该怎样对小学生讲 whose is this book?这句知识点,我觉得不用讲定语从句什么的?

whose在定语从句中的用法,麻烦讲详细点, 同义句转换:whose book is this? whose book is this 的同意句 This is the book+that定语从句 whose is this book? Whose book is this? 谁能帮我讲一下定语从句 Whose book is this和Whose is this book是同义句吗? Whose is this book?这句话对吗? 有关定语从句的两题 我们英语老师讲的（我也觉得对） 就是答案不一样 1.she will never forget he Whose is this book ?对吗? whose french book is this?
