When you watch 3D movies or TV, you have to wear a special pair of glasses. The 3D glasses make the images from the screen look like they are there in the room with you.

    Three-dimensional, or 3D, means having three dimensions（维度）: width, height and depth. 3D technology（技术） is based on the way the human brain（大脑） and eyes work. Because the pupils of a person's eyes are about 6.5era apart（分开）, when we look at something, each eye sees,it from a different angle（角度）. Our eyes send the two images to our brain, and the brain puts them together. The small difference between the image from the right eye and the image from the left eye allows us to see depth.

    When we view pictures and television in two dimensions, each eye gets the same information. That is because the image has no real depth, and there is only one of viewing it. So the goal of 3D technology is to get a different image into each of the viewer. It uses two film projectors. One projects a left eye image and the other projects a right image. The 3D glasses allow us to see a different image in each eye.

    While watching 3D films, we feel that we are in the same environment as the things we're watching. However, it also has its disadvantages. The 3D glasseswork by controlling the amount of light that reaches the eyes. It makes the screen look darker. What's more, people with eye problems may get headaches if they spend too much time watching 3D movies，because their brains need to work harder to "read" the images.

    Different weather makes people feel different. It influences health, intelligence(智力) and feelings.

    In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states(州) have more heart trouble after the weather changes in February or March.

    The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ(智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).

    Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.

    Low air pressure(气压) may make people forgetful(健忘). People leave more bags on buses and in shops on low-pressure days. People feel best at a temperature of about 18℃.

    Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather's problem.

    When a man was walking along the street, he saw a woman carrying a large box. It was half in and half out of her car. So the man went up and said, "The box looks very heavy. Let me give you a hand. "

    "That's very kind of you, "the woman said, "I'm having a lot of trouble with it. Maybe it sticks（卡住）in the car door. "

    ""Together we'll soon move it," the man said. "I'll get in and take the other end." And he got in the car.

    "Right," the man said. "I'm ready," and he began to push the box hard.

    For several minutes, the man and the woman tried to move the box. Soon they felt very tired.

    They rested for a moment. Then the woman said, "Let's try again. One, two, three!" They went on moving the box At last, when they were exhausted, the man said, "I'm sorry, but I don't think there's any way to get it out of your car. "

    "Get it out?" the woman cried. "I'm trying to get it in! You know?"
