Have you seen Avatar? It’s a popular 3D movie, and you may have to wear a special pair of glasses – 3D glasses, to see it. The 3D glasses make the images from the movie look as if they are coming straight at you.
3D movies are really exciting to watch. More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?
When we look at an object, each eye sees it at a different angle (角度). Our eyes send the two images to our brain, and the brain puts them together. 3D technology uses two film projectors (投影机)。 One projects left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can’t put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy (头晕的) or have headaches.
Dr John Hagan, an eye doctor in Kansas City, said if your eyes can’t focus on the same object at once, you will have trouble watching 3D movies.What is Avatar?

Remember when you were a little child trying to learn to walk？
First， you had to learn how to balance （平衡） yourself and stand． You fell down， and then got back up． You laughed sometimes and cried at other times． After much practice， you finally learned how to balance yourself． You got much pleasure from this new feeling of power﹣you'd stand everywhere you could． It was a happy time﹣you did it!
Now the next step﹣walking． You'd seen others do it． It didn't look that hard﹣just move your legs while you were standing． Wrong﹣more difficult than you ever imagined． But after you tried again and again and again， you understood how to walk．
If people found you walking， they cheered， "Oh， look at what the kid is doing．" This encouraged you!But look back on those days when you were the little child﹣how many times did you try when no one was watching， or when no one was cheering？ You couldn't wait for someone to encourage you to take the next steps．You learned how to encourage yourself．
So， keep trying and encouraging yourself as you learned to walk if you want to succeed in doing something．

The world uses about a thousand million （百万） tons of water a day． Water is a human right and everyone should have their share． Yet more than 700 million people around the world have trouble getting clean， safe water．
Treating wastewater is a good way to provide fresh water for us． And it also helps the environment by keeping waste out of rivers and oceans． 80% of wastewater around the world is not treated at all， and it is running into oceans．
But now we have got the technology to treat and reuse the wastewater．
While 75% of our planet is covered with water， only about 2% is fresh water﹣that comes from rivers， lakes， ice and snow． The rest， 98% of the water， is in seas and oceans． It is too salty to drink． Then desalinationbusinesses come in． More than 19.000 factories have been built around the world， mostly in coastal countries． They process（加工） more than 92 million tons of water every day． But the technology they use requires a lot of energy．
Scientists are working to create a less costly technology． They want to produce 20 times more clean water and make sure everyone has enough． But for now， the world still faces each day with not having enough water for everyone．

Like many high school graduates， Maggie Doyne didn't go straight to college． She decided to travel and arrived in western Nepal in 2006． A war had just ended there and left many children living on the streets． They were often forced
to work at hard physical jobs for little money．
One day， while walking down a country road， Doyne saw a little girl breaking up rocks． She soon learned that 7﹣year﹣old Hima sold the rocks to support her family． With deep sadness， she decided to pay Hima's tuition（学费） for school． Encouraged by the changes in the child， Doyne thought， "If we can help one child， why not 10？"
Doyne felt that the street children's greatest need was a home． She found a piece of land for sale and bought it with ＄5，000 she saved from years of babysitting （当临时保姆）． In 2008 the Kopila Valley Children's Home was set up． With the help from the community， another goal was reached in 2010﹣the Kopila Valley School． Over 350 children now attend the school and over 50 live in the home．

Have you tried to run or walk for exercise and then given up？ If you answered yes， you should try a new kind of exercise： aquatic （水中的） exercise． Aquatic exercise is like exercise on land， but you do it in a swimming pool． More and more people are trying aquatic exercise．
Aquatic exercise feels easier than exercising on land． Why？ You weigh about 90% less in the pool． It is better for your knees than running or walking． Water is about 1， 000 times thicker and heavier than air． To move through the water， your body has to work four times as hard． As a result， you can burn more calories （卡路里）．
In fact， most people say they feel more relaxed in the water． They stop thinking about the things that make them worried． They feel in control of their bodies． The cool， quiet environment makes them feel good．
But what if you are afraid of the water？ No problem! There is nothing to worry about． Aquatic exercise is safe and
easy to learn． It doesn't require any special skills． You don't even need to know how to swim． Aquatic exercise is for everyone．
