问题 单项选择题

学校举行象棋比赛,共有甲、乙、丙、丁4支队。规定每支队都要和另外3支队各比赛一场,胜得3分,败得0分,平双方各得1分。已知:
(1)这4支队三场比赛的总得分为4个连续的奇数;
(2)乙队总得分排在第一;
(3)丁队恰有两场同对方打成平局,其中有一场是与丙队打成平局的。
问丙队得几分( )

A.1分
B.3分
C.5分
D.7分

答案

参考答案:A

解析: 每支队均比赛3场,因此最高分不超过9分,又知总得分为4个连续的奇数,因此得分有3、5、7、9和1、3、5、7两种情况。若最高分为9分,那么排名第二的总得分只能是偶数6、4、2,不符合题意,排除。故乙队得7分,即2胜1平。由条件(3)知,丁队恰有两场同对方打成平局,积分2分,为偶数,故另一场只能为胜,共得5分。由此可知,丙队得分为1或3分。由于丁队一场未败,故乙队获胜的两场只能是甲队和丙队。目前已知丙队战两场,一负一平,积1分,另一场无论是胜或平,积分均为偶数,故这一场只能为负,总积分为1分。本题正确答案为A。

    Electronic monitoring devices, mobile phone detectors and giant screens connected to

close-circuit TV cameras. Does it sound like a high security operation? Well, the National

College Entrance Examination (NCEE) in China is nothing less than that.

    The education authorities' efforts to prevent cheating at the exam have gone almost

unnoticed. The authorities launched the country's new monitoring system for the all-

important exam yesterday. The system is based on local schools' networks and is connected

to provincial headquarters, especially set up for the exam. The government has plans to

cover all the 31 provinces and regions in the next three years and offer the services for

other national exams, too.

    The records of students caught cheating during national tests, such as the college

entrance exam, would be stored in the system and made available online for higher

educational institutions' and future employers' reference.

    But despite all these measures, cheating remains a big temptation for some candidates.

The number of students caught cheating in last year's NCEE was 3,000, up from 1,300 in

2005. But this is hardly surprising because passing the NCEE is the only way most of the

students can get access to higher education.

    10.1 million students registered for this year's NCEE, 9.6 million taking the exam,

but only 5.67 million would enter college. Among the successful candidates will be about

500,000 with special merits who will be admitted to universities directly, which means

roughly 13 in every 24 candidates can actually enter college. That should explain why

some students are tempted to cheat during the exam.

    Cheating in such a well-monitored exam is not an easy thing to do, says an MOE

official, and it's very risky business too. The chance of a student getting away with

cheating is minuscule. And if caught, he/she risks ruining his/her entire career because

higher educational institutions and potential employers can always check his/her record.

1. The passage is most probably taken from _____. [ ]

A. a politics textbook.

B. a fashion report.

C. a reference book.

D. a newspaper.

2. According to the passage, what will happen if a student is caught cheating in the NCEE? [ ]

A. He/She will lose the chance to sit for more exams.

B. His/Her behavior will be recorded, stored and made available online.

C. He/She will get no records and lose the opportunity to go to college.

D. He/She will be blamed and his/her career and life will be put an end to.

3. The underlined word"minuscule" in the last paragraph probably means _____. [ ]

A. tiny

B. impossible

C. difficult

D. incredible

4. We can draw a conclusion from the passage that _____. [ ]

A. the education authorities are making great efforts to prevent cheating in exams

B. although it is very hard to succeed, many students take a chance to cheat in exams

C. honesty is still the best policy when it comes to exams

D. it is not easy to get access to higher education in China
