题目内容
听力原文： Those who had seen the film at previous sessions are divided into groups studying the elements of a petroleum-free community: food, water, shelter, health and medicine, and alternate energy sources. The energy group, which includes two solar equipment installers and a re- tired engineer/physicist, will study existing alternative energy sources and determine which are possible here. Also on the list are alternate-fuel transit systems, energy waste and conservation potential, and the offerings of at least two bio-diesel suppliers. The shelter group is considering such alternate building styles and how much of the needed material can be produced locally. Group members want to know how many people will need housing in the future and how to develop new housing without jeopardizing agricultural land. Opportunities for making existing housing more energy efficient and building shared-housing communities are also on the list. The health and medicine group is looking at incorporating alternative heating systems in the incoming hospital, social service networks, local cultivation of medicinal plants, and legal obstacles to alternative medical approaches.
The water group wants to know the amount needed for a family of four and the possibility of salvaging more of the rainy season's abundance.

听力原文：W: Hi, Frank. What are you up to？ Is that really a French grammar book？
M: Well, I'm trying to teach myself some French. When I go to Montreal next semester, I don't want to sound like just another tourist. Most of the people there are bilingual.
W: Leave Boston to go to Montreal？ I didn't know this university had a program in Canada.
M: It doesn't. I'm planning to take a short leave of absence from school, so I can go there on my own.
W: What's the reason for this sudden interest in Canada？ M: Well, actually I've been thinking about going for some time now. I know someone there who's been wanting me to visit.
W: A relative？
M: An old friend of my uncle's runs a chemical engineering department there. So, I'm hoping he can help me enroll in some interesting courses.
W: If you want those credits transferred back here later on, you'd better arrange for it before you leave. Don't forget what happened to Susan after she came back from Rome.
M: Yeah, but her situation was different. I already have all the credits I need to graduate.
W: So you'll be taking courses just for the sake of learning.
M: That will be a nice change of pace, won't it？
