A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔爐) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.
Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(處理) in the sky!
When the star begins to die ______.
A. there is no fuel left in it B. its outer layer goes into space first
C. a huge explosion will happen D. it doesn’t give off light any longer
Which of the following doesn’t help produce a black hole?
A. The gravity inside the star is very strong. B. The light can’t go out of the star.
C. The star becomes smaller and smaller D. The dying star shines very brightly.
The black hole ______.
A. continues becoming smaller and smaller all the time
B. goes into another universe and becomes a white hole
C. can pull in everything we know of in the world
D. will appear at another place at a different time
What’s the best title for this passage?
A. A New Scientific Discovery: Black Holes
B. How Do Black Holes Come Into Being?
C. What Are Black Holes?
D. Travel Through A Black Hole
“A lot of learning comes through play,” says Mardy McGarry, 52, who has been a special education teacher for 28 years. But her students were too often left out. She had seen the wood chips and sand of traditional playgrounds stop wheelchairs dead in their tracks. When she wanted to build a playground for children with special needs,she knew it wouldn’t take long to develop interest in it around the small fishing village. But she never expected that 2,800 people — a third of the town—would all be willing to make a great effort to bring her vision to life.
McGarry started doing some research into play equipment and contacting design companies and she also found a piece of land available. When the city council(市議會(huì)) agreed to set aside an area for a playground, she also asked physical and professional therapists(治療專家) for their investment. And she turned to her friend, Sue, for help. “Neither of us is good at maths, which is why $450,000 didn’t sound like a lot of money,” McGarry says of the initial estimate.
Her Kiwanis Club came through with $7,000,and that’s when the grassroots movement really got started. One woman gave $25,000 and had her company match it. Soon, smaller businesses were joining in. There was a silent effort to collect money. The local Pieper Family Foundation offered to donate half of the remaining $170,000. All McGarry needed was 500 volunteers to work six 12-hour days.
On September 16, 2008, the first day of construction, they came. Two women heard about the project on the way to work and took the day off to help. A couple in their 80s operated their tractors. Ten-year-olds cleared up the mess. “None of them was paid. It was truly an amazing week,” says McGarry. Only three building managers were paid. Volunteers with “building experience” became coordinators(協(xié)調(diào)人); those who could operate power tools formed a separate group. One team served meals donated from local restaurants and churches, and another organized activities for the children of volunteers.
Today, Possibility Playground is one of the most popular destinations in Ozaukee County. All children, including the ones with special needs, play shoulder to shoulder. “Some playgrounds have special equipment in a different section. Here, you see all the kids in the same playground, all having fun.”
It’s exactly what McGarry imagined. “People used to ask, ‘Why do you want to build a playground just for children with disabilities?” She says, “It’s only when you build a playground for children with disabilities that you build one for all children.”
It didn’t occur to Mardy McGarry that __________.
A. her plan would soon draw the interest of people in the small village
B. so many people would volunteer to help her realize her dream
C. she would meet with so many difficulties in raising funds
D. the playground would be the most popular destination in Ozaukee County
We can learn from the fourth paragraph that __________.
A. the playground was finished in September 2008
B. everything was well prepared, apart from the volunteers
C. everyone worked unpaid, except for three building managers
D. the playground is so popular that it is overcrowded all the time
It can be inferred from the text that __________.
A. Mardy McGarry is a famous architect in the small town
B. Sue was forced to join in the project because of her son
C. people always ignore the real needs of disabled children
D. Mardy McGarry’s vision has been successfully accomplished at last
What would be the best title for this text?
A. Mardy McGarry: A Woman with Great Determination.
B. Cooperation: The Greatest Power in Overcoming Any Difficulty.
C. Show Real Concern for Poor Disabled Children.
D. Make it Matter to Build a Playground for Disabled Children.

