I am not good at grammar, do you have any good ideas? answer: there are not many ways you can do, really. you will have to try to do more exercise and try to remember them. practice makes perfect

Best thing to do, is to chat in english. Copy sentences from textbooks. After a little while, those sentences will become very familiar. You will not need to copy them, then you can add more sentences.

There are some websits can help you, just read them and remember them try your best. http://www.bbc.co.uk/worldservice/learningenglish/radio/specials/1535_questionanswer/page42.shtml I have got improved my grammar in there.
