参考答案：Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice.Students'' opinions differ greatly on this issue.Some hold that priority should be given to start a business of your own, but others take the attitude that finding a job is the best choice influencing their future.
As to myself, I prefer the latter view.An opportunity to start a business exerts a tremendous fascination on a great number of people, with no exception to me.In my view, With the competition in the job market becoming increasingly fierce for college graduates， some ambitious students have tried their hands at launching their own businesses.Over the years，there have been many successful cases of student entrepreneurship and such attempts should be encouraged and promoted by both the universities and the society at large.What’s more ,College students who start businesses are pioneers，among whom will be born China’s future business leaders.Faced with unknown challenges， they are audacious enough to embark on a perilous journey while most of their peers enjoy stable salaries by working as white-collars at high-end office buildings.
All in all, the essential difference between the students who find a job or those students who create their own businesses is that the former are docile followers whereas the latter are aggressive trailblazers.For this reason， business-launching college graduates are more admirable， and thus they command our deep respect.

参考答案：
Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice.Students'' opinions differ greatly on this issue.Some hold that priority should be given to take a job, but others take the attitude that going to a graduate school is the most critical factor influencing their future career choices.
As to myself, I prefer the latter view.A higher educational background exerts a tremendous fascination on a great number of people, with no exception to me.This phenomenon that the graduates have difficulties in finding job after their graduation can easily be found anywhere in our daily life, especially on campus.On the one hand, with the improved high education of Chinese college students which directly brought the result that there are more and more graduates every year.On the contrary, job vacancies don’t increase that fast.More people, less food, which is the exact deion of the hard condition.On the other hand, more and more people go on to pursue their master and doctor degree; more and more Chinese oversea students come back to China to hunt better working chances.It is sure that the competition is more and more fierce.
Therefore, it is high time that we took effective measures to improve our own competitiveness.That is the secret of success in the future employment market after our graduation.
