Around six weeks ago, Kaileen came running into the house, just getting off the bus from school. She was all excited about a story about homeless pets because of Hurricane (飓风) Katrina and all that was going on to help them. She said that this information came from her animal newspaper (your KIND News). Kaileen has a great love and compassion (同情心) for animals, so her excitement did not surprise me. Her next ideas, however, did. She said that we should go around right then to our neighbors and collect all their change to send to the animal shelters (保护所).

I thought this was a school project, but in fact, it was not. This was what Kaileen wanted to do on her own! Well, it warmed me all over. To see your child so willing to help others just lets you feel that maybe you had done something right in raising (养育) her.

Anyway, I told her to make a card and send it out to our neighbors first. With the help of her older brother, Kaileen soon made a lovely card that asked our neighbors to help these pets by giving their spare change. She gave them a few days and a date she would come by to pick up any donations (捐赠). 

Well, I had to go out and buy a donation box. Kaileen collected $279.50!!! I just thought you would like to know how KIND News had touched a little one’s heart and given her the idea to show her compassion for animals. Thank you — we really enjoy your paper.

36. The passage is probably taken from ______. 

A. a report about a warm-hearted girl

B. an advertisement for an animal shelter 

C. a thank-you letter to a newspaper

D. a donation program for homeless pets 

37. What was the author’s feeling about Kaileen’s idea? 

A. Pleased and excited. 

B. Surprised and moved.

C. Tired and sad.                         

D. Worried and angry.

38. From the passage we learn that KIND News ______.

A. collects donations for homeless people 

B. sets up many shelters for homeless animals 

C. tells children how to keep pets healthy 

D. encourages children to help homeless pets 

39. We can infer that the passage is written by Kaileen’s ______.
