听力原文: I come from a big family.. three brothers land a sister.., and we all work in the family business. We make cakes. We used to have a small shop that sold bread and other things that we made, but now we just make cakes and bread and deliver them to shops here. My father started the business, but he died six years ago and as I said, my mother is taking care of it now. Even before he died, when she was looking after the children and running the house, she helped him a lot with the business. So when Dad fell ill, it wasn't difficult for her to take over from him. My older brother, George, was already helping a lot then, and I used to help out at weekends too, even when I was a child
