["

was thought crashing; searched

","

was thought to crash; searching

","

was thought to have crashed; searching

","

[["C"]]

考查不定式和非谓语动词。句意：科学家们使用声纳绘制了被认为是飞机坠毁地点的海底地图，寻找飞机残骸。sb. be thought to do sth. 是固定短语，意为 “某人被认为做某事”，由 “used” 可知，时态是一般过去时，crash的动作已经发生，因此不定式用完成式，主语plane是单数，因此第一空是was thought to have crashed；句中谓语是used，第二空用非谓语动词，Scientists和search之间是主谓关系，因此第二空用现在分词表主动，作状语。故选C。
