“快马加鞭”，汉语成语，意思是跑得很快的马再加上一鞭子，使马跑得更快（whip the flying horse to an even swifter speed）。比喻快上加快，加速前进。可以翻译为“accelerate the speed，go faster”。
例句：
要赶超世界先进水平，我们还得快马加鞭。In order to catch up with and surpass the advanced world levels, we'll have to accelerate our speed.
这项工作必须快马加鞭地进行。This work must be carried out at top speed.
