I wouldn't like to ........................................... get up at five o'clock every morning. We ........................................... do any washing-up after the picnic because we'd used disposable plates and cutlery. Do professional musicians ........................................... practise every day? I ........................................... have bothered cooking all that food; they’d eaten before they arrived.
