另外，大家都喜欢介绍自己的学校，但是你的介绍要具体生动，不要总喜欢用什么prestigious和famous之类的话。有的同学这样写道：I went into a Univ. which won great reputation in telecommunication and IT field in China. 什么叫great reputation，有什么具体概念吗？大家不用停留在介绍学校方面，应该通过这种介绍迅速转入一点：你受到了high qualified的教育。

最大的问题，PS不要写成流水帐，每个段落要有核心句子。比如有的同学这样写道：In the first year, I was just a discreet learner, following the teacher’s step steadily. The second year, leader’s work in student government cost most of my time, so I tried to be more efficient. 这根本就不是PS，只能算回忆录。请注意：你要把最重要的信息放在段落的开头和结尾（Put the most important sentences at the beginning and end of the paragraph. When people skim passages, they look at the first and then the last sentence. Make a good first and last impression with substantive statements. Don't begin or end on fluff.）。

第四，除非特别要求，不要写成问答式的。有很多同学这样写：First, My old dream played a key role in my decision-making. 然后一大段介绍：Second, My solid academic background，然后下面再一大段，一直到第六个My Family background。还有的同学这样写：WHY IS MATHEMATICS? WHY ME？这绝对不是PS，千千万万要避免这种回答。如同华盛顿大学PS写作要求中提到的（http://www.flytowest.com/ps/usps/wash.htm）Avoid overly common phrases and nonspecific information.（避免用那些太平常的词组或者不具体的信息）。

第五，不要写为国家和社会主义做贡献之内的比较空泛的话。Besides traveling to Taiwan, realizing the importance of experiencing the real world, in the past three years, I have grasped every opportunity to travel far and observe the dynamic society and economy of China. 不要用同样的句式，比如有的同学总是喜欢用impress deeply这样的话，甚至一个段落中反复使用，要么就是不停地说intelligent。还有的就是句式雷同，Computer animation is my favorite and first choice，然后隔两句就写my primary and foremost interest lies in graphics and design。语言问题还有头重脚轻，比如Most computer majors look over this task because they consider it too easy; nonetheless, I do not agree. 实际上，语言问题还是小问题。你可以花100元钱请个认真负责的老外，找个学校的角落修改一下，一边communicate what you wish to say。实际上，关键的问题就是内容设置和结构布局。
