利地排除干扰。⑸在复杂句中命题，包括同位词、插入语、定语、从句、不定式等，命题者主要考查考生对句子之间的指代关系和语法关系。  
细节类问题一般都能在原文中找到出处，只要仔细就可以在文中找到答案。但正确的选择项不可能与阅读材料的原文完全相同，而是用不同的语句成句型表达相同的意思。      
考向二 语意猜测题
 说明文为了把自然规律，事物的性质等介绍清楚或把事理阐述明白，因此学术性强的生词较多，所以常进行生词词义判断题的考查。命题方式多以the underlined part … in paragraph…refers to…或what does the underlined word mean?或what is the meaning of the underlined word?为设问方式。解题时考生应认真阅读原文，分析其对某些科学原理是如何定义、如何解释的，并以此为突破口抽象概括出生词词义。也可以通过上下文来猜测某个陌生词语的语意。或者找出某个词语在文章中的同义词。要注意破折号、同位语从句、定语从句、插入语等具有解释、说明作用的语言成分。说明文在阐述说明对象时易发生动作变换、人称转变的现象，这类题目常以it，they，them 等代词为命题点，因此考生要根据上下文语境，认真阅读原文，分析动作转换背景，弄清动作不同执行者，以便准确判断代词的其实际指代对象。      
考向三 主旨大意题
    说明文常用文章大意判断题考查考生对通篇文意的理解。即对文章的主题或中心意思的概括和归纳。主要考查考生对文章的整体理解能力。命题形式常以this passage mainly talks about ____. what is the main idea of the passage? 为设问方式。
答题时首先阅读题干，掌握问题的类型，了解试题题干以及各个选项所包含的信息，然后有针对性地对文章进行扫读，对有关信息进行快速定位，再将相关信息进行整合、甄别、分析、对比，有根有据地排除干扰项，选出正确答案。  
考向四 判断推理题  
这种试题常以(1)the passage is intended to...(2) the author suggests that...(3) the story implies that…(4) which point of view may the author agree to?(5) from the passage we can conclude that...(6) the purpose of the passage is to...为设问方式。这种题型的答案在原文中不是直接就能找到的，它要求考生进行合理的推断。如因果关系，文中的某些用词、语气也往往具有隐含意义，考生要将这种含义读出来。说明文常出现图示判断题，这种试题可以事物之间正确的依赖关系为命题点，要求考生判断其正确的流程顺序相互关系等。考生一定要认真阅读原文，并对照原文介绍的情况，弄清图示的差异，根据题干需要最终做出正确判断。如：动物介绍性说明文常出现动物能力判断题，考查考生对特定动物所具有能力的判断。解题时考生应认真阅读原文对动物形态活动能力的判断，了解动物的生存环境和是否会使用工具，是否善于爬行、飞翔和游泳等。     观点态度题也是判断推理题考查的内容之一。说明文的对象为客观事实,但设题以议论的表达方式抒发对该说明对象的想法。如对某种新发明的赞赏,或对某个事物的批判。这类题目常见的题干表达方式有what was the author’s attitude towards ...? 等。

高考阅读理解中，说明文为主要体裁之一。高考阅读理解题的设问主要围绕以下四方面：细节事实题、主旨大意题、推理判断题、猜测词义题。其中，说明文主要以细节事实、主旨大意和猜测词义三方面问题为主。
一、词义猜测类题型
阅读理解题中常要求学生猜测某些单词或短语的意思。历年英语高考题中均有此类题目，有的文章尽管没有专门设题，但由于文章中常常出现生词，因此，词义的猜测还是贯穿在文章的阅读理解之中。解这类题目一般是通过上下文去理解或根据构词法去猜测。判断一个单词的意思不但离不开句子，而且还需要把句子放在上下文中，根据上下文提供的线索加以猜测。运用构词法,语境等推测关键词义，可以根据以下几种方法猜测：
（一）内在逻辑关系
根据内在逻辑关系推测词义是指运用语言知识分析和判断相关信息之间存在的逻辑关系，然后根据逻辑关系推断生词词义。
1.通过同义词和反义词的关系猜词
通过同义词猜词，一是要看由and或or连接的同义词词组，如happy and gay，即使我们不认识gay这个词，也可以知道它是愉快的意思.这是高三册第八单元阅读第五段的句子：
The word ＂secure＂ in paragraph 5 line is closest in meaning to_________.
