Some people think that they will get ill if they use their brains（大脑）too much.  It is not true.  Through many researches, scientists show us that the more you use your brains, the better they will be, and the wiser you will become.

Of course, if you want to keep your mind clear and be energetic（充满活力的）, you must take a proper rest and study properly.  To the teenagers, using their brains in the morning is good for their health.

There are many ways to rest.  One is a peaceful rest.  Sleep is a peaceful rest.  Another is an active rest.  For example, take a walk outdoors, do morning exercises every day.  To change the way of the brains’activities（活动）is also a good way to rest.

In everyday life, to eat some eggs, meat, fresh vegetable and fruit is also good for the brains.

Wish you a wise man and a happy life.

The old saying “An apple a day keeps the doctor away” is not silly as some people think. The body needs fruit and vegetables because they contain vitamin C Many people take extra vitamins in the form of pills(药丸), believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins. So why waste money on them?

71  People use money to buy food, furniture, books, bicycles and hundreds of other things they need or want. When they work, they usually get paid in money.

Most of the money today is made of metal or paper.    72 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 for a long time. Elephant tusks, monkey tails and salt were used as money in parts of Africa.

The first metal coins were made in China. They were round and had a square hole in the centre. 73    Different countries have used different metals and designs for their money. 74  Sweden and Russia used copper (铜) to make their money. Later some 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.  75   The first paper money looked more like a note from one person to another than the paper money used today.

Money has had an interesting history from the days of shell money until today.

E. Money, as we know, is all made of paper.
