句子结构较复杂，语法分析较困难。为了描述一个客观事物，严密地表达自己的思想，作者经常会使用集多种语法现象于一体的长句。3. 常使用被动语态，尤其是一些惯用被动句式。命题形式：命题特点科普类阅读的主要命题形式有事实细节题、词义猜测题、推理判断题以及主旨概括题等，其中推理判断题居多。方法概述高考对说明文的考查多为科普说明文，它是阅读理解重要内容，也是高考考查难点。科普类“阅读理解”题愈来愈受到的青睐而科普类文章往往具有跨学科行文逻辑性强等特点,要求考生能从文章的整体逻辑以及重要细节上全面把握【试题特点】 注重学科渗透,行文逻辑性强,内容抽象 贴近学生的学习生活实际,有利于激发学生的思维,对选拔优秀考生有一定的作用 能全面地考查学生的综合阅读能力和运用所学知识去分析解决实际问题的能力 (4)科学方法图示判断题 科普说明文常出现科学方法图示判断题，这种试题或以生物依赖关学科网系为命题题点，要求考生判断正确的生物依赖关系；或以工艺流程为命题题点，要求考生判断正确的流程顺序，或以生产方法为命题题点，要求考生判断正确的生产方法；或以机械配制为命题题点，要求考生判断正确的机械配制。解题时一定要认真阅读分析原文对生物依赖关系、发明创造诞生过程和工艺流程过程的介绍，并且边读边画简易草图，以提高理解准确率。分析备选项时应对照原文介绍情况，找出各图不同之处，以便最终做出正确判断。命题方式考点一、细节事实理解。一篇文章必然是由许多具体的细节、具体的内容构成的，所有这些信息以某种顺序（时间、空间、情感变化等）排列起来，来进一步解释或阐释主题，体现文章的主旨大意。细节理解题目主要考查学生对文章具体事实和细节的理解能力，属于表层理解题学科网范畴，难度较小，但在整个阅读理解题中所占比例最大，细节理解题多从文章的某个具体事实或细节出发来设计题目。此类题通常根据文章具体内容来设问，也常使用下列方式来提问1.Which of the following statements is(not) true/correct?2.Which of the following is not mentioned?3.All of the following are true except.4.According to the passage,when/where/why/how/how/what/which,etc.？1.直接事实题 在解答这类问题时要求学生抓住题干文字信息，采用针对性方法进行阅读，因为这类题的答案在文章中可以直接找到。 如：A giant dam was built many years ago to control the Colorado River in the U.S.This dam was built to protect the land and houses around the river.This huge dam is in the Black Canyon.It is possible to drive a car from one side of the river to the other on a road，which is on the top of the dam.This dam is so big that there is an elevator inside.The elevator goes down forty-four stories from the road to the bottom.There is enough concrete in this dam to build a highway from New York to San Francisco.Thousands of people worked on this dam for five years.This huge dam was called Boulder Dam when it was finished in 1936.Later it was renamed Hoover Dam in honor of a president of the United States.Hoover Dam，one of the highest dams in the world，is situated between the states of Arizona and Nevada.Q：Hoover Dam lies_ .A.between Arizona and NevadaB.in the Black CanyonC.between New York and San FranciscoD.both A and B【解析】由第二段的第一句话和最后一段的最后一句话可得出正确答案是D项。2.间接事实题 解答此类题，需要结合上下文提供的语境和信息进行简单的概括和判断或者要进行简单的计算。Invited by Mr.Ye Huixian，host of the well-received TV programme“Stars Tonight”，Miss Luo Lin，Miss Asia of 1991，appeared as the guest hostess on the Shanghai TV screen last Sunday.Born in Shanghai and taken to Hongkong when she was only six years old，Luo Lin has never dreamed of being Miss Asia.Her childhood dream was to be an air hostess.Before she took part in the petition，she had been an airhostess in Cathay Airline for seven years.However， it still took her three months to learn the art of walking on the stage，dancing,singing,making-up and other proper manners，designed by the Asia TV Station.“Its really a hard job for me.I wont enter for such petition any more.Anyhow，I am quite lucky.I am also glad to have had more chance to work for the social welfare since I won the title.This time，in Shanghai，Id love to make a deep impression on my TV audience，”said Luo Lin with a sweet smile.Q：Which of the following is NOT true?A.Luo Lin is a native of Shanghai.B.Luo Lin moved to Hongkong with her parents.C.Luo Lin won the title of Miss Asia in 1991.D.Asia TV Station helped Luo Lin to bee Miss Asia.【解析】A、C和D项都可在原文找到答案，而B项原文所给的是：taken to Hongkong可判断不是moved to Hongkong with her parents，因此选B。 3、数据推算。If you register both the VIEW qualification course and the Forum at the same time,you will save_ .A.$100B.$300C.$350D.$400 这类题目要求学生就文章提供的数据，以及数据与文中其他信息的关系做简单计算和推断。在做此类题时：1.要抓住并正确理解与数据有关的信息含义。2.弄清众多信息中那些属于有用信息，那些属于干扰信息。3.不要孤立看待数字信息，而要抓住一些关键用语的意义。考点二、主题理解或写作意图推断。一、主旨阅读理解题考查的内容1.短文的标题（title,headline）；2.短文或段落的主题（subject）；3.中心思想(main idea)；4.作者的写作目的(purpose)。二、此类题的设问方式1.What would be the best title for the text?2.What does the second paragraph mainly discuss?3.What is the passage mainly about?4.The main purpose of announcing the above events is_.考点三、推理推断。