Natural ways of keeping time

In ancient times, people had to use the sun and the moon to tell time. They got up when the sun came up and worked in the fields until the sun went down.

Man-made things

The sand clock is made of two glass balls joined by a narrow neck. The top ball was filled with sand. The sand slowly moved through the neck into the bottom ball. People knew how much time had passed when all the sand had fallen to the bottom ball.

People also made the water clock. They made a small hole near the bottom of a pot. Then they filled the pot with water. Markings inside the pot showed how much time passed as the water dripped (滴) out of the hole.

Throughout history, people have been interested in knowing how languages first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about 3,000 languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers.

There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 yeas ago.

Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even died out completely. About 1,000 years ago, English was a little-known relative of German spoken on one of the borders of Europe.
