     Too often young people get themselves employed quite by accident, not knowing what lies in the

way of opportunity for promotion, happiness and security. As a result, they are employed in doing

jobs that afford them little or no satisfaction.

     Our school leavers face so much competition that they seldom care what they do as long as they

can earn a living. Some stay long at a job and learn to like it; others leave one for another looking for

something to suit them. The young graduates who leave the university look for jobs that offer a salary

up to their expectation.

     Very few go out into the world knowing exactly what they want and realizing their own abilities.

The reason behind all this confusion is that there never has been a proper vocational (职业的)

guidance in our educational institution. Nearly allfeel their way in the dark. Their chief concern when

they lookfor a job is to ask what salary is like. They never bother tothink whether they are suited for

the job or, even more important, whether the job suits them. Having a job is more thanmerely providing

yourself and your dependants (受赡养者)with daily bread and some money for leisure and

entertainment.It sets a pattern of life and, in many ways, determines social status in life, selection of

friends, leisure and interest.

     In choosing a profession you should first consider the type of work which will suit your interest.

Nothing is more sad than taking on a job in which you have no interest, for it will not only ruin your

talents but also discourage your desire to succeed in life.

A. they are lowly paid

A. much competition has to be faced

A. Your job must suit your interest.

B. Your job must set a pattern of life.

C. Your job must offer you a high salary.
