阅读理解

    When you watch 3D movies or TV, you have to wear a special pair of glasses. The 3D glasses make the images from the screen look like they are there in the room with you.

    Three-dimensional, or 3D, means having three dimensions(维度): width, height and depth. 3D technology(技术) is based on the way the human brain(大脑) and eyes work. Because the pupils of a person's eyes are about 6.5era apart(分开), when we look at something, each eye sees,it from a different angle(角度). Our eyes send the two images to our brain, and the brain puts them together. The small difference between the image from the right eye and the image from the left eye allows us to see depth.

    When we view pictures and television in two dimensions, each eye gets the same information. That is because the image has no real depth, and there is only one of viewing it. So the goal of 3D technology is to get a different image into each of the viewer. It uses two film projectors. One projects a left eye image and the other projects a right image. The 3D glasses allow us to see a different image in each eye.

    While watching 3D films, we feel that we are in the same environment as the things we're watching. However, it also has its disadvantages. The 3D glasseswork by controlling the amount of light that reaches the eyes. It makes the screen look darker. What's more, people with eye problems may get headaches if they spend too much time watching 3D movies,because their brains need to work harder to "read" the images.

举一反三
   1990 was a significant year in world enents. In Febbruary, Nelson Mandela was set free after 27 years in prison. In October, East and West Germany became one country again. Then at the end of 1990, the World Wide Web was born. For this final event we have one man to thank, Tim Berners-Lee, the father of the Web.
   Berners-Lee was born on June 8, 1955 in London, England. His parents, both computer designers, encouraged him to think and work creativelhy as he grew up. He was an excellent student and naturally took an interest in computers and science.
   After graduating from Oxford University, Tim went to work at a science research centre in Sfwitzerland. There be developed some of the different systems that would later become the Web. The first was HTML, the computer language used to make web pages. The second was an address system that let  computers anhywhere find each other and send and receive information. In 1990, while still at the science centre in Switzerland, he put them together to make the first Internet browser. It could run on any computer and allowed people to create  share their information with the rest of the world.
   Tim knew that the more people used the Web, the more useful it would be. He wasn't interested in money but knowledge, so he gave out his invention for free to anyone who was interested. Many were interested and the growth of the Internet began.
   Today Tim works as a professor at the MIT in America, researching new and interesting ways to use the Web. He has received many awards from governments and organizations for his efforts. He is still not very interested in money. That is why he is so admired by his students and workmates. It may also be one of the reasons that few people outside the world of technology know his name.
