问题 单项选择题

甲、乙、丙、丁、戊五人值班,从星期一到星期五,每人各值班一天。要求:乙排在丁、戊两人之前,丙不能排在星期二,甲和丁之间恰好隔开一天。问乙排在星期几时,五人的值班顺序是唯一的()

A.星期一

B.星期二

C.星期三

D.星期五

答案

参考答案:C

解析:根据“乙排在丁、戊两人之前”,可知乙不能排在星期四和星期五。如果乙排在星期一或星期二,则显然丁和戊的顺序都有多种选择。当乙排在星期三时,丁和戊只有排在星期四或星期五,又“丙不排在星期二”,则丙排在星期一,甲排在星期二;又由“甲和丁之间恰好隔开一天”可知,丁排在星期四,戊排在星期五,五人的值班顺序是唯一的。选C。

     Everybody in this world is different from one another.But do you know that understanding differences

can help you better manage your money?

     As we grow up, we gradually develop a set of  our own values or beliefs. These are  influenced  by

society,our family,the education we receive and so on. Once this value system is set up,it's not easy to

change later in life.

     Financial experts say that everyone also has their own belief of how to manage their finances.This is

part of our value system and it has a great impact on the way we look after our money.

     According to our different values,experts put us in three categories.They are:the ant,the cricket and the

snail.

     The ant-works first

     Just like ants who work heart and soul in summer in order to store food for winter,these people don't

care about enjoying the moment.They work very hard and save money they earn so that they can enjoy life

when they get old and retire. The ant loves to save but they could make more out of  their money if  they

were willing to invest in some funds and stocks with low risk.

     The cricket-fun first

     The cricket wants to enjoy everything now and doesn't think  too much about the future. They even

borrow money when they really want something.Many young people now belong to this group.These

people have little savings.When they get old,they might have problems.They should learn to save and buy

insurance.

     The snail-lives under pressure

     The snail refers to people who make life difficult for themselves.They take big long-term loans from

the bank in order to buy things such as luxury houses.They are happy to take big loans even though they

are not sure  whether they can afford it. This can cause  problems in the future. They should plan more

carefully.
