More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons．Exercise strengthens the heart muscle，reduces blood pressure and help to prevent muscles from changing into fat．Physical exercise is just as important for children．
Exercise and food affect growing speed in young lab animals．Baby mice start running as soon as they are big enough to use an exercise wheel in their cage．If they get extra food and run a lot，they will grow as much as 1.5 times bigger than normal．
The same differences in growing speed might be found between active and inactive children．Physical exercise helps active children grow faster than inactive children．One experiment shows that the brains of the mice that had enough exercise weighed about 3％more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise．
The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected．
The good effects of physical exercise are not limited to children and middle-aged people．Exercise continues to be an important part of our lives after we grow old．For example，people over 50 years old begin to lose calcium(钙) from their bones，which get weaker and can break easily．Physical exercise，however，helps to strengthen the bones and to prevent them from losing calcium．Of course，old people can take medicines to prevent themselves from suffering from losing calcium．But the medicines they take increase the chance of developing some kind of cancer(癌)．So physical exercise is a much safer treatment(治疗)．From the passage we know that .
| A．mice need to eat more and exercise more |
| B．children need more exercise than other people |
| C．old people like to take medicine to treat their illnesses |
| D．middle-aged people are easy to get fat |
Active children than inactive children．
| A．enjoy walking more |
| B．are cleverer and healthier |
| C．are stronger but more foolish |
| D．are cleverer but weaker |
Why are the bones of old people easy to break according to the passage?
| A．Because they are easy to become ill． |
| B．Because they eat less than other people． |
| C．Because they have less exercise than other people． |
| D．there is less calcium in their bones than in those of other people． |
The passage tells people that .
| A．only middle-aged persons can benefit from physical exercise |
| B．physical exercise can do good to both the middle-aged and children |
| C．people of different ages can all benefit from physical exercise |
| D．physical exercise is the safest treatment for losing calcium |
“OK,”I said to my daughter as she bent over her afternoon bowl of rice. “What’s going on with you and your friend J.?” J. is the leader of a group of third-graders at her camp-- a position Lucy herself occupied the previous summer. Now she’s the one on the outs. and every day at snack time, she tells me all about it, while I offer the unhelpful advice all summer long.
“She’s fond of giving orders, ”Lucy complained. “She’s turning everyone against me. She’s mean. And she’s fat.” “Excuse me,” I said, struggling for calm. “What did you just said?” “She’s fat.” Lucy mumbled(含糊地说).“We’re going upstairs,” I said, my voice cold. “We’re going to discuss this.” And up we went. I’d spent the nine years since her birth getting ready for this day, the day we’d have the conversation about this horrible word. I knew exactly what to say to the girl on the receiving end of the teasing, but in all of my imaginings, it never once occurred to me that my daughter would be the one who used the F word-Fat.
My daughter sat on her bed, and I sat beside her. “How would you feel if someone made fun of you for something that wasn’t your fault?” I began. “She could stop eating so much,” Lucy mumbled, mouthing the simple advice a thousand doctors have given overweight women for years.
“It’s not always that easy,” I said . “Everyone’s different in terms of how they treat food.” Lucy looked at me, waiting for me to go on. I opened my mouth, then closed it. Should I tell her that, in teasing a woman’s weight, she’s joined the long tradition of critics? Should I tell her I didn’t cry when someone posted my picture and commented , “I’m sorry, but aren’t authors who write books marketed to young women supposed to be pretty?”
Does she need to know, now, that life isn’t fair ? I feel her eyes on me, waiting for an answer I don’t have. Words are my tools. Stories are my job. It’s possible she’ll remember what I say forever, and I have no idea what to say.
So I tell her the only thing I can come up with that is absolutely true. I say to my daughter, “I love you, and there is nothing you could ever do to make me not love you. But I’m disappointed in you right now. There are plenty of reasons for not liking someone. What she looks like isn’t one of them. ”
Lucy nods, tears on her cheeks. “I won’t say that again,” she tells me, and I pull her close, pressing my nose against her hair. As we sit there together, I pray for her to be smart and strong. I pray for her to find friends, work she loves, a partner who loves her. And still, always, I pray that she will never struggle as I’ve struggled, that weight will never be her cross to bear. She may not be able to use the word in our home, but I can use in my head. I pray that she will never get fat.The underlined sentence in Paragraph 1 indicates that Lucy ______.

