She has short hair that is gradually   2 white,an indication that age is creeping on her.The wrinkles (皱纹) that line her face   3  of years of hard work and selfless devotion to her students.She wears a pair of glasses through which her kind eyes are always   4  fixed upon us with affection and consideration.She looks

splendid in her   5  clothes which she will not throw away for something more  6  ,reflecting a thrifty (节俭的) nature.Through her,we have learned to be more careful with   7  .Not only that,she has also taught us the  8  of filial duty (孝道) by setting us a good   9  of looking after her eighty-five years old mother.
