一、完整文章（答案已填入）
PASSAGE · 浅黄色 = 填入的正确答案P1 I was on my way home and remembered I needed to buy a special type of cat food from the vet (兽医). It all started with my daughter's love for homeless1 cats. She found a little one on the street and the cat needed special food2 because of her poor health. It was too expensive for my daughter to afford3, so I decided to go to the vet to buy some. But I didn't know how long the cat's condition would last4.
P2 I asked for the food and the assistant (店员) quickly handed it to me. At that time, another customer5 came to pay. I wasn't in a hurry, so I said, "Go ahead and you can pay first."
P3 The gentleman smiled and said, "You should go first. You were here before me." I smiled6 back and insisted (坚持). He replied, "Wow, how can I thank you?"
P4 Without thinking, I jokingly7 said, "Maybe you can buy me a case of cat food." I didn't think about8 it anymore. But when I came back ten minutes later, the vet assistant had a big smile on her face.
P5 "You don't have to pay anything!" she said. "The man bought the food for you!" I was surprised9. "What? Are you serious?"
P6 "Yes! He said that sometimes people helped him and now it's his turn to pass it on." I've always enjoyed helping people or animals, but I never expected to receive a kindness in return. It reminded10 me that small acts of kindness can make a big difference.
