Hi ! Nina,

Hello there!

Thank you for sending a composition.

It\'s actually sunny here in our city. ^^,

Anyway, I made some corrections to your sentences but I\'m not quite sure if I got your ideas correctly. ^^,

Yes, there are some rules that you have to follow for you to make better sentences.

For a start, you have to be more familiar with the basic sentence patterns. ^^,

I hope that you won\'t be too worried about committing mistakes. Take it positively and learn from it.

Anyway, if you have any questions, please ask me during our class.

See you!

~T. Nina~
