答案：kept working for eight hours，why don't you/Why not stop to have a rest？．
首先通过中英文句子的比对，可知英文句子中缺少"连续工作8个小时了，为什么不停下来休息一下呢？"的表达．短语"连续做某事"的英文表达是：keep doing sth..本题中，时间状语"八个小时"用for eight hours，表示动作的持续性用现在完成时，现在完成时的构成是：主语+have/has+动词的过去分词；句式"为什么不做某事呢？"是Why don't you 或Why not，短语"停下来休息一下"是stop to have a rest 故答案为：kept working for eight hours，why don't you/Why not stop to have a rest？
