听力原文：M: Hi, Sally. W: Hello, Tom. How are you? M: I'm fine. Where are you going? W: Oh, I'm on my way home from work. M: I didn't know you had a job. W: Yeh, I work part-time at a supermarket. M: What do you do there? W: I work in the produce section. Trimming and wrapping fresh fruit and vegetables. I also stock shelves. Sometimes when it really gets busy, I work at the check-out counter. Have you got a job, Tom? M: Yeh, I do yard work for people. You know, cutting grass, raking leaves, pulling weeds, things like that. W: I'd like doing that. It must be nice to work outdoors. M: Sometimes it is. Except when it rains or snows or gets too hot or too cold or... W: Ha-ha, I think every job has its shortcomings. There are times when I get pretty tired of carrying things around at my job. But a job's a job. Gotta earn money for school. M: Me, too. Tuition is very high, isn't it? Well, I must go now. I have to plant some trees for my neighbors this afternoon. W: Well, don't work too hard. Holding down a job, going to class, studying. Sometimes it can become too much for one person. Take it easy. M: You, too. It was great seeing you. Sally! What does Sally do in the supermarket?
