go back， come back ，get back 有区别么？

go back 回去
如go back to school...比如You have to go back to school when this summer vacation is over.
所以go back和come back的区别，就是go back是回去
come back是回来

get back的意思蛮多的，不一定是回去到某个地方，还可以使回去/返回到某种状态
比如
I have to get back to work immediately because I haven't finished the proposal yet.
我必须马上回到工作状态，因为我还没有写完我的提案。
get back如果中间加个东西意思就变成把。。。取回
Can I get my book back?
我能把我的书要回来么？
He got his former job back.
他重获旧职。

所以总的来说，关于get back你记住它有三个基本意思就可以了
1. 回到某个地方
2. 返回到某种状态
3. 拿回，取回

go back 一般强调“ 去”的意思，就是从这个地方去（返回）某个地方 例：go back to your home
come back 一般强调 “来”的意思，就是从某个地方来这个地方 例：come back here
get back 一般强调借给某人的东西拿（取）回来的意思 例：get my pen back

　　go back,是回去的意思， Go back to your seat. 回座
　　come back 是回来的意思，My husband will come back in two weeks. 两周后我老公就回来。
　　get back 是回来；恢复；取回；重新上台的意思，It's about eight children who are never going to get back their lives back 大约有8个孩子将永远无法回到原来的生活。
