Passage Three
Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them; our purpose is to prepare them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds, or to continue with one's old system of education without examining it to see whether it is in fact suitable or not.
In many modern countries, it has for some time been fashionable to think that by free education for all—whether rich or poor, clever or stupid—one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider "low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor. We can live without education, but we will die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability, and secondly, we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.
44. Education is______.
A. a purpose
B. a means
C. fashionable
D. the first system
正确答案：B
44．答案为B 此题为细节题。本文主要探讨教育问题。第一句就是主题句，给出了教育的定义。所以答案在第一段的第一句：Education is not an end，but a means to an end。 -
第3题：
For years people have been saying that the railways are dead. We all keep hearing that trains are slow, that they lose money, that they’re dying. But this is far from the true. In these days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they’re cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, a railway takes you from the heart of a city center. It doesn’t hold you up as a car does, in endless traffic jams. And a single train can carry goods which no plane or motorcar could ever do.
Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time? And we are only at the beginning. For we have just entered the age of super-fast trains, trains traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorways we can’t use because we have not enough money to buy the oil and planes we can’t fly in for the same reason.
1. Some people think the railways are dead for many reasons EXCEPT that ____.
A. planes and motorcars have taken the place of trains
B. oil is expensive today
C. trains are slow
D. railways lose money
2. The writers idea seems to be that ______.
A. we can do without railways
B. trains have much in common with motorcars and planes
C. motorcars and planes are not as good as trains
D. trains are as good as motorcars and planes
3. According to the writer, which of the following is NOT the advantage of railways?
A. It is cheaper to travel by train than by plane.
B. Super-fast trains travel even faster than planes.
C. The railway station is usually at the center of a city.
D. A train carries more goods than a motorcar or plane does.
4. The writer thinks that the railways, far from being dead, are very much alive because ___________.
A. we can have a smooth and untroubled journey
B. we’ll not have enough money to fly everywhere
C. we can now travel in super-fast trains
D. all of the above
5. The best title for this passage may be ________.
A. The Best Choice: Train, Motorcar or Plane
B. The Dying Railways
C. Super-fast Trains in the Future
D. Not the End, But the Beginning

第6题：
It's almost impossible to go through life without experiencing some kind of failure.People who do so probably live so cautiously that they go nowhere.Put simply,they’re not real living at all.But,the wonderful thing about failure is that it's entirely up to us to decide how to look at it.We can choose to see failure as"the end of the world,"or as proof of just how inadequate we are.Or,we can look at failure as the incredible learning experience that it often is.Every time we fail at something,we can choose to look for the lesson we're meant to learn.These lessons are very important;they're how we grow,and how we keep from making that same mistake again.Failures stop us only if we let them.Failure can also teach us things about ourselves that we would never have learned otherwise.For instance,failure can help you discover how strong a person you are.Failing at something can help you discover your truest friends,or help you find unexpected motivation to succeed.答案：解析：人的一生几乎不可能不经历某种失败。但是，失败的妙处就在于，完全由我们来决定如何看待它。我们可以选择将失败看作是“世界末日”。或者像以往一样，把它看作令人难以置信的学习经历。每当我们在某件事上失败时，我们会选择寻找应学习的教训。这些教训非常重要；他们教会我们如何成长，如何避免再次犯相同的错误。如果失败阻止我们前进，那么唯一的条件就是我们允许它的发生。失败还可以教会我们认识自己，那是我们在别处永远无法学习到的。例如，失败可以帮助你发现自己的能力。失败可以帮助你发现最真实的朋友，或者帮助你找到预料之外的成功动力。 -