推理题要求考生根据文章提供的事实和线索进行逻辑推理，推断出作者没有提到或者没有明说的事实或者可能发生的事实。这类题旨在考查学生透过词语的字面意义去理解作者的言外之意或弦外之音的能力，属于深层理解题。此类题的设问常常包括infer,imply,suggest,conclude 等词，这类题的设问方式主要有：1.We can infer from the Passage that_.2.What can be inferred from the Passage?3.Which of the following can be inferred from the Passage?4.It can be inferred from Paragraph 3 that_.5.The author suggests in this paragraph that_.6.The writer implies that_.7.It can be inferred that_.8.It can be concluded from the Passage that_.9.On the whole,we can conclude that_.10.From the text we can conclude that_.11.After reading the Passage we may conclude that_.12.What conclusion can be drawn from the Passage?13.The author is inclined to think that_.14.When the writer talks about,what he really means is that_.15.Whats the writers attitude/feeling towards.?16.In the writers opinion,.考点四、词义、句义猜测。词义猜测阅读理解题考查对文中关键词语的理解。在阅读理解题中，所考查的词或短语的意义往往不停留在字面上，要根据语境来判断。此类题的设问方式主要有1.The word “.”in Line.means/can be replaced by.2.As used in the passage,the phrase “.”suggests.3.From the passage,we can infer that the word/phrase “.” is/referred to.4.The word “.” is closest in meaning to.猜词是应用英语的重要能力，也是高考中常用的题型。它不但需要准确无误地理解上下文，而且要有较大的泛读量，掌握或认识较多的课外词汇。我们要学会“顺藤摸瓜”，通过构词、语法、定义、同位、对比、因果、常识、上下文等线索确定词义。1.定义法。如:Annealing is a way of making metal softer by heating it and then letting it cool very slowly.句子给予annealing 以明确的定义，即 “退火”。It will be very hard but also very brittlethat is,it will break easily.从后面的解释中我们可以了解到brittle 是“脆”的意思。The herdsman,who looks after sheep，earns about 650 yuan a year.定语从句中 looks after sheep 就表明了 herdsman 的词义为“牧人”。2.同位法。如:They traveled a long way and at last got to a castle,a large building in old times.同位语部分a large building in old times 给出了 castle 的确切词义，即“城堡”。We are on the night shiftfrom midnight to 8 a.m.this week.两个破折号之间的短语很清楚地表明night shift 是“夜班”的意思。3.对比法。如:She is usually prompt for all her class,but today she arrived in the middle of her first class.but一词表转折，因此but 前后的意思正相反。后半句的意思是“她今天第一节上了一半才来”，因此反向推理，可得出她平时一向“准时”的结论。4.构词法(前缀、后缀、复合、派生等)。如:Perhaps,we can see some possibilities for next fifty years.But the next hundred?possibility 是 possible 的同根名词,据此可以判断定 possibility 意思是“可能性”。5.因果法。如：The lack of movement caused the muscles to weaken.Sometimes the weakness was permanent.So the player could never play the sport again.从后面的结果“永远不能再运动”中，可以推测 permanent 的意思为“永远的，永久”。体验高考xx广东卷 DScientists today are making greater effort to study ocean currents(洋流). Most do it using satellites and other hightech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special wayby studying movements of random floating garbage. A scientist with many years experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap_meets to try and match left and right shoes to sell or wear.Ebbesmeyer found out in his researches that the shoesabout 60，000 in totalfell into the ocean in a shipping accident. He phoned the shoe pany and asked if they wanted the shoes back. As expected, the pany told him that they didnt. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.The Pacific Northwest is one of the worlds best areas for beachbing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachbers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1，600 shoes. With this data, he and a colleague were able to test and improve a puter programme designed to model ocean currents, and publish the findings of their study.As the result of his work, Ebbesmeyer has bee known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachbers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.41. The underlined phrase “swap meets” in Paragraph 1 is closest in meaning to “_”A. fitting roomsB. trading fairsC. business talksD. group meetings42. Ebbesmeyer phoned the shoe pany to find out _A. what caused the shipping accidentB. when and where the shoes went missingC. whether it was all right to use their shoesD. how much they lost