非常感谢你帮我搬这个箱子,英语怎么说?

Thanks a lot for helping me carry the box
这句话我们老师刚刚讲过

显然，"Thanks a lot for helping me carry the box."这句话比另外一句好多了，而且那一句好象还有语法问题.

Thanks a lot for helping me carry the box.

Thank you very much for helping me carry the box.

Thanks a lot for your helping me to carry the box.

Thank you very much for me to move this box
