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。

新21世纪大学英语综合教程4 Unit1译文 Harsh Reality of the American Dream 美国梦的严酷现实
美国梦的严酷现实汉弗莱·霍克斯利这是西雅图海边阳光明媚、赤日炎炎的一天，穿越海湾能一眼望见远处的岛屿，其自然美景没有受到任何破坏。
人们躺在一片草坪上看书或和恋人相依，一阵充满活力的无伴奏的歌声从草坪的另一端传了过来。
原来是一家咖啡馆外面有4位男子正在唱着一首关于丘比特的情歌，每个人都有着不同的音域。
围了几圈的人群正摇摆着身体合着节奏拍手。
这家咖啡馆的星巴克徽标让我觉得有一点过时，直到有人提到这是世界上第一家开张的星巴克时我才恍然大悟。
我是因为最近的一次调查来到西雅图的。
这项调查是由位于伦敦的经济运转情况中心发起的，旨在了解在世界不同的地方发财致富究竟有多么容易或多么困难——如果不是发财致富，至少也是摆脱贫困。
“如果你生在美国的一个穷人家庭，”其中的一位作者说，“那么比起在欧洲、北欧国家，你更有可能终身贫困，就连在加拿大，一个你觉得和美国差不多的国家，那里的情况也要比美国好。
”机会这项研究连同伊拉克战争以来愈来愈普遍的反美情绪，让我想到了一个有关美国梦——认为在美国任何事情都有可能实现的想法——的问题。
我之所以选择西雅图不仅仅是因为星巴克诞生在那里，还因为微软、亚马逊图书以及波音飞机都来自这座小城市。
如果你愿意将它们称作梦想的话，那么这些小梦想现在已经变成了全球的大品牌。
“天气真不错，是吗？”我转过身来，看到一张布满皱纹、略显疲惫的男人的脸，我称呼他“戴夫”。
“你会得到你想要的吗？”我们几天前见过面，当时他正在一家帮助穷人和无家可归者的慈善机构里吃早饭，我曾问他是否相信美国梦。
“美国梦，”戴夫吃着松饼，用餐巾纸擦了擦嘴说道，“这个嘛，它时来时去。
它还会再来的。
”成功者和失败者在一家天花板很低的餐厅里，有一百来个男人沿着搁板桌并排而坐。
他们5点就开始排队登记了，因为说不定会有工作。
然后他们吃饭，而保安则在一边监视他们，以防有什么麻烦发生。
在欧洲或仅仅是边界那一边的加拿大，人们更有可能获得社会保障。

Model PaperCan Man Triumph over Nature?When people talk of man triumphing over nature, many things come to mind. One thinks of successes in medicine in the fight against disease, such as the invention of antibiotics and the promise held out by advances in biogenetic engineering. On a broader scale, one thinks of man's success in harnessing new forms of energy from steam power through oil to nuclear power.Yet, nature has often hit back in unexpected ways to these attempts to tame it. New forms ofAppendix I- 98 -disease that are resistant to antibiotics are constantly developing. Burning fossil fuels has led to fears of global warming; while nuclear power has produced dangerous waste that will remain a hazard for generations to come.However, perhaps to talk of man triumphing over nature is the wrong way to look at the matter. We need to find ways to work with nature rather than forever fighting against it.(154 w ords)。

