要有过渡和承接，使得文章进展地流畅，这些过渡不一定要是in addition, therefore，so之类的写雅思作文用的词。过渡的要自然。
结尾是给招生官留下最后印象的一部分。不要使用in "in conclusion, in summary, to conclude之类的总结词。建议大家写得稍微幽默一点，招生官每天读文章读的很累，好不容易把你文章看完了，如果能在最后让他幽默一笑，嘴角犯上一丝笑容的话，说不定就让他记忆深刻了。可以巧妙的和开头相呼应一下。
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 for a 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.
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.
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, diligence 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.
