A、aimed
B、targeted
C、designated
D、designed
答案
B
解析
本题考查动词辨析。空格处填入的动词的过去分词形式与to搭配作句子的状语,其中some是所填分词的逻辑主语,它指代前面的sleep-related research,逻辑宾语是specific disorders。target(以……为目标)放入原文,表达的含义为“一些与睡眠相关的研究以特定的(睡眠)紊乱为目标”。故为正确答案。aim(at)“瞄准,以……为目标”不与to搭配;designate“指派,选定”,与逻辑主语不搭配;design“计划,设计”,与宾语不搭配,它的常见用法是be designed to do sth.。
