英语作文一篇i want to do something for my family

My family is not a very big one, there are three mumbers: my Dad, Mum and I. I am the only member that don't make bread. But I really want to do something for my family.
First, I think I can do some chores. Both Dad and Mum are busy all the time. They leave home early and come back late. I am learning to cook simple meals for us. Washing clothed is not a difficult thing for me. Second, I think I can do something to care abou them when they are tired or ill. for example, a cup of water, a sweet greet, even a sweet smile can make them better. The most important thing I should do is to do well in my lessons.this is what they care about most.
Why shall I do so? it seems not a question. I love my father and mother , I LOVE MY FAMILY.I want them to be happy all the time and I will try my best to realize my dream.
