Parents who smoke often open a window or turn on a fan to clear the air for their children, but experts now have identified a related threat to children’s health that isn’t as easy to get rid of: third-hand smoke. That’s the term being used to describe the invisible yet poisonous gases and particles clinging (粘着) to smokers’ hair and clothing, not to mention cushions and carpeting, that stays long after second-hand smoke has cleared from a room. The remains include heavy metals and radioactive materials that young children can get on their hands and take into their body, especially if they’re crawling or playing on the floor.
Doctors from MassGeneral Hospital for Children in Boston coined the term "third-hand smoke" to describe these chemicals in a new study that focused on the risks they pose to infants and children. The study was published in the latest issue of the journal Pediatrics. "Everyone knows that second-hand smoke is bad, but they don’t know about this," said Dr. Jonathan P. Winickoff, the lead author of the study and an assistant professor of pediatrics (儿科) at Harvard Medical School. "When their kids are out of the house, they might smoke. Or in the car, they put the kid in the car seat in the back and crack the window and smoke, and they think it’s OK because the second-hand smoke isn’t getting to their kids. We needed a term to describe these tobacco toxins that aren’t visible."
The study reported on attitudes toward smoking in 1,500 households across the United States. It found that the vast majority of both smokers and nonsmokers were aware that second-hand smoke is harmful to children. Some 95 percent of nonsmokers and 84 percent of smokers agreed with the statement that "inhaling smoke from a parent’s cigarette can harm the health of infants and children". But far fewer of those surveyed were aware of the risks of third-hand smoke. Since the term is so new, the researchers asked people if they agreed with the statement that "breathing air in a room today where people smoked yesterday can harm the health of infants and children". Only 65 percent of nonsmokers and 43 percent of smokers agreed with that statement, which researchers interpreted as acknowledgement of the risks of third-hand smoke.
According to the passage, third-hand smoke refers to_____.
选项
A、the damage to the third person’s health caused by smoking
B、the parts of cigarette that are thrown away by the smokers
C、the unseen poisonous stuff left over indoor by smoking
D、poisonous materials that can be seen and found on the carpeting
答案
C
解析
根据题干中的third-hand smoke将本题出处定位到首段第二句。由该句可知,“三手烟”是指房间内的“二手烟”清除许久之后,仍残留于坐垫、地毯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。[C]中的unseen poisonous stuff对应该句invisible yet poisonous gases and particles:leftover indoor对应该句clinging to smokers’ hair and clothing…cushions and carpeting,故答案为[C]。[A]是对third-hand smoke字面意思的曲解。[B]是对该句中的particles所设的干扰项。[D]只是说留在地毯上的有毒物质,没有明确说明是由吸烟引起的。
