英语长难句解析，求大神帮助
Probably there is no one here who has not in the course of the day had occasion to set in motion a complex train of reasoning of the very same kind,though differing in degree,as that which a scientific man goes through in tracing the causes of natural phenomena. 句子的结构，分析

1. in course of 在……的过程中,在……中 如：The new textbook is in course ofpreparation.新教科书正在准备之中。 in the course of = during 在……期间，在……的时候 如：He has seen many changes in the course of his long life.他在漫长的一生中目睹了许许多多的变化。 The company will face major challenges in the course of the next few years.这家公司以后几年将面临重大的挑战。 所以这里的in the course of day 就直接理解为：一天之中 （这是一个很装的用法，我们写作的时候不能用） I Strove with none,for none was worth my strife.
2. occasion 时候，时机
3. set in motion + sth 短语：发起…，着手做…
4. a train of 一系列的，一连串的
5. scientific man 科学家
【主干识别】there is no one here 【其他成分】 who has not in the course of the day had occasion to set in motion a complex train of reasoning 定语从句的主干
【难点】1） of the very same kind as that 定语从句中的定语修饰 reasoning (That 指代reasoning) （2） though differing in degree 定语从句中的定语也修饰reasoning ，前后两个定语补全是这样的： （1）reasoning differing （that which a scientific man goesthrough in tracing the causes of natural phenomena） in degree. （2） reasoning ofthe very same kind as that which a scientific man goes through in tracing the causes of natural phenomena. 根据两个定语的语义在加上一个though（虽然）. 接下来： which a scientific man goes through in tracing the causes of natural phenomena.定语从句修饰that ；其中 in tracing the causes of natural phenomena 为状语。
【参考译文】世上大概不会有人一整天都没有机会进行一连串复杂的思考活动，而这些思考活动与科学家在探索自然现象原因时所经历的思考活动，尽管复杂程度不同，但在类型上是完全一样的。 世上大概不会有人一整天都没有机会进行一连串复杂的思考活动，这些思考活动与科学家在探索自然现象原因时所经历的思考活动，在类型上是完全一样的，尽管复杂程度是不同的。
