場(chǎng)景：好的 今天就把健身納入日常

例句：Regular exercise is the cornerstone of our daily life on the grounds not just of the body fitness but also of the brain-changing benefits.

詞：ground

英英釋義：a reason for what you say or do, or for being allowed to say or do something

“ground”作名詞有很多意思，除了最常見(jiàn)的“地面”外，它也常被用于表示“理由”“根據(jù)”。掌握了 ground 的這個(gè)用法，我們就可以在很多場(chǎng)景下，用它替換 reason，because 等，讓表達(dá)具有多樣性。

ground 表示“理由”時(shí)，一定要注意：它一般都會(huì)以復(fù)數(shù)形式 grounds 出現(xiàn)。

? ? 我們常說(shuō)的“實(shí)錘”（即“確鑿的證據(jù)”）就可以用到 ground。比如一位女性指控他人性騷擾，如果有確鑿的證據(jù)的話，我們就可以說(shuō)：

1. She has valid grounds for accusing him of sexual harassment.

? ? “基因編輯嬰兒”曝光后引來(lái)了許多爭(zhēng)議，許多人從倫理層面批評(píng)這個(gè)項(xiàng)目。我們可以用英文說(shuō)成：

2. Gene editing has drawn widespread public criticism on ethical grounds.

ground 常和介詞 on 搭配構(gòu)成短語(yǔ) on the grounds of/that， 表示“因?yàn)椤睦碛伞薄耙浴瓰楦鶕?jù)”。我們?cè)谡撟C說(shuō)理時(shí)就可以用到它，如果你準(zhǔn)備考雅思和托福，一定要掌握它。

? ? 《經(jīng)濟(jì)學(xué)人》在介紹西湖大學(xué)時(shí)，提到現(xiàn)任校長(zhǎng)施一公的教學(xué)理念時(shí)就用到了 on the grounds that：

3. Mr Shi believes that if elite universities select students on the grounds not just of their test scores, but also of their intellectual maturity and social responsibility, this will influence the way pupils are taught at school, and change the way they think.
