单选题 Do you believe that only boys do well in science? Does it seem to you that girls have better vocabularies than boys? In your opinion, are boys better at building things? If your answer to each of those questions is "Yes", you are right according to an article in Current Science. There are exceptions, but here are the facts. On the average, males score higher on tests that measure mathematical reasoning, mechanical ability, and problem-solving skills. Females show superior ability in tests measuring vocabulary, spelling, and memory. But these difference will probably not always exist. In the future, a person"s abilities may not be determined by sex. As one scientist says, "Nothing is impossible for a person to be or do." In several recent studies, young babies have been observed and tested to discover how different abilities are developed. A scientific team headed by Jerome Kagan, a psychologist at Harvard University, is studying the thinking ability of children 9 months old. The test is a simple one. The baby, while seated on its mother"s lap, watches a "show" on a theater stage. In act 1 of the show, an orange-colored block is lifted from a blue box and moved slowly across the stage. Then it is returned to the box. This is repeated six times. Act 2 is similar, except that the orange block is smaller. Baby boys do not seem to notice the difference in the size of the block, but girls immediately become excited and begin to make noises that sound like language. They seem to be trying to talk. It is known that bones, muscles, and nerves develop faster in baby girls. Usually, too, baby girls talk at an earlier age than boys do. Scientists think there is a physical reason for this. They believe that the nerve endings in the left side of the brain develop faster in girls than in boys. And it is this side of the brain that strongly influences an individual"s ability to use words, to spell, and to remember things. By the time they start to school, therefore, little girls have an advantage that boys do not have. Girls are physically more ready to remember facts, to spell, and to read. These, of course, are skills that are important in elementary school. But what have the boys been doing in the years before starting school? They have been developing something called aggression. An aggressive person has courage and energy. He feels strong and independent. He is often the first one to start a fight.
