In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes (性别) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.

Boys, for example, generally are better than girls at mathematical (数学的) ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.

What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神经) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation and the expression for emotions. In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by smaller nerves than the two sides of a woman’s brain area.
