Song Hua and his mum are talking at home.

Song Hua’s mum: Wow! How clean and tidy our house is！

Song Hua: Yeah! I cleaned my bedroom first, and then I cleaned the living room too. It took me one hour to sweep the floor, clean up the things on the desk, and dust the shelves. A clean and tidy house can make us feel happy.

Song Hua’s mum: That’s wonderful, Song Hua! You’ve learned the importance of doing housework, haven’t you?

Song Hua: Yes, Mum. I’m so tired after all that work. And you always do these things for our family. As a member of the family, I should share in your work. Mum, you are great!

Song Hua’s mum: Thank you, Song Hua! You are a good son.
