It’s an age-old saying: Men are from Mars; women are from Venus. Males and females 　65 　different behaviors almost from　birth. Researchers say these behaviors are due to 　66 　differences in brain structure and activity. Studies show men are better at hitting targets (靶子)and solving math problems 　67 　women are better at memorizing words and 　68 　faces. Why the differences?

A test of the brain’s electrical activity shows that women commonly　use both sides of their brain while men rely more on one. Scientists already know that the two sides of the brain control different functions -one controlling the sense of space, 　69 , the other controlling language. Some researchers believe　that the different ways men and women use their brains 　70 　from ancient times, when cave men hunted and women 　71 　the children. Men had to have good aim. Women had to talk to the kids.

Whatever the 　72 , the battle of the sexes continues. And although their brains are constructed slightly differently, men and women may be equally　capable. They may simply 　73 　different abilities. Take a couple arguing over the location of their car in a parking lot. The man might use his sense of 　74　 　to find it, while the woman relies on her memory of landmarks. Both　of them find the car. But chances are, they’ll still argue about　who’s the better driver and who’s better at finding the way home.
