A unicorn(独角兽) is a kind of animal. They look like horses, but one thing is1 . Unicorns have a pointy horn(角) in the middle of their head. People have written about unicorns in many stories. Still, no one has seen a2 one. But a girl named Betty really believes in them. She wants one to be her 3 .
Betty is a first-grader and 4 in a city. Recently, she sent a letter to AnimalControl that gives pet licenses(许可证). She asked 5 in the letter,"Dear Jessy,I wonder if I can have a unicorn as my pet in my backyard."
Jessy, head of Animal Control, felt surprised because nobody else had ever6 a unicorn license. But she liked the girl's interesting 7 . So she wrote,"To keep a unicorn, you have to 8 three rules. First, clean its horn every month. Second,it must be 9 watermelon once a week. Third, take it to see sunlight, moonlight and rainbows."
Betty's mother has a 10 for what comes next. She will take Betty to Animal Control on her birthday. There, the family will receive a printed unicorn license together with a toy unicorn as Betty's pet until she finds a real one.
