【答案解析】[听力原文]
   Nicole: Mark, I am truly impressed with how successful the Earth Day Groceries Project has been. How did this all come about?
   Mark: I got an Internet account in 1993 from NASA that was very exciting and got on some educational discussion lists. I tried this project at my schools: borrowing grocery bags from the local supermarket with the agreement that the kids would decorate them and bring them back, and the store would distribute them to customers on Earth Day, April 22. It would be an environmental education project where the students were actually empowered as teachers to educate their community on the importance of Earth Day and of protecting their environment and so on. And they did that through the artwork that they put on each grocery bag. It was a huge hit. I involved most of the school the next year. And after that, I wanted to share it even more. The Internet was just starting with discussion lists for educators, and so I sent this invitation out to Ednet and Kidsphere in 1994. I received responses from 43 schools, mostly in the U.S. and Canada. There were about 15,000 bags decorated just through this one little announcement! I was just blown away. The power of this medium is something! That summer I began building our school website. And for the first 4 years of this project, the Earth Day Groceries Project was part of that site. It continued to grow. I established it with its own domain name several years ago, and 2 years ago, I set it up as a nonprofit organization. I still run it myself, but we do have a board. The reason for doing that is that it become a very big project in terms of the amount of time required.
   Nicole: Looking at the website, it's clear that a lot of time and effort went into the project. How did you develop the skills you needed to construct the site?
   Mark: There were no books on HTML (hypertext mark-up language, the tagging system used to create most WebPages) published when I started working on the school website. Basically, I went to a few websites, and I looked at the source of the WebPages. I learned how to copy and paste, put my own information in, and look at the page locally. That's how I learned how HTML worked. Then I found a very simple HTML editor and learned a little bit more. So, I was self-taught, and trial and error was one of the first ways that I got started.
   Nicole: How have things changed since then?
   Mark: Now there are a lot books, and terrific online resources and courses. The opportunities to learn are all over the place. The biggest challenge for teachers is finding the time to do it. that's the biggest challenge for me—just finding the time to keep my skills.
   Nicole: Jean, introducing computers into the classroom seems like a somewhat unlikely thing for an art teacher to do. What prompted you to do it?
   Jean: I started constructing webpages a couple of years ago, and just continued to develop with it. being an art teacher, I like doing anything visual, and doing webpages became a way for me to become visually and "artically" challenged.
   Which of the following statements is TRUE about the Earth Day Groceries Project?
主旨题。Mark在访谈开始介绍活动的时候就明确指出The Earth Day Groceries Project是一项环境教育活动(It would be an environmental education project...),因此本题正确答案为D。
