If you are listening to that 5th grade English teacher correct your grammar while you are trying to capture a fleeting (稍縱即逝的) thought, the thought will die. (07.6 Passage 2)
分析主干:the thought will die
本句的難點在從句部分。If 引導條件狀語從句,從句用了listen to sb. do sth.結構,省略to 的不定式correct 作補語;that 5th grade English teacher 用了借喻的修辭手法,指代你心中的那個“批判性思維”。while 引導的時間狀語從句修飾are listening。
