一位心理学家说:“一个人所发挥的能力,只占他全部能力的4%。”这告诉我们（   ）

    Sport is not only physically challenging, but can also be mentally challenging. Criticism from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.

    The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches' criticisms to heart and find faults in themselves.

    Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today's youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find faults with youngsters' performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

阅读《谈友善》，完成问题。
                                                                                                                            谈友善
         ①日常生活中不难看到这样的情景：有的人因为一些鸡毛蒜皮的小事便恶语相向，甚至动起手来；有的人缺乏同情心，在别人遇到困难时无动于衷；还有的人能关爱家人和朋友，但对其他人却漠不关心……这些现象都是缺乏友善之心的表现，既有悖于中华民族的传统美德，也不符合现代文明的发展方向。人是社会关系的总和，在生活和工作中对人友善，是公民应具备的基本道德素养。《公民道德建设实施纲要》也把“友善”作为基本道德规范之一。因此，我们有必要在全社会倡导友善。
        ②友善，意味着宽以待人，不苛求于人，不强加于人。友善待人，表明人胸怀宽广，精神境界纯洁高尚。友善待人，是中华民族的传统美德之一，古代贤哲对这个问题有过许多精辟的论述。孔子明确提倡“         【甲】         ”，荀子则更强调了友善的重要，他说：“与人善言暖若锦帛，与人恶言深于矛戟。”一个人友善待人，人必友善待他，这样，才有助于成就大事业，整个社会氛围才会和谐，社会总体效率才会提高。可以说，一个充满友善的世界才是美好的世界。
        ③友善，还意味着乐于助人，互爱互助。对处于困境中的人伸出援助之手，发扬友爱互助精神，人间就会充满美好的真情。近年来，我国广大人民群众开展了各种互帮互助活动，如“希望工程”“送温暖”活动等等，使传统美德在新的历史条件下得到发扬光大。被誉为“当代雷锋”荣获“感动中国人物”称号的鞍钢集团矿业公司职工郭明义，几十年日一日，鲜血捐款，为有困难的人排忧解难；他在解释自己的行为时高兴地说“          【乙】        ”。不胜枚举的好人好事充分体现了社会主义大家庭的和谐人际关系，促进了社会主义精神文明的建设。
        ④对亲人、好友、同事友善，也许不难，但能以友善之心对待陌生人，却并非易事。我们倡导的友善，其理想境界是广具爱心。“          【丙】         ”，“四海之内皆兄弟”，只有推己及人，普施善心，广推善举，我们的社会才会充满温馨和谐。
        ⑤友善是和平的使者。在经济全球化、人际交往日趋频繁的今天，让我们共同努力，以取得谐调的发展。