A few days ago I asked my sons’ governess(女家庭教師)Julia to come into my study. “Be seated, Julia, ”I said, “Let’s settle our accounts. I guess you most likely need some money, but maybe you’re too polite to mention it. Now then, we agreed on thirty dollars a month...”
“Forty.”
“No, thirty. I made a note of it. I always pay our governess thirty. Well, um, you’ve been here two months, so...”
“Two months and five days.”
“Exactly two months. I made a special note of it. That means you have sixty dollars coming to you. Take off nine Sundays... you know you didn’t work with Tom on Sundays, you only took walks. And three holidays... ”Julia was biting her finger nail nervously, her face red, but - not a word.
“Three holidays, therefore take off twelve dollars. Four days Tom was sick and there were no lessons, as you were occupied only with Dick. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven - nineteen. Take nineteen off ... that leaves. hmm.... forty one dollars. Correct?”
Julia’s left eye reddened with tears welling up. Her chin trembled; she coughed nervously and blew her nose, but - still not a word.
“Around New Year’s Day you broke a teacup and a saucer; take off two dollars. The cup cost more, it was a treasure of the family, but- forget it. When didn’t I take a loss! Then, due to your neglect (疏忽), Tom climbed a tree and tore his jacket; take away ten. Also due to your carelessness the maid stole Dick’s shoes. You ought to watch everything! You get paid for it. So, that means five more dollars off. The tenth of January I gave ten dollars.”
“You didn’t. ”sobbed Julia.
“But I made a note of it.”
“Well... if you say so.”
“Take twenty seven from forty one -that leaves fourteen.”
Both her eyes were filled with tears. Beads of sweat stood on the thin pretty little nose. Poor girl!
“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife. Three dollars, nothing more.”
“Really? You see now, and I didn’t know that! Take three from fourteen.. leaves eleven. Here’s your money, my dear. Three, three, three, one and one. Here it is !”
I handed her eleven dollars. She took them and pocketed them.
“Merci (法語: 謝謝),”she whispered.
I jumped to my feet and started pacing the room. I was overcome with anger. “For what, this - ‘merci’?” I asked.
“For the money. ”
“But you know I’ve cheated you - robbed you ! I have actually stolen from you ! Why this‘merci’?”
“In my other places they didn’t give me anything at all.”
“They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you... I m going to give you all the eighty dollars! Here they are in the envelope all ready for you... Is it really possible to be so spineless (懦弱)?Why didn’t you protest? Why were you silent? Is it possible in this world to be without teeth and claws(爪)—to be such a fool?”
Embarrassed, she smiled. And I could read her expression,“It is possible.”
I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars. She murmured her little“merci”several times and went out. I looked after her and thought,“How easy it is to crush the weak in this world !”

WHEN an NBA player is young he thinks he can win the championship by himself. It is only later when he has aged and been through many battles that he learns an important lesson: there is no "I" in "team".
There is no better example of the value of teamwork than the Boston Celtics. Paul Pierce, Ray Allen and Kevin Garnett were all superstars on three different teams. Yet, none of them had any titles to show for it. Then, last season, they decided to sacrifice money and individual statistics to play together. Garnett and Allen joined Pierce on the Celtics and changed the NBA in the process.
It started in simple ways. Garnett and Allen are two of the most intense athletes in the world. They treat every second of every practice like it is the NBA championship. If you want to play alongside them then you will have to do the same. So, the young guys on the Celtics started giving their full effort too.
Pierce had been the star of the Celtics for many years. He used to shoot the ball many times a game. But with the addition of Allen and Garnett he shot less and focused on defense. His selflessness showed the young players that doing what made the team better was the only thing that mattered.
When the Celtics were winning and the game was almost over, Garnett, Pierce and Allen would come out of the game. But they wouldn’t just sit on the bench. Instead, they stood and cheered and screamed for their teammates. They wanted to support their friends and teammates.
Now, the guys who don't play know they can still affect the game by cheering so they scream and cheer when Garnett, Allen and Pierce are playing. The Celtics have developed a strong relationship. They are more than just teammates. They are brothers.
The result: the Boston Celtics won the 2008 NBA championship and are considered the favorites to win the Eastern Conference championship again this year.
There is a saying that goes, “A successful team beats with one heart.” If that is the case, the Celtics may have the biggest heart in the NBA.

D. Paul Pierce, Ray Allen and Kevin Garnett had won NBA championships before they joined hands.
68. What does this sentence “there is no ‘I’ in ‘team’.” mean in Paragraph 1?
A. “I” will be missing once "I" am on the court.
B. “I” work so hard in a team that “I” will forget who “I” am.
