听力原文：W: Well George, you can approach my desk now. (19) I have done an appraisal of your application to be my apprentice, and I have a few questions for you. (20) (21) You don't seem to have any apparent experience in working with large aquatic appliances. You do know that the aquariums I clean and make are not for goldfish or restaurant shelves, right? M: What else can be put in them? W: They put sharks, whales, and seals in them. Well, I applaud your effort and appreciate your coming across town for this interview, (20) but you don't have the experience or aptitude that is usually required for this type of apprenticeship. M: I am very appreciative of your assessment of my qualifications, Madam. But I'd like to appeal, to you to give me a chance. (19) I know I know nothing about aquariums. I come from the desert and that's why I came to California to work with water. (19) And I know you will approve of determination. I have that and hope you could give me a try. W: Okay George, (22) I'll take a risk and give it a try. But you are up for three-month probation. We' 11 take a look at how you're doing in these three months and make the final decision. M: Thank you, Madam! You won't be disappointed! (23)
