【正确答案】 D

【答案解析】[听力原文]
   M: Hey, any idea of what to do this summer vacation? There doesn't seem to be any jobs available.
   W: Why don't you try house-sitting? Last summer my friend Marsha house-sat for the Howards when they went away on vacation. Mr. Howard hired Marsha to stay in their house because he didn't want to leave it empty.
   M: You mean the Howards paid Marsha just to live in their house?
   W: It wasn't that easy. She had to mow the lawn and water the house plants. And when Eric house-sat for Dr. Cohen, he had to take care of her pets.
   M: House-sitting sounds like a good job. I guess it is a little like baby-sitting—except you take care of a house instead of children.
   W: The student employment office still has a few jobs posted.
   M: Do I just have to fill out an application?
   W: Margaret and Eric had the interview with the homeowners and provided three references each.
   M: That seems like a lot of trouble for a summer job.
   W: Well, the homeowners want some guarantee that they can trust the house-sitter. You know they want to make sure you're not the type who'll throw wild parties in their house, or move a group of friends in with you.
   M: House-sitters who do that sort of thing probably aren't paid then.
   W: Usually they're paid anyway just because the homeowners don't want to make a fuss. But if the homeowner reported it, then the house-sitter wouldn't be able to get another job. So why don't you apply?
   M: Yeah, I think I will.
   What does the man plan to do this summer?
