第41—45题基于以下题干：
在连续举行的为期五天的烹饪大赛期间，每天都有一位名厨师现场表演烹饪绝技。这五位名厨师分别是：G、H、J、K和L。他们每人表演一天。表演的时间安排受下列条件限制：
(1)H不能排在前二天表演。
(2)L必须排在H之前的某一天表演。
(3)J必须排在G之前的某一天表演。
(4)G必须排在K之前的某一天表演。

如果J不能排在第一天表演，则下列哪一项必定为真( )

A．G不能排在第三天表演。

B．H不能排在第四天表演。

C．J不能排在第二天表演。

D．L不能排在第三天表演。

答案

参考答案：D

解析：

[分析]：根据条件(3)和(4)可推出G、J、K的排列顺序为：J＜G＜K。因此，G和 K不能排第一天。根据条件(1)可知H也不能排第一天。现在如果J不能排在第一天，则只能是L排第一天。
由于受条件(1)的限制，H只能排第四天或第五天，再加上已指出J＜G＜K，所以这五名厨师的排列顺序为：

Many years ago I drove a taxi for extra money. I drove mainly from the downtown to the 16 , beside the Greenwood Racetrack which was in operation at that time.
Each time a taxi drove up to the station, many kids would run along the   17  to the passenger door. One   18   kid would open the passenger door and say, “ 19  , sir.” The passenger would always say thanks and give the kid a   20   on his way from the taxi to the entrance of the track. It was a routine that everybody knew.
One day I noticed a boy, who was   21   than most of them but was pushed away by even the smallest kid. He never pushed back.   22  , he would even step aside when others pushed forward. But he never   23  .
Then one morning as I was   24   to the sidewalk, all the other kids were running after a taxi   25  mine. They didn’t notice mine.
The boy saw me and walked toward my taxi. As I pulled up I made sure that I stopped in a 26  with the passenger door right beside him. He   27  the passenger door with a flourish(夸张动作) and said, “Good luck at the track, sir.”
28 , the man did not tip him a quarter. Instead he   29 , “Get out of my way!” He pushed him aside so   30  that the boy fell on the sidewalk and I knew he was badly hurt. I got out of my car quickly   31  find that the man disappeared in the crowd.
So I looked for the kid. I decided to give him $20 for all his   32 . But he was far up ahead, walking out of the station   33 . The traffic policeman waved at me to get my car going.   34 , I never saw him again. I’d like to find him one day and tell him that if only he had stuck around a little longer I would have given him a whole $20.
I learned an important lesson from the boy. When things seem so   35  that you are ready to give up, that is the time when things are most likely to turn around for you.
