　 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.

My daily routine included going to the gym for a workout before going to work. Every morning I would see my friend Nicholas at the gym. He was seventy - nine years old and in terrific shape. As I greeted Nicholas on this particular day, he noticed I wasn't full of my usual vitality and asked if there was anything wrong. I told him I was feeling anxious about turning thirty.

"When I met my wife and fell in love, which was the best time of my life."

"The Second World War came, and my wife and I had to flee Austria to save our lives. When we were together and safe on a ship bound for North America, which was the best time of my life. "

"When we came to Canada and started a family, which was the best time of my life."

"When I was a young father, watching my children grow up, that was the best time of my life."

"And now, Joe, 1 am seventy - nine years old. I have my health, l feel good and I am in love with my wife just as I was when we first met. This is the best time of my life."

BEIJING – Set off by the April 1 Sino – US plane collision and US official agreement of the biggest arms sale to Taiwan in a decade as well as remarks by US President Bush on defending Taiwan, there have been increasing hacker attacks on websites of the two countries in the past weeks.

An American group of hackers which calls itself Poizon Box had begun ruining Chinese web－sites after the April 1 spy plane incident, top Chinese Sina. com. said.

The Chinese soon attacked back.

On April 29, Chinese hackers invaded two US Government websites over the weekend, forcing the Department of Labor and the Department of Health and Human Services to shut down their sites for a short time.

The US Department of Labor went offline for a few hours after a page in its website was changed to display a picture of Wang Wei, the Chinese pilot who died in the collision.

The page was titled “China hack!” and read, in English, “The whole country is sorry for losing the best son of China-Wang Wei forever, we will miss you until the end of the day.”

On May 1, hackers exchanged bad remarks in which the official White House website was defaced(丑化) by a huge amount of e-mail garbage. On May 5, the White House website fell victim(受害者) to a denial(否定、拒绝) of service attack that blocked access(通道)to the site for more than two hours.

The Computer Network and Information Security Management Office told web operators an average of 100 sites a day had seen “some form of attack.”
