1. Speechless
因为厌恶或者吃惊而无语~
例：I'm so tired of my friend's excuses that I am speechless。
我朋友总是找各种理由来搪塞我，简直无语了我！

2. 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。

3. Have nothing to say for oneself
不打算说，也不想说，总之不准备向别人透露自己的想法~
例：She doesn't have much to say for herself。
她自己无话可说。

4. Keep (yourself) to yourself
真正的“独孤求败”来啦！沉默寡言，对别人的事情从来不感兴趣。
例：Nobody knows much about him; he keeps himself very much to himself。
谁都不了解他，他这人很少与人来往。

5. Not be on speaking terms (with somebody)
这个短语的意思是因为还在生某人的气，不愿意跟他讲话。
例：She's not been on speaking terms with her uncle for years。
她已经好几年没再跟她叔叔说过话了。

6. Lost for words
有种没话说是因为不知所措。当你感到非常惊讶或困惑时，有时真的不知道该说什么好。
例：I was so surprised to see her that I was lost for words。
见到她太意外了，我一下子不知道该说些什么了。
