    15．How did the sea horse get its name？It's not hard to guess．The top half of this fish looks like a small horse．But looking at the sea horse's tail，you might think"sea monkey"is a better name．Then there's the sea horse's pouch （育儿袋）．"Sea kangaroo"might also be a good name for this fish．
        Sea horses live in warm ocean waters all over the world．They keep safe from other fish by hiding in plants and grasses that grow under the sea．They can also change colors to match their surroundings．A sea horse remains in one place for hours at a time by winding its tail around a plant．It feeds on live food，such as small shrimp．For a fish that doesn't move around much，the sea horse eats a lot-in just one day，a sea horse can eat 3，000 shrimp!
    A sea horse keeps the same mate for its whole life，and it's the male sea horse that gives birth to baby sea horses．How does this happen？Baby sea horses start out as eggs，which come from the female's body．The male carries the eggs in its pouch for about three weeks until they hatch．Soon after the babies are born，the female gives her mate a new set of eggs．
        Sadly，the number of sea horses is becoming smaller．Why is this happening？Some places where sea horses once lived have been filled in to make new land．Also，many sea horses are caught and sold as aquarium fish．This really is not a good idea because most sea horses don't live long in aquariums．The best place for a sea horse is the ocean．
    60．The sea horse got its name because of itsB
    A．skin          B．head         C．pouch            D．tail
    61．We can learn from the text that sea horsesC
    A．like to move around               B．live in cold ocean waters
    C．feed on small live shrimp         D．change colors with the temperature
    62．What does a female sea horse do with her eggs？D
    A．She hatches them．
    B．She hides them in sea grasses．
    C．She carries them around．
    D．She puts them in the male's pouch．
    63．Why is the number of sea horses becoming smaller？B
    A．Because they grow at a very low speed．
    B．Because their homes are being destroyed．
    C．Because they are killed by people for food．
    D．Because their food is becoming less and less．

    分析 本文主要讲解了有关海马的知识，讲到了海马名字的来历，生活习性，如何繁殖及数量越来越少的原因．

    解答 60．B 细节题，根据第一段It's not hard to guess．The top half of this fish looks like a small horse．可知，是因为海马的头部像马而得名，故选B．
    61．C 细节题，根据第二段It feeds on live food，such as small shrimps．可知它们以小虾为食，故选C．
    62．D 细节理解题．文章第三段介绍了海马的繁殖过程．根据"Baby sea horses start out as eggs…the female gives her mate a new set of eggs．"可知答案为D．
    63．B　细节理解题．最后一段提到海马数量减少的两个原因：一是人们填海造田，破坏了它们的生存环境；一是人们捕捉海马来卖，故答案为B

    点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
    2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
    3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．

    12．As more and more people speak the global languages of English，Chinese，Spanish，and Arabic，other languages are rapidly disappearing．In fact，half of the 6，000～7，000languages spoken around the world today will likely die out by the next century，according to the United Nations Educational，Scientific，and Cultural Organization （UNESCO）．
    In an effort to prevent language loss，scholars from a number of organizations-UNESCO and National Geographic among them-have for many years been documenting dying languages and the cultures they reflect．
    Mark Turin，a scientist at the Macmillan Centre，Yale University，who specializes in the languages and  oral traditions of the Himalayas，is following in that_tradition．His recently published book，A Grammar of Thangmi with an Ethnolinguistic Introduction to the Speakers and Their Culture，grows out of his experience living，working，and raising a family in a village in Nepal．
    Documenting the Thangmi language and culture is just a starting point for Turin，who seeks to include other languages and oral traditions across the Himalayan reaches of India，Nepal，Bhutan，and China．But he is not content to simply record these voices before they disappear without record．
    At the University of Cambridge Turin discovered a wealth of important materials-including photographs，films，tape recordings，and field notes-which had remained unstudied and were badly in need of care and protection．
    Now，through the two organizations that he has founded-the Digital Himalaya Project and the World Oral Literature Project-Turin has started a campaign to make such documents，found in libraries and stores around the world，available not just to scholars but to the younger generations of communities from whom the materials were originally collected．Thanks to digital technology and the widely available Internet，Turin notes，the endangered languages can be saved and reconnected with speech communities．
    64．What does"that tradition"in Paragraph 3refer to？A
    A．Having full records of the languages．
    B．Writing books on language teaching．
    C．Telling stories about language users．
     D．Living with the native speakers．
    65．What is Turin's book based on？D
    A．The cultural studies in India．
    B．The documents available at Yale．
    C．His language research in Bhutan．
    D．His personal experience in Nepal．
    66．Which of the following best describes Turin's work？C
    A．Write，sell and donate．
    B．Record，repair and reward．
    C．Collect，protect and reconnect．
    D．Design，experiment and report．

