阅读理解Thousands of miles from the Earth, in outer space, is a small planet, Fliptune. It is dark and cold, far from the Sun, behind a much bigger planet. Little green aliens (外星人) live there. They use torches (手电筒) to see.
One day, a young alien, Neila, put the wrong batteries (电池) in her torch.
Suddenly (突然), there was bright light. It went up into the sky, around the Sun and reached the Earth.
The light hit a boy called Billy and his dog. Neila quickly turned the torch off, but the pair were caught by the light. They flew through space and landed near Neila.
"Hello, " said Billy. Neila smiled.
"Wow!" said Billy, "Everything's made of ice cream!"
"The ice cream never melts, and nobody eats it. It's too cold here, " said Neila.
Neila looked sad. "Can you help us?" she said, "We need sunshine to make things grow. "
"No problem, " said Billy, "Can you get us home? I have an idea. "
"Wait there!" said Neila. She got her torch, put the wrong batteries in again——ZOOM! Billy and his dog flew back to the Earth.
Billy pointed his bedroom mirror (镜子) between the Sun and Fliptune. The sunlight bounced off(弹出) the mirror and up onto Neila's planet.
Thanks to Billy, Fliptune is not cold any more. Billy moves the mirror every day to keep the sun shining there. Now Neila and her friends sit in the sun and enjoy all the free ice cream.
