【題目】Only when class began ______ that he had left his book at home.

A. will he realizeB. he did realize

C. did he realizeD. should he realize

【答案】C

【解析】

考查倒裝結(jié)構(gòu)。當(dāng)only等詞謂語句首時(shí)，主句采用部分倒裝，句意：直到上課開始時(shí)，他才意識(shí)到他已經(jīng)把書丟在家里面了。結(jié)合語境可知此處描述的是過去的動(dòng)作，故用過去時(shí)態(tài)，助動(dòng)詞用did，故選C。
