from cover to cover from end to end 都是从头到尾的意思 有什么区别啊```再给举几个例子吧！！！

from cover to cover 是指书的封面从前到后.例如:

He read the book from cover to cover.
他从头至尾读了这本书。

You are not required to read it from cover to cover.
并不要求你从头读到尾。

from end to end 是从这一端到另一端, 从头到尾地.例如:

He travelled France from end to end.
他从法国的这一头儿开始旅行一直到达了法国的那一头儿。

也可以包含from cover to cover 的意思,如:I have read your book from end to end.
你的大作我已从头到尾读过了。
