问答题

【正确答案】I

【答案解析】本空应填形容词。由系动词feel可知，本空应填形容词。but表明，此处为转折关系，故所填词应与love意思相对，故答案为I项guilty。feel guilty about...意为“对……感到内疚”。

问答题

【正确答案】N

【答案解析】本空应填副词，因此从M项seemingly和N项strangely中选择。根据该句中的but：可知，前后句子之间是转折关系，故答案为N项strangely，这也符合下文所说的那种矛盾情节。

问答题

【正确答案】J

【答案解析】本空应填动词。分析文章可知，前四句说的都是一般的事实，因此本句时态为一般现在时。本句主语为the answer，所以所填词为动词的第三人称单数形式，故从A项benefits和J项lies中选择。另外，该动词应能与in连用，故答案为J项lies。lie in意为“在于”。

问答题

【正确答案】L

【答案解析】本空应填动词。分析句子结构可知，本空应填现在分词，构成分词短语作句子的状语，且该词还应该能与for连用，可从C项competing和L项searching中选择。compete for意为“为……而竞争”，search for意为“寻找”。结合文意可知，答案为L项searching。

问答题

【正确答案】K

【答案解析】本空应填名词。由空前的a可知，此处应填单数名词。分析句子结构可知，空格后面的内容是对所填词进行解释说明，因此所填词应与forbid同义，故答案为K项prohibition。

问答题

【正确答案】D

【答案解析】本空应填动词。根据be和by确定应填过去分词，故应从D项defined和H项granted中选择。再根据上下文，上文表示“入乡随俗意味着跟‘真正的美国人’吃一样的东西”，下文通过but转折，表示“美国的食物已经被诸如比萨和热狗这样的外来品所______了”，故答案为D项defined，即被诸如比萨和热狗这样的外来品所诠释了。grant意为“准予；承认”，与文意不符，故可排除。

问答题

【正确答案】O

【答案解析】本空应填名词。所填词应能与come as no连用，根据空格后的句意“无论是在波士顿倾茶事件中，还是在南方午餐柜台前的静坐抗议活动中，食物都曾被这个国家当作界定斗争的媒介”可知，答案为O项surprise。come as no surprise意为“不足为奇”。

问答题

【正确答案】F

【答案解析】本空应填形容词。分析句意可知，whether引导的从句是真正的主语，本句表达出于宗教原因戒酒和由于政治避难而戒肉对健康和道德观念的重要性，故答案为F项essential。

问答题

【正确答案】B

【答案解析】本空应填名词。所填名词作brought的宾语。空格后面句子的含义是美国人对于他们所吃的食物的态度是矛盾的，故空格所在句也应表示一种不确定性，句子中已经有了否定词not，所以本空应填表示肯定意义的词，答案为B项certainty。句意为“坚定的立场并不是确定不变的”。

问答题

【正确答案】E

【答案解析】本空应填形容词。分析句子结构可知，所填词应该能和后面的介词of连用，再根据前面一句中的矛盾情节和后面的句意“特别是当他们更清楚地了解了食物的成分时”可推知，答案为E项doubtful。句意为“他们对自己的食物产生了怀疑”。
