　　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．

One evening, I came across one of my son’s papers with a failing grade. I almost started to yell his name 31 I suddenly remembered he was in bed asleep. It was his 32 (nine) year of school and his academic career seemed to be in ruins, so I was angry. But I put the paper aside and turned to the 33 one, at the top of which were written “My dad”. It was a poem about me, 34 included the time I had to leave work to take him to the hospital because he 35 (break) his finger. So careless was I 36 I had forgotten all about that.

He talked about how I wrestled with him in the evenings and 37 good many other things. That paper was suddenly not nearly as important as it had been a few minutes 38 . I don’t know if he planted the poem next to the failing grade to 39 (soft) the blow, but it worked. Instead of a severe lecture, I talked to him about the poem as well as the failed homework, and it began to make sense to me that I could include praise along 40 constructive criticism.

“Cool”is a word with many meanings．Its old meaning is used to express a temperature that is a little bit cold．As the world has changed，the word has had many different meanings．
“Cool”can be used to express feelings of interest in almost anything.When you see a famous car in the street，maybe you will say，“It's cool．”You may think，“He's so cool，”when you see your favourite footballer．
We all maximize（扩大） the meaning of“cool”．You can use it instead of many words such as “new” or “surprising”．Here's an interesting story we can use to show the way the word is used．A teacher asked her students to write about the waterfall（瀑布）they had visited．On one student's paper was Just the one sentence，“It's so cool．”Maybe he thought it was the best way to show what he saw and felt．
But the story also shows a scarcity（缺乏）of words．Without “cool”，some people have no words to show the same meaning．So it is quite important to keep some credibility（可信性）．Can you think of many other words that make your life as colourful as the word “cool”？ I can．And I think they are also very cool．
