071 它们只是朋友 They re just friends

Engineering classes at the university are tough,and struggling students sometimes go to extremes in order to pass. Grading exams one semester,I got to this question:"What is the relationship between kinetic and potential energy" One student,obviously stumped,decided to get clever and wrote,"As far as I know,they're just friends,but there could be something else going on there."

大学的工程课程难度很大,成绩差的学生为了要得个合格有时要走极端。有一个学期我在批考卷的时候,批到一道"动能和势能之间有什么关系?"的题目,一个显然发懵的学生自作聪明地答道:"就我所知,它们只是朋友,不过或许它们之间还有点什么事儿。"

extreme n. 极端,极度,极限 semester n. 学期
