I hope her come back in a month.这个句子对不对？

I hope her come back in a month 是错误的。

I hope she will come back in a month.正确。

应该是I hope she will come back in a month.
因为此句为一般将来时
句式为:主语+will+V原
而I hope her come back in a month．中没有一般将来时的结构，所以有语法错误，不正确．

是I hope she will come back in a month.
I hope后面加一个完整的句子,其实完整的句子是I hope that she will come back in a month省略了that,she并不是直接接在hope动词后面,所以不要变宾格

要I hope that she will come back in a month.才正确。（不信问你的老师，我上初一才刚刚学这个，所以很确定。）人称前加that

in a month 好象错了

in a month is wrong