Weight on and off the Earth We are so used to.our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.Because we can feel that things are heavy,we think of "weight"as being a fixed quality in an object,but it is not really fixed at all.If you could take a one-pound packet of butter 4,000 miles out from the earth,it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space?The reason is this:all objects have a natural attraction for all other objects;this is called gravitational attraction.But this power of attraction between two obects gets weaker as they get farther apart.When the butter was at the surface of the earth,it was 4,000 miles from the center.When we took the butter 4,000 miles out,it was 8,000 miles from the center,which is twice the distance.If you double the distance between two objects,their gravitational attraction decreases two times two.If you treble the distance, it gets nine times weaker(three times three)and so on. So this is one of the first things we need to remember that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon?At the distance the puii of the earth is about 4,000 times smaller than it is here on the surface,so we can forget all about the earth-pull on our butter. On the other hand,on the moon there will be an attraction between the butter and the moon,but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.We find it hard to break free from ideas connected with living on the earth because______.
A:it demands too great an effort for us to do so
B:we are too familiar with the way things are to question the ideas
C:we have proved that those ideas are correct
D:we are so sure of ourselves that we never doubt anything on the earth答案：B解析：第一段最后一句表明，1磅重的黄油在离地球表面4000英里处重达0.25磅，第二段第一句也表明在4000英里高空处的物体重量仅为其在地球表面的重量的1/4。由此可推算出，4磅重的茶叶在离地球表面4000英里处重达1磅。
第一段第一句表明，我们之所以不能打破固有思维，是因为我们已经习惯了地球上的生活，也就是说，我们正是因为太过熟悉地球上的事物，才没有去质疑这些固有思维。
第一段第二句表明，物体的重量并非固定不变。第二段解释说，物体的重量源于物体间的引力。也就是说，物体的重量随着物体间引力的改变而改变。
最后一段第三句说明一个物体产生的引力与物体本身的重量有关。最后一段第四句又表明由于本身重量较小，一包黄油产生的引力很有限，相对于月球、地球、太阳等产生的强劲引力来说，比较容易被我们忽略。
本篇文章通篇讲的是重量是由引力产生的，并进一步阐述了物体间引力的变化、物体本身的重量，以及物体间的距离这三者之间的关系，主要讲的还是引力对重量的作用。 -

第12题：
问答题Practice 9 Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war testing whether that nation or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we can not dedicate we can not consecrate we can not hallow — this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion— that we here highly resolve that these dead shall not have died in vain — that this nation, under God, shall have a new birth of freedom — and that government of the people, by the people, for the people, shall not perish from the earth.正确答案：

87年以前,我们的祖先在这大陆上建立了一个新的国家,它孕育于自由之中,并献身于一种理念,即所有人都生来平等。
当前,我们正在从事一场伟大的内战。这场战争对于这个国家,或任何一个有这种主张和这种信仰的国家能否长久生存下去,都是一个考验。此刻,我们在这场战争的一个伟大的战场上集会。我们来到这里,把战场上的一部分土地奉献给在此为这个国家的生存而牺牲了自己生命的人,作为他们的永久安息之所。我们这样做,是十分合情合理的。
可是,就更深一层意义而言,我们其实是不可能奉献这片土地,不可能使它成为圣地,也不可能把它变为人们景仰之所。那些在这里战斗过的勇士,活着的和死去的,已使这块土地神圣化了,远非我们微薄的能力所能改变。我们此时此刻所说的话,世人不大会注意,更不会长久记忆;然而勇士们在这里的所作所为,人们将永志不忘。倒是我们活着的人,应当献身于那些曾经在此作战的人们所英勇推动而尚未完成的工作。我们应该在此献身于摆在我们面前的伟大任务——由于他们的光荣牺牲,我们要更坚定地致力于他们毫无保留地为之作出最后贡献的事业——我们在此不能让他们白白牺牲:要使这个国家在上帝庇佑之下,获得自由的新生,要使这个民有、民治、民享的政府不会从地球上消失。解析： 暂无解析 -
第13题：
B
The world is not only hungry，it is also thirsty for water． this may seem strange to you，since nearly 75% of the earth is covered with water． But about 97% of this water is sea water．Man can only drink and use the other 3% fresh water that comes from rivers，lakes，under-ground and other places． And we cannot even use all of that，because some of this fresh water has been made dirty．
At the moment，this small amount(数量) of fresh water is still enough for us． However，our need for water is getting greater and greater． Only if we take steps to solve this problem now，we can get away from a serious world water shortage later on． The people of the world cannot have an enjoyable life without enough clean water．
On one hand we should stop wasting this little water of ours，on the other hand we should find ways to reuse it，but this has not been done widely．
Today，in most large cities，water is used only once and it then returns to the sea or runs into underground places．lf we can make it clean again，it can be used once more just as if it were fresh from a spring．
But even if large cities reuse its water，we still would not have enough in the future． Where．could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh．
So if we take all these steps，we'll be in no danger of drying up!
( )26． Why does the writer say that the world is thirsty for water?
A． The amount of fresh water is really very small．
B． The people of the world waste too much water．
C． The people of the world have to drink a lot of water every day．
D． There are too many people in the world needing water．