in the shipping accident43. How did Ebbesmeyer prove his assumption?A. By collecting information from beachbers.B. By studying the shoes found by beachbers.C. By searching the web for ocean currents models.D. By researching ocean currents data in the library.44. Ebbesmeyer is most famous for _A. travelling widely the coastal cities of the worldB. making records for any lost objects on the seaC. running a global currents research associationD. phoning about any doubtful objects on the sea45. What is the purpose of the author in writing this passage?A. To call peoples attention to ocean pollution.B. To warn people of shipping safety in the ocean.C. To explain a unique way of studying ocean currents.D. To give tips on how to search for lost objects on the beach.【文章大意】 这是一篇说明文。文章主要介绍了海洋专家Ebbesmeyer研究洋流的一种特殊的方法。41. B词义猜测题。swap意为“交换”。由相似表达sports meet可以推出meet的含义，再从文中“There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.”可以确定答案为B。43. A细节理解题。根据第三段的“there is a group of serious beachbers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed.”可知Ebbesmeyer是从海滩搜寻者那里得到信息的。故选A。44. D细节理解题。根据最后一段的“Ebbesmeyer has bee known as the scientist to call with questions about any unusual objects found floating in the ocean.”可知答案为D。其中call对应phoning，而unusual对应doubtful。45. C写作意图题。说明文要注意主旨句在首尾段的情况，尤其要注意首尾段出现的but或者however等转折词，转折后是作者要表达的重点。根据第一段的“However, ocean expert Curtis Ebbesmeyer does it in a special wayby studying movements of random floating garbage.”可知作者的写作目的是解释研究洋流的一种特殊的方法。故选C。xx山东卷 DHow fit are your teeth? Are you lazy about brushing them? Never fear: an inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone. The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection. The toothbrush will be able to teach you to brush right (dont forget the insides of the teeth！) and make sure youre brushing long enough. “Its kind of like having a dentist actually watch your brushing on a daytoday basis，” says Thomas Serval, the French inventor. The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun，” Serval says. Serval says he was inspired by his experience as a father. He would e home from work and ask his kids if they had brushed their teeth. They said “yes”， but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed. The pany says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The US is the first target market. Serval says that one day, itll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush. 56Which is one of the features of the Kolibree toothbrush? AIt can sense how users brush their teeth.BIt can track users school performance. CIt can detect users fear of seeing a dentist.DIt can help users find their phones. 57What can we learn from Servals words in Paragraph 3? AYou will find it enjoyable to see a dentist. BYou should see your dentist on a daytoday basis. CYou can brush with the Kolibree as if guided by a dentist. DYoud like a dentist to watch you brush your teeth every day. 58Which of the following might make the Kolibree toothbrush fun? AIt can be used to update mobile phones.BIt can be used to play mobile phone games. CIt can send messages to other users.DIt can talk to its developers. 59What is Paragraph 5 mainly about? AHow Serval found out his kids lied to him. BWhy Serval thought brushing teeth was necessary. CHow Serval taught his kids to brush their teeth. DWhat inspired Serval to invent the toothbrush. 60What can we infer about Servals children? AThey were unwilling to brush their teeth. BThey often failed to clean their toothbrushes. CThey preferred to use a toothbrush with a dry head. DThey liked brushing their teeth after Serval came home. 61What can we learn about the future development of the Kolibree? AThe brush handle will be removed. BA mobile phone will be built into it. CIt will be used to fill holes in teeth. DIt will be able to check users teeth. 【文章大意】 这是一篇说明文。