Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步机). Sometimes they wore running shoes. Other times they ran barefoot (赤脚).
Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of The American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.

Is there a magic cutoff period when children become responsible for their own actions? Is there a wonderful moment when parents can become spectators (audiences) in the lives of their children and shrug, “It’s their life,” and feel nothing?
When I was in my twenties, I stood in a hospital passage waiting for doctors to put a few stitches(缝线) in my son’s head.I asked, “When do you stop worrying?” The nurse said, “When they get out of the accident stage.” My mother just smiled faintly and said nothing.
When I was in my thirties,I sat on a little chair in a classroom and heard how one of my children talked continually and disrupted the class.As if to read my mind, a teacher said.“Don’t worry.They all go through this stage and then you can sit back, relax and enjoy them.” My mother just smiled faintly and said nothing.
When I was in my forties, I spent a lifetime waiting for the phone to ring, the cars to come home, the front door to open.A friend said, “They’re trying to find themselves.Don’t worry; in a few years, you can stop worrying.They’ll be adults.” My mother just smiled faintly and said nothing.
By the time I was 50, I was sick and tired of being weak.I was still worrying over my children, but there was a new wrinkle.There was nothing I could do about it.My mother just smiled faintly andsaid nothing.
I continued to suffer from their failures, and be absorbed in their disappointments.My friends said that when my kids got married I could stop worrying and lead my own life.I wanted to believe that, but I was haunted(萦绕心头) by my mother’s warm smile and her occasional “You look pale.Are you all right? Call me the minute you get home.Are you depressed about something?” Can it be that parents are sentenced to a lifetime of worry?

The cars were honking (鸣叫) on the road one morning as I was walking to the park.I walked on and soon found the cause — a little taxi that had got stuck in the middle of the road.There was sweat on the driver's face as he tried to start the engine again and again — nothing happened."No petrol,"
I said to myself and then found myself getting angry."Why doesn't the fool move his taxi to the side?" I thought, so did all the others who honked and shouted.
He got up tiredly, and the passenger in the taxi got out.He was a young man in a white shirt, who watched the driver try to push it to the side."Stupid guy!" I said."Can't he lend a helping hand? "
I watched as the poor driver pushed it to the side.Cars, buses and trucks went past cursing (咒骂) the poor man.The young man took another taxi and went off.
The taxi driver began mending his taxi."Stupid passenger!" I said to him."He didn't help you!" The taxi driver slowly got up."Sir!" he asked, "Did you?" I looked at him guiltily, then looked away, and walked away fast, asking myself, "Did I help the poor man push his taxi?"
What had I been doing as the traffic jam took place? How had I helped deal with the problem? Did I help the poor man push his taxi? I’d done my bit, with my mouth.But never had I moved to solve the problem.I was shocked with guilt as I heard him asking, "Sir!

American society is not nap (午睡) friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine. “There's even a prohibition (禁止) against admitting we need sleep”. Nobody wants to be caught napping or found asleep at work. To quote a proverb: Some sleep five hours, nature requires seven, laziness nine and wickedness eleven? Wrong. The way not to fall asleep at work is to take naps when you need them.
“We have to totally change our attitude toward napping”, says Dr. William Dement of Stanford University, the godfather of sleep research.
Last year a national commission led by Dement identified an “American sleep debt” which one member said was as important as the national debt; the commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, President Clinton is trying to take a half hour snooze (打瞌睡) every afternoon.
About 60 percent of American adults nap when given the opportunity. We seem to have “a mid-afternoon quiet phase” also called “a secondary sleep gate.” Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap. We Superstars of Snooze don't nap to replace lost shut eye or to prepare for a night shift. Rather, we “snack” on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums. It is commonly accepted in American society that too much sleep is _______.
| A.unreasonable | B.criminal | C.harmful | D.costly |
The research done by the Dement commission shows that Americans _______.
| A.don't like to take naps | B.are terribly worried about their national debt |