I lost my sight when I was four years old by falling off a box car in a freight yard in Atlantic City and landing on my head. Now I am thirty two. I can vaguely remember the brightness of sunshine and what color red is. It would be wonderful to see again, but a calamity can do strange things to people. It occurred to me the other day that I might not have come to love life as I do if I hadn't been blind. I believe in life now. I am not so sure that I would have believed in it so deeply, otherwise. I don't mean that I would prefer to go without my eyes. I simply mean that the loss of them made me appreciate the more what I had left.
Life, I believe, asks a continuous series of adjustments to reality. The more readily a person is able to make these adjustments, the more meaningful his own private world becomes. The adjustment is never easy. I was bewildered and afraid. But I was lucky. My parents and my teachers saw something in me--a potential to live, you might call it--which I didn't see, and they made me want to fight it out with blindness.
The hardest lesson I had to learn was to believe in myself. That was basic. If I hadn't been able to do that, I would have collapsed and become a chair rocker on the front porch for the rest of my life. When I say belief in myself I am not talking about simply the kind of self confidence that helps me down an unfamiliar staircase alone. That is part of it. But I mean something bigger than that: an assurance that I am, despite imperfections, a real, positive person; that somewhere in the sweeping, intricate pattern of people there is a special place where I can make myself fit.
It took me years to discover and strengthen this assurance. It had to start with the most elementary things. Once a man gave me an indoor baseball. I thought he was mocking me and I was hurt. "I can't use this." I said. "Take it with you," he urged me, "and roll it around." The words stuck in my head. "Roll it around! "By rolling the ball I could hear where it went. This gave me an idea how to achieve a goal I had thought impossible: playing baseball. At Philadelphia's Overbrook School for the Blind I invented a successful variation of baseball. We called it ground ball.
All my life I have set ahead of me a series of goals and then tried to reach them, one at a time. I had to learn my limitations. It was no good to try for something I knew at the start was wildly out of reach because that only invited the bitterness of failure. I would fail sometimes anyway but on the average I made progress.We can learn from the beginning of the passage that __________________.
| A．the author lost his sight because of a car crash. |

A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains: the range of news from local crime to international politics, from sports to business to fashion to science, and the range of comment and special features as well, from editorial page to feature articles and interviews to criticism of books, art, theatre, and music. A newspaper is even more remarkable for the way one reads it: never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality(时事性) , its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient value. For all these reasons, no two people really read the same paper: what each person does is to put together, out of the pages of that day’s paper, his own selection and sequence, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.A modern newspaper is remarkable for all the following except its ________.
| A．popularity | B．uniform style |

| D．different people prefer different newspapers |
It can be concluded from the passage that newspaper readers _________.
| A．apply reading techniques skillfully |
| B．jump from one newspaper to another |
| C．appreciate the variety of a newspaper |
| D．read a newspaper selectively usually |
A good newspaper offers “a variety” to readers because __________.
| A．it has to cover things that happen in a certain locality |

Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate(桂冠). As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi.
Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career.
Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations.
Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them.
Aided by computers, Hoffmann was able to generate a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value.What can be inferred from the above passage about Hoffman?
| A．He left his homeland when he got the Nobel Prize. |
| B．He went to the United States to gain his Nobel Prize. |
| C．He might find the Unites States a better place to learn chemistry. |
| D．His family may have settled in the United States. |
How did Hoffman make his research popular?
| A．He applied some computer skills to help explain his ideas. |
| B．He established a special computer system to help. |
| C．He drew some forms explaining his ideas. |
| D．He did series of experiments to prove his ideas. |
The underlined word “generate” in this passage might most probably mean “______”.
A. bring in B. break down
B. move away D. keep secretWhy was Ronald Hoffman awarded the 1981 Nobel Prize for chemistry?
| A．He established rules to predict chemical reactions . |
| B．He succeeded applying computer science to chemistry research. |
| C．He shared what he had achieved with another scientist named Fukui Kenichi. |
| D．He succeeded in both chemistry and computer researches. |
