Sample writing
No More Mystery in the Neighborhood
Last week, in a quiet neighborhood, something strange happened. Residents heard noises in the night but no one knew why. Victor Smith thought that 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 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 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.

Sample
I found a pink schoolbag when I was cleaning the classroom. It can’t be a boy’s because none of them likes the color. Who can the schollbag belong to
There are only two girls who said they lost their schoolbags. They are Lily and Tina. And a purple hair band is in the schollbag, so it might belong to Lily.
But it is hard to know the answer because both Lily and Tian use the hair band.
Then I found a comic book in the bag. Now there is no doubt that the wallet belongs to Tina. She is the person who like reading comic books best in our class.
