Millions of years ago dinosaurs (恐龍) lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to cat. This must be one reason why dinosaurs died out.
We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don’t know about yet. Scientists are trying to make more discoveries about dinosaurs.
Dinosaurs were of many sizes and shapes (形狀).  Some were as small as chickens, while some were about 90 feet long.
There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal’s footprints (足跡) that fight did take place.

Once upon a time, a man was walking on a mountain when he found an incredible cave with all kinds of treasure inside it. So he gave up his job, his home, and his friends, and spent all his time guarding the cave.
He was so dedicated to it that he hardly ate or drank, and before long he fell ill. One day, when he could hardly move at all, he decided to share the treasure.
He crawled into the cave to get a handful of jewels, but discovered, to his horror, that it was empty except for a small emerald (綠寶石). The man took it and gave it to the first person to come by, a woman.
Then an old man came by. “What bad luck!” the man said. “Just a moment ago I gave a woman the last of the treasure I was guarding.”
“Are you sure there is nothing left?” the old man asked.
The man took him into the cave, where they found a chest with jewels and some bags of gold. The man was shocked, and the old man explained to him, “At last! At last! At last someone has broken the spell of this cave. This is the Cave of Treasure, and you’re the first to have passed its great test. Many have dedicated their lives to this cave, only to end up realizing there was nothing here …”
“And why does this happen?” the man asked.
“This magic cave has only as many riches as your own heart. When someone discovers it, the cave fills with the treasure they bring with them, but later, when they have devoted themselves to guarding the treasure, their hearts become empty, as does the cave. The only way to fill it is by filling your heart with all that is good, as you did by giving the woman that last jewel.”
From that day on, the man understood that it was better to share than to keep. Thanks to the cave and the old man, he became noble and generous.
【小題1】Why did the man give up his job, home and friends?

A.Because he possessed a variety of treasure.
B.Because he devoted himself to a great test.
C.Because he had to guard the treasure cave.
D.Because he wanted to find the treasure cave.
【小題2】 What did the man find when he showed his cave to the old man?
A.All kinds of treasure. B.A chest with jewels and gold.
C.A small emerald. D.A handful of jewels.
【小題3】What do we learn about the people who dedicated their lives to the cave before?
A.They all found the cave empty at last.
B.The old man freed them from its spell.
C.They all filled the cave with the treasure they had.
D.They thought it was better to share than to enjoy the treasure alone.
【小題4】What can we learn from the text?
A.Different people have different views.
B.Treasure only belongs to those who possess it.
C.Some people never learn what is really valuable.
D.Purely material things cannot make us truly wealthy.

For most of my 15 years, my father usually said very little to my mother and me. He preferred reading the newspaper or watching football matches on television to talking to his family.
Everything changed one morning. As soon as I came downstairs to breakfast, I could see that he wasn’t his usual reserved (緘默的) self. “Can’t wait! FIFA World Cup! Big match! Must see!”    I quickly figured out what all the excitement was about: Dad is a big football fan.
I had never been interested in football, but Dad’s excitement that morning made me more and more curious. I had to find out why this sport was making my normally reserved father act like a five-year-old on his first trip to Disneyland.
Dad decided that we should all eat at a little German restaurant so that we could watch the World Cup while eating. Secretly, I think he was hoping to turn Mum and me into football fans.
The match started a few minutes after we entered the restaurant. As I was eating my meal, a loud noise came from the television. Surprised, I looked up at the TV: “Why is that man jumping up and down?” Dad patiently explained: “That’s Papa Bouba Diop, my son. It’s normal for them to jump up and down after they’ve scored.”
Dad explained almost everything to me. His monosyllabic (單音節(jié)的) answers were a thing of the past. I loved the new Dad! I watched the rest of the match, becoming more and more interested. When I told my father that I planned to watch more matches with him, he smiled and gave me a wink (眨眼). At long last we had something in common.
Football has really helped Dad and me get closer and form a stronger relationship with each other. Who says football is only about 22 men running after a silly ball?

