每一次在找翻译练习材料的时候，我都感觉比较艰难。总觉得找到的材料不令人满意。说实话，截止目前为止，还没有找到一篇特别让我满意的练习文章。要找到尽可能的和考研的真题重合的文章是比较困难的。

但是，为了提供给大家较高质量的练习，为了让大家花少量的时间达到一种比较理想的复习效果，我尽量在划线的句子上下些功夫。让划线的句子尽量去贴近考试中的句子难度，但是尽管如此，也不是十分令人满意。从找一篇文章，到看完，自己大概翻译完这篇文章，到给句子划线，其中的过程是一个不断追求"完美"的过程；其中的心路历程，是非亲自体验而不能言状的。

总的来说，既然给出了句子来了，至少是这一段时间（可能是选题的一个上午，一整天，有时候甚至持续一个星期）找到的比较满意的练习材料。

大家动手吧，老规矩,做完之后，我会抽部分来给大家一些学习的建议。

The economic system
of any nation is the mechanism which brings together natural
resources, the labor supply, technology, and the necessary
entrepreneurial and managerial talents. Anticipating and then
meeting human needs through production and distribution of goods
and services is the end purpose of every economic system.
57）While the type of economic system used by a nation
is the result of political decision, it is also in even larger part
the result of a historical experience, which over time becomes a
national culture.


The first ingredient of the system is the natural resource from
which goods are produced. 58）America has been blessed by being a land rich in
mineral resources and fertile farm soil, together with a moderate
climate.


Second, the amount of available labor helps determine the health of
an economy. 59）Generally the United States has been fortunate in
having enough people to provide the labor necessary for a
constantly expanding economy. Until 1924 most of these workers were white
immigrants (or their immediate descendents) who came to
America from Europe. 60）When too many laborers arrived from Europe to be
absorbed by the East-coast economy, they could move on to farmland
in the interior. It is true that at times the country has
experienced periods of acute unemployment as well as labor
shortage, but on the whole immigrants came when work was plentiful
and economy grew fast enough to absorb them, providing they were
willing to work productively at slightly less than the wage rates
paid the acculturated workers. They were willing, and they
prospered, earning far more than they would have in their native
land. As a result, the economy of the nation also
prospered.


A third factor is the quality of available labor. In assessing the
success of an economy one must ask how hard the people are willing
to work and how skilled they are. The frontier demanded hard work,
and the Protestant religious ethic supported that demand. Further,
the strong emphasis placed on education, including technical and
vocational education, also contributed to America's economic success. 61）Likewise, the willingness to experiment, to change
and to invest in technology was significant in a land that had
prided itself on being a new experiment in
freedom.
