问题     Third-hand smoke is tobacco smoke contamination that lingers in carpets, clothes and other materials hours or even days after a cigarette is put out. According to a study, a large number of people, particularly smokers, have no idea that third-hand smoke is a health hazard for people. Of the 1,500 smokers and nonsmokers surveyed, the vast majority agreed that second-hand smoke is dangerous. But when asked whether they agreed with the statement, "Breathing air in a room today where people smoked yesterday can harm your health," only 65% of nonsmokers and 43% of smokers answered "yes."
选项
答案 所谓“三手烟”是指在香烟被熄灭的数小时甚至几天后，仍残留于地毯、衣服和其他物品上的烟雾等污染物。一项研究表明，很多人，尤其是烟民，并不知道“三手烟”会危害人体健康。在参与调查的1500名受访者(烟民及非烟民)中，大部分都知道“二手烟”对健康的危害。但是当被问及是否同意“昨天有人抽过烟的屋子里的空气会危害人们的健康”时，只有65%的非烟民和43%的烟民认同该说法。
