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.

Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s．Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women．Right? Wrong．Men and women always score similarly on intelligence tests, despite the difference in brain size．Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain．The brain consists of “grey matter” and “white matter”．While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes．

It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women．This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time．When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time．

There are other important differences between two sexes．As white matter is the key to spatial（空间的） tasks, men know better where things are in relation to other things．“A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher．That may explain one of life’s great mysteries: why men refuse to ask for directions…and women often need to!

The differences begin when fetuses（胎儿） are about nine weeks old, which can be seen in the action of children as young as one．A boy would try to climb a barrier （障碍物） before him or push it down while a girl would attract help from others．These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills．It may all go back to our ancestors（祖先）, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research．

If all this disappoints you, it shouldn’t．“The brain changes throughout our lives according to what we do with it．” says a biologist．

A．Women prefer doing many things at a time．        

B．Men do better dealing with one job at a time．

C．Women do not need to tell directions．
