你好,作为翻译而言,本身需要尊重原文,但是我个人觉得原文开头过于重复累赘,所以有所选择的省略.比如“时间转瞬即逝”（感觉）和“觉得时间过得真快”,这个没有必要重复描述.
还有“我相信”改为“我承诺,我保证”之类的,更见诚意吧,不是吗?
前面几位译者,就算用翻译器,也总该检查一下吧,那么多语法错误……
How time flies! It will be the end of my college English course. We are going to take the last lesson today. In the past two years, our teacher not only taught us college English, but also enlightened us about the truth and the experience of life. With our teacher’s instruction, my English proficiency has been so greatly improved that I even passed CET4. I should owe it to our teacher!
I promise that I will never give up English learning. I will keep in mind what the teacher have taught me and try to make full use of English in the future of my life. I will do my best to improve my English and strive to reach the level of our teacher.
