As the economy picks up,opportunities will abound for aspiring leaders.时间状从
As any biolographer knows,a person's early life and its conditions are often the greatest gift to an individual.非限定性定从修饰句子
第二个as引导定从,实际是any biographer knows as,引出后面。
那第一个句子the economy picks up不可以是the economy picks up as作定从吗?
虽然好像看句意第一个做状语比较合理,可是我好像被介宾从句搞混乱了,pick up 后面不是也可以接宾语?
