who said or wrote and to whom?这句话怎么理解?后面的to whom

英语翻译who said or wrote this ,这一句我知道是什么意思,但我知道and to whom?的意思和 Whom who whom to be neither 这句话为什么用who 不用whom啊 .who does this book belong to? Success belongs to who never give up.这句话对吗?who是不是应该改为whom. I am the person.I wrote to you.用who或whom连接句子 to whom 和 for whom 的区别 who to ask还是whom to ask 定语从句的使用就是who,whom,to whom的用法! This book belongs to whom/who? He is the man whom I invited to the party.这句话中可不可以省略whom 英语语法 to whom 的用法 怎么理解：Tell me whom you love,and I will tell who you are.
