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.

If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can’t understand speakers from other parts.

Ravens（渡鸦） are like superheroes．

To us it seems so natural to put up an umbrella to keep the water off when it rains．But actually the umbrella was not invented as protection against rain．Its first use was as a shade against the sun．
Nobody knows who first invented it, but the umbrella was used in very ancient times．Probably the Chinese were the earliest to use it in the eleventh century BC．We know that the umbrella was used in ancient Egypt and Babylon as a sunshade．And there was a strange thing connected with its use: it became a symbol of honor and authority．In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high offices．
In Europe, the Greeks were the earliest to use the umbrella as a sunshade．And the umbrella was allowed in common use in ancient Greece．But it is believed that the earliest persons in Europe to use the umbrella as protection against rain were the ancient Romans．
During the Middle Ages, the use of the umbrella practically disappeared．Then it appeared again in Italy in the late sixteenth century．And again, it was considered a symbol of power and authority．In around 1680, the umbrella appeared in France and later on in England．
By the eighteenth century, the umbrella was used against rain throughout most of Europe．Umbrellas have not changed much in style during all this time, though they have become much lighter in weight．It wasn’t until the twentieth century that women’s umbrellas began to be made in a whole variety of colors．
