四级写作常见话题及范文：大学生活学习

　　Most faculty at large universities advise students in their academic programs and direct graduate students in preparing their masters theses and doctoral dissertations. (A thesis or a dissertation is an extensive research paper usually required for the satisfactory completion of an advanced degree).

　　After they are hired by a college or university, faculty members receive a faculty rank as part of their appointment. Those who are beginning their teaching career and have little previous experience enter the profession as either instructors or assistant professors. The rank of assistant professor is slightly higher than that of instructor. After an assistant professor has acquired some teaching experience, conducted research, published articles or books, and served on institutional and departmental committees, he or she is usually promoted to associate professor. The highest rank of the faculty is full professor, sometimes simply called professor.

　　To save money and to be able to quickly respond to changing trends in education, colleges and universities increasingly employ large numbers of part-time teachers . Part-time faculty usually receive lower salaries than faculty with full-time positions, forcing many to teach at several colleges or universities in order to earn an adequate income. Critics believe that reliance on part-time faculty and teaching assistants decreases the quality of instruction.
