Sample writing
No More Mystery in the Neighborhood
Last week, in a quiet neighborhood, something strange happened. Residents heard noises at night but no one knew why. Victor Smith thought it was teenagers having fun while Mrs. Smith and their neighbor, Helen Jones, blamed it on animals.
We now know what was happening in the neighborhood. A ranger’s station（护林站）was being built in the nearby forest. Trees had to be cut down to make space for the station. This affected some animals living in the forest. A raccoon（浣熊） family lost their home and had problems finding food. The raccoons discovered food in the neighborhood’s garbage bins, so they came back every night.
Now the mystery is solved. People in the neighborhood feel sorry for the raccoons and they are trying to help them.
