Part 3: Read the passage and decide which is the best answer. Circle the letter A, B, C or
D next to the word you choose.
Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing
material more than 5000 years ago. The Chinese invented the paper that we use 2000 years
ago.
A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers
used in paper, however, are plant fibers, and there are millions of them in one sheet. In
addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the
paper different colors; resin may add weight and texture.
Where do these fibers come from ? The majority of paper is made from the plant fiber
that comes from trees. Millions are cut down, but new trees are planted in their place. Paper
may be also made from things like old rags or pieces of cloth. Wastepaper, paper that has
been made and used, can be turned into recycled paper. This recycling process saves forest,
energy and reduces air and water pollution.
