选项 A、stay up
B、crop up
C、fill up
D、cover up
答案B
解析 本题考查考生对固定词组搭配和短语含义的掌握。英语短语的牢固掌握、准确理解及灵活运用一直是英语考查的一个重．最，它们短小、形象、鲜活，所以在英语交流中被广泛使用，在阅读理解、翻译和写作中也有重要作用。所以动词词组的掌握是英语学习的重要组成部分，本题中选项[A] stay up“熬夜，不睡觉”，选项[B]crop up“突然出现，涌现”，选项[C]fill up“充满，填满”和选项[D] cover up“覆盖住，掩盖”都是不同动词和介词up的固定搭配。而根据上下文含义，当墨西哥城由于极度恐慌而几近瘫痪后，在纽约市、美国西南部和世界其他国家应该是出现了更多病例，所以选项[B]crop up“突然出现，涌现”为正确答案。
