[听力原文] I just wrote the speech for the election. You know, I’m running for a class president. I was wandering if you would mind looking it over. Hey, what a friend’s for -Excuse me, I’ve been using this old book for a research project and I noticed that a lot of pages are turning brown and becoming brittle. -Yes, unfortunately, that’s a common problem with books made from wood pulp. -I suppose to make paper from wood that you have to add a lot of chemicals and acids to make it turn white. -Exactly and it’s the acid that eventually eats away the paper. -Oh, that actually make sense, but this book’s not even 75 years old and I’ve seen books in museum that are hundreds of years old and they’re in fine condition. -Well, you see, books have been made from wood pulp only since 1850’s, before that they were made from materials mostly animals’ skins or C, no chemicals were added. -It’s a shame those older wood pulp books are going to fall apart some day. Is there anything that can be done to preserve them. -En, currently the only way to stop the books from decaying is to remove the binding and treat each page individually to remove the acid. -That doesn’t sound very economical. -No, it isn’t. It’s not practical to treat a large number of books with this process, so we only try to rescue the most valuable 1st edition books in our collection. -Well, thanks for the explanation. I’d better get back to my project. -Good luck, and I hope the old book hold long enough for you to finish it. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
