Unit 4

Train

A train is a connected series of vehicles for rail transport that move along a track to transport cargo or passengers from one place to another. The track usually consists of two rails, but might also be a monorail or maglev guideway.

Propulsion for the train is provided by a separate locomotive. Most modern trains are powered by diesel locomotives, although historically (from the early 19th century to the mid-20th century) the steam locomotive was the dominant form of locomotive power.

There are various types of train designed for particular purposes. A train can consist of one or more locomotives and attached railroad cars.

A passenger train may consist of one or several locomotives, and one or more coaches. Passenger trains travel between stations, at which passengers may board and disembark. In most cases, passenger trains operate on a fixed schedule and have superior track occupancy rights over freight trains.

Oversight of a passenger train is the responsibility of the conductor. He or she is usually assisted by other crew members, such as service attendants or porters. During the heyday of North American passenger rail travel, long distance trains carried two conductors: the aforementioned train conductor, and a Pullman conductor, the latter being in charge of sleeping car personnel.

Some passenger trains, both long distance and short distanced, may use bi-level (double-decker) cars to carry more passengers per train. Car design and the general safety of passenger trains have dramatically evolved over time, making travel by rail remarkably safe.

Freight trains comprise wagons , though some parcel and mail trains are more like passenger trains. Much of the world's freight is transported by train, and in the United States the rail system is used more for transporting freight than passengers. Under the right circumstances, transporting freight by train is highly economic, and also more energy efficient than transporting freight by

road. Rail freight is most economic when freight is being carried in bulk and over long distances, but is less suited to short distances and small loads.

列车

列车是铁路运输中连接起来的一组车辆，它们在轨道上行驶，从一地向另一地运输旅客或货物。轨道通常由两根钢轨组成，但是也有单轨和磁悬浮轨道。

列车的动力由单独的机车提供。多数现代列车由内燃机车提供动力，尽管在历史上（从19世纪初到20世纪中期）蒸汽机车是机车动力的主要形式。

有各种各样用于特别目的的列车。列车可以由一台或几台机车以及机车牵引的车厢组成。

旅客列车由一台或几台机车，一节或几节车厢组成。旅客列车在车站之间行驶，旅客在车站上下车。多数情况下，旅客列车按照固定时刻表运行，比货运列车有优先占用线路的权利。

管理旅客列车是列车员的责任。他通常由其他乘务人员协助，例如餐车服务员、行李员。在北美铁路公司的全盛时期，长途旅客列车上有两名列车员。一名负责整个列车，另一名卧铺车列车员，负责管理卧铺车上的旅客。

一些旅客列车（长途列车或短途列车）使用双层客车以便运送更多的旅客。随着时间的推移，旅客列车的车辆设计和安全规范日趋完善，使得乘火车旅行非常安全。

货运列车由货车车厢组成，尽管一些行包列车和邮政列车更像旅客列车。全世界的货物的大部分是由列车运输的，在美国，铁路更多的用于运输货物而不是旅客。在正常情况下，用列车运输货物是非常经济的，比用公路运输货物更能有效的利用能源。当大量、长途运输货物时，铁路货运是最省钱的，而短途、少量运输货物时，铁路是不合适的。

We do, however, seem to be dedicated to the idea of buying our way to happiness. We shall all have made it to heaven when we possess enough. 当然用傻子、骗子这样的字眼来形容是不合美国的人的风俗习惯的，然后我们似乎确实沉溺于用金钱购买幸福的想法：只要有足够的钱，我们百年后就能上天堂。 3、And at the same time the forces of American commercialism are hugely dedicated to making us deliberately unhappy.

