49、信，以此来纪念感恩节的真正意义。写三封感谢信亚历山大?黑利那是在二战期间的1943年，我是个年轻的美国海岸警卫队队员。我们的船，美国军舰军市一号已出海多日。多数船舱装着成千上万箱罐装或风干的食品。其余的船舱装着不少五百磅重的炸弹，都小心翼翼地放在有软垫的架子上。我们的目的地是南太平洋图拉吉岛上一个规模很大的基地。我是军市一号上的一个厨师，跟岸上的人样，那个感恩节的上午，我们忙着在准备一道以烤火鸡为主的传统菜肴。当厨师的都知道，要烹制一顿大餐，摆上桌，再刷洗、收拾干净，是件辛苦的事。不过，等到太阳快下山时，我们总算全都收拾停当了。我想先去后甲板透透气。我信步走去，一边深深呼吸着空气，一边慢慢地踱

50、着步，头上仍戴着那顶白色的厨师帽。我开始思索起感恩节这个节日来，想着清教徒前辈移民、印第安人、?野火鸡、南瓜、玉米棒等等。可我脑子里似乎还在搜索着别的什么一某种我能够赋予这一节日以个人意义的方式。大概过了半个小时左右我才意识到，问题的关键也许在于把Thanksgiving这个词前后颠倒一下那样广来至少文字好懂了：Givingthanks。表达谢意就如在祈祷时感谢上帝那样，我暗想。对啊，是这样，当然是这样。可我脑子里仍一直盘桓着这事。过了片刻，如同晨曦初现，一个更清晰的念头终于涌现脑际要感谢他人，那些赐我多恩惠，我根本无以回报的人们。令我深感不安的实际情形是，我向来对他们所做的一之泰然，认为是理

51、所应当。我一次也没想过要对他们中的任何一位真心诚意地说一句简单的谢谢。至少有七个人对我有过不同寻常、影响深远的帮助。令人万分难受的是，我意识到，他们中有一半已经谢世了因此他们永远也无法接受我的谢意了。我越想越感至懂愧。最后我想到了仍然健在的三位，几分钟后，我就回到了自己的舱房。我坐在摊着信纸的桌旁，回想着他们各自为我所做的一切，试图用真挚的文字表达我对他们的由衷的感激之情：父亲西蒙?A?黑利，阿肯色州派恩布拉大那所古老韵农业机械师范学院的教授；住在田纳西州小镇亨宁老家的外祖母辛西娅?帕尔默；以及我的初中校长，退休后住在亨宁以北6英里处的里普利的洛纽尔?纳尔逊牧师；我的信是这样开头的广出海在外度

52、过的这个感恩节，令我回想起您为我做了那么多事，但我却从来没有对您说过自己多么想感谢您”我简短回忆了他们每位为我所做的具体事例。例如，我父亲的最不同寻常之处在于，从我童年时代起，他就让我深深意识到要热爱书籍、热爱阅读。事实上，这一爱好渐渐变成一种家庭习惯，晚饭后大家围在餐桌旁互相考查近日所读的书以及新学的单词。我对书籍的热爱从未减弱，日后还引导我自己撰文著书。多少次，当我看到如今的孩子们如此沉迷于电子媒体时，我不由深感悲哀，他们很少，或者根本不了解书中所能发现的神奇世界。我跟纳尔逊牧师提及他如何每天清晨和集合在一起的学生做祷告，以此开始小镇初中的一天。我告诉他，我后来所做的任何有意义的事，都至少

53、部分地是受了他那些学校晨祷的影响。在给外祖母的信中，我谈到了她用了种种方式教我讲真话，教我与人分享，教我宽恕、体谅他人。我感谢她多年来让我吃她烧的美味菜肴，离开她后我从来没吃过那么可口的菜肴。最后，我感谢她，因为她在我的生命中撒下美妙的遐想。睡觉前，我这三封信都送进了船上的邮袋。我们抵达图拉吉岛后都寄了出去。我们卸了货，又装了其它物品，随后我们按熟悉的常规，再次出海。一天又一天，一星期又一星期，我个人的经历渐渐淡忘。我们在海上航行时，有时会与邮船会合，邮船会带给我们家信，当然，这是我们视为最紧要的事情。每当船上的喇叭响起广大伙听好!邮件点名!”200名左右的水手就会冲上甲板，围聚在那两个站在宝

54、贵的鼓鼓囊囊的灰色邮袋旁的水手周围。两人轮流取出一把把信件，大声念出收信水手的名字；叫到的人一边从人群中挤出来，一边应道：“来了，来了!”一次“邮件点名”带给了我外祖母、爸爸以及纳尔逊牧师的回信我读了信，既震惊又深感卑微。他们没有说他们原谅我以前不曾感谢他们，相反，他们却向我致谢，天哪；就因为我记得他们做的事，并认为他们做了不同寻常的事。身为大学教授的爸爸向来特别留意不使用任何过于感情化的文字，因此，当他信中写道，在教了许许多多的年轻人之后，他现在认为自己最优秀的学生当中也包括自己的儿子时，我知道他是多么地感动。纳尔逊牧师写道，他那平凡的老派校长的岁月随着学校里发生的如此迅猛的变化而告结束，他

55、也怀着自我怀疑的心态退了休。“说我做得不对的远远多于说我做得对的，”他写道，接着又说我的信给他带来了令人振奋的信心：自己的校长生涯还是有其价值的。一看到外祖母那熟悉的笔迹，我顿时回想起往日站在她的白色摇椅旁看她给亲戚写信的情景。外祖母一个字母一个字母地慢慢拼出一个词，接着再写下一个词，因此写满一页要花上几个小时。外祖母最近花费不少工夫对我表达了充满慈爱的谢意，读着老人家的信我禁不住流泪从前是她给我换尿布的呀!许多年后，我从海岸警卫队退役，试着靠写作为生，我一直不曾忘记那三封“感谢”信是如何使我认识到，大凡人都暗自期望着有更多的人对自己的努力表达谢意。现在，感恩节又将来临，我自问，对此文的读者，对我们的祖国，事实上也是对全世界，我有什么祝愿，因为，用一位善良而且又有智慧的朋友的话来说，“我们究其实都是十分相像的凡人，有着相似的需求。”当然，我首先祝愿大家记住这一简单的常识：实现世界和平，这对我们自身的存亡至关重要。此外我还有别的祝愿这一祝愿是如此强烈，我将这句话印在我所有的信笺底部：“发现并褒扬各种美好的事物。”课文B谢谢今天你要说的最重要的这两个字，能够改变你的生活，研究也证明如此。研究表明，有感恩意识的人会因此而过上更加充实
