Recently, we have had a discussion in our class about whether parents are our best teachers . Some students
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.

In a few years, you might be able to speak Chinese, Korean, Japanese, French, and English -- and all at the same time. This sounds incredible, but Alex Waibel, a computer science professor at US' s Carnegie Mellon University (CMU) and Germany' s University of Karlsruhe, announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.
One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.
Another prototype (雏形机) can send translations of a speech to different listeners depending on what language they speak. "It is like having a simultaneous translator right next to you but without disturbing the person next to you," Waibel said.
Prefer to read? So-called Translation Glasses transcribe (转录) the translations on a tiny liquid-crystal(液晶) display (LCD) screen.
Then there' s the Muscle Translator. Electrodes (电极) capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted (植入) in a person' s face, according to researchers.
During a demonstration (演示) held last Thursday in CMU' s Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed -- without speaking aloud -- a few words in Mandarin(普通话) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: "Let me introduce our new prototype".
This particular gadget (器械), when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, "to switch your mouth to a foreign language". "The idea behind the university' s prototypes is to create 'good enough' bridges for cross-cultural exchanges that are becoming more common in the world," Waibel said.
With spontaneous (自发的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.
