    Understanding Autism
　　1 Autism （孤独症)is a life-long developmental disability that prevents individuals from properly understanding what they see，hear，and otherwise sense.

　　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”。

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.

　　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.