    3．Many of us mistakenly believe that it's wrong to think we have any good qualities．We may spend a lot of time blaming ourselves for our negative qualities，thinking that self criticism is the key to improving our performance．However，a constant focus on our supposed shortcomings can stop our efforts to make friends with other people．How can we believe that others could like us if we believe our inner being is flawed（有缺陷）？
    If someone seems to dislike you，the reason for that dislike might have little or nothing to do with you．The person who doesn't like you might be fearful，or shallow，or busy or shy．Perhaps you and that person are simply a mismatch for each other at this particular time．
    Don't take yourself out of the game by deciding that your flaws are bigger than your good qualities．In fact，some of the very qualities you consider to be flaws may be irresistible to someone else．For all the factors that might cause one person to reject you，there are at least as many factors that will work in your favor with someone else．
    You might be thirty pounds over your ideal weight，but you may have a wonderful laugh and a real enthusiasm for life．There are many people who don't mind your extra pounds．You may drive a shabby car，but you might be a great dancer and a loyal friend．There are people out there looking for loyalty，or fun，or sweetness，or wisdom，and the package it comes in is not important．If you are worried that you are not beautiful enough to attract friends，keep in mind that not everyone is looking for physical beauty in their friends．You can decide to feel inferior（自卑） because you don't have much money and you don't drive a nice car．You can believe that this is the reason that you don't have many friends in your life．On the other hand，if you are very wealthy you may be suspicious that everyone is after your money and that nobody really likes you as a person．
    The point is that you can focus on just about anything and believe it's the reason you do not have friends and cannot make any．

    36．According to the authorD plays an important role in making friends．
    A．admitting your shortcomings  B．self criticism  C．modesty  D．confidence
    37．If you are not liked by a person，C．
    A．you should find the reason in yourself
    B．you'd better talk with the person face to face
    C．you may not be the one to be blamed
    D．you and that person misunderstand each other
    38．We can learn from the third paragraph thatB．
    A．your good qualities may turn out to be your flaws
    B．your weakness may also be your strengths in some way
    C．your negative qualities cause a person to reject you
    D．you'll have few friends if your flaws are bigger than your good qualities
    39．Which of the following is true according to the author？C
    A．It is important to lose weight．
    B．It is easier for a wealthy person to make friends．
    C．Inner qualities are more important than physical appearance．
    D．If you are not beautiful enough，try to improve your physical beauty．
    40．What do you think the author is most likely to suggest if he continues to write？A
    A．How to find your good qualities．
    B．How to make friends．

    10．A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it．Some children reach eagerly for the treat they see．Some last a few minutes before they give in．But others are determined to wait until the last moment．
    By the time the children reach high school，something remarkable has happened．A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular，adventurous，confident and dependable．The children who gave in to temptation（诱惑） early were more likely to be lonely，easily frustrated and inflexible（顽固的）．
    Actually，the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ test．
    The hardware of the brain and the software of the mind have long been scientists'concerns．But brain theory can't explain what we wonder about most，like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul．
    Here comes the theory of Daniel Goleman，writer of Emotional Intelligence：when it comes to predicting people's success，brain ability measured by IQ may actually matter less than the qualities of mind once thought of as"character"．
    EQ is not the opposite of IQ．What researchers have been trying to understand is how they work together； how one's ability to handle stress，for instance，affects the ability to concentrate and put intelligence to use．Among the ingredients （要素） for success，researchers now generally agree that IQ counts for about 20%； the rest depends on everything from social class to luck．
    While many researchers in this relatively new field are glad to see emotional issues finally taken seriously，some few fear EQ causes misuse．

