How happy I am to celebrate my (fifteen) birthday tomorrow!
My grandma is interested in taking (photo) with her mobile phone.
Mum,have you finished (cook)?Is there anything I can do for you?
The seat is hard and (comfortable) to sit on,so I have a sore back.
The math problem isn't difficult,and I can work it out (easy).
The (five) talent show gave us a big surprise.
