问题 单项选择题

有A、B、C三个学校的足球队参加单循环赛,每两队都有一场比赛,比赛结果是:A队两战两胜,共失2个球;B队共进5个球,失球6个;C队有一场踢平,共进3个球,失球8个,则A队与C队之间比分情况一定是( )。

A.A平C 2:2
B.A胜C 4:2
C.A胜C 6:0
D.A胜C 5:0

答案

参考答案:D

解析: 整个循环赛中进球总数应该与失球总数相等,因此A队进球数为2+6+8-5-3=8(个)。
A队在循环赛中两战皆胜,因此平局应该为C队与B队踢平,设B队与C队比赛过程中B队进球数为x,同时失球数也为x,则B队在与A队比赛中失球6-x个,C队与A队比赛中失球8-x个,两队失球数等于A队进球数,即8-x+6-x=8,得x=3。因此可以算出A队与B队的比赛结果为3:2,A队与C队的比赛结果为5:0,B队与C队的比赛结果为3:3。

                                                                       Halloween

     History experts say Halloween goes back more than two thousand years to the Celts (凯尔特人) of ancient

Britain. October 31 was the Celtic Day of the autumn feast (宗教节日). On that day, priests (牧师) of the Celtic

religion (宗教) prayed that the spirits of the dead would retum to their homes for a few hours. The Celts built

huge fires to frighten away evil spirits released with the dead on that night.

     Hundreds of years later, the Roman Catholic (天主教的) Church made November first a day to honor

Christian Saints. It was called All Saints Day or All Hallows Day. The day before was called Hallow Eve or

Halloween. The name came from the church. But the traditions were closer to the old Celtic beliefs.

     People from Scotland and Ireland brought these traditions to America. Many people still believed spirits

played tricks on people on the last night of October.

     In the late 19th century, American boys helped the spirits with tricks of their own. On Halloween, they

would do things like changing street signs or putting a wagon on top of a house.

     American children continue to celebrate Halloween today. Many adults enjoy the holiday as well. They go

to holiday parties dressed as ghosts, monsters or famous people from history.

     Children continue these Halloween traditions by going out to "Trick or Treat". They dress as frightening

creatures or characters from popular movies. They go from house to house asking for candy. They may also

ask for money for the United Nations International Children's Emergency Fund (联合国国际儿童急救基金会).

They send the money to UNICEF to help needy children around the world.
