When I was in college, a white cat liked to show up on our campus from time to time. It was1that he was a homeless cat because he looked thin and weak. Students would 2 him after class and feed him all kinds of food. The school didn't say3about the cat for a long time.

But one day, we were 4 that one of our fellow students had an infectious(传染性的)disease and it was said that the cat was 5 the source(来源). After that, we were not 6 to touch any homeless animals on campus. The school started to take turns to keep animals 7 campus, too.

Since we couldn't feed the white cat, it was8 for him to find food on the street. He9weak and skinny. But 10the rest of us ignored(忽视) the cat, a security guard at our school decided to take on the responsibility of caring for him. He took the cat to a veterinarian (兽医) for a health check. He then went to a nearby11 and bought food for the cat, 12 a small bed for him to sleep in. He made sure the cat was13 and comfortable.

It might seem like a (n)14effort to some people. But this man asked his job-his only source of income-15 to feed a tiny cat who no one else cared for. It was a very heart-warming thing to see. If each of us can do something to help with things or people around us we can make our world a better place.
