  X-rays were first discovered by a German scientist, Wilhelm Konrad Rontgen, in 1895, almost by accident.He and several other scientists were experimenting with passing electric currents through certain gases in a special glass tube from which the air had been moved.One day Rontgen noticed that, even when the tube was covered with black paper, some strange kind of radiation was coming through and making a screen nearby glow.Ronghen could not see anything coming out of the tube, but then he discovered that if he put the screen in the next room on the other side of a closed door, the rays could pass not only through black paper but also through wood.

  The next thing he found out was that if he put his hand between the rays and a photographic plate, the rays would print a shadow of the bony framework of his hand on the plate.In fact, the rays could pass as easily through the fleshy part of his hand as through the black paper, but hardly at all through the bone.So Rontgen made the first X-ray picture of a hand, showing just how the bones in the hand fit together.

Mr Brown was going away for a week. Before he left, he said to his son, "if anyone asks for me, you can tell him that your father has been out for doing something, and will be back in a week, then be sure to ask him to sit down for a cup of tea."

 "OK, Dad," said his son. But he was afraid his son couldn't remember this, he wrote these words down on a piece of paper and gave it to him. His son put it into his small pocket, took it out and looked at it now and then.

 Four days passed, but no one came to see his father. The boy thought that there was no man to come and that the piece of paper was of no more use for him, so he burnt it that evening.

An old sea captain was often seen opening a small locked box, and looking inside. The crew’s curiosity grew and, on the day he retired, they rushed to cut the lock. There they found a sheet of paper that read, “Left—port(左舷). Right--- starboard(右舷).”
Are you afraid to make a mistake? If you made mistakes recently, maybe you need to hear about Roy Riegels.
The story is told about Roy and the 1929 Rose Bowl championship football game between Georgia Tech and the university of California. Shortly before halftime, Roy Riegels made a huge mistake. He got the ball for California and somehow became confused and started running in the wrong direction! One of his teammates tackled(抢断) him after he had run 656 yards, just before he would have scored for the opposing team. Of course, Georgia Tech gained a distinct(明显的) advantage through the error.
After the first half was over, Riegels sat in a corner, put his face in his hands and wept.
Coach Nibbs Price struggled with what to do with Roy. He finally looked at the team and said simply, “Men, the same team that played the first half will start the second.”
All the players except Roy went to the field. Though the coach looked back and called to him again, he remained seated in the corner. Coach Price went to him and said, “Roy, didn’t you hear me?”
“Coach,” he said, “I can’t do it. I’ve ruined you; I’ve ruined the school; I’ve ruined myself.”
But the coach Price put his hand on Riegels’ shoulder and said,” Roy, get up and go on back; the game is only half over.”
Roy Riegels went back and those Tech men will tell you that they have never seen a man play football as well as Roy Riegels played that second half.
The next time you make a mistake, it might be good to remember the ABC method.
A—Acknowledge(admit) your error and accept responsibility for it. Don’t try to fix the blame on other people or circumstances(客观环境). When you fix the blame, you never fix the problem.
B—Be gentle with yourself. The game is only half over. This is not the first mistake you ever made, nor will it be the last. You are still a good and caring person. Besides, later you may laugh at the mistake, so try to lighten up a bit now.
C—Correct it and move on. Correcting mistakes may also mean to amends(弥补过错),if necessary.
Now, go make your mistakes. And if you practice the ABC method, you’ll live to laugh about many of them.
67. The old captain kept a sheet of paper to_____.
A. give his men a lesson
B. arouse his crew’s curiosity
C. prove he was a good captain
D. tell “port” and “starboard” apart
68. From the passage we learn Coach Price______.
A. insisted on replacing Roy
B. decided to punish Roy after the match
C. criticized Roy for his serious mistake
D. encouraged Roy to finish the match
69. How was Riegels’ performance in the second half?
A. Very disappointing  B. Rather excellent  C. Fairly ordinary  D. Quite bad
70. The ABC method_____.
A. advised you to try to forget mistakes
B. helps you deal with mistakes

There was a king who gave his daughter a beautiful diamond necklace. The necklace was stolen and his people in the kingdom searched everywhere but could not find it. So the king asked to search for it and put a reward for$50,000 for anyone who found it.

One day, a clerk was walking home along a river when he saw something shinning in the river and when he looked, he saw the diamond necklace. He decided to try and catch it to get the $50,000 reward.

The old man could see this man was troubled. He again asked the clerk to tell him the problem and promised that he would not tell anyone about it. The clerk told him about the necklace and how he tried and tried to catch it, but kept failing.