A. freefromanxiety B. anxious C. nervous D. happy
根据上下文和同义词，可以选出答案A。
二是看在进一步解释的过程中使用的同义词，如Man has known something about the planets Venus，Mars，and Jupiter with the help of spaceships. 此句中的Venus（金星）,Mars（火星）,Jupiter（木星）均为生词，但只要知道planets就可猜出这几个词都属于＂行星＂这一义域.通过反义词猜词，一是看表转折关系的连词或副词，如but，while，however等；二是看与not搭配的或表示否定意义的词语，如：He is so homely，not at all as handsome as his brother.根据not at all...handsome我们不难推测出homely的意思，即不英俊,不漂亮的意思。
2.根据因果关系猜测词义
通过因果关系猜词，首先是找出生词与上下文之间的逻辑关系，然后才能猜词。有时文章借助关联词（如because，as，since，for，so，thus，as a result，of course，therefore等等）表示前因后果。例如：
You shouldn’t have blamed him for that，for it wasn’t his fault.通过for引出的句子所表示的原因（那不是他的错），可猜出blame的词义是＂责备＂。
3.通过定义或释义关系来推测词义
例如：But sometimes，no rain falls for a long，long time. Then there is a dry period，or drought.
从drought所在句子的上文我们得知很久不下雨，于是便有一段干旱的时期，即drought，由此可见drought意思为＂久旱＂，＂旱灾＂。而a dry period和drought是同义语。这种同义或释义关系常由is，or，that is，in other words，be called或破折号等来表示。
4.通过句法功能来推测词义
例如：Bananas，oranges，pineapples，coconuts and some other kind of fruit grow in warm areas.假如pineapples和coconuts是生词，我们可以从这两个词在句中所处的位置来判断它们大致的意思。从句中不难看出pineapples，coconuts和bananas，oranges是同类关系，同属fruit类，因此它们是两样水果，准确地说，是菠萝和椰子。
5.通过描述猜词
描述即作者为帮助读者更感性地了解某人或某物而对该人或该物作出的外在相貌或内在特征的描写。例如The penguin is a kind of sea bird living in the South Pole. It is fat and walks in a funny way. Although it cannot fly，it can swim in the icy water to catch the fish.从例句的描述中可以得知penguin是一种生活在南极的鸟类.后面更详尽地描述了该鸟类的生活习性。
（二）外部相关因素
外部相关因素是指篇章（句子或段落）以外的其他知识，有时仅靠分析篇章内在逻辑关系无法猜出词义。这时，就需要运用生活经验和普通常识确定词义。例如：The snakes lithered through the grass.根据有关蛇的生活习性的知识，我们可以推断出slither词义为＂爬行＂。
（三）构词法
在阅读文章时，我们总会遇上一些新词汇，有时很难根据上下文来推断其词意，而它们对文章的理解又有着举足轻重的作用，此时，如掌握了一些常用的词根,前缀,后缀,合成等构词法知识，这些问题便不难解决了。
1.根据前缀猜测词义
例如：He fell into a ditch and lay there，semi-conscious，for a few minutes.根据词根conscious（清醒的，有意识的），结合前缀semi（半，部分的，不完全的），我们便可猜出semiconscious词义＂半清醒的，半昏迷的。＂I’m illiterate about such things.词根lit-erate意为＂有文化修养的，通晓的＂，前缀il表示否定，因此illiterate指＂一窍不通，不知道的＂。
2.根据后缀猜测词义
例如：Insecticide is applied where it is needed.后缀cide表示＂杀者，杀灭剂＂，结合大家熟悉的词根insect（昆虫），不难猜出insecticide意为＂杀虫剂＂。Then the vapor may change into droplets.后缀let表示＂小的＂，词根drop指＂滴，滴状物＂。将两个意思结合起来，便可推断出droplet词义＂小滴，微滴＂。
3.根据复合词的各部分猜测词义
例如：Growing economic problems were high-lighted by a slowdown in oil output. Hightlight或许是一个生词，但是分析该词结构后，就能推测出其含义。它是由high（高的，强的）和light（光线）两部分组成，合在一起便是＂以强光照射，使突出＂的意思。Bullfight is very popular in Spain. Bull（公牛）和fight（打，搏斗）结合在一起，指一种在西班牙颇为流行的体育运动—斗牛。
二、主旨大意类题型
主旨大意类题型主要测试学生对文章全面理解和概括的能力，提问的内容可能是全文的大意，也可能是某段的段落大意，一般不易在文中直接找到答案。怎样把握主旨大意题呢？通常有以下几种方法：
（一）阅读文章的标题或副标题
文章的标题是一篇文章的题眼，通过阅读标题或副标题可以迅速把握文章的主旨大意。
（二）寻找文章的主题句
