     Each new school year brings fresh reminders of what educators call the summer learning gap. Some

call it the summer learning setback. Put simply, it means the longer kids are out of school, the more they

forget. The only thing they might gain is weight. Recent studies show that children gain weight more

quickly in the summer vacation than when they are in school.

     Most American schools follow a traditional nine-month calendar. Students get winter and spring

breaks and about ten weeks of summer vacation. Some schools follow a year?round calendar. They

hold classes for about eight weeks at a time, with a few weeks off in between. But many experts point

out that the number of class days in a year-round school is generally the same as in a traditional school.

     Last year, a study at Ohio State University reported that year-round students did not learn any more

than other students. Lead researcher Paul von Hippel said "year-round schools don't really solve the

problem of the summer learning setback. They simply spread it out across the year".

     Across the country, research shows that students from poor families fall farther behind over the

summer vacation than other students. Experts say this can be prevented. They note that many schools

and local governments offer the programs that can help.

     But calling them "summer schools" could be a problem. The director of the summer learning center

at Johns Hopkins, Ron Fairchild, recently wrote about this issue on his blog.

     He said that in American culture, the idea of summer vacation is connected to the beliefs about

freedom and the joys of childhood. He said research with groups of different parents in Chicago and

Baltimore found that almost all strongly disliked the term summer school. They said it created an image

of children being forced to do work they missed during the school year.

     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. much competition has to be faced

B. many employees have no working experience

C. the young people only care about how much they can earn

3. In the writer's opinion, which of the following statements is most important?

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.

D. Your job must not ruin your talents.
