    In the traffic lights,red means "stop",green means "go",and yellow means "hurry": Why those colors, though? Why not blue,purple,and brown?The following are transponded from others WeChat.

●Red is an inherited symbol from railroads

    Red symbolizes danger in many cultures,which makes sense,considering it has the longest wavelength of any color,meaning you can see it from a greater distance than other colors.Red has meant "stop" since long before cars existed,with railway signals use of red dating bake to the days when mechanical arms lifted and lowered to indicate whether the rail ahead was clear.So that one's simple.

●Green meant "caution" at first

    Green's role in lights has actually changed dramatically over time.Its wavelength is next to (and shorter than) yellow's,meaning it's still easier to see than any color other than red and yellow.Back in the early days of railway lights,green originally meant "caution",while the "all-clear" light was,well,clear or white.Trains,of,course,take an unlimitedly long time to stop,and legend has it that several disastrous collisions happened after an engineer mistook stars in the night horizon for an all-clear.Thus,green became "go",and for a long time,railways used only green and red to signal trains.

●Yellow means "caution" because it's almost as easy to see as red

    From the earliest days of motoring up until the mid-1900s,not all stop signs were red-many were yellow, because at night it was all but impossible to see a red stop sign in a poorly lit area.The yellow stop-sign craze began in Detroit in 1915,a city that five years later installed its first electric traffic signal,which happened to include the very first amber traffic light,at the corner of Michigan and Woodward Aves.

    Many parents have learned the hard way that what sounds like open communication is often the very thing that closes a youngster's ears and mouth. One common mistake is the Lecture, the long monologue that often starts with “When I was your age” Eighteen-year-old Kelly calls lectures “long, one-side discussions in which I don't say much.”

    Kids reflexively(条件反射地)shut down in the face of a lecture. Their eyes glaze over(呆滞),and they don't register any incoming information. Listen to 13-year-old Sarah describe her least favorite times with her mom and dad. “First, they scream. Then comes the ‘We're so disappointed' speech. Then the ‘I never did that to my parents' lecture begins. After that, even if they realize how ridiculous they sound they never take it back.”

    Lines like “When you have children of your own, you'll understand” have been seriously said by parents since time immemorial. But many of our expert parents, like Bobby, a registered nurse and mother of three, feel that by falling back on clichés(陈词滥调)to justify your actions, we weaken our position.

    Since kids are creatures of here and now, the far-off future has no relevance to them. Therefore, good communicators like Bobby suggest, “Give specific reasons for your actions in present language: ‘I'm not letting you go to the party because I don't think there will be enough adult supervisions.'”

    Betty, who lives in Missouri, uses an indirect approach. “I find that warnings are accepted more readily if I discuss a news article on a subject I am concerned about. My husband and I talk about it while our children absorb the information. Then they never think I'm preaching(布道).”

This really helped when Betty's kids began driving. Instead of constantly repeating “Don't drink; don't speed,” she would talk about articles in the paper and express sympathy for the victims of a car crash. Betty made no special effort to draw her kids into the conversation. She depended on a teenager's strong desire to put in his opinions—especially if he thinks he isn't being asked for them.

    The exhibition explores the impact the cruel reality of war had on colonial sportsmen and their loved ones as they were transplanted from the rugby fields of home to fight.

    He looked like a pirate.

    With his handkerchief tied in a knot behind his little nine-year-old head, he looked like a pirate, a sad pirate. The first time little David came to our camp, he was hairless and worn out from medical treatments. He was also very angry.

    Paul Newman's camp counselors (指导老师) were hoping to fill David's days with fun and laughter. But David stayed inside himself, wanting to be alone, or in a corner of the cabin. At this camp for children with life-threatening illnesses, we had seen some pretty tough children worn out by cancer recover full of energy despite their illness. But we saw little progress in David no matter what we tried with him. Five days into the eight-day session saw a quiet, sad little pirate.

    Then something happened on that fifth night. Something at camp that we would call "huge". It was cabin night. That's the time when campers and counselors spend time together in each individual cabin instead of an all-camp activity. Campers love cabin nights because there's always a bedtime snack. On the cabin table that night were bags of potato chips.

    David slowly walked over to the table, leaving his comer to join the rest of us. He took one of the bags of the potato chips and started smashing(弄碎) it with his little fists, as all the other campers looked on in disbelief, I wondered what the cabin counselor would do.

    The college-age volunteer counselor positioned a bag of chips on die table in front of himself, and he, too, started smashing it with his fist. The campers went crazy as everyone ran to the table to get in on the fun of smashing potato chips with their fists.

    Somehow everyone knew, everyone sensed, that anger within him was now being released.

    For the last couple days of the session, David was a different kid. He was a little nine-year-old boy again, trying to fill the hours of each remaining day at camp with as much fun as could be possible.

    Several days after the session, David came back again. This time, there wasn't anything he wouldn't try to fit in to his day. He sure was having a great time at camp. David asked me if I needed an altar(祭坛)boy when I celebrated Mass in the woods. Sure enough, he was my altar boy. I remembered how carefully he listened to me when I talked about death. I said it's only a doorway. You walk through the door and there's the Lord God and behind God a whole line of people waiting to hug you.

    After Mass, he said to me, "Hey Fatha, a door, huh?"

    A couple more days of fun passed and tonight was the talent show. The tradition is that campers and counselors dress up in costumes, and everyone gets a standing applause for singing and dancing or simply just acting like fools on stage.

    The show had begun: lights, camera, action.

    Unfortunately, the only action taking place in our row of seats was little David making his way from counselor to counselor to say an early good-bye to camp. He had become quite ill and had to go to the hospital because of this new crisis.

    When this little nine-year-old pirate stood in front of me, he gave me a hug and a big wet kiss on my cheek. I was crying. He was crying. A whole row of counselors was in tears. After the hug and kiss, he put his hands on my shoulders, and tears still in his eyes, said: "See you on the other side of the door, Fatha."

    1990 was a significant year in world events. In February, Nelson Mandela was set free after 27 years in prison. In October, East and West Germany became one country again. Then at the end of 1990, the World Wide Web was born. For this final event we have one man to thank, Tim Berners-Lee, the father of the Web.

    Berners-Lee was born on June 8, 1955 in London, England. His parents, both computer designers, encouraged him to think and work creatively as he grew up. He was an excellent student and naturally took an interest in computers and science.

    After graduating from Oxford University, Tim went to work at a science research center in Switzerland. There he developed some of the different systems that would later become the Web. The first was HTML, the computer language used to make web pages. The second was an address system that let computers anywhere find each other and send and receive information. In 1990, while still at the science center in Switzerland, he put them together to make the first Internet browser. It could run on any computer and allowed people to share their information with the rest of the world.

    Tim knew that the more people used the Web, the more useful it would be. He wasn't interested in money but knowledge, so he gave out his invention for free to anyone who was interested. Many were interested and the growth of the Internet began.

    Today Tim works as a professor at the MIT in America, researching new and interesting ways to use the Web. He has received many awards from governments and organizations for his efforts. He is still not very interested in money. That is why he is so admired by his students and workmates. It may also be one of the reasons why few people outside the world of technology know his name.