分析篇章结构，找出文章主题。在许多情况下，尤其在阅读说明文和议论文时，根据其篇章特点我们可以通过仔细阅读短文的第一句或第二句,即文章的主题句来归纳出文章的主题.若短文由若干段组成，除仔细阅读第一段的首句外，还须仔细阅读每一段的第一句，即段落中心.通常文章的中心思想包含在文章的首句，有时也在文章的末句，其他句子都是用来说明和阐述主题句。因此，在确定文章的中心思想时，要求学生重视阅读文章的首句和末句。但也有一些文章，中心思想常常贯穿在全文中，因此要求学生综观全文，对段落的内容要融会贯通，对文章透彻理解后归纳总结。主题句的特点是：1.相对于其他句子，它表达的意思比较概括；2.主题句一般结构简单；3.段落中其他句子必定是用来解释,支撑或发展主题句所表达的思想的。
总之，为提高阅读理解能力，在阅读时应抓中心思想,作者意图及关键词语，运用联想、比较、归纳、推测等方法，得出最佳结论，选择最佳答案，不能主观臆测，把自己的观点强加进去，与文章的观点混为一谈。经过长时间有计划,有目的的系统训练，使学生加快阅读速度，提高阅读的正确性，使两者有机地统一起来，以提高学生阅读英语和运用英语进行交际的能力，为继续学习和运用英语切实打好基础.阅读是一种综合性很强的语言实际活动。我们只有进行大量的课内外阅读，掌握一定的阅读技巧，正确运用阅读方法，才能有效地提高阅读理解能力。

题组一（2019年高考真题）
Passage1(2019·全国新课标卷I，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？all 1o soisgitieoco oll.
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.
Passage2(2019·全国新课标卷I，D)
During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.
Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.
Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those least liked in elementary school, are “most likely to engage(从事)in dangerous and risky behavior.”
In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys(调查研究). “We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us."
Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date-sharing, kindness, openness — carry over to later years and make you better able to relate and connect with others.
In analyzing his and other research，Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. "Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage, ” he said.
32. What sort of girl was the author in her early years of elementary school?
A. Unkind. B. Lonely. C. Generous. D. Cool.
33. What is the second paragraph mainly about？
A. The classification of the popular.
B. The characteristics of adolescents.
C. The importance of interpersonal skills.
D. The causes of dishonorable behavior
34. What did Dr. Prinstein’s study find about the most liked kids?
A. They appeared to be aggressive.
B. They tended to be more adaptable.
C. They enjoyed the highest status.
D. They performed well academically.
35. What is the best title for the text?
A. Be Nice-You Won’t Finish Last
B. The Higher the Status, the Beer
C. Be the Best-You Can Make It
D. More Self-Control, Less Aggressiveness
Passage3(2019·全国新课标卷II，D)
Bacteria are an annoying problem for astronauts. The microorganisms(微生物) from our bodies grow uncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA overcoming this very tiny big problem? It’s turning to a bunch of high school kids. But not just any kids. It depending on NASA HUNCH high school class, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.
HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon’s students have been studying ways to kill bacteria in zero gravity, and they think they’re close to a solution(解决方案). “We don’t give the students any breaks. They have to do it just like NASA engineers,” says Florence Gold, a project manager.
“There are no tests,” Gordon says. “There is no graded homework. There almost are no grades, other than‘Are you working towards your goal?’ Basically, it’s ‘I’ve got to produce this product and then, at the end of year, present it to NASA.’ Engineers come and really do an in-person review, and…it’s not a very nice thing at time. It’s a hard business review of your product.”
Gordon says the HUNCH program has an impact(影响) on college admissions and practical life skills. “These kids are so absorbed in their studies that I just sit back. I don’t teach.” And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.
32. What do we know about the bacteria in the International Space Station?
A. They are hard to get rid of. B. They lead to air pollution.
C. They appear different forms. D. They damage the instruments.
33. What is the purpose of the HUNCH program?
A. To strengthen teacher-student relationships. B. To sharpen students’ communication skills.
C. To allow students to experience zero gravity. D. To link space technology with school education
34. What do the NASA engineers do for the students in the program?
A. Check their product. B. Guide project designs
C. Adjust work schedules. D. Grade their homework.
35. What is the best title for the text?
A. NASA: The Home of Astronauts.
B. Space: The Final Homework Frontier.
C. Nature: An Outdoor Classroom.
D. HUNCH:A College Admission Reform.
Passage4(2019·全国新课标卷I，D)
Before the 1830smost newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.
The trend, then, was toward the "penny paper"-a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.
This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830,but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny-usually two or three cents was charged-and some of the older well-known papers charged five or six cents. But the phrase "penny paper " caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.
This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.
28. Which of the following best describes newspapers in America before the 1830s?
A. Academic. B. Unattractive. C. Inexpensive. D. Confidential.
29. What did street sales mean to newspapers?
A. They would be priced higher. B. They would disappear from cities.
C. They could have more readers. D. They could regain public trust.
30. Who were the newspapers of the new trend targeted at?
A. Local politicians. B. Common people.
C. Young publishers. D. Rich businessmen.
31. What can we say about the birth of the penny paper?
A. It was a difficult process. B. It was a temporary success.
C. It was a robbery of the poor. D. It was a disaster for printers.
题组二（2018年高考真题）
Passage1(2018·全国新课标卷I，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.
Passage2(2018·全国新课标卷I，B)
Good Morning Britain’s Susanna Reid is used to grilling guests on the sofa every morning, but she is cooking up a storm in her latest role — showing families how to prepare delicious and nutritious meals on a tight budget.
In Save Money: Good Food, she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste, while preparing recipes for under £5 per family a day.

Passage3(2018·全国新课标卷II，B)
Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.
Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.
When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.
If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
24. What does the author seem to like about cherries?
A. They contain protein. B. They are high in vitamin A.
C. They have a pleasant taste. D. They are rich in antioxidants.
25. Why is fresh lemon juice used in freezing bananas?
A. To make them smell better. B. To keep their colour.
C. To speed up their ripening. D. To improve their nutrition.
26. What is “a juicer” in the last paragraph?
A. A dessert. B. A drink.
C. A container. D. A machine.
27. From which is the text probably taken?
A. A biology textbook. B. A health magazine.
C. A research paper. D. A travel brochure.
Passage4(2018·北京卷，B)
Find Your Adventure at the Space and Aviation(航空) Center
If you’re looking for a unique adventure, the Space and Aviation Center (SAC) is the place to be. The Center offers programs designed to challenge and inspire with hands-on tasks and lots of fun.
