When I was 19，I got a job in my local bookstore.     (live) in the large city，I usually saw many strange customers，most of     were teenagers. They didn't come often；I forgot all the customers     two. One night a 15-year-old girl came in looking for a book with a boy. They seemed to find    they wanted to buy. But when they came to the counter, the girl found she was a dollar or two short to buy the book，and she took       all her money to prove it. She looked so     (disappoint). Just then I remembered my discount card and it was still active，so I told the girl not     (worry). I put in my code，being happy that I could help them with this card. With the book       her hand she gave me a thankful smile，and then she and the boy got out of the store happily，leaving me    (feel) content，too. This experience     (influence) me deeply every day since then. In fact, sometimes a little thing can also make one's world beautiful.
