37、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”

39、hake Shack 的收益状况却很好。前一分句中的 struggling 和后一分句中的“doing well”均为延续性动作，因此，引导时间状语从句 “McDonalds is struggling.back”的从属连词可以填 As/While/When。9【答案】 successful 考查词性转换。IPO 是 Initial Public Offerings 的缩写，指公司的股票首次公开上市，作为专有名词使用，因此此处应用 success的形容词形式修饰 IPO。故填 successful。10【答案】 On 考查介词。表示在具体的某一天应用介词 on。.短文改错假定英语课上老师要求同
