expressing

express, air, broach, utter, vent, voice

这组词都有“表达”的意思。它们的区别是：
express含义最广,可指口头、笔头或用其他任何方式表达思想、感情、经历、构思或个性; air指宣扬某人的看法,希望引起公众的注意或获得同情; broach强调首次提出,尤指经过深思熟虑之后或等待辩论; vent强调无法控制地发泄或吐露强烈感情; voice专指用言语强有力地表达出一个人的思想、意见或感情; utter指突然发出某种强烈的声音。例如:
I can't express it properly.我不能恰当地把它表达出来。
He is ready to air his views to anyone.他乐于向人发表他的观点。
At last he broached the subject of the new contract to them.最后他向他们提出新合同的问题。
The wounded man uttered a groan.那受伤的人发出痛苦的呻吟。
He had had a bad day at work and vented his anger on his family.他整天不顺心,便拿家里人出气。
The chairman encouraged us all to voice our opinions.主席鼓励我们发表自己的意见。

下面三个句子的意思相同:

我无法用语言表达我的悲伤和懊悔。
