In current market, almost every enterprise have to face the fierce competetion to stay alive. Excellent service plays an important role in enhancing the company’s competence. There are many problems existing for companies to offer service. For instance, the service quality is poor or provided not in time, all of which cause bad effects on company’s image. Perhaps some companies will prolong their working time to solve such problems. However, I don't assume this solution can really eliminate these existing problems. Because extended time means employees will be forced to sarcrifice their leisure time, which might results in tention and far as I’m concerned, I think it is advisible to improve the quality of service instead of merely increase working time. For most customers, they put great attachment on the quality of service.

Therefore, companies should pay more attention to the improvement of their service.我感觉你的要点太多,所以前两点写在第二段里,后两点写在第三段里,而且举了个海尔的
