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 (消費(fèi)) .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 (尸體解剖) 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 (被動(dòng)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(支氣管炎) 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.

Answer 1

1.B主旨大意題�？v觀全文可知本文主要講述了吸煙和孩子健康之間的關(guān)系，吸煙對孩子的危害非常大。

2. D細(xì)節(jié)理解題。由最后一段的“Studies have shown that children (especially infants) of parents who smoke have more lung illnesses,such as bronchitis(支氣管炎) and pneumonia,and can develop asthma(哮喘) . ”可知，應(yīng)是 lung illnesses 而不是 lung cancer。

3. B細(xì)節(jié)理解題。本句的意思是“年輕時(shí)養(yǎng)成的吸煙^慣可能會(huì)使人一生都離不開香煙”。A、C和D太絕對，故選B.
