根据短文内容,从短文后的选项中,选出能填入空白处的最佳选项.选项中有两项为多余选项.

     My mother is a diligent and kind woman. She is very busy from morning till night. As a

teacher, she works hard.    1    Both my brother and I love her dearly as she loves us.

My mother has been teaching math at a middle school in my hometown. She goes to work

early in the morning and does not return home until late in the afternoon.    2    She treats

them with patience and teaches them well. For her excellent quality and very good teaching

results, she has been elected as a model teacher several times.

     3  .  Every day, when she comes back home from work, she sets about doing housework,

sweeping the living room and bedrooms or cleaning the furniture, and putting everything in

good order. She seems to be busy all the time. As she has been very busy working every day,

she looks older than her age. But she looks as cheerful and happy as ever. Mother never buys

expensive dresses for herself, but she often buys some inexpensive but high quality clothes for

us.    4    She just eats a plain meal outside when she is too busy to cook herself. She lives a

busy yet simple life, without any complaints.

     Often she says to us, "work while you work, and play while you play. That is the way to be

happy and gay. If you do not work, you will become lazy and be of no use to society". What a

piece of good advice this is!    5  .  This advice of hers will always serve as a guide to my behavior.
