Read the messages posted on the internet forum related to smoking. Circle the correct verb forms.
a) I tried /have been trying to quit smoking for a long time now, but have failed / have been failing a number of times. I don't know /didn't know what to do. It's a battle. Can anybody help?
b) I have passed/ passed the two month anniversary without smoking. Just wanted to tell you that I do / am doing GREAT. It makes me feel good to say, I am not smoking/ don't smoke. Thank you very much for all your advice. It has worked / had worked!
c) I am / have been smoke-free for over a month. It can be done! Smoking over a pack a day for 10+ years? just think about the harm you were doing / have been doing to people around you for all this time. Think and do something now! And say hello to the rest of your life. I have / had and it feels great
