听力原文： To be successful in an interview, you should demonstrate certain personal and professional qualities. You need to create a good image in a limited time available, usually from 30 to 45 minutes. You must give a positive impression which the interviewer will remember while he interviews other candidates.

You should especially pay attention to some qualities during the interview. First of all, you should take care to appear properly dressed. The fight clothes worn at the fight time can win the respect of the interviewer and his confidence in your judgment. It may not be true that clothes make the man, but the first and lasting impression of you is determined by the clothes you wear. Secondly, you should pay close attention to your manner of speaking. Since speech is a reflection of personality, you should reflect confidence by speaking in a clear voice, loud enough to be heard without being aggressive or overpowering. You should be prepared to talk knowledgeably about the position you're applying for. Finally, to be really impressive, you must convey a sense of self- confidence and an enthusiasm for the work. If you display these characteristics with just a little luck, you'll certainly succeed in a typical personnel interview.
