As society advances and basic needs are most often being met, things that were not considered important in the past have taken priority(优先). In the past, people could easily get a job and progress pretty well, as long as they were hard-working; education was important but not as crucial(关系重大) as it is today.

Nowadays, just as clothes are important to first impressions, degree is important to a person’s first job interview or even a job with a good salary. Although experience is important to survive in any trade or profession, the first thing that companies look for is that piece of paper before looking at one’s experience.

A passport into the world of any profession is what having a degree means today, especially for professions that have need of certification and pay well, such as architects, doctors, lawyers, and teachers.

That piece of paper, the degree, is also a passport to jobs in top or middle management in any company, especially so for multi-national corporations(跨国公司). Having a degree opens up opportunities that one would not have had if one did not have any kind of degree. A degree simply proves that one has gone through the necessary training and understanding of how to carry out a job.

Although there are many that may say having a degree may not necessarily equal to success, it would most definitely help any person achieve success in shorter and easier steps. Success cannot simply be a result of hard work and/or depending on one’s experience or degree alone; it is the art and knowledge of how to work that determines one’s success. Therefore, it should not be for the sake to get a degree, but the quality of the degree and experiences that one can learn from that matter as well.

A.People used to be hard-working

B.How important is the degree?  

C.How can we enter the top management?

A.To prove the importance of the first impression.
