In effect， in trying to demonstrate that the imagination is more profound and less submissive to the intellect than Saint-Beuve assumed， Proust elicited vital memories of his own and， finding subtle connections between them， began to amass the material for Remembrance.

译文：事实上，为了试图证明想象力要比Saint-Beuve的假设来得更为深刻，且并非那么易于屈服于理性，Proust引发了他自己的至关重要的记忆，发现它们之间不无微妙的联系，便开始为Remembrance收集材料。

解释：该句是考察复杂修饰和插入语的。句首是表目的的状语从句：in trying to demonstrate that the imagination is more profound and less submissive to the intellect than Saint-Beuve assumed。然后是finding引导的插入语隔断了前面连接句子的and的后半部分，影响了考生对整句的把握。

解法：看到句首是介词短语引导的状语从句，就先直接往后找句子主语，找到主语之后，直接跳过出现成对逗号的插入语往后看完整的句子。最后，再回头看插入语部分的补充信息对句子整体进行进一步的理解。
