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.

Teens want structure in their lives, which means they want their lives well-planned. To begin building structure, teens need love and trust. They need to know their parents arc there to give them needed love and support (支持).Teens want to be sure that nothing can prevent parents from shouldering their responsibility for them — not their growing maturity (成熟),misbehavior, nor anger at something they have done. Teens want parents to keep control while allowing them to make some decisions.
There are some ways you can help your teens create reasonable structure and remain close. One way is to spend time together. Parents often mistake their teens’ increased interest in friends for a disinterest in the family.
Teens would like to spend more time doing things with their parents, but watching TV is not counted as spending time together. As your teens mature, it is important for you and your teens spend time alone together, one to one. Your teens need time to talk to you alone without any other family member present.
Talk with your teens about their interests and concerns. Make sure you really show interest in what is happening. When talking with your teens, give full attention and do not stop them.
The way to help your teens become adults is to let your teens into your world. Sharing your emotions and concerns with your teens is important. Avoid causing needless worry.
Trust your teens. Don't expect the worst. Hope for the best. Telling your teens you don’t like their friends will cause the teens not to bring their friends home. If something should go wrong, believe that your teens didn’t do it on purpose.
It is very important that you treat your teens with respect. Teens need the same respect adults show for total strangers. Don’t talk down to your teens.
You need to be supportive o f your teens. What may be a small problem to you may be troubling to your teens. Teens don't have the experiences that adults have had. Let the teens know that you understand how much it hurts when something happens that is upsetting or hurtful to them. As they mature, they can look back at some problems they had and laugh at having been upset by something that now seems unimportant.
The most important things to remember are: talk with your teens, listen to their worries and offer suggestions when needed. This will help your teens to live a well-organized life.

Have you ever wondered what goes through your mind when you choose where to sit in a new classroom? Or in a waiting room full of strangers? Or on a bus? Researchers have found out some interesting facts.
Perhaps unsurprisingly, we prefer to sit closer to people like ourselves. Girls sit by girls and boys sit by boys. Adults sit together and young people choose another young person to sit near. But it goes further than this. We even choose to sit near someone who looks like us. People with glasses are more likely to sit near other people with glasses. People with long hair sit closer to other people with long hair.
We seem to believe that people with similar habits or hobbies will share similar attitude and we are more likely to be accepted by people like ourselves or even, we think we may be safer with people who look like us. Sometimes that’s true but it's a pity if we always stick to the same people, the same group. The danger in always staying in our comfort zone (舒适区)is that we just recycle the same opinions, the same tastes and the same ideas. We lose the chance to learn something new, find out about interesting things, hear funny stories and discover difference.

When we always stick to the same people, how can we ever break down the barriers which prevent us from getting to know people with different ideas? And how can we avoid the ignorance (无知),which too often leads to prejudice (偏见) and even fear? If instead you want to live in a society that opens to changes and new things and different opinions, be the cat among the pigeons.
Move out of your comfort zone. Go and sit next to someone different. And don't just sit there in silence. Say hello. Ask a question. Start a conversation. That’s how we make friends. That’s how we learn about people. That’s how we open our minds to new ideas. That's how we live an exciting life.