The purpose of this article is to _______.
| A.warn us of the wickedness of napping | B.explain the danger of sleepiness |
| C.discuss the side effects of napping | D.convince the reader of the necessity of napping |
The “American sleep debt” (Line 1, Para. 3) is the result of _______.
| A.the traditional misunderstanding the Americans have about sleep |
| B.the new sleep policy of the Clinton Administration |
| C.the rapid development of American industry |
| D.the Americans’ worry about the danger of sleepiness |
For several days I saw little of Mr. Rochester. In the morning he seemed much occupied with business, and in the afternoon gentlemen from the neighborhood called and sometimes stayed to dine with him. When his foot was well enough, he rode out a great deal.
During this time, all my knowledge of him was limited to occasional meetings about the house, when he would sometimes pass me coldly, and sometimes bow and smile. His changes of manner did not offend me, because I saw that I had nothing to do with the cause of them.
One evening, several days later, I was invited to talk to Mr. Rochester after dinner. As I was looking at him, he suddenly turned, and asked me, “Do you think I’m handsome, Miss Eyre?”
The answer somehow slipped from my tongue before I realized it: “No, sir.”
“Ah, you really are unusual! You are a quiet, serious little person, but you can be almost rude.”
“Sir, I’m sorry. I should have said that beauty doesn’t matter, or something like that.”
“No, you shouldn’t! I see, you criticize my appearance, and then you stab me in the back! You have honesty and feeling. There are not many girls like you. But perhaps I go too fast. Perhaps you have awful faults to counterbalance your few good points.”
I thought to myself that he might have too. He seemed to read my mind, and said quickly, “Yes, you’re right. I have plenty of faults. I went the wrong way when I was twenty-one, and have never found the right path again. I might have been very different. I might have been as good as you, and perhaps wiser. I am not a bad man, take my word for it, but I have done wrong. It wasn’t my character, but circumstances which were to blame. Why do I tell you all this? Because you’re the sort of person people tell their problems and secrets to, because you’re sympathetic and give them hope.”
“Don’t be afraid of me, Miss Eyre.” He continued. “You don’t relax or laugh very much, perhaps because of the effect Logwood school has had on you. But in time you will be more natural with me, and laugh, and speak freely. You’re like a bird in cage. When you get out of the cage, you’ll fly very high. Good night.”At the beginning Miss Eyre’s impressions of Mr. Rochester were all except _______.
| A.friendly | B.sociable | C.busy | D.changeable |
Why did Mr. Rochester say “…and then you stab me in the back!” (the seventh paragraph)?
| A.Because Jane had intended to kill him with a knife. |

| A.tell her all his troubles | B.tell her his life experience |
| C.change her opinion of him | D.change his circumstances |
At the end of the passage, Mr. Rochester sounded _______.

Violin prodigies(神童), I learned, have come in distinct waves from distinct regions. Most of the great performers of the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe. I asked Isaac Stern, one of the world’s greatest violinists, the reason for this phenomenon. “It’s very clear, “he told me. “They were all Jews and Jews at the time were severely oppressed and ill-treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage.” As a result, every Jewish parent’s dream was to have a child in the music school because it was a passport to the West.
Another element in the emergence of prodigies, I found, is a society that values excellence in a certain field and is able to nurture (培育) talent. Nowadays the most nurturing societies seem to be in the Far East. “In Japan, a most competitive society with stronger discipline than ours,” says Isaac Stern, “children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War II, that music not only became part of their daily lives, but it became a discipline as well.” The Koreans and Chinese, as we know, are just as highly motivated as the Japanese.
That’s a good thing, because even prodigies must work hard. Next to hard work, biological inheritance plays an important role in the making of a prodigy. J. S. Bach, for example, was the top of several generations of musicians, and four of his sons had significant careers in music.Jewish parents in Eastern Europe longed for their children to attend music school because ______.
| A.it would allow them access to a better life in the West |
| B.Jewish children are born with excellent musical talent |
| C.they wanted their children to enter into the professional fields |
| D.it would enable the family to get better treatment in their own country |
Nurturing societies as mentioned in the passage refer to societies that ______.
| A.enforce strong discipline on students who want to achieve excellence |
| B.treasure talent and provide opportunities for its full development |
| C.encourage people to compete with each other |
| D.promise talented children high positions |
Japan is described in the passage as a country that attaches importance to ______.
| A.all-rounded development | B.the learning of Western music |
| C.strict training of children | D.variety in academic studies |
Which of the following contributes to the emergence of musical prodigies according to the passage?
| A.A natural gift. | B.Extensive knowledge of music. |
| C.Very early training. | D.A prejudice-free society. |
