Dear Mr. Li,

I’m Wangtao. I’m written to tell you my opinion about employing a foreign language teacher.

They are two factors to take into consider. For a thing, the sense of humor is necessary for a teacher, who makes his class interesting and lively. For another, ensure efficiency in teaching and learning, the foreigner’s ability to speak Chinese matters much, so only with the help of Chinese can they communicate with each other smoothly.

Various of activities out of class, such as English Evening and English Corner, should be organized by the foreign language teacher, which brings the students more chances to communicate with the teacher and improve his oral English.
