共享题干题（一）Cigars Instead?请根据短文的内容，回答问题。Smoking one or two cigars a day doubles the risk of cancers of the lip, tongue, mouth, and throat, according to a government study.Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx (voice-box) six-fold, say researchers at the National Cancer Institute in Bethesda, Maryland.In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers.The health effects of smoking cigars is one of eight sections of the article Cigars: Health Effects and Trends. The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines.This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country, said Dr. Richard Klausner,director of the National Cancer Institute, in a statement.The data are clear -- the harmful substances and carcinogens in cigar smoke, like cigarettes, are associated with the increased risks of several kinds of cancers as well as heart and lung diseases, he added. In other words, cigars are not safe alternatives to cigarettes and may be addictive.To those individuals who may be thinking about smoking cigars, our advice is -- dont. To those currently smoking cigars, quitting is the only way to eliminate completely the cancer, heart and lung disease risks, warned Klausner.According to National Cancer Institute press release, there havent been any studies on the health effects on nonsmokers at cigar social events, but ...a significant body of evidence clearly demonstrates and increased lung cancer risk from secondhand smoke.1.[不定向选择题]What is the main idea of the article Cigars: Health Effects and Trends?A.When it comes to cancer, cigars are not any safer than cigarette B.Cigars may be addictive while cigarettes are not easily C.Cigars contain less harmful substances than cigarette D.Increase in cigar-smbking does not affect public health muc 2.[不定向选择题]According to the report, smoking three or four cigars a day __________.A.increases the risk of oral cancer for non-smoker B.greatly increases the risk of oral cancer for smoker C.increases the risk of more than one cancer for non-smoker D.greatly increases the risk of more than one cancer for smoker

1.参考答案：A
参考解析：文章主旨题。倒数第三段中的一句话概括了文章的中心，即“…cigars are not safe alternatives to cigarettes and may be addictive．”选项A意思与之相符。因此本题的正确答案为A选项。?
2.参考答案：D
参考解析：细节题。题目问的是：根据这个报告，每天抽三到四根雪茄，会怎么样?根据题干信息词three or four cigars定位到第三段：“smoking three or four cigars a day increased the risk of oral cancer to 8．5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk ofnonsmokers．”。对比分析原文和题目，原文谈论了吸烟者患癌症的可能性(与不吸烟者相比分别增加到8．5倍和4倍)。也就说，他会很大程度上增加患癌症的风险，D选项说greatlyincreasestheriskofmorethanone cancer与原文表达的意思相符，所以本题答案为D选项。?3.[不定向选择题]In the context of this passage, secondhand smoke may mean __________.A.Smoking bad-quality cigar B.Smoking very cheap cigar C.being near cigar smokers when they are not smoking D.being near cigar smokers when they are smoking