Unit 4 (Para. 1) In the last few centuries, marriage has been connected to romantic love.This kind of package deal is not easy to maintain and indeed many people fail while trying to do so. Nevertheless, most people still pursue this deal. This is another type of paradox associated with marriage. 在过去的几个世纪里，婚姻总是和浪漫的爱情联系起来。这一揽子交易可不容易维护，的确，很多人在试图将婚姻和浪漫的爱情结合起来时失败了。不过，许多人仍然追求婚姻。这是和婚姻相关的另一种自相矛盾的情况。 (Para. 2)Some of the main difficulties of this package deal are the following: (a) in modern society, marriage is no longer unique in fulfilling tasks such as raising children and enhancing one’s status and financial situation,(b) long-term romantic relationships are problematic in that they lack significant changes, which are so meaningful to emotions in general and love in particular, and (c) the greater flexibility of romantic boundaries in modern society make it harder to maintain strict emotional connections and constraints, such as those recommended in marriage. 要实现这一揽子交易，有如下几点主要的困难：1. 在现代社会，婚姻已不是实现像抚养孩子，加强个人地位，及改善经济状况等任务的惟一形式。2. 长期的浪漫关系的问题在于他们缺乏重大变化，而变化对于普遍意义的情感特别是爱情具有重要意义。3.浪漫的界线在现代社会中更加灵活，这就使得那些在婚姻关系中建议的严格的情感联系和限制难以维持。 (Para. 3a) In modern society, most of the penalties for dissolving a marriage have been removed and many of the incentives that marriage offers can be obtained in other social frameworks. 现代社会中，大多数由于结束婚姻关系所受的惩罚已被取消，而婚姻关系提供的许多奖励也能通过其他社会结构获得。 The choice of staying within a marriage depends, therefore, more on the issue of love than on those traditionally unique advantages of marriage, such as raising children and enhancing one’s status and financial situation. 因此，选择继续留在婚姻中更多的是由于爱情而不是婚姻关系具有的那些传统的独特的优势，例如抚养孩子，加强个人地位，及改善经济状况。 (Para. 3b) If a person feels that her present marital relationship prevents her from experiencing genuine love (and from personal development and satisfaction), there is little incentive for her to stay in the marriage. The fact that most divorce cases now cite a lack of love as the reason for seeking to end the marriage indicates the greater importance that love has in contemporary marriages. 如果一个人觉得她目前的婚姻不能使她体验真挚的爱情，以及她的个人发展和内心满足，她就不太有维持婚姻关系的动机了。许多离婚案件现在会用缺少爱情作

新视野大学英语第一册Unit 1课文翻译

新视野大学英语第一册Unit 1课文翻译学习外语是我一生中最艰苦也是最有意义的经历之一。虽然时常遭遇挫折，但却非常有价值。我学外语的经历始于初中的第一堂英语课。老师很慈祥耐心，时常表扬学生。由于这种积极的教学方法，我踊跃回答各种问题，从不怕答错。两年中，我的成绩一直名列前茅。到了高中后，我渴望继续学习英语。然而，高中时的经历与以前大不相同。以前，老师对所有的学生都很耐心，而新老师则总是惩罚答错的学生。每当有谁回答错了，她就会用长教鞭指着我们，上下挥舞大喊：“错！错！错！” 没有多久，我便不再渴望回答问题了。我不仅失去了回答问题的乐趣，而且根本就不想再用英语说半个字。好在这种情况没持续多久。到了大学，我了解到所有学生必须上英语课。与高中老师不同，大学英语老师非常耐心和蔼，而且从来不带教鞭！不过情况却远不尽如人意。由于班大，每堂课能轮到我回答的问题寥寥无几。上了几周课后，我还发现许多同学的英语说得比我要好得多。我开始产生一种畏惧感。虽然原因与高中时不同，但我却又一次不敢开口了。看来我的英语水平要永远停步不前了。直到几年后我有机会参加远程英语课程，情况才有所改善。这种课程的媒介是一台电脑、一条电话线和一个调制解调器。我很快配齐了必要的设备并跟一个朋友学会了电脑操作技术，于是我每周用5到7天在网上的虚拟课堂里学习英语。网上学习并不比普通的课堂学习容易。它需要花许多的时间，需要学习者专心自律，以跟上课程进度。我尽力达到课程的最低要求，并按时完成作业。我随时随地都在学习。不管去哪里，我都随身携带一本袖珍字典和笔记本，笔记本上记着我遇到的生词。我学习中出过许多错，有时是令人尴尬的错误。有时我会因挫折而哭泣，有时甚至想放弃。但我从未因别的同学英语说得比我快而感到畏惧，因为在电脑屏幕上作出回答之前，我可以根据自己的需要花时间去琢磨自己的想法。突然有一天我发现自己什么都懂了，更重要的是，我说起英语来灵活自如。尽管我还是常常出错，还有很多东西要学，但我已尝到了刻苦学习的甜头。学习外语对我来说是非常艰辛的经历，但它又无比珍贵。它不仅使我懂得了艰苦努力的意义，而且让我了解了不同的文化，让我以一种全新的思维去看待事物。学习一门外语最令人兴奋的收获是我能与更多的人交流。与人交谈是我最喜欢的一项活动，新的语言使我能与陌生人交往，参与他们的谈话，并建立新的难以忘怀的友谊。由于我已能说英语，别人讲英语时我不再茫然不解了。我能够参与其中，并结交朋友。

