| 释义 | 〔periodic〕Periodic has long been used loosely to mean "occasional, intermittent,” but this usage may be confusing for readers who are accustomed to using the word only in its narrower sense of "at regular or predictable intervals.”Thus the writer who saidParker's losses at the track were not covered by his periodic winners invited the (most likely unintended) inference that Parker had a system that enabled him to pick winners at regular intervals. Substitution ofoccasional in this context would have resolved the ambiguity. Periodic 长时间以来不严谨地用于指“时常的，偶而的”， 但这个用法常常使那些习惯于将这个词用于“在有规律或可预测的间歇内”这个狭窄词义的读者迷惑。因此写帕克在赛跑中的失败不如他的胜利多 这句话的作者（主要是无意中）造成帕克有在定期赢得比赛的方法的推论。 在上下文中用occasional 代替应该能解决这种模棱两可的问题 |
