1、Passage 5Today anyone will accept money in exchange for goods and services. People use money to
buy food, furniture, books, bicycles and hundreds of others they need or want. When they work,
they usually get paid in money.
Most of the money today is made of metal paper. But people used to use all kinds of things as
money. One of the first kinds of money was shells. Shells were not the only things used as money.
In China, cloth and knives were used. In the Philippine Islands, rice was used as money. In parts of
Africa, cattle were one of the earliest money. Other animals were used as money too.
The first metal coins were made in China. They were round and had a square hole in the
center. People strung them together and carried them from place to place. Different countries have
used different metals and designs for their money. The first coins in England were made of tin.
Sweden and Russia used copper to make their money. Later, other countries began to make coins
of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper
money looked more like a note from one person to another than paper money used today.
Money has had an interesting history from the days of shell money until today.

Make rules for Internet use with your parents. For example, when you can go online, for how

information---your real name, home address, age, school, phone number or other personal
information.
Check with your parents before giving out a credit card number.
Never send a photo of yourself to someone in e-mail unless your parents say it‘s OK.
Check with your parents before going into a chat room. Different chat rooms have different

for you.
Never agree to meet someone you met on the Internet without your parent‘s permission.
Never meet anyone you met on line alone.
Always remember that people online may not be who they say they are. Treat everyone
online as strangers.
If something you see or read online makes you uncomfortable, leave the site. Tell a parent or
teacher right away.
Treat other people as you‗d like to be treated. Never use bad language. Remember—not
everything you read on the Internet is true.
