　　28、D) They should see to it that their children have adequate sleep.

　　Reducing the amount of sleep students get at night has a direct impact on their performance at school during the day. According to classroom teachers, elementary and middle school students who stay up late exhibit more learning and attention problems. This has been shown by Brown Medical School and Bradley Hospital research. In the study, teachers were not told the amount of sleep students received when completing weekly performance reports. Yet they rated the students who have received eight hours or less as having the most trouble recalling old material, learning new lessons, and completing high quality work. Teachers also reported that these students had more difficulty paying attention. The experiment is the first to ask teachers to report on the effects of sleep deficiency in children. Just staying up late can cause increased academic difficulty and attention problems for otherwise healthy while functioning kids, said G. F., the studys lead author. So the results provide professionals and parents with a clear message: when a child is having learning and attention problems, the issue of sleep has to be taken into consideration. If we dont ask about sleep and try to improve sleep patterns in kids struggling academically, then we arent doing our job, F said. For parents, he said, the message is simple. Getting kids to bed on time is as important as getting them to school on time.

　　26. What were teachers told to do in the experiment? C. Record students weekly performance.

　　27. According to the experiment, what problem can insufficient sleep cause in students? B. Lack of attention.

　　28. What message did the researcher intend to convey to parents? D. They should see to it that their children have adequate sleep.

　　P. P never wanted to be a national public figure. All she wanted to be was a mother and a homemaker. But her life was turned upside down when a motorist distracted by his cell phone, ran a stop sign and crashed into the side of her car. The impact killed her two-year-old daughter. Four months later, P. reluctantly but courageously decided to try to educate the public and to fight for laws to ban drivers from using cell phones while a car is moving. She wanted to save other children from what happened to her daughter. In her first speech, P. got off to a shaky start. She was visibly trembling and her voice was soft and uncertain. But as she got into her speech, a dramatic transformation took place. She stopped shaking and spoke with a strong voice. For the rest of her talk, she was a forceful and compelling speaker. She wanted everyone in the audience to know what she knew without having to learn it from a personal tragedy. Many in the audience were moved to tears, and to action. In subsequent presentations, P. gained reputation as a highly effective speaker. Her appearance on a talk show was broadcast three times transmitting her message to over 14,000,000 people. Her campaign increased public awareness of the problem and prompted over 300 cities and several states to consider restrictions on cell phone use.

　　Many people catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why cant they find a cure for the common cold? The answer is easy. Therere actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isnt a cure for each one. When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a blockage in it. You feel terrible because you cant breathe well. But your body is actually eating the virus. Your temperature rises and you get a fever. But the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells. You may feel miserable but actually your wonderful body is doing everything it can to kill the cold. Different people have different remedies for colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids. Other people take medicines to relieve various symptoms of colds. Theres one interesting thing to note. Some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesnt develop a way to fight it and kill it.
