高手帮忙看下我的翻译，送国外的推荐信，不能乱来的
Being a professor in Shanghai Finance and Economics University, I had given six lectures to Hua Sheng as an auditing teacher when she studied accountancy there as her second major, and had been her supervisor when she worked as an intern in my credit rating company. She had listened to me so attentively that many of the cases we studied in class were applied to her work effectively.
I was really impressed by Hua Sheng’s performance during her five-week internship. In order to be more competent in the field of credit rating, she volunteered to assume more tasks, and further offered to work overtime with other regular employees. However hard the tasks were, she always managed to fulfill them with flying colors. Such devotion to her career even as an intern is rarely seen in her peers. As she had done well in her accounting major, with an average score of 85 for the core courses, in addition to her remarkable learning ability, Hua Sheng was capable of doing some of the basic businesses in the company, and thus understanding the know-how of accounting more profoundly. She visited and researched fifteen companies in all, big or small, home or abroad, within the twenty-five weekdays. I could see a clear mind and a strong logic in her participation in writing credit rating reports. She was able to accomplish her own assignments independently while at the same time communicating smoothly/articulately/explicitly and cooperating excellently with all of the five teachers, who had given her some instructions during the internship, further she had raised a few profound questions in the specialty of credit rating. All in all, her work was highly appraised by everyone in the company.

我是财经大学会计学院的博士生导师，盛桦是我校会计专业辅修课学生，我曾担任该学生的审计学老师和实习指导老师。她上课很用心，我讲过的很多案例，在她参与资信评估的实习时，能得到运用。
实习期间，盛桦给我留下了非常好的印象。为了能学习更多的评估专业知识，她主动承担了更多的工作，像正式员工一样主动留下来加班。并且不论工作难度高低，她都能尽心尽力地做好，这样的敬业精神实属难得。她会计基础牢固，核心课程平均成绩85分，加之学习能力较强，因此实习期间她已能较好地掌握评估的一些基本业务，而这又进一步使她对会计有了更深的领悟。25天工作日，她共参与调研了包括上海建桥学院、海航酒店集团等15家公司。在参与撰写评估报告时，她思路清晰、有较强的逻辑性；在独立完成一部分工作的同时，能较好地与老师沟通、合作，并能提一些有深度的问题，得到了大家的一致好评。
参考答案:最好不要冒充别人写推荐信，因为虽然国外一般不会去检查但是就是只怕万一了，而且，推荐信一般还要写明推荐者的头衔和联络方式的。最好还是写成自己推荐自己的personal statement比较好。
