Dear Manager,
My name is Ming Li, a high school student. I am looking for a summer job and I believe my skills and background are perfect to fit the position you are hiring.
I have very good English language skills and have no problems communicating with English speakers. Besides, I love invention which is part of my life. I have achieved two patents on my inventions, and I am still working on some other small invention projects. Hope I can be a great well-known inventor, like Einstein. I am easy going, active and passionate with new things.
I am looking forward to your reply and an interview will be very much appreciated.
Sincerely,
Ming Li
没数字数,希望符合你的要求.不过如果你是高中学生的作文,我觉得我这篇求职信可能已经超出了你老师的水平.建议修改后再用,以免有不必要的麻烦,呵呵.
