　　To begin with, even in such areas as computer science, where it is estimated that much of what a student learns today will be obsolete in just five years, an advanced degree and the education it represents will continue to be of benefit. Unlike undergraduate education, which is divided into a number of small educational units every term, post-baccalaureate education is concentrated on deeper learning in fewer areas. Moreover, most graduate education requires extended, critical focus on complex issues or research projects. And even if the technical information relevant to completing a graduate-level project becomes outmoded, the learned critical methods and problem-solving approaches will not.

　　2. 使用不同的句型结构

　　Today’s education system places too much emphasis on students’ desires rather than their needs. Accordingly, students are searching for the easy way out, and educators are willingly conspiring with them. As opposed to this trend, I would argue that students should study what is presented to them rather than what is desired by them. Not only should educators determine the curriculum, but also they should strive to insure that each individual student truly gains from his/her education, rather than just breezes through it.
