PS分析

一篇好的PS首先要有一个精彩的开头。

但是大家往往会忽略这个部分。

本文主要叙述常见的几种写法，通过事例来告诉大家，这几种写法的优点与缺点。

（一）自我陈诉、开门见山、直入主题型例如：I am applying for admission to the Ph.D. program in Electrical and Computer Engineering, at the University of California, Berkeley. I present my research experience and study objectives in this statement of purpose.I would like to build on my solid education and experience as an engineer fora Ph. D. degree in computer science at a distinguished university. I wish in particular to be trained at an advanced level in software systems, database systems, applied-AI and knowledge-based systems. My ultimate goal is to become a professor teaching computer science at a Chinese university. I believe that advanced training in a quality graduate program will help me realize my goal.这种写法的优点是：开篇点明主题的目的性，让人一目了然。

这种写法的缺点是：在留学申请的过程中，太多人引用这样的写法，显得平淡，不能引起教授的兴趣。

（二）叙述故事，说理型1.叙述自己的家庭故事My father is a chartered accountant and my mother is a banker. During my days at Engineering College I used to go to my father's office and help him manage his portfolio of equities and other financial instruments. This was the time I learnt the first lesson of finance from my father i.e. risk and return are proportionate. In 1998 when I was in the second year the China stock market crashed. But fortunately, my father had a well-diversified portfolio because of which our returns were protected from the downside risk. This was when I learnt the second principle of finance from my father i.e. diversification reduces risk. While I understood these two principles intuitively, it produced in me a strong urge to learn and understand the complex theory behind the working of Finance. This, I believe, was a turning point in my career. I made up my mind to pursue a career in Finance and hence decided to do a Masters program in Business Administration.这种写法的优点：联系家庭，叙述自己。

给人感觉亲切。

这种写法的缺点：无法引起读者的强烈兴趣。

2. 叙述事件，引出自己的兴趣、观点。

As I was finishing college, my mother had both of her hips replaced with artificial ones because all of the cartilage in her hip joints had worn away and it was very painful for her to walk. I found it fascinating that engineers, orthopedic surgeons, and biologists had all worked together to design these artificial joints that completely transform. people's lives by giving them back pain-free mobility,and I knew at that moment that this was an area about which I wanted to learn more.In China these days, university graduates who have not been lucky enough to settle into their dream jobs often look to graduated studies as a way to kill the time that they cannot otherwise spend meaningfully. I am prepared to go against the social conventions by putting on hold a successful research career that promised to be even more successful. With eight years of productive and highly valued practical research behind me, I now would like to revert to a more intellectual life so that I can conduct more theoretical discourses.这种写法的优点：通过叙述事件来写，可以自然的连贯到自己的观点，兴趣，不会显的突兀。

这种写法的缺点：并不能引起读者强烈的兴趣。

（三）引用谚语、名言等。

When asked how to manage to mask remarkable statues, the French sculptor Auguste Rodin answered, “I choose a block of marble and chop off whatever I don't need.（法国雕塑家罗丹说：“给我一块大理石，把多余的去掉。

”）” For me, life is just a block of marble---whether the marble can be turned into a remarkable statue depends on your natural talents, diligenc e and a sense of duty. During over four years’ my college life, I have been dreaming of being a perfect female researcher so that I can enhance more young girls’ confidence in scientific research and encourage them to promote the development of science as men do.For Knowledge Itself Is Power.This is one of my favorite precepts and at this point in my life when I am about to complete my graduation and my future spreads in front of me like a dream, this adage has never influenced my life more than this before.这种写法的优点：引用谚语、名言来引出自己的观点，可以显示出作者有很强的文化底蕴。

这种写法的缺点：没有办法表现突出的个人特色。

（四）对该学科的认识感受型For the past three years, my undergraduate education has exposed me to the various sub-fields of Computer Science (CS). However, our syllabus has focused mainly on "traditional" CS topics, such as Operating systems and single-CPU systems. We have had barely a glimpse of the newer technologies that are likely to change the way computing is done in not-so-distant future. The desire to examine such subjects in greater detail is what has prompted me to opt for graduate study.Due to the comprehensiveness of China’s“reform. and open”policies, economics plays an increasingly important role in the development of its global position. As a senior at Beijing University majoring in Economics, I feel that my field is fundamental to the progress of my country. Yet, at the same time, I realize onlytoo well that what I have learned as an undergraduate is far from enough. Therefore, it is my desire to pursue a graduate degree I Economics at your university. If accepted, my intended concentration would be Economic Development and Public Economics这种写法的优点：可以显示出作者在该领域的认识，突出其兴趣。