    66．The experiment with the four-year-olds makes it clear thatC．
    A．the age of 4 is a proper time for scientific experiment
    B．emotional intelligence won't show up until adolescence
    C．the ability of self-control plays a role in personal success
    D．candy can be used to measure a person's emotional intelligence
    67．Which of the following is TRUE of EQ and IQ according to the text？D
    A．There is no link between EQ and IQ．
    B．The higher a person's IQ is，the higher his or her EQ is．
    C．Some people can be blessed with lots of both，but some with little of either．
    D．Scientists are trying to discover the way in which EQ and IQ work together．
    68．The underlined word"upbeat"in Paragraph 4 probably means"D"．
    A．kind        
    B．floating        
    C．excited         
    D．optimistic
    69．Why does the author mention the experiment at the beginning of the text？C
    A．To amuse both the children and readers．
    B．To prove the scientist's wisdom．
    C．To introduce the topic of the text．
    D．To show us how to do an IQ test．
    70．What is most likely to be written in the paragraph that follows？B
    A．Information about famous people with high EQ．
    B．Examples showing the opposite voice about EQ．
    C．Some reasons why EQ is relatively new field．
    D．Strong demands for basic emotional education．

    20．Seeing in Stereo
    Have you wondered why you have two eyes and why they are set close together on the front of your face？The reasons are simple and important to the way you see the rest of your world．
    Your eyes are like two small cameras．A camera catches an image（影像）of an object and records it on film．Similarly，when you look at something，each eye takes in what it sees and sends this image to the back of the eyeball．Because your eyes are set close together，they view the world from about the same height but from slightly different angles．Working as a team，the eyes send the images to your brain，which puts them together into a single，centered image．
    Seeing in stereo means seeing with two eyes working together，which is called stereoscopic sight．This allows you to view the world in three dimensions，or 3-D．Seeing depth helps you to judge the distance between you and the objeets you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it．If images are coming from only one eye，however，only two of these dimensions-height and width-can be perceived．A world seen with one eye is thus two-dimensional，as in a photograph．
    Now consider why your two eyes are on the front of your face．Think of other animals with this same arrangement．They are all animals that hunt，like lions and wolves．Their eyes face directly in front of them．This provides a field of sight about 180degrees wide，which is called binocular sight．On the other hand，animals that are hunted have eyes on the sides of the head，which  Drovides nearly 360-degree field of sight．In order to stay alive，they need to see things coming from the sides and from behind．However，without stereoscopic sight，they have difficulty determining how far a danger is．
    With sight both stereoscopic and binocular，humans share with animal hunters the ability to  see from side to side and to accurately determine the distance．If you think it would be great to  have another type of sight，perhaps with hundreds of tiny eyes like many insects do，think again!Each tinv insect eye sees only a tiny part．Besides，what if you needed glasses？Be glad for the  eyesight that you have．

    67．According to the passage，an eye is like a camera because bothA
    A．can record images           B．can imagine objects
    C．provide centered images     D．work at the same height
    68．Stereoscopic sight is a result of havingC
    A．a three-hundred-sixty-degree field of sight
    B．hundreds of eyes，all seeing parts of an image
    C．two eyes close to one another that work together
    D．one eye on either side of the head，each seeing a different image
    69．The underlined word"perceived''in Paragraph 3meansC
    A．set    B．taken    C．seen    D．understood
    70．The author implies that"seeing in stereo"B
    A．is similar to the way cameras work
    B．is an ability humans are fortunate to have
    C．would be better for a wider field of sight
    D．helps people to havelbetter sight than animals．

