Question

【題目】Not until recently _______the development of tourist-related activities in the rural areas.

A. had they encouraged B. they had encouraged

C. they encouraged D. did they encourage

Answer 1

【答案】D

【解析】考查部分倒裝。句意：直到最近他們才鼓勵(lì)在農(nóng)村地區(qū)開展與旅游業(yè)有關(guān)的活動(dòng)。not until位于句子開頭句子用部分倒裝，部分倒裝即只把謂語(yǔ)的一部分（如助動(dòng)詞、情態(tài)動(dòng)詞等）放到主語(yǔ)前，或把句子的強(qiáng)調(diào)成分提前。根據(jù)句意可知用一般過(guò)去時(shí)態(tài)，故D正確。
