Question

【題目】It was in the early 1990s that cartoons began to take off in China, ________ there were only picture-story books.

A. where B. when C. after that D. before which

Answer 1

【答案】D

【解析】考查介詞和定語從句。句意：在90年代早期卡通片開始在中國盛行，在此之前中國只有圖畫書。先行詞為the early 1990s，表示在此之前用介詞before，關系詞代指the early 1990s，故用which，故選D。
