SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文：M: Good morning, Miss White. I'm Bill Green. Yesterday afternoon I called you...
F: Ah, yes, Mr. Green, I remember our appointment. You said you have some trouble in finding a job？
M: Yes. You see, personally I think I have got good qualifications. But out of some reason, I often fail during or after the interview.
F: May I have a look at your resume？
M: Sure.
F: Well, first I must say, your resume has outlined your past very well, but only a statement of past can rarely get you inside a company. I suggest you give employers an example of what you can do for them. You may create a new area in your resume. Call it "value offered". In two sentences, state the value you would bring to that particular employer.
M: Hey, I get that point! For example, I can say things like "I can reduce your operations costs by streamlining our shipping department"
F: Exactly. But be specific and create a separate resume for each company you approach. By the way, do you feel nervous at an interview？
M: Oh, yes. I always think these interviewers want nothing but to humiliate us. So I always feel it's like facing your enemy.
F: Then you should give yourself an attitude adjustment.
