问题 First designated in 1970, Earth Day has become an annual international event ______ concerns about environmental issues such as pollution.
选项 A、dedicated to raising
B、dedicated raising
C、dedicates to raise
D、that dedicates to raising
答案A
解析 考查dedicate的用法。dedicate是及物动词，其固定搭配为dedicate oneself/one’s life to sth.，意为“献身于，致力于……”。选项A用过去分词形式dedicated作后置定语，修饰event，可还原成定语从句为：which is dedicated to raising，因此为正确答案。由此也知选项D中dedicates不能为主动态。
