问题 The discussion was so prolonged and exhausting that ________ the speakers stopped for refreshments.A. at large B. at intervals C. at ease D. at random

选项 A. at large
B. at intervals
C. at ease
D. at random

答案 B

解析 因为这个讨论是prolonged and exhausting 的,prolonged and exhausting就表达了作者的态度,所以空格处填入的词语应该是一中性词。答案是B,at intervals(时不时地)。At large“详细的”;at ease“自由自在地”;at random“胡乱地”。
