Ernest Hemingway (1899-1961) was an American author and journalist. His
writing style, characterized by simplicity and understatement, influenced
modern fiction, as_______his life of adventure.
(A) was (B) being (C) did (D) doing
解答為C 理由是did代替前面的influcenced
我想問為什麼可以判斷did出是代替 influened 而不是 characterized 呢
是因為這句話接在influencedmodern fiction的後面嗎
還是從文意上判斷出來的呢

characterized by simplicity and understatement只是一個形容詞片語，用來修飾his writing style。這句話的動詞是influenced

簡單判斷的話就是前後有兩個逗號，可以把他當作是中文的括號，所以只是修飾／解釋（可有可無的意思）結構就如樓上大大說的，主要子句的動詞落在influenced，後面as自然會接動詞也就是助動詞did
