听力原文: Nowadays, there is a growth and apparent success of a specialized service, which offers help to construct resumes and to provide information to job hunters. Of course, this is a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae, with the suggestion that it may now qualify as an art form. in its own right.
There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams", was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.
Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. "Your search is over. I am the person you are looking for", was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.
There is no doubt, however, that it is increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.
