C．when

D．where

Answer 1

C

試題分析：句意：我正在我的臥室寫作業(yè)，突然這時(shí)等滅了，我點(diǎn)了一支蠟燭做的作業(yè)。while “在......期間”，表示一段時(shí)間，引導(dǎo)的狀語(yǔ)從句的謂語(yǔ)動(dòng)詞是持續(xù)性動(dòng)詞；when “在這時(shí)”，表示時(shí)間點(diǎn)，引導(dǎo)的狀語(yǔ)從句的謂語(yǔ)動(dòng)詞是持續(xù)性動(dòng)詞或瞬間性動(dòng)詞。go out 是瞬間性動(dòng)詞，所以此處用when 來(lái)引導(dǎo)句子。故選C。
