Article: Testing new drugs for safety and effectiveness is a costly process in the United States. It also can take:lot of time. Some scientists are now designing silicon computer chips that act like human organs. The scientists think they have found a way to make the process faster and more economical. The silicon computer chips are smaller than a child's hand. Each one has living cells that act and react like a human organ. The chips are being created as part of a program to test the safety of drug compounds. It is called the Tissue Chip for Drug Screening Program. It is a project of the US National Center for Advancing Tmnslational Sciences, or NCATS. Danilo Tagle is the center's Associate Director. He says a three-dimensional computer chip can be designed to act like a human lung. Some computer chips contain very small models of the human digestive system. They copy the real function or duties of the human stomach and intestine , moving when breaking down food. Drugs are added to the tiny organs for testing through instruments known as micro-tubes. Experiments with the tissue chips have produced more detailed information than tests using animal or cell models. NCATS just announced$17 million in grants to develop an entire human organ system over the next three years. Question: What can we know about the silicon computer chip? Yes or no, is the answer ".Cells in it can act like human organs"?
Yes

Article: The story I would like to tell happened about a year ago. I accepted a position in a company. John, an acquaintance of mine, told me much about the job and took my curriculum vitae to his supervisor. I did not refer to him as a friend because at the time we did not take part in activities together outside of work, nor did our wives. The first week was fine. Nothing was obviously strange with John at first until the second week, when our communication began to get a little strange. John began making comments like "you would have had to pay an employment agency several hundred dollars for a job like this". I soon forgot his words till the next day when he made another similar comment. Right then I started to really pay attention to what he meant. He acted as if I owed him money for helping me to get the job. He began to get short with me and I had only been there for two weeks. He was supposed to train me in building our e-mail servers and setting up the entire standard monitor software. Instead, he went through the process so fast that even an experienced worker could hardly keep up. He would not slow down or check whether I was with him or not. If there was something wrong with a server, he would just buzz through the solution and not stop to say anything like "you might want to remember this." I began to get very frustrated. By the third week I began to get tired of his condescension . So I began to challenge him in a way that was only one to one. He would respond to a question of mine with a question or just make me repeat it, and then interrupt me. I began to hate him. Later I tried to avoid him as much as I could, so I wouldn't run into him. He stopped me one day and asked me what had happened. I told him he was very condescending in his tone and manner. He asked me, "What can I do so that you will not feel like this way in the future?" I simply asked him to treat me with the same respect he would like to be treated with. He did it and we got along better gradually. I believed there was hope and... Question: What's the author's purpose of sharing his story? Yes or no, is the answer "To stress the importance of communication between colleagues."?
Yes

Q: Article: A safari park is a park in which wild animals are kept. They are mainly located in east or central Africa. They often occupy a very wild area, with mountains and rivers. To visit the park and look at the animals, people have to drive around in a car for a few of hours because the park is huge. In south Africa there is a safari park, which contains all sorts of wild animals like lions, elephants, rhinoceroses, zebras, wild pigs, deer and giraffes. There is a wild road leading through the park, but nobody is permitted to walk on the road. Anyone traveling in the park has to go in a car because wild animals may fiercely attack people. From the car he may see almost every types of African wildlife. Some of these are getting rare because people kill them for various reasons. For example, rhinoceroses are killed for their horns, which are used in traditional Chinese medicines for colds and headaches. Perhaps they will be seen only in museums and books one day. Travels may purchase food for the animals. They can feed them when they tour the park. Of course, they should not feed them in a close distance because the wild animals may attack people. In addition, they should only give proper food to the animals. A traveler may carry a gun with him in his journey. The gun is given to him by the government. However, it is not used for hunting. In fact, a seal is fixed to it. The traveler may fire at a wild beast to defend himself in case he is attacked. However, he has to prove to the government that he has been attacked and that he has not fired at a harmless animal. Question: The government knows whether the gun is fired by the traveler or not by _ . Yes or no, is the answer "checking the seal"?

At first, it is not easy to feel these things. You are too used to them! Most museums are just for looking. But today some museums have some things to touch. There you can feel everything on show.
