You probably want to watch TV and movies more often. Turn the caption on,
follow the characters to read those dialogs. If you keep doing this,
although at the very beginning you may not be able to follow them, those
sentences could become yours eventually when you talk to people. And pay
more attention to the sentences used by people or in books. Remember them
and try to use them in your daily life. This is what I did when I first came
here. I rented DVDs, watched TV shows. I could not say I am the one who can
speak English as a native speaker. This is a life-long goal to achieve. But
I am confident and feel comfortable to speak English.
