Children with autism(孤獨(dú)癥) have difficulty with social skills and communication. They often act in limited and repeated ways and have what seem like unusual strong interests.

Autism is more often seen in boys than girls. What causes it is not clear. Scientists are studying DNA and possible environmental influences.

Doctors usually cannot confirm a diagnosis(確診) of autism until a child is about three years old. Rebecca Landa is a researcher at the Kennedy Krieger Institute. Professor Landa wanted to find out what differences in development might be seen earlier. She led a new study that observed 235 babies between 6 and 36 months of age.

“At six months of age, when you lay your baby on their back and you pull them by the arms gently into a seated place, the baby’s head may nod back behind the shoulders, like poor head control. But that does not mean that the baby is going to have autism. It does mean the baby needs to have some exercises to help their body get stronger. And when the babies strengthen their bodies, they are better able to play with toys and also with people, which will help them have better outcomes.”

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 14 months, the baby might smile less and use language less. However, Professor Landa says these signs can be very small and their children might be missed during a short health exam.

“It’s important for parents to pay attention to their children’s development, and if they care about a child’s development, they should listen to experts.”

The earlier parents notice delays, she says, the sooner they can begin simple things that may help improve their children’s development. For example, they can talk to the children about what they are doing, give opinions when the children show them something, and play simple games that keep the children’s attention.

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window every afternoon, sewing or reading.

As several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn’t wash her window. It really looks terrible.”

One bright morning, I decided to clean my flat, including washing the window inside.

Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!

Then it dawned on me. I had been criticizing (批評(píng)) her dirty window, but all the time I was watching hers through my own dirty window.

That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings

Since then, whenever I wanted to judge (評(píng)判) someone, I asked myself first, “Am I looking at him through my own dirty window”

Then I try to clean the window of my own world so that I may see the world about me more clearly.

1.Why couldn’t the writer see everything clearly through the window?

A. Because the woman’s window was dirty.

B. Because the writer’s window was dirty.

C. Because the woman lived nearby.

D. Because the writer was near-sighted.

2.The writer was surprised that .

A. the woman was sitting by her window

B. the woman’s window was clean

C. the woman did cleaning in the afternoon

D. the woman’s window was still terrible

3.The underlined sentence “it dawned on me” probably means “ ”.

A. I began to understand it

B. it cheered me up

C. I knew it grew light

D. it began to get dark

4.What can we learn from the passage?

A. One shouldn’t criticize others very often.

B. One should often make his windows clean.

C. One must judge himself before he judges others.

D. One must look at others through his dirty windows.
