声明：120长难句版权归北京新东方所有，以下解析内容是个人作为爱好者所作。
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．
main idea: the deep-ocean bottom is a hostile environment to humans——海底对于人类是一个险恶的环境
sub1: totally without light and subjected to intense pressures—— 在描述deep-ocean bottom，没有光的同时压力还很大
sub2: hundreds of times greater than at the Earth's surface——在描述sub1中的pressure，具体说一下压力有多大
sub3 : in some ways as forbidding and remote as the void of outer space——这句话我已开始看的时候真是懵逼了，重点要抓出来as forbidding and remote as the void of outuer space中的as.....as.....这个结构，就像外太空那样险恶和虚无（不要在意void，这个词就是作者在装逼而已）
2.Basic to any understanding of Canada in the 20 years after the Second World War is the country's impressive population growth．
这是一个简单句，就是倒装了一下，正过来就是 The country's impressive population growth is basic to any understanding of Canada in the 20 years after the WWII.
3.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．
main idea: 个人第一眼看这个句子的时候大概就看出了意思是“吃有机食物比较健康这种说法已经广为人知”，如果读者也能看懂大意的话也没必要细扣成分
sub1: claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health——说了一种claims，一种什么什么观点
sub2: have become widely publicized and form the basis for folklore——上边那个claims已经广为人知并且成为了一些民间说法folklore的基础
4.There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones，that fertilized eggs are nutritionally superior to unfertilized eggs，that untreated grains are better than fumigated grains and the like．
main idea: 我认为要理解这句话一定要理解一个核心词----unsubstantiated，adj.未经证实的，这句话说的是 unsubstantiated reports, 后面那一堆都是这个reports的观点，大意就是自然地，有机的都比人工处理过的，不自然的好
这句话就不再具体分析了，记几个词汇吧，fertilized eggs 受精的蛋, unfertilized eggs未受精的蛋，fumigated,经过烟熏消毒过的
