专八改错原题:Stemmed from the theoretical perspective of constructivism, discovery learning is believed to be a tool for facilitating the creation and organization of knowledge.
答案将stemmed 改为主动的stemming。
请教老师,有无be stemmed from 或be originated from 这种说法?此出用主动和被动有何区别?谢谢!
stem from是不及物动词stem+介词构成的及物短语动词,后接的名词是介词from的宾语。只要from后接有宾语,stem就是主动意义,所以要用现在分词作状语。例如词典例句:His love of the outdoors stems from his father. 所以,用过去分词作状语是错误的。
