Dear Mike，
How are you doing these days？
Aimed at providing a platform where students can have a chance to exchange and make use of their books，the annual campus book fair will soon be held in our school．（高分句型一）The fair will attract a huge crowd from the entire school，who are to sell，purchase and exchange their second-hand books with their peers．（高分句型二）As a regular visitor，I've found myself increasingly attractedby the fair．For one thing，the fair exhibits books of hundreds of types ondiverse topics，motivating us to further develop our reading habits and help to broaden our horizons．For another，most books are sold at a lower price than what the bookstores offer．（高分句型三）
Please let me know if you have any suggestions on how to host such a book fair better．
Yours，
LiHua．
