  12月4日CNN聽力:美國加州聖伯納迪諾產生槍擊案 將來或能實現電話全息影象技巧

  

  This is CNN STUDENT NEWS.

  I'm Carl Azuz at the CNN Center,starting with somebreaking news from yesterday.

  There was a mass shooting at a conference centerin San Bernardino, California.

  It's a city east of Los Angeles.

  Police say, quote, "upwards of 14 people were killedand upwards of 14 more were injured."

  Officials did not know yesterday if this was a terrorist attack.

  Witnesses reported seeing three gunmen who were believed to drive away in a SUV after theshooting.

  A CNN security analyst says that suggests the attack was planned in advance.

  Teachers, CNN.com will have the latest details on this incident.

  Next today, after the November 13 terrorist attacks in Paris, France's government asked itsallies to increase their military action against the ISIS terrorist group.

  The governments of Britain and Germany are considering doing exactly that.

  And the U.S. is expanding its military involvement in Iraq.

  America is adding a new strike force to the 3,000-plus U.S. troops who are currently in theMiddle Eastern country.After frequent White House denials that U.S. troops would facecombat in Iraq and Syria…

  Today, the president is ordering dozens of U.S. Special Forces into combat roles involvingdirect action against ISIS.

  These Special Operators will, over time, be able to conduct raids, free hostages, gatherintelligence, and capture ISIL leaders.

  The new expeditionary force will number in the dozens.

  Those support forces will expand its total footprint to about 200.

  This force and the operations this force will conduct will provide us additional intelligencethat will make our operations much more effective.

  Part of their mission, raids like this one in northern Iraq in October, daring joint operationsinvolving Kurdish commandos and the U.S. Army's Delta Force to free these ISIS-heldprisoners.

  Demonstrating the added danger of direct action, one Delta Force Operator Master SergeantJoshua Wheeler was killed.

  This new deployment to Iraq is in addition to the 50 Special Forces the U.S. is deploying on theground in Syria.

  It puts everybody on notice in Syria that you don't know at night who is going to be coming inthe window.

  And that's the sensation that we want all of ISIL's leadership and followers to have.

  So it is an important capability.

  The expanded U.S. combat role comes in the aftermath of Paris.

  And, as progress against ISIS on the battlefield has been halting.

  OK. Now for something that blends history, journalism, science, media,we're kicking off a two-part series today that looks at the past and the potential future of communication as weknow it, most changes in the way two people are able to reach each other, have been tied toand limited by the technology available to them.

  Of course, it's possible for us to speak to someone else live at virtually any other place onearth.

  What's next could be an illusion.

  How we communicate, how we say hello, how we stay in touch has changed dramatically, goingback from the mid-19th century, it's been something of an epic story.

  The telegram developed in 1844 by Samuel Morse, the inventor of the Morse code, allowed usto stay in touch over long distance.

  The first message read, "What hath God wrought?"

  1876 saw the telephone ring for the first time, invented by a Scotsman Alexander Graham Bell.

  The first words he uttered, "Mr. Watson, come here.

  I want to see you."

  By 1960, we could talk to each other from anywhere on earth, via satellite, thanks to the Echo 1satellite launched by NASA.

  The first electronic message or email was sent in 1971 by Ray Tomlinson, an American computerengineer.

  His message simply said, "QWERTYUIOP", or the top 10 letters on the keyboard.

  By 1973, we have the first cellphone developed by another American, Martin Cooper.

  It was known as "The Brick".

  But the great game changer came in 1991, the World Wide Web, invented by a Britishcomputer scientist Tim Berners-Lee.

  It led to everything we have today, Skype, Twitter, Facebook, a new world of onlinecommunication.

  So, can we expect next?

  Well, what better for inspiration than the movies?

  Everybody remembers the scene Princess Leia sending an SOS in 1977 movie "Star Wars".

  Well, a scientist in California is absolutely convinced that we're all be communicating just likethis, holographically, pretty soon.

  David Fattal is a French-born physicist.

  His field, controlling and manipulating light.

  We've invented a new type of display, a holographic display able to produce interactivehologram at the tip of your finger, in the palm of your hand for cellphones and for the future ofdisplays.
