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.

Rome-Doctors and medical groups around the world last weekend reacted with strong opposition to the news that an Italian specialist is on the point of cloning the first human baby．　　

Dr．Severino Antinori, who is the head of a hospital in Rome, has been referred to in an Arab newspaper as claiming that one of his patients is eight weeks pregnant （怀孕的）with a cloned baby．　　

Antinori refused to comment on the reports, but in March 2001 he said he hoped to produce a cloned embryo （卵）for implantation within two years．So far seven different kinds of mammals have already successfully cloned, including sheep, cats and most recently rabbits．　　

Doctors showed their doubt and were strongly opposed although they admit that human cloning would finally come true unless there was a world wide ban on the practice．　　

Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology said: “I find it astonishing that people do this where the result can be foretold that it will not be a normal baby．It is using humans as guinea pigs．It makes people feel sick．” But Ronald Green, director of the Ethics institute at Darmouth College in the US, said it is unlikely that an eight-week-old pregnancy would lead to a birth．　　

So far all cloned animals have suffered from some different serious disorders, many of them dying soon after their births ．　　

Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one．　　

“There are no benefits of cloned human beings, just harm,”said Dr．Michael Wilks of the UK．

45．What is the doctors’ general attitude to cloning of humans according to the passage?

A．They are against it．                    B．They support it．

C．They welcome it．                          D．They pay no attention to it．

46．Which of the following statements is true according to the passage?

　  A．Doctor Severino Antinori is strongly opposed to cloning human beings．

　  B．Up to now, seven kinds of animals have been cloned, including sheep, cats, humans and rabbits．

　  C．Professor Rudolf Jaenisch is carrying on an experiment on cloning an eight-week-old embryo．

　  D．Ronald Green doubts about the future successful birth of the so-called cloned embryo．

47．Which is the best title for the passage?

　  A．The Success of Cloning Humans           B．The Anger at Cloning Humans
