一屋不扫，何以扫天下。老吾老，以及人之老：幼吾幼，以及人之幼。两句的英文怎么说？

How can you clean this world if you cannot clean your own room? Take care of your parents and other elderly people. Take care of your children and other people's children.

Sweep your house before conquering the world.
Expend the respect of the aged in one’s family to that of other families; expend the love of the young ones in one’s family to that of other families.

不要试图用英语翻译这种古文。一般都是不标准的！我们中华民族的汉语言文学是没有哪个国家的语言可以比拟的！所以这么精深的古文，没法翻译。
