问题 解答题

某小学有六名乒乓球选手进行单打循环赛.比赛在三个台上同时进行,比赛时间是每星期六的下午,每人每周只能而且必须参加一场比赛,因而比赛需要进行五周.

已知在第一周的星期六C和E对垒;第二周B与D对垒;第三周A和C对垒;第四周D和E对垒.当然,在上述这些对垒的同时,另外还有两台比赛,但这两台比赛是谁和谁对垒,我们不清楚.

问:上面未提到过名字的F在第五周同谁进行了比赛?请说明理由.

答案

由题意可知,第一周C同E,第三周C同A进行比赛,

因而C同D、B、F的比赛只能在第二、四、五周了;

由于第二周D同B对垒,因而这一周C就只能同F比赛了.

同理可推得在第四周C同B,第五周C同D对垒.

用同样的分析方法可推知第一周D同A,第二周D同B,第三周D同F,第四周D同E,第五周D同C对垒.

由于每周都有三台比赛,知道了其中两台选手,

由此推得在第五周F同E进行了比赛.

所以,第五周F同E进行了比赛.

      We may be very pleased with the rapid progress we have made in every field of study. But the

way to test a student's knowledge and ability still remains as poor as it was, We have almost done

nothing to improve our examination system.

      It is well known that the examination system we are now using may be a good way of testing a

student's memory, but it can tell you nothing about a student's ability. It does no good to students

and teachers.

      As soon as a child begins school,he enters a world of examination that will decide his future of job.

      In fact a good examination system should train a student to think for himself. But it now does

nothing about that. So students are encouraged to member what is taught. It does not enable them to

gain more and note knowledge. The students who come out first in the examination often may not be

the best in their studies. 

     Besides, the examinations often force teachers to train students what to do with the coming

examination from time to time. There must be some simpler and better way to test a student' s ability

besides knowledge. And that is what we should do at once.
