46. What do chain smokers think of cigarette packaging?
- A. Fancy packaging can help to engage new smokers.
- B. It has little to do with the quality or taste of cigarettes.
- C. Plain packaging discourages non-smokers from taking up smoking.
- D. It has little impact on their decision whether or not to quit smoking.
答案：D
答案句：Any veteran nicotine addict will testify that fancy packaging plays no role in the decision to keep smoking.
参考译文：任何老资格的尼古丁成瘾者都会证实，精美的包装在决定是否继续吸烟方面不起任何作用。
定位线索：题干“chain smokers”→答案句“veteran nicotine addict”；文中“plays no role in the decision to keep smoking”对应选项D“has little impact on their decision whether or not to quit smoking”。
解析：题干问老烟民对香烟包装的看法，答案句直接指出包装在继续吸烟的决定中不起作用，即对戒烟决定影响很小，对应D项。A项“帮助吸引新烟民”、C项“阻止非烟民吸烟”均与老烟民观点无关，B项“与质量或味道无关”文中未提及，属于无中生有。
47. What has the UK government agreed to do concerning tobacco packaging?
- A. Pass a law to standardise cigarette packaging.
- B. Rid cigarette cartons of all advertisements.
- C. Subsidise companies to adopt plain packaging.
- D. Reclassify cigarettes according to packaging.
答案：A
答案句：But that isn't why the government--under pressure from cancer charities, health workers and the Labour party--has agreed to legislate for standardised packaging. … Plain packaging would be another step in the reclassification of cigarettes from inviting consumer products to narcotics (麻醉剂).
参考译文：但这并不是政府——在癌症慈善机构、卫生工作者和工党的压力下——同意立法规范包装的原因。……平装将是香烟从诱人的消费品重新归类为麻醉剂的又一步。
定位线索：题干“UK government agreed to do”→答案句“agreed to legislate for standardised packaging”；文中“reclassification of cigarettes”对应选项D“Reclassify cigarettes according to packaging”。
解析：题干问政府同意做什么，答案句明确说政府同意立法规范包装，且平装是重新归类香烟的一步，对应D项。A项“通过法律规范包装”是政府行为本身，但题目问的是“concerning tobacco packaging”的具体内容，D项更准确；B项“去除所有广告”文中未提，C项“补贴公司”无中生有。
49. Why has it taken so long for the UK government to consider plain packaging?
- A. Prime Minister Cameron has been reluctant to take action.
- B. There is strong opposition from veteran nicotine addicts.
- C. Many Members of Parliament are addicted to smoking.
- D. Pressure from tobacco manufacturers remains strong.
答案：A
答案句：But strength of will is the missing ingredient where Mr. Cameron and public health are concerned. His attitude to state intervention has looked confused ever since his bizarre 2006 lament (叹惜) that chocolate oranges placed seductively at supermarket checkouts fueled obesity.
参考译文：但在卡梅伦先生和公共卫生方面，意志力是缺失的因素。自2006年他奇怪地叹惜超市收银台诱人摆放的巧克力橙导致肥胖以来，他对国家干预的态度一直显得混乱。
定位线索：题干“why it has taken so long”→答案句“strength of will is the missing ingredient”；文中“Mr. Cameron”对应选项A“Prime Minister Cameron has been reluctant to take action”。
解析：题干问为何拖延这么久，答案句指出卡梅伦缺乏意志力，态度混乱，暗示他犹豫不决，对应A项。B项“老烟民反对”文中未提，C项“议员吸烟”无中生有，D项“烟草制造商压力”虽提及但非主要原因，且答案句强调卡梅伦个人因素。
