She tried the key in the lock and the door opened. Outside the door was a beautiful garden. Alice wanted to go outside,but she was too big to go through the little door. She closed the little door and went back to the table. Now there was a bottle on it. A label on the bottle said: " DRINK ME!" Alice looked carefully at the bottle,then she tried the drink. It was delicious! It tasted like all her favorite foods at the same time,so she drank eat all. "I feel very strange," Said Alice. She looked up and saw that the table was high above her. "I'm small!" She said. "Now I can go into the garden!" But the key to tell little door was on the table. Alice could see it, but she couldn't reach it. "Oh no!" Said Alice. Just then, she saw a little glass box on the floor. Inside, there was a tiny cake with the words "EAT ME!" On it. Alice ate the cake. "Oh!" She said. "Now I'm growing!"
