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.

Want a good night's sleep? Then turn off your computer, cell phone or PSP two hours before you go to bed.

These things have bright lights. When our eyes see bright lights just before sleep, our sleep patterns (模式) change, a study has found.

Our body clock starts shutting us down for bed at 9 or 10 pm. But bright lights make our minds think that it is still daytime. That wakes us up and leaves us sleepless, experts say.

    But if you read a paper book before sleeping, you won't have this problem. This is because light from a bedside lamp (台灯) does not go straight into our eyes.

    Also, if you are watching a television from across the bedroom, you won't have problems falling asleep. The TV sends light to us from a distance, so the light won't be as strong.

1.The writer tells us to turn off the computer          before bed time.

    A. half an hour     B. an hour        C. two hours       D. three hours

2.Which of the following may make us sleepless?

    A. Reading a newspaper.                 B. Talking on QQ.

    C. Reading a book.                      D. Watching TV.

3.Why can't we sleep well if we use a computer before bed time?

    A. We think it is daytime if we leave computers on.

    B. We feel too excited to sleep after using computers.

    C. Lights from computers are brighter than other lights.

    D. Lights from computers can change our sleep patterns.

 

For hundreds Of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
