微笑，永远是微笑者个人的专利，它既不能租，又不能买；既不能借，又不能偷。
本句根据句意可以分为两部分。第一部分是“微笑，永远是微笑者个人的专利”，是对微笑的内涵介绍。第二部分是“它既不能租，又不能买；既不能借，又不能偷”，是对前面的解释说明。在第二部分的句子中，汉语使用的是主动句，但实际含义是被动的意思，即“微笑不能被租，不能被买；不能被借，不能被偷”，它自己是无法行动的，所以在翻译时要使用被动的形式。
Smile is the patent of its owner. It can not be hired or bought, nor can be borrowed and stolen.
汉语有很多“主动表被动”的句子，如“鲸鱼杀死之后，就在岸上扒皮了。”译为“When the whale is killed, it can be striped out on the shore.”只有在正确理解原文意思的基础上才能识别被动含义，进而进行正确的翻译。
这种笑脸又能产生多种功能：它能使某些人之间的生疏成为亲密，使某些人之间的隔阂变成融洽，它能使失意成为顺意，使烦恼成为愉快；它能使人们的心灵沟通，感情交融……
本句可以分为三部分，第一部分是总起句“这种笑脸又能产生多种功能”，第二部分位于分号之前，“它能使某些人之间的生疏变成亲密……使烦恼成为愉快”，第三部分则是“它能使人们的心灵沟通，感情交融”。在第二部分的原文中都包含“使……变成……”的结构句，在翻译时不能按原文结构来翻译，这个结构的意思就是“消除……替换为……”，依照这个意思去翻译，更符合用语规范。
It can boast of many functions: including making people become intimate, removing the estrangement to foster harmonious relationship, replacing the disappointment with satisfaction and changing distress into happiness. It can bridge the souls and mingle the feelings.
对于汉语中多次重复的词语，在翻译时往往不能照搬原词来翻译，我们要在理解原文真实意思的基础上进行翻译。
