各位XDJM,以下这道题我没搞明白究竟想考什么,请指点一下,谢谢了。

The participants in a race consisted of 3 teams with 3 runners on each team. A team was awarded 6-n points if one of its runners finished in nth place, where 1≦n≦5. If all of runners finished the race and if there were no ties, was each team awarded at least one point?

(1)No team was awarded more than a total of 6 points.

(2) No pair of teammates finished in consecutive places among the top five places.

我的理解,按照题干,每个队员只要比赛就至少可以得到一分,3个队员可以得到至少3分,题目是每队是否至少得到一分,这个问题本身就没有必要。不需要看下面的(1)和(2)就可得出答案。可我想我一定理解有问题,因此请大家指教。究竟这道题是什么意思。再次感谢。

我觉得不是,应该是一共有9个人,前五名分别得5、4、3、2、1分~~

总的分数是15分

1)说3个组里没有总分超过6分的,即最多6分,最少分的组至少有3分~~


2)说没有队友是排名在一起的,即可能有一组得了5、3、1三个分,另外一个组得了4、2分,还有一组没~~~

所以应该是A吧~~

愚见~大家指教~
