dear Billy, i know you have some problems in learning english, don't worry, i used to have this problem in the past but now i dont worry about it. I hope you spend more time on reading english loudly, because when you read and listen to yourself, you could remember things. Of course, listen to english songs and learn from that is also good, if you have time, please watch some english movies, they have very simple english there! good luck, my friend!
