There was an engineer who had an exceptional gift for fixing all mechanical (机械的) things. After serving his company heart and soul for over 25 years, he happily retired(退休). Several years later his company telephoned him regarding a seemingly impossible problem they were having with one of their multi-million-dollar machines. They had tried everything and everyone else to get the machine fixed, but no help.
In desperation (绝望), they called on the retired engineer who had solved so many of their problems in the past. The engineer unwillingly took the challenge. He spent a day studying the huge machine. At the end of the day he marked a small X in chalk on a particular part of the machine and proudly stated, "This is where your problem is.” Tile part was replaced and the machine worked perfectly again.
The company received a bill for $ 20,001 from the engineer for his service. They told him to make a list of his charges.
The engineer answered brie
A. after he worked in the same company for less than 25 years
B. after he worked in different companies for 25 years
C. after he worked faithfully in the same company for over 25 years
D. after he worked heart and soul in his own company for 25 years
Some young soldiers who had recently joined the army were being trained in modern ways of fighting, and one of the things they were shown was how an unarmed man could trick an armed enemy and take his weapon away from him. First one of their two instructors took a knife away from the other, using only his bare hands; and then he took a rifle away from him in the same way.
After the lesson, and before they went on to train the young soldiers to do these things themselves, the two instructors asked them a number of questions to see how well they had understood what they had been shown. One of the questions was this: "Well, you now know what an unarmed man can do against a man with a rifle, imagine that you are guarding a bridge at night, and that you have a rifle. Suddenly you see an unarmed enemy soldier coming towards you. What will you do "
The young soldier who had to answer this question thought carefully for a few seconds before he answered, and then
A. before being instructed
B. after being instructed
C. while being instructed
D. two days later