More than 750,000 have graduated from SAC, with many seeking employment in engineering, aviation, education, medicine and a wide variety of other professions. They come to camp, wanting to know what it is like to be an astronaut or a pilot, and they leave with real-world applications for what they’re studying in the classroom.
For the trainees, the programs also offer a great way to earn merit badges(荣誉徽章). At Space Camp, trainees can earn their Space Exploration badge as they build and fire model rockets, learn about space tasks and try simulated(模拟) flying to space with the crew from all over the world. The Aviation Challenge program gives trainees the chance to earn their Aviation badge.

题组三（2017年高考真题）
Passage1(2017·全国新课标卷I，D)
A build-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 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 from .
A. the plastic tube B. outside the hole
C. the open air D. beneath the sheet
Passage2(2017·全国新课标卷II，B)
Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle —named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.
Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t help if you’re stuck in traffic. The car needs a runway.
Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.
Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia
says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.
28. What is the first paragraph mainly about?
A. The basic data of the Transition.
B. The advantages of flying cars.
C. The potential market for flying cars.
C. The designers of the Transition.
29. Why is the Transition unlikely to show up in too many driveways?
A. It causers traffic jams.
B. It is difficult to operate.
C. It is very expensive.
D. It burns too much fuel.
30. What is the government’s attitude to the development of the flying car?
A. Cautious B. Favorable.
C. Ambiguous. D. Disapproving.
31. What is the best title for the text?
A. Flying Car at Auto Show
B. The Transition’s First Flight
C. Pilots’ Dream Coming True
D. Flying Car Closer to Reality
Passage3(2017·全国新课标卷II，D)
When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked .It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.
In study after study, it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to ＂overhear＂ the cry. So information was exchanged, but it wasn’t a true, intentional back and forth.
Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的)
 than the world we can see and hear. Our senses are weak. There’s a whole lot going on.
32. What does a plant do when it is under attack?
A. It makes noises.      B. It gets help from other plants.
C. It stands quietly     D. It sends out certain chemicals.
33. What does the author mean by ＂the tables are turned＂ in paragraph 3?
A. The attackers get attacked.
B. The insects gather under the table.
C. The plants get ready to fight back.
D. The perfumes attract natural enemies.
34.Scientists find from their studies that plants can .
A. predict natural disasters
B. protect themselves against insects
C. talk to one another intentionally
D. help their neighbors when necessary
35.what can we infer from the last paragraph?
A. The world is changing faster than ever.
B. People have stronger senses than before
C. The world is more complex than it seems
D. People in Darwin’s time were imaginative.
Passage4(2017·全国新课标卷III，C)
After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
28. What is the text mainly about?
A. Wildlife research in the United States.
B. Plant diversity in the Yellowstone area.
C. The conflict between farmers and gray wolves.
D. The reintroduction of wolves to Yellowstone Park.
29. What does the underlined word ＂displaced＂ in paragraph 2 mean?
A. Tested. B. Separated.
C. Forced out. D. Tracked down.
30. What did the disappearance of gray wolves bring about?
A. Damage to local ecology.
B. A decline in the park’s income.
C. Preservation of vegetation.
D. An increase in the variety of animals.
31. What is the author’s attitude towards the Yellowstone wolf project?
A. Doubtful. B. Positive.
C. Disapproving. D. Uncaring.

题组四（名校模拟题）
Passage 1(河南省实验中学2019届高考全真模拟)
Solar energy systems & power plants do not produce air pollution, water pollution, or greenhouse gases. Using solar energy can have a positive, indirect effect on the environment, when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment.
However, some poisonous materials and chemicals are used to make the photovoltaic ( 光电池的) cells that convert sunlight into electricity. Some solar thermal (保热的) systems use potentially hazardous liquids to transfer heat. Leaks of these materials could be harmful to the environment. U. S. environmental laws regulate the use and settlement of these types of materials.
