2. 学习课程：

　　80. "All students should be required to take courses in the sciences, even if they have no interest in science."

　　90. "College students should be encouraged to pursue subjects that interest them rather than seek programs that promise entry into the job market."

　　94. "Universities should require every student to take a variety of courses outside the student&aposs field of study because acquiring knowledge of various academic disciplines is the best way to become truly educated."

　　In so far as the take the courses outside the student’s fields of study may expand him a wide spectrum of vision, I fundamentally agree with the speaker that the real “truly educated” should be based on the learning a wide scope of knowledge. However, close scrutiny reveals that overstate either the importance of the professional knowledge or the information outside will lead into jeopardize situation.

　　a) Since various disciplines were interrelated, the study of courses outside the students’ own field may benit the study of their own major.如：研究经济学的适当学习数学知识有利于对经济学的更深理解，如达芬奇Da Vinci即是科学家也是艺术家，他对人体解剖anatomy的深入了解，才使得他的油画十分优美，传神。

　　b) 首先，要解决一个问题，可能同时需要多方面知识，比如要编出一个很优秀的程序，仅仅懂得编程语言是不够的，还需要对软件工程，数学等方面知识的了解。比如，一个复杂的科研课题可能需要很多人共同合作完成，不但需要在专业知识上精通，如果具有管理学的知识可以更使工作更有效。其次，可以让学生发现她真正感兴趣的研究方向。比如德布罗意De Broglie开始是文学专业毕业的，后来接触了量子学才发现物理才是他的兴趣所在，后来提出了phase wave理论最后，广泛的学习各种知识能够拓宽视野

　　c) 过分强调学习其他学科的重要性可能会导致学生忽视专业的学习，毕竟社会需要对某方面有专长的人，这也是高校设置major的目的所在，浅尝辄止对个人和社会都无裨益;学习通信的整天忙于看文学，学习经济，哪里有时间去钻研通信方面的的知识，怎么合格的毕业?

　　d) 只有在自己专业上有很深的理解，才能有所成就。对一些理论的理解，不是肤浅的了解就能得到的，需要长时间案的积累。比如Roentgen伦琴就是在自己的专业上辛勤奋斗了许多年才发现了X-ray
