共用题干Understanding Autism
1 Autism（孤独症）is a life-long developmental disability that prevents individuals from
properly understanding what they see,hear and other senses.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）show relatively even skill development.
Individuals with autism,however,typically show uneven skill development,with deficits（欠
缺）in certain areas一most frequently in their ability to communicate and relate to others一
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 perlorm 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.
