Have you had this experience? You are watching a movie. A man is shooting(射击) on the screen. The picture is so real that you think he is shooting at you.
Three-dimensional(3D)movies use special technology to make pictures seem more real and exciting than two-dimensional ones.
So far we can only see 3D movies in the cinema with a special screen and projector(放映机）. But soon, we will be able to watch them in our living rooms. Last month, Woods Company told reporters that it plans to bring 3D televisions to homes in the near future.
“The 3D train is on the track, and we are ready to drive it home,” said the President. 3D movies and TV programs 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 arm’s length and close one eye. Then try closing the other eye. As you move between open eyes, you should see your finger “jumping” left and right against the background.
This happens because our two eyes are about 4 cm away from each other. The separation causes each eye to see the world from a different angle(角度). 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（影像）. When the movie plays in a cinema, two projectors 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.
1. Do 3D movies use special technology to make pictures?
2. What does Woods Company plan to do in the near future?
3. What can you see when you move your finger between open eyes?
4. How many video cameras are needed when making a 3D movie?
5. What is the passage mainly about?

Are you carrying too much on your back at school? I’m sure lots of children of your age will say “yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.
“It’s hard for me to go upstairs with my bag because it’s so heavy,’said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps to carry them, but many other students choose rolling bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight.
Scott Butch, a back doctor, said children under Grade 4 should stay with 10%, but it is also important that older children don’t stay with over 15%, because their bodies are still growing. “Children are losing their balance and falling down with their school bags,:” he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin work books for students to take home.
One of the best answers is, as some children said, to have no homework at all!

A. only children in China carry too heavy school bags

It was a cold day, but the students from Prosser Middle School in Chicago were sorting through the waste when they found that their school produces 1,500 pounds every day.

food tray
“None of the trays are being recycled,” said a teacher. “ Everyone agrees that it’s very bad.”
Luckily, concerns about the environment and health have made some US cities take action. Dozens of schools have begun programs to reduce the use of food trays in school.
These schools have also banned (禁止)some fast food, including McDonald’s. Instead, they offer students recyclable trays. They encourage students to sort out lunchroom waste, then wash and recycle milk cartons and trays . So far, the program has helped schools to save a total of 820,000 trays each week.
Jay Stream Middle School in Illinois teaches its students how to collect trays. The school has cut its lunchroom waste by two thirds now that students recycle their used trays instead of breaking them.
Prosser Middle School also sees the benefits of the program. Students have organized about 20 clubs and volunteer activities to cut down on cafeteria garbage. They now recycle 80 percent of the school waste. “ I joined the club,” said Erika Santana, a 16-year-old junior in Prosser, “because I want to make Earth a better place.”
1.Did Prosser Middle School create much garbage every day before the program ?
2.How many meal trays do public schools in Chicago throw out a day?
3. What does Jay Stream Middle School teach its students to do?
4. Who joined the club?
