我下了老托的听力段子，听完以后发现所提供的原文有一些有好多错误的地方，下面是我结合原文的基础上听出来的一篇，自己觉得还是比较正确的。希望不是水贴，能给大家一点帮助。

La Chagire cave

alatino Linotype"; mso-bidi-font-size: 10.5pt; mso-bidi-font-family: Kartika;">Hello Everybody. I’m here today because I’ve visited caves all over North America. Since you’re going to study cave formations, Dr. Bow asked me to come and share some of my experiences with you. In addition to describing some technical aspects about caves, I want to convey the sense of adventure that caves share. Recently I’ve visited the La Chagire Cave in New Mexico. My dream has always been to discover a new passage way. alatino Linotype"; mso-bidi-font-size: 10.5pt; mso-bidi-font-family: Kartika;">I had a chance here because the La Chargire is so large that the discoveries are frequently made there. The cave itself was not even discovered until 1996.

Enormous amounts of air enter and exit the caves in order to maintain a balance of pressure with the outside atmosphere. When I climbed into the caves, I had to fight 45 mile an hour wind. After all that effort I had to be extra careful about maintaining my energy level. People who are tired tend to get careless and may be more concerned about getting out of the caves than taking care of it. There’re formations in La Chargie that look like ocean weaves, Christmas trees and other stuff no one has ever seen before. Caves are usually created by carbonic acid that trickle down from above. But this cave was sculpted out by very powerful sulfuric acid that rose up from below.

再来一篇，也是地质篇里面的

alatino Linotype"; mso-bidi-font-size: 10.5pt; mso-bidi-font-family: Kartika;">We only have a few minutes left so I’d like to go over a couple of points before we move on. Remember that although there are both horizontal and vertical movements of air, the term wind is applied only to horizontal movements, and that more air is involved in those horizontal movements than in vertical movements. And what causes these horizontal movements? Ultimately it is solar radiation because the unequal heating of the earth and the atmosphere produces horizontal differences in air pressure. These differences set winds in motion. Essentially winds are nature’s way of balancing out the uneven distribution of air pressure over the earth. Secondly, let me repeat my answer to the question we had before about wind direction. Many people get confused by what they hear in weather forecasts. We talk about wind direction in terms of where the wind’s coming from not where it’s blowing to. There is good reason for this. To weather forecasters the origin of the wind is more important than its destination. The wind’s origin helps them predict the weather. Logically in the northern hemisphere, a north wind tends to bring colder weather and the south wind warmer weather. I haven’t forgotten the vertical movements of the air but we don’t have time today to talk about it in depth. In our next class then, I will begin by discussing about updraft and downdraft and how they affect the weather. I suspect most of you can guess which of the two brings warm weather and which brings cold.
