In order to improve my essay writing,I decided to write one essay each day,and mail it to my teacher in order to correct it.I don't really know what topics to write about,and so I would be very pleased if you suggest some interesting topics.Thanks
Write about things you are interested in. If I give you a topic, it might be something you are totally disinterested in and you will be bored writing it. If you're bored, you won't write well.
I'm sure you can think of plenty of subjects you are already interested in.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
