101. Her household bills piled up, along with the dishes and dirty laundry, but it took near-constant complaints from her four daughters before she realized she had a problem.

译文

她有一堆没交的家庭账单，没洗的餐具和脏衣服也堆积如山，然而在她的四个女儿不停地抱怨之后，她才意识到自己有问题。

点睛

本句是由but连接的表转折关系的并列句。第一个分句的主干为bills piled up，短语along with引导伴随状语；第二个分句的主干是it took complaints, from her four daughters为后置定语，before引导的是时间状语从句，其中还包含realized 的宾语从句she had a problem。
pile up的意思是“堆积，积压”。如：
Complaints piled up against the service. 有关服务的投诉不断堆积。

考点归纳

before作为连词引导时间状语从句时，通常包含以下几种意思：
意为“在……以前”。如：
Would you like to leave a message before you go? 你在走之前想留个口信吗？
意为“直到……为止，到……之前”。如：
It may be some time before we really understand the problem. 或许要过一段时间我们才能真正了解这一问题。
意为“以免，不然”。如：
Put the scissors away before you get hurt. 把剪刀收好，免得你被伤到。
