英语翻译你有听他说什么时候回来吗?翻译成为：“Didyou hear him say at which time he’s come back?”

不通顺！


do you hear when he will come back from him

Did you hear that he say when will he come back?

望采纳~O(∩_∩)O~~

Did you hear him say at what time he is comming back ?
or
Did you hear him say what time he is back ?

是正确的，可以的

好像是When you hear him say back?（你是一般疑问句还是对划线部分提问？）

Did you know when would he come back?

at which time 改成 at what time 或者 when.
he's come back 改成 he would be back
Did you hear him say when he'd be back?

Have you heard him saying when he would be back?
hear 和 say 两个动词不能连用.at which time很别扭,也不常用,应该用when
