The mental aspect of athletics is underrated. The common expression, “athletics are 90 percent ____ and 10 percent physical,” is often used by coaches, and stresses that mindsets make a huge ____ in competitions.
“The physical aspect of the sport can only take you ____ ,” said Olympic gold medal-winning gymnast Shannon Miller during an interview with the Dana Foundation. “The mental aspect has to ____ , especially when you’re talking about the best of the best. In the Olympic games, everyone is talented. Everyone ____ hard. Everyone does the work. What ____ the gold medalists from the silver medalists is simply the mental game.”
Many athletes have used the technique of mental imagery, or ____ , to perform at their best. Research on the brain patterns of ____ found that the patterns activated when a weightlifter lifted heavy weights were activated ____ when they simply imagined lifting and some studies have suggested that mental ____ can be almost as effective as physical training. One study, published in the Journal of Sport & Exercise Psychology in 1996, found that ____ weight lifting caused ____ changes in muscle activity.
“Mental imagery ____ many cognitive (认知的) processes in the brain: motor control, attention, perception, planning, and memory,” researcher Angie LeVan wrote in Psychology Today. “So the ____ is getting trained for actual performance during visualization. It’s been found that mental practices can enhance motivation, increase confidence, improve motor performance and ____ your brain for success.”
____ visualizing is more than just thinking about an upcoming event. ____ athletes use visualization, they truly feel the event taking place in their mind’s eye.
“During visualization, she incorporates (整合) all of her ____ into the experience,” sports psychologist Dr JoAnn Dahlkoetter wrote in a blog post on The Huffington Post ____ a speed skater she works with. “She feels her forefoot pushing off the track, she hears her skating splits, and she sees herself racing ahead of the competitors. She experiences all of the elements of her race ____ before executing (完成) her performance.”

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(诅咒)of Silicon Valley,” but the medical name for the condition is autism(自闭症). 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.What does Dr Kirk Whilhelmsen think of autism?
| A．It is disastrous to society. |
| B．It is not completely a bad thing. |
| C．It is a punishment to those working in Silicon Valley. |
| D．People with autism should never marry. |
What can we learn about autism according to the passage?
| A．It is believed to be a king of mental illness that can be cured. |
| B．People with autism can’t find people sharing their interests. |
| C．They do not care about the presence of others. |
| D．They are a burden for the society. |
Why do people call autism “curse of Silicon Valley”？
| A．Because autistic people live in Silicon Valley. |
| B．Because many people working in Silicon Valley have autism children. |
| C．Because people with autism will be driven out of Silicon Valley. |
| D．Because people with autism are not personally attractive and not liked by others. |
What can we know about Asperger’s Syndrome according to the passage?
| A．Asperger’s sufferers are ideal computer professionals. |
| B．Asperger’s sufferers never get married and have children. |
| C．Asperger’s sufferers are ashamed of themselves and locked into their own world. |
| D．Asperger’s sufferers can be beneficial to society if they are cured. |

A noted American psychologist once remarked that childhood is a magical period in one’s life．Indeed it is, for during one undergoes a step-by-step transformation not only in mental capacity, but also in physical and verbal skills．Each step an increase in the difficulty of a child’s conceptual and learning abilities．During the early stages of childhood, from infancy to about five, the child learns skills including using the toilet, bathing and dressing himself independently．At this stage, he also learns to be very observant, curious, imaginative and creative．His ability to remember things also at this stage． He remembers details that an adult may have difficulty in remembering．Gradually , he learns elementary skills in problem-solving．At school, particular in classes, the child is especially creative．Given a piece of paper and some colored pencils, he draws a variety of from his surroundings as well as from his circle．It is not surprising to see a child draw a monster to represent an abusive father, and an angel to represent a loving and caring mother．
As he graduates to the later stages of childhood bordering on the teenage years, the child learns the of human relations and socialization by interacting with his peers—his friends and schoolmates． He also learns to with new life situations, including dates and part-time work． Given a tight schedule of schoolwork, the child learns to prepare his own schedules of work and play; the more________ and less serious ones manage to take time out of their busy schedules of assignments, reports and tests and examinations to go with their friends on relaxation entertainment．

Pessimistic，anxious and depressed people may have a higher risk of dementia (痴呆)，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 (预言)．”
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.What is the passage mainly about?
| A．It is impossible for people to avoid dementia. |
| B．People who always have negative feelings may have a higher risk of getting dementia. |
| C．If we have a healthy diet，we would have no chance of getting dementia. |
| D．A person who is pessimistic has a higher risk of developing dementia. |
According to the passage，which of the following is TRUE?
| A．There are many ways to prevent dementia effectively. |
| B．A person who is pessimistic is sure to get dementia. |
| C．Those who lead a happy life will not get dementia when they are old. |
| D．Those who scored high for pessimism might have a higher risk of dementia. |
Which of the following does NOT help reduce the risk of getting dementia according to the passage?
| A．A healthy diet. | B．Proper exercises. |
| C．Doing puzzles. | D．Getting up early. |
Which of the following words is not close to the meaning of the word “pessimistic”？
| A．Cheerless. | B．Optimistic. |
| C．Unhappy. | D．Upset. |

Beware of those who use the truth to deceive(欺骗). When someone tells you something that is , but leaves out important information that should be , he can create a false impression.
For example, someone might say, “I just a hundred dollars on the lottery. It was great. I took that dollar ticket back to the store and it in for one hundred dollars!”
This guy is a winner, ? Maybe, maybe not. We then discover that he bought two hundred , and only one was a winner. He’s really a big !
He didn’t say anything that was , but he deliberately left out some important . That’s called a half-truth. Half-truths are not technically , but they are just as not .
Untrustworthy candidates in campaigns often use this tactic(手段). Let’s say that during Governor Smith’s last term, the state lost one million jobs and three million jobs. Then she another term. One of her opponents runs an ad , “During Governor Smith’s term, the state lost one million jobs!”That’s true. , an honest statement would have been, “During Governor Smith’s term, the state had a net gain of million jobs. ”
Advertisers will sometimes use half-truths. It’s the law to make false claims so they try to mislead you with the . An ad might boast, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples. ”It to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.

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.

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.
