"In order to improve the quality of instruction at the college and university level, all faculty should be required to spend time working outside the academic world in professions relevant to the courses they teach."
Whether college faculty should also work outside academia, in professional work related to their academic fields, depends primarily on the specific academic area.
With respect to fields in which outside work is appropriate, I strongly agree with the statement; students and faculty all stand to gain in a variety of respects when a professor complements academic duties with real-world experience.
这一段要了解的一个词：stand to = begin to come to作者在首段就点明了"个别问题个别分析对待"，但是也不能忽视practical experience对academic world的重要作用。
As a threshold matter, the statement requires qualification in two respects.这一句可作为自己的开头句。First, in certain academic areas there is no profession to speak of outside academia. This is especially true in the humanities; after all, what work outside academia is there for professors of literature or philosophy? Secondly, the statement fails to consider that in certain other academic areas a professor's academic duties typically involve practical work of the sort that occurs outside academia. This is especially true in the fine and performing arts, where faculty actively engage in the craft by demonstrating techniques and styles for their students.
Aside from these two qualifications, I strongly agree that it is worthwhile for college faculty to work outside academia in professional positions related to their field. There are three dear benefits of doing so. First, in my experience as a student, faculty who are actively engaged in their fields come to class with fresh insights and a contagious excitement about the subject at hand. Moreover, they bring to their students practical, real-world examples of the principles and theories discussed in textbooks, thereby sparking interest, and even motivating some students to pursue the field as a career.
Secondly, by keeping abreast with the changing demands of work as a professional, professors can help students who are serious about pursuing a career in that field to make more informed career decisions. The professor with field experience is better able to impart useful, up-to-date information about what work in the field entails, and even about the current job market. After all, college career-planning staff are neither equipped nor sufficiently experienced to provide such specific advice to students.
A third benefit has to do with faculty research and publication in their areas of specialty.
Experience in the field can help a professor ferret out (=find out)cutting- edge and controversial issues——which might be appropriate subjects for research and publication. Moreover, practical experience can boost a professor's credibility as an expert in the field. For example, each year a certain sociology professor at my college combined teaching with undercover work investigating various cults. Not only did the students benefit from the many interesting stories this professor had to tell about his experiences, the professor's publications about cults catapulted him to international prominence as an expert on the subject, and justifiably so.
In sum, aside from certain academic areas in which outside work is either unavailable or unnecessary, students and faculty alike stand everything to gain when faculty enrich their careers by interspersing field work with academic work.
