1. There were six children crowded into the tiny space.
点拨:crowded into the tiny space是过去分词短语做后置定语。文中提到是6个小孩,这6个小孩是一个挤一个,那么个个都是被挤,crowd就和children是被动关系,所以用过去分词短语。
2. Looking after so many children had aged Joan Durbeyfield,but she still showed some of her early prettiness,which Tess had inherited.
点拨:looking after so many children had aged Joan Durbeyfield动名词短语做主语,which Tess had Inherited是一个非限定性定语从句,修饰前面的先行词prettiness,补充说明苔丝母亲的美貌所带来的影响,起着的作用。
