[不定项选择题]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.

Ask three people to look out the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it.
Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a cyclist a ticket. Another may say that he sees a rush -hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow.
