问题    Adam Walden’s best friend is his cello-and that’s just fine with him. Like all children with autism and related disorders, the 8-year-old boy from Los Angeles has trouble interacting with others and forming relationships. Learning to speak has been an enormous challenge for him and, at an age when many kids are being scolded for chatting in class, Adam sometimes has problems even recognizing the human voice.
   Once regarded with suspicion by his classmates, Adam rarely got invited to birthday parties and during those few occasions that he was asked, he was often found hiding under beds or running away down the street. But life took a positive turn for Adam once he was introduced to the cello. Recently admitted to the Colburn School of Performing Arts, Adam has learned to communicate with others through his music and performs regularly in recitals, where he hams it up and loves to be on stage.
After more than four years of intensive therapy and treatments, Adam has reached the point where most people who meet him would at first just think he’s a little eccentric or different. But, as many experts point out, autism is not simply "quirkiness" or an unusual personality trait, but a serious disorder capable of destroying families and children’s futures. Like others with the condition, Adam’s progress has been bard-won.
   His struggles are increasingly shared by many across the United States as rates of autism continue to skyrocket. Some experts estimate that as many as 1 in 166 children born today will be diagnosed with an autistic disorder. Autism is now the second most commonly diagnosed developmental disability in children after mental retardation.
   While the causes for the dramatic rise in cases over the past decade are the subject of much debate, one thing is certain: early diagnosis is crucial. By being aware of key symptoms to watch for, parents can help spot the disorder and, if necessary, ensure their child begins treatment.
   "One of the factors in a good [autism] prognosis is early intervention," says Dr. Sally Ozonoff, associate professor of psychiatry at the MIND Institute at the University of California, Davis. "It’s been shown pretty clearly that starting an intervention at age 3 is better than 5, or starting intervention at 2 or potentially even earlier than that is better."
   But while most experts agree that beginning treatment for autism at an early age is important, the process of diagnosing children can be fraught with difficulty and makes the goal of early treatment sometimes easier said than done. [br] Which of the following can be inferred from the passage?

选项 A、After five years of intensive treatment, Adam has completely recovered.
B、Mental retardation can result in autism.
C、Parents should know some key symptoms of autism so that they can spot the disorder.
D、Diagnosing autism in children is not difficult.

答案 C

解析推理题。文章第五段提到：“By being aware of key symptoms to watch for，parents can help spot the disorder and，if necessary，ensure their child begins treatment．”(父母留心儿童孤独症的一些主要症状可以使他们帮助医生诊断出孩子的病症，而且如果有必要，保证孩子能开始接受治疗。)，而A、B、D三个选项与文章的内容有严重出入，所以正确答案是C。
