be worth to do sth是错误的,worth后面只能接ing形式。be worth doing sth:值得做某事比如说: 这本书值得一读
This book is worth reading.
=This book is worthy of being read.worth 没有be worth to do 的用法
be worth doing 主动表被动,“值得做……”sb./sth. be worth... “值……” worth常用于sth is worth v -ing结构中,动名词短语在这里表示被动意义。本结构中的sth 有时可换用it,这时it是形式主语,动名词短语是真正主语。
