Tom: Hey, Bob,what are you d oing?
Bob: I am playing game,call ed “Warcraft”
Mary：It seems you are very busy.
Bob: Yes,I always have no time to respond my companions in the game. John：Don’t worry, it will be achieved the interaction between human being and PC in future.
Mary：Can you say it in d etails?
John：British scientists are researching about the interactivity of connecting the real worl d and the virtual worl d. This technic can make your PC or game consol e d o the related responds through id entifying your expressions.
Tom: Woo,it is so cool.you know，School has ad d ed several new courses to our grad e this semester. I have more homework to do now.
Mary：What's your favorite course,Bob?
Bob: I like science most.
John：Science? That's a surprise.
Bob: Surprise?
Tom: We thought you woul d like PE.
Bob: I d o like PE, but I am interested in science.
Mary：What about you，Tom？
Tom: My favorite course is science ,too. Through this course, I can l earn more about the world around us cl early.and there is no d oubt that science development make our life more col orful.
Mary: But as i know,science d evelopment not always brings the good news . Bob: Why are you say that ?
Mary: You know,With the d evelopment of science,it also brings peopl e some environmental pollution.Such as electronic pollution,space pollution,light pollution and so on......
Tom: I d o agree with you,but i al so believe that the prospects of science d evel opment are brightening.,science technol ogy can d eal with these environmental pollution which brings by science d evel opment.
John：It seems that you know a l ot about science ,Your parents woul d be happy if they knew that. Because you are always a naughty boy.
Tom: Naughty? I'm just cl ever. And I wish i coul d be a person like Dennis Hutton someday.Do you know about Dennis Hutton, the scientist?
Mary:I know. A inventer and physicist, the son of a farmworker.
Bob: He graduated at 17 with the first class degree in physics and mathematics. He mad e his first not abl e achievement at the age of 18. It was a method of refrigeration which rolls from his work in l ow temperature physics.
Mary:He became professor of mathematics at the University of Manchester at 24, where he remained for twelve years. During that time, he married one of his stud ents.
John：wow. Anything else?
Bob: Later working together in Lond on, they laid the foundations of mod ern physics by showing that normal laws of cause and effect d o not apply at the l evel of subatomic particles. For this he and his wife received the Nobel Prize for physics in 1910 .
John：But I have heard that he had went to America ,so when did he go to America?
Tom:Let me see. In 1920 he went to teach in New York and died there sudd enly after only three weeks. In his lifetime, Hutton patented 244 inventions.
Mary:what a great scientists he is ! I’m sure that Scientists like him will speed up the process of the worl d. Let’s l ook forward to it.
Bob: I really anticipate it very much!
John：Tom,we all expect to hear your good news of being a scientist like Dennis Hutton,maybe someday we will be proud of you .
Tom:I hope I will not disappoint all of you .but the most important thing is shall we have lunch now ? It’s already 12 o’cl ock and I am really hungry.
Bob: Ok ,let’s go.
