Answer 1

The develop contries of the world are using up valuable resources at a rate (unprecedented human history).請問括弧中哪裡有錯?英文裡沒有 develop countries, 只有developed countries (已開發國家)和developing countries (開發中國家).
unprecedented human history 中間需要加個in, 文法才對這樣說會比較好:The developed countries of the world are using up valuable resources at a rate unprecedented in human history.(世界上已開發國家正以有史以來最高的耗用量在消耗寶貴的資源)當然囉, developed countries 換成 developing countries 也可以.
