Have you had this experience? You are watching a movie. A man is shooting on the screen. The picture is so real that you think he is shooting at you. Or a car is speeding on the screen and at one point you are afraid that it will hit you. Yes,it’s a three-dimensional(3D) movie.
　　3D movies use special technology to make pictures seem more real and exciting than two-dimensional ones.They are fun to watch, but do you know how they are made? It is much easier to understand if we do an experiment.
　　Hold one of your fingers up at arms length and close one eye. Then try closing the other eye. As you switch(切换) between open eyes, you should see your finger “jumping” left and right against the background.
　　This happens because our two eyes are about 4cm away from each other. The separation(分开) causes each eye to see the world from a different angle. The brain puts these two views together. What you see becomes three-dimensional.
　　3D movies are made using two video cameras at the same time, which creates two different images. When the movie plays in a cinema, two projectors(放映机) put the two images on the screen. With a pair of 3D glasses, the two images are separated and each image only enters one eye. Your brain puts the two pictures back together, and the pictures on the screen become three-dimensional.

So far we can only see 3D movies in the cinema with a special screen and projector. But soon, we will be able to watch them in our living rooms.

51. According to the passage,3D movies _________.

A. are less real than the common movies
　B. use special projectors to make pictures

　D. can be only seen in the cinema now

52. We need _________ when seeing a 3D movie.
　A. Fingers.　　　　　　B. 3D glasses.　　　　C. Cameras. 　　　D. Pictures.

53. From the passage, we know that 3D technology ________.
　A. works in similar way of eyes seeing things
　B. creates two different images separately
　C. uses special video cameras and screens
　D. can be very easy to experiment with
54. In which page of a newspaper can you most probably read this passage?

A. Fiction　　　　　　 B. Advertisement　　　　 C. News　　　　 D. Science
55. The passage is mainly about ________.
　A. how 3D movies develops　　　　　　　　　　　 B. what 3D movies are

     Being safe in your everyday life needs knowledge. If you remember the
following information, your life will be much safer.

alone outside. Make sure where the public phones are. If anything dangerous
happens, you can find them easily.

of putting it on your back. When a bus is full of people, it is easy enough for a
thief to take away the things in the bag on your back.

go to the other way, let the person understand that you know he or she is after

dangerous for you to be alone in your home or in lift(电梯).
