问题 单项选择题

一户人家养了四只猫,其中一只猫偷吃了他家里的鱼。主人对它们进行审问,只有一只猫说真话。这四只猫的回答如下: 甲:“乙是偷鱼贼。” 乙:“丙是偷鱼贼。” 丙:“甲或者乙是偷鱼贼。” 丁:“乙或者丙是偷鱼贼。” 根据以上陈述,请确定以下哪项陈述为假

A.甲不是偷鱼贼。

B.乙不是偷鱼贼。

C.丙说真话。

D.丁说假话。

答案

参考答案:A

解析: 此题属于演绎推理型,涉及有关直言命题和复合命题的推理以及逻辑基本规律的知识。当心考题是从反面设问。 如果甲说真活,则丙和丁都说真话;根据题干,只有一只猫说真话,故甲肯定说假话,乙不是偷鱼贼。如果乙说真话,则丁也说真话,与给定前提矛盾,故乙说假话,丙不是偷鱼贼。由此可知,丁说假话,故丙说真话,甲是偷鱼贼。所以,A项必定为假。正确选项是A。

FOR Chinese students the end of their senior year is filled with studying and stress as they prepare for the college entrance exams in June.But for American high school seniors the experience couldn’t be more different. The end of senior year is a celebration of their time in high school and involves parties,games and fun.

Senioritis is a commonly used expression.It means seniors have a disease which makes them unable to do work.This starts in April when seniors find out whether they have been accepted to university.

Unwilling to do school work,seniors have plenty of other activities to focus on.

Many schools have a “Senior Show”,in which only seniors are allowed to perform.Some seniors sing or dance but many of them perform skits(滑稽短剧),where they make fun of their favorite teachers or their friends.For example,a group of boys may dress up and imitate a group of their friends.It is all light-hearted.

The“Senior Show”is usually a part of Senior Week,which is a week specifically dedicated(专用的) to seniors.During this week,seniors usually get academic or athletic awards they have won over their high school careers.The seniors also vote for one of their male and female classmates who they believe is the best-looking or funniest or most involved,etc.These are then published in the yearbook.

The yearbook is an important part of high school for seniors.It is usually dedicated to them and has all their pictures and some words from them in it.Then seniors go around and get it signed by their friends so they can always remember their time together.

Of course during all of this time,seniors are preparing for the Senior Prom,which is an important moment in American culture.It is the most important dance in a young American’s life.

The end of senior year is a truly special and wonderful time for American students.It’s something they will remember for the rest of their lives.
