1.Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface，the deep—ocean bottom is a hostile environment to humans，in some ways as forbidding and remote as the void of outer space.
(定语后置in some ways…)
由于完全没有光，而且承受着比在地球表面大数百倍的极大压力，深海底部对人类而言是一个充满敌意的环境，在某些方面就像外层空间一样险恶和遥远。
Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface 原因状语
the deep—ocean bottom is a hostile environment to humans 主句
in some ways as forbidding and remote as the void of outer space 后置定语，修饰a hostile environment to humans
整个句子结构是：
原因状语+主句+后置定语
