2. 为什么选这个词？ 

“ground”作名词有很多意思，除了最常见的“地面”外，它也常被用于表示“理由”“根据”。掌握了 ground 的这个用法，我们就可以在很多场景下，用它替换 reason，because 等，让表达具有多样性。 

ground 表示“理由”时，一定要注意：它一般都会以复数形式 grounds 出现。 

我们常说的“实锤”（即“确凿的证据”）就可以用到 ground。比如一位女性指控他人性骚扰，如果有确凿的证据的话，我们就可以说：She has valid grounds for accusing him of sexual harassment.

“基因编辑婴儿”曝光后引来了许多争议，许多人从伦理层面批评这个项目。我们可以用英文说成：Genome editing has drawn widespread public criticism on ethical grounds.

ground 常和介词 on 搭配构成短语on the grounds of/that， 表示“因为…的理由”“以…为根据”。我们在论证说理时就可以用到它，如果你准备考雅思和托福，一定要掌握它。
