Do you like puzzles?Euler did.Did you solve the one you heard for the lisening task?No!Well,don't worry,Euler didn't either!As he loved mathematical puzzles,he wanted to know why this one woudn't work.So he walked around the town and over the bridges of Kongsberg several times.To his surprise,he found that he could cross six of the bridges without going over any of them twice or going back on himself(see Fig 3),but he couldn't cross all seven.He just had to know why.So he decided to look at the problem another way.

你喜欢智力游戏吗?欧拉喜欢.
你解决了你听到的那个传说中的难题了吗?
没有!好了,别担心,欧拉也没有!
因为欧拉喜爱(攻克)数学难题,很想知道为什么这一个谜题无法解开.
所以他在镇里散着步,有好几次都从康斯博格的几座桥上经过.
让他惊讶的是,他发现他不用一座桥走两次或转身就可以过这七座桥中的六座(见图3),但他却无法跨越所有7座桥.
他必须得知道这是为什么.因此他决定从另一个角度来看这个问题.
这是关于离散数学的问题.数学方面的详细解释可以看http://163.21.82.150/DM/11GraphTheory.ppt#271,15,11-3 Vertex Degree :Euler Trails and Circuits
