问题 填空题

A、B、C、D四名运动员赛跑,比赛后有人问他们各自的名次.

A说:我不是第一,也不是第四;B说:我不在最后;

C说:我跑的最快;D说:我跑在最后.

事实是,他们中有三人说对了,一个人说错了,又知道他们没有出现同时到达终点的情况.

问:第一名是______,第四名是______.

答案

假设A说的“我不是第一,也不是第四”是错误的,即A是第一或最后一名;、

则C与D两人中其中一人必是错的,即此时有两人是错的,与题意相矛盾.

即A说的是对的,则A是第二名或第三名;

如B说的是错误的,则B在最后,与D相矛盾,则B说的是正确的.

此时,已知A,B都不在最后,如C在最前是错误的,则D在最后是正确的,

由于此时A不在最前或最后,C在最前是错的,D在最后,又B不在最后,则B在最前,D在最后,与题意相符.

即第一名是 B,第四名是 D.

故答案为:B,D.

Reading is very important to help you learn English. To learn as much as you can from reading, you need to read different kinds of English. This book provides not only different kinds of English but also a good way to check your reading ability.

There are four parts in the book:

Part 1 is Messages: In this part somebody wants to send information in writing to somebody else. There is a test on timetable and a test on text messages.

Part 2 is People: In this part all the tests are about people. For example, there is an informal letter between friends. There is formal(正式的) English in biography(传记). There is a job application as a model to help with your writing, as well as testing your reading.

Part 3 is Places: In this part, too, many different kinds of English are shown, some informal and some formal. There is the informal English of a holiday postcard. There is also the formal English in a letter of complaint.

Part 4 is Things: You will find some descriptive writing in this part. There are descriptions of clothes and of a computer.

You can do these tests in any order you like, or you can do all the tests with a formal or informal text. I enjoyed writing this book and I hope you enjoy using it.
