Hello! My name is Susan. I have many books, but I don't know what to do with(处置) some old books. Now, in our school library, there is an interesting activity called Bookcrossing (图书漂流). We can take an old book to the library on the first day of each (每个) month. Next, we can look for an old book we like. After we read the book, we need to write (写) our names on it. Then, we must return (归还) it to the library, That's really great. We can read many books and we don't need to pay（付款） for them at all. 

Look! This is a book from the bookcrossing. The name of it is Heidi. It's about a girl and her grandpa. I love the book because I think Heidi is a very good girl. The book is old, and I can see the names of Cathy, Daniel, Sophia and Jenifer on it. There is a card in it, too. It says. "Dear friends! This is a great book. Thanks for reading it!"

The bookcrossing helps me have a good habit of reading. I read one book a month. What about you?
