1、 Are you carrying too much on your back at school? You're not alone. Back experts in the USA were worried that young students are having back and neck problems becau they are carrying too much in their backpacks（schoolbags）.
"It hurts my back when I run, "said Ebelin Reyes, a student in Virginia."It's hard to get up the stairs with my backpack becau it's too heavy. "
calendaryear Students have to carry heavy backpacks on their backs for a whole week's study. Ebelin is one of them. They have regular backpacks with two straps（带子）to carry them, but a number of students with heavy loads have switched to rolling backpacks. The backpacks have wheels and can roll on the ground.
Shirley Park's backpack weighs 10 kilos, and she said, "I'll change to a rolling backpack becau I am starting to have back pain."
How much is too much? Experts say that students should carry no more than 10 to 15 percent of their own body weight. A few students have had a good idea to lighten the load: less homework.
Doctor's suggestions:
1. Lighten the load. Take home only the books the students need that night.
2. Wide straps are better. They can nd out weight over your shoulders and be sure to wear backpacks with two straps.
3. The heaviest things should be packed clost to the back.
4. Bend both knees when you pick up the pack, don't just bend over the waist.

2、Imagine your sitting on your front garden admiring the shining sun when your neighbor comes with that annoying car with theface shield noisy sound and the exhaust pipe blowing out this horrible black smoke. What are you going to do about it?
In our modern days, too many people depend on their cars to get to work or to drop off their children to school. However, is it safe to have an increasing number of cars on our roads?pdpc
Rearch shows that cars create rious pollution. Exhaust from all combustion engines produces harmful effects on the health of both car urs and all innocent walkers. Cities have become islands of toxic chemicals from the unrestrained u of vehicles burning fossil fuels. The harmful health effects of car exhaust are pervasive and difficult to measure. For example, people with asthma would suffer with attacks due to the pollution. The world wild life also suffers from the cars' toxic emissions. No matter how much manufacturers try to make cars environmentally friendly, it will damage our earth in one way or another.
Additionally, cars are too dangerous for our community. Careless drivers put themlves and others in danger. Cars are critical to walkers especially to children if the driver is not looking on the road or somehow distracted. Have you known someone who toes or feet have been run over by cars while crossing the street?
Lastly, cars create social problems, which could lead to poor health. A few drivers suffer "Road Rage" and put themlves, loved ones and others in a threatening situation. Some
cars create disturbing nois, which disturbs people living near highways, freeways, etc. not to get enough sleep. People depend on their cars so much they forget to exerci their bodies and end up being obe or having a heart problem.
As a result of the excessive number of cars on our roads, everyone's life is in danger. In order to create an environmentally friendly and safe world, it is necessary for each country to limit the permits in number to control regional air pollution. Second, car manufacturers should try to improve the efficiency of vehicles, such as finding solutions to emissions of combustion engines, developing new power sources such as new fuels, natural gas. Third, try to improve efficiency of traffic by tting up dedicated bus lanes and giving priority to car-pools and vehicles with 3 or more pasngers. Besides, traffic can be scheduled; for example, commercial traffic at night; large companies can shift working hours and decentralize administrative operations.
