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.

Americans love sports . But this hobby sometimes has serious results—at least to the players. For example, when people play tennis, sometimes they hurt their elbow（肘部）. Also it is easy to hurt a knee in a football game. These injuries（毁伤）happen while the player is having fun, but they still hurt.
A few months ago, Kathleen Simmons, who loves playing volleyball, hurt her knee in a volleyball game. Her doctor told her that she needed a very difficult operation（手术）or she might not be able to play again. She felt very sad
Then Simmons learned about “video operation”. With the help of this new science in medicine, doctors can now repair many injuries.
For this operation, her doctor didn’t have to open her knee. Instead he put a very small camera lens（镜头）inside her knee. The lens sent back pictures, which appeared on a television screen. As he worked, he could see the inside of her knee on the TV. With the help of the large pictures on the screen, the doctor knew exactly what to do when he was making the repairs.
Simmons started walking five days after her operation. “My knee hurt a lot the first few days,” she said. “But I felt better very quickly.” Now, six months after her operation, Simmons can do everything she did before her injury. “It feels like a new knee,” she said. “I can even play volleyball again.”

It’s Tuesday afternoon, and I’m in Rheinburg, Germany, visiting the Extra Future Store. The “store of the future” is attracting a lot of attention these days– but not for it’s prices. Instead, people are coming from all over to experience a new way to shop.

   The experience is less like shopping in a supermarket and more like playing some kind of high–tech game. It starts as I enter the store and choose a shopping cart(购物车). First, I swipe my store ID card through a computer on the cart. The computer’s screen comes on, a map of the store shows, and the journey begins.

   As I shop, antennas(天线) around the store send information about different specials to the computer on my cart. Attracted by one of the ads, I choose a box of cheese. I hold up the box to the computer. It displays the price and also suggests that a certain type of bread would be good with it. The map on my chart shows me where to find the bread. It’s like the store is helping me to shop.

   How does the store make this kind of shopping experience possible? The answer is radio frequency identification chip (or RFID射频识别). Each chip has a special number. Using an RFID reader on the computer, we can get information from a chip about the product(产品). RFID will help shoppers find the things in a store more quickly– products that are just right for them. In addition, people won’t have to wait in long lines to pay. The things in your cart will be read by the computer and the money will be paid by your store ID card automatically(自动地). So you can simply walk out of the store with your shopping bags.

  Sounds good, right? Maybe you will experience the new shopping soon in your city.

A. They hope to buy a new kind of computers.

B. They want to play some new high– tech games.

C. They expect to experience a new way of shopping.

D. They plan to learn how to use the FRID readers.

2.What is the right order to shop in this store?
