71   People traveled in search of food and shelter or in order to flee from their enemies. Sometimes they were looking for gold or silver in order to become rich. On other occasions they were searching for rich farmland.

This is not to say that no one ever traveled just for fun. Even in ancient times, some pleasure travel occurred. During a typical season, 700,000 tourists would crowd into the ancient city of Rome, where animals performed and magicians entertained them.    72  

    73    International tourist arrivals alone reached as many as 546 million in 1994 and are forecast to rise to 937 million in 2010, according to the World Trade Organization.

   74    Probably the most common reason for traveling is related to our physical well – being. Actually, traveling to sports events is one of the fastest growing types of travel. In our fast developing society where stress has become part of people’s life, people can rest and relax by having a change of environment and activities.

   75    No one seems to doubt that travel broadens the mind. In 18th century Europe, young men would go on a Grand Tour to various countries in order to complete their education. Today the desire to travel to different countries is encouraged by modern mass media. People who travel to other counters can at the same time learn more about their own country and culture.

 A．But why do people like traveling so much?

 B．Throughout history, most travel was not for pleasure.

 C．So they travel to a lake for a swim or to a park for a hike.

 D．The improvement in transportation has also encouraged people to travel

 E.  Wealthy Romans made trips to Greece to take part in the Olympic Games.

 F．The growth of tourism has become a modern phenomenon experienced by all countries in the

    world.

 G．Another important reason for traveling is to satisfy our curiosity about different places and

    cultures.

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.

Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.

Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.

The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.

Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.

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 (銅) 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.

A．The first coins in England were made of tin (錫).

B．But people used to use all kinds of things as money.

C．No one knows for certain when people began to use money.

D．People strung (串連) them together and carried them from place to place.

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

F. They began to use paper money.

G. Today anyone will accept money in exchange for goods and services.

Recently 3 kinds of foods are very popular in the US.

Convenience Foods

Instead of buying only fresh foods, Americans buy many more convenience foods. These are foods which are ready partly or completely prepared. There are also many canned convenience foods, such as soups and vegetables.

Convenience foods save time and trouble. They are popular with people who are busy or who don't like cuisine or washing dishes. But they often cost more money than fresh, unprepared foods and may contain man-made additives. Also they don't taste as good as home cooked foods.

Health Foods

In the 1960s, a "back-to-the earth" movement was started by young people in the US. The movement was a reaction against the harmful effects of technology. Many people now prefer natural and organic foods to the prepared foods sold in food stores.

Diet Foods

These, days Americans are more and more concerned with their weight. American supermarkets sell a variety of diet foods as diet soft drinks, diet candy, and diet salad dressings. Each year dozens of new diets are popularized. However, some of the diet foods are unbelievable. There are tricks in their advertisements.
