单选题________ confidence in yo

单选题 ________ confidence in yourself is the biggest barrier _______ greater progress in your work.A.Lacking of; to makingB.Lack of; to makeC.Lack of; to makingD.The lack of; to make

C解析试题分析：考查固定句型，Lack of意思“缺乏”，be barrier to意思“是……障碍”，句子意思“缺乏自信心是在工作上取得较大进步的最大障碍”，所以选C考点：考查固定句型点评：Lack of意思“缺乏”，名词词性，Lack of+n= Lacking+n，confidence in yourself意思“自信心”， be barrier to意思“是……障碍”， to是介词，后跟名词或动名词，固定句型要靠平时多积累。