Unit4 课文翻译及课后练习答案

Unit4 无子女家庭：违背十万年来的繁衍规律课文翻译：二十好几的凯茜、韦恩夫妇结婚已有五年之久，没有孩子。上次凯茜娘家有人问：“你们打算什么时候要孩子，组成一个家庭呢?”她答道：“我们已经是个家庭啦!” 凯茜与韦恩属于决定不要孩子的年轻已婚夫妇群体，其人数正在日益增长。最近一项调查显示在过去的五年中，年龄在25至29岁之间妇女不愿生养的百分比几乎翻了一番，在18至24岁的已婚妇女中几乎增至三倍。在这个似乎大胆反抗生物性和社会性的决定后面隐藏着什么原因呢? 或许最能公开坦陈心曲的无子女夫妇是《婴儿陷阱》一书的作者：埃伦，派克，其夫威廉，一位广告总经理兼全国不生养夫妇协会主席。派克夫妇认为他们和协会均无意反对生儿育女，不过是反对不管人们是否愿意和需要孩子就迫使人们传宗接代的社会压力。 “这是一种生活方式的选择，”埃伦说，“我们选择自由和自愿，清净和闲暇。这也是一个朝哪个方向付出努力的问题——在你自己的小家庭之内或在一个大的社团之中。这一代人面临有关地球生命延续的严重问题以及生命质量的问题。我们的孙辈也许将购票去观赏最后一批红杉或排队去获取氧气配给。有人抱怨在回到有五个孩子的家途中被交通堵塞困住好几个小时，但是他们不能将孩子与交通堵塞联系起来。在一个受到人口过剩一系列后果威胁的世界上，我们正在参与一项事业使膝下无子的生活模式为社会所接受并受世人尊重。太多的孩子作为一种文化强制的后果而呱呱坠地，离婚和虐待儿童的相关统计充分揭露了这一结果。” 埃伦的丈夫补充说：“每位朋友、亲戚、同事不停地给你施加压力，劝你要孩子，说什么‘发现你生活中失去的东西’。好多好多人很晚才发现，所谓他们失去的东西其实是他们完全不适合做的事情。” 埃伦还说：“从抱第一个洋娃娃开始，大到欣赏电视肥皂剧，成年后参加鸡尾酒会，无形之中，总有一种压力要你为人父母。但是让我们来看看养育失败的比率吧，或许天下父母应该视为像当医生一样的专门职业。有些人擅长此道，他们应当生养孩子；有些人一窍不通，他们应该认为他们还有其他的选择。” 专业观察家同意这一看法：很多人生养孩子没有正当的理由，有时候则完全没有理由。男人常常稀里糊涂就当上了父亲，根本就没有作出审慎的选择；对许多妇女来说，怀孕能够成为一种方式来逃避不可解决的冲突，譬如，迅速获得名分，或改进自己的不良形象，以及满足童年时代未曾得到的关注和关爱的需要。我与许多人类行为领域的专家交谈，探讨为什么那么多年轻夫妇决定不要孩子，他们的看法也是众说纷纭。一位家庭治疗专家把不要孩子的决定描写为“对当今世界形势基本的本能反应”，暗示像动物群居本能那样的东西正在起作用，来应对人口过剩、城市拥挤、环境污染与核战争危险。群居本能促使妇女感到繁殖人口有违心愿，并指引她们去寻找在家庭生活之外实现自我价值的新方式。不止一位精神病医生暗示，凡是不愿生育的人有都自恋癖——觉得自己心甘情愿迫不得已，为照顾别人与受人照顾这个互相对立的内心冲突自圆其说。有位精神病医生说：“这些人不能容忍照顾孩子的想法，他们没有多余的爱分享给孩子，”并补充道，“你们这是对亘古以来人类繁衍生生不息的离经叛道。”他的另一位同事插话说：“情有可原嘛，我们谁不想为我们的欠缺找理由? 且不论他

JOHN SNOW DEFEATS “KING CHOLERA John Snow was a famous doctor in London—so expert, indeed, that he attended Queen Victoria as her personal physician. But he became inspired when he thought about helping ordinary people exposed to cholera. This was the deadly disease of its day. Neither its cause nor its cure was understood. So many thousands of terrified people died every time there was an outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never be controlled until its cause was found. 约翰·斯洛是伦敦一位著名的医生——他的确医术精湛，因而成为照料维多利亚女王的私人医生。但他一想到要帮助那些得了霍乱的普通百姓时，他就感到很振奋。霍乱在当时是最致命的疾病，人们既不知道它的病源，也不了解它的治疗方法。每次霍乱暴发时，就有大批惊恐的老百姓死去。约翰·斯洛想面对这个挑战，解决这个问题。他知道，在找到病源之前，霍乱疫情是无法控制的。 He became interested in two theories that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person died. 斯洛对霍乱致人死地的两种推测都很感兴趣。一种看法是霍乱病毒在空气中繁殖着，像一股危险的气体到处漂浮，直到找到病毒的受害者为止。第二种看法是人们在吃饭的时候把这种病毒引入体内的。病从胃里发作而迅速殃及全身，患者就会很快地死去。 John Snow suspected that the second theory was correct but he needed evidence. So when another outbreak hit London in 1845, he was ready to begin his enquiry. As the disease spread quickly through poor neighborhoods, he began to gather information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why. 斯洛推测第二种说法是正确的，但他需要证据。因此，在1854 年伦敦再次暴发霍乱的时候，约翰·斯洛着手准备对此进行调研。当霍乱在贫民区迅速蔓延的时候，约翰·斯洛就开始收集资料。他发现特别在两条街道上霍乱流行的很严重，在10 天之内就死去了500 多人。他决心要查明原因。 First he marked on a map the exact places where all the dead people had lived. This gave him a valuable clue about the cause of the disease. Many of the deaths were near the water pump in Broad Street (especially numbers 16,37, 38 and 40) . He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame. 首先，他在一张地图上标明了所有死者住过的地方。这提供了一条说明霍乱起因的很有价值的线索。许多死者是住在宽街的水泵附近（特别是这条街上16、37、38、40 号）。他发现有些住宅（如宽街上20 号和21 号以及剑桥街上的8 号和9 号）却无人死亡。他以前没预料到这种情况，所有他决定深入调查。他发现，这些人都在剑桥街7 号的酒馆里打工，而酒馆为他们免费提供啤酒喝，因此他们没有喝从宽街水泵抽上来的水。看来水是罪魁祸首。Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used. Soon

