>31 British Columbia
    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.

    英属哥伦比亚
    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。
>32 Botany
    Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights. It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things even for other plants. They have always been enormously important to the welfare of people not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognize literally hundreds of plants and know many properties of each. To them, botany, as such, has no name and is probably not even recognized as a special branch of "knowledge"at all.
    Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10, 000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild - and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.

    植物学
    植物学，即对植物的研究，在人类知识的历史中占据了特殊的地位。 这是人类几千年 来超越模糊的认知而真正有所了解的领域之一。 我们今天不可能知道新石器时代的祖先们 对植物到底了解多少，但我们在至今仍存在的前工业化社会观察到：人类对植物及其特性的 详细了解应该是非常古老的。 这是理所当然的。 植物是其他生物甚至其他植物食物金字塔 的基础。 它们对人们的生活至关重要，不仅在食物上，而且在衣物、武器、工具、染料、 药物、住所和许许多多其他的用途上。 至今仍生活在亚马逊河丛林中的部落确实能够辨识 几百种植物并知道每一种的许多特性。 对他们来说，植物学没有专门的名称，甚至可能根 本未被认为是一种专门知识。 不幸的是，工业化的程度越高，我们距直接与植物接触就越 远，我们的植物学知识的增加也就越微不足道。 然而每个人在不知不觉中拥有大量的植物 学知识，很少有人认不出玫瑰、苹果或兰花。 大约一万年前居住在中东的新时代的祖先们 发现某些草能被收获，它们的种子下一季耕种会收获更多时，人类就迈出了人和植物之间的 新关系第一大步。 谷子被发现后，农业的奇迹从此诞生：这就是可栽培的谷物。 从那时起， 人类越来越依赖少数可控制的作物生存，而不再是从众多的野生种类中这里获取一点，那里 获取一点。 这样在千万年中对于野生植物的经验和密切联系中积累起来的知识就开始消失 了。
