A: W: We are going to change our meeting from Monday to Tuesday.
Problem: Given the question: W: Certainly not. I'm a machine operator working in the assembly workshop. M: Oh, are you? Then you have a six-day week, don't you? W: Yes. And we work eight hours a day, but this includes a one -hour break. M: What about the huge machines used in your factory? I know you make heavy machines yourselves. But I wonder if you also use machines imported from abroad. W: Most of them are made in China, some even by our factory. Only a few were bought from other countries. M: But I see the machines turned out here are quite modem and efficient. W: Following the national policy of self - reliance and hard - working struggle, we've tried our best in the past few years to improve our equipment. However, there is still a lot more to do. M: Now the question about yourself. I hope you don't mind it. How much do you earn each month? W: My monthly wage is 3,500 RMB, not including the extra pay of about 500 for extra work I put in. M: That sounds reasonable indeed. I'm very interested in worker's welfare here. What other benefits do you workers get, I wonder? W: Like other factories in China, our factory offers free medical service for workers. What was said before this conversation?
