听力原文： Man: My secretary tells me that you'd like to know something about mechanical engineering. What I can do is give you some idea of the variety of specialties within the field.
Woman: I'd appreciate that very much.
Man: One of the oldest mechanical engineering areas is machine design. First, we need to know the purpose, of a particular machine, whether it's a crane or a tool or a steam engine. Then, if we know the loads that this machine will carry, we can make the most efficient use of the materials we have.
Woman: I see. Is heating included in this field？
Man: Oh, yes. Heating, refrigeration, and air conditioning rely quite a lot on thermodynamics and theories of heat transfer. The goal is to make the most efficient use of power. This area can be quite involved with mathematics.
Woman: I've heard of the Carnot cycle. Does this concern the mechanical engineer？
Man: Very much so. The whole field of internal combustion engines is based on the principles set out by Carnot. The mechanical engineer deals with two and four-cycle engines, gasoline and diesel engines, gas turbines, and the like.
Woman: Isn't that part of automotive engineering？
Man: Yes. This is one of our largest industries.
Woman: What about the aircraft industry？
Man: Of course. Aeronautical engineering became a very large field with the widespread use of airplanes. Now, with space travel, it promises to grow even larger.

听力原文：W: Mr. Atkins, Would you please tell the court what you were doing when the accident happened and what you saw？
M: Yes, I was driving home from work. It was about 5:15, and there was a blue car in front of me. We were both driving along Harbor Road when a small white Ford suddenly shot out of a side road. It shot right in front of the blue car. The driver tried to stop, but it was impossible. He ran into the white Ford.
W: I see. Now, how fast was the car in front of you going when the accident happened？
M: The blue car？ 30 miles an hour. Certainly no more than that.
W: And the white Ford shot out without any warning？
M: Yes, that's right.
W: Then, how can you be sure the blue car was only doing 30？
M: Because I was only doing 30, and the blue car wasn't going any faster than I was.
W: Are you sure of that？
M: Yes, I am. I'm positive.
W: How can you be so positive, Mr. Atkins？ Were you looking at your speedometer when the accident happened？
M: Of course not. I was looking at the road ahead. That's how I managed to see the accident!
W: Well, if you weren't looking at your speedometer, how can you possibly be sure how fast you were going？
M: Because I never go faster than 30 on that road.
