LIKE nha bạn!

My favourite subject is called English because I really like writing and when I read any books, they are such interesting books ,well not the ones that are about weapons the ones that have a mystery in it and when there is a mystery in it I try to solve the problem. when I finished solving the problem I read the next page and then when the problem is solved iI get it right!!!!!!!!! but sometimes I don't. I really like to have spelling tests so then what ever spelling I get wrong I can learn them and speak those spellings, it also helps me write my sentences right and make sure that they make sense. I first didin't get what english was or what it does, so when I was in 3,4,5 and in year 6 I started to know what English was so then I started to like English and then I tried to work hard in it. 

I hope your favourite subject is English too!
