2. I am doing something = I'm in the middle of doing something; I've started doing it and I haven't finished yet. Often the action is happening at the time of speaking: * Please don't make so much noise. I'm working. (not 'I work') * 'Where's Margaret?' 'She's having a bath.' (not 'she has a bath') * Let's go out now. It isn't raining any more. (not 'it doesn't rain') * (at a party) Hello, Jane. Are you enjoying the party? (not 'do you enjoy') * I'm tired. I'm going to bed now. Goodnight!
