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.

Let’s go camping

　　What do we do when we go camp? First, we work out a plan. We take food, clothing, a knife, and things for cooking and eating. We take things to keep us away from insects and the sun.

　　Then we put everything into the car and we drive to the woods. We look for a place for campers (露营者) and we look for a good place for our tent(帐篷). The place should have a lot of moving air. This will keep some insects (虫子) away. High land with water on both sides of it is good. Then we put up our tent. We put everything into the tent, and we are ready for fun. We can swim in the lake, walk in the woods, climb a mountain, row a boat, or go fishing.

　　In the evening we come back to the tent, we build a big fire because it can keep the insects away. We sit around the fire and talk. We may tell interesting stories or we may sing songs.

　　At night we lie down on the grass. We can look up at the stars. It is a busy day, so we try to go to sleep early.

　　Everything is dark. Everything is quiet. We hope we won’t hear music from the radio in the next tent. We hope it won’t rain.
