原文:... six helpless creatures who had not asked to be born at all,much less to be part of the irresponsible Durbeyfield family.
第一、定语从句:
who had not asked to be born at all是个定语从句,修饰前面的先行词creatures,它指人,在定语从句中做主语,那么可以用的引导词可以是“who”,也可以是“that”。这里是用who。
第二、省略句:
much less to be part of the irresponsible Durbeyfield family是在定语从句中的省略句,完整的句子为who had much less not to be asked to be part of the irresponsible Durbeyfield family。
