Early people had very little effect on the environment. They lived in caves in very small “clan” groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which mean that they didn’t stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖)before the clan returned for the next season..
As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually, people tamed(馴養(yǎng))wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so then began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also give people more free time. So art ,dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.
小題1:Early tribes didn’t have much effect on animal population because_____
A .they kept animals for themselves         B they ate only vegetables
C they loved animals                     D they killed only enough for food
小題2:The main purpose for small clans to join together was_____
A to hurt animals                         B to seek safety

A early people moved to new places looking for new sources of food
B modern civilization began when people started to live together in big groups
C modern advancements are always good for the environment
D people began to exchange goods because they didn’t have enough money
小題4:It can be concluded from the passage that_____
A human progress has brought civilization to the society
B civilization has improved traditional forms of work
C early people understood environmental protection
D our environment has been affected by human progress

It is sometimes said that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects (UFO). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report.
Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night.
“It wasn’t the moon ”, was the reply.
They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn’t smoke because it didn’t change its shape. It was moving in a regular way. That is to say, it didn’t go suddenly faster or more slowly, and it didn’t go higher or lower. So the two men decided that there must be men in it.
After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness.
When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast.
On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken?
小題1: UFOs are _____.
A.flying high up in the skyB.strange flying objects
C.difficult to believeD.very interested
小題2: A UFO was seen one night _____.
A.when they were walking across a yard to Burdens’ room
B.while they were looking at the light
C.when Burdens noticed the moon appearing strange
D.while they were having dinner
小題3:The UFO moved _______.
A.regularlyB.in a changeable wayC.slowlyD.fast
小題4: The UFO looked like _____ .
A.smokeB.a(chǎn) large plateC.lightD.a(chǎn) jumping object
小題5:The UFO was seen ______ .
A.by Burdens and his friendB.brighter in the darkness

When a group of children politely stop a conversation with you, saying: “We have to go to work now,” you’re left feeling surprised and certainly uneasy. After all, this is the 1990s and the idea of children working is just unthinkable. That is, until you are told that they are all pupils of stage schools, and that the “work” they go off to is to go on the stage in a theatre.
  Stage schools often act as agencies(代理機(jī)構(gòu))to supply children for stage and television work. More worthy of the name “stage school” are those few places where children attend full time, with a training for the theatre and a general education.
  A visit to such schools will leave you in no doubt that the children enjoy themselves. After all, what lively children wouldn’t settle for spending only half the day doing ordinary school work, and acting, singing or dancing their way through the other half of the day?
 Then of course there are times for the children to make a name and make a little money in some big shows. Some stage schools give their children too much professional work at such a young age. But the law is very tight on the amount they can do. Those under 13 are limited to 40 days in the year; those over 13 to 80 days.
 The schools themselves admit that not all children will be successful in the profession for which they are being trained. So what happens to those who don’t make it? While all the leading schools say they place great importance on children getting good study results, the facts seem to suggest this is not always the case.
 小題1:People would stop feeling uneasy when realizing that the children they’re talking to________.
   
A.a(chǎn)ttend a stage school    B.a(chǎn)re going to the theatre
  
C.have got some work to do   D.love singing and dancing
  小題2: In the writer’s opinion, a good stage school should ________.
   
A.produce star performers
  
B.help pupils improve their study skills
  
C.train pupils in language and performing arts
  
D.provide a general education and stage training.
 小題3:“Professional work” as used in the text means ________.
   
A.ordinary school work     B.money-making performances
  
C.stage training at school   D.a(chǎn)cting, singing or dancing after class
 小題4: Which of the following best describes how the writer feels about stage schools?
   
A.He thinks highly of what they have to offer.    
  
B.He favours an early start in the training of performing arts.
  
C.He feels uncomfortable about children putting on night shows.
  
D.He doubts the standard of ordinary education they have reached.

Dearest Mom and Dad,
I'm afraid I have some very bad news for you. I have been very naughty and the school principal is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.
The trouble started last night when I was smoking a cigarette in bed. This is against the rules, of course. We are not supposed to smoke at all.
As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away.
Unfortunately, the cigarette fell into the waste-paper basket, which caught fire. There was a curtain near the waste-paper basket which caught fire, too. Soon the whole room was burning.
The principal phoned for the fire department. The school is a long way from the town and by the time the fire department arrived, the whole school was in flames. Many of the girls are in the hospital.
The principal says the fire was my fault and you must pay for the damage. She will send you a bill for about a million dollars.
I am very sorry about this.
Much love, Sarah

