听力原文： In 1871 the first passenger elevators were used in office buildings and allowed architects to build higher than people could comfortably walk. Another improvement was in building technique. In 1885 the steel skeleton was introduced and allowed for the construction of tall buildings that could withstand high winds. We take for granted some of the other inventions that enabled people to live and work in skyscrapers. For example, few people realized that the telephone was necessary for vertical communication and that flush toilet and vacuum incinerator(a machine designed to burn things in order to destroy them) made waste 'disposal possible. Now as we entered the age of super skyscraper, some with more than 200 floors, we see the need for even more technological improvements. In the area of heating and cooling systems for example. For all their benefits, these super tall buildings do cause problems though. For one thing they place enormous strain on parking and traffic row in urban areas. But let's leave behind these technical concerns and move on to consider some of the design elements that have come to characterize the age of the skyscraper.

听力原文：W: Sir, you've been using the online catalogue for quite a while. Is there anything I can do to help you？
M: Well, I've got to write a paper about Hollywood in the 30s and 40s, and I'm really struggling. There are hundreds of books, and I just don't know where to be gin.
W: Your topic sounds pretty big. Why don't you narrow it down to something like..., uh...the history of the studios during that time？
M: You know, I was thinking about doing that, but more than 30 books came up when I typed in "movie studi os."
W: You could cut that down even further by listing the specific years you want. Try adding "1930s" or "1940s" or maybe "Golden Age",
M: "Golden Age" is a good idea. Let me type that in...Hey, look, just 6 books this time. That's a lot better.
W: Oh...another thing you might consider..., have you tried looking for any magazine or newspaper articles？
M: No, I've only been searching for books.
W: Well, you can look up magazine articles in the Reader's Guide to Periodical Literature. And we do have the Los Angeles Times available over there, you might go through their indexes to see if there's any thing you want.
M: Okay. I think I'll get started with these books and then I'll go over the magazines.
W: If you need any help, I'll be over at the Reference Desk.
M: Great, thanks a lot.
