W: Good morning, Professor James. I' ve come here to look for a part-time job this term. I wonder whether you have any positions open.

W: American literature.
M: Very good. Have you had any experience in teaching?
W: Yes, I had been a teacher of English for five years before I came here.
M: Perfect. Now can you help me correct the written work of my under-graduates?
W : I' d be happy to try. It would be very challenging, of course.
M: I should think so, but it' s good for you.
W: Yes. Could you give me some idea about the load?
