Directions: In almost every vocation, college students are supposed to undertake such activities as offering their knowledge to those who need most, performing some social investigations, taking part time jobs, or volunteering to do whatever that the society needs. Write something you did that was worth mentioning in previous summer vocation as a letter to one of the editors of a newspaper. You should write about 100 words on ANSWER SHEET 2. Do not sign your own name at the end of the letter. Use "Li Ming" instead. You do not need to write the address.
