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.
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。
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2修饰分句1结尾的短语intense pressures，
分句1是分句3的原因状语
分句3是整个长句子的主句
分句4是分句3的后置定语，修饰分句3的a hostile environment to humans
整个句子结构是：
原因状语+主句+后置定语
这是主句前后分别有状语和定语的修饰成分，但是本句其实不是复合句。句子的核心意思是深海对于人类
而言是一个充满敌意的环境。
接下来跟着小编一起来看一下第二个例子：
2.As a result，claims that eating a diet consisting entirely of
organically grown foods prevents or cures disease or provides other
benefits to health have become widely publicized and form the basis
for folklore.
(同位语从句claims that…)

分句1： that eating a diet consisting entirely of organically grown
foods prevents or cures disease or provides other benefits to health
分句2：claims have become widely publicized and form the basis for
