Shack悄然走红的现象并分析了原因。1【答案】choosing考查非谓语动词。句意：观察者们说，当选择去哪里吃，吃什么的时候，美国人想要更多的选择和新鲜的食物。分析句子结构可知，choose与其逻辑主语Americans之间构成主动关系，应用现在分词形式。故填choosing。2【答案】restaurants考查名词复数。“one of名词复数”是固定结构，意为“之一”。故填restaurants。3【答案】but考查并列连词。句意：麦当劳是美国乃至全世界最著名的餐厅之一，但是，近来公司领导者们却看到了一些他们可能不会喜欢的数字。两个句子之间为转折关系，故用but。4【答案】eighth考查序数词。由空格前的定冠词the可知，此处应用所给词的序数词形式。the eighth month意为“第八个月”，符合语境。故填eighth。5【答案】working考查动词的时态。句意：麦当劳正努力地想把顾客吸引回来。由“助动词be现在分词”构成现在进行时，表示现阶段正在进行的动作。故填working。6【答案】to reach考查不定式作宾语。want to do sth.意为“想要做某事”，为固定搭配。故填to reach。7【答案】a考查冠词。a new kind of意为“一种新的”。因为上文没有提到Shake Shack这种新式餐馆，此处是第一次提到，故用不定冠词a表示泛指。8【答案】As/While/When考查从属连词。句意：正当麦当劳努力地挽回顾客时，Shake Shack的收益状况却很好。
