Read “The Write Stuff” and answer questions 1 to 6.

The Write Stuff

　　Throughout history people have written with many different tools and on many different surfaces.

　　PAPYRUS

　　Papyrus was one of the earliest known writing surfaces. For almost 4000 years papyrus was the main writing material used in the Middle East and around the Mediterranean. The Egyptians first made papyrus from the stem of the papyrus plant which grew along the banks of the River Nile.

　　1．Papyrus was made by cutting a papyrus stem into thin strips.

　　2．Two layers of strips were then pressed together until they stuck.

The Egyptians wrote on papyrus with brushes.

　　ANIMAL SKINS

　　When papyrus became scarce, people used animal skins to write on. This was called parchment. It was made from sheep skin which was washed, scraped, stretched and dried.

　　Parchment had a very smooth writing surface. It was used in Europe until the late Middle Ages.

　　Scribes wrote on parchment with quill pens made from goose feather.

　　PAPER

　　Around AD 105, a Chinese official called Cai Lun invented a new writing material made from old rags. This was known as paper. Paper is still made approximately the same way today as it was by Cai Lun, except that now machines are used.

PEN POWER

　　The problem with quill pens and later metal pens was that they had to be dipped in ink every few seconds. In the 19th century fountain pens were invented. These had a container for ink inside them－no more dipping or dripping!
