The London Olympic Games are coming soon. This summer, Chinese sports fans will be able to watch the exciting games in 3-D on CCTV.
When you watch 3-D movies or TV, you have to wear a special pair of glasses. The 3-D glasses make the people and the things on the screen look like they are in the room with you.
3-D, means having three *dimensions: *width, height and *depth. 3-D technology is based on the way the human brain and eye work. Because the *pupils of a person’s eyes are about 6.5cm apart, when we look at something, each eye sees it from different *angle. Our eyes send the two pictures to our brain, and the brain puts them together. The small difference between the picture from the right eye and the picture from the left eye make us see depth.
While watching 2-D films, we don’t have to wear the special glasses. We see the pictures in two dimensions, each eye get the same information. This is because there is only one way of watching it.
So the aim of 3-D technology is to get a different picture into each eye of the person. It uses two film *projectors. One *projects a left eye picture and the other projects a right eye picture. When we are in the cinema, we can see different pictures in each eye at the same time with the help of the 3-D glasses.
While watching 3-D films, we feel that we are actually in the same environment as the things we are watching. However, some people are against watching 3-D films. One of the reasons is the 3-D glasses makes the screen of the film or TV look darker. It is bad for eyes. What’s more, people with eye problems may get headaches if they spend too much time watching 3-D movies, because their brains need to work harder to “read” the pictures.

WHETHER you like it or not, your parents are responsible (负责任的) for you, at least until you’re out of school. Does it feel like your parents are stressing you out with their love? Do you often fight with them?
Hu Muqing, 16, of Shenyang, complains that his parents are only concerned about his grades and not his other needs. He and his parents fight the most about the time he spends watching TV and on the Internet. The Shenyang teenager said, “They think because I’m in middle school I should concentrate on my work. However, I need to be able to relax. Most of my friends can watch TV and surf the Web a lot. Sometimes it’s hard to talk to them.”
After some negotiations (商谈), Hu has been allowed to watch TV for 15 to 20 minutes every night, but has been told to keep away from the computer.
Shen Ying, 17, Jianyang, Sichuan Province. Since she feels she’s grown up now, she wants more respect from her parents. “My father shouted at me when he’s in a bad mood. He doesn’t listen to me, but instead acts like, ‘I’m the boss’!” said the teenager “I’d like my parents to treat me like a friend and understand that respect is a two-way street.”
Lu Yiting, 15, of Shantou, has a different problem with her parents. They think she spends too much time with her friends and is falling into bad company. “I want trust from my parents,” Lu said.
It’s the age when teenagers are becoming more independent (独立的), but their parents are very concerned about their kids’ futures, said Sun Yunxiao, a senior researcher at the China Youth and Children Research Center. Sun suggests that teenagers should learn to communicate with their parents effectively. “Find the right time for a talk. On Mother’s Day or Father’s Day, say ‘Thank you’ to your parents or give them a small gift with a letter so they can get inside your head a little,” he advised. Sun also believes that teenagers have to work to earn trust and respect from their parents. “You need to make sure they know that you’re not going to screw up (搞砸) your exams or let them down. Let them know that you want to do well, and that you will do well,” he said.
