Directions: As part of a student social survey project, you are leading a group to visit an exhibition in a small town. Write a letter:

　　Dear Sir or Madam,

　　I am organizing a group of students to pay a visit to the historical exhibition in your town. Therefore, I would be grateful if you could supply me with the following information.

　　First of all, I want to know what is the size of the exhibition, what is its theme and what objects are on display. Secondly, what are the dates between which the exhibition will be held, and what are the daily opening hours? Thirdly, are there any other activities being held in connection with the exhibition?

　　I must point out that I hope to bring over students to the exhibition. So I would like to inquire if there is any discount available on entrance tickets for students. I look forward to your reply.

　　Yours sincerely,

　　Li Ming
