听力原文:W: Hi, Paul, are you ready for your Speech Club presentation this evening?
M: Yeah, I'm going to discuss robots.
W: Robots? You mean those machines that walk and talk like in the movies?
M: No, industrial robots like those used in the automobile and electronic industries.
W: I saw an article about that kind of robots the other day. There were pictures of robots welding cars, but they certainly didn't look the way I thought robots should look.
M: The robots we usually imagine are made up in science fiction. In industry, robots are designed to do a specific set of operations, such as welding car frames. They are rarely built to resemble humans.
W: Actually, all they need is a kind of brain to give signals, and a mechanism, such as an arm, to carry out instructions, right?
M: Right. Tiny computers become the brain of these robots. The computer sends signals, in the form. of electronic impulses, to move an arm and a claw. The claw is the hand that does particular kinds of work.
W: OK. But we've had machines on assembly lines 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 each 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.
What kind of robots does the man refer to?
A.Agricultural robots.
B.Industrial robots.
C.Computers.
D.Electrical robots.
