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 1 to discuss 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 Mass General Hospital for Children in Boston used 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 settle the kid in the car seat in the back and 10 the window and smoke, 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(毒素)that aren't 12 ."
The study reported on 13 towards 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 conscious of the 18 of third-hand smoke.Since the term is so new, the researchers asked people if they 19 the statement that "breathing air in a room 20 where people smoked yesterday can harm the health of infants and children".
Only 65 percent of nonsmokers and 43 percent of smokers answered yes.
As my wife greeted me one evening, her voice came through the door,“Guess what?”
I always take a deep 1 on this very leading question.“What?”I asked.
“I just won a sales contest at work and the 2 is dinner for two at the new fancy restaurant down by the river-front!”
She was so 3 .We knew the restaurant was extremely good.“See?I told you there would be a 4 for me to wear my new spring outfit,”she shyly reminded me.
“ 5 can play at that game,”I responded.“I will wear my gray suit, my Borsalino imported straw hat and a new silk tie.We will be well 6 .”
It was early 7 and nearing dusk as the waiter took us to a table by a window, with a(n) 8 of the river.And the table was 9 set, with a smoke-gray tablecloth and bright colored napkins.
A delicious meal 10 in such an atmosphere should be remembered a long time.As it 11 , this will probably never be forgotten.
As the shadows lengthened, the 12 rocking by the riverbank, I murmured,“Why not take a walk?”
Hand in hand, we walked by the stores.People smiled and nodded.“I 13 realized there were so many 14 people as we have seen this evening, dear,”I observed.
“Probably your new straw hat or your 15 ,”she said.
After receiving many smiles, we 16 ourselves back at the restaurant, looking at ourselves in the 17 .It was then that I saw the 18 for all the smiles.
Caught in the fly of my trousers and 19 down for all to see was a bright red 20 from the restaurant!
When I was a little girl, every Sunday my family of six would put on our best clothes and go to Sunday School and then church.The 1 in elementary school would all meet together to sing songs, and then later divide into 2 based on their ages.
One Easter Sunday, all the kids 3 with big eyes and big 4 about what the Easter Bunny(复活节小兔)had brought. 5 all of the kids shared their stories with 6 , one young boy , whom I shall call Bobby, sat 7 .One of the teachers , noticing this, said to him, “And what did the Easter Bunny 8 you?”He replied, “My mom 9 the door by accident so the Easter Bunny couldn't get 10 because he hadn't got a key.”
This sounded like a 11 idea to all of us kids, so we kept on going with the stories.My mom knew the true story, 12 .Bobby's mom was a single parent , and she suspected(怀疑)that they just couldn't 13 the Easter Bunny.
After Sunday School was over, everyone went off to 14 .But my mom announced that we were going home 15 .At home, she explained that to make Bobby feel 16 , we were going to pretend(假装)to be the Easter Bunny , make a basket of our candies for him and 17 it at church.We all donated(捐赠)some to the basket, and 18 back to church.There, mom hung the basket over the hanger(挂钩)and attached(附上)a(n) 19 :
Dear Bobby,
I'm sorry I 20 your house last night.Happy Easter.
