问题 单项选择题

某校举办数学竞赛,A、B、C、D、E五位同学取得决赛权,另外六位数学爱好者对他们的决赛成绩进行预测:
第一个人说:B第一,D第四; 第二个人说:B第二,D第四;
第三个人说:E第一,A第四; 第四个人说:C第二,E第五;
第五个人说:D第二,B第三; 第六个人说:C第三,A第五。
决赛结果,他们六人都只猜对了一半。问这五位同学的实际名次如何谁是第一名( )

A.A
B.B
C.C
D.E

答案

参考答案:D

解析: 本题可以用假设的方法,第一种情况:假设B第一正确,那么D第四就错误,第二个人说的则B第二正确但是与第一个人的又相矛盾。所以,第一种假设不成立;第二种假设, D第四正确,第五个人D第五则错误,B第三则正确,依次往下推,最后得出A、B、C、 D、E的名次分别为:⑤③②④①。故选D。

Saturday, June 16th  

In the morning, we went camping along a path in Green Natural Park. We were happy because it was a sunny day. We were expecting an enjoyable two-day holiday. On the way, we kept singing and making jokes.

However, in the afternoon, when we finished our picnic at one o’clock, it was dark and windy. Soon, there was a shower. Unluckily, none of us brought an umbrella. We ran about but we could find no place to hide.

Twenty minutes passed and it was still raining, There were hours to go before we reached the campsite (野营地). It was even worse that our small compass (指南针) showed that we went to the wrong way. We had lost our way! 

We had to make a quick decision as it was raining heavily. Chris said we could set up a tent to hide in, so Mary and Tom helped to set up the tent. Chris and I tried to make a fire to keep us warm. But we were unable to light the fire, as everything was wet. We dried ourselves, chatted and waited inside the tent. At about five o’clock, it stopped raining. We decided to give up the camping trip because all of us had been very tired.

This camping trip may not be very successful but we know each other better. And the most important thing I’ve learned from this trip is the importance of team spirit.
