My mother was telling me about how she and her family got their first television when she was a teenager. Of course, it was black and white. She said she only watched it at night.
When I was young, we had only about 3 or 4 different channels. My brothers, my sisters and I would sometimes fight about which channel to watch. But we usually enjoyed the same shows.
Nowadays, we can get hundreds of channels on TV. There are channels with old movies, cooking, fishing and so on. It's amazing! I wonder how much my brothers, my sisters and I would fight if we had hundreds of channels when I was a child. Of course, we had only one television set.

Eight hundred years ago，a man in southern Turkey invented an amazing clock.It was more than 7 meters high.At is base（基座）was a life﹣size model elephant.Every half hour，something amazing happened.The whole clock came alive Model birds，dragons，and people started to move.
The clock's inventor was an engineer named al﹣Jazari He lived in Turkey.Al﹣Jazari was probably one of the greatest engineers in history.Some historians call him "the father of modern﹣day engineering. "
We know about al﹣Jazari mostly from a book that he wrote._________They include clocks and hand﹣washing machines.The book also has drawings that show how each machine works.
Many everyday things today﹣from toys to car engines（发动机）--still use al﹣Jazari's ideas.Without his machines with moving parts，we might no have modern﹣day robots.
Today，it is still possible to see what al﹣Jazari's elephant cock looked like.A full﹣size working mode is in Dubai's Ibn Battuta Mal.There，every half hour，al﹣Jazari's most amazing invention comes to life once again.
How Does the Elephant Clock Work？
A bowl with a small hole floats（浮）in a water tank（水箱）inside the elephant's body.As the bowl slowly sinks（下沉），it pulls a rope that moves a human figure.His moving pen shows the number of minutes past he hour.
Every half hour，the water bowl becomes full and sinks completely. Thiscauses a ball to fall from the top of the clock.The movement of the ball causes a phoenix to move and make a sound.
The ball then drops out of a falcon's mouth into the mouth of a Chinese dragon.The weight of the ball causes the dragon's head to move down and the dragon's tail pulls the water bowl back up.
Finally，the ball drops out of the dragon's mouth and into a vase.As the ball lands in the vase，the elephant driver moves and makes a sound.The cycle begins again until there are no more ball in the top of the clock.

Ever wondered why your virtual（虚拟的）home helper doesn't understand your questions？Or why your navigation app took you on the side street instead of the highway？In a study published April 21st in the journal Science，Italian researchers，Arianna Pipitone and Antonio Chella，designed a robot that "thinks out loud".
To explore how inner speech might influence a robot's actions，the researchers built a robot called Pepper that speaks to itself.It has the ability to reason and think.They then asked people to set the dinner table with Pepper according to etiquette（礼仪）rules.In one experiment，the user asked Pepper to lay the napkin at the wrong place，going against the rules.Pepper started asking itself a series of self﹣directed questions and concluded that the user might be mistaken.To be sure，Pepper confirmed the user's order，which led to further inner speech.
"Ehm，this situation troubles me.I would never break the rules，but I can't make the user unhappy，so I'm doing what he wants，" Pepper said to itself，laying the napkin where it was required to be.Through Pepper's inner voice，the user can learn Pepper was facing a difficult situation and solved it by prioritizingthe user's order.
Comparing Pepper's actions with and without inner speech，Pipitone and Chella discovered the robot had a higher task﹣completion rate when having self﹣dialogue.
However，some people find the robot spends more time completing tasks when it talks to itself.The robot's inner speech is also limited to the knowledge that researchers gave it.Pepper's designers still say their work provides a framework（构架）to further explore how self﹣dialogue can help robots focus，plan，and learn. "In some ways，we are creating a generational（世代的）robot that likes to chat.From navigation apps and the camera on your phone to medical robots in the operation rooms，machines and computers alike can take advantage of this chatty feature，" says Chella.
