What happens inside the skull of a soccer player when 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 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.

A week ago, I had the great pleasure of reading an e-book, When Money Talks, Listen! By Rich Ezzo. It took only about an hour to read.
When I first received a copy, I thought it was a Get Rich Quick type of publication. Nothing is wrong with Get Rich Quick, but my mind just doesn’t chase after dreams of wealth. I think that if God ever wants me to be rich, he knows where to find my purse.
When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn’t money hungry either. He, too, is hungry far more important than money.
Since I love this e-book so much, why wait a week to write the review? Simple. I wanted to see if the effect it had on me was a keeper. After reading the last word of the e-book, I totally agreed with the subtitle which promised to forever change the way we thought about money. I had so many thoughts running around my mind that I had to install(安装) a stoplight to stop some while others made their way into the picture, then I yielded(让路) them as a few ones arrived in town. I had a mental traffic jam, which only goes to show how slow the traffic usually is.
It has been a week and the effect is the same. I truly do look at money differently and have even done a few things differently this week. This is an e-book you’ll want to read, I promise. I often recommend books to my daughter, and this is one that I didn’t just “suggest”---I left it open at the bottom of the computer and told each one, “Read it, you’ll love it.”
I would never point someone in a direction I wouldn’t go myself. I urge you to visit the author’s website, Myster Money, and to download the e-book. You won’t regret it.

查看习题详情和答案>>What do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportunity to make money.
Eight students from No 2 Secondary School Attached to East China Normal University started a virtual(虚拟的)company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction(拍卖)a week ago. The company, which has recruited around 20 student staff members, has earned over 2000 yuan in the past three months.
“We donated part of the money to a poor school in the countryside of Anhui Province. It's great to realize our ideal of ‘spreading love and culture with seeds’ after many tests and lots of hard work,” said Senior 2 Shi Chen, CEO of the company.
Just like any other company, Shi's didn't develop smoothly. Shi and her young colleagues(同事)used to sell fresh flowers and old books, and later found seeds might be something that their company could engage in. They bought seeds of various plants and flowers at low prices from a local farm and sold them in schools or on streets. The creative students also made accessories and pictures with different seeds.
With little business knowledge, the students had to learn new skills as the leaders of different departments, such as public relations (PR), sales and marketing. They persuaded a joint Sino-French company near their school to give them training in business management.
“They helped us overcome our shyness. We also learned quite a lot of business theory. I found communication skills and teamwork are very important for my job” said Senior 1 Qian Yifei.
The 16-year-old was elected as PR manager thanks to her talent for speaking. She is also in charge of after sales service, dealing with complaints and providing suggestions.
As the head of the company, CEO Shi has a lot more to think about. First of all, she has to learn how to make her colleagues work efficiently(高效地) as the company only opens at weekends due to all their studies.
“It makes the company more formal,” she said.
The purpose of opening the company is to .
A.earn money for their education fees.
B.spread love and culture with seeds.
C.see whether they can open a company.
D.collect money to open a Hope School.
According to Qian Yifei, what matters most in dealing with public relations?
A.Communication skills and teamwork 。
B.Creative and critical thinking.
C.Educational back ground.
D.Business theories.
What does the word "it" (in the last paragraph) refer to?
A.Selling seeds.
B.CEO.
C.Every colleague's knowledge.
D.To make her colleagues work efficiently.
We can learn from the passage that____.
A.the company is owned by 20 students.
B.the company is over-night successful.
C.the company sells fresh flowers and old books
D.the company gets much help from other company selling seeds.
查看习题详情和答案>>A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.
The unpunctual man, on one hand, never does what he has to do at the proper time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be regained. Time is more valuable than material things. In fact, time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset (财产) as well as other’s. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time and seldom complains of want of it. He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.
Failure to be punctual in keeping one’s appointments is the sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.
Unpunctuality, moreover, is very harmful when it comes to do one’s duty, whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men.
What does the author think is the main difference between a punctual person and an unpunctual person?
A. A punctual person does everything ahead of time while an unpunctual person does everything behind schedule.
B. A punctual person does everything at the right time while an unpunctual person seldom does anything at the correct time.
C. A punctual person has a lot of appointments while an unpunctual person has few appointments.
D. A punctual person has much time to do everything while an unpunctual person has little time to do anything.
According to the passage, the main reason that a person is always unpunctual is that _______.
A. he has more work to do than other people
B. he is always in a hurry when he works
C. he doesn’t care much about time
D. he always mismanages and wastes his time
According to the third paragraph, when you are invited to dinner, you should arrive there _______.
A. after other guests have arrived
B. before all other guests
C. at the appointed time
D. after the host has got things ready
Which of the following statements best describes the harm of unpunctuality?
A. If you are an unpunctual person, you cannot be in charge of any important task.
B. If your friends know that you are unpunctual, they may not see you again.
C. Unpunctuality may bring about heavy losses for both public and private affairs.
