Answer 1

C

試題分析: 反義疑問句一般遵循前肯定則后否定，前否定則后肯定，疑問部分時(shí)態(tài)，人稱要與前文保持一致。Very few非常少，表達(dá)的是否定含義，故反問部分用肯定形式，根據(jù)passed可知反問部分助動(dòng)詞用過去時(shí)態(tài)，選C。
點(diǎn)評(píng)：本題關(guān)鍵點(diǎn)在于對(duì)前文時(shí)態(tài)的判斷，判斷時(shí)態(tài)有多種方法，如時(shí)間詞，上下文語(yǔ)境等，本題就是憑借時(shí)間詞before判斷出前文為完成時(shí)態(tài)，平時(shí)需加強(qiáng)練習(xí)。
