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.

One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states.” said Neville Alexander, Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town.
In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 “Toubon law” in France, but the idea has been copied in many countries since then. Such efforts to govern language use are often dismissed as futile by language experts, who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.
It is especially difficult for native speakers of English to understand the desire to maintain the “purity” of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world, but there has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.
The need to protect national languages is, for most western Europeans, a recent phenomenon—especially the need to ensure that English does not unnecessarily take over too many fields. Public communication, education and new modes of communication promoted by technology, may be key fields to defend.Neville Alexander believes that.
| A．mother-tongue education is not practiced in all African countries |
| B．lack of mother-tongue education can lead to economic failure |
| C．globalization has led to the rise of multi-language trends |
| D．globalization has resulted in the economic failure of Africa |
The underlined word “futile” (in paragraph 2) most probably means ““.
| A．useless | B．practical | C．workable | D．unnecessary |
Why do many English-speaking countries not support the language protection efforts described in the passage?
| A．They think language protection laws are ineffective. |
| B．They want their language to spread to other countries. |
| C．They have a long history of taking words from other languages. |
| D．It reduces a language’s ability to acquire international importance. |
What can we infer from the last paragraph?
| A．English has taken over fields like public communication and education. |
| B．Europeans have long realized the need to protect their national languages. |
| C．Most language experts believe it is important to promote a national language. |
| D．Many aspects of national culture are threatened by the spread of English. |

So long as teachers fail to distinguish between teaching and learning, they will continue to undertake everything to do for children that only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also a public activity. It can be seen and observed.
Learning to read, however, involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest (探索) for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.The problem with the reading course as mentioned in the first paragraph is that
________.
| A．it is one of the most difficult school courses |
| B．students spend endless hours in reading |
| C．reading tasks are assigned with little guidance |
| D．too much time is spent in teaching about reading |

| A．teachers can improve conditions at school for the students |
| B．teachers can enable students to develop their own way of reading |
| C．teachers can devise the most efficient system for reading |
| D．teachers can make their teaching activities observable |
The underlined word “scrutiny” most probably means “________”.
| A．inquiry | B．observation | C．control | D．suspect |
According to the passage, learning to read will no longer be a difficult task when
________.
| A．children become highly motivated |
| B．teacher and learner roles are interchangeable |

| D．reading enriches children’s experience |
The main idea of the passage is that ________.
| A．teachers should do nothing in helping students learn to read |

He is a lesson to every boy who ever picked up a basketball and dreamed that it would change his life.
The lights were never brighter and the crowds were never bigger for a homegrown sports hero than they were a quarter-century ago for Ray Hall. But his athletic achievements, as impressive as they are, are to my mind not what is most admirable about the man.
Known as “Sugar Ray” in his teens, Hall was rated among the country’s top 25 high school basketball players. An inner-city kid from a solid family, Hall took on the challenge of lifting Canisius College — still recovering from its failure — back to respectability, rejecting more favorable offers. His status of a savior (救世主) brought more pressure than any 18-year-old should have to handle. However, I watched him mature into the player who led Canisius back to daylight.
After college Hall played professionally in Italy and Greece for over 10 years until a car accident at 32 ended his basketball career. The news that he would never play again shocked Hall but unlike so many others he was ready for life after basketball. When I met Hall — still fit at 46 — for lunch Monday, he wore a cut-sharp gray suit, designer tie and blazing white shirt that screamed Success. “That was always the question — when the cheers end, where do you go? Who do you turn to?” he said. “It starts and ends with that person in the mirror.”
Hall got the concept of academics-first from his parents. He graduated from Canisius a semester early. “No matter how good of an athlete you are, you are just one injury away from losing it all,” he said. “But if you take care of things academically, you are prepared until you leave this earth.”
For the past 14 years, he has been in a computer sales job at Ingram Micro. He married his college sweetheart. They have three kids and a nice house in the suburbs. He figured out early what others learn too late: Athletics is part of a journey, not the destination.
Congratulations, Ray, you made it. In more ways than one.Ray was regarded as a savior because ________.

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely.
In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the dilemma. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is — politics, the laws of physics, or the proper way to break an egg — the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority — someone who actually knows something — and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.Why does the author compare the parent-teen war to a border conflict?
| A．Both can continue for generations. |
| B．Both are about where to draw the line. |
| C．Neither has any clear winner. |
| D．Neither can be put to an end. |
What does the underlined part in Paragraph 2 mean?
| A．The teens blame their parents for starting the conflict. |
| B．The teens agree with their parents on the cause of the conflict. |
| C．The teens accuse their parents of misleading them. |
| D．The teens tend to have a full understanding of their parents. |
Parents and teens want to be right because they want to ________.
| A．give orders to the other | B．know more than the other |
| C．gain respect from the other | D．get the other to behave properly |
What will the author most probably discuss in the paragraph that follows?
| A．Causes for the parent-teen conflicts. |
| B．Examples of the parent-teen war. |
| C．Solutions for the parent-teen problems. |
| D．Future of the parent-teen relationship. |
