原文地址：http://www.surf.caltech.edu/students/personal_statementl.html

The personal statement is a significant part of your application. It provides other people with important information about you as a candidate for an undergraduate research position. It provides potential mentors and the selection committee with an impression of you as an individual.It is a way to measure your writing ability.（也是寫作能力的表現(xiàn)機會）

It states clearly your personal and professional goals and how participation in this program will help you achieve them.The personal statement can be used to determine your enthusiasm for participating in the program, your enthusiasm for the field, your maturity, your creativity, and your curiosity. （目標以及這個學習如何幫助你達到目標）

The people who will read your statement include potential mentors and evaluators who will recommend student selection.

There is no general recipe which, if followed to the letter, will guarantee a good personal statement. A good statement will anticipate and answer questions that prospective mentors or evaluators might ask about you. The questions below are not meant to be exhaustive or a check list. They are posed to stimulate your thinking about what you want to do and why you want to do it.下面這些問題將幫你構思ps寫作。

Your personal statement should clearly present how and why you became interested in a particular area of research and the steps you have taken to foster your interests. The people who read your personal statement should see your growth and interest over a period of time.

Some questions to consider when writing your personal statement:

1. Why are you applying? In what area of study do you want to specialize? What are your research interests?為何申請，什么領域，興趣何在。
2. What are your career goals (both short- and long-term)?長短期目標是什么
3. What makes you a special and unique applicant? What are you studying as an undergraduate? What special preparation did you receive?特點是什么，本科學過什么。
4. What about your extracurricular activities? Talk about your accomplishments and responsibilities. What are your strengths and weaknesses?
5. What are some of the problems you have had (personal, academic, research) and how did you resolve them? Make any explanations of problems positive and always articulate resolution of the problems. If you have any challenging or special experiences, describe them. These are the things that make you stand out and stay in the minds of the selection committee.你的一些困難，比如學習和研究以及個人問題，是如何克服的。
6. What do you know about the field? How did you get your information?
7. Do you have any work experiences that have contributed to your growth? Describe them.
8. What skills do you have that will help you succeed?什么技巧。
9. What specific areas of research conducted at Caltech (or one of the exchange universities) are you interested in? Are there particular faculty members whose work especially appeals to you?

The purpose of the personal statement that you are required to write and to submit is to describe yourself and your interests to the MURF admissions committee and to your prospective mentor.

Please describe your academic and career goals and discuss the ways in which your participation in the MURF program would help you achieve your goals. In what other ways have you fostered achievement of your goals (participation in other programs, other research experiences, etc.)?請寫出你的學術以及職業(yè)目標，并談論這個項目如何幫你

What are your research interests? (Be specific. We encourage you to review the faculty web sites to learn what research is carried out at Caltech and to read some articles about work that you find interesting.) What about this area of research interests you? What experiences or events piqued your interest? In what ways have you cultivated this interest?

感興趣的地方是什么，請具體。我們鼓勵你與研究領域的專家聯(lián)系，以及閱讀一些文章。
