5.bite my tougue: 忍住不说，not gonna talk about something.
You better bite your tongue and not say a word of this to anyone! 你最好保持缄默,而且对任何人一个字也不要说!
Bite back (something)/ bite (something) back
想说又不能说，话到了嘴边只能咽回去。英文里bite有“咬”的意思，bite back“咬回去”，这个短语形容“欲言又止”是否很生动呢？
例：I attempted to smile sweetly while biting back angry comments.
我尽量挤出一丝讨喜的微笑，把一肚子气话都咽了下去。
