Question

正确形式填空They(spend)all their money,so they have to walk home.

能统一下答案么

Answer 1

They【have spent 】all their money,so they have to walk home.
用现在完成时，表示 “花光了所有的钱”对现在造成了影响，即 “他们不得不步行回家”。

祝你开心。

Answer 2

用have spent
如果只是个过去式的话，那么后面的have to 就要写成 had to
有因有果嘛~ 就这个道理

Answer 3

They spent (过去式)all their moeny ,so they have to walk home.