冰雪卫士1812年，法国皇帝拿破仑带领他的大陆军进入俄国。
他已经做好了准备，对俄国人民保卫家乡进行残酷抵抗，他也准备好跨越俄国土地前去莫斯科的漫长征程。
然而，对于莫斯科那毁灭性的敌人------阴冷严寒刺骨的俄国冬日，他确没有做丝毫准备。
1914年，纳粹德国的领导者希特勒发起了对苏维埃俄国的进攻，紧接着俄国人民也奋博罗季诺起反抗了。
希特勒的军队是举世无双的。
他的战争武器已经打败了欧洲大多数反抗。
希特勒期待着一个短暂的战役，但是就像他之前的拿破仑一样，给他的却是一次惨痛的教训。
俄国的冬日再一次成为苏维埃士兵的救星。
拿破仑的战役1812年的春天，拿破仑在俄国的边境召集了一支60万人的军队。
士兵们都受过良好的训练，做事效率高，而且武器装备精良。
这支军队叫做大陆军。
拿破仑对于取得迅速胜利十分有信心，且预言说五个星期内征服俄国。
之后很快，拿破仑的军队越过涅曼河进入俄国。
拿破仑期望的迅速的决定性胜利并没有发生。
令他惊讶的是，俄军拒绝站起来反抗，取而代之的是向东方撤退，同时烧毁他们的庄稼和房屋。
大陆军紧随其后，但是向前的道路很快就被缓慢的物资供应阻碍了。
8月，法俄两军陷入斯摩棱斯克之战，双方各有一万士兵战死沙场。
然而俄军再次撤退至其领地。
拿破仑还没有取得决定性胜利。
他现在面临一个重大决定。
他是该继续追赶俄军呢？还是要留守斯摩棱斯克迎接即将来临的冬天呢？拿破仑决定赌一把，继续向448千米以外的莫斯科前进。
1812年9月7，法俄两军在距离莫斯科112千米以外的博罗季诺展开激烈战斗。
夜幕降临，3万法军和5万4千俄军要么战死沙场要重伤。
俄军再一次撤退至安全地带拿破仑对莫斯科有清楚的作战计划，但是对城市的占领却成了一场空胜利。
俄国人逃离了首都。
法军抵达后不久，一场猛烈的火灾摧毁的三分之二的城市。
拿破仑向亚历山大一世提出停战，但是俄国沙皇知道他是在等待时机：“我们应该让俄国的冬天帮我们打赢这场战争。
”拿破仑很快发现，在冬季的莫斯科，他不能为自己的军队提供粮食，衣物以及宿营地。

三、全文翻译Text A人在自然界亚历山大·斯伯金1人类生活在大自然的王国里。
他们时刻被大自然所包围并与之相互影响。
人类呼吸的空气、喝下的水和摄入的食物，无一不令人类时刻感知到大自然的影响。
我们与大自然血肉相连，离开大自然，我们将无法生存。
2人类不仅生活在大自然之中，同时也在改变着大自然。
人类把自然资源转变为各种文化，社会历史的财富。
人类降服并控制了电，迫使它为人类社会的利益服务。
人类不仅把各种各样的动植物转移到不同的气候环境，也改变了他生活环境的地貌和气候并使动植物因之而发生转变。
3随着社会的发展，人类对大自然的直接依赖越来越少，而间接的依赖却越来越多。
我们远古的祖先生活在大自然的威胁及破坏力的恐惧之中，他们常常连基本的生活物资都无法获取。
然而，尽管工具不甚完备，他们却能同心协力，顽强工作，并总是有所收获。
在与人类的相互作用中，大自然也发生了改变。
森林被破坏了，耕地面积增加了。
大自然及其威力被看成是和人类敌对的东西。
譬如，森林被认为是野性的和令人恐惧的，因此人类便想方设法使其面积缩小。
这一切都是打着“文明”的旗号进行的，所谓“文明”，就是人类在哪里建立家园，耕耘土地，哪里的森林就被砍伐。
4然而，随着岁月的流逝，人类越来越关注的是在何处得到和如何得到生产所需的不可替代的自然资源的问题。
科学与人类改变大自然的实践活动已经使人类意识到了工业在改变地球的进程中对地质产生的重大影响。
5目前，人与自然以及自然与社会整体之间过去存在的动态平衡，已呈现崩溃的迹象。
生物圈中所谓可替代资源的问题变得极为尖锐。
人类和社会的需求，即便是简单得像淡水一样的物质，也变得越来越难以满足。
清除工业废物的问题也变得日益复杂。
6现代技术的特征是生产和使用日益丰富的人工合成产品。
人们生产成千上万的人工合成材料。
人们越来越多地用尼龙和其他人造纤维把自己从头到脚地包裹起来，这些绚丽的织物显然对他们无益。
年轻人或许很少注意到这一点，他们更关注的是外表，而不是健康。
