    My earliest memory of dad is grabbing (抓住) his hand while we walked together. As I 1 older, I remembered my father and I listened to many basketball games on the radio. I always fell asleep 2 the game was over. When I woke up in the morning, the score sheet (计分表) with the3score on it would be lying next to me. I'll always remember that.
    On cold mornings my father would drive his bread truck by the house. I used to ride on the floor of that bread truck as he delivered (分送) the bread to the stores. The 4 and the warmth from the bread made me hungry and kept me warm. I'll always remember that.
    My father would attend all my games. One night before an important game my father told me5 that he wouldn't be able to watch the game because he had to deliver the bread and it was a three-hour6from his route. The next day as the game time drew near, I thought about my dad. I happened to look across the field and  7saw his bread truck pulling into the stadium. He tried to make the game. I'll always remember that.
    Years later I became a teacher. I'll never forget the voice on the phone early one morning telling me dad had just been killed in a traffic accident. I could hear my heart beat in my ears. I 8up the phone and went back to my bedroom. After that nothing was very important to me. One day I was on the playground when a little boy walked up to me and grabbed my hand. His hand held mine the9  way I used to hold my father's by the last two fingers. At that moment I found my 10 in life again. You see even though my father was gone, he left something with me. He left me his smile, spirit and touch. My purpose was to use those gifts as he did. From that day I started. I'll always remember that!

莫扎特的力量

马永恒译

    ①今年是莫扎特诞辰250周年,世界各地的人们都在纪念他。而在过去十年中,人们一直在为莫扎特的乐曲对多种疾病的神奇疗效而惊叹。

    ②为什么莫扎特的乐曲成了人们关注的焦点,而不是巴赫、贝多芬或是肖邦的呢?美国一位研究癞痫症的神经科医师约翰·休斯认为,莫扎特乐曲的治疗效果与众不同。研究表明,80%的癞痫症患者因为病房内播放莫扎特D大调交响曲,其痉挛的强度减弱,频率降低,而用其他作曲家的乐曲进行类似的实验,却总是瞎子点灯——白费蜡。

    ③约翰·休斯认为,其奥妙在于莫扎特乐曲中旋律重复的独特方式。莫扎特乐曲中的旋律每20~30秒重复一次,这恰好与我们的脑电波及人体其他中枢神经系统的运行有着几乎一致的频率。于是,莫扎特乐曲中的节拍能够对癞痫病人大脑中不规则的电波起到纠正的作用。他接着解释,癞痫病人在病情发作时是完全昏迷的。可见,莫扎特的乐曲对大脑有直接影响。

    ④莫扎特的乐曲可以提高智障儿童智力的现象,是目前人们关注最多的。研究发现,智障儿童在聆听莫扎特乐曲10分钟后,可以在智力测验中拿到更多的分数。同样,反复并持续听过莫扎特某一段交响曲的老鼠,在一个复杂的容器中找到出口的速度,要比生活在其他环境中的老鼠快得多。

    ⑤此外,莫扎特的乐曲也能够对孤僻症患者起到很好的治疗作用。麦乐佳顿的女儿是个孤僻症患者,医生对她采用了音乐疗法。她接受治疗时使用的耳机是经过改装的,这种耳机的工作原理是通过震动头部骨骼的方式传导乐曲。莫扎特的乐曲会给患者的听觉以极大的冲击力,这样,借助音乐的力量,改善了患者与别人交流的能力。麦乐佳顿起初对此种疗法抱有怀疑,但是现在她的看法完全改变了。

    ⑥巴黎艺术家卡迪艾力正在为一幅作品的创作烦恼时,突然失去灵感,完全无法使用蓝绿两色。她也接受了音乐治疗,取得了很大疗效,蓝绿两色又回到了她的画板上。后来她说,莫扎特乐曲的效果实在太惊人了,感觉自己要10年才能完成的心理治疗,仅仅在8个月内就完成了。她感叹:“莫扎特就像我的爷爷,在我被噩梦惊醒时,他会第一个过来安抚我。”

(译自美国《时代》,文章有改动)

【相关链接】莫扎特命运坎坷,但乐天的心情一丝一毫都没有受到损害,只凭着坚定的信仰,像殉道的使徒一般唱着温馨甘美的乐曲安慰自己,安慰别人。他从来不把艺术作为反抗的工具,作为受难的见证人,而只借来表现他的忍耐与天使般的温柔。他自己得不到抚慰,却永远在抚慰别人。

(摘自傅雷《独一无二的莫扎特》)
