间的一种让与取。每个人都要完成自己那部份工作。我每年重读三本书。我每年春天都要读的第一本书是海明威（EmeStHemingWay）的《流动的盛宴》。这是他对20年代的经典回忆录，于1964年出版。这本书的语•言几乎令人陶醉，一位年迈的作家回首一个雄心勃勃却又更简单的时代。另一个是AnnieDillard的《神圣的坚实》，她写于1975年的充满诗意的关于一切和虚无的随笔。第三本书是JUIioCOrUZar的《拯救黎明：诗选》。因为诗歌，也因为COrtdZar.虽然我倾向于购买很多书，但这三本书是作为礼物送给我的，这可能会增加我对它们的重视。但是我认为，尽管金钱确实是绝妙的和必要的，但是重新阅读作者的作品是读者可以支付的最有价值的货币。最好的书是随着时间的流逝而进一步开放的书。但是请记住，是您必须成长，阅读和重新阅读才能更好地了解您的朋友。C篇【1】研究表明，竞走和跑步在健身方而有很多共同的好处，然而，竞走降低受伤的可能性更大。不过，它也有自己的问题。【2】竞走运动员是有条件的运动员。夏季奥运会上最长的田径项目是50公里竞走，比马拉松长约5英里。但这项运动的规则要求竞走者在大部分摆动腿的过程中膝盖要保持笔直，一只脚要始终与地面接触。不过,马萨诸塞州塞勒姆州立大学(SalemStateUniVerSity)运动科学助理教授贾克琳•诺伯格(JaCIynNOrberg)说,正是这种奇怪的形式让竞走成为一项如此吸引人的活动。【3】她说，和跑步一样，竞走也需要体力。根据大多数计算，竞走者以每小时6英里的速度运动，每小时可以燃烧大约800卡路里，大约是步行燃烧的热量的两倍，尽管比跑步要少。跑步每小时大约可以燃烧1000或更多卡路里。[4]然而，诺本博士说，竞疋不会像跑步那样对身体造成那么大的冲击。根据她的研究，跑步者每一步着地的重量是自己体重的四倍，而不离开地而的竞疋者每一步着地的重量大约是自己体重的1.4倍。【5】因此，她说，一些与跑步有关的伤害，如跑步者的膝盖，在竞走者中并不常见。但这项运动奇怪的形式确实给脚踝和臀部带来了相当大的压力，所以有过此类伤病史的人在从事这项运动时可能要谨慎一些。她说，事实上，任何想尝试竞走的人可能应该首先咨询教练或有经验的竞上者，学习适当的技术。这需要一些练习。D篇人与植物的关系一直是科学研究的课题。最近的研究发现了积极的效果。例如，在俄亥俄州扬斯敦进行的一项研究发现，城市绿化较好的地区犯罪率较低。另一项研究显示，当员工的工作场所被室内植物装饰时，他们的工作效率提高了15%O麻省理工学院(MIT)的

地下水中有害化学物质的植物。麻省理工学院化学工程教授迈克尔•斯特拉诺(MiChaelStranO)解释说：“我们正在考虑如何设计植物，以取代我们日常使用的东四的功能。“【3】他最近的一个项目是用一些普通的蔬菜让植物发光。斯特拉诺的团队发现，他们可以在三个半小时内创造出微弱的光线。光是阅读所需量的千分之一，这只是一个开始。斯特拉诺说，这项技术有一天可以用来点亮房间，甚至把树木变成自动供电的路灯。[4]未来，该团队希望开发出一种可以一次性喷洒到植物叶子上的技术，使植物的寿命持续。工程师们还在尝试开发一种开关，当暴露在日光下时，它的光能会减弱。【5】照明约占美国总耗电量的7%O由于照明通常远离电源——例如从发电厂到偏远公路上路灯的距离——在传输过程中会损失大量能源。发光的植物可以缩短这段距离，从而帮助肖约能源。
