小火车头

His own children had grown up, and married, and four times he had seen before him on the tracks the ghastly dot of tragedy converging like a cannon ball to its eclipse of horror at the boiler head—a light spring wagon filled with children, with its clustered row of small stunned faces; a cheap automobile stalled up the tracks, set with the wooden figures of people paralyzed with fear; a battered hobo walking by the rail, too deaf and old to hear the whistle's warning; and a form flung pas his window with a scream—all this he had seen and known.

他曾4万次在他面前的铁轨上看到了可怕的悲剧所凝聚的小点，象颗炮弹似的射向火车头前的恐怖的阴影－－－1辆满载小孩子的轻便马车和密密一排惊惶失措的小脸，一辆廉价汽车停在铁轨上，里面坐着吓得目瞪口呆状若木鸡的人们，一个带着惊呼的人影掠过他的窗口－－－所有这些，司机都历历在目，记忆犹新。

当初她有一个小孩缠着她的裙子，现在这孩子已长成大姑娘，也每天和她母亲一起出来挥手致意。司机多年操劳，已经白发苍苍，渐渐变老了。他驾驶长长的列车栽着旅客横贯大地已上万次。他自己的子女都已长大了，结婚了。他曾4万次在他面前的铁轨上看到了可怕的悲剧所凝聚的小点，象颗炮弹似的射向火车头前的恐怖的阴影－－－1辆满载小孩子的轻便马车和密密一排惊惶失措的小脸，一辆廉价汽车停在铁轨上，里面坐着吓得目瞪口呆状若木鸡的人们，一个带着惊呼的人影掠过他的窗口－－－所有这些，司机都历历在目，记忆犹新。

Since her tenth birthday, Naida had lived in a mental hospital, in the ward where they put people who were strange in shape and ways—where old frail women were tucked under thin frayed bedspreads, waiting for the time when their jaws would drop suddenly in the night; where curious bland children with slit eyes and lips bubbling with saliva played with rag toys or a red wooden engine in a yard that was hidden from the outside world.

从十岁起，奈达就住在了一个精神病院，那些长相怪异，处世疯癫的人们被关在那儿的病房里。在那里，年老体弱的妇人蜷缩在磨损得不成样子的床单下，绝望地等待着在某天晚上咽下最后一口气。在那里，好奇且百无聊赖的孩子们眯缝着惺松的眼，嘴角挂着哈拉子，在他们与世隔绝的小天地－院子里－摆弄着他们的破玩具，或者是，那个红色的木制火车头。
