暑假作业快乐假期新疆青少年出版社系列答案

In his eyes, books and summertime just don't go together. He thought he had read a lot during the school year. And he had never set foot inside a public library. Today he'd just drop the books off in the outside return box, but it was locked. He had to go inside to return them.

David walked inside the building a few minutes before closing time. He put the books into the return box. After a quick drink of water and a short stop in the toilet, he'd be on his way to meet Jim. He walked out of the toilet. The library lights were turned off. He was locked—in a library!

David tried to use the telephone, but he couldn't find one. As the sun began to set, he searched for a light and found a little one on a desk. He used a pencil to write a note on a big piece of paper. It read, “I'm locked inside. Please call for help.” He put it on the front door. Surely, someone passing by would see it. He then turned his attention to the library itself.

He was surprised to discover that this place was not so bad. Rows and rows of books! When he saw a book about Michael Jordan on the desk, he picked it up. He opened the book and began to read. He felt that being locked in the library didn't seem to be such a terrible thing.