One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. Fear-producing TV and computer games are leading to serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.
Each of us has a place in nature we go sometimes, even if it was torn down. We cannot be the last generation to have that place. At this rate, kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes. “If the decline in park use continues across North America, who will defend parks against encroachment(蠶食)?” asks Richard Louv, author of Last Child in the woods.
Without having a nature experience, kids can turn out just fine, but they are missing out a huge enrichment to their lives. Experts predict modern kids will have poorer health than their parents—and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component and that play in nature fosters(培養(yǎng))leadership by the smartest, not by the toughest, Even a tiny outdoor experience can create wonder in a child. The three-year-old turning over his first rock realizes be is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.
Kids are not to blame. They are over-protected and frightened. It is dangerous out there from time to time but repetitive stress from computers is replacing breaking an arm as a childhood rite(儀式)of passage.
Everyone, from developers, to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that strengthen love, respect and need for the landscapes. As parents, we should devote some of our energy to taking our kids into nature. This could yet be our greatest cause.
【小題1】 According to the author, what causes kids’ getting lost in a “sea of technology”?

A.The wild places of the world
B.The kids themselves
C.The outdoor activities
D.TV and computer games
【小題2】The underlined words “that place” in paragraph 2 can most probably refer to _______.                  
A.a(chǎn) hill B.a(chǎn) library C.a(chǎn) bar D.a(chǎn) classroom
【小題3】According to the author, children’s breaking an arm is _______.
A.the fault on the part of their parents
B.the natural experience in their growing up
C.the result of their own carelessness in play
D.the effect of stress from computer
【小題4】What’s the author’s opinion on children’s experiencing the nature world?
A.It leads to children’s escape from school.
B.It’s helpful only in a limited way.
C.It helps develop children from all sides.
D.It increases the chance of getting injured.

I began to grow up that winter night when my parents and I were returning from my aunt's house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see-—the strange and magical places I had known only from books and pictures. The country I was leaving never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to "the hard times."
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: almost all common troubles eventually go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.
【小題1】How did the author get to know America?

A.From her relatives. B.From her mother.
C.From books and pictures. D.From radio programs.
【小題2】Upon leaving for America the author felt_______.
A.confused B.excited

【小題3】For the first two years in New York, the author _________.
A.often lost her way
B.did not think about her future
C.studied in three different schools
D.got on well with her stepfather
【小題4】What can we learn about the author from Paragraph 4?
A. She worked as a translator.
B. She attended a lot of job interviews
C. She paid telephone bills for her family
D She helped her family with her English.

It is nice to know what the weather will be like when we plan a trip. Do you know anything about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back.
It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.
Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand — no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why?
A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.
In this example studying tree rings uncovered an exciting fact about the history of man.
【小題1】We can find out the weather of five years ago by counting the rings of a tree trunk ____.

A.from the left to the right
B.from the right to the left
C.from the inside to the outside
D.from the outside to the inside
【小題2】If the ring was far from the others, we can conclude that the weather of that year was ______.
A.bad B.sunny C.favorable D.rainy
【小題3】By studying the rings of dead trees in an area of New Mexico, the scientist found _______.
A.why the people had to leave
B.where the people had to go
C.what the people had to eat
D.how the people left
【小題4】The ancient people usually lived where there were plenty of trees mainly because ______.
A.trees provided an exact record of weather for research
B.trees could supply them with fruit and food to live on
C.trees could supply them with shades
D.trees were materials for fires and buildings
【小題5】By giving the example of an area of New Mexico, the author tries to prove        .
A.trees can’t live in the area without population
B.that studying trees is important for the history of man and weather.
C.what the real relation is between tree rings and the history of man and weather
D.the history of man is important for the history of trees

