Making a note

I'd like to record my mistake on speaking for an English call class. Sometimes but actually often, I feel hard to find the correct expression or fit words with my thought. Yesterday, I wanted to say that someone throws a trash on the street, instead of someone makes a trash. I don't know why my english words memory is getting worse than before. The words that I already know have lost in my mind when I say something. What should I do to improve my memory? I'm trying to read English books at least for 30 minute and three times a week. Do you have any idea to help me? then please share it.

It's good hear that you're aware of your weakness and you acknoweldge it. I think the reason why you sometimes forget the words that you already know is because you don't have that much opportunity to talk in English. Just try to review those words in your mind and try to make use of those words as often as possible. You are doing the right thing in class and I'm always thankful that you're expressive. Continue your good habit of reading English books. We just need to practice more. See you again!
