【篇一】英属哥伦比亚

British Columbia is the third largest Canadian province, both in area and population. It is nearly 1.5 times as large as Texas, and extends 800 miles (1,280km) north from the United States border. It includes Canada’s entire west coast and the islands just off the coast.

Most of British Columbia is mountainous, with long rugged ranges running north and south. Even the coastal islands are the remains of a mountain range that existed thousands of years ago. During the last Ice Age, this range was scoured by glaciers until most of it was beneath the sea. Its peaks now show as islands scattered along the coast.

The southwestern coastal region has a humid mild marine climate. Sea winds that blow inland from the west are warmed by a current of warm water that flows through the Pacific Ocean. As a result, winter temperatures average above freezing and summers are mild. These warm western winds also carry moisture from the ocean.

Inland from the coast, the winds from the Pacific meet the mountain barriers of the coastal ranges and the Rocky Mountains. As they rise to cross the mountains, the winds are cooled, and their moisture begins to fall as rain. On some of the western slopes almost 200 inches (500cm) of rain fall each year.

More than half of British Columbia is heavily forested. On mountain slopes that receive plentiful rainfall, huge Douglas firs rise in towering columns. These forest giants often grow to be as much as 300 feet (90m) tall, with diameters up to 10 feet (3m). More lumber is produced from these trees than from any other kind of tree in North America. Hemlock, red cedar, and balsam fir are among the other trees found in British Columbia.

【篇二】译文

英属哥伦比亚是加拿大的第三大省，无论是面积还是人口都是如此。它几乎是德克萨斯的1.5倍，从美国边境一直向北延伸了800英里（1,280公里）。它包括了加拿大整个西海岸及附近岛屿。

大部分英属哥伦比亚多山峦。绵长而粗犷的山脉贯通南北。甚至那些沿海的岛屿都是那些存在于千万年前的山脉的遗迹。在上一个冰河时期，这些山脉被冰河冲刷侵蚀，直到大部分山脉被淹没在海中。它们的峰顶显现为沿着海岸散布的岛屿。

西南海岸地区有着潮湿温和的海洋性气候。从太平洋来的温暖的洋流使得从西吹过内陆的海风变得温暖。因此这儿冬天平均气温在零上而且夏天也不会酷热。这些温暖的西风同样也从海洋带来了湿气。

来自太平洋的、从海岸向内陆的风遇到海岸山脉和落基山脉这些山脉屏障。当气流升高跨越这些山脉时，风的温度就降低了，风中的水分形成降雨。在一些朝西山坡区域每年大约有200英寸（500厘米）的降水。

大部分英属哥伦比亚密布着森林。在有充足降水的斜坡，巨大的道格拉斯枞树高耸入云。这些森林巨人常常长到高达300英尺（90米），直径粗达10英尺（3米）。这些树产出了比北美其他任何树都多的木材。铁杉、红香椿、香脂冷杉枞都是发现于英属哥伦比亚的其它树种。

The Origin of Refrigerators

By the mid-nineteenth century, the term “icebox” had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War(1861-1865),as ice was used to refrigerate freight cars, it also came into household use. Even before 1880,half of the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.

Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

【篇四】译文

冰箱的由来

直到19世纪中期，"冰箱"这个名词才进入了美国语言，但冰仅仅只是开始影响美国普通市民的饮食。冰的买卖随着城市的发展而发展。冰被用在旅馆、酒馆、医院以及被一些有眼光的城市商人用于肉、鱼和黄油的保鲜。内战（1861-1865）之后，冰被用于冷藏货车，同时也进入了民用。甚至在1880年前，半数在纽约、费城和巴尔的摩销售的冰，三分之一在波士顿和芝加哥销售的冰进入家庭使用，因为一种新的家庭设备，冰箱，即现代冰箱的前身，被发明了。

制造一台有效率的冰箱不像我们想象的那么简单。19世纪早期，关于对冷藏科学至关重要的热物理知识是很浅陋的。认为的冰箱应该防止冰的融化这样一个普遍的观点显然是错误的，因为正是冰的融化起了制冷作用。早期为节省冰的努力，包括用毯子把冰包起来，使得冰不能发挥它的作用。直到近19世纪末，发明家们才成功地找到有效率的冰箱所需要的精确的隔热和循环的精确平衡。

但早在1803年，一位有发明天才的马里兰农场主，托马斯·莫尔，找到了正确方法。他拥有一个农场，离华盛顿约20英里，那里的乔治镇村庄是集市中心。当他用自己设计的冰箱运送黄油去市场时，他发现顾客们会走过装在竞争者桶里那些迅速融化的黄油而给他比市价更高的价格买他仍然新鲜坚硬，整齐地切成一磅一块的黄油。莫尔说他的冰箱的一个好处是使得农民们不必在夜里上路去市场以保持他们产品的低温。