文章主要介绍法国发明家Thomas Serval根据自己的经历发明了一款多功能的电动牙刷。56A细节理解题。根据第一段的“An electric toothbrush senses how long and how well you brush”可知这个牙刷的功能特点。57C推理判断题。根据第三段可知，使用这款牙刷刷牙就好像牙医在指导着你刷牙。故选C。58B细节理解题。根据第四段内容可知答案为B。61D推理判断题。根据最后一段内容可知将来这款牙刷会安上摄像机以检查牙齿上的洞。 xx陕西卷 CWhy do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers conclude that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favourite TV show is over.According to Dr Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers markets where they have a choice of fresh fruits, vegetables, and eggs as well as highquality meats for each meal.After a visit to the United States, Mireille Guiliano, author of French Women Dont Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesityor extreme overweightamong adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17%and is growing.53. In what way are the French different from Americans according to Dr Joseph Mercola?A. They go shopping at supermarkets more frequently. B. They squeeze eating between the other daily activities.C. They regard eating as a key part of their life style.D. They usually eat too much canned and frozen food.54. This text is mainly the relationship between _A. Americans and the French B. life style and obesityC. children and adults D. fast food and overweight55. The text is mainly developed _A. by contrast B. by space C. by process D. by classification56. Where does this text probably e from?A. A TV interview. B. A food advertisement. C. A health report. D. A book review.【文章大意】 本文是一篇科普说明文，大意是说美国康奈尔大学的专家的一项研究：美国人和法国人的饮食习惯对各自的体重的影响。53.

Although known as the love hormone, it affects the sexes differently.“Women tend to be social in their behaviour. They often share with others. But men lend to be petitive. They are trying to improve their social status，” said Professor Ryan.Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.Further researches showed that in men the hormone oxytocin improves the ability to recognize petitive relationships, but in women it raises the ability to recognize friendship. Professor Ryans recent experiment used 62 men and women aged 20 to 37. Half of the participants(参与者) received oxytocin. The other half received placebo(安慰剂)After a week, the two groups switched with participants. They went through the same procedure with the other material.Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from petition. And their answers should be based on gestures, body language and facial expressions.The results indicated that, after treatment with oxytocin, mens ability to correctly recognize petitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.Professor Ryan thus concluded, “Our experiment proves that the hormone oxytocin can raise peoples abilities to better distinguish different social interactions. And the behaviour differences between men and women are caused by biological factors(因素) that are mainly hormonal.”47. What causes men and women to behave differently according to the text? A. Placebo. B. Oxytocin.C. The gesture. D. The social status.48. What can we learn from Professor Ryans previous experiment?A. Oxytocin affects our behaviour in a different way.B. Our body lets out oxytocin when we are deep in love.C. Our body produces oxytocin when we feel unhappy about others success.D. Oxytocin improves our abilities to understand peoples behaviour differences.49. Why did Professor Ryan conduct the recent experiment?A. To test the effect of oxytocin on the ability to recognize social interactions.B. To know the differences between friendship and petition.C. To know peoples different abilities to answer questions.D. To test peoples understanding of body language.50. The author develops the text by _A. explaining peoples behavioursB. describing his own experiencesC. distinguishing sexual differencesD. discussing research experiments48.
