One possible version

       I think we should learn to do housework, although we are very busy working at our lessons. I often

wash dishes after dinner at home, for Mum has to cook supper every day and she must be very tired after

a day's work. As a child, I should do my bit for the family.

       I'm going to learn to cook and wash clothes in this summer holiday. And I'm sure my parents will be

happy.