High school dropouts(輟學(xué)者)earn an average of $ 9,000 less per year than graduates. Now a new study dispels a common belief why they quit. It’s much more basic than flunking out(不及格).
Society tends to think of high school dropouts as kids who just can’t cut it. They are lazy,and perhaps not too bright.So researchers were surprised when they asked more than 450 kids who quit school about why they left.
“The vast majority actually had passing grades and they were confident that they could have graduated from high school.” John Bridgeland, the executive researcher said. About 1 million teens leave school each year. Only about half of African-American and Hispanic(美籍西班牙的)student will receive a diploma(證書(shū)),and actually all dropouts come to regret their decision. So, if failing grades don’t explain why these kids quit, what does? Again,John Bridgeland:"The most dependable finding was that they were bored.” “They found classes uninteresting; they weren’t inspired or motivated. They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations.”
The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit. In the US,only one state,New Mexico,has a law requiring teenagers to stay in high school until they graduate. Only four states: California, Tennessee, Texas and Utah, plus the District of Columbia, require school attendance until age 18, no exceptions, another researcher,says raising the compulsory(義務(wù)的)attendance age may be one way to keep more kids in school.
 “As these dropouts look back,they realize they’ve made a mistake. And anything that sort of gives these people an extra push to stick it out and it through to the end, is probably helpful measure.”
New Hampshire may be the next state to raise its school attendance age to 18. But critics say that forcing the students unwilling to continue their studies to stay in school misses the point-the need for reform. It's been called for to reinvent high school education to make it more challenging and relevant, and to ensure that kids who do stick it out receive a diploma that actually means something.  
小題1:Most high school students drop out of' school because__.
A.they have failing gradesB.they take no interest in classes
C.they are discriminated againstD.they are lazy and not intelligent
小題2:Acceding to the passage,which state has a law requiring school attendance until they graduate?
A.New HampshireB.UtahC.New MexicoD.The District of Columbia
小題3:The underlined words “stick it out” probably means“__”.
A.complete schoolingB.solve the problem
C.love having classesD.believe in themselves
小題4:From the passage,we can infer the following EXCEPT that_.
A.the grades of most dropouts at school were acceptable
B.a(chǎn)bout 500, 000 high school dropouts are black and Spanish
C.classes don't appeal to dropouts
D.on average dropouts cannot get good jobs

Superconducting Materials
The stone age, The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Welcome to the age of superstuff(超級(jí)材料). Material science -- once the least sexy technology – is bursting with new, practical discoveries led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the picture: from house and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science.
The key to the new materials is researchers’ increasing ability to manipulate substances at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the microscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and never rust or corrode.
A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites – plastic reinforced with fibers of graphite or other compounds – made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantryman’s life by deflecting two bullets in the Grenada invasion.
Some advanced materials are old standard with a new twist. The newest fiberoptic(光學(xué)纖維的) cable that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane.
But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.
小題1:How many new materials are mentioned in this passage?
A Two      B Three    C Four    D Five
小題2:Why does the author mention genetic engineering and computer science?
A To compare them with the new materials.
B To show the significance of the new materials on the future world.
C To compare the new materials to them.
D To explain his view point.
小題3:Why is transition difficult?
A Because transition requires money and time.
B Because many manufacturers are unwilling to change their equipment.
C Because research on new materials is very difficult.
D Because it takes 10 years.
小題4:Where lies success of a country in the New Age of superstuff?
A It lies in research.      B It lies in investment.
C It lies in innovation.    D It lies in application.

It is difficult for parents of nearly every family to teach their children to be responsible for housework, but with one of the following suggestions, you really can get your children to help at home.
If you give your children the impression that they_____________________, then they will regard themselves as unfit or unable persons. Unless children believe they can succeed, they will never become totally independent (獨(dú)立).     
My daughter Carla’s fifth-grade teacher made every child in her class feel special. When students received less than a perfect test score, she would point out what they had mastered and declared firmly they could learn what they had missed.
You can use the same technique when you evaluate (評(píng)價(jià))your child’s work at home. Don’t always scold and give lots of praise instead. Talk about what he has done right, not about what he hasn’t done. If your child completes a difficult task, reward him with a Sunday trip or a ball game with Dad.
Learning is a process (過(guò)程)of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.
1.What’s the best title of the passage?    
2.Which sentence in the passage is the closest in meaning to the following one?
The process of learning is full of trying and failing ,and after trying again and again ,one will succeed.
3.Please fill in the blank in the passage with proper words or phrases to complete the sentence.(within ten words)

The average person learns most of the 30 000~40 000 words whose meanings he or she recognizes by hearing them or getting familiar with them in the context or simply absorbing them without conscious(意識(shí)到的) effort. The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks. There are relatively few words that we learn permanently(永久的)by purposefully referring to dictionaries or keeping word lists. However, even those extra few are of value, and no one will make a mistake by working on developing a larger vocabulary. Here are some suggestions of how to do it.
Read plenty of good books. When you come across a new word, or a new meaning of an old word, stop and see if you can understand it from its context. If you can't, and if you can manage without interrupting the thought of the book too much, look it up in a dictionary or ask somebody and then repeat its meaning to yourself a couple of times. If you are really conscientious(認(rèn)真的), write the word and its meaning in a personal vocabulary list — preferably using it in a sentence, or you can keep a special vocabulary notebook. Go over the list from time to time. Further, try to use a new word in writing or conversation a few times over the next several days.
Listen to good talks and be alert to new words you hear or to new meanings of words you already know. Then treat them just as you treat the new words you read.
Learn and be alert to the parts of words: prefixes, suffixes and roots. Knowing them enables you to make intelligent guesses about the meaning of words.
If you are studying a foreign language, be alert to words in that language which relate to words in English. English has inherited(繼承) or borrowed much of its vocabulary of 500 000~600 000 words from Latin, Greek, French, Spanish and German.
小題1:When you meet a new word in reading, what should you do?
A.Guess its meaning. B.Ask somebody.
C.Look it up in a dictionary. D.All of the above.
小題2:According to this passage, the best way to build a good vocabulary is _______.
A.to remember a lotB.to read a great deal
C.to take part in a lot of good talksD.both B and C
小題3:The phrase “be alert to” in the third paragraph may best be replaced by “_______”.
A.look atB.pay attention to
C.write downD.learn by heart
小題4:In the fourth paragraph, the word “them” refers to _______.
A.the parts of wordsB.prefixes
C.suffixesD.roots
