题目内容
19．Children with autism （自闭症） have difficulty with social skills and communication．They often behave in limited and repeated ways and have unusual strong interests．Autism is more common in boys than girls．What causes it is not clear．Scientists are studying genes（基因） and possible environmental influences．
Doctors usually cannot confirm a diagnosis（诊断）of autism until a child is about three years old．Rebecca Landa is a professor and researcher in Maryland．Professor Landa wanted to find out what differences in development might be seen earlier．She led a new study that studied 235babies between six and 36months of age．
"At six months of age，some signs of the development of communication and social is slow，like when you lay your baby on their back and you pull them by the arms gently into a seated position，it seems hard for the baby to raise his/her head．That does not mean the baby is going to have autism，but it does mean the baby needs to have some exercises．And when they strengthen their body，they are able to play with toys and people and grow better．"
By the time a baby is one year old，signs of possible autism include difficulty in using words and not looking eye-to-eye or reaching out to other people．
By 14months，the baby might smile less and use language less．However，Professor Landa says these signs can be so small that they might be missed during a short health exam．
Professor Landa says，it's important for parents to care about their children's development．The earlier parents notice signs，the sooner they can begin doing simple things that may help improve their child's development，such as talking to the child about what they are doing，and playing simple games that keep the child's attention．
