Doctors believe that secondhand smoke may cause lung cancer in people who do not smoke. Nonsmokers often breathe in the smoke from other people’s cigarettes. This is secondhand smoke. The U.S. Environmental Protection Agency reports that about fifty-three thousand people die in America each year as a result of exposure to secondhand smoke.
The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals harm a nonsmoker’s health. Recently, though, scientists expressed their opinion after they studied a large group of nonsmokers. They discovered that even nonsmokers had unhealthy amounts of these toxic chemicals in their bodies. As a matter of fact, almost all of us breathe tobacco smoke at times, whether we realize it or not. For example, we cannot avoid secondhand smoke in restaurants, hotels, and other public places. Even though many public places have nonsmoking areas, smoke flows in from the areas where smoking is permitted.
It is even harder for children to avoid secondhand smoke. In America, nine million children under the age of five live in homes with at least one smoker. Research shows that these children are sick more often than the children who live in homes where no one smokes. The damaging effects of secondhand smoke on children also continue as they grow up. The children of smokers are more than twice as likely to develop lung cancer when they are adults as the children of nonsmokers. The risk is even higher for the children who live in homes where both parents smoke.

第1题:
1.推理判断题。题干要求推断美国53,000人死亡的原因。根据关键词fifty-three thousand定位到文章第一段最后一句，这些人的死因是由于exposure to secondhand smoke，即“暴露于二手烟中”，由此可以推断死亡者本人不抽烟，故B项“尽管他们不吸烟”正确。而A项“由于吸烟”和C项“因为他们的父母吸烟”明显错误；D选项“尽管他们的父母不抽烟”属于过度推断。因此本题正确答案为B项。
第2题:
2.细节事实题。根据题干Non-smokers可定位到原文第二段第四句，再根据下一句...almost all of us breathe tobacco smoke at times, whether we realize it or not可知，不管我们有没有意识到，我们几乎都吸入烟草的烟，所以非吸烟者身体受损的原因是“因为他们吸入有毒的烟”，故A项正确。B选项原文没有提及，C选项与第二段最后一句不符，故排除；D选项根据第二段第三句“甚至非吸烟者身体内有过量的这些化学物质”可以排除。
第3题:
3.细节事实题。题干要求找出错误选项。A选项“非吸烟者也许会被动吸入二手烟”，根据常识可判断正确；根据第一段最后一句可知非吸烟者可能死于二手烟，所以B选项“有些非吸烟者可能因为吸二手烟而死于肺癌”正确；根据第二段 almost all of us breathe tobacco smoke at times, whether we realize it or not可知，C选项“我们都多多少少遭受二手烟的痛苦”正确；D选项“二手烟比抽烟本身伤害更大”在原文中并未提及，属于无中生有。因此本题答案为D项。
第4题:
4.细节事实题。题干要求判断四个选项中哪一个不是二手烟对孩子的消极影响。根据题干定位至原文最后一段。由these children are sick more often than the children who live in homes where no one smokes可知，这些孩子比家里没有人吸烟的更容易生病，故A选项正确，可排除；B选项“他们更可能患心理疾病”在原文中并未提及。根据原文倒数第三句可知，C选项“孩子们长大了也会受二手烟的影响”正确，可排除。根据原文最后一句“父母吸烟的孩子长大后患肺癌的概率是父母不吸烟的孩子的两倍多”可知，D选项“他们更容易患肺癌”正确， 可排除。故本题正确答案为B。
第5题:
5.推理判断题。题干要求判断以下哪种孩子受二手烟的伤害最大。根据关键词children定位至最后一段可知，“父母都抽烟的孩子患肺癌的风险更高”。A选项为“5岁以下生活在无人抽烟的家庭的孩子”；B选项为“5岁以下生活在父亲或母亲一方抽烟的家庭的孩子”；C选项为“5岁以下生活在父母都抽烟的家庭的孩子”；D选项“5岁以下不和父母一起生活的孩子”。因此，本题正确答案为C项。