博士英语课文翻译Unit4

Unit4 1.The crisis of global poverty has, at long last, been accorded a high priority on the international agenda. This propitious development has sparked a flurry of discussion and research concerning the means for eradicating this debilitating condition from human life. Yet as renewed pledges for action pour in from governments, as long-held theories and conventional approaches fail to quell long-held prejudices, conflicts, and exploitation, a feeling of rudderlessness looms over the global enterprise of poverty eradication. At the same time, a palpable optimism emerges from the attention and momentum generated by the search for solutions to this worldwide challenge. 2.The mechanisms of poverty eradication have long been defined in primarily material terms. Indeed, the central pillar of the international community’s poverty alleviation efforts has been the transfer of financial resources. Approximately $2.3 trillion have been spent on foreign aid over the last five decades.[1] Tragically, the aid, far from ushering in greater self-sufficiency, has often had a detrimental effect on recipient communities: increased dependency on foreign assistance, subservience to externally dictated priorities, misappropriation of funds and decreased pressure for governance reform. In a resolute push for change, the United Nations has sought to expand the mechanisms for assistance and to galvanize support for poverty alleviation through its Millennium Development Goals.[2] 消除贫困的机制，很久以来主要是用物质的术语界定的。事实上，国际社会努力缓解贫困的主要手段是调配资金。在刚刚过去的五十年里，大约2.3万亿美元花在了外援上1。可悲的是，这些援助不但未能帮助受援群体增强自立的能力，反而常常带给受援群体负面影响——增加了他们对外援的依赖、总是屈从于来自外部的指示、挪用资金、减低了政府自身改革的动力。为了坚决推进变革，联合国通过其制定的《千年发展目标》寻求扩展援助的机制，加大对扶贫的支持力度。 3.It is now increasingly acknowledged that such conditions as the marginalization of girls and women,[3] poor governance,[4] ethnic and religious antipathy,[5] environmental degradation[6] and unemployment[7] constitute formidable obstacles to the progress and development of communities. These evidence a deeper crisis—one rooted in the values and attitudes that shape relationships at all levels of society. Viewed from this perspective, poverty can be described as the absence of those ethical, social and material resources needed to develop the moral, intellectual and social capacities of individuals, communities and institutions. Moral reasoning, group decision-making and freedom from racism, for example, are all essential tools for poverty alleviation. Such capacities must shape individual thinking as well as institutional arrangements and policy-making. To be clear, the goal at hand is not only to remove the ills of poverty but to engage the masses of humanity in the construction of a just global order. 4.Individuals and institutions must work in tandem to take up this task. One of the goals of poverty alleviation, then, centers on the individual: he must be helped to reclaim his dignity and sense of self-worth, must be encouraged to gain confidence to improve his condition and strive to realize his potential. Beyond the achievement of personal well-being, he must be nurtured to become a source of social good—of peace, happiness and advantage to those around him. It is at the level of service to others that our humanity achieves its highest expression. The second goal centers on institutions: at every level of society, they must serve as channels through which the talents and energies of individuals can be harnessed in service to humanity. Resources that help to develop this individual and institutional capacity represent a true source of wealth to the community. 5.Much like the physical principles that govern the material world, the social world, too, is governed by moral principles, which underlie the functioning of an ordered society. Principles such as gender equality,[8] trustworthiness,[9] access to education, human rights and freedom of religion,[10] for example, tend to correlate positively with measures of socioeconomic well-being and stability. The interrelatedness of challenges stemming from poverty calls for the articulation of principles capable of guiding analysis, decision-making and the
