35、解析 空格前说“允许赚合理的利润”，而空格后却说“限制无理涨价的行为”，语义存在转折。因此选B。A.harmfulB.beneficialC.excellentD.qualified解析：解析 空格前的bans(禁止)，提示空格应填入负面意义的词，harmful“有害的”符合要求。beneficial“有益的”；excellent“优秀的”；qualified“合格的”。A.facultyB.quantityC.qualityD.qualification解析：解析 此处意为“要求食品_达标”，比较四个选项，quality“质量”代入空格，句意通顺。faculty“才能；能力”；quantit

45、上工作)，这跟正常的情况是相反的，因此选reversed“颠倒的”。former“以前的”；returned“归来的，被送回来的”；regular“定期的”。A.sleepingB.eatingC.sportingD.thinking解析：解析 空格后说“晚上工作”，那对应的是“白天睡觉”，因此选sleeping“睡觉”。A.ThereforeB.UnfortunatelyC.In a wordD.In comparison解析：解析 上文提到“适应颠倒的睡眠和清醒时间常需要五天到一周”，而空格后却说“企业每周换班一次”，前后的语义存在转折，因此选Unfortunately“不幸的是”。Therefore“因此”；In a word“总而言之”；In comparison“比较起来”。A.conveysB.meansC.illustratesD.interprets解析：解析 This指代的是上一句的“企业一般每周换班一次”，空格后说“刚刚适应一种生活规律时又不得不转换成另一种”，这是对上一句的解释，因此选B项means“意味着”。
