      Have you seen Avatar（《阿凡达》）? It's a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images(图像)from the movie look as if they were coming straight towards you. 

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 are 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(物体), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大脑), and the brain puts them together. 3D technology uses two film projectors(投影机). One projects a 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. A famous eye doctor said if your eyes can't focus(聚焦) on the same object at once, you will have trouble watching 3D movies.

The key to learning a new skill isn't necessarily how many hours you spend practising, but the way you practise. Scientists have found that by simply changing your training method, you can keep your 1 more active in the learning process and spend less time reaching the required standard. People think simply 2 a skill—for example, practising the same piece of music on the piano or playing the same level in your game over and over again—is the best way to learn it. Instead, it turns out that there might be a 3 way to level up. 

Recently, researchers got 86 volunteers to learn a new 4 —moving a cursor(光标) on a computer screen by pressing a small device, 5 using a mouse. The volunteers were divided into three groups, and 6 spent 45 minutes practising the skill. Six hours later, one of the groups was asked to repeat the same training exercise again, 7 another group to perform a different version(版本) that required a different pressing8 to move the cursor. The third group was 9 asked to complete the first training, acting as a control(对照组). 

In the end, everyone was 10 on how they could perform the new skill. As a result, the group that had repeated the original(原来的) training did 11 on the test compared to the one that had had mixed training and trained in new areas—in fact, the group that had 12 their training method did twice as well as the group that had repeated the original training. 

So how does that work? The researchers believe it's due to something called reconsolidation(重新合并), which is a process: 13 are recalled and changed with new knowledge. "Our results are important 14 little was known before about how reconsolidation works in relation to skill development. This shows simple training method changes can 15 more rapid and better skill gains, " said Celnik. 

Staying on a plane for long hours can be hard. You may think about watching a film to kill time. There are many interesting things you can do.

Listen to a podcast (播客)

{#blank#}1{#/blank#} You can listen to podcasts. Podcasts are like radio shows. There are comedy podcasts, educational podcasts, news podcasts and so on. You can always find something you are interested in.

Take pictures

Keep a diary

Did you forget something when you tried to tell your friends about a fun trip? If your answer is yes, you can keep a diary. {#blank#}3{#/blank#} When you're back home, you can share your diary online and tell more people about your fun trip.

Learn something new
