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
relative threat to children’s health that isn’t as easy to get rid of:【M1】______
third-hand smoke. That’s the term being used to describe the
invisible yet toxic mixture of gas and particles clinging to【M2】______
smokers’ hair and clothing, not mention cushions and carpeting,【M3】______
that linger long after second-hand smoke has cleared from a room.【M4】______
The reminder includes heavy metals and radioactive materials that【M5】______
young children can get on their hands and ingest, 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 latest issue of the journal【M6】______
Pediatrics. "Everyone knows that second-hand smoke is bad, but
they don’t know about this," said Dr. Jonathan P. Winickoff, the
leaded author of the study and an assistant professor of【M7】______
pediatrics at Harvard Medical School. "When your kids are out of【M8】______
the house, they might smoke. Or they smoke in the car. Or they
strap the kid in the car seat in the back and crack the window and
smoke, and they think it’s okay so the second-hand smoke isn’t【M9】______
getting to their kids," Dr. Winickoff continued. "We needed a term
to describe these tobacco toxins that aren’t invisible."【M10】______
【M2】
选项
答案
gas—gases
解析
语法错误。由于上文用到了mixture一词,表示“混合物”,由此可知这里的gas应该是指“各种各样的气体”,当表示这个含义时,gas是可数名词,应该改成复数形式。
