B Are you carrying too much on your back at school? You’re not alone. Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags) “It hurts my back when I run,”said Oberlin Reyes, a student in Virginia. “It’s hard to go up the stairs with my backpack,because it’s too heavy,” Oberlin was among students whose backpacks were weighed for a week in a recent study. They had regular backpacks with two straps(带子)to carry them, but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground). Shirley Park, whose backpack weighed 10 kilograms,said she changed to a rolling backpack because she was starting to have back pain. How much is too much?Experts say students should carry no more than 10 to 15 percent of their own body weight. A few students had one suggestion to lighten the load:less homework. P.S.( 附)Doctor’s suggestion: 1 Lighten the load. Clean out binders(活页材料)and take home only the books you need that night. 2 Wide straps are better. They send out the weight over your shoulders more evenly(均匀)。 And be sure to wear both straps rather than hanging the pack over one shoulder. 3. Pack smart. The heavier things should be packed closed to the back. 4.Bend both knees when you pich up the pack ,and don’t just bend over at the waist.(腰) 6、“_________”is the main idea of the text.

A may lighten their backpacks B can learn how to help themselves C may feel their backpacks are lighter D will know how to wear backpacks C Now satellites(卫星)are helping to forecast(预报)the weather. They are in space and they can reach any part of the world.The satellites take pictures of the atmosphere(大气), because this is where the weather forms(形成)。They send these pictures to the weather station. So meteorologists(气象专家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change. Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures,the meteor- ologists compare(比较)them with earlier ones. Peerhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change,too. In their next weather forecast, the meteorologists can say this. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon,perhaps , they may be ablet to forecast the weather for a week or more ahead(提前) 11 Satellites travel__________.
