26．He stared at the empty bottle for a while, feeling happy that he had sent the butterfly back ________ it belonged—nature.
A. to which B. that
C. which D. to where
[解析]本题考查名词性从句引导词。句意：他盯着空瓶子看了一会儿，为他把蝴蝶放回了它应在的地方——大自然而感到高兴。send back to“把……送回”，belong 为不及物动词，若接宾语则需用 belong to。分析结构可知，此处 where it belonged 作 send back to 中介词 to 的宾语从句，where 在从句中作地点状语，故D项正确。
[答案]D
