10.My Best Enemy
Once again,I was in a new school.So was a girl in my class named Lisa.That's where the similarities ended.
I was tall and she was small.My thick black hair had been recently cut short into an untidy style.Her natural blonde hair flowed to her waist and looked great.!was 12and one of the oldest in the class while she was 11and the youngest.I was awkward and shy,she wasn't.I couldn't stand her,considering her my enemy.But she liked me and wanted to be friends.
One day,she invited me over and I said yes--I was too shocked to answer any other way.My family had moved six limes in six years,and I had never managed to develop any friendships.But this girl who wore the latest fashions wanted me to go home with her after school
She lived in a fun part of town that had two pizza places,an all-right bookstore,a movie theater and a park.As we walked from the school bus stop through her neighborhood,I tried to guess which house might be hers.Was it the white one with the perfect lawn or the three-story house with a front porch?I got very surprised when she led me into an old apartment building.She lived on the fourth floor in a two--room place with her mother,her stepfather,her two brothers and her sister.
When we got into the room she shared with her sister,she took out a big case of Barbies.whichwas my next surprise.I had never played with them.We sat on the floor,laughing as we made up crazy stories about the Barbies.We found out that we both wanted to be writers when we were older and both had wild imaginations.We had a great day that afternoon.
Lisa was loved by the whole neighborhood.The bookstore owners lent her fashion magazines the movie theater gave her free tickets…..Soon I was included in her magic world.We slept over at each other's houses and spent every free moment together.
Lisa,my first real friend since childhood,helped me get through the rough years of early adolescence(青春期)and taught me an amazing and very surprising thing about making friends:you worst enemy can turn out to be your best friend.

7.Tom was called off to dress for Sunday-school.
Mary gave him a tin basin of water and a piece of soap,and he went outside the door and set the basin on a little bench there; then he dipped the soap in the water and laid it down; turned up his sleeves; poured out the water on the ground,gently,and then entered the kitchen and began to wipe his face diligently on the towel behind the door.But Mary removed the towel and said:
"Now aren't you ashamed,Tom.You mustn't be so bad.Water won't hurt you."
Tom was a little unsettled.The basin was refilled,and this time he stood over it,took in a big breath and began.When he entered the kitchen presently,with both eyes shut and feeling for the towel with his hands,an honorable testimony of bubbles and water was dripping from his face.But when he came out from the towel,he was not yet satisfactory,for the clean territory stopped short at his chin and his jaws,like a mask; below and beyond this line there was a dark expanse of unirrigated soil that spread downward in front and backward around his neck.Mary took him in hand,and his flooded hair was neatly brushed,and its short curls formed into an elegant and regular general effect.Then Mary got out a suit of his clothing that had been used only on Sundays during two years--they were simply called his"other clothes"--and so by that we know the size of his wardrobe.After he had dressed himself,Mary checked over and over again.Now he looked extraordinarily improved but uncomfortable.He was fully as uncomfortable as he looked; for there was a self-control about whole clothes and cleanliness that annoyed him.When Mary brought out the shoes,he lost his temper and said he was always being made to do everything he didn't want to do.But Mary said,persuasively:
"Please,Tom-that's a good boy."
     So he got into the shoes howling.Mary was soon ready,and the two children set out for Sunday-school--a place that Tom hated with his whole heart; but Mary was fond of it.
