【命題依據(jù)】高考試題每年都要涉及句法知識(shí)，這些特殊的句型結(jié)構(gòu)，每年單項(xiàng)填空題都會(huì)出現(xiàn)1-2道。高考試題對(duì)這些句型結(jié)構(gòu)的考查往往是以測(cè)試它們中的特殊結(jié)構(gòu)為主，例如倒裝句中否定副詞位于句首；as引導(dǎo)讓步狀語(yǔ)從句的倒裝；省略if的虛擬條件句等。又如強(qiáng)調(diào)句中的強(qiáng)調(diào)特殊疑問句以及強(qiáng)調(diào)句與其它相似句式的混合使用等。估計(jì)今后高考試題不會(huì)降低對(duì)這些特殊句型結(jié)構(gòu)的考查力度。

【答案解析】由于答句中used to 前否定副詞的使用，說(shuō)明該句陳述部分為否定結(jié)構(gòu)，后面反意疑問部分要用肯定結(jié)構(gòu)形式，故首先排除選項(xiàng)A、C。選項(xiàng)B的助動(dòng)詞不一致，應(yīng)選用did或 used 來(lái)構(gòu)成反意疑問句。答案為D。
