托福口语题目：Some students believe that students should choose what courses they learn by themselves, while some students believe that professors should make decisions for students. Which opinion do you support? Give specific explanation in your response.一些学生认为学生应该自己选课，另一些认为应该由教授替学生选课。你支持哪种观点，给出理由。
Personally speaking, I prefer professors make decisions. The main reason is professors’ choices tend to be mature and informed. They are clear about what students should learn and master for certain subjects. Taking the economics for example, professors have been investigating in this field for decades, they know students should learn courses like mathematics, econometrics, statistics, finance and so on, so as to master the skills needed in economics. However, if choosing by students, they are likely to be in a puzzle or at a loss about which courses to learn, consequently they may not learn necessary knowledge and achieve desired results.
