D,将来完成时,By the time this talk is over 当谈话结束的时候,注意这里is,表示将来,所以主句也应该是将来时态,根据句意用将来完成时.意思为：当谈论结束的时候,我们对地球知道了很多.这里主要还是根据句意来判断.
如理解不对望改正.

D
By the time this talk is over 意味着这是过去时
所以AB都是进行时，可以排除。
C是将来时，而D是将来完成时。
只有D符合。
句子大意为：当谈论结束的时候，我们将学到很多关于地球的知识。

个人觉得选D，首先，A是不对的，be 加动词ing表示正在发生的动作，不对，同理B也不对。
C和D比较，D的意思是我们应该已经学到很多关于地球的内容了，所以选D
