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.

小题5:If you wear a pair of 3D glasses, .| A．you will see different images in both eyes | | B．you will see the same images in both eyes | | C．your brain can’t work at all | | D．the images can be put together easily by your brain |

Space vegetables are grown from seeds (种子) that have been taken to space and brought back to the earth. The seeds are affected by the radiation (辐射) and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy.
Here are some facts that you should know about space vegetables.
Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat.
Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.
After genetically modified (转基因) food appeared in the market, people worried that they were eating unknown things. For example, if nut genes (坚果基因) are put inside potatoes, people allergic (过敏的) to nuts might get sick from eating these potatoes because they do not know they are also eating nuts.