    7．Running on Empty
    For almost a century，scientists have assumed，tiredness-or exhaustion-in athletes originates in the muscles（肌肉）．Precise explanations have varied，but all have been based on the"Limitations Theory"．In other words，muscles tire because they hit a physical limit； they either run out of fuel or oxygen or they drown in harmful by-products （副产品）．
    In the past few years，however，Timothy Noakes from the University of Cape Town． South Africa，has examined this standard theory．Tiredness，he argues，is caused not by signals springing from overtaxed muscles，but is an emotional response which begins in the brain．The fundamental nature of his new theory is that the brain paces the muscles to keep them well back from the edge of exhaustion．When the brain decides it's time to quit，it creates unbearable muscle tiredness．This"Central Governor"theory remains controversial，but it does-explain many puzzling aspects of athletic performance．
    A recent discovery that Noakes calls the"lactic acid paradox"made him start researching this area seriously．Lactic acid is a by-product of exercise，and the increase of it is often mentioned as a cause of tiredness．But when research subjects exercise in certain conditions created artificially，they become tired even though lactic acid levels remain low．
    Nor has the oxygen content of their blood fallen too low for them to keep going．Obviously，something else was making them tire before they hit either of these physiological limits． Noakes conducted an experiment with seven cyclists．It has long been known that during exercise，the body never uses 100% of the available muscle fibres （纤维）．The amount used varies； but in some tasks such as this cycling test the body calls on about 30%．His team found that as tiredness set in，the electrical activity in cyclist's legs declined-even when they were making a great effort to cycle as fast as they could．
    To Noakes，this was strong evidence that the old theory was wrong．"The cyclists may have felt completely exhausted，"he says，"but their bodies actually had considerable reserves that they could theoretically tap by using a greater amount of the resting fibres．"
    This，he believes； is the proof that the brain is regulating the pace of the workout to hold the well back from the point of extreme tiredness．
    67，Which of the following is supported by the"Limitations Theory"？B
    A．Tiredness is caused by signals from brain．
    B．Athletes feel tired when they use up all their energy．
    C．The body uses 100% of the muscle fibres in exercise．
    D．Athletes become tired though lactic acid levels remain low．
    68．Noakes has found out that．C
    A．muscle fibres control athletes'movements
    B．lactic acid levels remain high in cycling test
    C．mental processes control the symptoms of tiredness
    D．different exercises use different amount of muscle fibres
    69．It is likely that both theories accept that．A
    A．lactic acid is produced in muscles during exercise
    B．the oxygen content in blood may rise after sports
    C．tiredness is a harmful by-product of exercise
    D．the energy in human bodies can be
    70．What is Paragraph 3mainly about？C
    A．The description of a new test．
    B．The explanation of the theory．
    C．The puzzling evidence of a study．
    D．The whole process of the research．

    5．Even as Toyota CEO Akio Toyoda wrapped up a tired appearance before Congress，the head of the world's largest automaker wasn't leaving his problems behind．
    Toyota faces a criminal investigation by federal lawyers in New York．The company is now being investigated．Its US dealerships in difficulty now are facing repairs to potentially millions of customer cars that have been recalled．The company is offering customers money back for rental cars and other expenses．
    Its lawyers are busy preparing to cope with lawsuits．A new hearing will be conducted．And the cost to Toyota's reputation is only now starting．
    Despite back-to-back hearings this  week，left to be said were a better explanation for slow actions to deal with the faults and believable promises that the problems that led to sudden，unintended accelerations will be fixed．
    Toyoda said those changes were being made nearly around the clock，but during three hours of often tense questions and answers he repeated that there was no link to the vehicle's electronic systems．
    Many drivers making complaints against Toyota and the government say their acceleration problems had nothing to do with floor mat interference（油门踏板故障）or sticky gas pedals（刹车）．Outside experts have suggested electronic problems．
    House lawmakers expressed serious criticism on Toyoda，the grandson of the company's founder．
    The National Highway Traffic Safety Administration（NHTSA）is seeking records on Toyota's recalls and is conducting its own review on whether electronics were behind the car faults．NHTSA also continues to look into steering complaints from drivers of the popular Corolla model．
