Dear Mike,

    How are you doing these days?

    Aimed at providing a platform there students can have a chance to exchange and make use of their books, the annual campus books fair will soon held in our school. The fair will attract a huge crowd from the entirely school, who are to sell, purchase but exchange their second-hand books with their peers.

    As a regular visitor, I've found myself increasingly drawing by the fair. For one thing, the fair exhibits books of hundreds of type on diverse topics, motivating us to further develop their reading habits and help to broaden our horizons. For other, most books are sold at a low price than what the bookstores offer.

    Please let me to know if you have any suggestions on how to host such a book fair better.

As the old man looked over the things in the yard that was to be sold, he stopped at a box of golden ball for Christmas trees. On the box was a card say, “25 cents each.” “You will never sell these for that much.” he told Nick. Convincing, Nick has brought the price up to 10 cents a piece.

    Last weekend, our class went hiking. Early in the morning, we gathered at People's Square in the city center and then head for the South Mountain, which was 8 kilometers away. Our goal was to climbing to the top, from which we could enjoy a good view.

    It was an exhausted hike and the heats consumed all our energy. Therefore, when we finally reached to our destination, the view took our breath away. It was well worth walking such long distance. Because I not only got relaxed by enjoying the beauty of nature but also learned the truth which our efforts will always pay off in the end.

    My hobby is rock climbing. I've been doing them for two years. In the beginning, I wasn't very good, so I've gotten much better. I started rock climbing in junior high school. On first day, I felt high nervous, so I only climbed low rocks. It was hard, but very interested. So I kept on work, and now I could climb very fast. I like rock climbing because of it helps me stay in shape. It's also a good way to make friend. I've met a lot of people. We climb, but we also hang out and spend time doing another things now.
