因为完全没有光，而且承受着比在地球表面大数百倍极大压力，深海底部对人类而言是一个充满敌意环境，在一些方面就像外层空间一样险恶和遥远。
分句1：Totally without light and subjected to intense pressures
分句2：hundreds of times greater than at the Earth’s surface
分句3：the deep—ocean bottom is a hostile environment to humans
分句4：in some ways as forbidding and remote as the void of outer space

分句1是分句3状语
分句3是整个长句子主句
分句4是分句3后置定语，修饰分句3a hostile environment to humans
