 Think of all the things you throw away:juice bottles,soda cans,candy covers.It  adds up.How much rubbish do you produce? Americans throw away about 1 ton of rubbish per person every year.That's 2000 pounds of rubbish! Most of the rubbish gets covered in big holes in the round called landfills(垃圾掩埋法).

    A lot of this rubbish can be recycled,or turned back to something useful.The main things we recycle today are made of metal and paper.

    People recycle for many reasons.One of the main reasons is to protect resources(资源).Making new cans out of old ones means less aluminum(铝) is needed for new cans.

    This leads to a second reason people recycle:it saves energy.Recycling old aluminum cans take much less energy than making new aluminum.To make new aluminum,you need to mine metal ore(矿石) from the ground,remove it,and refine it,into a finished metal.

    Recycling also protects valuable land.By recycling,we produce less rubbish.That means fewer landfills are needed for dropping our rubbish.Because metals are some what costly to make,they are the world's most recycled materials.About two-thirds of all steel(钢) is recycled.

    Almost all drink cans are made of aluminum.Americans recycle about one-third of their used aluminum cans.Empty cans are sent to special factories.There,they are cleaned,melted,and made into new pieces of aluminum.

    Americans use lots of paper — mostly in the form of newspapers,magazines,and cardboard boxes.In fact,paper takes up more space in landfills than any other material.

    Old paper can be cut and made are into new paper.Americans recycle a little more than one-third of their paper rubbish.New papers are made from trees,each ton of recycled paper saves about 17 trees!

When do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colorful plants and wild flowers?

The forest is a whole world of its own. It is full of many different living things(生物). But even though they are all different, they have one thing in common: they all need each other in order to live on.

The trees feed the forest “people” by making food in their leaves; by using sunlight to join water and minerals(矿物) from the soil and air. Their deep network of roots joins the soil together and stops it from dying out, making it possible for living things to live in it.

Human beings(人类) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks(售货员) to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mailmen, telephone operators, and many others.

We also need other human beings in another way. We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone.

Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else!
