Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print?

      Paper was first created about 2,000 years ago, and has been made from silk, cotton, bamboo, and, since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren’t many hooks, few people learned to read.

      Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.

      Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD-ROMs or machines such as MP3 players.

      Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day? No, I don’t think the Yao Ming poster on my bedroom wall will ever be replaced by a computer two metres high!

 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!
