Before Monica goes to bed, she looks out of her window and sees the Moon. The Moon looks so beautiful. "I wish I could get the Moon," thinks Monica. But no matter (无论) how hard she tries, she cannot get the Moon. "Papa," Monica says to her father, "please get the Moon for me."
Papa gets a very long ladder (梯子). He carries the very long ladder to a very high mountain. Then Papa puts the very long ladder on top (顶部) of it. Up and up he climbs. At last, Papa gets to the Moon.
"My daughter Monica would like to play with you, but you are much too big," says Papa.
"Every night I get a little smaller," says the Moon. "When I am just the right size, you can take me with you." After a few days, Papa takes it. Down and down he climbs.
"Here," Papa says to Monica, "I have the Moon for you." Monica jumps and dances with the Moon. But the Moon keeps getting smaller and smaller. And at last, it disappears. Then, one night, Monica sees a small Moon come out. Each night the Moon grows, grows and grows.
