稍一熟悉美国人之后,你会发现他们仍旧直率可爱象个大小孩.美国人自命为富有幽默感的民族,如果你骂他不学无术没出息,他反而认为你被物质和名誉所累,不懂得生活的真缔而可怜你；可是如果你骂他呆头呆脑没有幽默感,他一定会感到莫大的羞辱.美国人老老少少,男男女女,无时无地,彼此交谈搭讪,都以寻开心为目的,让语言环境轻轻松松为准则.有时你看见一群人嘻嘻哈哈热闹非凡还以为是老朋友在聚会,其实他们彼此认识的时间大概还没有十分钟.
Once you are slightly familiar with the Americans,you would find them still frank and lovable like a big kid.The Americans regard themselves as humorous people; if you criticize him for not enterprising and hopeless,he may counter that you are caught up with materialism and fame,ignorant of the true meaning of life and pity you; but if you brand him as an idiot with no sense of humor,he would definitely take it as a great humiliation.
The Americans,whether old or young,men or women,whenever or wherever they are chatting or striking up a conversation,the goal is to have fun and so the norm is to have dialogues in a light and easy ambience.Sometimes,you see a group of people bustling and tittering with joy,you may think that they are old friends having a gathering; as a matter of fact,they can be acquaintances of less than ten minutes.
美国民族很重要的一点是很讲信誉（当然,不是所有的美国人都是有信誉的人）,因为美国的经济和社会地位是建立在个人的信誉基础上的.如果你在这方面和他开玩笑说他骗人,不老实,他会马上翻脸--美国人说翻脸就翻脸,没有情面可言.
One important point of the American nationals is their credibility (of course I am not saying all of them are men of honor); this is due to the fact that the U.S.economy and social status are established on the basis of personal integrity.If you joke about this and accuse him of being a cheat or dishonest,he may immediately turn hostile – Americans can fall out with you in no time,without sparing your feelings.
