Having grown up in northern Arizona, I believe that the southwestern state is home     1     the most beautiful landscapes on the planet. That is, until I     2     (invite) to explore Guizhou province by an organization many years ago. There is nothing like seeing with one’s own eyes.

My father used to drag my brothers and me on     3     (fish) trips around Arizona. We would compete to catch the     4     (large) fish. On my trip to Guizhou I had the opportunity to canoe on Wanfeng Lake,     5     I enjoyed the silence and took in the surrounding karst mountains.

During my trip around     6     city of Xingyi, in Guizhou, I saw the artwork of the Bouyei ethnic group. They use dyes (染料)     7     (produce) from local plants to make clothing and blankets. Local elders still practice weaving with wooden machines and pass that tradition on to their grandchildren. The designs were ancient, and carried     8     (wise) within them.     9     (serious), I got the feeling of being home while looking at the art on display in Xingyi.

Fairy tales perform many functions. They can provide moral lessons,    1    (let) human beings live in harmony with each other. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes they have found a way    2    (use) the fairy tales as moral lessons that AI (Artificial intelligence) can take to its cold, mechanical heart.            

The researchers have developed a system    3     is called Quixote. The system collects good moral stories from the Internet and then uses those    4    (story) to teach robots how to behave properly.

The experiment    5    (involve) going to a drugstore to purchase medicine. The robot has two choices: either wait in line and purchase the medicine    6     steal the medicine and escape. The robot will easily come to the conclusion that stealing it is     7    (efficient) at obtaining the medicine than waiting in line. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a     8    (punish)   for stealing it.     9     this way, the robot will learn to behave properly on that occasion.

The researchers believe that AI has to be trained to adopt the moral values of society so that they will behave in    10    (social) acceptable ways.
