A、He was tired of the boring work. B、He was not satisfied with the salary. C、He found no chance of promotion. D、He found no way

W: Hi Peter! How are you doing these days?
M: Oh, I am trying to shift to another work．(19)And you know it seems very hard to find a job these days because it is a dead season for the employment．
W: That’s too bad. Why did you leave your last job?
M: Well, (20)my boss is very critical, and the worst thing is that I can not see any chance of promotion in the company.
W: That makes sense. A job without opportunities and a critical boss isn’t very attractive.
M: Exactly! So, anyway. I decided to quit and find a new job. (21)I sent out my resume to more than twenty companies. Unfortunately, I’ve only had two interviews so far.
W: Have you tried looking for a job online?
M: Yes, but so many of the jobs require moving to another city. I don’t want to do that.
W: I can understand that. How about going to some of those networking groups?
M: I haven’t tried those. What are they?
W: (22)They’re groups of people who are also looking for work. They help each other discover new opportunities
M: That sounds great! I’ll definitely try some of those.
W: I’m glad to hear that. So, what are you doing here?
M: Oh, I’m shopping for a new suit. I want to make the best impression possible at my job interviews!
W: There you go. That’s the spirit. I’m sure things will look up for you soon.
