单选题 Imagining being asked to spend twelve or so years of your life in a society which consisted only of members of own sex, how would you react? Unless there was something definitely wrong with you, you wouldn't be too happy about it, to say the least. It is all the more surprising therefore that so many parents in the world choose to impose such abnormal conditions on their children conditions which they themselves wouldn't put up with for one minute! Any discussion of this topic is bound to question the aims of education. Stuffing children's heads full of knowledge is far from being foremost among them. One of the chief aims of educations is to equip future citizens with all they require to take their place in adult society. Now adult society is made up of men and women, so how can a segregated school possibly offer the right sort of preparation for it? Anyone entering adult society after years of segregation can only be in for a shock. A co-educational school offers children nothing less than a true version of society in miniature. Boys and girls are given the opportunity to get to know each other, to learn to live to gather from their earliest years. They are put in a position where they can compare themselves with each other in terms of academic ability, athletic achievement and many of the extra-curricular activities which are part of school life. What a practical advantage it is (to give just a small example) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense co-education makes of the argument that boys are cleverer than girl or vice-versa. When segregated, boys and girls are made to feel that they are a race apart. Rivalry between the sexes is fostered. In a coeducational school, everything falls into its proper place. But perhaps the greatest contribution of co-education is the healthy attitude to life it encourages. Boys don't grow up believing that women are mysterious creatures—airy goddesses, more like book-illustrations to a fairy-tale, than human beings. Girls don't grow up imagining that men are romantic heroes. Years of living together at school dispel illusions of this kind. There are no goddesses with freckles, pigtails, piercing voices and inky fingers. There are no romantic heroes with knobbly knees, dirty fingernails and unkempt hair. The awkward stage of adolescence brings into sharp focus some of the physical and emotional problems involved in growing up. These can better be overcome in a co-educational environment. When the time comes for the pupils to leave school, they are fully prepared to enter society as well-adjusted adults. They have already had years of experience in coping with many of the problems that face men and women.

单选题 Musicians-from karaoke singers to professional violin players-are better able to hear targeted sounds in a noisy environment, according to new research that adds to evidence that music makes the brain work better. 'In the past ten years there's been an explosion of research on music and the brain,' Aniruddh Patel, the Esther J. Burnham Senior Fellow at the Neurosciences Institute in San Diego, said today at a press briefing. Most recently brain-imaging studies have shown that music activates many diverse parts of the brain, including an overlap in where the brain processes music and language. Language is a natural aspect to consider in looking at how music affects the brain. Patel said. Like music, language is 'universal, there's a strong learning component, and it carries complex meanings.' For example, brains of people exposed to even casual musical training have an enhanced ability to generate the brain wave patterns associated with specific sounds, be they musical or spoken, said study leader Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University in Illinois. Kraus' previous research had shown that when a person listens to a sound, the brain wave recorded in response is physically the same as the sound wave itself. In fact 'playing' the brain wave produces a nearly identical sound. But for people without a trained ear for music, the ability to make these patterns decreases as background noise increases, experiments show. Musicians, by contrast, have subconsciously trained their brains to better recognize selective sound patterns, even as background noise goes up. At the same time, people with certain developmental disorders, such as dyslexia (阅读障碍症), have a harder time hearing sounds amid the noise-a serious problem, for example, for students straining to hear the teacher in a noisy classroom. Musical experience could therefore be a key therapy for children with dyslexia and similar languagerelated disorders, Kraus said. In a similar vein, Harvard Medical School neuroscientist Gottfried Schlaug has found that stroke patients who have lost the ability to speak can be trained to say hundreds of phrases by singing them first. In his research, Schlaug demonstrated the results of intensive musical therapy on patients with lesions (损伤) on the left sides of their brains, those areas most associated with language. Before the therapy, these stroke patients responded to questions with largely incoherent sounds and phrases. But after just a few minutes with therapists, who asked them to sing phrases and tap their hands to the rhythm, the patients could sing 'Happy Birthday,' recite their addresses, and communicate if they were thirsty. 'The underdeveloped systems on the right side of the brain that respond to music became enhanced and changed structures,' Schlaug said. Overall, Schlaug said, the experiments show that ''music might be an alternative medium for engaging parts of the brain that are otherwise not engaged. '
