His writing style, characterized by simplicity and understatement, influenced modern fiction, as 11 his life of adventure.
答案：(C) did
as did his life of adventure 是「as + 助動詞 + 主詞」的倒裝結構，did 代替前面的動詞 influenced，避免重複：他充滿冒險的一生同樣也影響了現代小說；was、being、doing 都無法擔任這個代動詞。
句子讀到 as，你等著看一個完整的子句，結果後面只有一個 did 加一串名詞，會覺得動詞不見了。於是你想把空格填成看起來像動詞的 being 或 doing，把它補成「正在做」的樣子。動詞其實沒有不見——did 就是那個動詞，它代替前面出現過的 influenced，避免同一個字說兩次。
讀英文句子，先抓兩樣東西：誰、怎麼了——主詞與動詞。這兩樣定了，其餘都是掛在上面的修飾語。先把句子切開看：[His writing style], characterized by simplicity and understatement, [influenced] modern fiction, as ___ [his life of adventure]. 方括號裡依序是主詞、主要動詞，以及 as 後面那個新的主詞；中間被兩個逗號夾住的是修飾語，遮掉不影響句子成立。接著看 as 後面：主詞是 his life of adventure，那它的動詞在哪裡？被 did 頂替了。驗算只有一步——把 did 還原成它代替的那一串，整句讀成 as his life of adventure influenced modern fiction（他充滿冒險的一生同樣影響了現代小說），句子站得住，方向就對了。這背後是英文避免重複的習慣：同一個動詞不重說第二次，改用一個助動詞頂替。你國中就用過 So do I.、Neither have I.，只是當時記的是整組說法，沒特別去想那個 do 或 have 在頂替什麼；這裡把它拆開看，did 頂的是 influenced modern fiction 一整串。還有一點順手分清楚。國中那組 So have I. 的倒裝是強制的，寫成 So I have. 就錯了；本句的 as did his life of adventure 是選擇性的，寫成 as his life of adventure did 一樣正確。本句選前者，是因為英文習慣把長的成分留到句尾——主詞 his life of adventure 比助動詞長得多，助動詞先出來，句子的重量才落在後面。兩種倒裝長得像，規則不同，別把國中那條「一定要倒裝」直接套過來。
三個選項的錯法各不相同，值得分開記。was 錯在「代錯種類」：代動詞要跟它代替的動詞同一類，前面是 influenced 這個一般動詞，就得用 do 的家族；要用 was，前面得是 be 動詞才行，例如 His style was simple, as was his life.（他的風格簡潔，他的人生也是。）being 與 doing 的問題相同：兩個都是分詞、沒有時態，當不了子句的動詞，而 as 引導的是一個有主詞的子句，需要一個有時態的動詞來搭配。分不出來時回到最基本的一條——一個子句有且只有一組主詞與動詞，這一格要填的就是 his life of adventure 的那個動詞。
as did ／ as does + 主詞（…也是如此，比較子句的倒裝）、as was ／ as were + 主詞（前面是 be 動詞時用）、so do I（我也是）、neither do I（我也不）、be characterized by（以…為特色）、understatement（含蓄、輕描淡寫）。
Ernest Hemingway (1899-1961) was an American author and journalist. His writing style, characterized by simplicity and understatement, influenced modern fiction, as 11 his life of adventure.
Hemingway started his career as a journalist at 17. In the 1920s, he was sent to Europe as a newspaper correspondent to 12 such events as the Greek Revolution. During this period, he produced his early important works, including The Sun Also Rises. Among his later works, the most outstanding is The Old Man and the Sea (1952), which became perhaps his most famous book, finally winning him the Pulitzer Prize he had long been 13 .
Hemingway liked to portray soldiers, hunters, bullfighters—tough, at times primitive people whose courage and honesty are set against the brutal ways of modern society, and who in this 14 lose hope and faith. His straightforward prose is particularly effective in his short stories, some of 15 are collected in Men Without Women (1927). In 1954, Hemingway was awarded the Nobel Prize in Literature. He died in Idaho in 1961.
