Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting（借用）my daughter's experience.
分析主干：I had to accept the fact…
Because引导原因状语从句。该从句用了know little about…结构，about 有两个宾语。that 引导的从句是即farm animals 和angels，中间用or 连接，两个名词分别都有定语从句加以修饰。主句部分fact 带有that 引导的同位语从句。
译文：因为我对会使用工具的家畜和上一年级的天使一无所知，所以我得承认这样的事实：我在借用我女儿的经验。
