The Lady -- Chang E In 2170 BC, the earth had ten suns circling over it, each taking its turn to brighten the earth. But one day all ten suns appeared together, making the earth too hot. The earth was saved by a hero called Hou Yi. He succeeded in shooting down nine of the suns. One day, Hou Yi stole the elixir of life from a goddess. However his beautiful wife Chang E drank it and found herself floating to the moon. Hou Yi loved his wife so much that he didn't shoot down the moon. The Man -- Wu Gang Wu Gang was a man who learned from his master. One day he asked if he could travel to some new and exciting place. The master was angry at Wu Gang's impatience , and took him to the moon, telling him that he must cut down a huge cassia tree before he could return to the earth. Though he _ day and night, the magical tree restored itself with each blow, and thus he is up there chopping still. The cake -- moon cake During the Yuan Dynasty China was ruled by the Mongolian people. Many people wanted to rebel without being discovered. The leaders of the rebellion, knowing that the Mid-Autumn Festival was drawing near, ordered people to make special cakes. Inside each moon cake was a message with the outline of the attack. On the night of the Mid-Autumn Festival, the rebels successfully attacked and overthrew the government. What followed was the establishment of the Ming Dynasty. Today, moon cakes are eaten for family reunion.

At school they can talk to their friends, but Robert and Joanna can not see their friends. They live 100,perhaps 300,miles away and like Robert and Joanna, they all go to school by radio. Mount Ebenezer is in the centre of Australia. Not many people in "The Centre", there are no schools with desks and blackboards and no teachers in "The Centre". School is a room at home with a two-way radio. When all students answer, lessons begin. Think of your teacher 300 miles away!

input: Please answer the following: Write a multi-choice question for the following article: Article: When discussing about friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share. When I was in the eighth grade, I had a friend. We were shy and "too serious" about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:" Let's start with a train whistle today." We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped. When I lived for a time in London, I had a friend. He was in despair and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted . We gave London to each other. For almost four years I have had a remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other's dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think: "Yes, I must tell...." We have never met. It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist , who will only fill up the healing silence necessary to those darkest moments in which I would rather be my own best friend.

Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted. Though some of these things may seem impossible, they're closer to reality than you might think. The world of 3-D printing is coming to a store near you soon. The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD(computer aided design)file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want. There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs , we can soon be living longer thanks to 3-D printed technology. Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 (767,594 yuan) developing a "3-D pizza printer". It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless.
