1. 儿童青少年运动员应该食用多样化的食物,其中,蛋白质应占膳食总能量的12%-15%,碳水化合物至少占55%,而脂肪至多占30%。日常生活中如何吃才能满足这些要求呢?膳食指南宝塔提供了一条可行之道。2.有些营养素对热爱运动的儿童青少年运动员非常重要,要保证摄入充足,这些营养素是碳水化合物(包括纤维素)、维生素B6、维生素D、铁、钙、镁、锌、铬。科学合理、包罗各类食物的平衡膳食,对青少年运动员最大程度地全面摄取各种营养素,满足生长发育和运动训练的需要,是非常必要的。3.鼓励儿童青少年运动员在运动训练前、中、后进行补液,以避免脱水的发生。4.如果膳食合理平衡,就没必要额外补充营养品。 相似文献

Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively. 相似文献

1.WTO与中国:挑战和机遇并存近年来,中国已崛起为世界上发展最快的大国。预期2002年的GDP将增长7.5~8个百分点。以欧洲的视角来看,中国社会正受益于一大批受过高等教育的技艺精湛的人才,他们不畏变革,勇于创新,乐于接受新技术。在这片土地上,变革被真正地看作一个坚实的文化特征,这或许得益于古老的亚洲传统哲学。中国将接受入世的挑战。这或许是漫长和艰难的过程,但终将使中国在市场经验中受益。中国入世将为世界大国注入重要内容。2.WTO与中国传媒产业中国传媒业对世界的开放将是中国在今后的数年里面临的最大… 相似文献

Jenny Morris, freelance researcher, David Abbott, research associate at the Norah Fry Research Centre at the University of Bristol, and Linda Ward, Director of the Norah Fry Research Centre at the University of Bristol, carried out research to look at whether the current system of legislation and regulation is adequately protecting and promoting the interests of disabled children placed at residential schools. This article summarises some findings from the research which investigated the decision-making processes leading to residential special school placements and explored the involvement of education and social services authorities after placements have been made. The research found that the needs of individual children are not central to these decision-making processes; and that the local authorities who make such placements do not pay sufficient attention to protecting and promoting children's educational or care needs once they have gone away to school. Jenny Morris, David Abbott and Linda Ward indicate some of the ways in which current practice could be improved; make recommendations for future developments; and call for further research into the role of special residential schools in the context of policy on educational and social inclusion. 相似文献
