The remaining3heavy metals, carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in,4if they're crawling or playing on the floor。Doctors from MassGeneral Hospital for Children in Boston coined the term third-hand smoke to5these chemicals in a new study that6on the risks they pose to infants and children. The study was published in the7issue of the journal Pediatrics。Everyone knows that second-hand smoke is bad,8they don't know about this, said Dr. Jonathan P. Winickoff, the lead author of the study and an assistant professor of pediatrics at Harvard Medical School。When their kids are9the house, they might smoke. Or they smoke in the car. Or they strap(用带子捆扎) the kid in the car seat in the back and crack the window and10, and they think it's okay because the second-hand smoke isn't getting to their11.

CBAAD ABABD CABDB ACBBA解析本文通过一项研究说明了人们陌生而又熟悉的三手烟对儿童的影响。解此完形填空的时候要注意把作者的思路逻辑和生活常识紧密结合，并注重联系上下文的语境逻辑。1. C 考查动词过去分词的含义辨析及在语言逻辑方面的准确应用。联系上下文的语境及日常生活中的常识,我们容易推理出这一句的语境是：所谓“三手烟”是用来指房间内的“二手烟”清除许久之后，仍残留在坐垫、地毯甚或吸烟者头发和衣物上看不见的气体和颗粒的有毒混合物。我们不难看出此处应该填上表示被用来之意的动词过去分词，也即是C项，而其余ABD项依次分别所表达的意思是：讲述，讨论，提及，这些词语所表示的意思都和这儿的语言逻辑不相吻合，故我们选择C项为最佳

这个解释是对的
