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. 【小题4】
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. 【小题5】Expect 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.

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. B
答案：
(答案→)B
解析：
【小题1】选B。从后一句I quickly learned the importance of treating customers politely and saying“thank you”. 可推知, 作者的祖母先让作者跟着她学, 然后让作者独立工作, 所以他很快懂得有礼貌地对待客人的重要性。
【小题2】选A。前面有at first, 和本项中的later一致。
【小题3】选G。根据前一句的My father helped me set up a bank account. 可确定答案。
【小题4】选C。同样根据前一句确定答案。
【小题5】选D。上文提到a valuable lesson, 这里承接上下文。
