Exercise 5 – Paragraph Writing 

I cannot go to the park today because it isn’t sunny. It looks like it’s going to rain soon. My friends haven’t called me yet to make any plans, so I won’t be meeting them. I didn’t bring my jacket, and it’s too cold outside to stay comfortable. We aren’t allowed to play outside when it’s raining, so I guess I’ll just stay inside and read a book. I don’t mind, though, because I like reading stories and learning new things. Even tomorrow, if it’s cold and rainy, I will not be able to go to the park and play with my friends.
