经济学人原文：

LISTEN carefully to the footsteps in the family home, especially if it has wooden floorsunmuffled by carpets, and you can probably work out who it is that is walking about.

2. , especially if it has wooden floors 尤其，进一步说明在一种情况下

3. unmuffled by carpets在过去分词作floors 的后置定语, 

4. who it is that is walking about是作work out 宾语从句

5. who it is that is walking about是强调句，正常语序是it is who that is is walking about

翻译：仔细听家里的脚步声，特别是家里铺的是木地板而又没有地毯消声的话，你大概可以辨认出是谁在走动。——经济学人官方译文
