参考答案

正确答案：C
解析：本句意思是“一些政府官员滥用权力和职责获取非法钱财的事情被曝光了。”employ意为“使用(方法、材料)等”，如：The police had to employ force to break up the crowd．警察不得不使用武力驱散人群。take“拿走”，如：I passed him the rope and he took it．我递给他绳子，他接住了。abuse“滥用”，最符合题意，如：He abused his position as a mayor to give jobs to his relatives．作为市长他滥用职权给亲戚安排工作。overlook“未注意到”，如：They overlooked the enormous risks involved．他们忽略了暗含的巨大危险。
