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.

March 16 is World Sleep Day. This year’s slogan is “Breathe Easily, Sleep Well”. Its aim is to celebrate the *benefits of good and healthy sleep.
Fangfang, from Liaoning, just became a high school student last September. She gets up at 5:30 a.m. every day and goes to bed at about midnight. Fangfang feels sleepy all the time. “I want to finish all my homework first,” she said.
Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep *Foundation in the US, adults need seven to nine hours of sleep every night. For students who are 10 to 17 years old, a healthy amount is about eight to nine hours every night.
But many students don’t get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others,they may even have insomnia, and usually they have to ask the doctors for help.
These sleeping problems greatly *affect people’s life. Some doctors found out that *lack of sleep for teenagers lead to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, they often become anxious easily.
Luckily, with good sleep habits, it is easier to fall asleep. Some of these good habits include *avoiding drinks that make people excited late in the day, going to sleep at the same time every night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.
More tips to get a good night’s sleep:
Exercising during the day. You’d better do sports three hours before going to bed.
Don’t eat big meals before bedtime. Drink a warm glass of milk.
If you stay awake worrying about things, try making a list of things that you need to do before you go to bed.

“Jason, honey? Can you answer the door?”
“I am busy, mom！” Jason shouted back at his mother. He had spent three hours so far working to this point in the game. He couldn’t stop now.
Ding-Dong！Mom′s footsteps approached the front door.
“Jason, it’s your friend Todd.” Mom called from the doorway.
Todd, his best friend, stepped into the room. “ Jason！I need a partner for playing basketball. ”He sounded excited.
Jason snorted. “No way, Todd. I′m playing a game here.”
Jason gave his friend a dirty look, and his character in the game almost got killed while he looked away, “ I almost died because of you！”
Todd looked at Jason′s mother. Jason’s mother looked back at him. They both looked at Jason. “Why don′t you play basketball with your friend?” Jason’s mother suggested.
“Tomorrow, maybe…” There were more levels to beat tomorrow, though, Maybe he had played tomorrow. He’d have to see what mood he was in. He thought he heard footsteps walking away, but he was too busy beating the next level to care.
An hour later, Jason’s father came home. It was dinner time after his father washed up and sat down. Jason didn′t even hear his name being called to the table. He didn′t hear his father walk at behind him and ask him to turn the game off, either.
When the screen suddenly went black and his father’s angry face loomed in front of him, Jason finally heard. “No more game for a month.” Jason′s father shouted at him. “You don’t play basketball, you don′t come to dinner, and you don′t do your chores. We′ll make you do something else before you play any more.”
Jason nodded slowly. He knew better than to argue with his father, and when he thought about it, he had been playing quite a bit. It was fun, but he was letting down his friends, his family, and himself by paying too much.
He′d try harder in the future.

| A．Inside the game | B．Games or Supper. |
| C．Jason′s Angry Father | D．Use of the Computer. |
First, the population is growing very fast. There 2 more and more people in the world and most of them will live longer than before. Computers will be 3 smaller and more useful, and there will be 4 one in every home. And 5 studies will be one of the most important subjects in schools.
Second, people will work 6 hours than they are doing in the 21st century. They’ll have more free time for sports, watching TV and7 . Traveling will also be cheaper and easier. And more people will go to8 countries for holidays.
Third, there will be changes in our food, too. People will use more land to 9 new towns and houses. Then there will be less room for cows and sheep, so 10 will be more expensive. Maybe no one eat it everyday; 11 , they will eat more vegetables and fruit. Maybe people will be 12 .
Last, work in the future will be13 , too. Robots will do the 14 and hard work. Because of this, many people won’t have 15 work to do. This will be a problem.

The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine， too. They are really good places for wildlife（野生生物）。 Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily， more and more people are beginning to realize the important of wetlands and wildlife. Every year， on February 2nd， many activities are held to tell people more about wetlands.
