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.

Dear Diary,
What a strange day! First, I saw a dog on the way to school. OK, that's not so strange. But the dog
was wearing a hat and a pair of sunglasses. And someone was feeding him ice cream. Then, the guy
took a bite of the ice cream himself. How disgusting (恶心的)!
At school, classes were pretty much the same as usual. We watched a movie in history class. It was
about World War II. The photographers were very brave. They took pictures during the fighting! I don't
think I would do that.
In the hallway on the first floor, I saw the most amazing thing. A girl was dressed in a really expensive
dress. She wore diamond earrings, and her makeup looked great. I thought she was the president's
daughter! Can you believe it? It was Cecilia Dryer! I almost fainted. She never looks so good. Of course,
I could look that good if I wanted to.
Well, that's about all. I hope my mom will let me borrow her earrings tomorrow...

It's a popular movie this year. It is three-dimensional (3D), so you may have to wear a special pair of
glasses to see it. The 3D glasses make the images (图像) from the movie look like they are coming straight
at 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. Three-dimensional technology can make TV and movies more exciting. But 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. That' show we see depth.
Three-dimensional 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.
There are a lot of people walking around with very small eye problems, for example an eye muscle
imbalance. Under normal situations, the brain can get used to their eyes so they can see things normally.
But when they are watching a 3D movie, the images projected to their eyes can't be put together by their
brain.
So the brain needs to work harder at "reading" the images. That makes it easier for these people to get
dizzy or develop headaches.
Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot
see in 3D at all. He said people whose eyes can' t focus on (聚焦) the same object at once will have trouble
seeing 3D images.
B. our brain will put the different objects together
C. our eyes will focus on the same object easily
D. our eyes will see an object at the same angle
B. When people have no eye problems.
C. When people don't have a headache.
D. When people aren't seeing a 3D movie.
B. Not all the people can watch 3D images.
C. The 3D glasses make the movie seem alive.
D. The 3D movies will be very popular soon.
