1. Is it anything to do with father making such a fool of himself this afternoon？’asked Tess，frowning．

点拨：frowning在这里是现在分词做伴随状况状语，而making such a fool of himself是现在分词短语做后置定语，修饰father。被修饰词father和分词中的动词make是主动关系，所以用现在分词。

2. They've discovered we're the oldest family in the whole country，going back a long way！

点拨：going back a long way是现在分词短语做后置定语修饰名词family。