As with any type of power plant, large solar power plants can affect the environment near their locations. The placement of the power plant may have long-term effects on the habitats of native plants and animals. Some solar power plants may require water for cleaning solar collectors and concentrators or for cooling turbine generators. Using large volumes of ground water or surface water in some dry locations may affect the ecosystems that depend on these water resources. In addition, the beam of concentrated sunlight a solar power tower creates can kill birds and insects that fly into the beam.
The amount of solar energy that the earth receives each day is many times greater than the total amount of all energy that people consume each day. However, on the surface of the earth, solar energy is a variable and irregular energy source. The amount of sunlight and the intensity of sunlight varies by time of day and location. Weather and climate conditions affect the availability of sunlight daily and on a seasonal basis. The type and size of a solar energy collection and conversion system determines how much of the available solar energy we can convert into useful energy.
1. Which of the following best explains "hazardous" underlined in paragraph 2?
A. inexpensive B. dangerous
C. ineffective D. abnormal
2. What influence can large solar power plants have on the locations?
A. Polluting the ground water.
B. Protecting the habitats of plants and animals.
C. Damaging the local natural balance.
D. Attracting birds and insects to the area.
3. What does the last paragraph mainly tell us?
A. Different areas receive different amount of solar energy.
B. How to convert solar energy into useful energy.
C. The relationship between solar energy collection and the sunlight.
D. Some factors that influence the amount of solar energy collection.
Passage 2(山东省潍坊市2019届高三上学期期中考试)
Digital grounding is when parents or caregivers limit or completely take away access to technology from children. According to a study conducted by Pew Research，65％of parents have digitally grounded their teen by taking away their teen’s cellphone or internet access as punishment.
Because children are so connected with their technologies, digital grounding may seem like a logical step for parents. Take away a child’s most cherished item and they will quickly learn from their behavior. But the idea of digital grounding isn’t as clear—cut as that. Instead, it may be a lose-lose situation for parents and kids, alike.
For most parents, the goal of grounding isn’t to make their children unhappy or sad. It is to teach a lesson in the hope that they won’t engage in whatever behavior got them in trouble in the first place. Unfortunately, though, digital grounding is often just punishment, not discipline. If a child stays out past curfew(约定的最晚回家时间), a punishment would be hitting or yelling at them. Discipline would be not letting them go out the next weekend because they failed to follow rules.
We’ve all been there—we’ve caught our child doing something wrong and in the heat of the moment laid out a strict punishment. We may have been feeling hot—headed, embarrassed, or upset. Often, though, these punishments don’t align with the bad behavior.
While digital grounding may solve the problem temporarily, it won’t provide children with the guidance they need to act appropriately in the future. Instead of grounding, show your child what they did wrong and give them the chance to act differently. This way, they will learn from their mistakes in a practical manner and figure out ways to be safe and smart with technology.
There’s no denying it：technology is here for the long-haul. This is why some parenting experts don’t recommend digitally grounding your children. It doesn’t focus on the end goal of safe behavior. They recommend teaching them good habits as soon as possible, rather than taking away their technology. By digitally grounding them, you are putting a bandage over the wound, rather than treating it.
Now, when we say that digital grounding is a lose-lose situation, we’re not saying that disciplining your children in general is a lose—lose situation. Discipline is a great way to teach children lessons, when used appropriately.
1. Which of the following is a form of discipline?
A. Hitting or yelling at children.
B. Laying out a strict punishment in the heat of the moment.
C. Taking away access to cellphones from children completely.
D. Forbidding kids to go out the next weekend if they stay out past curfew.
2. What does the author think of digital grounding?
A. It benefits children greatly.
B. It is no better than disciplining.
C. Parents can use it to correct kids’behavior.
D. Neither parents nor children gain benefits from it.
3. What does the author suggest parents do instead of grounding?
A. Give kids more free time. B. Act appropriately in public.
C. Help kids form good habits. D. Put a bandage over the wound.
4. What’s the purpose of the text?
A. To inform us of ways of punishing kids.
B. To explain what digital grounding means.
C. To show how to parent children in digital times.
D. To prove digital grounding is not a good parenting way.
Passage 3(湖南省三湘名校教育联盟2019届高三大联考)
Not only does the use of plastic water bottles hurt your wallet, it also increases pollution and wastes energy and water. Only 23 % of all plastic in America ends up in a recycling bin， meaning over $ 1 billion worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho.
