d. (2,0,2,0)
(一样是课本CH6的图)
12.(6%) Please describe the method, steps, and results of Vocal Separation for
Music.
备注:
(1) 热腾腾的考题,虽然老师似乎没有说什麽限制(但是题目卷有收回),可是只有前人
遗爱,才有後人乘凉,故整理了一下po上来
(2) 题目是小精灵生出来的,不要问、很可怕,配分和题目内容我保证有 99.99% 相同。
然後今年很...的出了50%名词解释,真的有够xx,而且助教说会考的专题部分,通通变
成方法、步骤、结果,同学的爱心都白废了,整体上考试体验非常糟,希望未来不会再
这样了QQ
(3) 考前有组读书会+共笔,虽然不能说猜题准,但还是有不小帮助,至少有看过的话,
不会完全空白不知道要写什麽,专题的部分就有啥写啥,反正改题同学有说,只要有把
关键字写出来,基本都给过~
(4) 考完老师会站在外面赌人,希望给建议跟改进的部分,同学千万别客气,有什麽抱怨
尽量说,这样期末应该会比较好过一些,不过会调分,所以考烂应该也不用太担心XD
