3. 第一道题就是语法，是考can 与could.记得是说用飞行器探测某星球的地质环境，the result can't be certain except that the aerocraft can take back something.(大意是这样的，这个是我的答案）
有选项是
1) couldn't be certain except that the aerocraft can take back
something.
2) can't be certain except that the aerocraft could take back something.
3) couldn't be certain except that the aerocraft could take back
something.

我认为你的选择是对的。因为句子是陈述一件事情，所以前后的 can 时态一致. 题中并没有其他状语从句暗示the aerocraft 不能带回something，而需要用虚拟语气。(Personal view.)//"
