Today is Sunday. Jill and Tom are in the park. They see some grass under a big tree. It's green and soft. They want to sit under the tree. They put a towel(毛巾) on the grass. They sit on the towel. Jill feels something cold and hard. It's a stone(石头). Tom feels something soft, wet and thin. What is it? Wow, it's a snake(蛇)! They are afraid.

Alice：Touch this, Tom. How does it feel?

Tom：It's soft. Is it a doll?

Alice：No, it isn't. It's a toy bear. It's brown.

Tom：I don't like toy bears, but I like robots.

Alice：Touch this, Kitty. How does it feel?

Kitty：It's hard and thick. Is it a book?

Alice：Yes, it is. Well done, Kitty. Do you like reading books?

Kitty：Yes, I do.
