Early autumn is a beautiful and pleasant season
Thursday and Friday are week days
My brother is fifteen years old
In winter nights are long and dark
October and November are autumn months
I know a lot of children in my school
You can see a lot of beautiful flowerbeds near my school
We can sing the song about four seasons
