*Question*
Once again, I had run away and really did not know why. I walked out of the gate to go to school and then kept walking, and walking, and walking. I was 11years old. It was almost dark; I was tired, cold, and all alone. I had not eaten all day and was afraid to turn myself over the police. I knew I would receive another beating once I returned to the Children's Home Society. There was nothing for me to do, except keep on walking. As darkness fell, I entered the darkened area in a city park sat down on a wooden bench hoping to avoid the police cars. It was cold and I began to tremble uncontrollably. All was quiet except for the passing cars in the distance. "Well, hello young man." A voice came from behind me. I jumped, almost falling off the park bench. My heart was beating ninety miles per hour. I gasped and I could hardly catch my breath. I looked up and saw a woman standing behind me in the shadows. "You look cold and hungry," she said. She took off her scarf, wrapped it around my shoulders and asked me to follow her. We walked about twenty feet, and then stopped under one of the park streetlights. She held out her hand and said, "Here, you take this letter." Seeing nothing in her hand., I stood still. "Reach out and take the letter from my hand," she insisted. Slowly I reached out, acting as though I was taking something from her hand. "Now hold the paper tightly and take it to any store owner," she instructed. I closed my thumb and finger as though I were grasping the letter and began walking toward Five Points. Several blocks down the road, I came to a store with a woman sitting behind a counter. I opened the door, walked in, and stopped directly in front of her. Very slowly I held out my hand toward her. I watched her face to see if she might think I was crazy or something. She reached out and as her hand touched mine, I opened my tightly closed fingers and stood there waiting. She pulled back, smiled, and looked down at her hands. She immediately turned and walked to the back of the store. After a... What can we learn about the boy? A) Though lost in the city, he didn't feel worried or lonely. B) He had nowhere to go and wandered aimlessly in the street. C) He avoided the police for the fear that he would be sent to prison. D) He had to run away because of his bad performance at school.

The most complex object known to humanity is the human brain -- and not only is it complex, but it is one of the few natural phenomena that science has no consciousness of. To try to replicate   something that is so poorly understood may therefore seem like pride. But you have to start somewhere, and International Business Machines (IBM) and the Ecole Polytechnique Federale de Lausanne (EPFL), in Switzerland, propose to start by replicating "in silico", one of the brain's building blocks. In a partnership announced, the two organizations said they would be working together to build a simulation   of a structure known as a neo-cortical column on a type of IBM supercomputer that is currently used to study the molecular functioning of genes. If that works, they plan to use more powerful computers to link such simulated columns together into something that mimics  a brain. In a real brain, a neo-cortical column is a cylindrical element about a third of a millimeter in diameter and three millimeters long. It is these columns, arranged side by side like the cells of a honeycomb, which make up the famous "grey matter" that has become shorthand for human intelligence. The Blue Gene/L supercomputer that will be used for the simulation consists of enough independent processors for each to be programmed to mimic an individual nerve cell in a column. The EPFL's contribution to the Blue Brain Project will be to create a digital description of how the columns behave. The database from its Brain Mind Institute will provide the raw material for the simulation. Biologists and computer scientists will then connect the artificial nerve cells up in a way that mimics nature. They will do so by assigning electrical properties to them, and telling them how to communicate with each other and how they should modify their connections with one another depending on their activity. That will be no mean feat. Even a single nerve cell is complicated, not least because each one has about 10,000 connections with others. And nerve cells come... In a real brain, a neo-cortical column   _  . A) looks like the cells of a honeycomb B) is a simulation of a structure C) is the famous "grey matter" D) contains a large number of nerve cells

There are thousands of things to be sold that are of all colors and shapes in a supermarket, making you believe that they are good enough for you to have a try. How packaging is the quiet but persuading salesman? There on the shelves,each bottle, can and box has been carefully designed to speak to the inner self of the consumer , so that he is buying not only a product but also his belief in life. Scientists have studied on this and found that the look of the package has a great influence on the "quality" of the product and on how well it sells, because "Consumers generally cannot tell between a product and its package. Many products are packages and many packages are products," as Louis Cheskin, the first social scientist studying consumers' feeling for packaging, noticed. Colors are one of the best tools in packaging. Studies of eye movement have shown that colors draw human attention quickly. Take V8 for example. For many years,the bright red color of tomatoes and carrots on the thin bottle makes you feel that it's very good for your body. _  Shapes are another attraction.Circles often mean happiness, because they are pleasing to both the eye and the heart. That's why the round yellow M sings of McDonald's are inviting to both young and old. This new consumer response to the colors and shapes of packages reminds producers and sellers that people buy to meet the needs of both body and heart. What's the best title of the passage? A) Colors and Shapes B) Packaging Can Talk C) The response to the packages D) What is packing?

In Shanxi Province you may be offered brains to eat. Frightened? You shouldn't be because these brains are only a food, which is famous for its unusual name and rich nutrition .  Brains as a food were invented more than 300 years ago by Fu Shan, an artist whose mother had been ill for a long time. To help her become well, he studied medicine and invented a kind of soup made of meat, vegetables and a number of Chinese medicines. Rice Wine was also used in the soup to cure illnesses caused by old age. After taking the soup his mother got better little by little and lived a long life.  Fu's soup became the talk of the town. Many people came to see him. One day a restaurant owner asked him what was in the soup. "I'll tell you, " Fu said, "but if your restaurant is going to sell the soup, you must call it brains because of its shape and colour. And your restaurant should be renamed after my mother. " Before Fu told the restaurant owner what was in the food, he demanded that   _  . A) the restaurant shouldn't offer any other food B) the restaurant should use his mother's name C) the shape of the food should never be changed D) the food should be used to help sick people
