解方程： ． 答案：解：移项，得 2x+4=x−2 ， 两边平方，得2x+4=4-4x+x2， 即x2-6x=0， x（x-6）=0， x=0或x-6=0， 解得：x1=0或x2=6， 经检验，x=6是原方程的解， 所以原方程的解是x=6．University is generally regarded as one of the most important times in a person’s life, yet the function of this institution continues to arouse debate. Many believe that arts subjects are  too easy, that practical skills are more useful and that a chosen subject for study should be clearly linked to a career. However, this view is far too simplistic. Arts subjects are very difficult. They can prepare students for any number of careers as well as allowing the student to take time to make a decision. The function of the modern university is to cater to different types of student.Arts subjects are not easy. For example, a degree in Literature is not an easy option. No question in a Literature class has a single, simple answer. Debate is conducted in a spirit of openness, texts are very closely analyzed and skills in close reading are developed. Literature is about language, our primary means of communication. Arts subjects require the same concentrated study as any other subject.Arts subjects can prepare students for any number of careers. A degree in an arts subject teaches skills in well organized debates and defence of a position through the provision of evidence. These are applicable to many types of career. Law, for example. The point is that an undergraduate degree in any Arts subject trains the student in analysis and structure. Therefore, Arts graduates can pursue any number of careers.Arts subjects allow the student to take time to choose a career. Love of the subject for its own sake may well be the initial motivation for the Arts undergraduate but because the subject they have chosen is not so clearly linked to a career they have time to reflect, making a decision only when they are absolutely certain. Students who pursue Arts subjects therefore have the leisure to make a carefully considered choice.In conclusion, it is clear that Arts subjects are not a waste of time. They are flexible when it comes to relating them to a career and they allow the student to discover an appropriate career path. Many industries now acknowledge that a degree in Literature can be just as valuable as any other subject, especially when it is evident that Arts graduates tend to think more creatively. Not all undergraduates have clearly defined goals and not all subjects can be simply matched to a career. Acknowledging this difference should be the main function of a modern university小题1: What does the author mainly argue in this article?   A．Universities should be aware of diversityB．Universities should focus on practical courses.C．Arts courses should be promoted.D．Arts subjects are inappropriate for work.小题2:What does the author imply about universities’ attitude to students?   A．They need to be more understanding of students’ needs.
