上海合作组织是第一个以中国城市命名的国际组织，它鼓励成员国在政治、经济、文化、环保和其他领域的有效合作，进一步加强了中国与俄罗斯、哈萨克斯坦等周边国家的联系。上海合作成立18年来，逐渐形成了“互信、互利、平等、协商、尊重多样文明、谋求共同发展”的“上海精神”。2019年6月14目，上海合作组织成员国元首理事会第十九次会议在吉尔古斯斯坦首都比什凯克行。国家主席习.平在会上发表重要讲话，强调要从“上海精神”中发掘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   1   to describe the invisible yet poisonous mixture of gases and particles(颗粒) clinging(依附) to smokers' hair and   2  , not to mention cushions and carpeting, that stays long after second-hand smoke has cleared from a room. The remaining   3  heavy metals, carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in,   4  if they're crawling or playing on the floor。 Doctors from MassGeneral Hospital for Children in Boston coined the term "third-hand smoke" to   5  these chemicals in a new study that   6  on the risks they pose to infants and children. The study was published in the  7  issue of the journal Pediatrics。 "Everyone knows that second-hand smoke is bad,  8  they 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 are   9  the 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 and   10  , and they think it's okay because the second-hand smoke isn't getting to their  11  . We needed a term to describe these tobacco toxins that aren't  12  ." The study reported on  13  toward smoking in 1,500 households across the United States. It found that the vast majority of both smokers and nonsmokers were   14  that second-hand smoke is harmful to children. Some 95 percent of nonsmokers and 84 percent of smokers  15  with the statement that "inhaling smoke from a parent's cigarette can   16  the health of infants and children"。 But   17  fewer of those surveyed were aware of the  18  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   19  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  20  , which researchers interpreted as acknowledgement of the risks of third-hand smoke。 (    ) 1.
