题目解答
答案
D. caused
解析
步骤 1:分析句子结构
句子的主语是 "Medical accidents",谓语是 "have attracted",宾语是 "much attention"。"in that country" 是地点状语。"______ by drugs" 是修饰 "Medical accidents" 的定语。
步骤 2:确定定语的类型
根据句子结构,"______ by drugs" 是一个非谓语动词短语,用来修饰 "Medical accidents"。由于 "Medical accidents" 和 "cause" 之间是被动关系,所以应该使用过去分词 "caused"。
