I find this book interesting.

Question

能不能改成I find this book is interesting.

Answer 1

两种都可以
原句是interesting 做book 的宾补
I find this book is interesting. 是理解成宾语从句，省略了that

还可以用形式宾语it
i find it interesting to read this book

Answer 2

应该不能
I find this book is interesting我发现这本本书是有趣的
I find this book interesting我发现这本书有趣
觉得I find this book interesting不符合语法
有帮助请釆纳，不懂可追问，谢谢

Answer 3

可以。I find后可接句子。

Answer 4

原文是习惯用法。
