定语从句 This is the book that you are looking for the book.为什么后面要把the book 删掉
This is the book that you are looking for the book.为什么后面要把the book 删掉?This is the book that you are looking for.
那如果我改为：This is that you are looking for the book.这句就成了表语从句了,

解答

因为前面的引导词that就是代替先行词the book 在从句中作for的宾语了,再加上它就重复了,这是定语从句的内容,that属于关系代词,代替前面的先行词在后面的从句中作宾语、主语、表语等
至于你后面的句子也不对,其实最简单的就是This is the book you are looking for(that在从句宾语可以省略）
