    地域变异（regional variation）


    正确答案: 地理障碍如高山，海洋，空间的距离等是造成语言地域变异的主要原因，除此之外，对自己地方语的“忠诚”以及对语言变化的抵触情绪也是形成地域方言的原因。虽然语言的地域变异反映在发音、词汇和句法上，但是语言地域性变异的最显著的特征是地域口音（accent）。
    由于地域变体的存在给跨地区的交际造成障碍，语言规划（languageplanning）应运而生。语言规划是政府行为。政府常常选择某一特定的言语变体，对这种变体在语音、句法和词汇上进行语言标准化规划，并在社会中进行推广使用。

    问答题
    Practice 3　　What today’s global market economy teaches many of us who are involved in political life, is that even when they are inconvenient, the laws of economics, like the laws of physics, cannot be repealed for the convenience of governments. The economic principles for national success are as difficult to implement as they are easy to state. There is a paradox in all our countries at this moment. Just as a new global economy creates more to look forward to than ever before, it also brings more uncertainty and more change to worry about than ever before. That is why the challenge of crafting economic policy in your country as in mine is one of balance. A balance between moving toward necessary objectives and maintaining stability. A balance between responding to global realities and upholding domestic traditions. And a balance between the virtues of competition as the best known motivator and driver of success, and the importance of cohesion and cooperation as sources of strength for our societies. These balances will have to be struck and calibrated every year in every country in this new global economy. These measures are what one might call the intangible infrastructure of a modern market economy.

    正确答案： 【参考译文】
    我们许多从政者可以从当今全球市场经济中得到这样的启示,那就是经济学法则就像物理学法则一样,有一定的规律,即使当它们会引起诸多不便的时候,也不能为了政府的一时之便而朝令夕改。促进国家繁荣的经济原则,说起来容易,做起来难。此时此刻,我们所有国家都面临一个矛盾。新的全球经济创造的产物之多前所未有,让人期盼。同样,它带来的不确定性和变化也超越以往,令人担忧。和我国一样,贵国的经济政策也要量身定制,所面临的挑战是如何保持平衡:朝着必要的目标前进和保持稳定之间的平衡,顺应全球实际趋势和维护国内传统之间的平衡,以及竞争的裨益和团结、合作的重要性之间的平衡,竞争是最为人熟知的成功的动力,团结合作是我们社会力量的源泉。在这个新的全球经济中,各国每年都必须做一些适当的调整,以保持平衡。我们可以将这些措施称为一个现代市场经济的无形基础设施。
