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.

It was my first day at school. I felt nervous. I went to all my classes with no friends. I felt like no one cared.

I listened carefully to all the lessons and waited for lunch time at one o’clock. Then, finally, the bell rang. It was time to talk and have fun.

In the lunch line I met a new friend from Arabia(阿拉伯), and though I am Jewish, we got along well. I was so happy when she said, “Sit with us at our table.” She showed me the table next to the door.

So I agreed. I took my dish and was going to walk with her across the floor, when suddenly someone stopped me. “Hey, I saw you on the bus,” said a tall girl in a long skirt. “I see your Jewish star necklace(项链). You should sit with us.”

At that moment I looked around. The Spanish only sat with other Spanish, the Russians always with Russians and never the Arabs with the Jews.

I knew why wars(战争) started. Everyone sticks to(坚持) his or her own kind. The lunchroom was like a map of the world. Why was everyone so blind(盲从)?

April 22 is Earth Day. Everyone on earth should care about and protect the earth!
The earth has warmed by about 1℉ (华氏度) over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer.
　 First, greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In return, the warmth of the earth changes the climate, too.
　 When the earth becomes warmer, there may be more rain and a rise in sea level (海平面). It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one meter by 2100.
　 People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.
