听力原文：W: Are you all prepared for your Speech Club introduction this evening？
M: Yeah, I'm going to talk about robots.
W: Robots？ You mean, those machines that walk and talk like in the movies？
M: No, industrial robots, like those used in auto and electronic industries.
W: Come to think of it, I saw an article about that kind of robot the other day. There were pictures of robots joining cars, but they certainly didn't look the way I thought robot should look.
M: The robots we usually imagine are made up in science fictions. In industry robots are designed to do a specific set of operations, such as joining car frames. They are rarely built to resemble humans.
W: Actually, all they need is a kind of brain to give signals, and a mechanical appliance such as an arm to carry out instructions, right？
M: Right ! Tiny computers become the brains of these robots. The computers send signals in the form. of electrical signals that move an arm and something like our fingers. Those fingers do particular kinds of work.
W: OK. But we have had machines on the assembly line doing work for people for years. That's what started the Industrial Revolution, remember？
M: But each of those machines can only perform. a single operation and it takes months to modify them. The new industrial robots can do a number of tasks and it's easy to reprogram them to perform. totally different operations. That's one reason why they're becoming so popular.
W: They increase productivity too, don't they？ Even though they are still quite expensive, I imagine robots will be used more and more.
M: Exactly. So now that you know all about the next Industrial Revolution. You don't have to come to Speech Club tonight.

Why are actions being taken by various governments on video games？
What can we learn from the passage？
听力原文： In some countries video games are fast becoming a social problem. They are prohibited in the Philippines and Indonesia. In Japan, those who are under 15 years old are forbidden to use the public machines at night. City elders across the United States are campaigning to restrict their numbers, while the Hong Kong government is proposing to license their operation. These video games are causing children to waste their money on them. Even adults are tempted to spend working hours playing them.
In Singapore, the battle of man against the machines takes place in licensed amusement centers, mostly located in shopping centers. According to one estimate, each establishment can make between $ 250 and $ 1,500 a day. The schoolchildren in uniforms are not allowed into these centers. However, one cannot help noticing that the majority of those who are often found in these places are youngsters. Many of them are schoolchildren who have changed out of their uniforms. Some play for the fun of it; others have turned them into a form. of gambling, and some are hopelessly addicted to them.
Now kids and adults alike play these games in the privacy of their homes. Video game sets have invaded most homes. The question that must be asked is: Have they any educational value？
In which parts of the world are video games forbidden？
