And
every where and always, is the dear old wrinkled face of her whose firm,
elastic step mocks the feeble saunter of her children's children, the
old-fashioned grandmother of twenty years ago；摘自《美国语文》中学课文第4课 Our
Old GrandMother
老师好，
1. 这个句子倒装原因是（1）头重脚轻（2）和上一段文字承上启下，此外，还有其他原因吗？
2.
句末the
old-fashioned grandmother of twenty years ago 作何成分？是her
的同位语吗？谢谢老师。
