阅读下面五篇短文,根据文章的内容选择最佳答案。

  The London Olympic Games are coming soon.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 images look like they are there in the room with you.For example, while a car is running fast towards you on the screen, you are afraid that it will hit you.Yes, it's a 3-D movie.But do you know how they are made?

  3-D is based on the way the human brain and eyes work.When we look at something, each eye sees it from a different angle(角度).Our two eyes send the two images to our brain, and the brain puts them together.What you see becomes 3-D.

  3-D movies are made using two video cameras at the same time, which creates two different images at different angles.When the movie plays in a cinema, two projectors put the two images on the screen.One projects(投射)a left eye image and the other projects a right eye image.The 3-D glasses help get a different image into each eye of us.

  While watching 3-D films, we feel that we are actually in the same environment as the things we’re watching.However, it also has its disadvantages.The 3-D glasses make the screen look darker so your eyes are easy to get tired.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 images.
