阅读短文,按要求完成各题。

    I was ten when I first sat with my grandmother behind the cashier(收银台)in her general store.____ I quickly learned the importance of treating customers politely and saying “thank you.”

    At first I was paid in candy.____ I worked every day after school, and during the summer and on weekends and holidays from 8 a.m. to 7 p.m. My father helped me set up a bank account.____ 

    By the time I was 12, my grandmother thought I had done such a good job that she promoted me to selling cosmetics(化妆品). I developed the ability to look customers directly in the eye. Even though I was just a kid, women would ask me such things as “ What color do you think I should wear?” I took a real interest in their questions and was able to translate what they wanted into makeup(化妆)ideas.____

    The job taught me a valuable lesson: to be a successful salesperson, you didn't need to be a Rocket scientist—you needed to be a great listener.____ Except they are no longer women purchasing cosmetics from me; instead, they are kids who tell me which toys they would like to see designed and developed.

A. Later I received 50 cents an hour.

B. Before long, she let me sit there by myself.

C. I ended up selling a record amount of cosmetics.

D. Today I still carry that lesson with me: I listen to customers.

E. My grandma's trust taught me how to handle responsibility.

F. Soon I found myself looking more beautiful than ever before.

G. Watching my money grow was more rewarding than anything I could have bought.
