Question

AHA Scientific Position found cigarette smoking by children and teenagers in theUnited Statesis a major public health problem.

If not controlled,later in life it will become a major risk factor for coronary heart disease (冠心病) ，which leads to heart attack. Among young men and women— who are otherwise at very low risk of developing coronary heart disease—cigarette smoking may cause as many as 75 per cent of the cases of coronary heart disease. The longer a person smokes,the higher the risk of coronary heart disease. More than 80，000 people die each year from coronary heart disease caused by smoking.

Most adult smokers started when they were teenagers;smoking habits in youth seem to determine lifetime cigarette consumption (消费) .丁here’s also evidence that those who begin smoking before they’re 20 have the highest incidence and earliest onset of coronary heart disease and high blood pressure. Autopsy (尸体解剖) studies of smokers have raised questions about the effects of smoking in childhood and ado-lescence(青春期) on the development of fatty build-ups in arteries in adulthood.

What about passive (被动的) or second-hand smoking? About 59 per cent of American children aged between 4 and 11 are suffering from second-hand smoke at home. Studies have shown that children (especially infants) of parents who smoke have more lung illnesses,such as bronchitis(支气管炎) and pneumonia,and can develop asthma(哮喘) . And because smoking parents are more likely to cough and spread germs,their children are more likely to develop chest illnesses. Exposure to tobacco smoke also increases the risk of heart disease.

1.B主旨大意题。纵观全文可知本文主要讲述了吸烟和孩子健康之间的关系，吸烟对孩子的危害非常大。

2. D细节理解题。由最后一段的“Studies have shown that children (especially infants) of parents who smoke have more lung illnesses,such as bronchitis(支气管炎) and pneumonia,and can develop asthma(哮喘) . ”可知，应是 lung illnesses 而不是 lung cancer。

3. B细节理解题。本句的意思是“年轻时养成的吸烟^惯可能会使人一生都离不开香烟”。A、C和D太绝对，故选B.
