B
Alice was now in a long dark room with doors all round the walls, and she could not see the white rabbit anywhere.
She tried to open the doors, but they were all locked (上了锁的). "How will I get out again?" she thought sadly. Then she saw a little glass table with three legs, and on the top of it was a very small gold key. Alice quickly took the key and tried it in all the doors, but she couldn't open any.
Then she saw another door.The door was only forty centimetres high. The little gold key unlocked this door easily, but Alice couldn't get through it—she was much too big. So she lay on the floor and looked through the open door into a beautiful garden with green trees and bright flowers.
"I'd like to be out there—not in this dark room. Why can't I get smaller?" It was already a very strange day, and Alice was beginning to think that anything was possible.
After a while she locked the door again, got up and went back to the glass table. She put the key down and then she saw a little bottle on the table. Round the neck of the bottle was a piece of paper with the words "DRINK ME" in large letters.
"It can be dangerous to drink the liquid(液体) in the bottle," she said. "What will it do to me?"She drank a little bit very slowly. The taste was very nice and very soon Alice finished the bottle.
"I think I'm getting smaller and smaller every second, " she said. "And now, " she said happily, "I can get through the little door into that beautiful garden."
She ran at once to the door. Then she remembered that the little gold key was back on the glass table. She ran back to the table for it, but she was now much too small! The key was high above her, on the top of the table. She tried very hard to climb up the table leg, but she couldn't do it.
At last, tired and unhappy, she got angry with herself. Soon she saw a little glass box near her on the floor. She opened it, and found a very small cake with the words "EAT ME" on it.
Nothing could surprise Alice now.
