Sports are by nature competitive. But recently, the over-competitive nature youth sports seem to have taken on has led to cause for ____.
Those who are strongly against competition point out that in a competition, only one wins while the rest ____. They argue that competition leads children to define themselves by the outcome, tying their self-esteem(自尊心) up with their ability to ____ others. They further argue that competition causes anxiety, affects learning and causes children to view others as____ to their success. Competition restricts participation and ___ success. A “win-at-all-costs” mentality can cause children to pay little attention to honesty and fair play.
On the opposite side of the debate are those who view competition as a ____ part of American society. They argue that placing kids in a competitive situation such as sports helps prepare them for a(n) ____ life in our society that is full of competition. ____ is a normal part of human nature and part of everyday life. Other arguments ____ competitive sports are that they provide challenges, help kids develop skills, and teach them how to get along with others.
The third side of this debate says that a little competition can’t be that ____, as long as competition does not get out of hand and take on a “win-at-all-costs” mentality. They claim that competition in itself is not bad and it can serve as a ____ of social comparison, necessary for adolescents to see how ____ they are. Their advice is to introduce competition ____ while focusing more on mastery and cooperation during childhood. The gradual shift toward competition will allow children to build skills, participate fully, and focus on ____ rather than winning.
It is important that you consider all of the possible ____ of competition before you put your child in a competitive situation.

It’s the place where smart people make smart machines work even smarter. It’s also in the heart of sunny California, a great place to start a family and raise kids. What could be better?
But something is happening to their children. Up until the age of two they develop normally. But then everything seems to go backwards. The children become locked into their own small world, unable to communicate at all.
They call it the “curse(詛咒)of Silicon Valley,” but the medical name for the condi­tion is autism(自閉癥). It used to be thought that autism was a kind of mental illness. Now doctors are sure that it is a neurological disease transmitted genetically. It seems that the people leading the communications revolution are having children who cannot commu­nicate at all.
But even the parents have trouble communicating. Asperger’s Syndrome is a mild version of autism. People who have it are highly intelligent and often brilliant with num­bers or system but have no social skill. This very combination of symptoms makes Asperger’s sufferers into ideal computer professionals.
The Asperger’s sufferer has always been a well—known figure in popular culture. He or she was the eccentric but dedicated scholar or the strange uncle or auntie who never married. But the high numbers of such people in Silicon Valley mean that they can meet others who understand them and share their interests. And while they might not be per­sonally attractive, they can earn truly attractive amounts of money. They can get married and have kids. Unfortunately, many of the children of two Asperger’s parents seem to be developing serious autism.
There is little anyone can do. It takes hours of work just to make autistic child realize that anyone else exists. And there is no cure in sight. Some argue that no cure should be found. “It may be that autistics are essentially different from normal people, but that these differences make them invaluable for the evolution of the human race,” says Dr. Kirk Whilhelmsen of the University of California. “To eliminate the genes for autism could be disastrous. ”
It seems that the children of Silicon Valley are paying the price of genius.
【小題1】What does Dr Kirk Whilhelmsen think of autism?

Pessimistic，anxious and depressed people may have a higher risk of dementia (癡呆)，US researchers reported on Thursday.
A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later.
Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk，the study showed.
“There appears to be a dose­response pattern.That is，the higher the scores，the higher the risk of dementia，”Dr Yonas Geda，a neuropsychiatrist at the Mayo Clinic in Rochester，Minnesota who led the study，said in a statement.
Geda and his colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965.
They all took the Minnesota Multiphasic Personality Inventory，a standard personality and life experience test，Geda’s team told a meeting of the American Academy of Neurology in Miami.
In 2004，the team interviewed the participants or family members.
Those who scored higher for anxiety and pessimism on the test were more likely，as a group，to have developed dementia by 2004，including Alzheimer’s disease and vascular (血管的) dementia.
This did not mean a person who is pessimistic could assume he or she has a higher risk of developing dementia.
“One has to be cautious in interpreting a study like this，”Geda said.
“One cannot make a leap from group level data to the individual.Certainly the last thing you want to do is to say，‘Well，I am a pessimist；thus，I am doomed to develop dementia 20 or 30 years later，’because this may end up becoming a self­fulfilling prophecy (預(yù)言)．”
And there is NOT any specific way to prevent dementia，although many studies have shown that a healthy diet，exercise，keeping active in other ways，doing puzzles and other activities lower the risk.

If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again.       knows this, but nobody would think of     the fact.
Yet there are many people who        to know that the memory works in the same way. When someone says that       has a good memory, he       means that he keeps his memory in practice     exercising it very     , either consciously or unconsciously. When someone else says that his memory is     , he means that he does not give it enough      to become strong. The position is exactly the same as that of       people, one of      exercises his arms and legs by playing ball, while the other       in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own      , But if he tells us that he has a poor memory,      of us think that his parents are to blame, or that he is just     , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind,       all of us can improve our strength and our memory by the same means that      .
Have you ever       that people who cannot read or write usually have      memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.
In a word, if you want to have a good memory, do practice       things。

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were        to show that we all have “a body clock”         us, which controls the        and fall of our body energies,        us different from one day to the next.
The        of “a body clock” should not be too        since the lives of most living things are controlled        the 24 hour night-and-day cycle. We feel        and fall asleep at night and become        and energetic during the day. If the 24 hour-cycle is        , most people experience unpleasant        . For example, people who are not        to working at night can find that        of sleep causes them to        badly at work.
      the daily cycle of sleeping and       , we also have other cycles which       longer than one day. Most of us would        that we feel good on some days and not so good on        ; sometimes our ideas seem to flow and at other times, they        do not exist.
