问题描述：
3020102（zhang）:within less than twenty years,the peregrine became extirpated from much of its range,and was barely clinging to existence in most of the remainder.
想知道的问题：
1—much of its range 改变成 its much of range
答
1、much 属于不定代词,指代不可数名词的数量.一般说来,不定代词前不用冠词、物主代词、名词所有格、数词一类的限定词修饰.如：
not much of a scholar（不是什么了不起的学者）不能说成 not a much of scholar.
most of the remainder （残存者中的多数/多数残存者）不能说成 the most of remainder
同理 much of its range 也不能说成 its much of range.
2、难点
range 由涵盖的范围引申为动植物地理分布区
much 指代大量分布区
cling to 依附,坚持,固守
参考译文：在不到20年内,这种候鸟从大量的该分布区中灭绝,在多数残存者中它们几乎不能坚持着生存下去.
