對於這句我有兩條問題

Sorry, you cannot change this sentence if you're a fan of John Lennon and his song "imagine".

"as one" is an idiomatic expression, meaning "in agreement", "all together", "united".

中文 字面上翻譯:

The world will be as one. 世界將團結一致

The world will live as one. 世人將生活為一體

as one world means (travelling all over) the world.

The world will be as one. 的中文是：世界將被變成一個

改成 The world will be one的話，那你的文法（grammar)就會錯了
