Ⅱ.阅读理解
It might seem hard to imagine that a bad tooth could be deadly.But doctors in the Washington area say a twelveyearold boy died last month of a tooth infection that spread to his brain.They say it might have been prevented if the boy had received the dental care he needed.
Experts at the National Institutes of Health say good dental care should start at birth.They say breast milk is the best food for the healthy development of teeth.Breast milk can help slow bacterial growth and acid production in the mouth.
When baby’s teeth begin to appear，you can clean them with a wet toothbrush.Dentists say it is important to find soft toothbrushes made especially for babies，and use them very gently.
The use of fluoride(氟化物) to protect teeth is common in many parts of the world.This natural element is often added to drinking water supplies.The fluoride mixes with enamel(釉质)，the hard surface on teeth，to help prevent holes，or cavities from forming.
But the American Academy of Pediatric Dentistry points out that young children often swallow toothpaste when they brush their teeth.The group notes that swallowing fluoridated toothpaste can cause problems.So young children should be carefully supervised when they brush their teeth.And only a small amount of fluoridated toothpaste，the size of a green pea，should be used.
Parents often wonder what effects sucking a thumb or sucking on a pacifier might have on their baby’s teeth.Dental experts generally agree that this is fine early in life.
The American Academy of Family Physicians says most kids stop sucking their thumbs by the age of four.If it continues，the group advises parents to talk to their child’s dentist or doctor.It could influence the correct development of permanent teeth.

Ⅲ.任务型读写
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，act and speak without thinking about the results of their behavior.These are among the signs named on the website 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 brainimaging 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 selfcontrol that mark A.D.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 is 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 are 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. Jack Wang is chairman of the Brookhaven 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.
