What's ten plus ten?

And one more?

It's twenty.

It's twenty-one.

Right.

Good friends

    Hi, I am Lili. I have got two good friends. One is Ting, the other is Ding. Ting is a girl. She is very nice, she always helps me. But she is a bit quiet. Ding is a boy, he is very clever. He can make birthday cards. But he is a bit naughty, he always plays in class. At the weekend, we often go swimming together.

Is it climbing the tree?

Look! This monkey is very clever.

Oh! And very naughty, too.

Yes, it is.
