九年级英语单选题中等难度题查看答案及解析
Children with autism(孤独症) 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(确诊) 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.

Alfredo Moser is a Brazilian worker who is skilled at repairing machines. His wife says her husband has always been handy at home and made tables and chairs. Alfredo has invented a way of lighting his house during the day without electricity.
He has been using plastic bottles filled up with water and a little bleach(漂白剂) to provide dark rooms with light for many years. And the idea has now spread across the world. It is predicted that his lighting system, which works using refraction(折射) of the sunlight, will be fitted in over a million homes by the end of this year.
Alfredo used normal plastic drinks bottles that are often thrown away. The secret of the water in the bottles is the bleach added to water, which stops it turning green in the sunlight. Mr. Moser drills a hole in a roof tile and then pushes the bottle in from below, keeping the bottle in place with polyester resin (聚酯树脂). Depending on the strength of sunlight, the light fills his home, and the bottles are just like electric bulbs of between 40 and 60 watts.
Alfredo came up with the idea for his “Moser light’’ during one of the blackouts in Brazil in 2002. He said only factories had power in his home city, in southern Brazil during the energy shortage.
The local supermarket and his neighbors’ houses are using Moser lights. He earned a few dollars, but his invention has not made him a rich man. Now a great number of people admire what he is doing!
1.What did Alfredo’s wife think of him?
A. He was always busy repairing machines. B. He couldn’t do any housework.
C. He was clever with his hands. D. He is a helpful man to save our world.
2.The reason Alfredo put a little bleach into the bottle is_________________.
A. because the bottle can give more light.
B. because the bleach can keep the bottle in a roof tile.
C. because the bleach can protect water from turning green.
D. because the bleach can give out the sunlight.
3.Which of the following is TRUE according to the passage?
A. People can use Moser’s lights only at night.
B. Moser’s light gives too poor light.
C. Moser’s bottles use electricity to light the room.
D. Moser’s bottle light is a green idea.
4.The underlined word “blackouts” in the passage probably means “___________”.

A. Alfredo’s lights will be more and more popular.
