(1)本句是一个主从复合句，主句的主干是he asserted that (his power was very limited)，还有两个that引导的宾语从句、一个for引导的原因状语从句，。
(2)主句所含的宾语从句中，主干是his power was very limited; to follow a long and purely abstract train of thought是不定式作后置定语修饰his power。
(3)for引导的原因(状语)中所含的宾语从句是he never could have succeeded with mathematics，由于太长，将其放在宾补certain之后。