It is a convenient, clear water bottle that can either be drunken or eaten. To drink it, you can either peel off the membrane(薄膜）or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it，you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡）without arriving with a very wet truck. However，they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events» such as marathons» music festivals，and sporting events， where tons of plastic bottles are used，and frequently left behind as litter. And too much plastic is sure to do harm to the environment，which could account for their purpose of such a new invention.
The team has been working for the past two years to develop the technology and materials needed to produce Ooho； they have recently applied a patent for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles* It has appeared at events in London, San Francisco , Boston, at conferences, festivals，and so on.
Ooho is catching many people’s attention and has raised over $ 1 million and gained 1，000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer’s interest while the production machine is getting up and running. It is quickly making a rise, so keep an eye out this year for these bottles of the future.
1.How is most plastic dealt with in America?
A. It’s sold. B. It’s recycled.
C. It’s buried. D. It’s wasted.
2.Why did the team invent Ooho?
A. To make a profit for a company. B. To protect the environment.
C. To make people eat as they drink. D. To reduce the cost of plastic bottle.
3.What can we infer about Ooho from the text?
A. It is easy and safe to ship it in large amounts.
B. It has become popular since it began to be sold.
C. It might be sold at a lower price than plastic bottles.
D. It cost the team a lot of money to develop the technology.
4.What does the author really want to say in the last paragraph?
A. Ooho is to be a success in the future.
B. Ooho is being supported by smart people.
C. Ooho is taking the place of plastic bottles now.
D. Ooho is being produced to attract more investors,
Passage 4（滨州市2018届高三5月第二次模拟 ）
Educators across the US are calling for major changes to the admissions process in higher education. The Harvard school of Greduate Education, along with 80 other schools and organizations, released a report called "Turning the Tide Making Caring Common” in January, 2016. The report argues that the process schools use to choose students causes major problems.
David Hawkins is the Executive Director for Educational Content and Policy at the National Association for College Admissions Counseling. Hawkins told Voice of America that most colleges and universities require many things from students when they apply. Schools usually ask for an essay describing a student's interests or why they want to study at that school. The schools also ask for letters from teachers or other responsible adults describing why a student is a good candidate. But, Hawkins says, the area that schools are most concerned about is a student's high school grades and standardized test results.
The report suggests that paying attention to academic success over other qualities works well for some students but hurts others. In addition, academic success is not the most important quality a student should have. More attention should be paid to showing whether or not a student wants to do well in the world, according to the report.
The report goes on to state that the best way to change the admissions process is by changing college applications. It suggests that schools should ask for evidence that students care about other people. But the report does have its critics. Bob Schaeffer, Public Education Director for the National Center for Fair and Open Testing, said that every few years, someone makes the same argument for changes, but no real change has happed yet. Even many of the schools that agree with the report still make no changes.
Lloyd Thacker, Executive Director of the Education Conservancy, said that until a majority of schools agree to make the changes, there will still be problems. However, he said, the admissions process was better in the past. If bad changes can affect the process, so can good ones.
1.What is the problems of the admissions process according to the report?
A. The schools ask too many things from the applying students.
B. The schools attach too much importance to students’ academic records
C. The number of students getting admitted is too small
D. Admissions officers consider too many unimportant factors
2.What is usually missing in an essay?
A. The reasons to attend the school
B.A description of interests
C. Recommendation letters from adults
D. Evidence that students care about others
3.Bob Schaeffer argues that _________.
A. not all changes are good
B. the largest schools are expected to make changes first
C.no schools currently agree with the report
D. some schools don’t make changes even if they agree
4.What’s Lloyd Thacker’s attitude toward the possible change in the admissions process?
A. Confident B. Negative
C. Doubtful D. Unclear
