What happens inside the skull of a soccer player who repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at a Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”, like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.The passage is most probably a______.
| A．news report |
| B．research report |
| C．story for soccer players |
| D．text for doctors |
In which way can we find the structural changes in the brain?
| A．Computerized test. | B．Questionnaire.. |
| C．Scanning. | D．M.R.I. technique. |
From the passage we can conclude that frequent heading may have_____.
| A．significant effect on brain |
| B．little effect on one’s brain |
| C．nothing to do with the brain injury |
| D．one’s memory improved |
The underlined word "fumbling" is closest in meaning to______.
| A．remembering | B．misunderstanding |
| C．recalling | D．missing |
In recent years many countries of the world have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more various jobs lead to greater productivity? There are facts to suggest that while variety certainly makes the worker's life more enjoyable, it does not actually make him work harder. As far as increasing productivity is concerned, then variety is not an important factor.
Other experts feel that giving the worker freedom to do his job in his own way is important, and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery that must be used in a fixed way. Thus while freedom of choice may be important, there is usually very little that can be done to create it.
Another very important consideration is how each worker contributes to the product he is making. In most factories the worker sees only one part of the product. Some car factories are now experimenting with having many small production lines rather than one large one, so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of the worker’s contribution an important factor, therefore, but it is also one we can do something about.
To what degree does more money lead to greater productivity? The workers themselves certainly think this is important. Maybe they want more money only because the work they do is boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.Which of the following is the best way to make workers work harder according to the author?
| A．Increasing their pay. |
| B．Giving them more spare time. |
| C．Making the work itself meaningful. |
| D．Replacing large production lines with small ones. |
The reason why a worker cannot have freedom in doing the job in his own way is that ___ .
| A．the machine is so badly needed that more of it should be bought |
| B．there are e production lines in factories |
| C．the bosses can create very little freedom of choices |
| D．the machines must be operated strictly according to instructions and rules |
Besides money, what may make workers work more actively?
| A．extra free hours | B．More comfort of life |
| C．interesting jobs | D．better working conditions |
The best title for this passage may be _______.
| A．Problems of Modern Workers | B．Making Jobs More Interesting |
| C．Pushing Workers to Produce More | D．How to Improve Labor Productivity |
Maggie was very glad that James was not a frequent visitor to the house. So far as the children were concerned, they had a mystery about him that stirred their imagination. He stirred Maggie’s anger, however, so that she often said to her husband, “It’s mercy that brother of yours doesn’t come oftener.”
In fact James came once a year, unexpectedly, around eight o’clock in the evening, and he stayed for six hours of close discussion with his brother. His arrival was a signal to the children that their bedtime would be delayed. Not that he ever spoke to them or played with them. He took no notice of them, as if he was unable to see children, at least until the time came for him to go. Instead, after his first greeting and a careless kiss, James took no notice of Maggie either, except to add, “You’ll be getting on with the supper, Maggie.” Such was his regard for her.
Maggie paid him back in her own way. She kept the children up, the four of them, to keep her company, she said, but of course they sang and made a noise and broke the endless sound of James’s voice. Very late, they dropped off to sleep in their chairs. Then, when James was about to go, Maggie woke them up and so more or less forced him to part with four shillings before he left. That gave her some satisfaction, for James, though rich, was mean. He always went home by the last train, just after two o’clock.
Maggie’s children secretly stared at their uncle. They could not forget that he had, in their mother’s words, “lost two wives and taken a third, ” They wondered about those two unfortunate lost ladies. They asked each other what their fate had been, and if neither could ever be found again. James never brought his third wife with him nor ever mentioned her. The children decided that he must be so frightened of losing her that he never allowed her outside the door. The underlined word “mercy” in the text most probably means _______.
| A．loss | B．wonder |
| C．lucky thing | D．terrible thing |
Maggie never prepared anything special for James because _______.
| A．he was a man difficult to please |
| B．she never knew when he was coming |

What do we know about James’ behavior?
| A．He was a kind man, with love for the family. |
| B．He was generous, especially towards his brother. |
| C．He was anxious to please the family, especially the kids. |
| D．He was rude to his sister-in-law. |

Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “Mom, I can’t peel potatoes. I have only one hand.”
Mom never looked up from sewing. “You get yourself into that kitchen and peel those potatoes,” she told me. “And don’t ever use that as an excuse for anything again!”
In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.
That night I told Mom about it. She hugged me, and I saw her “we’ll see about that” look. The next afternoon, she took me back to school. At the deserted playground, Mom looked carefully at the bars.
“Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other elbow. Day after day we practiced, and she praised me for every rung I reached. I’ll never forget the next time, crossing the rungs, I looked down at the kids who were standing with their mouths open.
One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mom come into my room. “Mom,” I said, weeping, “none of the boys would dance with me.”
For a long time, I didn’t hear anything. Then she said, “Oh, honey, someday you’ll be beating those boys off with a bat.” Her voice was faint and cracking. I peeked out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.。Which of the following expressions can be used most suitably to describe Mom’s attitude when she made the child to peel potatoes?
| A．Cruel. | B．Serious. | C．Strict. | D．Cold. |

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?As pointed out at the beginning of the passage, people used to think that air pollution _______.
| A．cause widespread damage in the countryside |
| B．affected the entire eastern half of the United States |
| C．had damaged effect on health |
| D．existed merely in urban and industries areas |
As to the greenhouse effect, the author __________.
| A．share the same view with the scientist. |
| B．is uncertain of its occurrence |
| C．rejects it as being ungrounded |
| D．thinks that it will destroy the world soon |
The word “offset” in the second paragraph could be replaced by _________.
| A．slip into | B．make up for | C．set up | D．catch up with |
It can be concluded that ____________.
| A．raising the world’s temperature only a few degrees would not do much harm to life on earth |
| B．lowering the world’s temperature merely a few degrees would lead major farming areas to disaster |
| C．almost no temperature variations have occurred over the past decade |
| D．the world’s temperature will remain constant in the years to come |
This passage is primarily about __________.
| A．the greenhouse effect | B．the burning of fossil fuels |
| C．the potential effect of air pollution | D．the likelihood of a new ice age |
You must have been troubled by when to say "I love you" because it is one of the greatest puzzles in our life.
What if you say it first and your partner doesn’t love you back? Or if they do say it but you don’t feel they mean it? Being the first to declare your love can be never racking (紧张) and risky and can leave you feeling as vulnerable as a turtle with no shell. But is the person who says it first really in a position of weakness? Doesn’t it pay to hold back, play it cool and wait until the other half has shown their hand faster?
“A really good relationship should be about being fair and being equal,” says psychologist Sidney Crown. “But love is seldom equal.” “All relationships go through power struggles but,” he says, “if a love imbalance continues for years, the rot will set in.” That feeling of “I’ve always loved you more” may be subverted (颠覆，破坏) for a time, but it never goes away completely and it often emerges in squabbling (大声争吵). In love, at least, the silent, withholding type is not always the most powerful. “The strongest one in a relationship is often the person who feels confident enough to talk about their feelings,” says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. "The one with the upper hand is often the person who takes the initiative.” In fact, the person who says “I love you” first may also be the one who says “I’m bored with you’ first.” Hall believes that much depends on how "I love you" is said and the motivation of the person saying it. Is it said when they’re drunk? Is it said before their partner flies off on holiday, and what it really means is “Please don’ t be unfaithful to me” ? By saying “I love you”, they are really saying “Do you love me?” If so, wouldn’t it just be more honest to say that. Collins agrees that intention is everything. "It’s not what is said, but how it’s said. What it comes down to is the sincerity of the speaker.”What is the main idea of this passage?
| A．The importance of "I love you" | B．The meaning of "I love you" |
| C．The time of saying "I love you". | D．The place of saying "I love you" |
In the first sentence the author means that____________.
| A．it is easy to say "I love you" |
| B．it is hard to say "I love you" |
| C．we have many troubles in our life |
| D．people usually do not know when to say "I love you" |
According to the expert, a good relationship should be _____________.
| A．fair and equal | B．fair and kind |
| C．powerful and equal | D．confident and fair |
In the third paragraph, the phrase "with the upper hand" means __________.
| A．being low in spirit | B．having only one hand |
| C．being active | D．being passive |
What is the most important for you to consider when somebody say "I love you" to you?
| A．The intention. | B．The place. | C．The time. | D．The determination. |
