Dear Sir,

I am writing to introduce myself, with the hope of getting the job you advertised in Daily news.

When I was a child, I was fond of English and always got good grades. In 1995, after six years of hard work in Beijing No. 4 Middle School, I entered People’s University. I studied English there for four years.

Luckily, I got my first job when I graduated. I taught English in Beijing No. 4 Middle School from 1999 to 2002. Then I got the chance to receive further education in University of Hawaii in the US. That was a precious experience of my life. I learnt a lot during those two years, especially the differences between eastern and western cultures.

I came back to People’s University in 2004. I worked as an assistant(助手) for two years and then as a professor. So far I have got 9 years of working experience.

I won lots of awards. I was an“Excellent Student”of People’s University in 1998, and an“Outstanding Teacher”of Beijing No. 4 middle school in 2001.

Thank you for reading my letter, and I will appreciate it very much if you can reply soon.

Yours sincerely,

Li Goulong
