4. burn the oil midnight oil Everybody knows it is not healthy to burn the midnight oil. Sometimes we have no choice to stay up cramming for the tests tomorrow.虽然每个人都知道熬夜是不健康的。但有时我们还是不得不熬夜抱佛脚。
注解：(1) 短语：have no choice 别无选择;不得已 cram for为.....临时抱佛脚。 (2) 语法：cramming for the tests tomorrow是现在分词短语在句中作原因状语。(3) 短语来源： Burn the midnight oil这个短语是引用十七世纪英国诗人Francis Quarles相当受欢迎的作品《徽章》(Emblems)。当时人民想在夜晚读书或工作，只能使用油灯照明，因此这位诗人就在他深夜埋头工作时，有感而发的写下：“We spend our midday sweat, our midnight oil/ we tire the night in thought, the day in oil.” 表示自己在白天或深夜都得燃烧油灯，汗流工作。 后来当某人日以继夜地工作时，我们就会说他“连半夜也要燃烧油灯”，慢慢地这种说法也就被用来指“开夜车”“熬夜”的意思。
