How quickly can you count from one to ten? Do you use ten different words to do it? Can you do it in English, or do you have to use your first languages? Do you count on your fingers? Many people think that numbers and math are the same all over the world. But scientists have discovered that it is not true.
People in different parts of the world use different ways to count on their fingers. In the United States, people think begin counting with their first fingers, which they extend or stick out. They then extend the rest of their fingers and finally the thumb(拇指）to count to five. Then they repeat this with the other hand to get to ten. In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand.
Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. Some languages have only a few words for numbers, and others have no words for numbers. A group of scientists studied aboriginal(土著的）people in Australia. These people don’t have hand movements to stand for numbers. They don’t even have word for numbers. However, they are still able to understand different ideas about numbers.
In a similar study, researchers from the Massachusetts Institute of Technology discovered that people of the Piraha tribe(部落） in northwestern Brazil don’t have words for numbers such as “one” or “three.”. They are not able to say “five trees” or “ten trees” but can say “some trees,” “more trees,” or “many trees.” Professor Edward Gibson said that mist people believe that everyone knows how to count, “but here is a group that does not count. They could learn, but it’s not useful in their culture, so they’ve never picked it up.”
Although all humans are able to understand quantities(数量）,not all languages have numbers and not all people use counting. Number words in a certain language are a result of people needing numbers in their daily lives. Now we know that people have different ideas about numbers and math, too.

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.
小题1: Do 3D movies use special technology to make pictures?
小题2:What does Woods Company plan to do in the near future?
小题3: What can you see when you move your finger between open eyes?
小题4: How many video cameras are needed when making a 3D movie?
小题5: What is the passage mainly about?