It is widely known that any English conversation begins with The Weather. Such a fixation with the weather finds expression in Dr.Johnson’s famous comment that “When two English meet, their first talk is of weather.” Though Johnson’s observation is as accurate now as it was over two hundred years ago, most commentators fail to come up with a convincing explanation for this English weather-speak.
Bill Bryson, for ezample, concludes that,as the English weather is not at all exciting,the obsession with it can hardly be understood. He argues that”To an outsider,the most striking thing about the English weather is that there is not very much of it.” Simply, the reason is that the unusual and unpredictable weather is almost unknown in the British Isles.
Jeremy Paxman, however, disagrees with Bryson, arguing that the English weather is by nature attractive. Bryson is wrong, he says,because the English preference for the weather has nothing to do with the natural phenomena.”The interest is less in the phenomena themselves, but in uncertainty.” According to him, the weather in England is very changeable and uncertain and it attracts the English as well as the outsider.
Bryson and Paxman stand for common misconceptions about the weather-speak among the English. Both commentators, somehow, are missing the point. The English weather conversation is not really about the weather at all. English weather-speak is a system of signs ,which is developed to help the speakers overcome the natural reserve and actually talk to each other. Everyone knows conversations starting with weather-speak are not requests for weather data. Rather, they are routine greetings,conversation starters or the blank”fillers”, In other words, English weather-speak is a means of social bonding.
【小題1】The author mentions Dr.Johnson’s comment to show that________.

A.most commentators agree with Dr.Johnson
B.Dr.Johnson is famous for his weather observation
C.the comment was accurate two hundred years ago
D.English conversations usually start with the weather
【小題2】What doe s the underlined word”obsession” most probably refer to?
A.A social trend.B.An emotional state.
C.A historical concept.D.An unknown phenomenon.
【小題3】According to the passage,Jeremy Paxman believes that________.
A.Bill Bryson has little knowledge of the weather
B.there is nothing special about the English weather
C.the English weather attracts people to the British Isles
D.English people talk about the weather for its unccrtainty
【小題4】What is the author’s main purpose of writing the passage?
A.To explain what English weather-speak is about.
B.To analyse misconceptions about the English weather.
C.To find fault with both Bill Bryson and Jeremy Paxman.
D.To convince people that the English weather is changeable.

Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.
“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”
Astronomers---scientists who study stars and planets----have been complaining about this problem for decades.They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.
There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds,bats frogs,snakes,etc. For example,outdoor lighting severely affects migrating(遷徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”
Countless more animals casualties(傷亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings,but some scientists think it can be harmful for humans,too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.
Emerald Valley is only one community that is becoming aware of the negative effects of hight pollution. For years, Flagstaff,Arizona, has enforced lighting regulations in its city in order to help astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.
【小題1】It happened last night that __________ .

A.the city light show attracted many people

It’s generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.
It’s undeniable that behavior comes from our inner dispositions(性情), but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by observing our own behavior. We can be strangers to ourselves. If we knew our own minds, why should we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually, we often need to look to our behavior to figure out who we are.
Moreover, we don’t just use our behavior to learn about our particular types of character --- we infer characters that weren’t there before. Our behavior is often shaped by little pressures around us, which we fail to recognize. Maybe we recycle because our wives and neighbors would disapprove if we didn’t. Maybe we buy lattes in order to impress the people around us. We should not mistakenly believe that we always behave as a result of some inner disposition.
Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance(符合)with their true desires. Therefore, we should all bear in mind Kurt Vonnegut’s advice: “We are what we pretend to be, so we must be careful about what we pretend to be.”
【小題1】According to the passage, personalities and attitudes are commonly believed to _______.

A.determine one’s behaviorB.reflect one’s taste
C.influence one’s surroundingsD.result from one’s habits
【小題2】Which of the following would Daryl Bern most probably agree with?
A.The return of a wallet can indicate one’s honesty.
B.A kind person will offer his seat to the old.
C.One recycles plastics to protect the environment.
D.One buys latte out of love of coffee.
【小題3】What can be inferred from the underlined sentence in the passage?
A.We fail to realize our inner dispositions.
B.We can be influenced by outside pressures.
C.Our behavior is the result of our true desires.
D.Our characters can shape our social relationships.
【小題4】What does the author mainly discusses in the passage?
A.Personalities and attitudes.B.Preferences and habits.
C.Behavior and personalities.D.Attitudes and preferences.
