Should we help our parents do some housework?

students should help our parents do some housework.

Firstly,after a whole day's work, our parents must be very tired. If we help them with the housework, they'll feel quite happy and pleased.

On the other hand, doing housework not only train our ablities, but also help us make a sense of resposibility. Only through housework can we realize we're members of our families, then to realize we're parts of our society.    We can devote ourselves to the world.

So, I think it necessary for us to do some housework.
