1、首先这个短语从字面上理解就是“敲打灌木丛”你可以想象你在敲打灌木丛找东西，很难发现目标，只是在瞎碰。
一，To speak vaguely or euphemistically so as to avoid talking directly about an unpleasant or sensitive topic.模糊，委婉的说着话，为了避开谈到不愉快或敏感的话题。请看图
2、二，逃避，拖延 浪费时间而不愿意回答问题，to avoid answering a question; to stall; to waste time.
3、三，要学以自用，比如你今天学到了这个短语，自己试着举几个例子，把它用起来，用到对话中去，就会事半功倍。
4、要多看一些英剧，美剧。很多剧里面都有这个短语的。学习Native speaker把这个短语用在什么场景下的。
5、最后我给大家给一个对话，希望能帮助大家跟好的理解，吸收。

wife:i love you ,do you love me?
