Hi,<br />I am a Ph.D. student, and this document is one field statement of my qualifying exam. I expect it to be clear and professional. Please indicate the confusing words or sentences so that I can revise and clarify accordingly. I use / to mark some words which I don't know which is best in the sentence, hope you can give me some suggestion on that too. Thanks so much!<br /><br />Best,<br />Sylvia
