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.

One week or so ago, I had hot pot with one of my     1     (colleague) after a night class. We were enjoying the delicious food and chatting happily     2     a woman approached our table.     3     (feel) bothered and interrupted by a seemingly beggar I didn’t intend to offer her a response at first, because she was so young that I believed she should work to make     4     living instead of begging.

To my surprise, she showed me a box of native incense (焚香), and was very enthusiastic     5     persuading me to buy     6    . I felt she was truly     7     (respectable) than before. She charged 50 yuan and we bargained with each other. Finally we reached an agreement     8     I could buy the incense at the price of 45 yuan.

At the instant of paying the bill on We-chat, I     9     (hesitate) and eventually typed 5 and 0 in the blank. The lady gave the incense to me politely and left. Several seconds later, she came back and thanked me     10     (constant) with a smile lightening her face. “It’s your self-dependence that matters.” I responded to her sincerely.

Tibet was a region I was desperate to see,     1     its remoteness and my inability to go delayed my journey. Last summer, my brother and I finally decided to take the trip.

We set off at the Guangzhou train station and three days later, we arrived in Lhasa. The trip certainly took a while; however, we     2     (reward) with the most beautiful views and made friends along the way, all at a     3     (low) cost than flying.

We started our tour of Lhasa watching pilgrims(朝圣者)doing their morning prayers,     4    (comprehensive) exploring the palace. We had an incredible lunch at one of the best restaurants in Lhasa,     5     offered a beautiful view overlooking the Jokhang Temple.

Then we started our journey to the Qomolangma base camp    6     road from Lhasa. Along the way we stopped     7     (admire) the Yamdrok Lake. Its beauty was beyond     8    (describe).

About a week later, we arrived. We stayed in a guesthouse just next to the base camp and after dropping off our luggage,     9     (head) straight outside to see the Mt. Qomolangma. The tip of the mountain emerged through the clouds,     10     (astonish) us with its unbelievable height. The clouds parted and we watched the sunset over the peak.
