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 21    to describe the invisible yet poisonous mixture of gases and particles(颗粒) clinging （依附）to smokers' hair and 22    , not to mention cushions and carpeting, that stays long after second-hand smoke has cleared from a room. The remaining  23   heavy metals, carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take  in, 24  if they're crawling or playing on the floor。

　　Doctors from MassGeneral Hospital for Children in Boston coined the term "third-hand smoke" to 25 these chemicals in a new study that 26    on the risks they pose to infants and children. The study was published in the  27    issue of the journal Pediatrics。

　　"Everyone knows that second-hand smoke is bad, 28   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 29  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 30   , and they think it's okay because the second-hand smoke isn't getting to their 31   . We needed a term to describe these tobacco toxins that aren't 32   ."

　　The study reported on 33   toward smoking in 1,500 households across the United States. It found that the vast majority of both smokers and nonsmokers were 34   that second-hand smoke is harmful to children. Some 95 percent of nonsmokers and 84 percent of smokers 35  with the statement that "inhaling smoke from a parent's cigarette can 36    the health of infants and children"。

　　But 37   fewer of those surveyed were aware of the  38   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 39  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 40   , which researchers interpreted as acknowledgement of the risks of third-hand smoke.

A cat then? Usually if you disturbed a cat, it ran off and jumped, and you heard or noticed something else. By doing a lot of night work, you learned to notice these things, but now all riders noticed was the silence which had followed the rustling sound. So he acted cautiously. He did not flash his torch about the houses near the comer but walked on, and, a little way from the spot where he had heard the sound, stopped and bent his head, as if he was lighting a cigarette. A policeman who stopped to light a cigarette seemed the most unsuspicious policeman in the world.

There was still no sound. There were bushes in the garden of the house where Rider had first heard it and he knew that a man could hide there out of sight. But if he went back, it would ware any such man. So instead he stood and shone his torch at the window nearest him, and as if he had noticed something unusual, he walked towards it and opened the wooden gate, which made no sound at all. He reached the entrance and shone the torch on the keyhole of the front door and as he did so, the rustle came again, this time much more softly. He looked round quickly.

　　  1. What was Constable Rider doing on this very cold evening?

　　　　   A. He was looking for anything out of the ordinary.

　　    B. He was looking for something that had been lost.

　　　　   C. He was being careful not to disturb people.

　　　　   D. He was being careless in carrying on these duties.

　　  2. When he heard the rustling sound, he

　　　　   A. thought that it was probably caused by some animal

　　 B. knew that he had disturbed a cat

　　　　   C. thought that it was caused by the wind

　　　　   D. realized that he had turned a comer

　　  3. As he then heard no more sounds, Rider decided

　　　　   A. that he had been mistaken, and walked on

　　　　   B. that he might as well have a cigarette

　　　　   C. to flash his lamp on a window near the comer

　　　　  D. not to show that he had noticed anything

　　  4. Why did Constable Rider not go right back to the house on the comer?

　　　　   A. He had seen a man hiding there.

　　　　   B. He didn't want to use his torch.

　　　　   C. It would show that he had noticed something.

Is there anything more important than health? I don’t think so. “Health is the greatest wealth(财富),” wise people say. You can’t be good at your studies or work well when you are ill.　　     
Speaking about health, I can’t help telling you a funny story.　　
An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease.　   
He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat at pleasure, drink with measure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day.　　
A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.　　
“But you know, doctor,” he said, “it’s not easy to begin smoking at my age.”
【小题1】The writer thinks that 　　　　.

Susan Williams went to a boarding（寄膳宿）school. Here is one of the letters she wrote to her parents from the school.

Dear Mom and Dad，

I’m afraid I have some very bad news for you. I have been very naughty and the school headmaster is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.

The trouble started last night when I was smoking a cigarette in bed. This is against the rules, of course. We are not supposed to smoke at all.

As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste­paper basket, which caught fire. There was a curtain near the waste­paper basket which caught fire, too. Soon the whole room was burning. The headmaster phoned for the fire department. The school is a long way from the town and by the time the firefighters arrived, the whole school was in flames. Many of the girls are in the hospital.

The headmaster says that the fire was all my fault and you must pay for the damage. She will send you a bill for about a million dollars.

I am very sorry about this.

Much love, Susan.

P. S. None of the above is true, but I have failed my exams, I just want you to know how bad things could have been！
