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 (腦震蕩) 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 (外傷的) 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.

What do those countries in the world have in common? People are killing each other or driving others out of their families. Why is this hap pening? Very simple, really: in each h of these places, and elsewhere in the world, one group of people believes that another group is different from them and dangerous to them. It has been thus throughout history. How different are humans from each other?
We come in different colors: red, blank, white, yellow and brown; we have a variety of political systems, social systems, religious views(宗教信仰) or none at all; we are different in mind, have different educational systems, different socio-economic classes. We speak different languages, and have different customs and dresses.
If we were to break each of these further, we would have quite a long list of qualities and characteristics that make humans appear to be different from each other. I say they appear to be different , because most of what I have listed stands for what we see or hear, not what is true of human. Man is man everywhere, which is only because where he lives. when he lives there, with whom he lives there, and all have effect on how he lives, that is, what he believes, what he wears, his customs, his gods, his language and so on. These are man-made fact that each group develops over time living together, facing the same problems, needing and desiring the same things. They are his culture. The truth is that we are much more the same than different. If you wear one type of clothing and I wear another, we both wear some kind of clothing. Our culture demands it. If you speak one language and I another, we both speak so that others will understand us. We must communicate with each other. Nothing is gained by giving too many differences, but much lost . If we understood our differences as the ones of culture, then we could make our world more peaceful.
Difference doesn't mean better or worse, right or wrong . It means only that differences have been made by society. Differences produce variety of thought, feeling and action, and that can be very helpful to work out human problems peacefully.
1.We've learned from the passage that ________.
[ ]
A.people are different

2.People in those countries fight each other for ________.
[ ]
A.they have different colors
B.they have different customs and dresses
C.they have different education systems
D.some people think that other people arc different and harmful to them
3.If we pay much attention to differences ________.
[ ]

B.we'll produce problems
C.we'll develop
D.nothing will be lost

閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項。
If you have to miss one meal day(or if you want to do so),which meal will cause you fewest health problems if you don't eat it? lf they have to make a decision of this type,most people(especially dieters or very busy people)will choose to skip breakfast.
However,many experts in the field of health consider breakfast(the meal which “breaks”your“fast”which started the night before)to be the most important meal of the day.If we eat a good breakfast,they say,we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humor.Nevertheless,many people skip breakfast or substitute a donut and a cup of coffee for a well-balanced meal.What hap-pens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people.Participants included both males and females who ranged in age from 12 to 83.During the experiment,these people were given a variety of breakfasts,and sometimes,they had to skip breakfast completely.Special tests,including blood tests and endurance tests,were set up to analyze how well the participants'bodies functioned when they had eaten a certain kind of breakfast.
The results showed that if a person eats an adequate breakfast,he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast.This fact appears to be especially true if a person's work involves mental activity.The study showed that if schoolchildren eat fruit,eggs,bread,and milk before going to school,they will learn more quickly and will be able to concentrate on their lesson for a longer period of time than if their breakfast diet is inadequate.
The study also showed that,contrary to what many people believe,if you skip break-fast,you will not lose weight.This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing.So remember,if you are on a diet,skipping breakfast will not help you.You will probably lose more weight if you reduce your other meals.
1.According to the passage,if people must miss one meal a day,most of them would skip________.
[ ]
2.In many experts'eyes in the field of health,which of the following is the most important meal of the day?
[ ]
3.From the recent study,we can find________.
[ ]
A.if a person skips breakfast or eats a very poor breakfast,he or she will work more efficiently and more productively
B.if a person eats an adequate breakfast,he or she will gain weight
C.if a person's work involves mental activity eats a rich breakfast,he or she will work efficiently
D.if a child doesn't eat breakfast,he will learn more quickly
4.Which of the following is true?
[ ]
A.If you skip breakfast,you will work with energy
B.If you skip breakfast,you will lose weight
C.Breakfast is the most important meal of the day
D.If you are off on a diet,you can skip breakfast
