1、holding a book（holding 现在分词作后置定语,修饰男孩的状态）
2、The name of school
3、There is/are/... no 或 There isn't any 例子：There is no book on the desk.或There isn't any book on the desk.
4、Is/are... there ...? 例子：Are there any books on the desk?
对于第3、4点的补充：
is there any?表达是不可数名词的单数时使用.is there a?表达的是可数名词的单数.are there any?表达是可数名词复数时的用法.
希望对你的学习有帮助!