The Need to Remember
Some people say they have no memory at all:"I just can't remember a thing!"But of course we all have a memory.Our memory tells us who we are.Our memory helps us to make use in the present of what we have learnt in the past.
In fact we have different types of memory.For example,our visual memory helps us recall facts and places.Some people have such a strong visual memory that they can remember exactly what they have seen,for example,pages of a book,as a complete picture.
Our verbal（言语的）memory helps us remember words and figures we may have heard but not seen or written:Items of a shopping list,a chemical formula,dates,or a recipe.
With our emotional（情感的）memory, we recall situations or places where we had; strong feelings,perhaps of happiness or unhappiness. We also have special memories for smell,taste, touch and sound,and for performing physical movements.
We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds-enough to remember a telephone number while we dial.Our long-term mem-ory,on the other hand,may store items for a lifetime. Older people in fact have a much biter long-term memory than short-term .They may forget what they have done only a few hours ago,but have the clearest remembrance（记忆）of when they were very young.
Psychologists tell us that we only remember a few facts about our past,and that we invent the rest. It is as though we remember only the outline of a story.We then make up the details. We of-ten do this in the way we want to remember them,usually so that we appear as the heroes of our own past , or maybe victims needing sympathy（同情）.Visual memory helps us recall a place we have been to.
A: Right
B: Wrong
C: Not mentioned答案：A解析：根据文章第二段第二句话可知，视觉记忆可以帮助我们记起事实和地方，故本题表述正确，视觉记忆可以帮我们记起曾经去过的地方。
根据文章第二段最后一句话中的“Some people have such...pages of a book...”可知题干正确，故本题表述正确。
根据文章第三段中的“... words and figures we may have heard but not seen or written...”可知题干表述错误。
根据文章第四段最后一句可知，perform physical movements说的是special memories。因此题干错误。
联系全文，本文主要说的是人的记忆，而未提及动物。
文章倒数第二段对short-term memory和long-term memory作了区分，并未进行重要性的比较。
根据文章最后一段第一句话可知，关于过去我们只记得一部分，剩下的都是自己编造的，故本题表述正确。 -

Some Things We Know About Language
Many things about language are a mystery,and many will always remain so.But some things we do know.
First , we know that all human beings have a language of some sort.There is no race（种族）of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another.Furthermore,in historical times,there has never been a race of men without a language. Second,there is no such thing as a primitive（原始的）language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive.In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood;indeed,the direct contrary has often been stated.Popular ideas of the language of the American Indians will illustrate.Many people have supposed that the Indians communicated in a very primitive system of noises.Study has proved this to be nonsense.There are,or were, hundreds of American Indian languages,and all of them turn out to be very complicated and very old.They are certainly different from the languages that most of us are familiar with,but they are no more primitive than English and Greek.
A third thing we know about language is that all languages are perfectly adequate.That is,each one is a perfect means of expressing the culture of the people who speak the language. Finally,we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time. Change goes on in all aspects of language.Grammatical features change as do speech sounds,and changes in vocabulary are sometimes very extensive and may occur very rapidly.Vocabulary is the least stable part of any language.Which of the following statements is INCORRECT?
A:A language is a means of expressing a particular culture.
B:All languages can well express their respective cultures.
C:American Indian languages are as complex as English.
D:Some languages are better than others.答案：D解析：根据第二段第一句中的“First"，第三段第一句中的“second，第五段第一句中的“Athird thing"，以及第六段第一句中“Finally”可知，作者主要从四个方面来淦释语言的特征。
根据第三段最后一句可知，所有已知的语言无不经过了数万年的充分发展。
第四段第一句中的“This”指的就是第三段所诊释的内容，再结合第三段第一句" Second , there is no such thing as a primitive language.”可知，A项正确。
由第五段可知，A、B两项表述正确。根据第四段最后一句可知，作者认为不同的语言没有发展水平上的差别，美国的印第安语和英语一样复杂，故C项表述正确，D项表述不正确。
根据第六段最后一句可知，词汇是所有语言中最不稳定的部分，即它最容易发生变化。 -
第20题：
The water we drink and use is running short in the world.We all have to learn how to stop wasting our limited water.One of the steps we should take is to find ways of reusing it.Experiments have already been done in this field.
Today in most large cities,fresh water is used only once,then it runs into waste system.But it is possible to pipe the used water to a purifying factory.There it can be filtered and treated with chemicals so that it can be used again,just as it were fresh from a spring.
But even if every large city purified and reused its water,we still would not have enough.Then we could turn to the oceans.All we’d have to do to make use of the seawater on earth is to get rid of the salt.This process is called desalinization,and it is already in use in many parts of the world.
