Question

分析一下这个英语句子的结构

Valuable amounts of minerals exist on the ocean floor ready to be mined (开采).
请问一下这里为什么用ready，好像也不是非谓语，求高手指点

Answer 1

ready to be mined 是后置定语，修饰valuable amounts of minerals.
可以翻译为 海洋上存在很多待开采的矿物。如改为 There exist valuable amounts of minerals ready to be mined. 就容易理解了。

Answer 2

句子的主干结构是minerals exist on the ocean floor.
minerals 有两个定语修饰，前面的是valuable amounts of
后面的ready to be mined 可以理解定语从句which is to be mines的简略, 其中which is省略了

Answer 3

ready to be mined 是用来修饰minerals的，如果把句子改成Valuable amounts of minerals which are ready to be mined exist on the ocean floor .是不是更能理解一点。
