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。

Sports shoes that out whether their owner has enough exercise to warrant time in front of the television have been devised in the UK.

The shoes—named Square Eyes—contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.

The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”

Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.

Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.

Existing pedometers （计步器） normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”

According to Swan, the purpose of her design project is to ________.

A．keep a record of the steps of the wearer

B．deal with overweight among teenagers

C．enable children to resist the temptation of TV

D．prevent children from being tricked by TV programs

D．The way of changing steps into TV watching time.

Compared with other similar products, the new design ________.

A．makes it difficult for lazy teenagers to cheat

B．counts the wearer’s steps through shaking

C．records the sudden movement of the wearer

D．sends teenagers’ health data to the receiver
