听力原文： The great advance in rocket theory 40 years ago showed that liquid-fuel rockets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large solid-fuel rockets with solid fuels about as powerful as liquid fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better". The question is meaningless; one might as well as ask whether a gasoline or a diesel engine is "better". It all depends on the purpose. A liquid-fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The burning of the rocket engine can be stopped completely; it can be reignited when desired. A solid-fuel rocket, on the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid-fuel rocket has to be fueled first and can not be held in readiness for very long after it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid-fuel rocket can be kept ready for a long time, most military missiles employ solid fuels, but manned space flight needs the fine adjustments that can only be provided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fuel rocket is, by comparison, cheap.

听力原文：M: Excuse me, are you waiting to buy concert tickets？
W: Yes, I am. So are all these people in front of me.
M: Have you been here long？
W: About 45 minutes. I've moved forward a total about 3 feet in that time.
M: You're kidding!
W: Not at all. There was a couple up ahead of me who got so disgusted they finally gave up and left. They said they'd been waiting for more than an hour.
M: Does anyone know what's causing the delay？
W: If so, no one's letting us know. It could be that there aren't enough people selling tickets this afternoon. Or maybe their computer's down. I'm sure the concert hasn't been canceled.
M: I just hope they don't run out of tickets before I get up there.
W: That really would be annoying, wouldn't it？
M: I guess I should have come before lunch. Or has it been like this all day？
W: Apparently it has. In fact, before I came, I tried calling to charge my tickets over the phone, just to avoid this long wait, but they're not taking phone orders, or checks, or credit cards. It's cash or nothing. And you have to come in person.
M: Well, there're two more hours before the ticket office closes. Tickets to a good concert are worth waiting for. So I think I'll just make myself comfortable.
