1 Autism （孤独症)is a life-long developmental disability that prevents individuals from properly understanding what they see，hear，and otherwise sense. This results in severe problems of social relationships，communication，and behavior. Individuals with autism have to painstakingly '（费力地)learn normal patterns of speech and communication，and appropriate ways to relate to people，objects，and events，in a similar manner to those who have had a stroke.
2 The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic （遗传的)factors may sometimes be involved. Autism may indeed result from a combination of several “causes”。
3 Most people with mental retardation （智力迟钝的)show relatively even skill development. Individuals with autism，however，typically showwww.med126.com
uneven skill development，with deficits （~欠缺)in certain areas - most frequently in their ability to communicate and relate to others - and distinct skills in other areas. It is important to distinguish autism from mental retardation or other disorders，since diagnostic （诊断的)confusion may lead to inappropriate and ineffective treatment techniques.
4 In general，individuals with autism perform best at jobs which are structured and involve a degree of repetition. Some people who have autism are working as artists，piano tuners，painters，farm workers，office workers，computer operators，dishwashers，assembly line workers，or employees of sheltered workshops or other sheltered work settings.

第一篇 Calling for Safe Celebrations
Last Fourth of July，Pete，a 14-year-old boy，was enjoying the lit-up skies and loud booms from the fireworks （烟花)being set off in his neighborhood. Suddenly，the evening took a terrible turn. A bottle rocket shot into his eye，immediately causing him terrible pain His family rushed him to the emergency room for treatment. As a result of the injury，Pete developed glaucoma （青光眼)and cataracts （白内障)。 Today，Pete has permanent vision loss in his injured eye because of his bottle rocket injury.
June is Fireworks Eye Safety Awareness Month，and through its EyeSmart campaign the American Academy of Ophthalmology （眼科学)wants to remind consumers to leave fireworks to professionals （专业人员)。 “There is nothing worse than a Fourth of July celebration ruined by someone being hit in the eye with a bottle rocket，” said Dr John C. Hagan，clinical correspondent for the Academy and an ophthalmologist at Discover Vision Centers in Kansas City. “A safe celebration means letting trained professionals handle fireworks while you enjoy the show.”
According to the U.S. Consumer Product Safety Commission，more than 9，000 fireworks-related injuries happen each year. Of these，医学全.在线www.med126.com
nearly-half are head-related injuries，with nearly 30 percent of these injuries to the eye. One-fourth of fireworks eye injuries result in permanent vision loss or blindness. Children are the most common victims of firework abuse （伤害)，with those fifteen years old or younger accounting for 50 percent of fireworks eye injuries in the United States. Dr Hagan estimates that his practice sees more than 30 injuries each year from fireworks.
Even fireworks that many people consider safe represent a threat to the eyes. For children under the age of five，apparently harmless sparklers （花炮)account for one-third of all fireworks injuries. Sparklers can burn at nearly 2，000 degrees Fahrenheit （华氏)。
