M: Hi! Susan!
W: Hi! Mike! What’s going on? You look rather worried.
M: (12) My parents just called me and said they couldn’t afford my tuition next semester. I have to earn that by myself! but I’m not sure if I can find work this summer vacation. There aren’t many jobs for inexperienced workers like me.
W: I’m sorry to hear that. After all it’s a big sum of money for a sophomore. Have you been to the Students’ Union? I hear they are collecting employment information for job hunters.
M: Actually I have! but there’s no job offer at the moment. They say they will inform me as soon as they get vacancies. W: Well! have you heard about house-sitting? My friends have tried that. (13) That is! a house owner will travel for his holiday! and doesn’t want to leave his house empty. He may get a reliable person to live in and take care of the house.
M: It sounds great. Is it a paid job?
W: Yes! you will be well-paid! I think.
M: OK! I’ll take any job that pays. How can I get this job?
W: (14) There are a few notices posted in the student dorms.
M: So I just call and tell them I want the job?
W: Not exactly. (15) First will be interviewed by the house others. If they think you are the right person! you can get the job.　　
M: Well! I’d like to try. I think I can do this kind of job well.
W: Good luck.
