Помогите, пожалуйста...
Нужно употребить либо в Present Perfect, либо в Present Perfect Continuous
15. Your eyes are red. You (cry)? 16. Where on earth you (be)? I (wait) for so long! 17. Bill, you have got a black eye again. You (fight)? 18. Do you think George (finish) the translation? He (write) for so long! 19. I think I can smell smoke on Debbie's clothes. I'm sure she (smoke). 20. Here you are! I (look for) you everywhere. Where you (be)?

Present Perfect Continuous никогда не употребляется со вспомогательным глаголом to be во второй форме. Только have/has been.

Напишите пожалуйста правильно

15.Crying;16. Was/Waiting; 17. Fighting; 18.Finished/Writing; 19. Smoking; 20. Looking for/Was.
