The moment I picked up the receiver, I __________ the voice of Helen Bates.
-I think I'll give Bob a ring.-You __________. You haven't been in touch with him for ages.
-What do you think we can do for our aged parents?-You __________ do anything except to be with them and be yourself.
I can't leave. She told me that I __________ stay here until she comes back.
I __________ use a clock to wake me up because at six o'clock each morning the train comes by my house.
-__________ you interrupt now? Can't you see I'm on the phone?-Sorry Sir, but it's urgent.
