A．They are newer than the formations in most caves.B．They were formed by sulfuric acid
W: Hi, Bill. So wonderful! I can't wait to hear about it!
M: Recently, I visited the La Chagire Cave in New Mexico, my dream has always been to discover a new passage way. I had a chance there, because La Chagire is so large that discoveries are frequently made there.
W: Was it newly discovered？
M: The cave was not even discovered until 1986.
However, people in that area had figured that there must be a cave nearby, because of the strong wind that blew from behind the huge rock that covered the entrance. Enormous amount of air enter and exit the cave in order to maintain balance of the pressure with the inside air.
W: You must have had to fight heavy wind when you were in the cave.
M: Exactly, I had to fight 45 mile per hour winds. After all that effort, I had to be extremely careful maintaining my energy level. People who are tired tend to be careless, and may be more concerned about getting out of the cave than taking care of it.
W: Anything interesting or thrilling in the cave？
M: There are formations in La Chagire that look like ocean waves, Christmas trees and other stuff no one has ever seen before.
W: Caves are normally created by carbonic acid, right？
M: But this cave sculpted out by very powerful sulfuric acid that swells up from below.

听力原文： A man once said how useless it was to put advertisements in the newspapers. "Last week," he said, "My umbrella was stolen from a London church. As it was a present, I spent twice its worth in advertising, but didn't get it back."
"How did you write your advertisement？" asked a businessman.
The man took out of his pocket a slip cut from a newspaper. The other man took it and read, "Lost from the City Church last Sunday evening, a black silk umbrella. The gentleman who finds it will receive ten shillings on leaving it at No. 10 Broad Street."
"Now," said the man, "I often advertise, and find that it is always useful. But the way in which an advertisement is expressed is of great importance."
The businessman then took a slip of paper and wrote: "If the man who was seen to take an umbrella from the City Church last Sunday evening does not wish to get into trouble, he will return the umbrella to No. 10 Broad Street. He is already known."
This appeared in the newspaper, and on the following morning, the man was astonished when he opened the door. In the door way lay at least twelve umbrellas of all size and colors that had been thrown in, and his own was among the number. Many of them had notes tied to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter.

听力原文：M: Excuse me, Prof. Thomson. I know your office hours are tomorrow, but I was wondering if you have a few minutes free now to discuss something.
W: Sure, John. What do you want to talk about？
M: Well, I have some quick problems about how to write the research project that I do this semester about Climate Changes.
W: Oh, yes. You were looking for changes in climate in the G city area, right？ How far have you been gotten？
M: I've gotten my data, so I'm starting to summarize it now, preparing graph and stuff. But I'm just...I'm looking at it and I'm afraid that is not enough, but I'm not sure what else to put into the report.
W: I hear the same thing from every student. You know, you have to remember now that you are the expert on what you have done. So think about what you need to include if you're going to explain your research project to someone with general or casual knowledge about the subject like your parents. That's usually my rule. Would my parents understand this？
M: Uhh, I get it. I was wondering if I should also include the notes from the research journals you suggest.
W: Yes, definitely. Be sure you include good reference section where all your published and unpublished data came from.
M: Yes. I have data more than just in the G city area, so I also include regional data in the report. With everything else, it should be a pretty good indication of climate of this part of the state.
W: Sounds good. I'll be happy to look over a draft before you hand the final copy if you wish.
M: Great. I plan to get you the draft of the paper by next Friday, Thanks very much. See you.
W: OK.
