Why do people cry? Scientists say the body produces tears because they need them. One kind of tears is for the eye, the other is for the heart. They both work as cleaners. If something else like dust(灰尘) gets into your eye, tears also come into the eye to clean it out. If you are hurt by something, your strong feelings produce some poisonous chemicals(毒素) in your body, and at the same time, tears come out with them. If these poisonous chemicals are not cleaned out of your body as soon as possible, they will do harm to the heart sooner or later.
In the United States men have heart problems more often than women do. Doctors say heart problems have something to do with the pressures(压力) of living and working now. Perhaps men suffer more from these illnesses because they do not cry enough. They need to cry more.
In fact, you can find many ways of reducing the pressures to keep fit. Crying is a natural and physical one.
Do you know that a student can produce up to 240 pounds of school waste and lots of waste gas (气体) during a term? This includes transportation, food, paper, pens, pencils and so on.
Transportation Some parents drive their kids to school every day. We all know waste gas from cars is a main cause air pollution. If parents who live in a neighborhood can take turns to drive their kids to school each day, that'll be better. Another way of going green is to walk to school if students live near their schools.
Food It's surprising that only one elementary school can produce up to 19,000 pounds of lunch waste each year. That's only one school. One way to help take care of the environment is to stop using plastic bags. There are all kinds of environmental boxes for students to put their food in.
Paper, pens and pencils Lots of paper is thrown away by American students. They throw away about 1.6 billion pens every year. They waste many pens and chemicals (化学药品) in them are bad for the environment. Many more pencils are thrown away than pens. Pencils are made from trees, so if more pencils are thrown away, more trees will be cut down. So students should reuse (再使用) paper, pens and pencils instead of throwing them away.
Backpacks As fashion comes and goes, almost every kid needs a new backpack every year. They can save lots of money and materials if they reuse the same schoolbags each year.
