In 1905 Einstein published five highly important essays in the history of science, thus revolutionizing physics.

美国梦对不同的人有着不同的含义。

但对许多人，尤其是对移民而言，它意味着改善自己生活的机会。

对于他们，美国梦的含义就是才能与勤劳能让你从小木屋走向白宫。

托尼·特里韦索诺并没有爬那么高，但他成功地使自己的梦想成真。

托尼·特里韦索诺的美国梦弗雷德里克·C·克罗弗德他来自意大利罗马以南某地的一个遍地是石头的农庄。

他什么时候以及怎么到美国的，我不清楚。

不过，有天晚上，我看到他站在我家车库后面的车道上。

他身高五英尺七、八左右，人很瘦。

“我割你的草坪，”他说。

他那结结巴巴的英语很难听懂。

我问他叫什么名字。

“托尼·特里韦索诺，”他回答说。

“我割你的草坪。

”我对托尼讲，本人雇不起园丁。

“我割你的草坪，”他又说道，随后便走开了。

我走进屋子，心里有点不快。

没错，眼下这大萧条的日子是不好过，可我怎么能把一个上门求助的人就这么打发走呢？等我第二天晚上下班回到家，草坪已修整过了，花园除了草，人行道也清扫过了。

我便问太太是怎么回事。

“有个人把割草机从车库里推出来就在院子里忙活起来，”她回答说。

“我还以为是你雇他来的。

”我就把前晚的事跟她说了。

我俩都觉得奇怪，他怎么没提出要工钱。

接下来的两天挺忙，我把托尼的事给忘了。

我们在尽力重整业务，要让一部分工人回厂里来。

但在星期五，回家略微早了些，我又在车库后面看到了托尼。

我对他干的活夸奖了几句。

“我割你的草坪，”他说。

我设法凑了一小笔微薄的周薪，就这样托尼每天轻扫院子，有什么零活，他都干了。

我太太说，但凡有重物要搬或有什么要修理的，他挺派得上用场。

夏去秋来，凉风阵阵。

“克罗先生，块下雪了，”有天晚上托尼跟我说。

“等冬天到了，你让我在厂里干扫雪的活。

”啊，对这种执着与期盼，你又能怎样呢？自然，托尼得到了厂里的那份活儿。

几个月过去了。

我让人事部门送上一份报告。

他们说托尼干得挺棒。

一天我在车库后面我们以前见面的地方看到了托尼。

“我想当学徒，”他说。
