一、 作文
AA-new-8:
The following appeared in a memorandum from the marketing department of Reel magazine.
“In order to determine the cause of the recent decline in sales of our magazine, we sent a survey to customers who have cancelled their subscription during the last nine months. Results indicate that 80 percent of the 450 respondents feel that Reel contains too many ads. In order to retain current customers and win back customers who have cancelled their subscriptions, we should reduce the number of ads. This solution will not only improve customer satisfaction but also increase our revenue by boosting magazine sales.”
Discuss how well reasoned . . . etc

“The most effective way for a businessperson to maximize profits over a long period of time is to follow the highest standards of ethics.”
Discuss the extent to which you agree or disagree with the opinion stated above. Support your views with reasons and/or examples from your own experience, observations, or reading.
The speaker claims that following high ethical standards is the best way to maximize profits in the long run. However, this claim seems to be more of a normative statement than an empirical observation. The issue is more complex than the speaker suggests. In my observation, the two objectives at times coincide but at other times conflict.
In many ways behaving ethically can benefit a business. Ethical conduct will gain a company good reputation that earns repeated business. Treating suppliers, customers and others fairly is likely to result in their reciprocating. Finally, a company that treats its employees fairly and with respect will gain their loyalty which, in turn, usually translates into higher productivity.
On the other hand, taking the most ethical course of action may in many cases reduce profits, in the short run and beyond. Consider the details of a merger in which both firms hope to profit from a synergy (n.最佳协合作用,企业合并后的协力优势) gained thereby. If the details of the merger hinge on (v. 靠..转动, 以..为转移) the ethical conviction that as few employees as possible should lose their jobs, the key executives may lose sight of the fact that a leaner, less labor-intensive organization might be necessary for long-term survival. Thus, undue concern with ethics in this case would results in lower profits and perhaps ultimate business failure.
This merger scenario points out a larger argument that the speaker misses entirely-that profit maximization is per se the highest ethical objective in private business. Why? By maximizing profits, businesses bestow a variety of important benefits on their community and on society: they employ more people, stimulate the economy, and enhance healthy competition. In short, the profit motive is the key to ensuring that the members of a free market society survive and thrive. While this argument might ignore implications for the natural environment and for socioeconomic (of, relating to, or involving a combination of social and economic factors) justice, it is a compelling argument nonetheless.
Thus the choice to follow high ethical standards should not be made by thinking that ethical conduct is profitable. While in some cases a commitment to high ethical standards might benefit a company financially, in many cases it will not. In the final analysis, businesses might best be advised to view their attempts to maximize profits as highly ethical behavior.

说说从600－到650＋的感受。
首先非常感谢CD。CD是我们的家。是Jeremy2000让我知道这个论坛的，我非常感谢他。
我考了两次，两次的分数都不好，但我想很多同分数段的朋友们可能需要他人的经验和教训。我第一次是彻底错估了ETS的实力，把它当成“一踢死”了。虽然很辛苦地遍览了几乎所有可能找到的考试资料，包括LSAT，但仍惨败而归。懵懵然不知何因。
还好找到了CD，我觉得成绩的提升主要来自CD的帮助。依靠CD，我做了如下工作：一、不闭门造车，看牛人心经，向他们学习。二、研究OG，把每道RC，CR和SC的解释看清。三、临考前细看JJ，最好把JJ打印出来，写写画画。四、以CD上可以找到的一些接近实考情况的整套试题进行模考。这样在第二次考试中，终于提高了考试成绩而避免在原地踏步。遗憾的是，对OG的理解深度还是不够，没有考出更好成绩。
如果再考，我认为，还是把ETS当作“外星人E.T.”吧，不等闲视之，放弃题海战术，争取彻底把OG吃透。可以在原有基础上，进一步注意以下几个方面：一、心经不仅要看，更重要是按此执行。二、再研究OG，把每一道RC和CR的5个解释都看清，思考自己的理解与ETS的异同。三、把CD上讨论的OG题全部都看一遍，并将疑点记在OG书上。四、模考错在5、6个之内再碰ETS。
以上请XDJM指正。
祝大家取得更好成绩！
