GRE，全稱Graduate Record Examination，中文名稱為美國研究生入學(xué)考試，適用于除法律與商業(yè)外的各專業(yè)。由美國教育考試服務(wù)處(Educational Testing Service，簡稱ETS)主辦，GRE是美國、加拿大的大學(xué)各類研究生院（除管理類學(xué)院，法學(xué)院）要求申請者所必須具備的一個考試成績，也是教授對申請者是否授予獎學(xué)金所依據(jù)的最重要的標(biāo)準(zhǔn)。 另有，Generic Routing Encapsulation（通用路由封裝）也簡稱GRE。
In sum, because we devise machines in order that they may serve us, it is fair to
characterize machines as "tools of human minds." And insofar as humans have the unique
capacity for independent thought, subjective judgment, and emotional response, it also seems
fair to claim superiority over our machines. Besides, should we ever become so clever a
species as to devise machines that can truly think for themselves and look out for their own
well-being, then query whether these machines of the future would be "machines'' anymore.
Issue 71
"The most essential quality of an effective leader is the ability to remain consistently committed
to particular principles and objectives. Any leader who is quickly and easily influenced by shifts
in popular opinion will accomplish little."
Whether effective leadership requires that a leader consistently follow his or her principles and
objectives is a complex issue--one that is tied up in the problem of defining effective leadership
in the first place. In addressing the issue it is helpful to consider, in turn, three distinct forms of
leadership: business, political, and social-spiritual.
In the business realm, effective leadership is generally defined, at least in our corporate
culture, as that which achieves the goal of profit maximization for a firm's shareholders or other
owners. Many disagree, however, that profit is the appropriate measure of a business leader's
effectiveness. Some detractors claim, for example, that a truly effective business leader must
also fulfill additional duties--for example, to do no intentional harm to their customers or to the
society in which they operate. Other detractors go further--to impose on business leaders an
affirmative obligation to yield to popular will, by protecting consumers, preserving the natural
environment, promoting education, and otherwise taking steps to help alleviate society's
problems.
Whether our most effective business leaders are the ones who remain consistently
committed to maximizing profits or the ones who appease the general populace by
contributing to popular social causes depends, of course, on one's own definition of business
success. In my observation, as business leaders become subject to closer scrutiny by the
media and by social activists, business leaders will maximize profits in the long term only by
taking reasonable steps to minimize the social and environmental harm their businesses

cause. Thus the two definitions merge, and the statement at issue is ultimately correct.
In the political realm the issue is no less complex. Definitions of effective political leadership
are tied up in the means a leader uses to wield his or her power and to obtain that power in the
first place. Consider history's most infamous tyrants and despots--such as Genghis Khaan,
Stalin, Mao, and Hider. No historian would disagree that these individuals were remarkably
effective leaders, and that each one remained consistently committed to his tyrannical
objectives and Machiavellian principles. Ironically, it was stubborn commitment to objectives
that ultimately defeated all except Khan. Thus in the short term stubborn adherence to one's
objectives might serve a political leader's interest in preserving his or her power; yet in the long
term such behavior invariably results in that leader's downfall if the principles are not in
accord with those of the leader's would-be followers. 感謝您閱讀《GRE作文范文大全（33） 》一文，出國留學(xué)網(wǎng)(liuxue86.com)編輯部希望本文能幫助到您。
