一箭双雕 to kill two birds with one stone
　　趁热打铁 to strike while the iron is hot
　　火上加油 to pour oil on the flame
　　晴天霹雳 like a bolt from the blue
　　浑水摸鱼 to fish in the troubled water
　　轻如鸿毛 as light as a feather
　　空中楼阁 castle in the air
　　破釜沉舟 to burn the boat
　　如履薄冰 to be on the thin ice
　　
　　然而，英汉民族毕竟在地理环境、生活习俗、宗教信仰等方面存在相当的差异，所以，成语的产生和使用在两种文化中表现出各自不同的特色。例如，有些成语意思相近，但是使用的比喻形象有差别：
　　
　　守口如瓶 as dumb as an oyster; as silent as the graves; as close as wax
　　一贫如洗 as poor as a Church mouse
　　健壮如牛 as strong as a horse
　　血流如注 to bleed like a pig
　　 to wake a sleeping dog 打草惊蛇
　　 to cast pearls before swine 对牛弹琴
　　 to paint the lily 画蛇添足
　　 to help a lame dog over a stile 雪中送炭
　　 as easy as falling off a log 易如反掌
　　
　　有些成语由于不同文化背景的缘故，无法通过字面的意思来理解其中的比喻意思，例如：
　　 in a pig’s whisper 低声地；顷刻间
　　 hang on somebody’s sleeve 依赖某人
　　 to be full of beans 精神旺盛
　　 to get cold feet 感到怀疑、害怕或胆怯
　　 a skeleton at the feast 扫兴的人或东西
　　粗枝大叶 to be crude and careless
　　扬眉吐气 to feel proud and elated
　　无孔不入 to take advantage of every weakness
　　大张旗鼓 on a large and spectacular scale
　　风雨飘摇 (of a situation)being unstable
