英语语法结构Probably there is not one here who has not in the cour

Probably there is not one here who has not in the course of the day had occasion to set in motion a complex train of reasoning..请问这个IN MOTION 怎么在 a complex train of reasoning前面
(1) Probably there is not one here who has not had occasion
大概,或许,这里每个人都有机会
(2) to set in motion a complex train of reasoning in the course of the day
在一天的时间中开始一套复杂的推理训练
set in motion 规定词组搭配（1） set in motion sth (2) set sth/sb in motion
意思：开始,调动；把…发动起来
句子意思：或许/很可能,在一天时间当中,这里每个人都有开始一套复杂的推理训练的机会.

set in motion 是个固定词语，set sb/sth in motion,不能分开，主谓宾结构，所以a complex train of reasoning在后面啦。 请采纳。
