    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 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(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 these
people to get dizzy(头晕的) or develop 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.

1. According to the passage, Avatar is a ______.

A. digital camera

C. 3D movie

2. The 3D glasses can make the images from the movie ______.

A. 3D computers
B. 3D phones
C. 3D TV sets

4. When we look at an object, ______.

A. each eye sees the object at the same angle
B. our brain puts the two different pictures together
C. there will be two film projectors in our eyes

5. If you wear a pair of 3D glasses, ______.

A. you will see different images in both eyes

　　Roller-skating is a sport that people of all ages can enjoy. Many people like to roller-skate in an indoor rink. You can have just as much fun skating outdoors ,though.

　　If you do skate outdoors you should wear special clothes. Even the best skaters fall once in a while, but the right clothing can keep you from getting hurt. First, be sure to wear a long-sleeved shirt and long pants. Elbow (胳膊肘)and knee (膝盖)pads (垫) will help, too. A pair of leather gloves will protect (保护) your hands from getting cut on the cement. (水泥路面) Finally, a helmet (头盔), like the kind bicycle riders wear, will top off your very own “fall” fashions !
