To my surprise,the young girl laughs in the way -----her mother did at that age .

问题描述:

To my surprise,the young girl laughs in the way -----her mother did at that age .
横线部分为什么不填in which 呢,然后看为way做her mother did at that age的先行词?

way做定语从句的先行词时,后面定语从句的主语通常也是前面句子的主语,如:I like the way in which you talk to me.但这里不是.这是方式状语从句,删去in the way 也是通的.
