It is Sunday today but my three good friends are not at home. Tina is at the mall. Is she shopping? No, she isn't. She is eating lunch with one of her friends. Mike is still at school. Is he doing his homework? No, he isn't. He's playing basketball with other boys. What about Lisa? Where is she? She is at the library. She is reading a book. Is it an interesting book? Yes, it is. Lisa likes this book very much.
