some intresting sentence: 去死吧！(Drop dead!) 走吧！（go!） 是死了吧？（is him/her dead?） 你瘋了吧！（you crazy!）

When you say something you not sure,you can use it. Eg: I won’t tell you what time to leave; you’re old enough to use your own discretion. 我不会告诉你该什么时候走的,你这么大了自己拿主意吧。 Come to think of it, it could also be the way to get us out of this mess. 考虑一下吧,我们可能还可以借此摆脱混乱. I wonder if you could excuse me for a little moment. 你不介意我先失陪一下吧。 You don't want to pay money to see a movie version of a TV show, do you? 你不会想花钱去看一些看起來像是电视节目档次的电影吧? Are you clear?

what question did a chinese ask you?

But why did a Chinese ask such a question?

The answer of mine when I answered the same question on Italki. According to this page >>> http://dict.baidu.com/s?wd=%B0%C9&f=3 and (which is in the '详细解释' box) >>> http://www.zdic.net/zd/zi/ZdicE5Zdic90ZdicA7.htm Except the usage as an 'onomatopoeic' word (word to imitate some sound) and the transliteration of the English word 'bar', roughly explaining as follow (when used as an auxiliary word) 1. (used at the end of a sentence) indicating entreaty, suggestion, command, etc 2. indicating agreement or acknowledgment 3. indicating doubt 4. indicating uncertainty 5. indicating a pause
