Attention deficit(不足)hyperactivity(活动过度)disorder is known by the letters A.D.H D.Children with A.D.H.D.might have trouble paying attention.They might not seem to listen and might forget things.They might not be able to stay seated or play quietly.They might talk too much and act and speak without thinking about the results of their behavior.These are among the signs named on the web site of America’s Centers for Disease Control and Prevention.
Doctors usually identify the disorder in children.But experts say the behaviors often last into adulthood.Researchers have been looking for the cause or causes of attention deficit hyperactivity disorder.Now, a brain-imaging study offers more evidence that could lead to new ways to treat it.Researchers say they observed shortages in the brain's reward system in patients with A.D.H.D.The study found that levels of some proteins were lower than normal.Nora Volkow, director of the National Institute on Drug Abuse, says the lack of attention and self –control that mark A.B.H.D. could be caused by problem in the flow of dopamine(多巴胺). She says people might have difficulty completing an activity if they cannot expect some kind of reward in return. Researchers studied the pathways on which dopamine travels and A.D.H.D. Doctor Volkow says the researchers then compared the pathways to those of 44 adults without the disorder. “There was a lower concentration of dopamine markers in the brain of individuals with A.D.H.D., specifically in the areas of the brain that are involved with reward and motivation. And the dopamine levels were directly linked to the severity, of the patient’s inattention she says.”
The study used brain images taken at Brookhaven National Laboratory in new York State. Gene-Jack Wang is chairman of the Brookdhaven medical department. He says the finding might also help explain why people with A.D.H.D.
are more likely to abuse drugs or overeat. He says they might be attempting to increase their dopamine levels to make up for the deficits in their reward system.

Lisa is ten years old. She is handicapped(残疾的)because she has brain damage. She could not do even the simplest thing until a year ago. She could not comb(梳理)her hair or feed herself. Her parents loved her. But they treated her like a baby.
Mr. Ching has a daughter and a son. They are both grown. They live far from their father. Mr. Ching felt lonely. He decided to do something about it. He decided to become a foster grandfather to a handicapped child. And that was how he met Lisa.
Foster grandparents are grandparents who are not related by birth, but foster grandparents love the children they care for. They love them just as natural grandparents love their grandchildren.
The foster grandparents also help the handicapped children in special ways. They help to dress and feed the children. They read to them and tell them stories. They also help with handicapped children’s therapy. Therapy is the treatment of a disease or disorder. It helps the children overcome their handicaps.
Mr. Ching became a foster grandparent to Lisa when she was nine years old. At first, Lisa was shy. She was afraid because Mr. Ching was a stranger. But he came to see her every day. Gradually, she began to trust him.
At last Lisa let Mr. Ching do things for her. He came at lunchtime and fed her. One day he handed the spoon (匙子)and guided it to her mouth. He told her she must learn to feed herself.
“Most of that lunch ended up on us instead of in Lisa’s mouth,”Mr. Ching remembers.“But it was a start for Lisa. She learned to feed herself in a few months.”
Then Lisa was ready for more therapy, thanks to Mr. Ching. She had learned to do one simple thing. She could learn to do other simple things. Mr. Ching was trained to help with Lisa’s therapy.
To become foster grandparents, people must be at least sixty years old and in good health. They must be willing to give their time to handicapped children. They are volunteers (志愿者),so they are not paid. They are given money for expenses such as transportation.
Mr. Ching speaks for most foster grandparents when he says,“We all benefit (受益). The handicapped children benefit because we help them live more useful live. And we benefit because we know the children need us and love us. For any person, There’s no greater happiness than that!”

We don't plan to cry, but it just happens. In fact when we feel sad or angry, a good cry is almost impossible to resist. But if you didn't know what crying was, you'd have to wonder why some strong feelings started water streaming from people's eyes and why they seemed to feel better afterwards.
Now a US researcher has found there may be more in crying than we think. William H. Frey II, author of “Crying:The Mystery of Tears”, believes it may really be one of the body's clever self-repair mechanisms(机制). Crying may be a way of getting rid of the byproducts(副产品) of stress(压力), he says.
He has found that tears contain some chemicals which can cause stress. One of these is the hormone prolactin(激素) which is set free when one is feeling stressed. Since women have more of this than men, that might explain why they usually cry more, he suggests.
Unsurprisingly, Dr. Frey's study seemed to prove that most people feel better after a good cry. And sex has nothing to do with it-the result was true for women and men. So, next time when you feel like bursting into tears, go ahead. If Dr. Frey is right, you'll be doing yourself a favor.

[ ]
A.their bodies contain less hormone prolactin
B.their tears contain more chemicals
C.they are not so full of feelings as women
D.the chemicals in their tears can't cause stress
4.The author advised us ________.
[ ]
A.to plan to cry very often
B.not to cry any more
C.to go outdoors without hesitation
D.to cry as we want to
5.Which of the following is not true according to the passage?
