备注：
(1) 热腾腾的考题，虽然老师似乎没有说什么限制（但是题目卷有收回），可是只有前人
遗爱，才有后人乘凉，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。
然后今年很...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么，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，有什么抱怨
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
