Teleportation is a combination of sending information through telephones or the Internet and transportation. With normal transportation, for example by car or plane, a person or thing is moved from point A to point B. With teleportation, a person or thing is taken apart at point A and put together again at point B. If teleportation becomes possible, we may be able to travel faster and farther than we could ever imagine. In the 1990s, scientists discovered that teleportation was possible. Experiments showed that teleportation could be done, but the thing being teleported was destroyed on the way. So far, scientists have only been able to teleport photons—particles(粒子) hat carry light—and laser beams(激光).What about teleportation of human beings? Teleporting a human being would be very difficult since there are so many parts in a human body. Even the smallest mistake could cause serious problems with the person’s mind or body. There is still a long way from being able to use teleportation to move human beings, but what we used to think was impossible does now seem possible. What we know and what we imagine often work together :the more we know, the more we can imagine, and the more we imagine, the more we can learn. Science is the tool that we use to make our dreams become real and to build a new world with our ideas. Ⅳ.Teaching Time: Four periods The First Period Teaching Aims: 1.
