解析：
B 选项：文章开篇提到美国关于酒精的辩论升温，B 选项 “这场辩论聚焦于酒精对健康的影响以及新的指南”，作为主题句，概括了文章围绕的核心内容，引出下文对该辩论各方面的阐述，故 1 选 B。
E 选项：此段讲美国年轻人饮酒习惯的转变，E 选项 “他们更常选择无酒精鸡尾酒，并且认为酒精有害”，具体说明了年轻人的这些变化，与后文引用皮尤研究中心的数据相呼应，故 2 选 E。
F 选项：前文阐述了年轻人对酒精看法的改变，F 选项 “年轻人态度的改变是整体趋势的一部分”，起到承上启下的作用，既总结了年轻人态度的变化，又引出下文整体消费趋势的内容，故 3 选 F。
A 选项：上文说美国人均纯酒精消费量下降，A 选项 “这种下降伴随着无酒精市场的增长”，进一步说明消费变化与无酒精市场的关系，与后文提到的无酒精市场年复合增长率相衔接，故 4 选 A。
G 选项：最后一段提到酒业的游说以及政治人物的态度，G 选项 “酒精辩论的政治方面也不容忽视”，可作为该段主题句，引出下文关于政治方面对酒精辩论影响的内容，故 5 选 G。
干扰项分析：
C 选项：“酒业试图影响新的消费指南”，虽然与文章内容相关，但主要出现在文章关于不同立场对新指南影响的部分，单独作为一个段落主题句过于片面，且与上下文衔接不如 G 选项紧密，所以是干扰项。
D 选项：“但在不同时期对酒精危害的认知有所不同”，文章重点并非强调不同时期对酒精危害认知的差异，与文章整体逻辑联系不紧密，因此是干扰项。
Passage 2: Why Are Our Feet Different Sizes
The human body is often assumed to be symmetrical, but this isn't always true, especially when it comes to our feet. (1)____. Understanding the reasons behind this can help us better deal with the issue.
Research has consistently shown that few people have feet that are exactly the same in size or shape. (2)____. A 1983 study in the US and a 2018 study in the UK both support this. In fact, a significant percentage of people in different countries have feet with a size difference of more than 4 millimeters.
There's no clear - cut answer as to which foot is usually larger. (3)____. Some studies suggest the left foot is more often larger, while others indicate the right foot has a higher chance. This variance is part of normal human body variation.
However, there are other factors contributing to foot size differences. (4)____. For example, pregnancy in women can cause such changes due to ligamentous laxity. Birth conditions like club foot can also lead to significant size differences between the feet.
Injuries, especially during childhood, can play a role. (5)____. Prolonged use of a cast can weaken and shrink foot muscles. Also, uneven use of feet, like in ballet dancers, can increase muscle mass in one foot.
In most cases, different - sized feet are just a nuisance. But there are ways to find shoes that fit, such as buying shoes for the larger foot and using custom devices or buying shoes in two different sizes.
A. Different studies have come to different conclusions.
B. This is a common phenomenon that has various causes.
C. This shows that foot size differences are widespread.
D. One factor is related to physical conditions and activities.
E. Wearing a cast on the foot can have a negative impact.
F. The feet are an example where this lack of symmetry is obvious.
G. The difference in foot size can also be influenced by injuries.
答案：
F
C
A
D
G
解析：
F 选项：文章开头提到人体并非总是对称，尤其是脚。F 选项 “脚就是这种不对称现象明显的一个例子”，承接上文，引出下文对脚大小不同原因的讨论，作为第一段的结尾合适，故 1 选 F。
C 选项：第二段讲述多项研究表明很少有人双脚大小形状完全相同，C 选项 “这表明脚大小的差异很普遍”，总结上文研究结果，与前后文衔接紧密，故 2 选 C。
A 选项：第三段论述关于哪只脚通常更大没有明确答案，A 选项 “不同的研究得出了不同的结论”，很好地概括了该段内容，故 3 选 A。
D 选项：第四段说还有其他因素导致脚大小不同，D 选项 “一个因素与身体状况和活动有关”，引出下文关于怀孕、先天疾病等因素的阐述，故 4 选 D。
G 选项：第五段开头提到受伤会影响脚的大小，G 选项 “脚大小的差异也会受到受伤的影响”，与段落主旨相符，引出下文受伤影响脚大小的具体情况，故 5 选 G。
干扰项分析：
B 选项：“这是一种有多种原因的常见现象”，表述较为笼统，相比其他选项，没有针对各段具体内容进行有效衔接，所以是干扰项。
E 选项：“在脚上打石膏会有负面影响”，只提及了受伤后打石膏这一个方面，过于片面，不能作为段落主题句引出下文关于受伤影响脚大小的多种情况，因此是干扰项。
Passage 3: Why Do Animals Drink Alcohol
The idea that alcohol consumption is a uniquely human behavior is being challenged. (1)____. There is growing evidence suggesting that many animals might be consuming ethanol regularly.
Research on animal alcohol consumption is still in its early stage. (2)____. Many reports are just anecdotes, like the stories of drunk moose or elephants. But the lack of documented cases may be due to insufficient research rather than the rarity of the behavior.
Despite the limited research, scientific interest in this topic is rising. (3)____. For example, wild chimpanzees are known to consume fermented palm sap, and spider monkeys have ethanol metabolites in their urine after eating fermented fruits.
However, numerous questions remain. (4)____. We need to understand the availability of ethanol in the environment and whether certain species seek it out. Only then can we explore why animals consume ethanol.
There are several hypotheses about the reasons. (5)____. It could also be beneficial, like using fermentation odors to find food or for medicinal purposes. And for some, it might have a cognitive effect similar to that in humans.
A. We need to study more about the environment and animal behavior.
B. Some say it could be an unintended result of a fruit - based diet.
C. Scientists are now finding more about animals' alcohol intake.
D. But much of the information is not scientifically validated.
E. The view that only humans drink alcohol may not be correct.
F. More research is needed to answer these questions.
G. Some documented cases of wild primates consuming ethanol exist.
答案：
E
D
G
A
B
解析：
E 选项：文章开头表明饮酒是人类独有的行为这一观点正被挑战，E 选项 “只有人类饮酒的观点可能不正确”，作为主题句，引出下文关于动物也可能饮酒的论述，故 1 选 E。
D 选项：此段讲动物饮酒研究处于早期阶段，D 选项 “但很多信息都没有经过科学验证”，与前文 “很多报告只是传闻” 相呼应，进一步说明研究现状，故 2 选 D。
G 选项：上文说科学界对该话题兴趣上升，G 选项 “存在一些野生灵长类动物摄入乙醇的记录案例”，举例说明兴趣上升的表现，与后文黑猩猩和蜘蛛猴的例子相承接，故 3 选 G。
A 选项：第四段说很多问题有待解决，A 选项 “我们需要更多地研究环境和动物行为”，指出了解环境中乙醇分布及动物是否寻找乙醇等问题需要对环境和动物行为进行研究，符合段落主旨，故 4 选 A。
B 选项：最后一段讲关于动物饮酒原因的假设，B 选项 “有人说这可能是以水果为主食的意外结果”，是假设之一，与后文其他假设并列，故 5 选 B。
干扰项分析：
C 选项：“科学家现在正在发现更多关于动物酒精摄入的情况”，表述较为宽泛，没有针对各段具体内容进行有效衔接，不能准确概括段落或起到过渡作用，所以是干扰项。
F 选项：“需要更多研究来回答这些问题”，虽然有一定相关性，但相比 A 选项，没有具体指出研究方向，与上下文的逻辑联系不够紧密，因此是干扰项。
