Robot Helpers

　　Where's the robot in my kitchen？Nowhere，of course.And he's probably not coming anytime soon.Robots do exist today，but mostly in factories and other working environments.

　　Back in the 1950s，however，people said that by now personal robots would be in most people's home.

　　So why hasn't happened？Maybe because robots are still too expensive and clumsy（笨拙的）.And probably the idea of robots cooking our dinners and washing our clothes is just too strange.At home we seem to be doing fine without them.

　　Telephones of tomorrow

　　In 1964 an American company introduced the video telephone.They said by the year 2000 most people would have a video phone in their homes.But of course the idea hasn't caught_on yet.

　　Why？The technology worked fine，but it overlooked something obvious：people desire for privacy.Would you want to have a video phone conversation with someone after you just stepped out of the shower?

　　Probably not—it could be uncomfortable！Just because technology doesn't always mean people will want to use it.

　　And finally，how about that crazy prediction of the flying car？It's not so crazy any more！But a flying car remains one of the most wonderful technology ideas to catch our imagination.Keep watching the news—or perhaps the sky outside your window—to see what the future will bring.
